Injection mold lever double ejection mechanism

Abstract

The invention discloses a lever double-stripping mechanism of an injection molding mold. The mechanism comprises an upper compound plate and a lower compound plate of the mold, wherein the upper compound plate is connected with a mold cavity through a cushion block; a mold pin is arranged on the lower compound plate; an upper ejector pin plate and a lower ejector pin plate are arranged in the mold pin; the upper ejector pin plate is connected with a transmission rod; a supporting plate is arranged on the mold pin; a mold core fixing plate is arranged on the supporting plate; the mold core fixing plate is connected with a mold core; the transmission rod passes through the mold core fixing plate and is connected with a stripping plate; the mold core passes through the stripping plate, and amold cavity is formed between the mold core and the cavity; and a formed product is arranged in the mold cavity. The mechanism is characterized in that: a supporting block is arranged on the side wall of the cavity, the supporting block is connected with a lever through a pin, a convex rail is made at one end of the lever, a roller is arranged on the side wall of the mold core fixing plate, the roller is matched with the convex rail, and the other end of the lever extends into the cushion block and is connected with a mold cavity pressure plate; the mold cavity pressure plate is connected with a mold cavity pressure lever; and the mold cavity pressure lever extends into the mold cavity and is in contact with the product.

Description

technical field [0001] The invention relates to a lever double demoulding mechanism of an injection mold, which belongs to the field of plastic molds. Background technique [0002] Injection molds are used to produce plastic products, such as hollow barrel-shaped plastic products. The structure of traditional molds is usually to use the cavity to cover the outer wall of the product, and the core to pass through the product to form. The disadvantage is that the product often leaves when the mold is opened. In the cavity, but cannot ensure that the product stays on the core side, after the mold is opened, it cannot be ejected through the ejection system on the core side, causing the product to jam and cannot be ejected, and the mold fails, affecting production. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a method that utilizes the power of mold opening and closing, adopts the principle ...
