Description

Optical component mould structure

Technical field

The utility model in relation to a kind of optical component mould structure, it is espespecially a kind of provide can avoid injection-moulding plastic object in The missing for being scraped off or deforming when being detached from the molding chamber of male die core generates, and optical component mold is made more to can be suitably used for super-thin The injection moulding of optical component uses the optical component mould structure of effect whereby to promote the optical component mold.

Background technique

It presses, optical component mold 1, as shown in Figure 1, 2, which has master mold 11 and male model 12, is equipped in the master mold 11 A plurality of mother module core caves 111 are inserted with mother module core 112 in the mother module core cave 111, and the end of the mother module core 112 is recessed with molding Chamber 113；The male model 12 corresponds to master mold 11 and also is provided with a plurality of male die core caves 121, is inserted with male model in the male die core cave 121 Benevolence 122, the end of the male die core 122 is also opposite to be recessed with molding chamber 123, and the molding chamber 113,123 is interior for the plastics Injection moulding.

As shown in Figure 1, 2, to allow optical component that can smoothly complete the movement of demoulding, dealer can be in the male model of the male model 12 An ejector pin 13 is arranged in 122 side of benevolence, by the ejector pin 13 carrys out ejection stock column A, is detached from public affairs whereby to enable the optical component molding The molding chamber 123 of mode 122, and then to complete the stripping action of the plastic shaping object.

The above-mentioned optical component mould structure 1 commonly used assists plastics to infuse by being arranged an ejector pin 13 on the male model 12 Molding demoulding is penetrated, can no doubt achieve the purpose that the convenient demoulding of optical component.However, work as the optical component excessively light and smallization, Such as optical mirror slip, due to the optical component mold 1 commonly used, the male die core 122 of ejector pin 13 and the male model 12 possess one section away from From, therefore the top heap point A1 that will cause the optical component and stock column A has a long arm of force, so working as the 13 ejection stock column of ejector pin A come enable the optical component object be detached from male die core 122 molding chamber 123 when, be very easy to cause the optical component in the male model The thing for scratching or deforming is generated in the molding chamber 123 of benevolence 122, and then the optical component becomes faulty materials and discarded.

Therefore a kind of optical component mould structure how is provided, to avoid the optical component when demoulding in molding chamber It is inside scraped off or deforms, project urgently to be resolved for injecting molding die manufacturer.

Utility model content

The technical issues of the utility model is solved is to be to provide a kind of optical component mould structure, can overcome habit whereby With optical component when being detached from the molding chamber of male die core, it is easy to produce the missing for being scraped off or deforming.

Technological means used by the utility model is as follows.

The utility model is in order to achieve the above object, used technical way is: providing a kind of optical component mold Structure, the mold include a master mold and one can male model corresponding with the master mold, which at least has a master mold pad, should Master mold pad is equipped at least one mother module core cave, and mother module core is equipped in the mother module core cave, and the end face of the mother module core is equipped with forming cavity Room, the molding chamber material path；The male model at least has a male model partition and a male model pad, which is equipped with extremely Lack a male die core cave, male die core is equipped in the male die core cave, the end face of the male die core is equipped with molding chamber, the molding chamber Material path；The male model baffle central has holding part, which has been installed with an activity board group, and activity board group side connection one pushes away Motion block, the activity board group are equipped with a plurality of male die core push rods and a plurality of ejector beams, which connects the male die core, should Ejector beam is connected to the material path；The male die core push rod can release the molding chamber of the male die core outside the male model pad whereby, and be somebody's turn to do Ejector beam the pushing tow material path can be formed by stock column and release outside the male model pad simultaneously.

The utility model has the advantages that existing the effect of the utility model can be reached by above-mentioned technological means caused by the utility model In: have holding part by the male model baffle central, which has been installed with an activity board group, and activity board group side connection one pushes away Motion block, the activity board group are equipped with a plurality of male die core push rods and a plurality of ejector beams, can avoid optical component injection moulding whereby The missing for being scraped off or deforming when being detached from the molding chamber of male die core afterwards generates, while the optical component can be made in injection moulding It avoids generating the notch of processing in the non-optical zones afterwards, and then process engineering of the optical component after injection moulding can be simplified, The injection moulding that can make optical component mold more and can be suitably used for the optical component of super-thin simultaneously, carrys out improving optical component dies whereby Use effect of tool.
