The clearance of 003, plus the clearance that accumulates an error, in order to prevent both between adhesion and bite into. To major mould, this is insufficient, still need farther locking part, make sure its are noting the correct position below force of model frit hydraulic pressure, keep stable shape a ply. Calibration locking orgnaization basically has the following 3 large main types: Contain the plug type of taper and circular locking orgnaization; Flank and coping contain the flat locking orgnaization of needle bearing; What flank and coping contain taper is flat combine locking orgnaization with roller bearing type. Cone-shaped locking orgnaization 1.
Orgnaization of this kind of locking basically uses orgnaization of locking of cone-shaped bolt type at preventing model core notes the deflection in model process in frit fluid. Orgnaizations of all locking of cone-shaped bolt type, use a taper to be more than the awl of blame locking type of 7 to cover commonly, and every side of major locking device uses a taper to be covered for the awl of 10. Device of locking of long strong pattern cannot be the rectangle that contains bigger locking to contact force model the protection of core provides inchoate calibration function, close completely when the mould only when, ability provides an accurate place. Before installing orgnaization of plug type locking, still must expand considering heat problem. When difference in temperature is close to 10 F, will be in 24in (1in=25.
4mm) the generation on length 0.
The interference coefficient of 0015. According to mould temperature and dimension different, this interference element may bigger. The installation of orgnaization of locking of cone-shaped bolt type should expand with heat from beginning to end direction keeps parallel, but the flexibility of position of installation of this inevitable meeting limitation. 2.
Orgnaization of this kind of locking regards the circular locking orgnaization that takes taper as positioner only commonly use. As orgnaization of locking of cone-shaped bolt type, they cannot are model core offers inchoate calibration or protect, because its have the interface of 360, because this still must consider,heat up expanding problem. Leave larger mould base to the span of positioner, do not recommend use tape commonly the circular locking device of taper. When the distance between positioner is lesser, recommend normally insert in the mould receive in use the circular locking orgnaization that takes taper, can make heat expands so fall lowest. Flat locking orgnaization 1.
Flat locking orgnaization this is a kind of the most extensive locking orgnaization that uses in industry. Besides material, coating, grease, groove and black lead outlet, the locking orgnaization blueprint between all manufacturers is same actually. Use flat locking orgnaization to be able to solve the problem that heat expands, allow locking orgnaization to move freely on a direction, still can hold the position on opposite way at the same time. Install 4 locking orgnaization to be able to make sure the mould is in central position from beginning to end, without giving thought to mould how does half two difference in temperature change. The basic design of every locking orgnaization is comprised by shade, positive element, every one side has a space of thousand. 2.
This locking orgnaization uses orgnaization of standard flank locking at the lock to decide the position of the mould, the help overcomes the pressure of fluid of the frit that note model. According to special outline appearance, the inchoate clench the teeth that flank locking orgnaization can offer minor rate is protected (see a picture 1) . Flank locking orgnaization is machined on central axes commonly, those who include to go up in the side outside the mould is perpendicular machine with the level. Put apart of requirement of flank locking orgnaization most the installation space of at least. When the recess that machines locking orgnaization, should the mould half two clamp, in order to assure a mould the two positions of half are parallel. Generally speaking, flank locking orgnaization can reach the designated position very easily with accurately installation. Graph the outline appearance with 1 special basis, the inchoate clench the teeth that flank locking orgnaization can offer minor rate is protected 3.
Coping locking orgnaization of the standard as flank locking orgnaization, these coping locking orgnaizations can provide the protection of clench the teeth of minor rate, lock up emplacement next, overcome the pressure of fluid of the frit that note model. Coping locking orgnaization is commonly on central axes undertake machining, those who include to go up from mould face is perpendicular machine with the level. Coping locking orgnaization should resemble directing sell and direct set in that way, in the treatment inside same time, make sure its parallelism is mixed oriented sold relative position. But orgnaization of unlike flank locking in that way, coping locking orgnaization is cent second debug a setting to machine, ask to achieve the treatment precision of higher rate. 4.
