Embodiment Construction

[0022] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present invention, and other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention.

[0023] A method for blister forming, comprising the steps of:

[0024] S1. Start the heating system to heat the upper and lower molds, and adjust the temperature of the upper and lower molds through the temperature control system. According to the specifications of the workpiece, the temperature is controlled between 85 and 200 degrees;

[0025] S2. Place the workpiece in the lower mold and preheat it;

[0026] S3. Turn on the vacuum suction device, and vacuum-form the preheated workpiece downward.

[0027] Such as figure 1 The blister forming machine provided by the present invention in...

Abstract

The invention discloses a plastics sucking molding machine and a plastics sucking molding method. The plastics sucking molding machine comprises a rack, an upper mold, a lower mold, a heating system and a control device. The upper mold is a movable mold. Driven by a lifting device, the upper mold can be in buckled sealing with the lower mold. The cavity wall of the upper mold is a hollow structure. The heating system heats an upper end face of a workpiece inside the mold through heat conduction to the cavity wall of the upper mold. The lower mold is a positioning mold, and the cavity wall of the lower mold is a hollow structure. The inner cavity wall of the lower mold is provided with multiple through holes. The heating system heats a lower end face of the workpiece inside the mold through heat conduction to the cavity wall of the lower mold. A vacuum suction device can generate vacuum suction to the lower end face of the workpiece through the multiple through holes of the lower mold. The plastics sucking molding machine and the plastics sucking molding method provided by the invention have advantages of low energy consumption, high heat conduction efficiency, attractive and unified appearance of finished products and the like.

Description

technical field [0001] The invention relates to a plastic molding device and a molding method, in particular to a plastic suction molding machine and a plastic suction molding method. Background technique [0002] Blister machine is to heat and plasticize pvc , PE , PP , PET , HIPS It is a machine that absorbs thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. The traditional blister process uses a single-sided mold to heat the material, and then uses vacuum suction to soften the heated PVC, PET, etc. thermoplastic sheet through mold Blister into various shapes of blister trays, blisters, etc. The traditional single-sided heating only heats one side of the workpiece, which will cause the temperature of the two sides of the workpiece to be inconsistent. During processing, there may be problems such as incomplete shape of the workpiece and many defects. Moreover, the heating of the blister machine is now ...
