Abstract

The embodiment of the application discloses an injection mold, which belongs to the field of mold technology; it includes: a rear mold core; a front mold core, forming a mold cavity for a workpiece between the rear mold core; the front mold core has a first inclined hole, and the first inclined hole The first end of the hole is connected to the mold cavity, and the second end of the first inclined hole extends to the outer wall of the front mold core in a direction away from the rear mold core; the traction device is connected to the rear mold core; the front mold slope top passes through the first inclined hole, and the first end is located in the mold cavity, and the second end is connected to the traction device; the second end of the front mold slope top has a stroke in the first direction on the traction device, and the first end has a direction extending in the opposite direction of the first direction The forming part; wherein, the forming part is configured to form a forming hole of the workpiece when the mold is closed; the front mold core is configured to push the inclined top of the front mold to move along the first direction when the mold is opened, so that the forming part moves out of the forming hole. In the embodiment of the present application, the forming part can be moved out of the forming hole during the mold opening process, so that the demoulding of the workpiece is more convenient.

Description

technical field [0001] The present application relates to the field of mold technology, and in particular, to an injection mold. Background technique [0002] With the rapid development of the manufacturing industry, injection molding technology has been widely used in mobile terminals, household appliances, automobiles and other industries. In the existing injection molding process, molten plastic is first injected into the mold cavity, and after cooling and solidification, a workpiece of a specific shape can be formed, and then the workpiece is ejected by an ejector device. However, due to the unreasonable structural design of the mold in the related art, when molding some workpieces with forming holes, especially when the axial direction of the forming holes is not parallel to the mold opening direction, the workpiece is difficult to take out from the mold when the mold is opened. SUMMARY OF THE INVENTION [0003] The embodiment of the present application provides an i...
