Automatic cleaning device for blow molding mold for plastic product processing

Abstract

The invention discloses an automatic cleaning device for a blow molding mold for plastic product processing, and relates to the technical field of blow molding machines. The problems that in use of anexisting blow molding device, certain residues are left on a mold parting surface after blow molding is completed, and the residues may enter a plastic product in next use, so that the quality problem is caused, and then economic losses are caused are solved. The automatic cleaning device comprises a blow molding machine main body; the top of the blow molding machine main body is slidably connected with a front-back sliding seat; the left side and the right side of the front-back sliding seat are each fixedly connected with a mold closing driving member; cleaning connecting rods are connectedto the left side and the right side of the middle of the blow molding machine main body; and cleaning plates are mounted on the side surfaces of the cleaning connecting rods. According to the automatic cleaning device, unfolding of the cleaning plates is achieved through a mold opening action, good cleaning on a mold is achieved, residues are prevented from influencing next machining, the machining precision is improved, meanwhile, the cleaning plates are high in folding rate and small in occupied space after being folded, production cannot be influenced, and good practicability and economiceffects are achieved.

Description

technical field [0001] The invention relates to the technical field of blow molding machines, in particular to an automatic cleaning device for blow molding molds used for processing plastic products. Background technique [0002] Blow molding is a method for processing hollow containers such as bottles. First extrude or inject the thermoplastic resin, preform into a tubular parison, then put it into the metal cavity and blow it to make it stick to the inner wall of the cavity, cool and solidify, and the mold needs to be extruded during the blow molding process. Sliding back and forth between the pressing process and the blowing process. [0003] For example application number: CN201680015206.9 provides a kind of blow molding device (1), and it has: mold (11), wherein is provided with preform (2); Cylindrical nozzle (15), inserts preform from lower end side ( In the mouth part (3) of 2), the pressurized fluid supply part (18) supplies pressurized incompressible fluid to th...
