Description

Technical Field

[0001] This utility model belongs to the field of injection molding product technology, and is particularly related to an injection molding product part removal device. Background Technology

[0002] Currently, the injection molding industry commonly uses robotic arms connected to suction cups, relying on the negative pressure generated by the suction cups to lift the injection-molded product. However, this method is limited by the need for a relatively large flat surface on the product to ensure firm adhesion, and it is also time-consuming to adjust the suction cups. Figure 5 The injection mold 1 shown can form 4 rectangular injection products 101 with many concave surfaces after one injection. It is not easy to firmly adhere the parts when using a suction cup to pick them up. Usually, manual removal is used. Therefore, it is necessary to improve the mold and provide a part removal device to improve the part removal efficiency. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides an injection molded product removal device that can simultaneously remove four injection molded products formed on the injection mold, thereby improving removal efficiency.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A part-removing device for injection molded products, comprising:

[0006] A vertical plate with a pair of vertical grooves;

[0007] Two pairs of horizontal bars are arranged in a vertical array on the back side of the vertical plate. Each horizontal bar is connected to a pair of clamping plates via a pair of sliders on the side closest to the vertical plate. The clamping plates are located on the front side of the vertical plate. The pair of sliders are slidably connected to a pair of vertical grooves.

[0008] A pair of synchronizing mechanisms are respectively located between two pairs of crossbars. Each synchronizing mechanism includes a gear, a first rack, and a second rack. The gear is rotatably connected to the rear side of the vertical plate. The first rack is vertically connected to the upper crossbar of the pair of clamping plates, and the second rack is vertically connected to the lower crossbar of the pair of clamping plates. Both the first rack and the second rack are meshed with the gear.

[0009] A bidirectional pushing mechanism is located between two pairs of crossbars, used to drive the two crossbars closest to the middle of the vertical plate to move in opposite directions.

[0010] Furthermore, both pairs of crossbars are slidably connected to a pair of guide rods, and the pair of guide rods are fixed to the rear side of the vertical plate by a pair of second fixing plates.

[0011] Furthermore, the bidirectional pushing mechanism includes a push rod and a cylinder. The middle part of the push rod is rotatably connected to the rear side of the vertical plate, and the push rod is located between the two horizontal bars closest to the middle of the vertical plate. The fixed end of the cylinder is hinged to a connecting block, and the connecting block is connected to the rear side of the vertical plate. The telescopic end of the cylinder is hinged to the side of the push rod away from the vertical plate. When the telescopic end of the cylinder retracts, the two ends of the push rod respectively abut against the two horizontal bars closest to the middle of the vertical plate, and the two pairs of horizontal bars move towards each other until the spacing matches the length of the injection molded product to be removed. The two horizontal bars closest to the middle of the vertical plate are vertically connected to opposite sides, and the springs are fixed to the vertical plate by the first fixed plate. When the telescopic end of the cylinder extends, the two pairs of horizontal bars move in opposite directions until the spacing matches the length of the injection molded product to be removed.

[0012] Furthermore, there are two pairs of springs, each sleeved on one of the two guide rods.

[0013] Furthermore, each end of the push rod is rotatably connected to a roller, the axis of which is perpendicular to the vertical plate.

[0014] Furthermore, rubber gaskets are provided on the inner side of the clamps.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This device can simultaneously remove four injection molded products from the injection mold, improving the efficiency of product removal.

[0017] 2. When the cylinder extends, the spring is stretched, which pulls the two crossbars near the middle of the vertical plate to move towards each other. This causes the two pairs of crossbars to move in opposite directions until the distance between them matches the length of the injection molded product to be removed, thus preparing for the next part removal.

Detailed Implementation

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0025] This application provides a device for removing parts from injection-molded products, such as... Figures 1-4 As shown, it includes a vertical plate 2, a horizontal bar 3, a synchronization mechanism, a bidirectional pushing mechanism 5, etc.

