Description

Technical Field

[0001] The utility model relates to an insert embedding device, in particular to a flexible insert embedding device for heating. Background Art

[0002] Plastic parts such as automobile dashboards and door trims are embedded with flexible hemp boards during injection molding to reduce weight and reduce the use of plastic particles. This process is widely used in the field of injection molding engineering. In the existing hemp board injection molding process, in order to ensure the bonding degree between the hemp board insert and the plastic, the hemp board is generally heated to the required temperature before embedded injection molding.

[0003] The existing method of heating hemp board inserts is basically to use semi-automatic ovens and other equipment to heat the inserts through heat conduction, and the hemp boards are placed in and taken out manually or semi-automatically. The operation process is cumbersome, inefficient, and there is a risk of high-temperature burns. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a flexible insert embedding device for heating with high heating efficiency and safe use, which can be automatically placed in a heating oven for heating and automatically taken out.

[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a flexible insert embedding device for heating, comprising a clamping heat-resistant frame, a plurality of clamping pins elastically arranged downward at the bottom of the clamping heat-resistant frame through an elastic telescopic mechanism, and a first quick-release connector fixedly arranged on one side of the clamping heat-resistant frame, the positions of the plurality of clamping pins corresponding to the positions of the positioning holes opened on the hemp board to be processed, the upper end of the clamping pin is an elastic spindle structure with an outer diameter gradually decreasing from the middle to both ends, when the hemp board to be processed is clamped, the upper end of the clamping pin is elastically embedded in the positioning hole, and when the hemp board to be processed is embedded in the designated processing position in the mold cavity of the injection molding machine, the clamping pin is elastically moved out of the positioning hole.

[0006] Compared with the prior art, the utility model has the advantage that the hemp board can be accurately positioned and automatically placed in a heating oven for automatic heating. After the heating is completed, the heat-resistant frame can be automatically taken out by a second quick-release connector arranged on the manipulator and quickly connected to the first quick-release connector. This part is an existing conventional automatic quick-release structure and is accurately and efficiently embedded in the injection molding machine, which greatly shortens the automation cycle and improves the injection molding production efficiency. The clamping pin head is an elastic spindle structure with an outer diameter gradually decreasing from the middle to both ends, which can conveniently clamp the hemp board to be processed or disengage from the positioning hole of the hemp board to be processed, thereby realizing rapid clamping of the hemp board to be processed or detaching from the hemp board to be processed without damaging the structure of the hemp board to be processed.

[0007] The elastic telescopic mechanism comprises a fixing frame, an L-shaped positioning plate, a limiting snap ring, a sliding guide sleeve and a compression spring, one end of the fixing frame is fixedly connected to the clamping heat-resistant frame, the L-shaped positioning plate is fixedly arranged downwardly at the bottom of the fixing frame, the direction in which the other end of the fixing frame faces and the bottom of the L-shaped positioning plate are parallel to the clamping heat-resistant frame, the other end of the fixing frame is provided with a U-shaped slot, the bottom of the L-shaped positioning plate is provided with a guide hole aligned with the inside of the U-shaped slot, the sliding guide sleeve is fixedly connected to the bottom of the L-shaped positioning plate and extends into the guide hole, the lower end of the clamping pin head passes downward through the sliding hole inside the sliding guide sleeve, the upper part of the clamping pin head passes upward through the U-shaped slot, the limiting snap ring is fixedly arranged on the clamping pin head, the compression spring is sleeved on the clamping pin head and elastically compressed between the limiting snap ring and the bottom of the L-shaped positioning plate, and the compression spring elastically connects the limiting snap ring to the bottom of the fixing frame. When the clamping pin head extends into the positioning hole of the hemp board to be processed, the limiting clamp ring squeezes the compression spring downward, so that the contact between the upper end of the clamping pin head and the hemp board to be processed is softer, effectively protecting the structure of the hemp board and not easily causing damage. When the clamping pin head has extended into the positioning hole, the compression spring resets and elastically connects the limiting clamp ring to the bottom of the fixed frame to ensure that the clamping pin head firmly clamps the hemp board to be processed; the sliding guide sleeve adopts a brass graphite guide sleeve, which has good high temperature resistance and wear resistance.

[0008] A triangular reinforcing rib is fixedly arranged between the fixing frame and the L-shaped positioning plate, so as to enhance the connection strength between the structures and extend the service life of the automation equipment.

[0009] The clamping heat-resistant frame includes a heat-resistant fixed frame and a heat-resistant anti-sticking net fixedly arranged inside the heat-resistant fixed frame. The elastic telescopic mechanism is fixedly connected to the heat-resistant fixed frame and is located at the bottom of the heat-resistant anti-sticking net. The upper end of the clamping pin head passes through the net opening of the heat-resistant anti-sticking net upward. The space on both sides of the heat-resistant anti-sticking net is fully utilized to set various structures, reduce the space required on one side, and effectively ensure the balance performance during clamping; the heat-resistant anti-sticking net is made of Teflon material, which is resistant to high temperature and prevents the hemp board from sticking and being unable to be detached after heating.

[0010] A heat-insulating plate is fixedly arranged on the inner side of the first quick-release connector on the clamping heat-resistant frame, so as to reduce the heat conduction of the first quick-release connector to the high temperature during heating, and effectively protect the structure of the first quick-release connector from being damaged by high temperature.

[0011] At least one positioning concave block is fixedly arranged at the bottom of the clamping heat-resistant rack, and a positioning groove is arranged at the bottom of the positioning concave block. By arranging a positioning convex block that cooperates with the positioning groove for positioning in the heating oven, it can be better ensured that the position of the clamping heat-resistant rack after being placed in the oven remains basically unchanged, and the consistency of the hemp board after heating is ensured, thereby improving the quality of the overall product.
