Description

Technical Field

[0002] An injection molding machine, also known as an injection molding machine or injection molding machine, is a primary molding device that uses plastic molds to create various shapes of plastic products from thermoplastic or thermosetting plastics. After the injection molding machine completes the injection molding process, the product needs to be removed to complete the unloading operation.

[0017] Example 1

[0018] like Figures 1 to 3 As shown, this utility model proposes an automatic material handling device for an injection molding machine, including a vertical moving mechanism 1, a material handling mechanism, and a stabilizing mechanism. A horizontal moving mechanism 101 is driven and connected to the vertical moving mechanism 1, and a connecting seat 102 is driven and connected to the horizontal moving mechanism 101. The connecting seat 102 is adjusted horizontally by the drive of the horizontal moving mechanism 101, and also adjusted vertically by the drive of the horizontal moving mechanism 101. Both the horizontal moving mechanism 101 and the connecting seat 102 are existing technologies and will not be described in detail further. The material handling mechanism is driven by a driving mechanism installed at the bottom of the connecting seat 102. The material gripping mechanism is rotatably connected to the connecting seat 102. It consists of a mounting box 2 rotatably connected to the connecting seat 102, multiple sets of adjusting tubes 4 slidably connected along the height direction of the mounting box 2, and a vacuum suction cup 403 installed at the bottom of the adjusting tubes 4. The top of the adjusting tubes 4 extends to the outside of the top of the mounting box 2 and is connected to a vacuum tube 404. The vacuum tube 404 is connected to an external vacuum device. A spring 402 is sleeved on the outside of the adjusting tubes 4. The bottom of the spring 402 is connected to the bottom of the adjusting tubes 4, and the top of the spring 402 is connected to the bottom of the mounting box 2. The stabilizing mechanism is set inside the mounting box 2, and the output end of the stabilizing mechanism abuts against the adjusting tubes 4.

[0019] Furthermore, a cover plate 201 is bolted to the top of the mounting box 2, and a rotating seat 202 is mounted on the top of the cover plate 201. Two sets of rotating shafts are symmetrically mounted on the rotating seat 202, and the rotating shafts are rotatably connected to the connecting seat 102. One set of rotating shafts is driven to rotate by a drive mechanism on the connecting seat 102. The cover plate 201 is detachably connected to the mounting box 2 by bolts, which facilitates the inspection and maintenance of the components inside the mounting box 2.

[0020] Furthermore, two sets of guide bars 401 are symmetrically installed on the side wall of the regulating tube 4. The guide bars 401 are slidably connected to the mounting box 2. The setting of the guide bars 401 ensures that the regulating tube 4 can only slide and adjust vertically along the mounting box 2, and cannot rotate along the mounting box 2, so as to avoid interfering with the vacuum adsorption material gripping.

[0021] In this embodiment, the vertical moving mechanism 1 is installed at a suitable position near the injection molding machine using bolts. The controller activates the horizontal moving mechanism 101 and the vertical moving mechanism 1, causing the connecting seat 102 to adjust, allowing the connecting seat 102 to move horizontally and vertically. Simultaneously, the drive mechanism activates the mounting box 2 to rotate at a suitable angle along the connecting seat 102, so that the mounting box 2 faces the plastic product. This, in turn, moves the material gripping mechanism to the vicinity of the injection-molded product, causing multiple sets of vacuum suction cups 403 to face the molded plastic product. The vertical moving mechanism 1 and the horizontal moving mechanism 101 continuously adjust and drive the multiple sets of vacuum suction cups 403. Approaching the plastic product, the external vacuum equipment is activated. Some vacuum suction cups 403 directly adhere to the plastic product, while others are pushed by the protruding parts on the plastic product, causing the adjusting tube 4 to slide horizontally along the mounting box 2, thereby compressing the spring 402 until multiple sets of vacuum suction cups 403 adhere to the plastic product. At this point, the controller activates the stabilizing mechanism to press the adjusting tube 4 against the plastic product, thus enabling stable adsorption and gripping of the plastic product. Through adjustments made by the vertical moving mechanism 1, the horizontal moving mechanism 101, and the drive mechanism, the gripped plastic product is removed from the injection molding machine. This allows for stable adsorption and gripping of plastic products of different shapes.

[0022] Example 2

[0023] like Figure 2 and Figure 3 As shown, the automatic material gripping device for injection molding machines proposed in this utility model, compared with Embodiment 1, includes a stabilizing mechanism comprising a drive assembly, a moving rod 303, and an abutment seat 304; the drive assembly is disposed inside the mounting box 2; multiple sets of moving rods 303 are provided, and the multiple sets of moving rods 303 are evenly distributed on the output end of the drive assembly. The multiple sets of moving rods 303 are driven by the drive assembly to move closer together or move further away to adjust. The moving rods 303 are slidably connected along the horizontal direction of the mounting box 2; the abutment seat 304 is installed on the moving rod 303 and at the end away from the drive assembly. The abutment seat 304 abuts against the corresponding adjusting tube 4. The abutment end of the abutment seat 304 is provided with an anti-slip protrusion 305 and an anti-slip plate. The side wall of the adjusting tube 4 is provided with an anti-slip groove. The anti-slip protrusion 305 is inserted into the anti-slip groove to improve the stability of the abutment seat 304 abutting against the adjusting tube 4 and prevent the adjusting tube 4 from easily sliding along the mounting box 2.

[0024] Furthermore, the drive assembly includes a drive bevel gear 3 and a threaded rod 301; the drive bevel gear 3 is driven to rotate by a motor mounted on the mounting box 2; multiple sets of threaded rods 301 are provided, and the multiple sets of threaded rods 301 are evenly rotatably connected to the mounting box 2. One end of the threaded rod 301 is equipped with a driven bevel gear 302, which meshes with the drive bevel gear 3, and the other end of the threaded rod 301 is threadedly connected to the moving rod 303.

[0025] Furthermore, multiple sets of guide grooves 307 are evenly provided at the bottom of the mounting box 2, and a guide seat 306 is installed at the bottom of the moving rod 303. The bottom of the guide seat 306 is slidably connected to the guide groove 307. The guide seat 306 is T-shaped, so that the moving rod 303 can be stably slidably adjusted along the horizontal direction of the mounting box 2.

[0026] In this embodiment, the controller drives the motor to drive the active bevel gear 3 to rotate, which in turn drives multiple sets of driven bevel gears 302 to rotate. Under the guidance of the guide seat 306, multiple sets of moving rods 303 move horizontally and spread outward, thereby driving the anti-slip protrusion 305 to press against the corresponding adjusting tube 4, thereby limiting the adjusting tube 4 on the mounting box 2, and cooperating with the vacuum suction cup 403 to stably adsorb the plastic product.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
