Abstract

The utility model discloses a safety boot die. The small bottom cover and the big bottom cover of the safety boot are arranged at the left side and the right side of a die body. Mold cavities are arranged at the internal sides of the small bottom cover and the big bottom cover respectively. A first injection port is arranged at the left and right parting surface of the die body, and a second injection port is arranged at the joint breaking surface of the die body and the small bottom cover and the big bottom cover. A boot last and a boot sole are cast with the technique of die casting and secondary injection to complete the plastic injection of full PU materials for a long safety boot. In this way, a material handle will not block an injection hole easily and can be taken away easily, so as to promote the production efficiency greatly.

Description

The working boot mould

Technical field

The utility model relates to a kind of working boot mould, particularly can make the working boot mould of PU material injection mo(u)lding.

Background technology

Present domestic producer and the matching die of not producing full PU boot injection, the producer that domestic youngster family produces the PU footwear just adopts the production of die sinking pouring type, and product quality is extremely unstable.The plastics boots that wherein domestic employing injection moulding mode is produced, the structure of its mould is that the side cover at mould top is opened left, the mode that big bottom is opened backward, rear side can't be offered the major ingredient hole, the material of its generation is being embedded in the material hole of mould, need firmly will expect taking out, and the characteristics of PU material to be PU expect to be bonded on the mould easily, material takes off more difficult, has a strong impact on production efficiency.

Summary of the invention

Problem to be solved in the utility model overcomes injection molding material exactly being embedded in mould material hole, and after injection moulding was finished mould and opened, the boots material was the shortcoming of taking off difficulty.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is that little bottom of boots and the big bottom of boots place the die main body left and right sides respectively, and little bottom of boots and the big bottom of boots inboard are respectively equipped with die cavity; Die joint place, the die main body left and right sides offers first cast gate; Little bottom of die main body and boots and the common somatotype of the big bottom of boots place offer second cast gate.

Described pouring type is for adopting the mold closing cast.

Advantage and the good effect that the utlity model has are: owing to offer two cast gates in the die main body side, utilize crunch to adopt the mode of mold closing injection at twice to be expelled to mold cavity in by two mould gates PU footwear material, utilize the technology of biphasic injection to pour into a mould at the bottom of boot upper, the boots, finish the injection moulding manufacturing of the full PU material of long working boot.Because plug hole at the die joint place, after mould is opened, expects nature is come off by the die joint place, be very easy to again, be not easy the shutoff sprue gate.

Description of drawings

Fig. 1 is the working boot die structure dwg;

The little bottom of 1 boots, the big bottom of 2 boots, 3 die main bodies, 4 cast gates for the first time, 5 mold cavities, 6 cast gates for the second time.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1: boots handle lid 1 places die main body 3 left and right sides respectively with the big bottom 2 of boots, and die joint place, die main body 3 left and right sides offers first cast gate 4; Die main body 3 is offered cast gate 6 for the second time with boots handle lid 1 and the big bottom of boots 2 common somatotype places.During production the little bottom of boots is built, utilize mode that crunch adopts the mold closing injection with the PU material by the first time cast gate 4 be expelled in the mold cavity 5, finish the cast of boot upper.After treating that group's material solidifies, open boots handle lid 1, the big bottom 2 of the boots that close from the big end of the cast gate cast boots moulding boots second time, is promptly finished the injection moulding manufacturing of the full PU material of rubber rain jack boots working boot with the same manner after bed material solidifies.Casting sequence at the bottom of boot upper and the boots also belongs to the protection domain of this patent.

Claims
