Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring production, in particular to a sealing ring injection molding machine. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] When the existing injection molding machine produces sealing rings, it is not convenient to quickly interrupt the supply of raw materials after injection molding because the raw materials are relatively viscous, which causes the raw materials to easily overflow during injection molding, resulting in a waste of raw materials and further resulting in high production costs. Utility Model Content

[0004] The utility model provides a sealing ring injection molding machine, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A sealing ring injection molding machine comprises a buffer tank, a protective cover, an injection head and a mold, wherein a molding cavity is provided in the mold, a flow channel is provided inside the mold, a plug hole is provided on one side of the flow channel, and the plug hole and the molding cavity are connected through the flow channel, an injection head is plugged into the plug hole of the mold, a discharge port is provided through the injection head, and the position and size of the discharge port are adapted to the flow channel, a buffer tank is connected to the top of the injection head, a support plate is provided at the connection between the injection head and the buffer tank, and a protective cover is connected to the outside of the injection head through a spring.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the diameter of the plug hole is matched with the diameter of the injection head, and the diameter of the shield is larger than the diameters of the plug hole and the injection head.

[0009] The beneficial effects of adopting the above further scheme are:

[0010] The diameter of the plug hole matches the diameter of the injection head, ensuring a tight connection between the plug hole and the injection head. This tight connection can effectively prevent the leakage or loss of raw materials and maintain the stability and continuity of the injection molding process. The diameter of the shield is larger than the diameter of the plug hole and the injection molding head, so that the shield can completely cover the plug hole and the injection molding head. Through the effective closure of the shield, the raw materials can be prevented from being contaminated by the outside during the injection molding process, and the splashing or splashing of the raw materials can be prevented, thereby improving the safety of the working environment. Since the diameter of the shield is larger than the diameter of the plug hole and the injection molding head, it is difficult for impurities to enter the injection molding machine through the plug hole or the injection molding head. This can reduce the impact of impurities on the injection molding process and the quality of the finished product, and improve the consistency and reliability of the product.

[0011] Furthermore, the protective cover is supported by the elastic force of the spring and covers the discharge port of the injection molding head.

[0012] The beneficial effects of adopting the above further scheme are:

[0013] During the injection molding process, if the supply of raw materials exceeds the requirement, it may cause abnormal conditions in the injection molding machine or even safety accidents. By using shields and springs, the supply of raw materials can be effectively cut off, avoiding this situation and improving the safety and reliability of the injection molding machine. The supply of raw materials has a great influence on the stability of injection molding. If the supply of raw materials is unstable, it may cause inconsistencies in the size, weight and appearance of the product. By using shields and springs, the supply of raw materials can be ensured to be stable, improving the stability of injection molding and the consistency of products. The shield is supported by the elastic force of the spring and covers the discharge port of the injection head, which is convenient for cleaning, maintenance and replacement of the injection head. This design can reduce the work intensity of maintenance personnel and improve the maintenance efficiency of the injection molding machine. The use of shields and springs can directly cut off the supply of raw materials, avoiding the design and construction of complex mechanical structures and control systems, and reducing the manufacturing cost and maintenance cost of the injection molding machine.

[0014] Furthermore, the buffer tank is communicated with the interior of the injection head, and the raw material in the buffer tank is injected into the molding cavity of the mold through the discharge port of the injection head.

[0015] The beneficial effects of adopting the above further scheme are:

[0016] Through the design of the buffer tank, the continuous supply of raw materials can be achieved during the injection molding process, thereby improving the production efficiency of the injection molding machine. During the injection molding process, the buffer tank can store a large amount of raw materials to ensure the continuous operation of the injection molding machine, reduce downtime, and improve production efficiency. On traditional injection molding machines, there is often a large amount of waste of raw materials due to insufficient raw materials or downtime. The use of a buffer tank can avoid this situation, because the buffer tank can temporarily store raw materials when the injection molding machine is shut down, and replenish them when the injection molding machine resumes operation, thereby avoiding the waste of raw materials. During the injection molding process, the supply of raw materials has a great impact on the consistency of product size, weight and appearance. The use of a buffer tank can ensure a stable supply of raw materials, improve the stability of injection molding and the consistency of the product. The buffer tank is connected to the inside of the injection molding head, and the connection adopts an easy-to-disassemble structural design, which is convenient for cleaning, maintenance and replacement of the injection molding head. This design can reduce the workload of maintenance personnel and improve the maintenance efficiency of the injection molding machine.

