Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a charger housing. Background Technology

[0002] The charger casing injection mold can realize the injection molding of the charger casing, and the charger casing can be mass-produced.

[0003] The patent announcement number CN220841225U discloses an injection mold for a charger housing, including an upper mold, a lower mold installed below the upper mold, and mold fixing components arranged around the upper and lower molds. The lower mold has a demolding ejection assembly installed inside, and the upper mold has a cavity support assembly installed inside. The upper mold has mold closing positioning holes at its four corners, and mold closing positioning rods fixed to the top four corners of the lower mold are inserted inside the mold closing positioning holes. The demolding ejection assembly includes an ejection base installed in the center of the lower mold, and a nut is embedded in the bottom of the ejection base. The aforementioned demolding and ejection assembly, after rotating the handle, allows the ejection base to rise uniformly within the guide groove on the lower mold, thus ejecting the formed charger housing upwards. This ensures uniform force on the charger housing and enables quick and safe demolding. However, during demolding, sliding friction occurs between the ejection base and the lower mold, leading to wear on both after prolonged use. This results in a large gap between the ejection base and the lower mold, causing overflow during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a charger housing injection mold that reduces friction and prevents gaps from increasing due to friction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a charger housing injection mold, comprising a concave mold and a convex mold, wherein a tapered groove is provided on one side wall of the concave mold and a tapered top block is provided on one side of the tapered groove, and a cavity is provided on one side of the concave mold and an ejection drive assembly is provided in the cavity.

[0006] Preferably, the ejection drive assembly includes a connecting plate disposed within the cavity, with a spring disposed on one side of the connecting plate and an ejector rod disposed on the other side of the connecting plate, one end of the ejector rod penetrating the die and extending to one side of the die, a connecting rod fixedly connected to one side wall of the connecting plate, and one end of the connecting rod penetrating the die and fixedly connected to the conical ejector block.

[0007] Preferably, a base plate is fixedly connected to one side wall of the cavity, and an adjusting bolt is threadedly connected to one side wall of the base plate. One end of the adjusting bolt passes through the base plate and extends into the cavity. A fixing plate is provided on one side of the adjusting bolt inside the cavity, and one side wall of the fixing plate is fixedly connected to a spring.

[0008] Preferably, a limiting slide rod is fixedly connected to the inner wall of the cavity, and the limiting slide rod passes through the connecting plate.

[0009] Preferably, the conical top block is made of cemented carbide.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention, by using a conical groove and a conical top block in conjunction, allows the conical top block to fill the conical groove during use. During demolding, the ejection drive assembly can push the conical top block, enabling it to push the injection-molded product and complete demolding. When pushing the conical top block, it only needs to move a small position to disengage from the conical groove. As the conical top block continues to move, it will not rub against the inner wall of the conical groove, thus preventing the gap between the conical groove and the conical top block from increasing due to friction. Therefore, even after long-term use, this device is less prone to overflow. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figures 1-4A charger housing injection mold includes a concave mold 1 and a convex mold 2. A tapered groove 3 is provided on one side wall of the concave mold 1, and a tapered top block 4 is provided on one side of the tapered groove 3. A cavity 5 is provided on one side of the concave mold 1, and an ejection drive assembly is provided in the cavity 5.

[0015] As can be seen from the above structure, by setting the conical groove 3 and the conical top block 4 to work together, the conical top block 4 can fill the conical groove 3 during use; during demolding, the ejection drive component can push the conical top block 4, so that the conical top block 4 can push the injection-molded product, thereby completing the demolding. When pushing the conical top block 4, the conical top block 4 only needs to move a little position, and the conical top block 4 will disengage from the conical groove 3. When the conical top block 4 continues to move, the conical top block 4 will not rub against the inner wall of the conical groove 3, so that the gap between the conical groove 3 and the conical top block 4 will not increase due to friction. Thus, the device is not prone to overflow during long-term use.

[0016] Furthermore, the ejection drive assembly includes a connecting plate 6 disposed within the cavity 5, with a spring 7 on one side of the connecting plate 6 and an ejector rod 8 on the other side. One end of the ejector rod 8 penetrates the cavity 1 and extends to one side of the cavity 1. A connecting rod 9 is fixedly connected to one side wall of the connecting plate 6, with one end of the connecting rod 9 penetrating the cavity 1 and fixedly connected to the conical ejector block 4. By using the connecting plate 6 and spring 7 in conjunction, when the cavity 1 and the punch 2 are closed, the punch 2 can press the ejector rod 8, thereby causing the ejector rod 8 to move the connecting plate 6. The moving connecting plate 6 causes the connecting rod 9 and the conical ejector block 4 to move, so that the conical ejector block 4 is received into the conical groove 3, while simultaneously storing force for the spring 7. When the cavity 1 and the punch 2 are separated, the spring 7 can push the connecting plate 6, the connecting rod 9, and the conical ejector block 4, thereby causing the conical ejector block 4 to eject the injection-molded product.

[0017] Furthermore, a base plate 10 is fixedly connected to one side wall of the die 1, and an adjusting bolt 11 is threadedly connected to one side wall of the base plate 10. One end of the adjusting bolt 11 passes through the base plate 10 and extends into the cavity 5. A fixing plate 12 is provided on one side of the adjusting bolt 11 located inside the cavity 5, and one side wall of the fixing plate 12 is fixedly connected to the spring 7. By setting the adjusting bolt 11 and the fixing plate 12 to work together, after the spring 7 has reduced force due to long-term use, the adjusting bolt 11 can be rotated to push the fixing plate 12, thereby causing the fixing plate 12 to compress the spring 7, so as to restore the force of the spring 7 and ensure that the force of the spring 7 can push the conical top block 4, etc.

[0018] Furthermore, a limiting slide rod 13 is fixedly connected to the inner wall of the cavity 5, and the limiting slide rod 13 is set through the connecting plate 6; by setting the limiting slide rod 13, the connecting plate 6 can be limited to ensure the stability of the connecting plate 6 when it moves.

[0019] Furthermore, the conical top block 4 is made of cemented carbide; by setting the conical top block 4 with cemented carbide material, the hardness of the conical top block 4 can be guaranteed, thereby ensuring the wear resistance of the conical top block 4.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
