Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, and in particular to a plastic shell molding mold. Background Art

[0002] A mold is a tool used to manufacture products, usually made of materials such as metal or plastic. Molds can be divided into different types such as injection molds, die-casting molds, stamping molds, casting molds, etc., which are used to manufacture products of different materials and shapes. The manufacture of molds requires multiple links such as design, processing, and assembly to ensure the quality and precision of the final product. Molds play an important role in industrial production, which can improve production efficiency, reduce costs, and produce large quantities of high-quality products.

[0003] However, in the process of using molds for production and processing, the processing materials often stick to the mold. If the materials cannot be removed in time during production, the mold may be damaged, and the mold surface may be worn, scratched or cracked. If the mold is seriously damaged, it may be necessary to repair or replace the mold, increasing production costs. Failure to remove the materials may also cause defects in the plastic shell, such as rough surface, deformation, cracks, etc. These defects may affect the appearance and performance of the product and reduce product quality. Failure to remove the materials will require more time and effort to remove the plastic shell from the mold, which will reduce production efficiency and increase production costs.

[0004] Therefore, there is an urgent need for a plastic shell molding die to solve the above problems. Utility Model Content

[0005] The utility model provides a plastic shell forming mold, which solves the problem in the related art that failure to remove the material in time during production may cause damage to the mold, failure to remove the material may also cause defects in the plastic shell, and more time and effort are needed to remove the plastic shell from the mold, which will reduce production efficiency and increase production costs.

[0006] The technical solution of the utility model is as follows: a plastic shell molding mold, comprising a bottom plate, a lower mold is fixedly connected to the top of the bottom plate, an upper mold is arranged on the top of the lower mold, a molding cavity is opened on the top of the lower mold, a movable groove is opened at the bottom of the upper mold, a movable block is slidably connected to the inner wall of the movable groove, a molding pressure block is fixedly connected to the bottom of the movable block, the molding pressure block is adapted to the movable block, four symmetrically distributed springs are fixedly connected to the top of the movable block, the top of the spring is fixedly connected to the top of the movable groove, an injection hole is opened on one side of the lower mold, the injection hole is connected to the molding cavity, and a water inlet hole and a water outlet hole are respectively arranged on both sides of the lower mold.

[0007] Preferably, positioning protrusions are provided at the four corners of the top of the lower mold, and positioning grooves are provided at the four corners of the bottom of the upper mold, and the positioning protrusions are matched with the positioning grooves.

[0008] Preferably, the bottoms of both sides of the lower mold are fixedly connected with mounting blocks, and both sides of the upper mold are fixedly connected with threaded connection blocks, the inner cavity of the threaded connection block is threadedly connected with a threaded rod, and the bottom end of the threaded rod is rotatably connected to the mounting block.

[0009] Preferably, the movable block is fixedly connected with limiting blocks on all sides, the inner wall of the movable groove is provided with limiting grooves, and the limiting blocks are slidably connected to the inner wall of the limiting groove.

[0010] Preferably, a cooling pipe is provided inside the lower mold, one end of the cooling pipe is connected to the water inlet, and one end of the cooling pipe away from the water inlet is connected to the water outlet.

[0011] Preferably, the cooling pipe is a continuously arranged U-shaped bend pipe.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. In the utility model: when the utility model is used, the user injects material into the molding cavity through the injection hole, and then rotates the threaded rod. The rotation of the threaded rod drives the threaded connection block to move up and down through the threaded connection. The movement of the threaded connection block drives the upper mold and the molding block to move synchronously. When the upper mold moves downward and contacts the lower mold, the molding block is squeezed and moves upward. The movement of the molding block drives the movable block to move upward. The spring is squeezed and compressed to generate elastic force. After the stamping is completed, the user can input coolant into the cooling pipe through the water inlet hole to speed up the cooling and molding speed of the material. After the material is cooled and formed, the upper mold moves upward. When the upper mold moves upward, the spring rebounds, thereby pushing the movable block and the molding block to move downward, thereby pushing the material to separate it, avoiding the adhesion of the material to the molding block, thereby reducing the production efficiency.

[0014] 2. The utility model has the advantage of being able to effectively remove production materials and prevent adhesion during production. Through the coordinated use of the molding block, the injection hole, and the molding cavity, the material is injected into the molding cavity and processed into a mold. Through the coordinated use of the upper mold, the movable block and the molding block, during stamping production, the movable block and the molding block will move upward and apply pressure to the spring. Through the setting of the spring, when the upper mold moves upward after stamping, the spring will rebound and push the movable block and the molding block to move downward, thereby pushing the adhered material out of the way, ultimately achieving the purpose of separating the adhered material and avoiding the problem of reduced production efficiency caused by material adhesion.

[0015] 3. In the utility model: through the coordinated use of the positioning protrusion and the positioning groove, the lower mold and the upper mold are positioned, avoiding the problem that the lower mold and the upper mold cannot be quickly positioned during use; through the setting of the mounting block, the threaded connection block and the threaded rod, the upper mold is guided, avoiding the problem of misalignment of the upper mold during movement; through the setting of the limit block and the limit groove, the movable block is limited and guided, avoiding the problem of the movable block falling or tilting during movement; through the setting of the cooling pipe, the cooling and molding speed of the material is improved, avoiding the slow cooling and molding speed of the material, thereby affecting the production efficiency; through the curved setting, the residence time of the coolant inside the cooling pipe can be increased, effectively improving the cooling efficiency.
