Problems solved by technology

[0003] Invention application patent (application publication number: CN 106891492A) discloses an ejector device for a micro-injection molding machine, which does not require an independent driving force, and uses the relative movement of the non-moving part and the moving part during the mold opening process to push the thimble to make the product Ejection falls off; the ejection stroke of the thimble is completed by adjusting the length of the first bolt screwed to the front end of the ball screw, but because the first bolt is located inside, it is extremely inconvenient to adjust, which is not conducive to the ejection of the thimble stroke adjustment

Abstract

The invention discloses an ejection device for an injection mold. The ejection device comprises a rack, a movable mold and an ejection device body. The rack is arranged at the left side of the movablemold, and the movable mold can achieve leftward and rightward translation relative to the rack. The movable mold is provided with multiple ejection passing holes, wherein the multiple ejection passing holes are through in the left-right direction and each internally provided with a right ejection rod in an elastic manner. An ejection adjustment support seat is formed on the right end face of therack. The ejection device body comprises multiple left ejection rods, wherein the multiple left ejection rods are arranged on the rack and the ejection adjustment support seat in a manner that the left ejection rods are synchronously adjusted in the left-right direction. The right ends of the left ejection rods can be arranged in the ejection passing holes in an inserted manner. By means of the ejection device, the ejection strokes of the right ejection rods can be controlled by adjusting the left-right positions of the left ejection rods, and thus, the right ejection rods can be prevented from being ejected into an inner chamber of a stationary mold; and meanwhile, the ejection position of each workpiece can be adjusted, and the subsequent procedures can be implemented conveniently.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an ejection device for injection molds. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Invention application patent (application publication number: CN 106891492A) discloses an ejector device for a micro-injection molding machine, which does not require an independent driving force, and uses the relative movement of the non-moving part and the moving part during the mold opening process to push the thimble to make the product Eje...
