Injection mold with good ejection effect

Abstract

The invention discloses an injection mold with a good ejection effect. The injection mold comprises an upper template and a lower template, wherein the upper template is fixedly installed on an upperbaseplate; a lower baseplate is disposed under the upper baseplate; a pair of mold pins is fixedly connected to the lower baseplate; the lower template is fixedly installed on upper ends of the mold pins; an embedded block is fixedly installed on the lower template; a mold cavity is formed at a joint between the embedded block and the upper template; an injection molding part is injected in the mold cavity; an ejection pin plate is installed between the mold pins on left and right sides in a slide manner; an ejection rod is in rotatable connection to the ejection pin plate; a wedged ejection block is in rotatable connection to the upper end of the ejection rod; and the wedged ejection block is installed inside an embedded block groove which is formed in the embedded block in a slide manner. The invention provides the injection mold with the good ejection effect, wherein the structure is rational; working principles are simple; working stability is high; and mold release is smooth.

[0002] With the continuous development of the economy and the continuous progress of society, it provides a wealth of material consumer goods, creating good conditions for improving people's living standards and pursuing personalized life, thus accelerating the demand for material consumer goods, and plastic products are many One of the material consumer goods, as we all know, the injection mold is a common mold used to form plastic products. Through the injection mold, a variety of plastic products can be formed to meet the various needs of people. After the products in the injection mold are formed , it is necessary to demould the product. The mold is widely used in the current industrial production, and usually includes a female mold and a male mold, and an ejection mechanism for ejecting the formed product. The ejection mechanism generally includes an ejector pin and a needle plate One end of the thimble passes through the movable mold to support the product located between the female mold and the male mold, and the other end is fixed on the needle plate. When demoulding, the ejector stick on the injection molding machine pushes the needle plate to drive the needle plate to move upward to lift the product. Now In the prior art, the thimble tends to stick to the injection molded part when ejecting the injection molded part, causing the injection molded part to be unable to be ejected smoothly
