Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-4, the utility model provides an injection mold structure, which comprises a lower module 1 and an upper module 2 pressed on the upper end surface of the lower module 1, wherein the upper end surface of the lower module 1 is provided with a lower mold core 3 embedded and assembled inside, the upper module 2 is provided with an upper mold core 4 embedded and assembled inside and pressed with the lower mold core 3, the contact surface of the lower mold core 3 and the upper mold core 4 is provided with a hollowed forming cavity 5, during assembly, the upper module 2 is provided with an upper mold plate 9 connected to the top for synchronously controlling the movement of the upper mold core 2, the bottom of the lower module 1 is provided with a fixed lower mold plate 10, the top of the upper mold plate 9 is provided with a connecting piece for connecting and controlling the movement, all are connected through an integrated structure, as the upper module 2 approaches to the lower module 1 until the upper mold core is pressed, the upper mold core 4 and the lower mold core 3 corresponding inside are combined to form an injection molding space forming cavity 5, and after liquid is injected into the forming cavity 5 through a top liquid injection port 11 and cooled, so as to obtain an injection molded product.
