Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to a positive and negative electrode wire embedded injection molding anti-deviation pressure needle structure. Background Art

[0002] Injection molding technology is a method of manufacturing plastic products. It injects molten plastic material into a mold under high pressure, and forms the desired plastic product after cooling and solidification. The advantages of this technology are fast production speed and high efficiency. The operation can be automated, and the shape and size of the product can be flexibly adjusted according to demand. From simple to complex shapes, from small to large sizes, they can be accurately manufactured. In addition, the replacement of injection molded products is relatively easy. The injection molding process is a very important type of technology in the processing of plastic products. It is widely used in many industries. In the process of injection molding the shell of the lithium-ion battery pack, we found that the positive and negative wires in the shell of the lithium-ion battery pack are unsupported and suspended in the middle of the plastic product. The plastic at the front of the injection molding filling and flow will push the positive and negative wires away from their original positions. For this reason, we proposed a positive and negative wire embedded in the injection molding anti-deviation pressure pin structure. Utility Model Content

An injection molding box 4 is fixedly installed on the bottom inner wall of the injection molding platform 1, and an L-shaped injection molding heating tube 5 is fixedly connected to the back of the injection molding box 4. Two groups of symmetrical and vertical support plates 9 are fixedly arranged on the bottom inner wall of the injection molding platform 1 corresponding to the sides of the injection molding box 4. The tops of the two groups of support plates 9 are fixedly connected with molds 14. The top of the pressure needle fixing plate 3 A pressing needle top plate 7 is fixedly installed, and a fixing mechanism is provided on the mold 14. A vertical pressing needle 8 is fixedly connected to the bottom of the pressing needle top plate 7. Six groups of pressing needles 8 are provided, and three groups are provided in each row. When the device starts to work, the two groups of oil cylinders 2 are first started, and the input ends at the bottom of the two groups of oil cylinders 2 push the pressing needle fixing plate 3 downward. The pressing needle top plate 7 drives the six groups of pressing needles 8 at the bottom to descend synchronously through the descent of the pressing needle fixing plate 3. During the descent of the six groups of pressing needles 8, they gradually extend into the injection mold cavity 10 through the six groups of pressing needle holes 11;

[0020] The fixing mechanism includes an injection mold cavity 10, a pressure pin hole 11 and positive and negative electrode wires 12. The injection mold cavity 10 is opened inside the mold 14, and the pressure pin holes 11 are opened on the top of the mold 14 corresponding to the six groups of pressure pins 8. The positive and negative electrode wires 12 are movably installed on the bottom inner wall of the injection mold cavity 10 corresponding to the positive and negative electrode wires 12 directly below each row of pressure pin holes 11.

[0021] The pressure needle hole 11 penetrates into the injection mold cavity 10, and three groups of mold grooves 13 are opened between the bottom inner wall of the injection mold cavity 10 corresponding to the two groups of positive and negative electrode wires 12. When the bottom of the six groups of pressure needles 8 drops to press the top of the two groups of positive and negative electrode wires 12, the position of the positive and negative electrode wires 12 can be fixed. At this time, the injection molding box 4 is started again, and the injection molding box 4 transports the heated raw materials to the feed pipe 6 through the injection heating tube 5. The raw materials enter the injection mold cavity 10 through the feed pipe 6. The raw materials are gradually accumulated in the injection mold cavity 10 through the input of the injection heating tube 5, and the raw materials flow into the three groups of mold grooves 13 through extrusion.

[0022] A vertical feeding tube 6 is fixedly provided at the top of the mold 14 corresponding to the sides of two groups of pressing pin holes 11. As the pressing pin 8 is lifted, the bottom end of the pressing pin 8 gradually detaches from the injection mold cavity 10 through the six groups of pressing pin holes 11. When the pressing pin 8 is completely detached from the pressing pin hole 11, the six groups of pressing pin holes 11 are filled by injection molding to complete the injection molding. This device solves the short-circuit problem of the positive and negative electrode wires 12, and also solves the output of products with poor appearance, improves the quality of the products, eliminates the step of manually inspecting the appearance characteristics of the products, and saves manpower and labor costs.

[0023] The end of the injection molding heating tube 5 extends into the feed tube 6, and the bottom of the feed tube 6 extends to the injection mold cavity 10. The raw material enters the injection mold cavity 10 through the feed tube 6. The raw material is gradually accumulated in the injection mold cavity 10 through the input of the injection molding heating tube 5. The raw material flows into the three groups of mold grooves 13 through extrusion. When the injection mold cavity 10 is full, the two groups of oil cylinders 2 are started again, so that the two groups of oil cylinders 2 drive the input end at the bottom to drive the pressure needle fixing plate 3 to lift upward. When the pressure needle fixing plate 3 is lifted, the six groups of pressure needles 8 connected to the pressure needle top plate 7 are lifted.

[0024] Working principle: When the device starts to work, first start the two groups of oil cylinders 2, the input ends at the bottom of the two groups of oil cylinders 2 push the pressure needle fixing plate 3 downward, and the pressure needle top plate 7 drives the six groups of pressure needles 8 at the bottom to descend synchronously through the descent of the pressure needle fixing plate 3. During the descent of the six groups of pressure needles 8, they gradually extend into the injection mold cavity 10 through the six groups of pressure needle holes 11. When the bottom of the six groups of pressure needles 8 drops to press the top of the two groups of positive and negative wires 12, the position of the positive and negative wires 12 can be fixed. At this time, start the injection molding box 4 again. The injection molding box 4 transports the heated raw materials to the feed pipe 6 through the injection heating pipe 5. The raw materials enter the injection molding cavity through the feed pipe 6. In the mold cavity 10, the raw materials are gradually accumulated in the injection mold cavity 10 through the input of the injection molding heating tube 5, and the raw materials flow into the three groups of mold grooves 13 through extrusion. When the injection mold cavity 10 is full, the two groups of oil cylinders 2 are started again, so that the two groups of oil cylinders 2 drive the input end at the bottom to drive the pressure needle fixing plate 3 to lift upward. When the pressure needle fixing plate 3 is lifted, the six groups of pressure needles 8 connected to the pressure needle top plate 7 are lifted. The bottom end of the pressure needle 8 gradually detaches from the injection mold cavity 10 through the six groups of pressure needle holes 11 as the pressure needle 8 is lifted. When the pressure needle 8 is completely separated from the pressure needle hole 11, the six groups of pressure needle holes 11 are filled with injection molding to complete the injection molding. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
