Abstract

The invention belongs to the field of injection molds and in particular discloses an ejection mechanism for an engine flip injection mold. The ejection mechanism comprises a plurality of rotary shaftswhich are horizontally arranged and are arranged between a fixed mold and a base, wherein the rotary shafts are parallel to each other; one group of first cams are distributed on the rotary shafts; second cams are arranged between the adjacent first cams; air cylinders are arranged above the first cams and the second cams; cylinder bodies of the air cylinders are fixed on the lower surface of thefixed mold; piston rods of the air cylinders penetrate through piston plates and the cylinder bodies; the piston rods abut against the corresponding the cams respectively; resetting springs are arranged between the cylinder bodies of the air cylinders and the piston plates; the piston rods are provided with air inlet holes; the piston rods are provided with two inclined and upward air outlet holes in a directly facing manner; pipes are arranged in the piston rods and are used for communicating air outlet holes and the air inlet holes; gears which are mutually engaged are arranged at the leftends of the rotary shafts. The ejection mechanism for the engine flip injection mold, disclosed by the invention, aims at solving the sticking problem between an ejection rod and a product.

Description

technical field [0001] The invention belongs to the field of injection molds, and specifically discloses an ejection mechanism for an injection mold for an engine cover. Background technique [0002] Injection mold is a molding mold widely used in the production of plastic parts, and it is also a tool to give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a gating system and a cavity, and the hot-melted plastic is injected into the cavity through the gating system, and the required product is formed after cooling and molding. When th...
