It is usually made of a mixture or composite material of rubber and plastic to obtain properties that combine the advantages of rubber and plastic. It is mainly used for thermal insulation, heat insulation, sealing and shock absorption. When producing and processing rubber-plastic pipe, a rubber-plastic pipe extrusion die is generally used to extrude the material.

[0003] Existing technologies such as the patent publication number CN210061938U disclose a rubber and plastic pipe extrusion die. The patent adopts a mouth die and a core die, and the discharge end of the mouth die is provided with a first light-enhancing ring. The discharge end of the core die is provided with a second light-enhancing ring, and the first and second light-enhancing rings are both made of polytetrafluoroethylene. The discharge end of the mouth die is also provided with a pressure ring, and the middle part of the pressure ring is provided with a stepped hole that is smaller at the top and larger at the bottom, and the aperture of the large hole of the stepped hole is adapted to the outer diameter of the first light-enhancing ring. The first light-enhancing ring is inserted into the stepped hole, and the pressure ring is detachably connected to the mouth die, and the pressure ring is used to tighten the first light-enhancing ring. The discharge end of the core die is also provided with a circular pressure block, and the pressure block is a stepped shaft that is larger at the top and smaller at the bottom, and the outer diameter of the small diameter section of the pressure block is adapted to the inner diameter of the second light-enhancing ring. The second light-enhancing ring is sleeved on the small-diameter section of the pressing block, and the pressing block is detachably connected to the core mold. The pressing block is used to fasten the second light-enhancing ring. The equipment of the utility model solves the technical problem that the light-enhancing block at the extrusion end of the existing extruder is easily deformed, resulting in poor quality of the finished pipe product.

[0004] In daily work, when the equipment is producing and processing materials, there is a problem that when the equipment extrudes the materials to form pipes, the newly extruded pipes are easily affected by their own gravity and fall, causing the pipes to shrink inward, affecting the finished products of the pipes and causing the pipes to have different shapes. Utility Model Content

[0007] Furthermore, a partition block is fixedly connected to the middle end of the forward and reverse threaded rod, and the forward and reverse threaded rod is connected to the internal rotation of the two support frames. By setting the forward and reverse threaded rod, the two connecting plates can be moved in opposite directions, which reduces the difficulty of the two connecting plates moving in opposite directions at the same speed when the equipment is in use, resulting in unequal spacing between the connecting plates.

[0008] Furthermore, both ends of the forward and reverse threaded rod are fixedly connected with positioning blocks, and one end of the forward and reverse threaded rod is fixedly connected with a motor. By providing the positioning blocks, the forward and reverse threaded rod can be easily limited in rotation.

[0009] Furthermore, a connecting seat is fixedly connected to the surface of the motor, and the connecting seat is fixedly connected to the side surface of the connecting frame.

[0010] Furthermore, a connecting device is provided at the lower end of the extrusion head, and the connecting device includes a fixed block and a connecting groove. The fixed block is fixedly connected to the lower end of the extrusion head, and the connecting groove is opened on the side of the fixed block. The connecting frame is clamped with the inside of the connecting groove. A pressure hole is opened inside the end of the connecting frame close to the fixed block, and a clamping groove is opened inside the connecting groove. The inner wall of the pressure hole is slidably connected to a pressure rod.

[0011] Furthermore, one end of the pressure rod is fixedly connected to a clamping plate, one end of the clamping plate is clamped with the inside of the clamping slot, and the clamping plate is used to limit the connecting frame.

[0012] Furthermore, one end of the card plate away from the card slot is fixedly connected to a spring, and one end of the spring away from the card plate is fixedly connected to the inside of the pressure hole, and the spring is used to apply a reset elastic force to the card plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up a supporting device, the material extruded from the inside of the extruder head is effectively supported, which plays a role in supporting the material. When the equipment extrudes the material to form a pipe discharge, the newly extruded pipe is easily affected by its own gravity and falls, causing the pipe to shrink inward, affecting the finished product of the pipe and causing the pipe to appear in different shapes.

[0015] 2. By setting up a connecting device, the connecting frame and the extrusion head are effectively connected, which plays a role in quickly installing and connecting the connecting frame. When the equipment is installing the connecting frame, bolts are generally used for installation and fixing. The installation and removal of the bolts require the use of tools.

