Overmolding refers to secondary forming process, refers to that thermoplastic elastomer (TPE) arrives a kind of injection moulding process of engineering plastic by melting adhesive bond.Simply saying, is exactly plastic product of first moulding, then this product is put into another plastic cement of injection moulding in an other mold, thereby becomes a technique that has the product of two kinds of plastic cement.Common twice plastics of overmolding are all the plastics of hardness more than 80 degree, because plastic cement mobile poor for the second time not too easily runs burr, mould development is relatively simple.Also having a kind of situation, is once the plastic cement that hardness is higher, and secondary is that hardness is at the flexible glue of 50 degree left and right.Such as handle or the sealing position of some structural members, be all that flexible glue is attached on ebonite, the exploitation of this product is comparatively complicated, and the mobility of secondary flexible glue is very good, extrudes a little the space of 0.02mm left and right and will run out of burr.Such as the handle of the hand-held POS machine occurring on the market at present, except sealing place has flexible glue, internal structure place also has flexible glue.The exploitation of this mould just has very large difficulty.Be mainly reflected in: primary production internal structure is by mold insert moulding, then while wrapping flexible glue, be difficult to plastics to compress, in situation about not pressing tightly, easily run out of burr; The internal structure of structural member, can slightly be out of shape because of the internal stresses release after formed product, and such product inserts secondary mould and is difficult to insert, and product is easily weighed wounded.Product inserts secondary mould on the one hand need precompressed sealing, product can not too tightly be avoided again cannot inserting or being weighed wounded by secondary die cavity on the other hand, process such process bothers very much, conventionally after die trial, flexible glue produces burr, burr place is added after iron processing, there will be again primary production to insert, tension or interference place are subtracted after iron, secondary flexible glue can run burr again, this circulation meeting mould engineer and pincers worker do badly batteredly, without from, certainly mould development cost also can be climbed to a higher point successively, and mold developing cycle can draw very longly.
For this series products, need to there is so a kind of mould, both can guarantee that primary production conveniently packs into, afterproduct does not go out burr, thereby can make mould development cost, the cycle shortens.
Utility model content
The utility model provides a kind of overmold mould that wraps flexible glue, has realized a kind of mould of guaranteeing that primary production conveniently packs into, afterproduct does not go out burr.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of overmold mould that wraps flexible glue, the male model and the master mold that comprise mutual coupling, described master mold mainly consists of some slide blocks, between every slide block and male model, all adopt rail structure, after all slide block matched moulds, form and the die cavity that needs bag flexible glue product to mate, the poor 0.03mm that is less than of matched moulds of adjacent sliders matched moulds with male model.
Described master mold mainly consists of two slide blocks, and described two slide blocks are arranged on same slide rail and can relatively move.
The sealing position of the described die cavity with needing bag flexible glue product to mate adopts insert structure.
Described sealing position adds iron 0.03mm.
Outside the sealing position of described die cavity, to do the degree of depth be 0.1mm empty avoiding at 2mm place.
Between described sealing face and empty avoiding, pass through a cambered surface transition.
The beneficial effects of the utility model are: 1, master mold of the present utility model mainly consists of some slide blocks, after all slide block matched moulds, form and the die cavity that needs bag flexible glue product to mate with male model, adopt this kind of structure to facilitate primary production to pack into, the poor 0.03mm of being less than of matched moulds of adjacent sliders matched moulds has guaranteed that afterproduct does not go out burr simultaneously; 2, adopt insert structure with the sealing position of the die cavity that needs bag flexible glue product to mate, sealing position adds iron 0.03mm, has guaranteed to seal flexible glue; 3, outside the sealing position of die cavity, to do the degree of depth be 0.1mm empty avoiding at 2mm place, between sealing face and empty avoiding, by a cambered surface transition, guaranteed when primary production packs into not tightly, and cambered surface avoids scratch need wrap flexible glue product inwall.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
