A water inlet 20 is provided on the bottom side of the hook needle 19, and the water inlet 20 is connected to the front mold core 13; the lower mold plate 4, the bottom side of the lower mold plate 4 is connected to the lower fixed plate 2, and the middle end of the lower mold plate 4 is slidably connected to the rear mold core 12 that is molded with the front mold core 13, and the mold feet 5 respectively fixedly connected to the front and rear ends of the top side of the lower fixed plate 2 are used to support the ejection. The structure of the side is formed, and a cavity is formed. Two ejector panels 6 are arranged in the cavity on the side close to the mold feet 5 at both ends. The top side of the ejector panel 6 is provided with a spring 8, and the bottom side of the ejector panel 6 is provided with an ejector bottom plate 7. The bottom side of the ejector bottom plate 7 is connected to the lower fixed plate 2 through a garbage nail 9.

Reset block 18 is fixedly connected to the bottom side of the front mold core 13. When the front mold core 13 and the rear mold core 12 are molded together, the reset block 18 will follow the displacement of the front mold core 13 and abut against sliding block 16, thereby causing sliding block 16 to move toward the middle end and close, and stabilize the dual-electric three-phase copper busbar support after injection molding. When the mold is opened, the reset block 18 is separated from sliding block 16, so that sliding block 16 is separated from the dual-electric three-phase copper busbar support. Nylon plugs 25 are fixedly connected to the left and right ends of the top side of the lower mold plate 4.

[0037] Specifically, the positioning groove can be used to position the copper bar 27 and stainless steel bushing 28 that have not been injection molded and are placed in the positioning groove before injection molding, thereby avoiding the poor finished product caused by the offset of the copper bar 27 and stainless steel bushing 28 during the injection molding process, thereby improving the qualified rate of the finished product. When opening the mold, after the stripping plate 10 and the upper mold plate 3 are lifted up in cooperation with the automated equipment, the ejector panel 1 6 and the ejector panel 2 23 are driven to lift the ejector 24 to lift and demold the double-electric three-phase copper bar support after injection molding, so that the double-electric three-phase copper bar support adhered to the rear mold core 12 can be quickly separated from the rear mold core 12, and the subsequent unloading work can be quickly unloaded to improve production efficiency.

[0038] The front mold core 13 and the adjacent side of the rear mold core 12 are spliced ​​to form a cavity. The bottom end of the sprue 11 passes through the bottom side of the stripper plate 10 and is connected to the cavity, so that the sprue 11 is used to inject raw materials into the cavity along the sprue 20 for injection molding. A mold water transport interface 26 is provided inside the lower mold plate 4. The front and rear openings form a cycle of inlet and outlet to transport water to heat or cool the mold, which is determined according to the characteristics of the plastic raw materials. Commonly used methods include oil transport, water transport, steam transport, etc.

[0039] A wear-resistant block 17 is provided at the middle end of the top side of the lower template 4, and the bottom side of the rear mold core 12 is located on the top side of the wear-resistant block 17. The rear mold core 12 and the lower template 4 adopt a drawer-type design, which can pull out the rear mold core 12 at the opening on the lower template 4, and then cooperate with automated equipment to quickly load and unload materials to improve production efficiency. The wear-resistant block 17 helps to reduce the wear between the lower template 4 and the rear mold core 12 and extend the service life.

[0040] Working principle: Before the injection molding of the dual-electric three-phase copper busbar support, first load the material, insert 6 copper busbars 27 and 4 stainless steel bushings 28 into the alignment positioning grooves in the pulled-out rear mold core 12, and position them in the positioning grooves. The specifications of the positioning grooves correspond to the specifications of the copper busbars 27 and the stainless steel bushings 28. If an offset occurs, it is observed that the mold is not in good condition, so as to adjust the position of the parts to reduce the damage rate of the copper busbars 27 and the stainless steel bushings 28 and improve the accuracy of subsequent mold closing. Then the rear mold core 12 is slid into the lower mold plate 4 along the guide rail 14, and then the mold is closed. The reset block 18 will follow the displacement of the front mold core 13 and abut against the slider 16, so that the slider 16 is displaced to the middle end and closed, and then injection molding is started. The raw material is injected into the injection port, and the raw material is injected into the cavity through the material head 11 along the water inlet 20 for injection molding. The injection molded part 29 is formed in the cavity formed by the mold core 12, and is combined with the copper busbar 27 and the stainless steel bushing 28 to form a double-electric three-phase copper busbar support. The mold water transport interface 26 arranged inside the lower template 4 has two front and rear openings, one in and one out, to form a cycle for water transport. The mold is heated or cooled according to the characteristics of the plastic raw material to assist in the processing and molding of the product. After the product is formed, the mold is opened, the stripping plate 10 and the upper template 3 are lifted in turn, the reset block 18 is separated from the slider 16, and the slider 16 is separated from the double-electric three-phase copper busbar support. After the stripping plate 10 and the upper template 3 are lifted in cooperation with the automated equipment, the ejector panel 1 6 and the ejector panel 2 23 are driven to lift the ejector 24 to lift and demold the double-electric three-phase copper busbar support, so that the double-electric three-phase copper busbar support adhered to the rear mold core 12 is quickly separated from the rear mold core 12, and the rear mold core 12 is pulled out for unloading.

[0041] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
