Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an anti-deviation injection mold. Background Technology

[0002] Injection molds are precision tools used for molding plastic products. They are formed by injecting molten plastic at high temperatures into a mold cavity, which then cools and solidifies to create a product of a specific shape.

[0003] However, in the existing technology, the upper mold of the existing injection mold is generally fixedly installed on the moving platen of the injection machine, and the lower mold is generally installed on the fixed platen of the injection machine. Due to the lack of a mechanism to prevent the upper and lower molds from shifting, the upper and lower molds may not be on the same axis after they are installed on the injection machine. This may cause deviations when the two are connected, resulting in poor connection and affecting the injection quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: due to the general lack of a mechanism to prevent the upper and lower molds from shifting, the upper and lower molds may not be on the same axis after being installed on the injection molding machine. This can lead to deviations when the two are joined together, resulting in poor jointing and affecting the injection molding quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-deviation injection mold, comprising an upper mold and a lower mold, wherein a top plate and a bottom plate are fixedly connected to one side surface of the upper mold and the lower mold respectively, and a short column and a long column are fixedly connected to the two side edges of the top plate and the bottom plate respectively, wherein a bracket is fixedly connected to the top of the long column and the bracket is fixedly connected to the bottom plate, wherein a threaded column is threaded to one end of the short column and a torsion plate is fixed to one end of the threaded column, wherein a connecting plate is slidably inserted through the outer surface of the short column, and a movable column is fixed to the lower end of the connecting plate, wherein the movable column is connected through the bracket, and a limit plate is fixed to the bottom end of the movable column.

[0006] In a preferred embodiment, the surfaces of the top plate and the bottom plate are fixedly connected with reinforcing collars at the installation positions of the short column and the long column.

[0007] In a preferred embodiment, the outer edge of the torsion disc is fixedly connected with anti-slip protrusions.

[0008] In a preferred embodiment, a positioning block is fixedly connected to the end of the torsion disc away from the threaded column, and the positioning block is interlocked with the long column.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] In this invention, when the upper and lower molds are installed on the moving and fixed templates of the injection molding machine, the movable column in the connecting plate, which is restricted on the short column, moves linearly on the support with the help of the torsion disc and the threaded column. With the cooperation of the movable column and the support, the upper and lower molds can be kept on the same axis when they are separated and moved, which ensures that they are installed on the injection molding machine and reduces the occurrence of docking deviations in subsequent use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1-4As shown, this utility model provides a technical solution: an anti-deviation injection mold, including an upper mold 1 and a lower mold 2. A top plate 3 and a bottom plate 4 are fixedly connected to one side surface of the upper mold 1 and the lower mold 2, respectively. Short columns 6 and long columns 7 are fixedly connected to the two side edges of the top plate 3 and the bottom plate 4, respectively. A bracket 8 is fixedly connected to the top of the long column 7, and the bracket 8 is fixedly connected to the bottom plate 4. When the upper mold 1 and the lower mold 2 are separated and installed on the moving template and the fixed template on the injection molding machine, with the help of the torsion disc 9 and the threaded column 11, the movable column 14 in the connecting plate 13, which is restricted on the short column 6, moves linearly on the bracket 8. With the cooperation of the movable column 14 and the bracket 8, the upper mold 1 and the lower mold 2 can be kept on the same axis when they are separated and moved, reducing the possibility of deviation. One end of the short column 6 is threadedly connected to the threaded column 11, and one end of the threaded column 11... A torsion disc 9 is fixed, and a connecting plate 13 slides through the outer surface of the short column 6. A movable column 14 is fixed at the lower end of the connecting plate 13. The movable column 14 is connected to the bracket 8, and a limit plate 15 is fixed at the bottom end of the movable column 14. With the help of the limit plate 15, the movement of the movable column 14 on the bracket 8 is limited, reducing the possibility of it disengaging from the bracket 8. When the upper mold 1 and the lower mold 2 need to be repaired after long-term use, the threaded column 11 is rotated by twisting the torsion disc 9, and the threaded column 11 is removed from the short column 6. This releases the torsion disc 9 from the movement of the connecting plate 13 on the short column 6, allowing the connecting plate 13 to detach from the short column 6. This allows the upper mold 1 and the lower mold 2 to move linearly without coaxiality, completing the disassembly of the upper mold 1 and the lower mold 2, and facilitating separate repair of the upper mold 1 and the lower mold 2.

[0020] Example 2

[0021] like Figure 1-4 As shown, reinforcing collars 5 are fixedly connected to the surfaces of the top plate 3 and the bottom plate 4 at the installation positions of the short column 6 and the long column 7. The reinforcing collars 5 strengthen the connection between the short column 6 and the long column 7 on the top plate 3 and the bottom plate 4, improving the stability of their vertical installation and reducing the impact of tilting of the short column 6 and the long column 7 on the normal connection between the positioning block 12 and the long column 7. Anti-slip protrusions 10 are fixedly connected to the outer edge of the torsion disk 9. With the help of the anti-slip protrusions 10, the friction of the outer surface of the torsion disk 9 is increased, thereby effectively preventing slippage when the torsion disk 9 is manually twisted. A positioning block 12 is fixedly connected to the end of the torsion disk 9 away from the threaded column 11, and the positioning block 12 is interlocked with the long column 7. When the upper mold 1 and the lower mold 2 are well aligned, the positioning block 12 will be interlocked with the long column 7, which further improves the stability when the upper mold 1 and the lower mold 2 are well aligned.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
