Description

Technical Field

[0001] This utility model relates to the field of gate part processing technology, and in particular to a gate part post-processing device. Background Technology

[0002] The gate is a key component in mold design used to connect the runner and the cavity. Its main function is to control the flow of molten material into the cavity.

[0003] With the increasing demands on precision injection molded parts, higher requirements are placed on the level of foreign matter in injection molded parts. Common problems with point gate molds include gate protrusion, stringing, and burrs, making it difficult to meet high cleanliness requirements. Improving the cleanliness of the gate part ports can effectively improve the mechanical life. However, when cleaning the gate part ports, the different radii of the gate part ports make it impossible for the friction parts used for cleaning to fit tightly with the different sized gate part ports, thus making it impossible to clean the gate part ports of different sizes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where different radii of gate parts result in friction components used for cleaning not being able to fit tightly with gate parts of different sizes, thus making it impossible to clean gate parts of different sizes. Therefore, this invention proposes a gate part post-processing device.

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

[0006] Design a post-processing device for gated parts, including a base plate, a slide frame fixedly connected to the upper end of the base plate, a movable plate slidably connected to the slide frame, a motor fixedly connected to the upper end of the movable plate, the output end of the motor passing through the movable plate and fixedly connected to a groove frame, a bidirectional screw rotatably connected inside the groove frame, and two symmetrically arranged groove plates slidably connected inside the groove frame, each groove plate having a threaded hole, the bidirectional screw engaging with the threaded hole, and a friction mechanism connected to the bottom end of each groove plate via a fixing bolt.

[0007] Preferably, the friction mechanism includes an arc block, the arc block is connected to the groove plate by the fixing bolt, a fixing plate is connected to the arc surface of the arc block, a movable groove is provided on the fixing plate, a first friction plate is slidably connected to the movable groove, a spring is fixedly connected to the first friction plate, and one end of the spring is fixedly connected to the fixing plate.

[0008] Preferably, a second friction plate is fixedly connected to the first friction plate, and the second friction plate is slidably inserted into the arc block.

[0009] Preferably, a limiting mechanism is rotatably connected to the first friction plate. The limiting mechanism includes a pull rod, one end of which is rotatably connected to the first friction plate, and the other end of which passes through the fixed plate and is fixedly connected to the limiting plate. A support plate is fixedly connected to the fixed plate.

[0010] Preferably, the pull rod is arranged parallel to the support plate, and the limiting plate is in contact with the support plate.

[0011] The post-processing device for gated parts proposed in this utility model has the following advantages:

[0012] By rotating the bidirectional screw, the two groove plates move under the limit of the groove frame. Each groove plate drives the friction mechanism to move. The distance between the two friction mechanisms can be adjusted according to the size of the port radius of the gate part, so that the friction mechanism can be in close contact with the port of the gate part, which is convenient for cleaning gate parts of different sizes.

[0018] 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.

[0019] Example 1: Refer to Figure 1-3 A post-processing device for gated parts includes a base plate 1, a support platform 2 fixedly connected to the upper end of the base plate 1, a slide frame 3 fixedly connected to the upper end of the base plate 1, a movable plate 6 slidably connected to the slide frame 3, an electric telescopic rod 4 for driving the movable plate 6 to move vertically fixedly connected to the upper end of the slide frame 3, a motor 5 fixedly connected to the upper end of the movable plate 6, the output end of the motor 5 passing through the movable plate 6 and fixedly connected to a groove frame 7, a bidirectional screw 8 rotatably connected inside the groove frame 7, two symmetrically arranged groove plates 9 slidably connected inside the groove frame 7, each groove plate 9 having a threaded hole, the bidirectional screw 8 cooperating with the threaded hole, and a friction mechanism 10 connected to the bottom end of each groove plate 9 by a fixing bolt.

[0020] Work process:

[0021] The gate part is placed on the support platform 2 and fixed. The bidirectional screw 8 is rotated. After the bidirectional screw 8 rotates, the two groove plates 9 move towards each other under the limit of the groove frame 7. Each groove plate 9 drives the friction mechanism 10 to move, reducing the distance between the two friction mechanisms 10. After the electric telescopic rod 4 is powered on, it drives the movable plate 6 to move downward by a set distance. The movable plate 6 drives the groove frame 7 to move downward. The groove frame 7 drives the groove plate 9 to move through the bidirectional screw 8. The groove plate 9 drives the friction mechanism 10 to move, so that the friction mechanism 10 is located inside the port of the gate part.

