Problems solved by technology

[0003] The existing blow molding equipment is a symmetrical closed pressure device. This device can ensure the pressure during blow molding and the shape after blow molding. However, after the blow molding work is completed, the end of the plastic product is affected by the hot air flow. It is completely solidified, so the port part of the plastic product is caused to shrink. The prior art adopts the method of manual construction for processing, but this processing method has certain errors and is relatively slow. Therefore, a plastic product is blown with corrected flash Equipment came into being

Abstract

The invention relates to the technical field of plastic product blow molding, and discloses burr correction blow molding equipment for plastic products. The equipment comprises a shell. The two side walls in the shell are movably connected with screws. The bottoms of the screws are movably connected with cams. The surfaces of the cams are movably connected with clamp plates. A sliding rail is formed at the bottom of the shell. The surface of the sliding rail is in sliding connection with a connecting block. The tops of the screws are movably connected with winding shafts. Pull ropes are woundon the surfaces of the winding shafts. The other ends of the pull ropes are movably connected with compression springs. The backs of the compression springs are movably connected with sliding grooves.The surfaces of the compression springs are movably connected with scraping knives. The two sides of each scraping knife are movably connected with guide wheels. The sides, away from the scraping knives, of the guide wheels are movably connected with spring rods. The left side and the right side of the shell get away from each other, the compression springs lose pulling force so as to release theforce that the compression springs are compressed previously, and therefore the scraping knives are pushed out, and the effect that burrs are corrected through the work track of pressurization equipment after blow molding is finished is achieved.

Description

technical field [0001] The invention relates to the technical field of blow molding of plastic products, in particular to a flash blow molding equipment for plastic products. Background technique [0002] Also known as hollow blow molding, a rapidly developing plastic processing method, blow molding can be divided into extrusion blow molding and injection blow molding according to the parison production method, and the newly developed multi-layer blow molding and stretch blow molding; The working process of blow molding is: place the tubular plastic parison in the split mold while it is hot, and immediately inject compressed air into the parison after the mold is closed, so that the plastic parison is inflated and clings to the inner wall of the mold. After cooling and demolding, various hollow products can be obtained. [0003] The existing blow molding equipment is a symmetrical closed pressure device. This device can ensure the pressure during blow molding and the shape ...
