Auxiliary demolding device for injection mold as well as operation method of auxiliary demolding device

Abstract

The invention discloses an auxiliary demolding device for an injection mold as well as an operation method of the auxiliary demolding device. The auxiliary demolding device comprises a base and a bearing frame; the base is fixedly mounted at one end of the bearing frame; brackets are vertically mounted on two sides of one end of the top of the base; an end part plate capable of moving up and downis mounted between the two brackets; a connecting plate is arranged on one side, close to the bearing frame, of the end part plate; a middle part plate is mounted on the middle part of one side, closeto the bearing frame, of the connecting plate; and screw rods are rotatably mounted between the two sides of the middle part plate and the two ends of the connecting plate. A third hydraulic column drives a pressing plate and an electromagnet plate on the end part of the pressing plate to abut against the exterior of a lower mold and then a fifth hydraulic pressing column drives a positioning plate to move downwards to press the bottom edge of the lower mold, so that the lower mold is more stable in a fixing frame and is insusceptible to waggle. A pull rope is shrunk and wound outside a winding shaft. The end part plate moves upwards to drive an upper mold to be separated from the lower mold, so that the mold is demolded safely and rapidly and is not liable to fall off, and damage to staff is avoided.

Description

Technical field [0001] The invention relates to an auxiliary demolding device, in particular to an auxiliary demolding device for an injection mold and an operation method thereof, and belongs to the application field of injection molds. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to the high-pressure injection of the plastic melted by heat into the mold cavity by the injection molding machine, and the molded product is obtained after cooling and solidification. [0003] When the upper and lower molds of the injection mold are demolded, external force is required for demolding. Workers often use hands to perform manual operations, the efficiency of demolding is low, and it is easy to cause danger to the staff. After the upper ...