[0017] The beneficial effects of the utility model are:

[0018] The sealing of this injection molding machine comes from multiple aspects of design. First, a molding cavity and a flow channel are opened inside the mold. The closed injection of raw materials is achieved through the connection between the plug hole and the flow channel. Secondly, a discharge port is opened throughout the injection head. The position and size are adapted to the flow channel, which can ensure that the raw materials can flow smoothly during the injection molding process and avoid leakage. Finally, the buffer tank is located at the top of the injection head and is connected to the inside of the injection head, which can ensure that the raw materials will not leak or be contaminated by the outside world when flowing from the buffer tank to the injection head.

[0019] The shield of the injection molding machine covers the outlet of the injection head through the elastic support of the spring, which can effectively cut off the supply of raw materials. This design helps to ensure the stability and safety of the injection molding process and avoid unnecessary waste, quality problems or safety accidents caused by excessive supply of raw materials.

[0020] The structure of the injection molding machine is relatively simple and compact. The plug hole is connected to the injection head, and the shield is supported by the elastic force of the spring to cover the discharge port of the injection head, thereby achieving the effect of cutting off the supply of raw materials. This structure can not only ensure the performance and safety of the injection molding machine, but also make the entire injection molding machine smaller and easier to operate and maintain.

[0021] In this injection molding machine, the diameter of the plug hole matches the diameter of the injection head, and the diameter of the shield is larger than the diameter of the plug hole and the injection head, which can ensure a tight connection and effective closure. This design helps to ensure the stability and quality of the raw materials during the injection molding process, and can adapt to raw materials of different models and specifications.

Through the design of the buffer tank 3, the continuous supply of raw materials can be realized during the injection molding process, thereby improving the production efficiency of the injection molding machine. During the injection molding process, the buffer tank 3 can store a large amount of raw materials to ensure the continuous operation of the injection molding machine, reduce downtime, and improve production efficiency. In traditional injection molding machines, there is often a large amount of waste of raw materials due to insufficient raw materials or downtime.

By using the shield 5 and the spring 2, the supply of raw materials can be effectively cut off, avoiding the occurrence of this situation and improving the safety and reliability of the injection molding machine. The supply amount of raw materials has a great influence on the stability of injection molding.

The shield 5 is supported by the elastic force of the spring 2 and covers the discharge port 10 of the injection head 7, which is convenient for cleaning, maintenance and replacement of the injection head 7. This design can reduce the workload of maintenance personnel and improve the maintenance efficiency of the injection molding machine.The use of the shield 5 and the spring 2 can directly cut off the supply of raw materials, avoid the design and construction of complex mechanical structures and control systems, and reduce the manufacturing cost and maintenance cost of the injection molding machine. The diameter of the plug hole 6 is compatible with the diameter of the injection head 7, and the diameter of the shield 5 is larger than the diameter of the plug hole 6 and the injection head 7. The diameter of the plug hole 6 is compatible with the diameter of the injection head 7, ensuring a tight connection between the plug hole and the injection head. This tight connection can effectively prevent the leakage or loss of raw materials and maintain the stability and continuity of the injection molding process. The diameter of the shield 5 is larger than the diameter of the plug hole 6 and the injection head 7, so that the shield 5 can completely cover the plug hole 6 and the injection head 7.

Secondly, a discharge port 10 is provided throughout the injection head 7, and its position and size are adapted to the flow channel 8, which can ensure that the raw material can flow smoothly during the injection molding process and avoid leakage. Finally, the buffer tank 3 is located at the top of the injection head 7 and is connected to the inside of the injection head 7, which can ensure that the raw material will not leak or be contaminated by the outside when flowing from the buffer tank 3 to the injection head 7.

[0037] The shield 5 of the injection molding machine is supported by the elastic force of the spring 2 and covers the discharge port 10 of the injection head 7, which can effectively cut off the supply of raw materials.
