Description

Technical Field

[0001] This application relates to the technical field related to the production of automotive parts, and specifically relates to an injection mold for split automotive plastic parts. Background Technique

[0002] Automotive parts are each unit that constitutes an entire vehicle and a product that serves the vehicle. With the development of the automotive industry, more and more molds are used in automobiles, and the shapes of products are becoming more and more complex. The requirements for the mold demoulding mechanism are also getting higher and higher. Due to the complex and variable parting surface and the relatively large shape of the mold, when designing the mold structure, it is necessary to consider as much as possible the convenience, speed of processing, ease of assembly, and feasibility of replacing parts in subsequent production. Traditional integral molds have the advantages of being structurally compact and having relatively high strength.

[0003] After retrieval, it is found that an injection mold for split automotive plastic parts is disclosed in the patent No. CN218838460U. In this injection mold, by using the compression rod and the spring in cooperation, when the upper mold and the lower mold are in cooperation, it can play a buffering effect to avoid excessive extrusion, and the threaded rod and the movable rod are in cooperation, so that when the threaded rod moves, it drives the movable rod to move, thereby driving the support plate to move, facilitating the removal of the lower mold.

[0004] However, in the actual injection process, the telescopic rod and the spring at the top of the upper mold can only play a buffering and extrusion effect, and the actual force-bearing effect of the mold is not significant, resulting in the inability to improve production efficiency. In view of this, we propose an injection mold for split automotive plastic parts. Summary of the Invention

Specific embodiments

[0034] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an injection mold for split automotive plastic parts provided by an embodiment of the present application includes a base 1 and a workbench 2. The workbench 2 is fixedly installed on the surface of the base 1. A lower mold 6 is arranged inside the workbench 2. An upper mold 5 is fixedly installed on the top of the workbench 2. A heating member 8 is fixedly installed at the bottom of the lower mold 6. The heating member 8 includes a heat conducting plate 82 for quickly heating the lower mold 6.

[0036] Refer to Figure 3 and Figure 4 , in one aspect of this embodiment, the heating member 8 further includes an electric heating box 80. A plurality of electric heating wires 81 are fixedly installed on the surface of the electric heating box 80. The heat conducting ends of the plurality of electric heating wires 81 are fixedly connected to the heat conducting plate 82.

[0037] Air boxes 9 are fixedly installed at both ends of the electric heating box 80. A plurality of exhaust fans 90 are rotatably installed inside the air boxes 9. The air direction of the air boxes 9 is inward air intake.

[0038] During the process of the upper mold 5 being fitted to the lower mold 6 for injection molding, the lower mold 6 will be fitted onto the heat conducting plate 82 under an extrusion state. At this time, the electric heating box 80 at the bottom operates to generate heat energy. This part of the heat energy will be delivered to the heat conducting plate 82 through multiple electric heating wires 81, so that the heat conducting plate 82 heats the lower mold 6, reducing the viscosity of the internal injection molding material to improve the injection molding efficiency. During the heating process, the air boxes 9 at both ends of the electric heating box 80 continuously blow air on the electric heating box 80 to ensure that the temperature of the heat conducting plate 82 is not affected. After production is completed, the drive motor 40 operates again, and the upper mold 5 is lifted from the lower mold 6 through the electric telescopic rod 41. At the same time, the height of the hydraulic rod 30 is adjusted so that the upper mold 5 disengages from above the lower mold 6. After the adjustment is completed, the telescopic support column 70 at the bottom can push the height of the lower mold 6 under the action of the high-strength spring 71, raising the position of the lower mold 6, thus facilitating the removal of the injection molding material inside the lower mold 6. After removal, subsequent production and processing can be carried out.

[0039] Referring to Figure 1 , Figure 2 and Figure 5 , in one aspect of this embodiment, the lifting member 3 includes a hydraulic rod 30. The top of the hydraulic rod 30 is fixedly installed with a lifting plate 31. The surface of the lifting plate 31 is fixedly installed with an adjusting member 4, and the upper mold 5 is fixedly connected to the adjusting member 4.

