Description

Technical Field

[0001] This utility model relates to the field of demolding device technology, specifically a demolding device for injection molded parts. Background Technology

[0002] The choice of plastic parts mainly depends on the type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Injection molding is generally carried out by compression molding, transfer molding, and injection molding. Lamination, compression molding, and thermoforming are methods to shape plastic on a plane. All of the above methods can be used for rubber processing. In addition, there are casting methods using liquid monomers or polymers as raw materials. Among these methods, extrusion and injection molding are the most commonly used and are the most basic molding methods. The production process of injection molded parts requires the use of molds. After the injection molded parts cool, they need to be demolded, which requires the use of demolding devices.

[0003] Existing injection molding demolding devices are not convenient for demolding and unloading during the injection molding process. Demolding and unloading must be performed after the injection molding is completed, which reduces work efficiency.

[0004] Based on this, a demolding device for injection molded parts is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a demolding device for injection molded parts, so as to solve the problem in the prior art that it is inconvenient to perform demolding and unloading operations at the same time as injection.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5 As shown, an injection molded part demolding device includes a base 1, a mounting seat 2 is fixedly installed on one side of the top of the base 1, a rotating mechanism 3 is provided on the top of the mounting seat 2, and a second fixing plate 7 is fixedly installed on the other side of the top of the base 1.

[0028] The top of the second fixed plate 7 is provided with a displacement mechanism 8, and the outside of the displacement mechanism 8 is provided with a feeding mechanism 9.

[0029] In this embodiment, the position of the injection mold 302 can be changed by rotating the rotating mechanism 3. After injection, the injection mold 302 rotates to the bottom of the unloading mechanism 9. The unloading mechanism 9 removes the injection part from the injection mold 302. Then, the displacement mechanism 8 drives the unloading mechanism 9 to move above the unloading plate 5 and places the injection part on the unloading plate 5. The unloading operation is completed by the unloading plate 5. The rotating mechanism 3 can perform unloading while injection, which improves work efficiency.

[0030] In one embodiment, such as Figure 2 As shown, the rotating mechanism 3 includes a rotating plate 301, which is rotatably mounted on the top of the mounting base 2. An injection mold 302 is fixedly mounted equidistantly in a ring on the top of the rotating plate 301. A first gear 303 is fixedly mounted at the center point of the bottom of the rotating plate 301. A second gear 304 is externally meshed with the first gear 303. A first motor 305 is fixedly mounted inside the mounting base 2, and the output end of the first motor 305 is connected to the second gear 304. The first motor 305 drives the second gear 304 to rotate. One rotation of the second gear 304 drives the first gear 303 to rotate 90°, thereby changing the position of the injection mold 302 on the top of the rotating plate 301. This facilitates moving the injection mold 302, after injection molding, to below the unloading mechanism 9, allowing for demolding and unloading simultaneously with injection molding, thus improving work efficiency.

[0031] In one embodiment, such as Figure 3 As shown, the displacement mechanism 8 includes a mounting strip 801, which is fixedly mounted on the top of the second fixed plate 7. A mounting groove 802 is provided on the outer side of the mounting strip 801. A second lead screw 803 is rotatably mounted inside the mounting groove 802. A third motor 804 is fixedly mounted on one end of the mounting strip 801, and the output end of the third motor 804 is connected to the second lead screw 803. A moving plate 805 is threadedly connected to the outer side of the second lead screw 803. The third motor 804 drives the second lead screw 803 to rotate, and the rotation of the second lead screw 803 drives the moving plate 805, thereby changing the position of the feeding mechanism 9.

