Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to an injection molded part removal device. Background Technology

[0002] In injection molding production, it is necessary to simultaneously mold or assemble multiple injection molded parts with relatively small structural dimensions, such as connector housings and other specific functional sub-assemblies. These sub-assemblies are embedded in different positions in the mold, and after molding, they need to be removed from the mold one by one and sorted according to the process requirements.

[0003] Currently, the main method for removing parts from molds on production lines is manual operation. Operators use hand tools to remove sets of injection molded parts distributed within the mold and manually place them into corresponding sorting containers. While this method offers high flexibility, it generally suffers from the following problems: First, the removal efficiency is low, especially when the number of injection molded parts in the mold is large or their distribution is dense. Operators need to constantly change their removal position and posture, resulting in high labor intensity. Second, this method requires a large number of manual laborers, which is detrimental to improving the level of production automation and the stable control of production cycle time. Therefore, to solve these problems, an injection molded part removal device is needed. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by proposing a part removal device for injection molded parts. The specific technical solution is as follows:

[0005] A part removal device for injection molded parts, characterized in that:

[0006] Includes frame, conveyor, mold positioning table, support frame, three-axis moving mechanism and gripping mechanism;

[0007] The conveying device and the mold positioning table are arranged adjacent to each other on the top of the frame, and the support frame is located between the conveying device and the mold positioning table;

[0008] The three-axis moving mechanism is mounted on the support frame, and the gripping mechanism is mounted on the final moving part of the three-axis moving mechanism;

[0009] The mold positioning platform is used to place the mold, and the gripping mechanism can take out the injection molded part from the preset position in the mold and then grip it onto the conveying device;

[0010] The gripping mechanism includes a support, a rotary cylinder, a rotating plate, a lifting cylinder, and an adsorption assembly;

[0011] The rotary cylinder is mounted on the bracket, and the rotating plate is fixedly connected to the output end of the rotary cylinder;

[0012] The lifting cylinder is mounted on the rotating plate, and the adsorption assembly is mounted on the telescopic end of the lifting cylinder.

[0013] To better realize this utility model, it can be further made as follows:

[0014] The three-axis moving mechanism includes an X-axis sliding component, a Y-axis sliding component, and a Z-axis sliding component;

[0015] The X-axis sliding assembly is mounted on the support frame, and the sliding direction is along the width direction of the frame;

[0016] The Y-axis sliding assembly is mounted on the sliding part of the X-axis sliding assembly, and the sliding direction is along the length of the frame;

[0017] The Z-axis sliding assembly is mounted on the sliding part of the Y-axis sliding assembly, and the sliding direction is along the height direction of the frame, which is used to drive the adsorption assembly to move up and down along the height direction.

[0018] Furthermore: the adsorption assembly includes a lifting plate and an adsorption head;

[0019] The lifting plate is fixedly connected to the lifting end of the lifting cylinder, and the suction head is installed on the lifting plate. The suction head, in conjunction with the three-axis moving mechanism, is used to pick up and place injection molded parts at multiple preset points.

[0020] Furthermore: the conveying device is arranged along the length of the frame, and the conveying device includes a conveying support, a conveyor belt and a drive motor. The conveyor belt is installed on the conveying support, and the drive motor is used to drive the conveyor belt to run.

[0021] Furthermore, the rack has an internal electrical distribution chamber for installing an electrical control box.

[0022] Furthermore, the bracket is detachably connected to the sliding part of the Z-axis sliding assembly.

[0023] The beneficial effects of this utility model are as follows:

[0024] First, the three-axis moving mechanism, in conjunction with the rotary cylinder and the lifting cylinder, enables the gripping mechanism to be adjusted in space, thereby achieving the gripping and accurate placement of injection molded parts in different positions and postures within the mold. This significantly improves the efficiency of automated part removal, reduces the intensity of manual labor, and facilitates integration with subsequent visual recognition and classification systems.

[0025] Secondly, the gripping mechanism adopts an adsorption component structure, which completes the part removal by non-destructive contact between the adsorption head and the surface of the injection molded part. This overcomes the problem that traditional mechanical grippers can easily cause scratches or deformation to the product, effectively ensuring the surface quality of the product and improving the yield of injection molded parts.

[0026] Third, the bracket and the Z-axis sliding component adopt a detachable connection structure, which facilitates the quick replacement and maintenance of the gripping module. It can flexibly select and match the appropriate adsorption components according to the structural characteristics of the injection molded parts in different molds, thereby improving the modular expansion capability of the system.

