Description

Technical Field

[0001] This utility model relates to the field of molds, specifically to an injection mold extension ejection and transfer device. Background Technology

[0002] Plastic molds are tools used in the plastics processing industry, working in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastic types and processing methods, and the varying complexity of plastic molding machines and plastic products, plastic molds also come in a wide variety of types and structures.

[0003] The "Extended Ejection Mechanism for Injection Molds" disclosed in application number "CN202123022312.7" is also an increasingly mature technology. This utility model relates to the field of injection mold technology, specifically to an extended ejection mechanism for injection molds, including a support tube. A steel collar is slidably fitted onto the surface of the support tube, and four fixing blocks are fixedly connected to the outer surface of the steel collar. This extended ejection mechanism uses a mechanism on the four fixing blocks, which can be driven by a hydraulic cylinder, to clamp the mold box. The hydraulic cylinder pulls the mold box down, causing it to descend vertically along the support tube. The molded workpiece, after internal cooling, then protrudes to the outside, achieving demolding. This solves the problem that in existing injection molds, after internal injection molding, the molded workpiece needs to be pre-cooled before demolding, often requiring manual demolding by operators, which is extremely cumbersome. Furthermore, traditional extended ejection mechanisms cannot be adjusted for mold boxes of different sizes, hindering convenient demolding.

[0004] Traditional injection molds have low extension and ejection transfer efficiency. The transfer effect is generally characterized by low transfer efficiency, which is not efficient and fast enough. This can easily lead to poor stability in the extension efficiency of the injection mold and make it difficult for subsequent ejection transfer to achieve better transfer and poor opening effect.
