[0004] The raw material enters the upper cavity and the lower cavity from the pouring port. After the raw material is cooled, the upper mold and the lower mold are separated, and then the pusher drives the side core puller to separate from the lower cavity, allowing the driving member to drive the driving rod to lift. At this time, the driving rod realizes the separation of the finished product from the lower cavity.

[0005] When the driving rod lifts the mold, the staff may mistakenly start the pusher, causing the pusher to drive the side core pull to abut against the driving rod, causing the side core pull or the driving rod to collide with each other, resulting in damage to the side core pull or the driving rod, thereby affecting the normal use of the injection mold. Summary of the invention

[0006] In order to improve the problem that the side core pulling and the driving rod are prone to collision with each other, the present application provides an injection mold.

[0008] By adopting the above technical solution, when the driving rod is not inserted into the lower cavity, the linkage assembly does not limit the movement of the accommodating bar, and the moving member drives the accommodating bar to move, so that the first sliding hole is located in the insertion path of the pushing member. At this time, the pushing member pushes the sliding bar to move, so that the sliding bar pushes the side core pull to insert into the lower cavity, so that the side core pull does not touch the driving rod, thereby avoiding the problem of the side core pull and the driving rod colliding with each other and being damaged; when the driving rod is inserted into the lower cavity, the linkage assembly limits the movement of the accommodating bar, and the moving member cannot drive the accommodating bar to move, and the second sliding hole is located in the insertion path of the pushing member. At this time, the pushing member is inserted into the second sliding hole, so that the pushing member does not abut the side core pull, making it difficult to insert the side core pull into the lower cavity, thereby avoiding the occurrence of mutual collision between the side core pull and the driving rod.