[0040] Slots 20 are opened at the four corners of the surface of the workbench 2. The size of the slots 20 is adapted to the size of the hydraulic rod 30.

[0041] The adjusting member 4 includes an electric telescopic rod 41. The electric telescopic rod 41 is fixedly installed on the surface of the lifting plate 31. One end of the electric telescopic rod 41 is fixedly connected to the upper mold 5, and the other end of the electric telescopic rod 41 passes through the lifting plate 31 and is electrically connected to the drive motor 40.

[0042] Support members 7 are fixedly installed at the four corners of the electric heating box 80. The support members 7 include telescopic support columns 70. The top ends of the telescopic support columns 70 are fixedly connected to the lower mold 6.

[0043] The support member 7 further includes a high-strength spring 71. The high-strength spring 71 is fixedly installed inside the telescopic support column 70.

[0044] When injection molding is required for plastic parts, the material is placed inside the lower mold 6, and the lifting member 3 is started synchronously, so that the hydraulic rod 30 can operate, driving the lifting plate 31 to move, so that the lifting plate 31 can be lowered to an appropriate height. After adjustment, the drive motor 40 operates, and the electric telescopic rod 41 is used to push the upper mold 5 to move until it fits onto the surface of the lower mold 6, squeezing and fixing the injection molding material. After the adjustment is completed, the hydraulic rod 30 and the electric telescopic rod 41 exert force, causing the upper mold 5 to squeeze the lower mold 6. During the squeezing process, the telescopic support column 70 at the bottom of the lower mold 6 supports and pads the lower mold 6. When the high-strength spring 71 inside the telescopic support column 70 is squeezed, the high-strength spring 71 exerts sufficient resilience on the telescopic support column 70, ensuring the stability of the lower mold 6 while also assisting the upper mold 5 in exerting force.

[0045] All electrical equipment in this solution is powered by an external power supply.

[0046] Working principle: When plastic parts need to be injection-molded, the material is placed inside the lower mold 6, and the lifting component 3 is started synchronously, so that the hydraulic rod 30 can operate, driving the lifting plate 31 to move, so that the lifting plate 31 can be lowered to an appropriate height. After adjustment, the drive motor 40 runs, and the electric telescopic rod 41 is used to push the upper mold 5 to move until it fits onto the surface of the lower mold 6, squeezing and fixing the injection-molded material. After the adjustment is completed, the hydraulic rod 30 and the electric telescopic rod 41 exert force, causing the upper mold 5 to squeeze the lower mold 6. During the squeezing process, the telescopic support column 70 at the bottom of the lower mold 6 supports and pads the lower mold 6. When the high-strength spring 71 inside the telescopic support column 70 is squeezed, the high-strength spring 71 exerts sufficient resilience on the telescopic support column 70, ensuring the stability of the lower mold 6 while also assisting the upper mold 5 in exerting force. During the injection-molding process when the upper mold 5 fits the lower mold 6, the lower mold 6 will fit onto the heat-conducting plate 82 under the squeezing state. At this time, the electric heating box 80 at the bottom operates to generate heat energy. This part of the heat energy is transmitted to the heat-conducting plate 82 through multiple electric heating wires 81, so that the heat-conducting plate 82 heats the lower mold 6, reducing the viscosity of the internal injection-molded material to improve the injection-molding efficiency. During the heating process, the air boxes 9 at both ends of the electric heating box 80 continuously blow air on the electric heating box 80 to ensure that the temperature of the heat-conducting plate 82 is not affected. After the production is completed, the drive motor 40 runs again, and the upper mold 5 is lifted from the lower mold 6 through the electric telescopic rod 41, and at the same time, the height of the hydraulic rod 30 is adjusted, so that the upper mold 5 is separated from above the lower mold 6. After the adjustment is completed, the telescopic support column 70 at the bottom can, under the action of the high-strength spring 71, push the height of the lower mold 6, so that the position of the lower mold 6 is lifted, facilitating the removal of the injection-molded material inside the lower mold 6. After removal, subsequent production and processing can be carried out.