[0026] Specifically, a pair of vertical grooves 201 are provided on the vertical plate 2; there are two pairs of horizontal bars 3, both arranged vertically on the rear side of the vertical plate 2. The side of each horizontal bar 3 closest to the vertical plate 2 is connected to a pair of clamping plates 302 via a pair of sliders 301. The clamping plates 302 are located on the front side of the vertical plate 2. The pair of sliders 301 are slidably connected to the pair of vertical grooves 201 respectively; a pair of synchronization mechanisms are respectively provided between the two pairs of horizontal bars 3. Each synchronization mechanism includes a gear 4, a first rack 401, and a second rack 402. The gear 4 is rotatably connected to the rear side of the vertical plate 2. The first rack 401 is perpendicularly connected to the upper horizontal bar 3 of the pair of horizontal bars 3. The second rack 402 is perpendicularly connected to the lower horizontal bar 3 of the pair of clamping plates 302. Both the first rack 401 and the second rack 402 are meshed with the gear 4; a bidirectional pushing mechanism 5 is provided between the two pairs of horizontal bars 3, used to drive the two horizontal bars 3 closest to the middle of the vertical plate 2 to move in opposite directions.

[0027] In actual use, the vertical plate 2 is connected to the robot arm. The robot arm drives the vertical plate 2 to move to the injection molded product 101 to be removed from the injection mold 1, so that the four injection molded products 101 are respectively between the four pairs of clamping plates 302. Then, the bidirectional pushing mechanism 5 is controlled to push the two horizontal bars 3 near the middle of the vertical plate 2 to move in the opposite direction. During this process, through the cooperation of the first rack 401, the gear 4, and the second rack 402, the other two horizontal bars 3 can move in the opposite direction synchronously, so that the four pairs of clamping plates 302 clamp the four injection molded products 101. Then, the robot arm is controlled to drive the vertical plate 2 to move away from the injection mold 1, so that the four injection molded products 101 can be removed at the same time.

[0028] For details, please refer to Figure 1Both pairs of horizontal bars 3 are slidably connected to a pair of guide rods 6, which are fixed to the rear side of the vertical plate 2 by a pair of second fixing plates 601. By setting the guide rods 6, the horizontal bars 3 can be prevented from shifting when moving up and down, thus improving their stability.

[0029] For details, please refer to Figure 4 The first rack 401 and the second rack 402 are slidably connected to a pair of slide rails 403 on the side away from the gear 4. The slide rails 403 are fixed to the rear side of the vertical plate 2 to improve the stability of the first rack 401 and the second rack 402 during movement.

[0030] For details, please refer to Figure 3 The bidirectional pushing mechanism 5 includes a push rod 501 and a cylinder 502. The middle part of the push rod 501 is rotatably connected to the rear side of the vertical plate 2, and the push rod 501 is located between the two horizontal bars 3 closest to the middle of the vertical plate 2. The fixed end of the cylinder 502 is hinged to a connecting block 5021, which is connected to the rear side of the vertical plate 2. The telescopic end of the cylinder 502 is hinged to the side of the push rod 501 away from the vertical plate 2. When the telescopic end of the cylinder 502 retracts, the two ends of the push rod 501 respectively abut against the two horizontal bars 3 closest to the middle of the vertical plate 2, and the two pairs of horizontal bars 3 move towards each other until the distance is equal to the distance between the two pairs of horizontal bars 3 and the injection molded product 101 to be removed. In terms of length matching, specifically, the thickness of the clamping plate 2 is set to match the thickness of the crossbar 3, and the clamping plate 2 and the crossbar 3 connected to it are at the same height. The two crossbars 3 closest to the middle of the vertical plate 2 are vertically connected to the opposite side of each other. The springs 7 are fixed to the vertical plate 2 by the first fixing plate 701. When the two crossbars 3 closest to the middle of the vertical plate 2 move in opposite directions and the telescopic end of the cylinder 502 is pushed out, the springs 7 are in a stretched state, which will pull the two crossbars 3 closest to the middle of the vertical plate 2 to move towards each other, so that the two pairs of crossbars 3 move in opposite directions until the distance is greater than the length matching of the injection molded product 101 to be taken out, in preparation for the next part removal.

[0031] For more details, please refer to Figure 1 There are two pairs of springs 7, each sleeved on one of the two guide rods 6. This allows the springs 7 to move along the guide rods 6 when stretched or contracted. Specifically, the inner side of the clamping plate 302 is provided with rubber pads to increase the friction when clamping the injection molded product 101 and prevent the injection molded product 101 from detaching from the clamping plate 302 during movement.

[0032] For details, please refer to Figure 3 Both ends of the push rod 501 are rotatably connected to a roller 5011. The axis of the roller 5011 is perpendicular to the vertical plate 2. When the push rod 501 rotates, the roller 5011 abuts against the crossbar 3, generating rolling friction. Compared with directly pushing the crossbar 3 through the push rod 501, the friction between the two can be reduced.

[0033] The above are only some of the embodiments listed in this application and are not intended to limit this application.
