Technical Field
[0001] The utility model belongs to the technical field of injection molds, and relates to an injection mold for a one-out-of-two plastic cup tube blank. Background Art
[0002] An injection mold is a tool for producing plastic products and also a tool for endowing plastic products with a complete structure and precise dimensions. Injection molding is a processing method used in mass production of some parts with complex shapes. Specifically, it means that the heat-melted plastic is injected into the mold cavity by a high-pressure injection molding machine, and after cooling and solidification, the formed product is obtained. When the existing plastic cup tube blanks are injection-molded, due to the excessive length of the cup tube blanks, the mold is designed as a whole. However, when the injection molding is completed, the product parts are in a hot state, which will cause deformation or flanging of the product parts during part taking. Usually, when injecting trash cans, it is carried out singly, one bucket per process, which will waste working hours, increase the production time, and reduce the production efficiency. Therefore, an injection mold for a one-out-of-two plastic cup tube blank is proposed for the above problems. Content of the Utility Model

[0033] Furthermore, the lower insert core holes 601 and the upper insert core holes 501 are on the same center line. The lower mold core block 13 is inserted and slidably connected in the lower insert core holes 601, and the lower mold core block 13 corresponds to the upper mold core block 9.
[0034] The injection liquid can be injected into the interior of the lower mold core block 13 provided in the lower mold base 6 and the limiting plate 11 to form a mold.
[0035] Furthermore, two clamping parts 701 are opened in the middle part above the lower template 7, and the clamping parts 701 correspond to the lower mold core block 13. The bottom of the lower mold core block 13 is inserted and fixedly connected in the clamping parts 701.

A lower die base 6 is provided below the upper die base 5, and a lower die core block 13 is provided inside the lower die base 6. The bottom of the lower die core block 13 is fixed in the lower template 7 below the lower die base 6. During mold closing, the bottom of the upper die core block 9 is pressed against the top of the lower die core block 13, so that the two are internally connected, and the upper molding cavity portion 901 provided in the upper die core block 9 and the lower molding cavity portion 1301 provided in the lower die core block 13 are combined into a complete cavity. When the mold is opened, the upper die base 5 drives the upper die core block 9 inside and the structure above it to disengage from above the product part 14, so that the upper part of the product part 14 is exposed. Then the lower die base 6 disengages, so that the lower part of the product part 14 is placed inside the lower die core block 13, and the lower die core block 13 and the product part 14 are completely placed above the lower template 7. Subsequently, the product part 14 can be directly taken.
