Description

Technical Field

[0001] The present invention relates to the technical field of plastic product forming equipment, and particularly relates to a plastic forming production system and a processing method. Background Art

[0002] With the continuous development of the demand for plastic parts, the methods of plastic processing are also constantly updated. Injection molding is one of the main plastic forming processing methods; so-called injection molding is a plastic forming processing method in which thermoplastic plastics (PC, PE, PS, PP, PVC, PA, ABS, etc.) are plasticized in a barrel by external heating and the rotational shearing heat of a screw, and then injected into a mold with a cooling device at a certain injection pressure, and various plastic products are obtained after rapid cooling. However, for some products with high requirements, such as beverage bottles, water bottles, hanging bottles or medicine bottles, etc., it is difficult to meet the requirements by conventional injection molding. As the mainstream processing technology for plastic hollow containers, the "injection stretch blow molding" and "multi-layer co-extrusion" technologies have gradually become the focus of attention. So-called "injection stretch blow molding" is to inject the molten plastic injected by an injection machine into an injection mold, and form a transparent preform (also known as: preform) through rapid cooling. Then the preform is placed in a blow molding mold, the preform in the blow molding mold is heated to reach the blow molding temperature, compressed air is filled into the inner cavity of the preform, the preform is extended by a certain proportion, and after cooling, the required hollow product is obtained.

[0003] In the traditional "injection stretch blow molding" production process, the equipment for each link such as preform forming, handling, heating, blow molding, and blanking is often independent of each other, lacking effective coordination and cooperation. Under poor coherence, the production efficiency is low. For example, after the preform is formed by an injection machine, it needs to be transported manually or by a simple mechanical device, which is not only slow but also prone to inaccurate positioning problems, affecting the subsequent blow molding quality;

[0004] The existing mold clamping mechanisms used in the blow molding process all require a single drive source to control the movable mold clamping components. This method not only increases the cost and energy consumption of the equipment, makes the structure of the equipment complex, and has a large maintenance difficulty; when multi-station mold clamping processing is required, due to using a single drive source for drive control, it is difficult to ensure the synchronism and consistency of movement, affecting the synchronism of blow molding processing, the processing quality and production efficiency of products; and the existing blow molding process uses a handling manipulator for handling and blanking actions, but the existing handling and blanking methods have poor coherence. For example, after the blow molding is completed, the product in the mold needs to be first transported to a transfer device, and then the handling manipulator resets to the preform material outlet to transport the material into the blow molding device. The feeding and blanking cannot be completed synchronously, resulting in difficulties in the subsequent processing procedures and requiring manual intervention and adjustment, increasing the labor cost and production cycle and affecting the efficiency.
