This solution collects multiple groups of plastic products after injection molding by adding a material collecting mechanism. Therefore, it not only greatly reduces the waste of manpower, but also improves the material collecting efficiency, thereby enhancing practicality.

[0004] This solution uses a push plate to push the product out of the mold cavity, and then blows the product away with an air gun to achieve simultaneous collection of multiple products. This setting has the following disadvantages: the product may adhere to the push plate during the injection molding process, and the air gun may not be able to blow the product off the push plate, and the airflow sprayed by the air gun should not be too large, otherwise it will easily cause the product to be blown away. Even if the product is blown off, the fallen product may be trapped between adjacent push plates, and it cannot be guaranteed that it can reach the position of the auxiliary plate. In summary, this solution has many uncertain factors in the product collection method and the collection effect is poor. Therefore, a multi-cavity material collecting equipment is proposed to address the above problems.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] like Figure 1-5As shown, the present application provides a multi-cavity material collecting device, including a base 1, a lower mold 2 is arranged on the upper side of the base 1, and a hydraulic rod 17 is installed on the base 1, the output end of the hydraulic rod 17 is fixedly connected to the lower mold 2, a plurality of mold cavities 3 are opened on the lower mold 2, and a plurality of limiting rods 11 are arranged on the lower side of the lower mold 2, the plurality of limiting rods 11 all pass through the bottom end of the lower mold 2 and extend to the interior of the plurality of mold cavities 3 respectively, the top end of the limiting rod 11 is slidably connected with an ejector rod 10, an electric push rod 4 is installed at one end of the base 1, the output end of the electric push rod 4 is fixedly connected with a mounting block 5, a servo motor 6 is installed at one end of the mounting block 5, the output end of the servo motor 6 is fixedly connected with a blanking plate 7, a plurality of positioning grooves 8 matching the ejector rod 10 are opened on the blanking plate 7, and a collecting box 9 is arranged on the lower side of the blanking plate 7, and the position of the positioning groove 8 corresponds to the position of the ejector rod 10.

[0029] The injection molding of plastic products often involves molding a large number of products at one time, especially smaller plastic products. In this case, a multi-cavity mold is required. After the injection molding is completed, multiple groups of plastic products need to be taken out of the multiple cavities.

[0030] In this scheme, an upper mold matching the lower mold 2 should also be provided. During the injection molding process, the upper mold and the lower mold 2 are molded together, and the molten material is injected into the inner cavity of the mold cavity 3 through the injection channel on the upper mold. The plastic product is molded in the inner cavity of the mold cavity 3. After molding, the upper mold is separated from the lower mold 2. At this time, the user starts the hydraulic rod 17 to drive the lower mold 2 to move downward, and the bottom ends of the multiple limit rods 11 abut against the top of the base 1 and then stop moving, while the lower mold 2 continues to move downward, causing the multiple limit rods 11 to drive the ejector rods 10 to eject the inner cavity of the mold cavity 3, thereby ejecting the product in the inner cavity of the mold cavity 3. Then the user starts the electric push The rod 4 drives the mounting block 5, the servo motor 6 and the blanking plate 7 to move. At this time, the blanking plate 7 and the multiple ejector rods 10 are at the same horizontal position. As the blanking plate 7 moves, the multiple positioning grooves 8 penetrate the multiple ejector rods 10, so that the blanking plate 7 comes to the lower side of the multiple products. Then the user starts the servo motor 6 to drive the blanking plate 7 to flip upward, so that the blanking plate 7 is tilted, so that the multiple products are lifted up by the tilting of the blanking plate 7, so that the products are separated from the ejector rods 10 and slide into the collection box 9 along the blanking plate 7 for collection. With this arrangement, all products can be collected at the same time and the success rate of product collection can be ensured.

[0031] The upper surface of the ejector rod 10 and the bottom end of the inner wall of the mold cavity 3 form a complete plane.

[0032] The upper surface of the ejector pin 10 and the bottom end of the inner wall of the mold cavity 3 form a complete plane, so that the molten material can be smoothly formed in the inner cavity of the mold cavity 3.

