Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a glue feeding mechanism for solving the problem of limited mold opening stroke of a machine. Background Art

[0002] The traditional mold structure generally uses a three-plate mold demolding method, which has a large mold opening stroke and a long mold opening cycle. The most important thing is that it cannot meet the needs of the injection molding machines used by customers for production. In addition, the sprue and products need to be taken out manually, which lengthens the production cycle and reduces efficiency. With the rising labor costs today, the cost is increased invisibly. Therefore, customers cannot accept the three-plate mold. Utility Model Content
