Abstract

The invention relates to the field of plastic injection molding, in particular to an injection molding system and an injection molding method. The injection molding method comprises the steps that step 1. after plastic particles are added into a charging port, the plastic particles slide into a material melting pipe under the action of gravity; step 2. the plastic in the material melting pipe is heated, and the semi-molten plastic particles are downwards conveyed and stirred; step 3. the molten plastic is extruded into an upper mold and a lower mold; step 4. after the molten plastic is cooledand molded, a molded part is tightened to the lower end of the upper mold through a tightening circular ring; and step 5. after the lower mold moves downwards to the lowest position and drives the molded part to leave the upper mold, a suction pump stops, a tightening pipe continues to slide down to the position where the tightening pipe is matched with the lower mold; when the molded part moves down with the tightening circular ring to two guiding sliding columns, the molded part is blocked by grids of the two guiding sliding columns, stays on the two guiding sliding columns, and slantwise slides down along two the guiding sliding columns under the action of gravity, and thus, the separation of the molded part and the injection molding machine is completed.

Description

technical field [0001] The invention relates to the field of plastic injection molding, in particular to an injection molding system and an injection molding method. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is called beer machine in many factories, and injection molding products are called beer pieces. It is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products with plastic molding molds. Injection molding machine is the most used processing machinery in the plastic processing industry. Not only a large number of products can be directly produced by injection molding machine, but also the key equipment for forming injection stretch blowing process. The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw or the plunger to inject the plasticized plastic in th...
