Description

Technical Field

[0001] This utility model relates to the field of valve body mold technology, and more specifically, to an injection molding mold for a lightweight valve body. Background Technology

[0002] Valve bodies, as parts used for pipe connections, are divided into metal valve bodies and plastic valve bodies. Plastic valve bodies are usually produced using injection molding, a molding method that combines injection and molding. Injection molding has many advantages, making it convenient to produce plastic valve bodies and increasing the efficiency and quality of valve body injection molding production. The valve body injection molding can be carried out using a lightweight plastic product injection mold disclosed in the prior art announcement number CN215882382U. The injection is performed through the injection tube into the lower mold. After injection molding, the motor is started, driving the first screw to rotate forward, causing the movable seat to move in the movable groove, which in turn moves the fixed frame and the lower mold. After the lower mold and the upper mold separate, the gear and rack mesh, and the lower mold continues to move, causing the gear and the second screw to rotate, which in turn drives the internal thread tube to move upward, so that the ejector block automatically ejects the plastic product from the lower mold. This allows for the automatic and rapid removal of the molded plastic product from the lower mold, facilitating rapid re-injection into the lower mold and improving the production efficiency of plastic products. The motor drives the first screw to rotate in reverse, causing the lower mold to move back to directly below the upper mold, so that it can be re-injected.

[0003] When the above-mentioned device is in use, it can automatically and quickly remove the valve body formed in the lower mold, which is conducive to rapid re-injection into the lower mold and improves the production efficiency of the valve body. However, it can only inject and mold flat workpieces. When the cooling jacket is displaced, it is easy to cause wear to the formed product, which can easily affect the quality of the product.
