Plastic mold internal screw thread floating stopping demolding mechanism

Abstract

Provided is a plastic mold internal screw thread floating stopping demolding mechanism. The mechanism comprises an upper doubling plate and a lower doubling plate. A fixed mold plate is arranged under the upper doubling plate. Support blocks are arranged on the lower doubling plate. A movable mold bottom plate, a lower gear fixing plate, an upper gear fixing plate, a transition gear fixing plate and a movable mold clamping plate are arranged on the support blocks. A movable platen is arranged on the movable mold clamping plate. There is a mold cavity between the movable platen and a fixed mold plate. A product is arranged in the mold cavity. Internal screw threads are arranged in the inner wall of the product. A screw thread core is arranged on the movable mold bottom plate. The head of the screw thread core is matched with the internal screw threads. The screw thread core is driven to rotate by power through a gear drive assembly. An upper top plate, a lower top plated and an ejector pin are arranged between the support blocks. The head of the ejector pin contacts a material handle after injection molding. A stopping insert block is arranged on the outer wall of the screw thread core. A stopping pin is arranged on the stopping insert block. The stopping insert block is embedded into the bottom of the wall body of the product. A floating spring is arranged on the movable mold clamping plate. A stop slot is arranged in the movable mold plate. A stop screw is arranged in the stop slot. The stop screw goes through the floating spring and is connected with the movable mold clamping plate.

Description

technical field [0001] The invention relates to a plastic mould's internal thread floating stop-rotation demoulding mechanism, which belongs to the field of plastic moulds, and is mainly used for processing internal thread caps, pipe fittings, collars and the like. Background technique [0002] At present, when plastic molds are used to produce internal thread caps, pipe fittings and collars, etc., the internal thread demoulding generally uses a hydraulic motor to drive the thread core to rotate and demould through gears, and then the product is ejected out of the mold by the mold ejection mechanism. , or take out the product manually. However, in actual production, when the threaded core is rotated for demoulding, the product is only attached to the fixed template, and there is no anti-rotation device. The product sometimes rotates with the threaded core, resulting in demoulding failure, affecting continuous processing, and even malfunctioning , causing losses. Contents ...
