Description

Technical Field

[0001] This utility model relates to the field of automated injection molding and de-insertion technology, specifically to an automated injection molding and de-insertion device based on inserts. Background Technology

[0002] When inserts are injection molded, they can be nested and then injection molded by an injection molding machine. During the nesting process, the inserts are placed stably in the injection molding machine by hand, and the injection molding is automated. After demolding with the demolding device, the inserts and injection molded parts are then manually separated for use. However, during use, prolonged manual operation can easily lead to inaccurate insertion position and affect the yield of injection molded parts.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application CN202211272024.3, filed on 2022-10-18) provides a robotic arm for demolding the injection molding of automotive rearview mirror housings. This arm utilizes a combination of upper, lower, and folding edge modules with the injection mold cavity to form a complete injection space for the automotive rearview mirror housing. A telescopic component linearly drives the embedded module to enter and exit the mold cavity from the demolding port, facilitating demolding of the main body. The upward movement of the inner folding edge mold and the flipping of the inner corner mold achieve comprehensive demolding. Only one telescopic component is needed for linear control to achieve demolding actions in multiple directions, simplifying the equipment's operation and reducing demolding difficulty. This robotic arm is compatible with traditional upper and lower injection molds to achieve complete processing of the automotive rearview mirror housing. While existing technology can complete injection molding and embedding, it often results in numerous steps for loading and positioning the injection molded inserts, affecting product production stability and quality. Furthermore, it is not convenient for achieving full automation, impacting production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As Figures 1-3The present invention provides the following technical solution: an automated injection molding and de-embedding device based on inserts, comprising: a transfer tray 3, slidably connected to the upper surface of a servo module 2, and a feeding fixture 4 mounted on the upper surface of the transfer tray 3, and the inner surface of the feeding fixture 4 for loading a comb head 5, while the comb head 5 is used for nesting connection with hardware 6, and a feeding clamping mechanism is provided on the frame 1; the transfer tray 3 and the servo module 2 constitute a limiting movement structure, and the servo module 2 is symmetrically arranged about the central axis of the inner surface of the frame 1, while the comb head 5 and hardware 6 constitute an internal structure; the feeding clamping mechanism includes a mechanical main arm frame 8 mounted on the side of the frame 1, and a pin seat 9 mounted on the outer surface of the mechanical main arm frame 8, and a telescopic pin body in the pin seat 9 for fixing hardware 6, while a clamping cylinder 10 is mounted on the rear side of the outer surface of the mechanical main arm frame 8; The main boom 8 of the machine forms a limiting telescopic structure with the ejector pin seat 9 and the ejector pin body, and the ejector pin body and the hardware 6 form a limiting structure.

The inner surface of the clamping cylinder 10 is telescopically connected to the telescopic rod 11, and the outer surface of the telescopic rod 11 is equipped with a moving part 12. The outer side of the moving part 12 is limited and slidably connected to the second track 13, and the second track 13 is installed on the main boom 8. At the same time, the outer surface of the moving part 12 is equipped with a clamping plate 14, and the inner surface of the clamping plate 14 is nested with a top block 15. The outer surface of the top block 15 is nested with a comb 5. The clamping cylinder 10 forms a telescopic structure with the moving part 12 through the telescopic rod 11, and the moving part 12 forms a limiting sliding structure with the main boom 8 through the second track 13. The moving part 12, the clamping plate 14 and the top block 15 form an integrated structure.

[0026] In use, the hardware 6 is manually inserted into the designated position of the comb head 5. Then, the comb head 5 and hardware 6, combined, are pre-placed inside the loading fixture 4 assembled on the transfer tray 3 for positioning and nesting. The servo module 2 assembled on the frame 1 controls the transfer tray 3 for directional conveying, controlling the comb head 5 and hardware 6 to move to the corresponding loading position.

The top block 15 on the mechanical auxiliary boom 16 clamps the comb head 5 on the injection molding machine and controls the comb head 5 to detach from the injection molded part 7, thereby controlling the sprue 20 on the injection molded part 7 to detach from the mold. Then, the main mechanical boom 8 can be controlled again to carry the comb head 5 and hardware 6 to the injection molding machine. On the machine, the finished product removed by the mechanical auxiliary boom 16 will move the sprue clamp 17 assembled by the mechanical auxiliary boom 16, and cooperate with the side detector 18 of the sprue clamp 17 to detect the position of the sprue material 20, improve the clamping accuracy of the sprue material 20 by the sprue clamp 17, and start the ultrasonic vibrator 19 assembled by the mechanical auxiliary boom 16 to separate the sprue material 20 from the injection molded part 7, thereby controlling the production effect of the injection molded part 7, controlling the mechanical main boom 8 to pick up the material again, and the mechanical auxiliary boom 16 to transport the finished product to the separation base 21.

[0029] Example 3: Figure 1 and Figure 5The technical solution shown, based on Embodiment 2, further discloses the separation work of the separation base 21 between the finished product and the comb head 5. The specific content is as follows: The separation base 21 is installed on the right side of the frame 1, and the outer surface of the separation base 21 is equipped with a separation cylinder 22.

The separation base 21 forms a nested structure with the comb head 5 and the injection molded part 7 through the separation fixture 24 and the positioning fixture.

[0030] When the mechanical auxiliary boom 16 transports the finished product to the separation base 21, it is stably nested on the separation fixture 24 and the positioning fixture. The separation cylinder 22, which controls the assembly of the separation base 21, is activated, and the separation fixture 24, which is installed on the telescopic component 23, is extended to both sides of the separation base 21. The separation fixture 24 and the positioning fixture are controlled to separate the comb head 5 and the injection molded part 7. The separated comb head 5 is then grabbed and transported back to another position. The separated finished product will then be grabbed and removed by other equipment to continue testing in other steps.
