Rapid blow molding device for milk bottles

Abstract

The invention relates to the technical field of milk bottle processing, and discloses a rapid blow molding device for milk bottles. The rapid blow molding device comprises a fixed bottom plate, supporting frames are mounted on the two sides of the upper end of the fixed bottom plate, a top plate is mounted at the top ends of the supporting frames, a telescopic column is mounted in the middle of the lower end of the top plate, a fixed cylinder is mounted at the bottom end of the telescopic column, an inclined round block is rotationally arranged inside the fixed cylinder, guide pipes are mounted at the lower sides of the two ends of the fixed cylinder, the guide pipe on the left side is connected with an injection molding mechanism through a liquid inlet pipe, the guide pipe on the right side is connected with an air injection mechanism through a high-pressure pipe, a nozzle is mounted at the bottom end of the fixed cylinder, a driving roller is mounted in the middle of the supporting frame on the left side, a driven roller is mounted in the middle of the supporting frame on the right side, and a conveying belt is mounted on the outer side between the driving roller and the driven roller. The rapid blow molding device for the milk bottles realizes intermittent conveying of blow molding molds, thus the need of large-scale production of the milk plastic bottles is met, meanwhile,the fixed cylinder and the inclined round block are arranged to switch the injection molding mechanism and the air injection mechanism, and the blow molding effect is further improved.

Description

technical field [0001] The invention relates to the technical field of milk bottle processing, in particular to a rapid blow molding device for milk bottles. Background technique [0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. It is mainly to place the tubular plastic parison obtained by extrusion or injection molding of thermoplastic materials into a split mold while it is hot or heated to a softened state. After the mold is closed, compressed air is injected into the parison immediately to make the plastic parison inflate and cling to the inner wall of the mold. After cooling and demoulding, various hollow products can be obtained, which are widely used in the production of plastic milk bottles. According to The parison production method, blow molding can be divided into extrusion blow molding and injection blow molding, and the newly developed multi-layer blow molding and stretch blow molding.

Problems solved by technology

[0004] Chinese patent (notification number: CN209775526U) discloses a blow molding machine for producing plastic milk bottles with uniform cooling, including a base, and vertical brackets are installed on the left and right ends of the base, between the left and right two brackets. A mounting seat is provided, one side of the mounting seat is affixed to one of the brackets, the other side of the mounting seat is affixed with a fixed blank mold, and one side of the fixed blank mold is provided with the A mobile blank mold that is compatible with the fixed blank mold, the mobile blank mold is installed on the other support through a telescopic electric cylinder, and both the mobile blank mold and the fixed blank mold are provided with blank mold cavities, although the The device can quickly form plastic milk bottles to a certain extent, but in actual operation, the processing efficiency of the device is very low, and it cannot meet the needs of large-scale molding. At the same time, two tubes are used for feeding and blowing in the blow molding process. Road, easy to form defective products, therefore, need further improvement