[0032] In one embodiment, such as Figure 3As shown, the unloading mechanism 9 includes a cylinder 901, which is fixedly installed on the outer side of the moving plate 805. A lifting plate 902 is fixedly installed at the output end of the cylinder 901. An air pump 903 is symmetrically fixedly installed on the top of the lifting plate 902, and a suction cup 904 is symmetrically fixedly installed on the bottom of the lifting plate 902. The air pump 903 is connected to the suction cup 904. When the unloading mechanism 9 moves directly below the injection mold 302, the lifting plate is driven by the operation of the cylinder 901. 902 moves downward, causing the suction cup 904 to contact the injection molded part. The air pump 903 works to give the suction cup 904 suction force, fixing the injection molded part to the suction cup 904. The cylinder 901 retracts, causing the lifting plate 902 to move upward, thereby sucking out the injection molded part and demolding it. Then, the third motor 804 rotates in the opposite direction, causing the moving plate 805 to move the cylinder 901 to directly below the unloading plate 5. The air pump 903 stops working, and the injection molded part falls onto the surface of the unloading plate 5 due to gravity, completing the unloading operation.

[0033] In one embodiment, such as Figure 4 As shown, a first fixing plate 4 is fixedly installed on the top of the base 1 and between the second fixing plate 7 and the mounting base 2. A material feed plate 5 is rotatably installed on the outer side of the first fixing plate 4. The material feed plate 5 is used to feed the injection molded part, and the angle of the material feed plate 5 can be adjusted for easy use according to requirements.

[0034] In one embodiment, such as Figure 4 As shown, the bottom of the feeding plate 5 is provided with an adjustment mechanism 6, which can adjust the angle of the feeding plate 5.

[0035] In one embodiment, such as Figure 5 As shown, the adjustment mechanism 6 includes a second fixed seat 608 and two mounting plates 601. The second fixed seat 608 is symmetrically fixedly installed at the bottom of the feed plate 5. A connecting rod 607 is rotatably installed inside the second fixed seat 608. A first fixed seat 606 is rotatably installed at one end of the connecting rod 607. When the moving seat 604 moves, the angle of the feed plate 5 is changed through the cooperation of the first fixed seat 606, the connecting rod 607 and the second fixed seat 608.

[0036] In one embodiment, such as Figure 5As shown, both mounting plates 601 are fixedly mounted on the top of the base 1. A first lead screw 602 is rotatably mounted between the two mounting plates 601. A second motor 603 is fixedly mounted on the outside of one of the mounting plates 601, and the output end of the second motor 603 is connected to the first lead screw 602. A movable seat 604 is threadedly connected to the outside of the first lead screw 602. A first fixed seat 606 is fixedly mounted to the movable seat 604. A limit rod 605 is fixedly mounted between the two mounting plates 601. The movable seat 604 and the limit rod 605 are slidably mounted. The second motor 603 drives the first lead screw 602 to rotate, and the rotation of the first lead screw 602 drives the movable seat 604 to move. The setting of the limit rod 605 improves the stability of the movement of the movable seat 604.

[0037] The above embodiments disclose a demolding device for injection molded parts. A first motor 305 drives a second gear 304 to rotate. One rotation of the second gear 304 causes the first gear 303 to rotate 90°, thereby changing the position of the injection mold 302 at the top of the rotating plate 301. This facilitates moving the completed injection mold 302 below the unloading mechanism 9, allowing for demolding and unloading simultaneously with injection molding, improving work efficiency. A third motor 804 drives a second lead screw 803 to rotate. The rotation of the second lead screw 803 drives a moving plate 805, thereby changing the position of the unloading mechanism 9. When the unloading mechanism 9 moves directly below the injection mold 302, the cylinder 901 drives the lifting plate 902 to move downward, so that the suction cup 904 contacts the injection part. The air pump 903 works to make the suction cup 904 have suction force, so that the injection part is fixed to the suction cup 904. The cylinder 901 retracts to drive the lifting plate 902 to move upward, thereby sucking out the injection part and demolding it. Then, the third motor 804 rotates in the opposite direction, so that the moving plate 805 drives the cylinder 901 to move directly below the unloading plate 5. The air pump 903 stops working, and the injection part falls onto the surface of the unloading plate 5 due to gravity, completing the unloading operation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