[0022] Then rotate the bidirectional screw 8. After the bidirectional screw 8 rotates, the two groove plates 9 move in opposite directions under the limit of the groove frame 7. Each groove plate 9 drives the friction mechanism 10 to move, so that the two friction mechanisms 10 are in close contact with the port of the gate part. The distance between the two friction mechanisms 10 can be adjusted according to the radius of the port of the gate part, so that the friction mechanism 10 is in close contact with the port of the gate part, which is convenient for cleaning gate parts of different sizes.

[0023] After the motor 5 is powered on and started, it drives the groove frame 7 to rotate, which in turn drives the friction mechanism 10 to rotate. After the friction mechanism 10 rotates, it performs friction cleaning on the port of the gate part and cleans the adhesive on the port of the gate part.

[0024] Example 2: In Example 1, when the friction mechanism 10 cleans the port of the gate component, it cannot effectively clean the outer wall of the gate component port, thus reducing the cleaning effect. (Refer to...) Figure 2As another preferred embodiment of this utility model, the difference from embodiment 1 is that the friction mechanism 10 includes an arc block 101, the arc block 101 is connected to the groove plate 9 by a fixing bolt, a fixing plate 102 is connected to the arc surface of the arc block 101, a movable groove 103 is provided on the fixing plate 102, a first friction plate 104 is slidably connected to the movable groove 103, a spring 106 is fixedly connected to the first friction plate 104, one end of the spring 106 is fixedly connected to the fixing plate 102, a second friction plate 105 is fixedly connected to the first friction plate 104, and the second friction plate 105 is slidably inserted into the arc block 101;

[0025] The inner wall of the gate component port is in contact with the arc surface of the arc block 101. The first friction plate 104 is in close contact with the outer wall of the gate component port under the elastic force of the spring 106. The lower surface of the second friction plate 105 is in close contact with the upper end of the gate component port. During the rotation of the arc block 101, the first friction plate 104 is driven to rotate through the fixed plate 102. After the first friction plate 104 rotates, it rubs and cleans the outer wall of the gate component port. The first friction plate 104 drives the second friction plate 105 to rotate. After the second friction plate 105 rotates, it cleans the upper end of the gate component port, thereby improving the cleaning effect of the gate component port.

[0026] Example 3: In Example 2, initially, the gap between the first friction plate 104 and the arc block 101 is small, so when the groove frame 7 moves downward, the upper end of the gate part port cannot be inserted into the gap between the first friction plate 104 and the arc block 101. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 2 is that a limiting mechanism 11 is rotatably connected to the first friction plate 104. The limiting mechanism 11 includes a pull rod 111. One end of the pull rod 111 is rotatably connected to the first friction plate 104, and the other end of the pull rod 111 passes through the fixing plate 102 and is fixedly connected to the limiting plate 112. A support plate 113 is fixedly connected to the fixing plate 102. The pull rod 111 and the support plate 113 are arranged parallel to each other, and the limiting plate 112 is in contact with the support plate 113.

[0027] Initially, the limiting plate 112 is pulled outward, the limiting plate 112 pulls the pull rod 111, the pull rod 111 pulls the first friction plate 104, and after the first friction plate 104 moves, the distance between it and the arc block 101 increases, making it easier for the upper end of the gate part port to be inserted into the gap between the first friction plate 104 and the arc block 101.

[0028] Simultaneously, the first friction plate 104 moves and compresses the spring 106. The spring 106 generates elastic force after being compressed, and rotates the limiting plate 112. The limiting plate 112 contacts the support plate 113, and the support plate 113 limits the limiting plate 112, keeping the spring 106 in a compressed state. After inserting the first friction plate 104 into the gap between the arc block 101 at the upper end of the gate part port, the limiting plate 112 is rotated, and the limiting plate 112 is misaligned with the support plate 113. Under the elastic force of the spring 106, the first friction plate 104 is driven to move and reset, so that the first friction plate 104 tightly presses the outer wall of the gate part port.

[0029] 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.
