Description

Technical Field

[0001] This utility model belongs to the field of automotive door panel mold technology, and relates to a large precision automotive door panel mold with a single mold and two cavities. Background Technology

[0002] Automotive door panels are an indispensable part of automobile manufacturing, providing safety for drivers and passengers. Under current technology, automotive door panels are mainly processed by injection molding. Traditional injection molds have a single-cavity structure, which means that only one door panel can be molded at a time, resulting in slow processing efficiency. Therefore, it is necessary to design a special double-cavity injection mold for automotive door panel processing. Summary of the Invention

[0003] The purpose of this invention is to provide a large-scale precision automotive door panel mold with a dual-cavity design to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solutions: A large precision automotive door panel mold with two cavities includes a base plate, a top plate, a lower mold base, and an upper mold base. The lower mold base is located at the top of the base plate. Inner forming mold 1 and inner forming mold 2 are respectively located on the top two sides of the lower mold base. Multiple push-out cavities are opened inside the inner forming mold 1 and inner forming mold 2, and inclined push-out blocks are arranged inside the push-out cavities. The upper mold base is located at the top of the lower mold base. Forming cavity 1 and forming cavity 2 are opened inside the upper mold base, and forming cavity 1 and forming cavity 2 cooperate with inner forming mold 1 and inner forming mold 2, respectively.

[0005] In the aforementioned large precision automotive door panel mold with two cavities, a support groove is provided on the side of the upper mold base, and a support column is provided on the side of the lower mold base, with the support column placed inside the support groove.

[0006] In the aforementioned large precision automotive door panel mold with two cavities, a stripper plate is provided between the base plate and the lower mold base, and a pusher base is provided at the top of the stripper plate. An inner slider is slidably provided inside the pusher base.

[0007] In the aforementioned large precision automotive door panel mold with a double cavity, the inner slider is movably connected to a movable block via a pin. A push rod is connected to the top of the movable block, and the top of the push rod is connected to the bottom of the inclined push block.

[0008] In the aforementioned large precision automotive door panel mold with two cavities, a feeding cylinder is installed on the side of the lower mold base. The output end of the feeding cylinder is connected to a cylinder push rod, and one end of the cylinder push rod is connected to the side of the stripper plate.

[0009] In the aforementioned large precision automotive door panel mold with a double cavity, multiple side support blocks are provided at the top edge of the upper mold base. The top of the upper mold base is supported by the multiple side support blocks, and a guide frame is provided between the multiple side support blocks. Multiple injection pump bodies are installed at the top of the guide frame.

[0010] Compared with existing technologies, the advantages of this utility model of a large precision automotive door panel mold with a single mold and two cavities are as follows: This application designs a specialized automotive door panel mold. Inside the lower mold are two parallel inner molding cavities, inner molding mold 1 and inner molding mold 2. Simultaneously, inside the upper mold are molding cavities 1 and 2. When the upper and lower mold bases are closed, inner molding mold 1 can enter molding cavity 1, and inner molding mold 2 can enter molding cavity 2, thus forming two independent injection mold cavities. Through injection from multiple injection pumps, the injection molten plastic can enter the two independent injection mold cavities. Therefore, during processing, two different automotive door panel structures can be processed in one operation. After cooling, the injection molded parts are ejected by multiple inclined ejector blocks. The entire processing is simple and efficient. Attached Figure Description

Forming cavity 1 12 and forming cavity 2 13 are opened inside the upper mold base 3, and forming cavity 1 12 and forming cavity 2 13 cooperate with inner forming mold 1 16 and inner forming mold 2 17, respectively.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model is a large precision automotive door panel mold with a single mold and two cavities. Specifically, a support groove 14 is provided on the side of the upper mold base 3, and a support column 15 is provided on the side of the lower mold base 2, with the support column 15 placed inside the support groove 14.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a large precision automotive door panel mold with a single mold and two cavities. Specifically, a stripper plate is provided between the base plate 20 and the lower mold base 2, and a pusher base 11 is provided at the top of the stripper plate. An inner slider is slidably provided inside the pusher base 11.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model is a large precision automotive door panel mold with a double cavity. Specifically, the inner slider is movably connected to a movable block 9 via a pin. The top of the movable block 9 is connected to a push rod 10, and the top of the push rod 10 is connected to the bottom of the inclined push block 19. The push rod 10 drives the inclined push block 19 to push out the injection molded part.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model relates to a large precision automotive door panel mold with a single mold and two cavities. Specifically, a material discharge cylinder 4 is installed on the side of the lower mold base 2. The output end of the material discharge cylinder 4 is connected to a cylinder push rod 5, and one end of the cylinder push rod 5 is connected to the side of the stripper plate. Multiple material discharge cylinders 4 are provided in this application, and they are mainly used for material discharge and demolding.

During processing, the molten plastic is fed through multiple nozzles and guided to the injection pump body 7 at different positions through the guide channel inside the guide frame 6. After the injection pump body 7 is opened, the molten plastic is injected into the two independent injection mold cavities. Thus, two different car door panel structures can be processed at one time. After cooling, when the internal injection molded parts need to be demolded, they can be directly ejected by multiple inclined ejector blocks 19. The entire processing process of this application is simple and efficient.
