Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a loading and unloading clamp for injection molding parts. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting.

[0003] During injection molding, the raw material needs to be placed in the injection mold. After molding, the molded part is removed. Since the raw material changes after being formed by the injection mold, the clamps used for loading are no longer applicable, and additional unloading clamps are required, which increases the cost. Due to the high temperature of the injection mold, manual loading and unloading pose certain safety hazards and are inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a material handling gripper for injection molding.

[0010] Furthermore, the fixing plate is provided with a reinforcing plate to enhance the connection strength between the fixing plate and the connecting plate, which can also enhance the connection strength between the support plate and the fixing plate.

[0011] Furthermore, the reinforcing plate is provided in several groups, and the reinforcing plate is arranged in a trapezoidal shape.

[0012] The beneficial technical effects of this utility model are as follows: the base can be mounted on a six-axis robotic arm, which can move the suction component to the preheated injection molding material, then grasp it, and then move it to the injection mold, thereby realizing the feeding process of the injection molding material. After the injection is completed, the gripping component can be used to grasp the molded injection part in the injection mold and then place it at the cutting mechanism, thus realizing automatic loading and unloading without manual operation, avoiding safety hazards caused by high temperature, and having high work efficiency, eliminating the need to replace the robotic arm, and reducing costs.

[0019] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] See appendix Figure 1-4As shown, an injection molding part loading and unloading gripper in Embodiment 1 includes a base for fixing to an external six-axis robot; a suction component mounted on the base for gripping preheated injection molding material, which can place the gripped injection molding material into the injection mold; and a gripping component mounted on the base for gripping the molded injection part.

[0021] The base can be mounted on a six-axis robotic arm. The six-axis robotic arm can move the suction component to the preheated injection molding material, then grasp it and move it to the injection mold, thus realizing the material loading process. After injection molding is completed, the gripping component can grasp the molded injection part in the injection mold and place it at the cutting mechanism. This achieves automatic loading and unloading without manual operation, avoiding safety hazards caused by high temperature, and has high work efficiency. It also eliminates the need to replace the robotic arm, reducing costs.

[0022] The base includes: a fixed plate 1; a connecting plate 11 that can be fixed to an external six-axis robot; a connecting bracket 12 fixed to the fixed plate 1 and used for mounting the suction component; and a support plate 13 fixed to the fixed plate 1 and used for mounting the gripping component.

[0023] The connecting plate 11 is used for fixed connection with the six-axis robot, the suction component can be installed on the connecting bracket 12, and the gripping component can be installed on the support plate 13.

[0024] Furthermore, the gripping assembly includes: a first cylinder 2 fixed on the support plate 13; a transmission plate 21 disposed at the output end of the first cylinder 2; a drive module 22 disposed on the transmission plate 21; and a clamp 23 capable of close-range gripping via the drive module 22.

[0025] When the drive module 22 is working, it can clamp and fix the injection molded part after molding through the clamp 23. The first cylinder 2 can make the clamp 23 move forward or backward, so as to facilitate the insertion into the injection mold to hold the injection molded part.

[0026] Furthermore, the drive module 22 is also provided with a positioning element 24 for positioning the injection molded part.

[0027] Before clamping, the positioning component 24 can be used to position the gripped injection molded part, thereby increasing the stability and accuracy of the clamp 23.

[0028] Furthermore, the suction assembly includes: a second cylinder 3 fixed to the connecting bracket 12; a suction head 31 provided on the output end of the second cylinder 3; a return spring 32 fixed at one end to the suction head 31, the other end of which is provided with a positioning plate 33; and a positioning groove 34 through which the positioning plate 33 is opened.

[0029] When the injection molding material is preheated, it will be located in the groove opened in the heating platform. Therefore, the positioning plate 33 can be attached to the heating platform, and then the injection molding material is sucked by the suction head 31. When the positioning plate 33 is attached to the heating platform, it will be buffered by the return spring 32. This also allows the injection molding material to be exposed when it enters the injection mold, making it easier to insert into the molding groove of the injection mold.

[0030] Furthermore, the suction head 31 is provided with a vacuum suction column 35 extending into the positioning groove 34, and the suction head 31 is provided with an air pump 36 communicating with the vacuum suction column 35.

[0031] The air pump 36 can suck the injection molding material into the positioning groove 34 through the vacuum suction column 35, thereby realizing the gripping of the injection molding material.

[0032] Furthermore, the fixing plate 1 is provided with a reinforcing plate to enhance the connection strength between the fixing plate 1 and the connecting plate 11. This reinforcing plate can also enhance the connection strength between the supporting plate 13 and the fixing plate 1.

[0033] The strength of the connection can be increased by using reinforcing plates.

[0034] Furthermore, the reinforcing plates are provided in several groups, and the reinforcing plates are arranged in a trapezoidal shape. The trapezoidal arrangement of the reinforcing plates will not affect the installation of the suction component and the gripping component.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
