The die-cut integrated mould of a kind of injection moulding
The utility model discloses the die-cut integrated mould of a kind of injection moulding, divides belong to composite die manufacturing technology field by International Patent Classification (IPC) (IPC).
Present product structure design becomes increasingly complex, and all can there be the needs laying inserts a lot of injecting products inside.In the ordinary course of things, the injection moulding of the shaping and product of inserts separates, and inserts is all by stamping die through bending, the multistage operations such as punching complete shaping after, be placed directly on injection mould fixing, complete the plastic products with inserts by injection moulding, therefore, formed product operation is more, cost is high, this situation can consider simpler punching operation to combine with injection mould, designs the die-cut integrated mechanism of a kind of injection moulding, therefore just the utility model proposes.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the die-cut integrated mould of a kind of injection moulding, by increasing the punching operation of inserts on injection mould, injection mould and perforating die are combined, make product reduce molding procedure, save production cost, enhance productivity.
For achieving the above object, the utility model is achieved through the following technical solutions:
The die-cut integrated mould of a kind of injection moulding, comprise the cover half of dynamic model and cooperation, cover half part install springing drift be used for die-cut be placed in dynamic, fixed between fixing inserts, dynamic model and cover half are respectively equipped with mavable module core and fixed mold core, the die cavity of injection moulding inserts is formed between die, this die cavity communicates with the cast runner be arranged on cover half, and is provided with sprue bush outside the vertical-sprue of cover half part.
Further, described dynamic model is provided with the slug hole corresponding with cover half drift, and mavable module core is run through in this material hole.
Further, described cover half also comprises solid plate and panel, and solid plate and panel are connected and fixed by spring and limited screw, drift one end wherein and plate contact, and drift is die-cut inserts through solid plate and fixed mold core.
Further, described dynamic model also comprises moving platen, ejector retainner plate and base plate, and moving platen is fixedly connected with base plate, and ejector retainner plate is arranged at the also energy knee-action between moving platen and base plate and drives thimble for ejecting injection moulding inserts.
The present invention relates to the advanced composite mold mechanism of the die-cut integration of a kind of injection moulding; belong to advanced manufacturing; the utility model installs drift in injection mould; the molding procedure of inserts combined with the program procedure of goods, effective minimizing formed product operation, meets product structure requirement; there is simplification production process; save production cost, the feature of enhancing productivity, has very large promotion prospect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 4, the die-cut integrated mould of a kind of injection moulding, the cover half 2 comprising dynamic model 1 and coordinate, dynamic model partial fixing inserts M, cover half part installs springing drift 3 for die-cut insert-molding, dynamic model and cover half is respectively equipped with mavable module core 11 and fixed mold core 21, forms the die cavity of injection moulding inserts between die, this die cavity communicates with the cast runner be arranged on cover half, and is provided with sprue bush 4 outside the vertical-sprue of cover half part.Dynamic model 1 is provided with the slug hole 100 corresponding with cover half drift, and mavable module core is run through in this material hole.Cover half 2 of the present utility model also comprises solid plate 22 and panel 23, and solid plate 22 and panel 23 are connected and fixed by spring 241 and limited screw 242, drift one end wherein and plate contact, and drift is die-cut inserts through solid plate and fixed mold core.Dynamic model 1 also comprises moving platen 12, ejector retainner plate 14 and base plate 15, and moving platen 12 is fixedly connected with base plate 15, and ejector retainner plate 14 is arranged at the also energy knee-action between moving platen and base plate and drives thimble for ejecting injection moulding inserts.
The utility model general principle:
Before mould matched moulds, non-punching inserts is fixed on injection mould dynamic model part, drift is installed on stationary mould for mould part, is fixed on panel, and panel is connected by spring and limited screw with solid plate, can flick 5mm.During mould matched moulds, dynamic, fixed mold core contacts, and pushes down inserts, prevents inserts from going to.Mould continues matched moulds, the die-cut inserts of drift, until complete matched moulds, inserts M completes puncture motion, and waste material die cutting M0 drops from die waste hole.After complete matched moulds, injection machine injects the plastics melted by sprue bush, at in-mold molding plastic products.After cooling forming, mould die sinking, ejects die-cut moulding.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
