Description

Injection moulding cuts composite die

Technical field

The injection moulding that the utility model relates to a kind of all waste materials on can disposable excision injecting products cuts composite die.

Background technology

Now some product needed adds plastic skeleton as approved product with soft material, and as the filter screen of air-conditioning, it is exactly that the mould that filter screen is put into injection machine is carried out injection moulding, after injection moulding is finished, takes out semi-finished product, manual burr and the waste material repaired.

Also having is exactly the existing housing that is widely used on the electronic installations such as phone, computer, game machine.In order further to make housing have good sense of touch, available technology adopting a kind of outermost layer that is arranged on this housing by leather, fabric etc. for the soft layer of material.In the process of making this housing, earlier soft layer is put into mould and carry out injection mo(u)lding, then the semi-finished product that form are taken out again that edge is unnecessary soft layer and shear to form this housing.

Have now and handle this moulding that has soft material, not only procedure of processing is loaded down with trivial details, but also has increased manufacturing cost, especially now continuous rise present of cost of labor.

Chinese patent literature 101531049 discloses a kind of injection mold, and it comprises a master mold and a male model that matches with this master mold, and this male model and master mold convex with the cut part on one of them, offer accepting groove on another, to accommodate described cut part.Injection mold can cut off unnecessary soft layer and carry out injection mo(u)lding in male model and master mold matched moulds, saved the die-cut tool of later use or other cutting tools soft layer is sheared step, has saved process time greatly, has improved working (machining) efficiency.

But this injection mold, be in matched moulds, by the cut part that is convexly equipped with and the acting in conjunction of accepting groove, after cutting off unnecessary soft layer, carry out injection mo(u)lding again, promptly first cutting waste material, the way of injection moulding again, in the process of injection moulding, produce new burr again if exist, still needed problem artificial or remove burr again with other cutting tool.

The utility model content

In order to address the above problem, the utility model to society provide a kind of can disposable solution plastic parts burr or the injection moulding on waste material limit cut composite die.

The technical solution of the utility model is: provide a kind of injection moulding to cut composite die, comprise dynamic model and cover half, be provided with in the described dynamic model outside and cut part, the described part that cuts is connected with drive unit away from an end of die joint; Be provided with pressure part in the described cover half outside with the described corresponding position of part that cuts, be provided with return springs away from an end of die joint at described pressure part.

As to improvement of the present utility model, be provided with lead at the end away from die joint of described pressure part.

As to improvement of the present utility model, described return springs is a spring.

As to improvement of the present utility model, be provided with alignment pin or locating hole on the part described cutting, on described pressure part, be provided with locating hole or alignment pin, during matched moulds, described alignment pin just in time is inserted in the described locating hole.

As to improvement of the present utility model, described drive unit is drive device for hydraulic or actuating device of atmospheric pressure.

As to improvement of the present utility model, the described part that cuts is a cutting die.

As to improvement of the present utility model, the described lateral wall that cuts part and described cover half closely file closes.

Because the utility model employing is provided with in the junction of finished product material and waste material and cuts part and pressure part, and be used to drive the drive unit that cuts part, after injection moulding is finished, before not having die sinking, drive by drive unit and to cut part, all waste materials on can disposable excision injecting products.Therefore, the utlity model has saving of work and time, save cost and improve the advantage that the worker leads.

The specific embodiment

See also Fig. 1 to Fig. 3, what Fig. 1 to Fig. 3 disclosed is that a kind of injection moulding cuts composite die, comprises dynamic model 1 and cover half 2, is provided with in described dynamic model 1 outside and cuts part 12, and the described part 12 that cuts is connected with drive unit 3 away from an end of die joint; On described cover half 2, be provided with pressure part pressure part 22 with the described corresponding position of part that cuts, be provided with return springs 23 at described pressure part 22 away from an end of die joint, in the present embodiment, described return springs 23 is springs, obviously, return springs 23 also can adopt other rubber-like object to replace.In the utility model, what be oppositely arranged cuts the junction that part 12 and pressure part 22 preferably are located at finished product material and waste material.

In the utility model, be provided with lead 24 at the end away from die joint of described pressure part 22, described lead 24 is connected with described solid plate 4; Cutting described that to be provided with alignment pin 121 on the part 12 certain, also can be locating hole, and to be provided with locating hole 221 also can be alignment pin to pressure part 22 on described, and when matched moulds, described alignment pin just in time is inserted in the described locating hole, and both are precisely located.In the utility model, described drive unit 3 can adopt drive device for hydraulic, also can adopt actuating device of atmospheric pressure, can also adopt other power set, cuts part 12 and moves just passable as long as can drive.In the present embodiment, the described part 12 that cuts is cutting dies.In order better to cut, the described lateral wall that cuts part 12 and described cover half 2 is preferably closely filed and is closed.

See also Fig. 4, the utility model in use, earlier cover half 2 is installed on the solid plate 4, allow die cavity 41 communicate with runner 42 and sprue bushing 43, dynamic model 1 is contained on the moving platen 5, and set ejector pin mechanism 6 and thimble 61, and and setting and be used to drive the drive unit 3 that cuts part 12, drive unit 3 drives and cuts part 12 by driving cross bar 31 and drive link 32.Whole injection moulding process is divided into: add soft material, and as silk screen, leather, fabric etc., matched moulds, drive unit is opened in injection moulding, promotes to cut part excision waste material, and finished product is taken out in die sinking.