The locking orgnaization that takes needle bearing this is relative to newer innovatory achievement, its purpose is to overcome a standard the defect that orgnaization of flat type locking exists in the design, especially the clench the teeth with this original orgnaization. The elevate force that sheet ordered radial contact to offer a blame to bind type comes calibration sinks mould, this is a kind of very effective calibration method. The locking orgnaization that contains needle bearing can provide protection of some kind of inchoate clench the teeth, but in using the final lock of only point contact to decide a process, if want to overcome the pressure of fluid of the frit that note model, do not accord with a mould to make the worker's wish apparently. Although Nextpage is flat type locking orgnaization is considered as component of a kind of calibration, but their support is oriented sell and direct set come calibration mould, make its have the function of locking device thereby. Say exactly, if the mould is new,contain the quadrate component that machines through simplifying molded lines recess, new oriented sell and direct set, and when the new machine noting model that distributes pressing plate of form of in the right way, orgnaization of flat type locking has the level faultlessly worked. However, in actual production, although noting the pattern with the new application on model machine, but what what deploy is tatty department staff and oriented set, because of,the mould also is met self-prossessed and flagging, be down and tilt ahead. Sheet relies on to direct annul cannot provide proper place, make its enter orgnaization of flat type locking smoothly, have only because of this orgnaization extremely 0.
The clearance of 0002, this will affect them surely between cooperate (see a picture 2) . 0.
The amlposition of 1 will bring about 0.
The interference of 00022. And the amlposition of 2 can build thousand to divide 0.
The interference of 0072, because this assured,clutch and bind a problem. Graph 2 certain levels are flat the orgnaization of locking of calibration of combined-type of inchoate clench the teeth of type and orgnaization of Trinitarian type locking carries out a proof, the locking orgnaization that contains roller bearing is one of best locking device on the world (see a picture 3) , this is orgnaization of a kind of combined-type calibration locking that contains new patent technology, it will be contained cone-shaped, flat model be united in wedlock together with the optimal characteristic of the locking orgnaization of needle bearing, have additional good point. Graph the 3 locking orgnaizations that contain roller bearing above all, begin from the first phase of primary calibration, the locking orgnaization that contains roller bearing is the large roller that uses hard processing of temper by dipping in water, radius of a promotion is contained on its moon face, when although be in,producing bigger mould amlposition, this promotion radius also makes can easy to doly its clench the teeth. In the 2nd phase, the calibration of orgnaization of roller bearing locking can provide protection of inchoate clench the teeth to the greastest extent, and but up to mark is flat model double with length of orgnaization of locking of needle bearing type, but physical size is same. The 3rd phase is affirmatory and ultimate locking force. The taper horn of face of its this world is 5, have the character that whole journey protects, can assure the most close together public errand, make its can achieve the largest clamping force. The locking orgnaization that contains roller bearing asks to use as flat as the standard model the treatment method with locking same orgnaization. Below a lot of circumstances, it also has the space of same size, it is very easy to change. The locking orgnaization that contains roller bearing uses symmetrical type design, because very tall interchangeability is had between this shade, positive element. The design of orgnaization of locking of roller bearing type and longer life expectancy can make sure its move 1 million times. Current, the contains roller bearing locking orgnaization that can offer, agree with flank and coping application, have the following advantage: Can realize earlier amlposition clench the teeth easily; Provide protection of the longest inchoate clench the teeth; Have as far as possible high locking power; Almost as identical as the space that at present locking orgnaization place occupies; Component of shade, in relief double is OK crossing-over; Although amlposition is in 5 times, also can reach the interference level of micron class, and can be eliminated mix solve a few difficult problem; Can reduce the upkeep costs in process of whole pattern life. Need to undertake what kind of calibration no matter, must be in choose appropriate a few factors consider before locking orgnaization: The state of the condition of the machine that note model, mould, fall mould upkeep costs the importance when lowest, stop production time that reduces a mould as far as possible, stable quality that assures mould spare parts, without attrition flowing clench the teeth, inchoate clench the teeth is mixed assure bedspring length and long-term locking force.
