Self-switching type bi-directional injection molding machine head

Abstract

The invention discloses a self-switching type bi-directional injection molding machine head, and belongs to the field of injection molding machine heads. The self-switching type bi-directional injection molding machine head comprises a first injection molding machine and a second injection molding machine. Ends of the first injection molding machine and the second injection molding machine are separately connected with a first auxiliary injection molding machine head and a second auxiliary injection molding machine head. A conveying pipeline is connected between the first auxiliary injection molding machine head and the second auxiliary injection molding machine head. A feeding pipe is connected to the middle of the end, away from the first injection molding machine, of the conveying pipeline. A main injection molding machine head is connected to the end, away from the conveying pipe, of the feeding pipe. The conveying pipe is connected with a pair of pneumatic butterfly valves. The pair of pneumatic butterfly valves are separately located on two sides of the feeding pipe. Through the bi-directional injection molding machine head, mixed injection molding is achieved, the mixing ratio of injection pigments is changed to obtain plastic products with more colors, and therefore types of injection molding materials purchased are decreased, the cost is lowered, and colors are of novelty.

Description

technical field [0001] The invention relates to the field of injection molding machine heads, and more specifically relates to a self-switching bidirectional injection molding machine head. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. The molding process of the general screw injection molding machine is: firstly, the granular or powdery plastic is added into the barrel, and the plastic is melted through the rotation of the screw and the outer wall of the barrel is heated, and then the machine is closed and the injection seat is moved forward. Make the nozzle ...

AI Technical Summary

Problems solved by technology

[0003] Existing injection molding machines are generally used alone, and the injection molding material of any color will be sprayed out through the injection molding head every time it is used. This requires the factory to purchase a large number of injection molding materials of different colors. The classification and storage of injection molding materials is a problem, and there are too many types of injection molding materials and it is easy to be confused. In addition, the color of the plastic products made of the injection molding materials provided is fixed before injection molding, and the factory cannot develop a new color number, which lacks novelty
