Product ejection system

Abstract

The invention discloses a product ejection system which comprises a reset device used for enabling an ejector rod to be reset and an induction switch used for inducing reset of the ejector rod, wherein the induction switch sends a mold clamping starting signal to an injection molding machine controller when inducing that the reset device enables the ejector rod to be reset. According to the product ejection system, by implementing compulsory mechanical measures and using an electronic induction device on reset of an ejector pin board, the phenomenon that mold clamping cannot be carried out under the condition that the ejector pin board does not reset is ensured, thus absolute security of collision between the ejector pin and a sliding block is ensured. As for the mold after being improved by the product ejection system, the maintenance cost is lowered, the maintenance time is shortened, the cost is reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mold design, in particular to a product ejection system. Background technique [0002] In the mold, the product ejection system is very important, but in the actual mold, there will be problems of interference between the ejector pin and the slider or other devices. For example, when the thimble is under the slider, due to the different motion directions, mold collision occurs in actual production, which is a very serious problem in production. The maintenance cycle is long and the cost is high, which seriously affects the production of molds. [0003] For example, figure 1 It is a schematic diagram of the collision between the thimble and the slider when the mold is closed. Such as figure 1 As shown, the return of the ejector plate of the normal mold depends on the spring of the return rod, and there is no problem in the initial stage of the mold trial; when the product is mass-produced, the number of spring co...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the return of the ejector plate of the normal mold depends on the spring of the return rod, and there is no problem in the initial stage of the mold trial; when the product is mass-produced, the number of spring compressions increases, and it is in a fatigued state for a long time, and the ejector plate cannot return to its position. At this time, when the mold is closed, the side slider 2 is pushed forward, which will cause the slider to collide with the unreturned ejector pin 1, causing an accident and causing the ejector pin to break 3
