An injection molding machine for processing automotive trim parts

Abstract

This utility model discloses an injection molding machine for processing automotive trim parts, including a base, a driver, a fixed frame, a connecting shaft, a barrel, a screw, an injection head, and a coupling structure. When the connecting shaft and screw are connected, both are aligned with the inside of the connecting barrel. Then, the screw is rotated, and a clamping plate presses down on the surface of the mounting block. At this time, a limiting rod is inserted into the mounting block, thereby fixing the connecting shaft and screw inside the connecting barrel, achieving convenient installation. The connection is simple and convenient. The transmission block is connected to the fixed groove and can be used for transmission, preventing stress on the screw. During disassembly, rotating the screw moves the clamping plate, causing the limiting rod to move out of the mounting block, thereby releasing the limiting installation on the connecting shaft and screw, achieving convenient disassembly and facilitating subsequent disassembly and maintenance of the extruder.

[0005] The purpose of this invention is to provide an injection molding machine for processing automotive trim parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an injection molding machine for processing automotive trim parts, comprising a base, a driver mounted on the base, a fixed frame at the end of the driver, a connecting shaft mounted on the driver, a barrel fixed on the base, a screw inside the barrel, an injection head at the end of the barrel, a coupling structure on the connecting shaft, the coupling structure including a fixing groove, fixing grooves at the mating ends of the connecting shaft and the screw, mounting blocks at the mating ends of the connecting shaft and the screw, a connecting cylinder mounted on the connecting shaft, a transmission block inside the connecting cylinder, a fixed seat fixed inside the connecting cylinder, a screw mounted in the fixed seat, a clamping plate on the screw, a limit rod on the surface of the clamping plate, and the limit rod being able to engage with the mounting block.

[0007] Preferably, at least two fixing grooves are provided, and they are symmetrically opened on the mating ends of the connecting shaft and the screw.

[0008] Preferably, the number of transmission blocks is the same as the number of fixed slots, and they are symmetrically arranged inside the connecting cylinder, with the positions of the transmission blocks corresponding to those of the screw.

[0009] Preferably, the transmission blocks arranged symmetrically have different heights, and the height of the fixing groove is adapted to the transmission blocks.

[0010] Preferably, the screw is a positive and negative screw, and both ends of the positive and negative screw are provided with a clamping plate, and the two clamping plates have the same structure.

[0011] Preferably, one side surface of the card plate is flat, and the card plate can be pressed against the surface of the mounting block under the action of the screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When connecting the connecting shaft and the screw, both the connecting shaft and the screw are aligned with the inside of the connecting cylinder. Then, the screw is rotated, and the clamping plate presses down on the surface of the mounting block. At this time, the limiting rod is inserted into the mounting block, thereby fixing the connecting shaft and the screw inside the connecting cylinder. This achieves the connection between the connecting shaft and the screw, providing a convenient installation. The connection is simple and convenient. The transmission block is connected to the fixed groove and can be used for transmission, preventing the screw from being stressed. During disassembly, rotating the screw moves the clamping plate and the limiting rod out of the mounting block, thereby releasing the limiting installation on the connecting shaft and the screw, achieving a convenient disassembly and facilitating subsequent disassembly and maintenance of the extruder.

Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an injection molding machine for processing automotive trim parts, including a base 1, a driver 2 on the base 1, a fixed frame 3 installed at the end of the driver 2, a connecting shaft 4 on the driver 2, a barrel 5 fixed on the base 1, a screw 6 inside the barrel 5, the mating ends of the connecting shaft 4 and the screw 6 are both located inside the fixed frame 3, an injection head 7 is provided at the end of the barrel 5, and a coupling structure 8 is provided on the connecting shaft 4.

[0017] Specifically, the raw material for automotive trim enters the barrel 5 through the feed tube. The driver 2 is turned on, causing the connecting shaft 4 to rotate through the coupling structure 8. The rotating screw 6 can pull and push the raw material, moving it inside the barrel 5, and then injecting it into the automotive trim mold through the injection head 7.

[0018] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides an injection molding machine for processing automotive trim parts. The coupling structure 8 includes a fixing groove 81. The connecting shaft 4 and the screw 6 are both provided with fixing grooves 81. There are at least two fixing grooves 81, which are symmetrically provided on the connecting shaft 4 and the screw 6. Of course, there can also be four, six, etc., without limitation. The connecting shaft 4 and the screw 6 are both integrally formed with mounting blocks 82. A connecting cylinder 83 is sleeved on the connecting shaft 4. The connecting cylinder 83 is integrally formed with transmission blocks 84. The number of transmission blocks 84 is the same as the number of fixing grooves 81. The heights of the transmission blocks 84 at the upper and lower ends are different. The positions of the transmission blocks 84 with different heights correspond to the screws 86 provided inside the connecting cylinder 83 to facilitate alignment and docking.

[0019] The connecting cylinder 83 has an integrally formed fixed seat 85 inside, and the fixed seat 85 is equipped with a rotating connecting screw 86. The screw 86 is a positive and negative screw, and both ends of the screw 86 are threadedly connected to a clamping plate 87. One side surface of the clamping plate 87 is flat, and a limit rod 88 is integrally formed on the surface of the clamping plate 87. The limit rod 88 can be connected to the mounting block 82.

[0020] Specifically, when connecting shaft 4 and screw 6 are connected, connecting sleeve 83 is sleeved on connecting shaft 4, so that transmission block 84 is aligned with fixing groove 81 on connecting shaft 4. After transmission block 84 of the same length is aligned with the matching fixing groove 81, mounting block 82 is aligned with limiting rod 88. Then, screw 6 is inserted into connecting sleeve 83, so that transmission block 84 is inserted into fixing groove 81. Then, screw 86 is rotated. Since clamping plate 87 is threadedly connected to screw 86, when screw 86 rotates, clamping plate 87 presses down on the surface of mounting block 82. At this time, the limiting rod 88 is closed. The positioning rod 88 is inserted into the mounting block 82, thereby fixing the connecting shaft 4 and the screw 6 inside the connecting cylinder 83, so as to connect the connecting shaft 4 and the screw 6, achieving the beneficial effect of convenient installation. Moreover, the connection is simple and convenient. The transmission block 84 is connected to the fixing groove 81 and can be used for transmission, avoiding the screw 86 from being stressed. When disassembling, the screw 86 is rotated, causing the clamping plate 87 to move and the limiting rod 88 to move out of the mounting block 82, thereby releasing the limiting installation of the connecting shaft 4 and the screw 6, achieving the beneficial effect of convenient disassembly, and facilitating the subsequent disassembly and maintenance of the extruder.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
