Injection molding process of combined isolation guardrail

Abstract

The invention relates to an injection molding process of a combined isolation guardrail, and relates to the technical field of injection molding processes. The injection molding process comprises the steps of filling, cutting, pressure maintaining, cooling and demolding. The filling is divided into high-speed filling and low-speed filling, the shearing rate of the high-speed filling is high, but the cooling of a thin wall is not obvious, the shearing rate of the low-speed filling is low, but curing is thick, the cutting is divided into linear cutting and bent wire cutting, and the linear cutting is used for cutting redundant materials extruded by the die. By means of linear cutting and bent line cutting, redundant materials on the mold can be scraped off. According to a numerical control device arranged on the device, the die can be subjected to cold pressing, and meanwhile, a bent surface can be formed by cutting the mold through a bent line cutter, so that the practicability is high, the mold can be pressurized by arranging a pressurizer, so that forming of the die is accelerated, and therefore, the rigidity and hardness of the guardrail in the mold are effectively improved, and a situation that the guardrail is fractured and falls off after being used is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding technology, and in particular relates to an injection molding technology of a combined isolation guardrail. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. [0003] However, some existing injection-molded isolation guardrails are more upright and inconvenient to assemble. In addition, the cooling speed of some devices is too slow, resulting in t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide one, one of which is to solve some injection-molded isolation guardrails, which are relatively upright and inconvenient to assemble, and the cooling speed of some devices is too slow, so that Causes the external cooling of the material in the mold, the phenomenon that the internal has not been cooled, resulting in insufficient internal hardness and rigidity, resulting in cracks after use
