Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, specifically a structure for positioning an injection molding machine and a mold. Background Technology

[0002] Existing injection molding machines and mold positioning, such as Figure 4 As shown, two positioning posts are fixed on the wall panel of the injection molding machine, and positioning grooves are opened on the mold. The positioning grooves and positioning posts are used to position the injection molding machine and the mold, making it convenient to install the mold on the injection molding machine. The center of the wall panel of the injection molding machine is provided with an installation hole, and a positioning ring is provided at the edge of the installation hole. The mold is provided with a positioning groove that mates with the positioning ring.

[0003] The advantages of the above scheme are: simple positioning structure and convenient mold hoisting and positioning.

[0004] The disadvantages of the above solution are: the mold is positioned by the positioning pin and the positioning ring is used as an auxiliary positioning. There is a risk of nozzle displacement and leakage. The positioning holes are machined in the existing injection molding machine wall plate and the positioning pin is embedded in the injection molding machine wall plate. The positioning holes in the injection molding machine wall plate are difficult to machine and the cost is relatively high. A large number of molds need to be modified, and the cost and cycle are long.

[0005] Therefore, it is necessary to provide a structure for positioning the injection molding machine and the mold to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a structure for positioning an injection molding machine and a mold.

[0007] This utility model provides a structure for positioning an injection molding machine and a mold, including an injection molding machine wall panel and a mold body. The injection molding machine wall panel has a mounting hole at its center, a flange is installed in the mounting hole, and a D-shaped connecting hole is provided on the inner side of the flange. The mold body has an integrally formed D-shaped protrusion that mates with the D-shaped connecting hole.

[0008] Preferably, the edge of the D-shaped protrusion is chamfered to facilitate the installation of the D-shaped protrusion into the D-shaped connecting hole.

[0009] Preferably, an insert that mates with the D-shaped protrusion is installed in the D-shaped connecting hole, and the insert can be replaced after it is worn.

[0010] Preferably, the end faces of the insert, flange, and injection molding machine wall panel are flush, resulting in a tighter connection between the injection molding machine and the mold.

[0011] Preferably, the flange is provided with stepped holes, and there are six stepped holes. The flange is fixedly connected to the injection molding machine wall panel by screws installed in the stepped holes, which facilitates installation, disassembly and replacement.

[0012] Preferably, both the injection molding machine wall panel and the mold body are provided with alignment lines, and the alignment lines are on the same straight line for auxiliary positioning and installation.

[0013] Usage process: Before hoisting the mold body, use the alignment lines for rough positioning, and then use the chamfered guide of the D-shaped protrusion for precise positioning.

[0014] Compared with related technologies, the present invention provides the following beneficial effects:

[0015] Before hoisting the mold body, rough positioning is performed using alignment lines, followed by precise positioning via the chamfered guide of the D-shaped protrusion. The positioning structure is simple, has low modification costs, and provides accurate positioning. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to 1- Figure 3 A structure for positioning an injection molding machine and a mold mainly includes an injection molding machine wall plate 1 and a mold body 2 (moving mold or fixed mold). A mounting hole 3 is provided at the center of the injection molding machine wall plate 1, and a flange 4 is installed in this mounting hole 3. Notably, a D-shaped connecting hole 5 is designed on the inner side of the flange 4, and the corresponding mold body 2 has an integrally formed D-shaped protrusion 6 that matches the D-shaped connecting hole 5. To facilitate the smooth installation of the D-shaped protrusion 6 into the D-shaped connecting hole 5, a chamfer 7 is provided at the edge of the D-shaped protrusion 6, which not only improves installation efficiency but also reduces wear between components.

[0023] Furthermore, considering the potential wear and tear from long-term use, a replaceable insert 9 is installed inside the D-shaped connection hole 5, which fits tightly with the D-shaped protrusion 6. Once the insert 9 wears down, the user can replace it individually without replacing the entire flange 4, thus reducing maintenance costs and extending the equipment's lifespan. In addition, the end faces of the insert 9, flange 4, and injection molding machine wall plate 1 are all flush, ensuring a tighter, gapless connection between the injection molding machine and the mold.

[0024] The flange 4 is provided with stepped holes 10, through which screws are used to securely fix the flange 4 to the injection molding machine wall plate 1. This design not only simplifies the installation process but also facilitates subsequent disassembly and replacement. In addition, both the injection molding machine wall plate 1 and the mold body 2 are provided with alignment lines 8. These two sets of alignment lines are located on the same straight line, providing auxiliary guidance for precise installation.

[0025] In actual operation, the alignment line 8 is first used for rough positioning, and then the chamfer 7 on the D-shaped protrusion 6 is used as a guide to accurately hoist the mold body 2 into place. This method not only improves the installation accuracy but also speeds up the assembly process, making the whole process smoother and more efficient.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