[0033] The outer end of the limiting rod 11 is sleeved with a first spring 12 , and two ends of the first spring 12 are fixedly connected to the limiting rod 11 and the bottom end of the lower mold 2 respectively.

[0034] When the mold cavity 3 moves downward and the limit rod 11 remains stationary, the first spring 12 will be squeezed. With this arrangement, when the mold cavity 3 is reset upward, under the elastic force of the first spring 12, multiple limit rods 11 and the ejector rod 10 will also be reset smoothly, ensuring that the ejector rod 10 is re-attached to the bottom end of the inner cavity of the mold cavity 3.

[0035] A pair of mutually symmetrical positioning posts 13 are fixedly connected to the bottom end of the lower mold 2 , and the pair of positioning posts 13 both penetrate the base 1 .

[0036] During the up and down movement of the lower mold 2 , a pair of positioning posts 13 slide on the base 1 . The arrangement of the pair of positioning posts 13 can ensure the stability of the lower mold 2 during the movement.

[0037] like Figure 6 As shown, the bottom end of the ejector rod 10 extends to the inner cavity of the limiting rod 11, and a pair of mutually symmetrical extrusion blocks 15 are integrally formed at the bottom of the outer end of the ejector rod 10. A pair of through holes 14 communicating with the inner cavity are opened at the bottom of the outer end of the limiting rod 11. The through holes 14 match the extrusion blocks 15. The extrusion blocks 15 pass through the through holes 14 and extend to the outside of the limiting rod 11. The ejector rod 10 is located on the outside of the inner cavity of the limiting rod 11 and is sleeved with a second spring 16. The two ends of the second spring 16 are fixedly connected to the inner wall of the limiting rod 11 and the ejector rod 10, respectively.

[0038] After the multiple ejector rods 10 completely eject the product out of the mold cavity 3, the blanking plate 7 will also come to the lower side of the product, and at this time the lower mold 2 is still moving downward. When the bottom end of the lower mold 2 abuts against the multiple extrusion blocks 15, the extrusion blocks 15 will be pushed to the lower side of the through hole 14, thereby driving the ejector rod 10 to move downward into the inner cavity of the limit rod 11 and stretching the second spring 16. Since the product is located on the upper side of the blanking plate 7 at this time, the downward movement of the ejector rod 10 will cause the ejector rod 10 to separate from the product, and the product will be trapped at the upper end of the blanking plate 7. This arrangement can further ensure that the product is completely separated from the ejector rod 10, avoiding adhesion between the product and the ejector rod 10. When the lower mold 2 is reset upward, the ejector rod 10 will be reset under the elastic force of the second spring 16.

[0039] Working principle:

[0040] After the molten material is injection molded in the mold cavity 3, the upper mold is separated from the lower mold 2, and the user starts the hydraulic rod 17 to drive the lower mold 2 to move downward. The bottom ends of the multiple limit rods 11 abut against the top of the base 1 and then stop moving, while the lower mold 2 continues to move downward, causing the multiple limit rods 11 to drive the ejector rods 10 to eject the inner cavity of the mold cavity 3, and then eject the product in the inner cavity of the mold cavity 3. At this time, the user starts the electric push rod 4 to drive the mounting block 5, the servo motor 6 and the blanking plate 7 to move. As the blanking plate 7 moves, the multiple positioning grooves 8 penetrate the multiple ejector rods 10, so that the blanking plate 7 comes to the lower side of the multiple products, and the lower mold The tool 2 continues to move downward. When the bottom end of the lower mold 2 abuts against the multiple extrusion blocks 15, the lower mold 2 pushes the extrusion blocks 15 to the lower side of the through hole 14, thereby driving the ejector rod 10 to move downward into the inner cavity of the limiting rod 11 and stretching the second spring 16. The downward movement of the ejector rod 10 will cause the ejector rod 10 to separate from the product, and the product will be trapped at the upper end of the blanking plate 7. Then the user starts the servo motor 6 to drive the blanking plate 7 to flip upward, causing the blanking plate 7 to tilt, thereby lifting multiple products through the tilt of the blanking plate 7, allowing the products to slide along the blanking plate 7 into the collection box 9 for collection.
