Description

Injection molding machine system for automotive bumper molding

technical field

The invention is applied to the background of automatic injection molding processing, and the name is an injection molding machine system for processing and molding automobile bumpers.

Background technique

The car bumper is an important part of the appearance of the car and the main decorative part of the car exterior. Car bumpers are now mainly plastic bumpers, which have certain strength, rigidity and decoration. It is integrated with the body and plays a very good decorative role, becoming an indispensable and important part of the appearance of the car.

Most of the current plastic bumpers are injection molded by injection molding machines, which are also known as injection molding machines or injection machines. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, make it inject and fill the mold cavity, and automate the injection molding process. However, the existing automobile bumper injection molding machines have many limitations, such as:

1. Due to the large overall volume of the automobile bumper, the amount of injection particles required for a single injection is relatively large. However, most injection molding machines rely on manual feeding, and single feeding is limited, requiring workers to constantly Adding materials is inconvenient and increases the fatigue strength of workers.

2. At present, the feeding port of most injection molding machines is set on the uppermost side of the injection molding machine. Workers need to climb to a high place every time they feed, and pour the injection molding particles into the feeding funnel. The operation is troublesome and dangerous.

3. The number of injection molding particles required for one-time injection molding of automobile bumpers is large, and they are easy to accumulate after feeding, resulting in blockage of the feeding port.

4. Due to the large number of injection molding particles, it takes a long time to heat and plasticize them, the injection molding efficiency is low, and it is easy to cause uneven plasticization, and some plasticization is overheated, resulting in Burnt, unable to perform normal injection molding operations.

5. It is necessary to ensure the dryness of the injection molding particles before injection molding. The damp particles will affect the texture and quality of the bumper during injection molding.

6. When demoulding the automobile bumper, due to the large overall volume, it is often necessary for the staff to manually demould, which is inconvenient and has a low degree of automation.

Therefore, it is necessary to provide an injection molding machine system for automobile bumper processing and molding, which can achieve the effect of automatic injection molding processing.
