Ejection and control device for injection product of mold injection machine

Abstract

The invention relates to a component structure device, in particular to an ejection and control device for injection products of a mold injection machine. The device comprises an oil cylinder, a cylinder piston rod, a metal ejection plate for a mold, an ejection rod and an ejection hole, wherein the ejection hole is arranged in a movable mold, and one end of the ejection rod is fixedly connected with the metal ejection plate for a mold while the, the other end thereof is inserted in the ejection hole. The invention is characterized in that the device is provided with an electromagnet; one end of an iron core rod of the electromagnet is fixedly connected with the cylinder piton rod while the other end thereof is opposite to the metal ejection plate. A mold injection machine with the ejection and control device for injection products has the characteristics that the ejection is smooth, the ejection can return in place, and the installation height of a mold is lowered. Compared with the prior art, the invention has the advantages of low mold manufacture cost, no blocking during the injection, and the like, and is capable of being conveniently installed on the ejection system of any mold injection machine.

Description

technical field [0001] The invention relates to a component structure device on an injection molding machine, in particular to an injection molding product ejection control device used on an injection molding machine. Background technique [0002] Each injection molding cycle of the injection molding machine includes four steps: mold clamping, injection, cooling, and mold opening. After the injection molding machine opens the mold, the injection molded product must be taken out from the mold cavity. At present, the injection molding machine uses the ejection control device to eject the injection molded product from the mold cavity. The existing ejection control device (such as figure 1 Shown) includes oil cylinder 13, oil cylinder piston rod 12, mold metal ejector plate 15, return spring 17, ejector rod 16, ejector hole 18, wherein ejector hole 18 is arranged on movable mold 8, ejector rod 16 one end and The mold metal ejector plate 15 is fixedly connected, the other end is...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the use of spring return, the force is not uniform, and it is easy to cause the mold metal to be stuck out of the plate;

[0004] 2. Since the height of the mold is limited by the return spring, the spring is too long and the elasticity is insufficient, and the mold often cannot return to its position. When the injection molding machine closes the mold, it is easy to damage the mold;

[0005] 3. The working efficiency of the injection molding machine is restricted, and the mold manufacturing cost is high

In recent years, there are various styles of products molded by injection molding machines, especially the heights of plastic molds vary greatly, and the effective opening stroke of a certain type of injection molding machine is constant, so it restricts the working efficiency of the injection molding machine and also Increased mold manufacturing costs

[0006] 4. The injection molding machine cannot perform injection molding on slender products

For slender products, due to the need for higher molds, which cannot be installed on the injection molding machine, the injection molding machine cannot perform injection molding on slender products
