Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts processing technology, and in particular to a sprue cutting device. Background Technology
[0002] Injection molded products are a common type of structure, used in many places such as the housings of machinery and equipment, the housings of household appliances, and everyday consumer goods. During the injection molding process, the injection mold forms a sprue at the inlet, connecting to the product. The product is then injected into the mold in a single pass. Figure 1 When two symmetrical injection-molded products 1 facing opposite directions are shown, a sprue structure 2 is provided between the two symmetrical injection-molded products 1. Each injection-molded product 1 is equipped with a first support arm 101 and a second support arm 102, both of which have through-hole mounting holes. To meet subsequent processing requirements, after cutting the sprue structure between the two injection-molded products, one of the injection-molded products needs to be flipped so that its orientation matches that of the other injection-molded product. In this process, both the sprue cutting and the flipping of the injection-molded product are manual operations, resulting in low work efficiency. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This utility model provides a sprue cutting device. Two symmetrical, oppositely oriented injection molded products are positioned on a placement table via a first and second feeding position. A cutting and flipping unit drives a cutting head through a telescopic mechanism to cut off the sprue structure. After the sprue structure is cut off, a clamping mechanism holds the injection molded product located at the second feeding position. The first flipping mechanism drives the holding mechanism to flip from the second feeding position to the feeding position, thereby flipping the injection molded product on the clamping mechanism and positioning it at the feeding position. The distance between the feeding position and the first feeding position is adapted to the distance between the two gripping mechanisms, so that a multi-axis robot can move two injection molded products with the same orientation to the next processing step via the gripping mechanism. This eliminates the need for manual cutting of the sprue structure and manual flipping of the injection molded products, thus improving work efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

A multi-axis robot 4 is mounted on the frame 3. The operating end of the multi-axis robot 4 is equipped with a gripping component 5. The gripping component 5 includes a mounting plate 51 and two gripping mechanisms 52 that are spaced apart and symmetrically arranged on the mounting plate 51. The gripping mechanism 52 is a pneumatic gripper.
[0025] The placement unit 6 includes a first lifting mechanism 62 and a placement platform 61. The placement platform 61 is symmetrically provided with a first material placement position 7 and a second material placement position 8. The first material placement position 7 and the second material placement position 8 are respectively for placing two symmetrical injection molded products 1 facing different directions. The first material placement position 7 and the second material placement position 8 are both composed of two column structures. The top of one column structure is inserted into the mounting hole, and the other column structure is fitted into the bottom of the injection molded product 1. The first lifting mechanism 62 is a telescopic cylinder, and the lifting end of the first lifting mechanism 62 is connected to the placement platform 61.
[0026] The loading unit 9 includes a second lifting mechanism 92 and a loading platform 91. The loading platform 91 has a loading position 10 for placing the injection-molded product 1. The loading position 10 consists of two cylindrical structures, one of which has its top inserted into a mounting hole, and the other cylindrical structure fitting into the bottom of the injection-molded product 1. The distance between the loading position 10 and the first unloading position 7 is adapted to the distance between the two gripping mechanisms 52. The second lifting mechanism 92 is a telescopic cylinder, and its lifting end is connected to the loading platform 91.
[0027] The cutting and flipping unit 11 includes a mounting frame 111, a telescopic mechanism 112 and a first flipping mechanism 113 mounted on the mounting frame 111. The telescopic mechanism 112 is a telescopic cylinder. The telescopic end of the telescopic mechanism 112 is provided with a punching head 12 for cutting off the sprue structure 2. The punching head 12 is located between the first feeding position 7 and the second feeding position 8. The first flipping mechanism 113 is a flipping cylinder. The flipping end of the first flipping mechanism 113 is provided with a clamping mechanism 13 for clamping the injection molded product 1. The flipping end of the first flipping mechanism 113 is provided with a flipping plate 16. The clamping mechanism 13 is mounted on the flipping plate 16. The flipping plate 16 has a clearance groove 17 for the punching head 12 to pass through. When the clamping mechanism 13 moves from the first flipping mechanism 113 to above the second feeding position 8, the punching head 12 is located in the clearance groove 17.
[0028] The flipping and feeding unit 159 includes a second flipping mechanism 151, a transfer table 152, and a first positioning mechanism 153 and a second positioning mechanism 154 symmetrically arranged on the transfer table 152. The first positioning mechanism 153 and the second positioning mechanism 154 are both three-claw cylinders. The first positioning mechanism 153 and the second positioning mechanism 154 are respectively used to place and clamp two symmetrical injection molded products 1 facing different directions. The second flipping mechanism 151 is a flipping cylinder, and the flipping end of the second flipping mechanism 151 is connected to the transfer table 152.
[0029] When in use, the sprue cutting device can place two symmetrical injection molded products 1 facing opposite directions on the transfer table 152 or the placement table 61. The second flipping mechanism 151 flips the two injection molded products 1 on the transfer table 152 and feeds them onto the placement table 61. The two symmetrical injection molded products 1 facing opposite directions are positioned on the placement table 61 by the first feeding position 7 and the second feeding position 8. The cutting and flipping unit 11 drives the punching head 12 to cut off the sprue structure 2 through the telescopic mechanism 112. The frame 3 is provided with an upward-facing recycling hopper 14 at a position relative to the placement table 61. The punching head 12 and the recycling hopper 14 are arranged opposite to each other on the placement table 61. The opening of the recycling hopper 14 is located below the placement table 61 to collect the cut-off sprue structure 2.
[0030] After the sprue structure 2 is removed, the clamping mechanism 13 clamps the injection molded product 1 located on the second unloading position 8. The first flipping mechanism 113 drives the clamping mechanism to flip from the second unloading position 8 to the loading position 10, thereby positioning the injection molded product 1 on the clamping mechanism 13 in the loading position 10 after flipping. The distance between the loading position 10 and the adjacent first unloading position 7 is adapted to the distance between the two gripping mechanisms 52, so that the multi-axis robot 4 can move the two injection molded products 1 facing the same direction to the next processing step through the gripping mechanism 52 without manually removing the sprue structure 2 and manually flipping the injection molded product 1, thereby improving work efficiency.
[0031] Two opposing uprights 18 are mounted on the frame 3. Position sensors 19 are mounted on the top of each upright 18. A first lifting mechanism 62 and a second lifting mechanism 92 are electrically connected to the two position sensors 19. The sensing ends of the two position sensors 19 face the placement platform 61 and the loading platform 91, respectively, and are engaged with the placement platform 61 and the loading platform 91. Preferably, the position sensors 19 can be metal sensors, with metal sensors on opposite sides of the placement platform 61 and the loading platform 91. When the corresponding injection molded product 1 is placed in the loading position 10, the first lifting mechanism 62 and the second lifting mechanism 92 adjust the height of the placement platform 61 and the loading platform 91 until the opposite sides of the placement platform 61 and the loading platform 91 correspond to the sensing ends of the two position sensors 19. At this point, the two position sensors 19 are triggered to stop the first lifting mechanism 62 and the second lifting mechanism, ensuring that the two injection molded products 1 facing the same direction are at the same height, facilitating the gripping operation of the gripping mechanism 52.
