Abstract

The utility model provides an injection mold. The injection mold comprises a fixed mold and a movable mold, wherein the movable mold is provided with a molding cavity, a flow passage, an injection hole and a ventilation hole, the injection hole is communicated with the molding cavity through the flow passage, and the ventilation hole is communicated with the molding cavity. The injection mold is characterized by further comprising an air pump, an ejector rod and a spring, wherein the air pump is communicated with the ventilation hole, the spring and the ejector rod are located on the movable mold, the spring is connected with one end of the ejector rod, and the other end of the ejector rod can extend into the molding cavity. Through additionally arranging the air pump, the air pump pumps air out of the molding cavity during injection molding, so as to lower the pressure of the air in the molding cavity, increase the speed of injection molding and improve the quality of injection molding, the air pump pumps air into the molding cavity during demolding, so as to enable the surface of a molded part to be smooth, thus, the demolding is facilitated, the quality of the molded part is stable, and the work efficiency is obviously increased; due to the spring and the ejector rod, after demolding, the ejector rod ejects into the molding cavity, so that the separation of the molded part from the movable mold is facilitated, manual operation is not required, and the work efficiency is increased.

Description

A kind of injection mold
Technical field
The utility model belongs to injection machine technical field, relates in particular to a kind of injection mold.
Background technology
Injection mold is widely used in plastic product processing industry.Injection mold is generally adapted to thermoplastic hot briquetting.Utilize the hot melt principle of thermoplastic, the plastics of melting are injected into by injection machine in the die cavity of mould, then cooling and shaping, opens mould and takes out plastic product.In mold injection process, because the air pressure in die cavity is larger, affect injection moulding quality and speed, cause unstable product quality, operating efficiency is not high.Plastic generally needs manually from dynamic model, to take out, inefficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of injection mold, comprise fixed half and moving half, described dynamic model is provided with die cavity, runner, injection orifice and passage, described injection orifice is communicated with described die cavity by runner, described passage is communicated with described die cavity, characterized by further comprising air pump, push rod and spring, described air pump is communicated with described passage, described spring and push rod are positioned on described dynamic model, described spring is connected with described push rod one end, and the described push rod other end can stretch in described die cavity.
The beneficial effects of the utility model are: add air pump, when injection moulding, air pump is extracted the air in die cavity out, reduce the air pressure in die cavity, improve injection moulding speed and quality, when the demoulding, in die cavity, inject air, make plastic surfacing, be beneficial to the demoulding, plastic part quality is stable, and operating efficiency obviously improves; Utilize spring and push rod, after the demoulding, push rod heads in die cavity, is beneficial to the disengaging of plastic and dynamic model, without manual operations, has improved operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, cover half; 2, dynamic model; 3, die cavity; 4, runner; 5, injection orifice; 6, passage; 7, air pump; 8, push rod; 9, spring.
As shown in Figure 1, cover half 1 mates with dynamic model 2, dynamic model 2 is provided with die cavity 3, runner 4, injection orifice 5 and passage 6, injection orifice 5 is communicated with die cavity 3 by runner 4, passage 6 is communicated with die cavity 3, and air pump 7 is communicated with passage 6, and spring 9 and push rod 8 are positioned on dynamic model 1, spring 9 is connected with push rod 8 one end, and push rod 8 other ends can stretch in die cavity 3.
Have been described in detail of the present utility model by embodiment above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
