Description

Technical Field

[0001] This utility model relates to the field of electronic water pump manufacturing technology, and in particular to an automatic insert injection molding mechanism for an electronic water pump body. Background Technology

[0002] In the production of electronic water pump bodies, to meet the structural strength requirements of the pump body and subsequent assembly needs, metal inserts (such as connecting screws, locating pins, etc.) need to be cured into a single unit with the plastic substrate through injection molding. With the promotion of automated production technology, the industry generally uses automatic insert injection molding mechanisms to complete this process. Its typical structure is as follows: a robotic arm and an insert conveying mechanism are configured next to the injection molding machine. The insert conveying mechanism transports the insert to the designated gripping station according to a preset posture. After receiving the control signal, the robotic arm automatically grips the insert and accurately transfers it into the insert mounting slot of the injection molding machine mold. After the insert is positioned, the injection molding machine closes the mold and injects molten plastic, finally completing the integrated injection molding of the insert and the pump body.

[0003] However, existing automatic insert injection molding mechanisms suffer from the following key technical defects in practical applications, which seriously affect production efficiency and product accuracy: The robotic arm suffers from poor ease of installation and position adjustment: The robotic arm needs precise alignment with the material outlet of the insert conveying mechanism and the insert slot of the injection molding machine mold, requiring multi-dimensional position adjustments in front-back, left-right, and height. Existing robotic arms rely on independent mounting bases for fixation, and the adjustment process requires auxiliary components such as adjusting screws and sliding guides. Furthermore, it necessitates repeated disassembly of positioning components and calibration of coordinate parameters, making the operation cumbersome. This not only hinders rapid and accurate positioning but also significantly extends the installation and debugging cycle, increasing labor costs. The robotic arm and injection molding machine suffer from weak overall integration and insufficient connection stability: The independent mounting base needs to be fixed to the injection molding machine body via connectors, but existing connectors are mostly general standard parts or simple welded structures, which cannot form a tight fit, resulting in uneven gaps between the mounting base and the injection molding machine. Under the high-frequency mold closing vibration of the injection molding machine, the connection is prone to loosening, which in turn causes relative positional movement between the robotic arm and the injection molding machine, resulting in insert positioning deviations and affecting the injection quality of the pump body. Poor connector compatibility: When producing pump bodies of different specifications of electronic water pumps, it is necessary to adjust the position of the robotic arm mounting base to adapt to the insert slot of the new mold. Due to the fixed structure, the existing connectors cannot flexibly match the new mounting hole positions after the adjustment of the mounting base. It is necessary to process and customize connectors separately for specific positions or re-purchase compatible models. This not only increases the cost of equipment modification and spare parts inventory pressure, but also prolongs the production changeover cycle and reduces the adaptability of the mechanism to different specifications of products.

[0024] As a preferred embodiment of the above embodiments, each of the limiting nuts 19 is coaxially mounted with an auxiliary rotating ring 24; In this embodiment, The auxiliary rotating ring 24 is coaxially mounted on the limit nut 19, which increases the operating force-bearing area of ​​the limit nut 19. This makes it easier for the operator to rotate the limit nut 19 to adjust the position of the lifting plate 6 during the coarse adjustment stage, reducing the difficulty of adjustment and improving the adjustment efficiency of the limit assembly.

This improves the accuracy of insert gripping and placement and ensures the injection molding quality of pump body.

[0026] The working principle of this utility model is as follows: First, install the robotic arm 2 on the fixed plate 21 on top of the lifting plate 6. Then, adjust the left and right positions of the robotic arm 2: loosen the nut of the locking threaded rod 12 in the left and right adjustment mechanism, push the slider 10 to slide left and right along the sliding shaft 9, and after the robotic arm 2 is aligned with the injection molding mold insert groove and the discharge end of the conveying mechanism 3 in the left and right directions, tighten the nut to fix the slider 10. Next, adjust the front and back positions: loosen the nut of the adjusting threaded rod 15 in the front and back adjustment mechanism, push the adjusting block 14 to slide back and forth along the channel steel 13, and after the robotic arm 2 is accurately aligned in the front and back directions, tighten the nut to fix the adjusting block 14. Finally, adjust the height: operate the lifting component 7 (manual jack) to lift or lower the lifting plate 6. 6. Slide along the guide shaft 5 and the limiting threaded rod 18. After the height of the robotic arm 2 is adapted, adjust the limiting nut 19 to make it fit tightly against the upper and lower surfaces of the lifting plate 6 and lock the position of the lifting plate 6. During the adjustment process, the stabilizing ring 22 and the stabilizing frame 23 ensure the stability of the guide shaft 5 and the limiting threaded rod 18.
