Description

Technical Field

[0001] The utility model relates to the technical field of power supply shell injection molds, in particular to an exhaust structure of a power supply shell injection mold. Background Art

[0002] The power supply casing injection mold is a tool used to produce power supply casings. It heats and melts the plastic raw material and injects it into the mold. After cooling and solidification, it forms the required power supply casing shape. When using the power supply casing injection mold, regular inspection, cleaning and lubrication maintenance are required. Regularly check the various components of the mold and replace them in time if wear or damage is found. Clean the residual plastic in the mold to prevent scale from affecting product quality. Power supply casing injection molds are widely used in various electronic equipment, home appliances, communication equipment and other fields to produce power supply casings of various specifications and uses. Through reasonable design and careful manufacturing, power supply casing injection molds can produce high-quality power supply casings to meet various application requirements.

[0003] The production of power supply casings requires the use of injection molds. Although traditional injection molds have the ability to perform injection molding, they still have some shortcomings. For example, the positioning effect between the lower mold groove and the upper mold groove is not good, so it is easy for the lower mold groove and the upper mold groove to cause position offset after docking with each other, which will affect the injection molding quality. In addition, its exhaust effect is not good, so it is easy for injection molding defects to be caused by gas accumulation in the mold cavity or in the flow material, making it difficult to ensure the injection molding quality. Therefore, in response to the above problems, an exhaust structure for a power supply casing injection mold is proposed. Utility Model Content

[0025] See also Figure 1-8 , the utility model provides a technical solution:

[0026] A ventilation structure of an injection mold for a power supply casing includes a lower mold groove 1 and an upper mold groove 2. The bottom of the lower mold groove 1 is fixedly connected to a lower support plate 3, and the top of the upper mold groove 2 is fixedly connected to an upper support plate 4. A number of positioning components 5 are provided between the lower support plate 3 and the upper support plate 4. The tops of the front and rear walls of the lower mold groove 1 are both horizontally equidistantly arranged with a number of lower air holes 6. The bottoms of the front and rear walls of the upper mold groove 2 are both horizontally equidistantly arranged with a number of upper air holes 7, which are equal in number, corresponding in position and matching in specifications to the lower air holes 6. A protective component 8 is provided above the upper air hole 7.

[0027] The positioning assembly 5 includes a lower screw rod 501 fixedly connected to the four corners of the top of the lower support plate 3 and an upper screw rod 502 fixedly connected to the four corners of the bottom of the upper support plate 4 and corresponding to the position of the lower screw rod 501 and matching the specifications. A positioning slot 503 is opened at the top center of the lower screw 501, and a positioning block 504 corresponding to the position of the positioning slot 503 and matching the specifications is fixedly connected to the bottom center of the upper screw 502. A positioning screw sleeve 505 is provided on the outer side of the lower screw 501 and the positioning screw sleeve 505 is threadedly connected to the lower screw 501. The positioning assembly 5 can provide good positioning ability when the lower mold groove 1 and the upper mold groove 2 are closed to each other, so it is not easy for the lower mold groove 1 and the upper mold groove 2 to cause position deviation after docking with each other, thereby ensuring the quality of injection molding; the protective assembly 8 includes a connecting support plate 801 fixedly connected to the front wall and rear wall of the upper mold groove 2, and the connecting support plate 801 is equal in number and relatively positioned to the upper air hole 7 It should be provided that a connecting bolt 802 passes through the center of the connecting support plate 801 and connecting screw holes 803 corresponding to the position of the connecting bolt 802 are opened on the front and rear walls of the upper mold groove 2. A connecting belt 804 is provided at the bottom of the connecting support plate 801, and a protective plate 805 is provided at the bottom of the connecting belt 804. A protective plug 806 matching the specifications of the lower air hole 6 and the upper air hole 7 is fixedly connected to the protective plate 805 near the center of the upper mold groove 2. A number of positioning rods 807 are arranged at equal intervals on the outside of the protective plug 806. Positioning slots 808 corresponding to the position and specifications of the positioning rods 807 are provided below the lower air hole 6 and above the upper air hole 7. The protective component 8 can seal and protect the lower air hole 6 and the upper air hole 7 when not in use to prevent dust and impurities from entering the lower air hole 6 and the upper air hole 7 and entering the lower mold groove 1 and the upper mold groove 2 through the lower air hole 6 and the upper air hole 7, thereby preventing the entry of dust and impurities from affecting the injection molding quality.

[0028] Working process: The lower mold groove 1 and the upper mold groove 2 can be closed to form a complete injection cavity, thereby providing a basis for the injection molding of the power supply housing. The lower support plate 3 and the upper support plate 4 can provide installation space for the positioning component 5. The positioning component 5 can provide good positioning ability when the lower mold groove 1 and the upper mold groove 2 are closed to each other, so it is not easy for the lower mold groove 1 and the upper mold groove 2 to cause position deviation after docking with each other, thereby ensuring the injection molding quality. When the lower mold groove 1 and the upper mold groove 2 are docked with each other, first place the upper mold groove 2 on the top of the lower mold groove 1 and side The bottom end of the upper screw rod 502 will be aligned with the top end of the lower screw rod 501, and the positioning block 504 will be inserted into the positioning slot 503 to position the lower screw rod 501 and the upper screw rod 502. Finally, the positioning screw sleeve 505 is rotated to rotate the positioning screw sleeve 505 upward until it covers the connection between the lower screw rod 501 and the upper screw rod 502. The lower air hole 6 and the upper air hole 7 can form a complete exhaust hole when the lower mold groove 1 and the upper mold groove 2 are closed to each other, so that gas can be discharged through this exhaust hole. When the mold is opened, the structure of the vent hole affects the separation of the lower mold cavity 1 and the upper mold cavity 2. The protective component 8 can seal and protect the lower air hole 6 and the upper air hole 7 when not in use to prevent dust and impurities from entering the lower air hole 6 and the upper air hole 7 and entering the lower mold cavity 1 and the upper mold cavity 2 through the lower air hole 6 and the upper air hole 7, thereby preventing the entry of dust and impurities from affecting the injection quality. When the lower air hole 6 and the upper air hole 7 need to be protected, first move the protective plate 805 to the outside of the lower air hole 6 and the upper air hole 7 through the connecting belt 804, and then put the protective plug 806 is inserted into the lower air hole 6 and the upper air hole 7 to close the lower air hole 6 and the upper air hole 7. At the same time, the positioning rod 807 will be inserted into the corresponding positioning slot 808 for positioning to improve the connectivity between the protective plug 806 and the lower air hole 6 and the upper air hole 7, thereby preventing the protective plug 806 from falling off. Because the connecting support plate 801 is screwed into the connecting screw hole 803 through the connecting bolt 802 to be connected to the upper mold groove 2, when the protective component 8 is damaged, the protective component 8 can be disassembled by unscrewing the connecting bolt 802 for maintenance.
