Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with penetration and exhaust. Background Art

[0002] like Figure 1-4 As shown, it is an existing injection mold for producing an automobile control power supply housing, which includes a movable mold 1', a fixed mold 2' and an insert 5'. The opposite sides of the movable mold 1' and the fixed mold 2' are a movable mold cavity 3' and a fixed mold cavity 4' respectively. The movable mold cavity 3' and the fixed mold cavity 4' cooperate with each other to form a complete cavity. The automobile control power supply housing is formed in the cavity. There are multiple inserts 5', and the multiple inserts 5' are fixedly arranged on the movable mold cavity 3'. The automobile control power supply housing includes a rectangular shell 6' and a barrel portion 7' ​​protruding at one end of the rectangular shell 6'. The barrel portion 7' ​​is formed in a cavity formed between the multiple inserts 5'.
