Description

Technical Field

[0001] The invention relates to the technical field of a mold clamping valve plate of an injection molding machine, in particular to a side hanging structure of a mold clamping valve plate of an injection molding machine. Background Art

[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 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 small space makes installation and disassembly more difficult, and some locations of the mold clamping valve plate may be difficult to access. Especially in large or multi-functional injection molding machines, the mold clamping valve plate usually needs to be connected to multiple hydraulic pipelines, and the existing pipeline installation method usually requires manual assistance to fix the pipeline during installation so that the bolt holes can be aligned, which greatly affects the installation efficiency. In view of this, a side-hanging structure of the mold clamping valve plate of an injection molding machine is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a side hanging structure of a mold clamping valve plate of an injection molding machine, which solves the problem of inconvenient installation of the mold clamping valve plate.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a side hanging structure of a mold clamping valve plate of an injection molding machine, comprising an injection molding machine, wherein the injection molding machine comprises a mold clamping valve plate installed on the side wall of the injection molding machine through an installation mechanism and an installation plate, and a steel pipe is detachably installed on the top of the mold clamping valve plate through a limiting mechanism, and the steel pipe is used to improve durability and service life;

[0007] The mounting mechanism includes an electromagnet, which is fixedly connected to the outer wall of a mounting plate, and the mounting plate is fixedly connected to the outer wall of an injection molding machine by bolts. An iron magnet is fixedly connected to the back side wall of the mold clamping valve plate, and the iron magnet is used to cooperate with the electromagnet to generate an adsorption force to adsorb and fix the mold clamping valve plate.

[0008] Preferably, a guide rail is fixedly connected to the outer side wall of the mounting plate, an opening is provided at the outer end of the guide rail, the inner track gradually tilts downward from the horizontal to form a bend, and then tilts upward at an angle to form a low point with a certain curvature at the opening, a connecting block is fixedly connected to the back side wall of the clamping valve plate, a slider is fixedly connected to the outer side wall of the connecting block, both ends of the slider are convex, the distance between them is consistent with the width of the guide rail, and can be just stuck in the guide rail without causing left and right lateral movement.

[0009] Preferably, a shock absorbing damper is fixedly connected to the back side wall of the mold clamping valve plate to mitigate the vibration generated during the operation of the mold clamping valve plate.

[0010] Preferably, the outer wall of the sliding block is slidably connected to the inner wall of the guide rail, and a cooling mechanism is provided on the outer side wall of the mounting plate.

[0011] Preferably, the cooling mechanism includes two groups of support frames, the side walls of the two groups of support frames are fixedly connected to the outer wall of the mounting plate, the two groups of support frames are arranged opposite to each other, and a cooling fan is arranged on the inner wall of the support frame. After the mold valve plate is installed, there is still a certain gap between it and the mounting plate, so that the heat generated inside can be blown out through the gap to avoid excessive temperature of the electromagnet.

[0012] Preferably, the limiting mechanism includes a limiting block, and the limiting blocks are provided in several groups and are 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 as the center. A sealing gasket is provided at the end of the steel pipe, and a sealing sleeve is sleeved on the outer wall of the steel pipe. The bottom end of the limiting block passes through and is slidably connected to a moving block, and the top of the moving block is elastically connected to the inner wall of the limiting block through a reset spring.

[0013] Preferably, a pressing groove, an annular groove and a guide groove are provided at the top of the mold clamping valve plate near the pipeline connection, and the pressing groove is snap-fitted with the sealing sleeve, and the sealing effect can be improved through the snap-fitting therebetween.

[0014] Preferably, a through opening is provided at the top of the limit block, and the limit block is fixed by passing a self-locking bolt through the through opening and the bolt hole.

[0015] Preferably, a plurality of groups of bolt holes are provided at the top of the mold clamping valve plate between the annular groove and the pressing groove.

[0016] Preferably, the outer wall of the moving block is slidably connected to the inner wall of the annular groove, and the bottom end of the moving block is clamped on the inner wall of the guide groove, which can prevent the moving block from falling off.

