Description

Pop-up double push plate secondary ejection mold

technical field

The utility model relates to a secondary ejection mold of a pop-top double push plate.

Background technique

Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Sometimes due to the special shape of the plastic part or the needs of production automation, the plastic part is still difficult to take out from the cavity or cannot fall off automatically after one demoulding and pushing action, and it is necessary to add another demoulding and pushing action to make the plastic part demould; Sometimes in order to avoid excessive force on the plastic part when the first demoulding is pushed out, the secondary demoulding is also used to ensure the quality of the plastic part. This type of demoulding mechanism is called the secondary ejection device. The traditional secondary ejection device has complex structure, poor ejection effect, high product rejection rate and high cost.

detailed description

The utility model is described further in conjunction with accompanying drawing now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.

As shown in Figure 1, the pop-top type double push plate secondary ejection mold includes a support plate 9 on which a plastic part molding assembly and a plastic part ejection assembly are installed, and the plastic part forming assembly includes a support plate 9 On the core seat 10, the outer side of the core seat 10 is provided with a movable model cavity plate 1, and the center of the core seat 10 is provided with a core 3 extending into the movable model cavity plate 1; the ejection assembly of the plastic part includes a push plate 7, One side of the primary push plate 7 is provided with a secondary push plate 6, and the other side of the primary push plate 7 is fixedly equipped with a push rod fixed plate 11, and the push rod fixed plate 11 is located between the primary push plate 7 and the support plate 9; A secondary push rod 2 for ejecting plastic parts is vertically provided on the plate 6 , and a primary push rod 4 for ejecting the model cavity plate 1 is vertically provided on the push rod fixing plate 11 .

The limit screw 5 that limits the position of the secondary push plate 6 is installed on the primary push plate 7, and the part of the limit screw 5 protruding from the secondary push plate 6 is provided with a spring 8; the secondary push rod 2 passes through the primary push plate 7 , the push rod fixed plate 11, the support plate 9, the core seat 10 and the movable model cavity plate 1 are in contact with the plastic part; The guide post 12 to which the plate 11 is guided.

When pushing out, the ejector pin of the injection machine pushes the push plate 7 once, drives the push rod 4 once to move the movable model cavity plate 1, and the plastic part is released from the core 3, and one push is completed. Simultaneously, the primary push plate 7 drives the limit screw 5, so that the spring 8 is compressed, and impels the secondary push plate 6 and the secondary push rod 2 to move simultaneously. When the spring 8 is compressed to a certain extent, its elastic force pushes the secondary push plate 6 and the secondary push rod 2, and the plastic part is pushed out from the driven model cavity plate 1, and the secondary push is completed.

This pop-top double push plate secondary ejection mold has a simple structure, reasonable design, and more convenient installation and maintenance. Through the mutual cooperation between the primary push plate 7, the secondary push plate 6, the limit screw 5 and the spring 8, The secondary rollout effect is good, the product quality is improved, and the production speed is accelerated.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
