Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection molding machine that is easy to maintain. Background Technology

[0002] In the field of injection molding machines, the injection head is a key component, and its installation method directly affects the maintenance efficiency and performance of the equipment.

[0003] Traditional injection molding machines commonly use threaded connections to secure the injection head. This structure has revealed significant drawbacks over long-term use. When disassembly and maintenance are required, the traditional threaded structure suffers from excessive engagement due to thermal stress, making disassembly extremely difficult. This often necessitates the use of specialized tools and significant external force, increasing maintenance time and labor intensity. Furthermore, forced disassembly can damage the threads or deform the equipment, affecting subsequent assembly accuracy and sealing performance. In addition, frequent and forceful disassembly shortens the lifespan of the injection head and connecting components, increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an injection molding machine that is easy to maintain. In actual use, this injection molding machine, compared to the traditional threaded installation method of the injection head, avoids the problem of tight connection at the thread due to heat conduction and difficulty in disassembly when blocked, thus facilitating the maintenance operation of the corresponding injection head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An injection molding machine that is easy to maintain includes an injection molding machine body, an injection molding seat installed on the left side of the injection molding machine body, an injection molding head inserted into the injection molding seat, and a limiting mechanism. The limiting mechanism includes a limiting cylinder fixedly connected to the lower side of the injection molding head. A connecting plate is fixedly connected to the left side of the injection molding machine body, and a sliding cylinder is fixedly connected to the upper end of the connecting plate. A sliding plate that can slide up and down is provided inside the sliding cylinder. A limiting rod is fixedly connected to the upper end of the sliding plate, and the upper end of the limiting rod extends into the limiting cylinder. A spring is provided inside the sliding cylinder, and the upper and lower ends of the spring contact the sliding plate and the bottom of the sliding cylinder, respectively.

[0007] Preferably, the outer side of the spring contacts the inner wall of the sliding cylinder and is slidably connected.

[0008] Preferably, both the upper and lower end faces of the spring are horizontal.

[0009] Preferably, the inner bottom of the sliding cylinder and the connecting plate are both provided with a circular opening, and a pulling rod is fixedly connected to the lower end of the sliding plate. The lower end of the pulling rod passes through the circular opening and extends to the outside.

[0010] Preferably, a heat insulation pad is provided on the outer side of the injection head.

[0011] Preferably, a guide groove is provided on the inner side wall of the injection molding base, and a guide strip is fixedly connected to the outer side of the injection head. The guide strip contacts the inner wall of the guide groove and is slidably connected.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. When inspecting the injection head, simply pull down the pull rod to move the limit rod out of the limit cylinder, release the limit, and quickly pull out the injection head for inspection. The operation is simple, greatly shortens the inspection time, reduces the difficulty of inspection, and improves the efficiency of equipment maintenance.

[0014] 2. When the spring needs to be replaced after long-term use, without the injection head, pull the pull rod upward to remove the whole part, take out the old spring and replace it with a new spring, and then reassemble the whole. The operation is simple and facilitates the long-term stable operation of the equipment. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 An injection molding machine that is easy to maintain includes an injection molding machine body 1. An injection molding seat 2 is installed on the left side of the injection molding machine body 1. An injection molding head 3 is inserted into the injection molding seat 2. A heat insulation pad 4 is provided on the outside of the injection molding head 3. The heat insulation pad 4 facilitates the handling of the injection molding head 3 and avoids the situation where the internal high temperature is transmitted and burns the operator when it is blocked. In addition, an annular sealing gasket is installed at the contact point between the injection molding head 3 and the injection molding seat 2 to ensure the connection is sealed.

[0021] The system also includes a limiting mechanism, which includes a limiting cylinder 8 fixedly connected to the lower side of the injection head 3. A connecting plate 5 is fixedly connected to the left side of the injection molding machine body 1. A sliding cylinder 9 is fixedly connected to the upper end of the connecting plate 5. A sliding plate 10 that can slide up and down is provided inside the sliding cylinder 9. A limiting rod 11 is fixedly connected to the upper end of the sliding plate 10. The upper end of the limiting rod 11 extends into the limiting cylinder 8. A spring 12 is provided inside the sliding cylinder 9. The upper and lower ends of the spring 12 contact the sliding plate 10 and the bottom of the sliding cylinder 9, respectively. The outer side of the spring 12 contacts the inner wall of the sliding cylinder 9 and is slidably connected. The upper and lower end faces of the spring 12 are both horizontal. After long-term use, the spring 12 can be replaced. Specifically, when the injection head 3 is not in use, the entire assembly formed by the limiting rod 11, the sliding plate 10, and the pull rod 14 can be pulled out, and then the spring 12 can be removed and replaced with a new spring.

[0022] Among them, a guide groove 7 is provided on the inner side wall of the injection molding base 2, and a guide strip 6 is fixedly connected to the outer side of the injection molding head 3. The guide strip 6 contacts the inner wall of the guide groove 7 and is slidably connected. The guide groove 7 and the guide strip 6 facilitate the positioning operation.

[0023] The inner bottom of the sliding cylinder 9 and the connecting plate 5 are connected by a circular opening 13. The lower end of the sliding plate 10 is fixedly connected to a pull rod 14, the lower end of which passes through the circular opening 13 and extends to the outside.

[0024] In this invention, when the injection head 3 needs to be inspected, the pull rod 14 is pulled down. The pull rod 14 causes the sliding plate 10 to slide downwards within the sliding cylinder 9. The sliding plate 10 compresses the spring 12, simultaneously causing the limiting rod 11 to move downwards, so that the upper end of the limiting rod 11 moves out of the limiting cylinder 8, releasing the limitation on the injection head 3. At this time, the injection head 3 can be pulled out of the injection base 2 for inspection.

[0025] When the maintenance is completed and installation is carried out, with the pull rod 14 pulled down, the guide strip 6 on the outside of the injection head 3 is aligned with the guide groove 7 on the inner side wall of the injection seat 2, so that the guide strip 6 slides along the guide groove 7 to achieve the initial positioning of the injection head 3. After the injection head 3 is installed in place, the pull rod 14 is released. Under the elastic force of the spring 12, the sliding plate 10 slides upward, driving the limit rod 11 to move upward, so that the upper end of the limit rod 11 extends into the limit cylinder 8, thereby achieving the limit locking of the injection head 3 and ensuring the stability of the injection head 3 during use.

[0026] If spring 12 needs to be replaced after prolonged use, without the injection head 3, pull the pull rod 14 upwards to move the entire assembly formed by the limiting rod 11, sliding plate 10, and pull rod 14 upwards until it can be pulled out of the sliding cylinder 9. Then remove the old spring 12, replace it with a new spring 12, and then reassemble the entire assembly formed by the limiting rod 11, sliding plate 10, and pull rod 14 back into the sliding cylinder 9 to complete the replacement of spring 12.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