The connecting frame 51 is provided at the end of the extrusion head 2 away from the mounting disc 1, and the two supporting frames 52 are located on both sides of the connecting frame 51 and fixedly connected. Two connecting plates 53 are provided at the middle ends of the two supporting frames 52, and the upper ends of the two connecting plates 53 are fixedly connected to support plates 54. The ends of the two connecting plates 53 close to the support frames 52 are fixedly connected to limit rods 55, and the limit rods 55 are slidably connected to the inside of the support frames 52. The ends of the limit rods 55 away from the connecting plates 53 are fixedly connected to limit blocks 56, and the internal threads of the two connecting plates 53 are connected with positive and negative threaded rods 58. The middle end of the forward and reverse threaded rod 58 is fixedly connected to the partition block 57, and the forward and reverse threaded rod 58 is rotatably connected to the inner part of the two support frames 52. By providing the forward and reverse threaded rod 58, the two connecting plates 53 can be moved in opposite directions, which reduces the problem of unequal spacing between the connecting plates 53 due to the difficulty of the two connecting plates 53 moving in opposite directions at the same speed when the device is in use.

[0023] Furthermore, both ends of the forward and reverse threaded rod 58 are fixedly connected with positioning blocks 59, and one end of the forward and reverse threaded rod 58 is fixedly connected with a motor 510. By providing the positioning blocks 59, the forward and reverse threaded rod 58 can be easily limited in rotation.

[0024] Furthermore, a connecting seat 511 is fixedly connected to the surface of the motor 510 , and the connecting seat 511 is fixedly connected to the side of the connecting frame 51 . The connecting seat 511 is provided to facilitate limiting the position of the motor 510 .

[0025] In this embodiment, a connecting device 6 is provided at the lower end of the extrusion head 2, and the connecting device 6 includes a fixed block 61 and a connecting groove 62. The fixed block 61 is fixedly connected to the lower end of the extrusion head 2, and the connecting groove 62 is opened on the side of the fixed block 61. The connecting frame 51 is clamped inside the connecting groove 62. A pressure hole 63 is opened inside the end of the connecting frame 51 close to the fixed block 61, and a clamping groove 64 is opened inside the connecting groove 62. The inner wall of the pressure hole 63 is slidably connected to a pressure rod 67.

[0026] By providing the connection groove 62 , the connection frame 51 can be limited, thereby reducing the difficulty in positioning the connection frame 51 when the device is in use.

[0027] Furthermore, one end of the pressure rod 67 is fixedly connected to a clamping plate 65 , and one end of the clamping plate 65 is clamped with the inside of the clamping slot 64 . The clamping plate 65 is provided to facilitate limiting the connection frame 51 .

[0028] Furthermore, one end of the card plate 65 away from the card slot 64 is fixedly connected with a spring 66, and one end of the spring 66 away from the card plate 65 is fixedly connected to the inside of the pressure hole 63. The spring 66 is provided to facilitate the application of a reset elastic force to the card plate 65. The working principle of the utility model is as follows: the mounting plate 1 is placed at the discharge port of the equipment to be extruded, and then the mounting plate 1 is installed and connected by bolts, and then the equipment is operated, and the pipe material is discharged through the extrusion port 3. Before using the equipment, the user starts the motor 510, and then the rotation of the motor 510 drives the forward and reverse threaded rods 58 to rotate, and then the rotation of the forward and reverse threaded rods 58 drives the connecting plate 53 to move, and then the connecting plate 53 drives the support plate 54 to move, and when the connecting plate 53 moves, it drives the limit rod 55 to move, and then the limit rod 55 moves inside the support frame 52 and adjusts the opening of the support plate 54. By setting the support device 5, the material extruded from the inside of the extrusion head 2 is effectively supported, which plays a role in supporting the material. When the equipment extrude the material to form a pipe discharge, the newly extruded pipe is easily affected by its own gravity and falls, causing the pipe to shrink inward, affecting the finished product of the pipe, and causing the pipe to have different shapes. The support device 5 can effectively support the material just out of the equipment, play a role in preliminary shaping, and improve the practicality of the equipment.

[0029] When the device moves the connecting frame 51, the user presses the pressure rod 67, and the pressure rod 67 moves, which drives the card plate 65 to move. When the card plate 65 moves, it drives the spring 66 to displace and deform to generate elastic force, and the card plate 65 moves out of the inside of the card slot 64. Then the connecting frame 51 loses its restraint, and the user pulls the connecting frame 51 to move out of the inside of the connecting slot 62. By setting the connecting device 6, the connecting frame 51 is effectively connected to the extrusion head 2, which plays a role in quickly installing and connecting the connecting frame 51. When the device installs the connecting frame 51, bolts are generally used for installation and fixing. The installation and removal of the bolts require tools to operate. The use of tools is too cumbersome and easily causes low work efficiency of the user. The connecting device 6 can quickly install and connect the connecting frame 51, thereby improving the practicality of the equipment.
