Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, specifically to the field of injection molding machine mold plates, and particularly to a mold plate fixing plate with an anti-deformation structure. Background Technology

[0002] The fixed mold plate is one of the components of an injection molding machine. Its rigidity and strength are major factors affecting the quality of the plastic products produced by injection molding. In actual operation, the moving and fixed mold plates of the injection molding machine's clamping mechanism are subjected to clamping force and expansion force. These two forces are characterized by their large size and concentration. Therefore, to reduce deformation, the moving and fixed mold plates are generally quite thick and heavy, increasing the overall weight of the injection molding machine, making handling and assembly difficult, and also increasing processing costs. Therefore, it is necessary to design the fixed mold plate to be lightweight, while ensuring that the deformation of the moving and fixed mold plates is within the allowable range and that they are subjected to good stress. For example, the website https: / / mp.weixin.qq.com / s / GDazONTRUv09E4oFdC78hg discloses the necessity of lightweight design for the fixed mold plate.

[0003] Based on the above viewpoints, a search revealed a Chinese utility model patent with authorization announcement number CN206663656U, which discloses a fixed template for an injection molding machine. It sets a connecting mechanism between the mold connecting plate and the tie rod connecting plate to achieve the effect of uniform force on the mold and make it less prone to deformation. However, it essentially increases the thickness of the fixed template, and the lightweight design has shortcomings and needs to be improved.

[0004] Based on this, the present invention proposes a fixed mold fixing plate with an anti-deformation structure. Utility Model Content

[0005] To address the problems mentioned in the background, this utility model provides a fixed mold fixing plate with an anti-deformation structure.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows.

[0007] A mold fixing plate with an anti-deformation structure includes a mold fixing plate body, and a set of deformation components are provided at each of the four corners of the mold fixing plate body. The deformation components are connected to the tie rod of the injection molding machine. The deformation components are used to transmit the pressure of the tie rod to the mold fixing plate body and can reduce the amount of deformation of the mold fixing plate body when the injection molding machine closes the mold.

[0008] As a further improvement and optimization of this utility model, the deformation component includes a notch provided at the corner of the fixed mold fixing plate body. The notch divides the corner of the fixed mold fixing plate body into two parts, namely a connecting section and a fixing section. The pull rod of the injection molding machine passes through the connecting section and is fixedly connected to the fixing section.

[0009] As a further improvement and optimization of this utility model, the sides of the fixed mold fixing plate body are provided with reinforcing ribs. Preferably, all four sides of the fixed mold fixing plate body are provided with reinforcing ribs.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] In this design, the corners of the fixed mold plate body are divided into a fixed section and a connecting section by a notch. In this way, when the mold is closed, the pressure of the injection molding machine tie rod is applied to the fixed mold plate body through the fixed section, rather than acting directly on the fixed mold plate body. Therefore, even if the pulling force of the injection molding machine is greater when the mold is closed, only the fixed section will deform, and the fixed mold plate body will not deform significantly. Of course, it should be noted that the fixed mold plate body will also undergo some deformation, but it is very small and does not affect the injection molding of the product after mold closing, so it can be ignored. In addition, the deformation at the fixed section is a plastic deformation and can recover.

[0012] In short, this solution enables a lightweight design for the fixed mold plate, making it less prone to deformation and resulting in negligible overall deformation. Therefore, when the injection molding machine closes the mold, the overall deformation of the fixed mold plate is small, thus reducing the clamping force and saving energy. With a smaller clamping force, the filling pressure is also reduced, thereby minimizing a series of problems caused by high pressure during product molding. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1-5 A mold fixing plate with an anti-deformation structure includes a mold fixing plate body 1. Each of the four corners of the mold fixing plate body 1 is provided with a set of deformation components. The deformation components are connected to the tie rod of the injection molding machine. The deformation components are used to transmit the pressure of the tie rod to the mold fixing plate body 1 and can reduce the amount of deformation of the mold fixing plate body 1 when the mold is closed.

[0022] Specifically, the deformation component includes a notch 2 located at the corner of the fixed mold plate body 1. The notch 2 divides the corner of the fixed mold plate body 1 into two parts, namely a connecting section 3 and a fixing section 4. The pull rod of the injection molding machine passes through the connecting section 3 and is fixedly connected to the fixing section 4.

[0023] Because of the notch 2, the corner of the fixed mold plate body 1 is divided into two parts. This means that during mold closing, the pressure from the injection molding machine's tie rod is applied to the fixed mold plate body 1 through the fixed section 4, rather than directly onto the fixed mold plate body 1. Therefore, even if the pulling force of the injection molding machine during mold closing is greater, it will only cause deformation at the fixed section 4, and will not cause significant deformation of the fixed mold plate body 1. Of course, it should be noted that the fixed mold plate body 1 will also undergo slight deformation, but this is very small and does not affect the injection molding of the product after mold closing; it can be ignored. In addition, the deformation at the fixed section 4 is a plastic deformation, which is recoverable and can be achieved by existing technology, so it will not be elaborated further. In short, this solution can make the fixed mold plate body 1 lightweight, so that it is not easy to deform and the overall deformation is small and negligible. Therefore, when the injection molding machine closes the mold, since the overall deformation of the fixed mold plate body 1 is small, the mold closing force can also be relatively smaller, which can save energy. With the mold closing force reduced, the filling pressure should also be smaller, and a series of problems caused by the high pressure during product molding will also be reduced.

[0024] In a preferred embodiment, the side of the fixed mold fixing plate body 1 is provided with reinforcing ribs 5. Furthermore, all four sides of the fixed mold fixing plate body 1 are provided with reinforcing ribs 5 to further improve the overall strength of the fixed mold fixing plate body 1.

[0025] In the attached diagram of this plan, Figures 2-5These are schematic diagrams of the fixed mold plate body 1 under different machine models. The shapes are different, but the principle is the same.

[0026] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
