[0002] Injection molding machine is a kind of equipment widely used in manufacturing plastic parts. Its basic principle is to heat and melt the plastic raw materials and inject them into the mold, and then cool and solidify to obtain the molded product.

[0003] The clamping valve plate (also called the clamping valve plate or mold clamping valve plate) is one of the key components in the injection molding machine. It is used to control the opening and closing of the mold. It plays a vital role in the clamping unit of the injection molding machine, ensuring that the mold can be tightly closed during the injection molding process and can be opened and closed when necessary.

[0004] However, in the prior art, the traditional mold clamping valve plate is partially located inside the equipment or in a complex structure. The narrow space makes installation and disassembly more difficult, and some positions of the mold clamping valve plate may be difficult to access.

[0028] 1. The present invention improves the installation and disassembly efficiency of the mold closing valve plate by hanging the mold closing valve plate on the side and through the adsorption between the electromagnet and the iron absorption plate. Due to the design of the side hanging structure, the mold closing valve plate can be easily installed and disassembled from the side of the injection molding machine, avoiding the difficulty of operating in a small space in the traditional installation method.

Using steel pipes for fixing can effectively reduce the impact of tension on the connectors, thereby improving the stability of the system.

[0031] 4. The present invention uses a limiting mechanism to enable the device to quickly install the steel pipe through the limiting mechanism, and the steel pipe can be preliminarily positioned during installation without the need for manual assistance for stabilization.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Please see the attached Figure 1 -Attached Figure 3 , an embodiment of the present invention provides a side-hanging structure of a mold closing valve plate of an injection molding machine, comprising an injection molding machine 1, wherein the injection molding machine 1 comprises a mold closing valve plate 2 mounted on the side wall of the injection molding machine 1 through a mounting mechanism 5 and a mounting plate 4. During the injection molding process, the mold closing valve plate 2 serves to receive high-pressure hydraulic oil from an oil pump, and through its control, pushes the piston of the mold closing cylinder forward to close the mold. This is an existing injection molding process well known to those skilled in the art, and its principle will not be described in detail here. A steel pipe 3 is detachably mounted on the top of the mold closing valve plate 2 through a limiting mechanism 9. The steel pipe 3 can significantly improve the durability and service life of the system because the steel pipe 3 can withstand mechanical shock and pressure better than a rubber hose. A traditional rubber hose may generate greater tension when pressure is applied, which may cause damage to the rubber hose. Fixing with a steel pipe 3 can effectively reduce the influence of tension on the connector, thereby improving the stability of the system.

[0044] Please see the attached Figure 4 -Attached Figure 5 The mounting mechanism 5 includes an electromagnet 51, which is fixedly connected to the outer wall of the mounting plate 4. The mounting plate 4 is fixedly connected to the outer wall of the injection molding machine 1 by bolts. The electromagnet 51 is a device that generates electromagnetics when energized. An iron-absorbing plate 55 is fixedly connected to the back side wall of the mold clamping valve plate 2. When the electromagnet 51 is energized, it can generate a strong magnetic force, which can be determined by the actual power. At this time, the iron-absorbing plate 55 behind the mold clamping valve plate 2 can be adsorbed, thereby fixing the mold clamping valve plate 2 to prevent it from moving. A shock-absorbing damper 56 is fixedly connected to the back side wall of the mold clamping valve plate 2. When the electromagnet 51 generates a strong magnetic force to adsorb the iron-absorbing plate 55, the shock-absorbing damper 56 will contact the mounting plate 4 and generate compression, which can play a partial shock-absorbing role when the mold clamping valve plate 2 is running.

[0045] Please see the attached Figure 4 -Attached Figure 5 A guide rail 52 is fixedly connected to the outer wall of the mounting plate 4. An opening is provided at the outer end of the guide rail 52. The inner track gradually tilts downward from the horizontal to form a curve, and then tilts upward at an angle to form a low point with a certain arc at the opening. A connecting block 53 is fixedly connected to the side wall of the back of the mold clamping valve plate 2. A slider 54 is fixedly connected to the outer wall of the connecting block 53. Both ends of the slider 54 are convex. The distance between them is consistent with the width of the guide rail 52, and it can be just stuck in the guide rail 52 without causing left and right movement. The outer wall of the slider 54 is slidably connected to the inner wall of the guide rail 52, and a cooling mechanism 6 is provided on the outer wall of the mounting plate 4. The cooling mechanism 6 includes two groups of support frames 61. The side walls of the two groups of support frames 61 are fixedly connected to the outer wall of the mounting plate 4. The two groups of support frames 61 are arranged opposite to each other. A cooling fan 62 is provided on the inner wall of the support frame 61. After the mold closing valve plate 2 is installed, there is still a certain gap between it and the mounting plate 4, which can make the heat generated inside be blown out through the gap to avoid the electromagnet 51 from being too hot.

[0046] Please see the attached Figure 6 -Attached Figure 9The limiting mechanism 9 includes a limiting block 91. The limiting block 91 is provided with several groups and is arranged in a circular array with the center of the circle at the pipeline installation port at the top of the mold closing valve plate 2 as the center. A sealing gasket 8 is provided at the end of the steel pipe 3. A sealing sleeve 7 is provided on the outer wall of the steel pipe 3. The bottom of the sealing sleeve 7 has an opening. The bottom end of the limiting block 91 passes through and is slidably connected with a moving block 93. A pressing groove 94, an annular groove 95 and a guide groove 96 are provided at the top of the mold closing valve plate 2 near the pipeline connection. The pressing groove 94 is clamped with the sealing sleeve 7. The clamping therebetween can improve the sealing effect. The outer wall of the moving block 93 is slidably connected to the inner wall of the annular groove 95, and the bottom end of the moving block 93 is clamped on the inner wall of the guide groove 96 to prevent the moving block 93 from falling off. The top of the moving block 93 is connected to the reset spring 97 One end is fixedly connected, and the other end of the return spring 97 is fixedly connected to the inner wall of the limit block 91. The elasticity of the return spring 97 can make the limit block 91 have a certain space to move downward and provide a reset function. Several groups of bolt holes are provided at the top of the mold closing valve plate 2 between the annular groove 95 and the pressing groove 94. A through opening 92 is provided at the top of the limit block 91, and the limit block 91 is fixed to the limit block 91 by self-locking bolts passing through the through opening 92 and the bolt hole. When installing the pipeline, several groups of limit blocks 91 can be moved to one side, and then the steel pipe 3 can be moved horizontally to make the sealing sleeve 7 engage with the notch on the inner side of the limit block 91, and then the limit block 91 is moved along the annular groove 95 until the sealing sleeve 7 is initially stuck, and then the self-locking bolt can be used to tighten it.

[0047] Working principle: When the injection molding machine 1 is processing, the electromagnet 51 is energized, so that the electromagnet 51 generates electromagnetic force, thereby adsorbing the iron plate 55 to fix the mold valve plate 2. When the injection molding machine 1 stops working, the electromagnet 51 is powered off, and the adsorption force on the iron plate 55 is lost. When the mold valve plate 2 needs to be repaired, the self-locking bolts on the limit blocks 91 are removed, and several groups of limit blocks 91 are rotated to one side. At this time, the steel pipe 3 can be lifted upward and moved horizontally out, and then the associated pipeline at the bottom is removed, and the mold valve plate 2 is moved outward along the guide rail 52. When it moves to the low point at the opening of the guide rail 52, it will slide to the low point. At this time, the mold valve plate 2 can be repaired. When it needs to be disassembled, it can be lifted up with force to take out the mold valve plate 2. The disassembly process is simple and convenient, which greatly reduces the installation and disassembly time.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
