Description

Technical Field

[0001] The invention belongs to the technical field of plastic processing, in particular to an injection molding device for processing plastic products. Background Art

[0002] Injection molding technology is a manufacturing process in which molten plastic material is injected into a mold through an injection molding machine and then molded into various plastic products after cooling. The principle of this technology is based on the thermoplasticity of plastic, that is, the plastic can soften and flow after heating, and cool and solidify after filling the mold to form a product of the desired shape. The working principle of the injection molding machine is similar to that of a syringe infusion. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (i.e., viscous flow state) of the plasticized plastic into the closed injection mold cavity at high pressure and speed. After cooling and solidification, the plastic product is almost the same shape as the mold cavity.

[0003] However, the existing injection molding equipment still has disadvantages in actual use: including but not limited to the following situations: 1. The injection quantity is controlled only by controlling the diameter of the spiral conveying tube and the number of its rotations. It is difficult to control when the injection quantity needs to be changed when changing the mold, and the calculation amount is large, which will cause a certain degree of waste of computing power; 2. Only a single set of molds can be injected at a time, and the injection molding efficiency is low; 3. The finished product cannot be quickly unloaded after injection molding, which reduces the efficiency of the injection molding process.

[0004] The device needs to be able to quickly perform quantitative injection when changing molds and prevent the mold and the plastic at the injection end from solidifying and sticking. It is necessary to improve the overall injection efficiency of the device by increasing the number of injections of the device, and quickly unload the raw materials after molding to improve the overall processing efficiency of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention cooperates with other structures such as the first cylinder, the electromagnetic limit block, and the stop block, so that when the first servo motor is started to drive the spiral conveying rod inside the spiral conveying cylinder to rotate and push the plastic raw material to move, the plastic raw material enters the interior of the quantitative box, and the flow meter can record the amount of plastic raw material passing through. After reaching the specified quality of the mold, a signal is sent to the first cylinder, and the first cylinder pushes the electromagnetic limit block and the stop block. At this time, the plastic raw material is continued to be pushed so that the stop block slides on the inner wall of the injection tube to isolate the plastic raw materials on both sides, and after the injection molding is completed through the injection molding tube, the support plate is rotated so that the group of injection ports is disconnected from the injection molding tube, and the spiral conveying rod is reversed at this time so that the stop block falls into the bottom end of the electromagnetic limit block, and the electromagnetic limit block is started to absorb the stop block, and the first cylinder pulls it up and measures it again, so as to achieve the purpose of facilitating the device to adjust the injection capacity of molds of different capacities and preventing the mold from being adhered to the plastic solidified at the injection molding end.

[0019] The present invention arranges a second servo motor, a rotating shaft, a transmission disk and other structures to cooperate, so that the device can start the second servo motor, and the second servo motor drives the rotating shaft to rotate, so that the rotating shaft can drive the transmission disk to rotate through its own shape and rotation trajectory during rotation, and the transmission disk can only rotate forty-five degrees when the rotating shaft rotates one circle.

[0020] The present invention cooperates with structures such as a connecting seat, a second cylinder, and a slider to enable the device to inject the injection molded mother part and the injection molded sub-part through the injection molding tube. When the injection molded mother part and the injection molded sub-part move to the bottom end after the injection molding is completed, the second cylinder contracts and pulls the flip plate to rotate the flip plate to a horizontal state. At this time, the injection molded mother part and the injection molded sub-part can be separated, and then the injection molded plastic product can be taken out. After the injection molded mother part and the injection molded sub-part are reset, the second cylinder retracts and pushes the flip plate to make its angle parallel to the connecting disk. At this time, when the injection molded mother part contacts the support disk and is connected to the injection molding port, the limit spring and the damper can buffer it to prevent the injection molded mother part from being damaged, thereby achieving the purpose of facilitating the device to take out and unload the mold after the injection molding is completed.

[0021] The present invention cooperates with other structures such as the third cylinder, the material-picking plate, and the suction cup, so that the device can start the third cylinder to push the material-picking plate to move upward and contact the injection molded sub-part when the flip plate completes the flipping of the injection port of the injection molded sub-part and is located below. The suction cup sucks it up, so that the injection molded sub-part is separated from the connection with the injection molded mother part and moves downward. At this time, the position of the nozzle is located at the injection port of the injection molded sub-part. The nozzle is used to blow air to the injection molded sub-part, so that the plastic product after injection molding can be discharged. After the discharge is completed, the injection molded sub-part is returned to its position and connected to the injection molded mother part, so as to achieve the purpose of facilitating the device to automatically unload the mold after injection molding.