[0017] Working principle: When the injection molding machine is processing, the electromagnet is energized to generate electromagnetic force, thereby adsorbing the iron plate to fix the mold valve plate. When the injection molding machine stops working, the electromagnet is powered off, and the adsorption force on the iron plate is lost. When the mold valve plate needs to be repaired, the self-locking bolts on the limit blocks are removed, and several groups of limit blocks are rotated to one side. At this time, the steel pipe can be lifted up and moved out horizontally, and then the associated pipelines at the bottom are removed, and the mold valve plate is moved outward along the guide rail. When it moves to the low point of the guide rail opening, it will slide to the low point. At this time, the mold valve plate can be repaired. When it needs to be disassembled, lift it up with force to take out the mold valve plate. The disassembly process is simple and convenient, which greatly reduces the installation and disassembly time.

[0018] The present invention provides a side hanging structure of a mold clamping valve plate of an injection molding machine. It has the following beneficial effects:

[0019] 1. The present invention improves the installation and disassembly efficiency of the mold clamping valve plate by hanging the mold clamping valve plate on the side and by adsorption between the electromagnet and the magnetic plate. Due to the design of the side hanging structure, the mold clamping valve plate can be easily installed and disassembled from the side of the injection molding machine, avoiding the difficulty of operating in a narrow space in the traditional installation method. At the same time, the mold clamping valve plate can be easily disassembled from the injection molding machine, which is convenient for daily maintenance and servicing, and improves the operating efficiency and stability of the injection molding machine.

[0020] 2. The present invention provides a cooling mechanism on the outer side wall of the mounting plate so that the heat generated by the clamping valve plate during operation can be effectively dissipated, thereby preventing the electromagnet from being affected in performance due to excessive temperature.

[0021] 3. The present invention uses steel pipes instead of rubber pipes, which can significantly improve the durability and service life of the system because steel pipes can withstand mechanical shock and pressure better than rubber pipes. Traditional rubber pipes may generate greater tension when pressure is applied, which may cause damage to the hoses. Using steel pipes for fixing can effectively reduce the impact of tension on the connectors, thereby improving the stability of the system.

[0022] 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 initially positioned during installation without manual assistance for stabilization, which makes pipeline installation simpler and more convenient, greatly improving the installation efficiency.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] Please refer to the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a side hanging structure of a mold clamping valve plate of an injection molding machine, including an injection molding machine 1, wherein the injection molding machine 1 includes a mold clamping valve plate 2 installed 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 clamping valve plate 2 receives high-pressure hydraulic oil from an oil pump, and through its control, pushes the piston of the mold clamping 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 installed on the top of the mold clamping 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 the steel pipe 3 can effectively reduce the influence of tension on the connector, thereby improving the stability of the system.

[0036] Please refer to the attached Figure 4 -Attached Figure 5 The mounting mechanism 5 includes an electromagnet 51, which is fixedly connected to the outer side wall of the mounting plate 4. The mounting plate 4 is fixedly connected to the outer side wall of the injection molding machine 1 by bolts. The electromagnet 51 is a device that generates electromagnetic 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, a strong magnetic force can be generated, 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 in operation.

[0037] Please refer to the attached Figure 4 -Attached Figure 5A guide rail 52 is fixedly connected to the outer wall of the mounting plate 4. An opening is arranged at the outer end of the guide rail 52. The inner track gradually tilts downward from the horizontal to form a bend, 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 back side wall of the 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, so that 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 arranged 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 arranged on the inner wall of the support frame 61. After the mold clamping valve plate 2 is installed, it still has a certain gap from the mounting plate 4, so that the heat generated inside can be blown out through the gap to avoid the electromagnet 51 from being overheated.

[0038] Please refer to the attached Figure 6 -Attached Fig. 9 The limiting mechanism 9 includes a limiting block 91, and the limiting block 91 is provided with several groups, which are arranged in a circular array with the center of the circle at the pipeline installation port at the top of the mold clamping valve plate 2 as the center. A sealing gasket 8 is provided at the end of the steel pipe 3, and a sealing sleeve 7 is sleeved 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 clamping 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, which can prevent the moving block 93 from falling off. The top of the moving block 93 is connected to the reset spring 97 One end of the limit block 91 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. A plurality of 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 passing the through opening 92 and the bolt hole with a self-locking bolt. When installing the pipeline, a plurality of 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.

[0039] In summary, the side hanging structure of the mold clamping valve plate of the injection molding machine of the present invention not only improves the installation and disassembly efficiency of the mold clamping valve plate, but also enhances its durability and service life, while providing a good cooling effect and facilitating repair and maintenance, and has significant technical advantages and application value.
