Problems solved by technology
[0002] A mold is a device used to manufacture shaped objects. When the existing injection molding mold with internal threads is used, the surface of the processed product also has threads through the internal threads provided inside the mold. However, the product after injection is tightly connected to the inner wall of the mold. Fitting, and because of the existence of threads, it is inconvenient to take out the product. Therefore, we propose a mold for injection molded parts with internal threads and its demoulding method

The invention discloses an injection mold with an internal thread in the field of mold technology. Model blocks are inserted on both sides, a chute is provided on the outer wall of the top of the model block, two sets of connecting rods are arranged between the upper and lower inner walls of the slot, and the connecting rods are located in the inner cavity of the chute, the Blocks are provided on the left and right outer walls of the lower mold, and the outer walls on one side of the two groups of the blocks close to each other are respectively slidably connected with the left and right outer walls of the lower mold. The top of the stopper penetrates the casing, and the device moves the stopper downward from the outside of the model block, and resets by the reset spring, so that the moving block moves the model block to the outside with the model block, and the model block is removed from the inner cavity of the lower mold. The internal thread is not in contact with the product, so that the product can be easily removed from the lower die.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an injection molding mold with internal threads and a demoulding method thereof. Background technique [0002] A mold is a device used to manufacture shaped objects. When the existing injection molding mold with internal threads is used, the surface of the processed product also has threads through the internal threads provided inside the mold. However, the product after injection is tightly connected to the inner wall of the mold. Fitting, and the existence of threads makes it inconvenient to take out the product. Therefore, we propose an injection mold with internal threads and a demoulding method. Contents of the invention [0003] The object of the present invention is to provide an injection mold with internal thread and a demoulding method thereof, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object...
