technical field

The utility model relates to the technical ejection structure mold field, in particular to a sliding block ejection structure mold.

Background technique

A mold is a tool for forming objects, and it is widely used in various industries. The mold of the prior art comprises an upper mold solid plate, an upper template, a lower template, a lower mold solid common plate, a mold foot and an ejector device, and the upper template and the lower template form the cavity of the product after mold closing. The ejector device in the prior art is usually composed of ejector rods. The lower end of the ejector rod is fixed on the top plate below the lower die solid plate, and the upper end is located under the cavity. When the mold is opened, the upper template is opened, and the top plate goes further Push up to push the product out of the cavity. However, the ejector device with this structure has disadvantages. Some plastic products are cylindrical in appearance, and there must be no traces of ejector pins on the appearance, which cannot be satisfied by the ejection arrangement of ordinary molds. It is necessary to develop a slider ejection mold structure, so that it can be successfully self-mastered for injection molding production. To achieve smooth production of ordinary molds, it is necessary to set ejector pins on the outer surface of the product to eject the product. There will be traces of ejector pins on the outer surface of the product. Guilds are not accepted by customers and product end users.

Utility model content

The purpose of the utility model is to provide a mold with a slider ejection structure, which has the advantages of beautiful appearance, no thimble traces, smooth ejection of the mold, stable structure, mass production, and the smooth realization of self-parenting production. The ejection setting of the plastic mold will leave traces of ejector pins on the appearance of the product, which cannot be self-mastered.

In order to achieve the above object, the utility model provides the following technical solutions: a slider ejection structure mold, including a male mold and a female mold, a mold cavity is formed when the female mold and the male mold are closed, and the male mold is fixed with a second A slider insert, the master mold is provided with a second slider insert that cooperates with the first slider insert, the first slider insert is equipped with a slider seat, and the slider seat is fixed with The ejector rod, the first slider insert is provided with a through hole communicating with the cavity, the ejector rod is penetrated in the through hole, the slider seat is fixed with an oil cylinder seat, and the oil cylinder seat is fixedly connected to the oil cylinder, so A groove is arranged on the slider seat, a slider shovel base is connected to the groove, and a slider is arranged in the cavity.

Preferably, the upper end of the ejector rod is located on the lower surface of the product cavity of the mold, and the lower end of the ejector rod is located in the mold foot connected under the lower mold fixing plate.

Preferably, the 10mm insert of the second slider is still inside the product and cannot be pulled out when the mold is opened.

Preferably, the ejector rod is matched with a limiting groove provided in the female mold.

Preferably, after the injection molding of the product in the cavity of the male mold is completed, the manipulator takes the product away.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. The slider ejection mold structure of the utility model can realize smooth demoulding without any trace on the appearance of the product, and achieve the purpose of smooth automatic production.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a slider ejection structure mold, including a male mold 1 and a female mold 2, and a cavity 3 is formed when the female mold 2 and the male mold 1 are closed. A first slider insert 4 is fixed on the male mold 1, a second slider insert 5 cooperating with the first slider insert 4 is provided on the female mold 2, and the first slider insert 4 is equipped with a slider seat 6, the slider seat 6 is fixed with a push rod 7, the first slider insert 4 is provided with a through hole communicating with the cavity, and the push rod 7 is penetrated in the through hole, The slider seat 6 is fixed with an oil cylinder seat 8, and the oil cylinder seat 8 is fixedly connected to the oil cylinder 9. The slider seat 6 is provided with a groove, and the groove is connected with a slider shovel base 10. A slider 11 is arranged in the chamber 3 .

Working principle: when the mold is opened, the slider 11 moves outward relative to the injection molded product, and the ejector rod 7 on the slider seat 6 is always on the injection molded product, ensuring that the slider 11 will not affect the shape of the injection molded product when it moves outward relative to the injection molded product , when the slider 11 is completely separated from the injection molded product, the ejector pin 7 starts to separate from the injection molded product, the male and female molds are separated, all the sliders 11 are withdrawn, the second slider insert 5 is withdrawn, and the 10mm insert is still in the product The inside is not pulled out, and the ejector rod 7 ejects the cylinder base 8, the slider 11, the first slider insert 4 and the second slider insert 5 together, and the first slider insert 4 and the second slider insert 5 Drive the product to be ejected together, then the product will leave the cavity 3 of the male mold 1, and the manipulator will take the product away.