[0037] The above solution is adopted: by starting the second servo motor 601, the second servo motor 601 drives the rotating shaft 602 to rotate, so that the rotating shaft 602 can drive the transmission disk 603 to rotate through its own shape and rotation trajectory during rotation, and the rotating shaft 602 rotates one circle, and the transmission disk 603 can only rotate forty-five degrees. By controlling the rotation speed of the rotating shaft 602, the time for the device to inject the injection ports 9 at different positions is guaranteed.

The connecting seat 1101 is fixed to the side wall of the connecting disk 10. The outer wall of the connecting seat 1101 is hinged with the second cylinder 1102. The top of the second cylinder 1102 is hinged with the slider 1103. The outer wall of the slider 1103 is provided with a flip plate 1104. The bottom end of the flip plate 1104 is fixed with a limit spring 1105. The bottom end of the flip plate 1104 is fixed with a damper 1106. The top of the damper 1106 is fixed with an injection molding mother part 1107. An injection molding sub-component 1108 is installed at the top of the mother component 1107, and four groups of second cylinders 1102 are provided. The second cylinders 1102 are arranged at equal intervals about the central axis of the connecting seat 1101. The outer wall of the slider 1103 is close to the inner wall of the flip plate 1104. The slider 1103 and the flip plate 1104 are slidingly connected. Two groups of limit springs 1105 are provided.

The top of the picking plate 1202 is installed with a suction cup 1203. The top of the picking plate 1202 is installed with a nozzle 1204. Four groups of suction cups 1203 are provided, and the suction cups 1203 are arranged at equal intervals about the central axis of the picking plate 1202.

[0042] The above scheme is adopted: when the flip plate 1104 completes the flipping of the injection molding sub-component 1108 and the injection port is located below, the third cylinder 1201 is started to push the material picking plate 1202 to move upward and contact the injection molding sub-component 1108, and it is sucked by the suction cup 1203, so that the injection molding sub-component 1108 is separated from the connection with the injection molding mother component 1107 and moves downward. At this time, the position of the nozzle head 1204 is located at the injection port of the injection molding sub-component 1108. The injection molding sub-component 1108 is blown by the nozzle head 1204 to discharge the injection molded plastic product. After the discharge is completed, the injection molding sub-component 1108 is returned to its position and connected to the injection molding mother component 1107.

After reaching the specified quality of the mold, a signal is sent to the first cylinder 501, and the first cylinder 501 pushes the electromagnetic limit block 502 and the stop block 503. At this time, the plastic raw material is continued to be pushed so that the stop block 503 slides on the inner wall of the injection tube 14 to isolate the plastic raw materials on both sides. After the injection is completed through the injection tube 14, the support plate 8 is rotated to disconnect the group of injection ports 9 from the injection tube 14. At this time, the reverse The spiral conveying rod causes the stop block 503 to fall into the bottom end of the electromagnetic limit block 502, and the electromagnetic limit block 502 is started to absorb the stop block 503. The first cylinder 501 pulls it up and performs metering again. By starting the second servo motor 601, the second servo motor 601 drives the rotating shaft 602 to rotate, so that the rotating shaft 602 can drive the transmission disk 603 to rotate through its own shape and rotation trajectory during rotation. Moreover, when the rotating shaft 602 rotates one circle, the transmission disk 603 can only rotate forty-five degrees. By controlling the speed of the rotating shaft 602, the time for the device to perform injection molding on the injection ports 9 at different positions is guaranteed, and the injection molding mother component 1107 and the injection molding sub-component 1108 are injected through the injection molding tube 14. After the injection molding is completed, when the injection molding mother part 1107 and the injection molding sub-part 1108 move to the bottom end, the second cylinder 1102 contracts and pulls the flip plate 1104, so that the flip plate 1104 rotates to a horizontal state. At this time, the injection molding mother part 1107 and the injection molding sub-part 1108 can be separated, and then the injection molded plastic product can be taken out. After the injection molding mother part 1107 and the injection molding sub-part 1108 are reset, the second cylinder 1102 is extended and retracted to push the flip plate 1104 so that its angle is parallel to the connecting disk 10. At this time, when the injection molding mother part 1107 contacts the support disk 8 and is connected to the injection port 9, the limit spring 1105 and the damper 1106 can be used for it. Buffering is performed to prevent damage to the injection molding mother component 1107. When the flip plate 1104 completes the flipping of the injection molding sub-component 1108 and the injection port is located below, the third cylinder 1201 is started to push the material picking plate 1202 to move upward and contact the injection molding sub-component 1108. The suction cup 1203 sucks it, so that the injection molding sub-component 1108 is separated from the connection with the injection molding mother component 1107 and moves downward. At this time, the position of the nozzle head 1204 is located at the injection port of the injection molding sub-component 1108. The injection molding sub-component 1108 is blown by the nozzle head 1204 to discharge the injection molded plastic product. After the discharge is completed, the injection molding sub-component 1108 is returned to its position and connected to the injection molding mother component 1107.