[0033] like Figures 1 to 3 As shown:

[0034] A part-retrieving device for injection molded parts includes a frame 1, a conveying device, a mold positioning table 2, a support frame 19, a three-axis moving mechanism 6, and a gripping mechanism 7.

[0035] The conveying device and the mold positioning table 2 are arranged adjacent to each other on the top of the frame 1. The support frame 19 is located between the conveying device and the mold positioning table 2 and is used to install the three-axis moving mechanism 6.

[0036] The conveying device includes a conveying support 3, a conveyor belt 4 and a drive motor 5. The conveying support 3 is arranged along the length of the frame 1, and the conveyor belt 4 is installed on the conveying support 3.

[0037] The drive motor 5 is fixed to one end of the conveyor bracket 3 and is driven by an AC servo motor or a stepper motor. It drives the conveyor belt 4 through the roller shaft. The conveyor belt 4 is made of anti-static material to suit the environment in which plastic products are handled.

[0038] The frame 1 has an internal power distribution chamber 17 for installing the electrical control box. The power distribution chamber 17 is structurally partitioned by a support plate 18. The electrical control box includes a PLC controller, a power module, a gas supply distribution module, and various electrical wiring terminals.

[0039] The three-axis moving mechanism 6 is mounted on the support frame 19, and the gripping mechanism 7 is mounted on the final moving part of the three-axis moving mechanism 6 to realize the moving and positioning function of the gripping mechanism 7 in three-dimensional space. The mold positioning table 2 is used to place the injection mold. After the gripping mechanism 7 removes the injection molded part from the preset position in the mold, it transfers the injection molded part to the conveying device and then to the vision classification system.

[0040] Specifically, the three-axis moving mechanism 6 includes an X-axis sliding component 8, a Y-axis sliding component 9, and a Z-axis sliding component 10.

[0041] The X-axis sliding assembly 8 is mounted on the support frame 19, and its sliding direction is along the width direction of the frame 1. The Y-axis sliding assembly 9 is mounted on the sliding part of the X-axis sliding assembly 8, and its sliding direction is along the length direction of the frame 1. The Z-axis sliding assembly 10 is mounted on the sliding part of the Y-axis sliding assembly 9, and its sliding direction is along the height direction of the frame 1. The sliding part of the Z-axis sliding assembly 10 serves as the mounting part of the gripping mechanism 7.

[0042] Specifically, the X-axis sliding component 8, the Y-axis sliding component 9, and the Z-axis sliding component 10 can all be implemented using existing linear guide rails or ball screw modules.

[0043] The gripping mechanism 7 includes a bracket 11, a rotary cylinder 12, a rotating plate 13, a lifting cylinder 14, and an adsorption assembly. The bracket 11 is detachably connected to the sliding part of the Z-axis sliding assembly 10. Specifically, the bracket 11 is locked to the sliding part of the Z-axis sliding assembly 10 by bolts, which facilitates quick replacement of the gripping mechanism 7.

[0044] A rotary cylinder 12 is fixedly mounted on a bracket 11, and its output end is connected to a rotary plate 13. A lifting cylinder 14 is mounted on the rotary plate 13, and a lifting plate 15 is fixedly connected to the lifting end of the lifting cylinder 14. An adsorption assembly is fixedly mounted on the lifting plate 15.

[0045] The adsorption assembly includes a lifting plate 15 and at least one adsorption head 16, which is connected to an external vacuum generator via a vacuum pipeline. The lifting plate 15 is fixed to the output shaft end face of the lifting cylinder 14 by screws, and the adsorption head 16 is fixed to the lifting plate 15.

[0046] The working process of this utility model is as follows: After the injection-molded mold is placed on the mold positioning table 2, the three-axis moving mechanism 6 drives the gripping mechanism 7 to move to the preset part-removing position. The rotary cylinder 12 is used to adjust the posture and direction of the gripping mechanism 7 to adapt to the removal angle of the injection-molded part in the mold. Subsequently, the lifting cylinder 14 drives the adsorption assembly to move downward, so that the adsorption head 16 contacts the injection-molded part and completes adsorption. After adsorption is completed, the lifting cylinder 14 raises the adsorption assembly, and the three-axis moving mechanism 6 moves the gripped injection-molded part above the conveying device. The lifting cylinder 14 is driven to descend again to accurately place the injection-molded part on the conveyor belt 4. Finally, the conveyor belt 4 transports the injection-molded part to the vision recognition system to complete the subsequent recognition and classification processing. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
