[0001] The utility model relates to the technical field of multi-directional core pulling, and more specifically to a slider structure of multi-directional core pulling. Background Art
[0002] With the development of society and the advancement of science and technology, the scope and number of injection molding machines are becoming larger and larger, and people's lives are becoming more and more inseparable from the use of injection molding parts. During the injection molding process, the raw materials in a molten state enter the mold cavity through the nozzle, runner and gate, and are ejected through the mold opening after molding. Due to the complexity of the product structure, the features need to be cored out at the small holes of the product. However, the core-pulling structure in the prior art mostly uses a slider to drive the core to withdraw from the injection molding part to avoid adhesion of the injection molding part during ejection.
[0003] However, some mold products require large undercuts in multiple directions when demolding. Existing core pulling equipment can usually only perform core pulling and demolding operations in one direction, which has low work efficiency and large workload. On the other hand, the position of core pulling and demolding is small, and the required multi-directional core pulling operation cannot be completed. Therefore, a multi-directional core pulling slider structure is designed to solve the above problems. Utility Model Content
