DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 , 2 , 3, 4, 5, 6, and 7, the present invention provides a technical solution: an injection mold for new energy automobile accessories, comprising: a supporting mechanism comprising a base 1 and a No. 1 side plate 2 and a No. 2 side edge 24 fixedly connected to the top of the base 1, a sliding guide rod 3 fixedly connected between the No. 1 side plate 2 and the No. 2 side edge 24; a die 21 is placed on one side of the No. 2 side edge 24, the die 21 is slidably connected to the sliding guide rod 3, a cutter 26 is slidably connected to the middle of the die 21 for cutting off or holding the excess part of the workpiece, a No. 2 hydraulic cylinder 22 is fixedly connected to the end of the cutter 26, the output end of the No. 2 hydraulic cylinder 22 is fixedly connected to the die 21, and a reset push rod 12 is fixedly connected to the bottom of the die 21; a punch seat 4 is fixedly connected to the outer side of the sliding guide rod 3, and the end of the punch seat 4 A punch 8 is fixedly connected, and a demoulding component is provided between the punch 8 and the punch seat 4; a material receiving component is placed at the bottom of the punch seat 4, and the material receiving component includes a material receiving trough 9 slidably arranged at the bottom of the punch seat 4, and the top and one end of the material receiving trough 9 are opened, and a piston plate 19 is slidably arranged inside the material receiving trough 9, and a compression spring 20 is fixedly connected between the piston plate 19 and the inner wall of the material receiving trough 9, and a high-pressure air duct driving the piston plate 19 to slide is installed at one end of the material receiving trough 9, when the die 21 and the punch 8 are separated, the material receiving trough 9 is placed on one side of the punch 8 to collect the excess parts that are cut off, and when the die 21 and the punch 8 are closed, the reset push rod 12 drives the material receiving trough 9 and the punch seat 4 to form a channel with an open end, and the high-pressure air of the high-pressure air duct drives the piston plate 19 to push the material inside the material receiving trough out.

[0029] It should be noted that the present invention fixes the high-pressure branch pipe to the air duct joint at the end of the material receiving trough 9, drives the die 21 to slide along the guide rail 25 to one side of the punch seat 4 to cooperate with the punch 8, and the injection molding machine injects glue from the injection port on one side of the die 21. After the injection is completed, the punch seat 4 and the die 21 are cooled by the cooling unit. After cold cutting and forming, the second hydraulic cylinder 22 contracts and drives the cutter 26 to move inward to cut the excess part of the workpiece. After the cutting is completed, the die 21 moves along the side of the second side 24 of the guide rail 25. At this time, when the material receiving trough 9 moves to one side of the punch seat 4 under the action of the reset spring 11, the die is demoulded. Under the action of the assembly, there is a gap between the workpiece and the punch seat 4. At this time, the cut part falls into the material receiving trough 9. After the workpiece is removed, when the die 21 and the punch 8 are closed, the reset push rod 12 pushes the material receiving trough 9 to the bottom of the punch seat 4, so that the top plate of the material receiving trough 9 fits with the bottom of the punch seat 4, thereby sealing the top of the material receiving trough 9, so that the material receiving trough 9 forms a rectangular cylinder with one end open. The switch controls the high-pressure air to blow between the material receiving trough 9 and the piston plate 19. Under the action of pressure, the piston plate 19 pushes the material to one end to realize material collection. When the high-pressure air is stopped, the compression spring 20 pulls the piston plate 19 to reset.

[0030] See also Figure 4 , 5 As shown, it also includes a cooling part, including a plurality of cold water pipes 16 placed inside the die 21 and the punch 8, and a bend is provided at the end of two adjacent cold water pipes 16. A spiral blade 17 is installed inside the hollow tube 18 to slow down the water flow rate. The hollow tube 18 is fixedly connected to the inside of the spiral blade 17, and one end of the hollow tube 18 is fixedly connected to a cold air box 13. Semiconductor refrigeration sheets 14 are fixedly connected to both sides of the cold air box 13. The cooling end of the semiconductor refrigeration sheet 14 is attached to the outside of the cold air box 13 and fixedly connected to a plurality of fins 15. The fins 15 are placed inside the cold air box 13 and are staggered.

[0031] It should be noted that one end of the cold water pipe 16 of the present invention is fixedly connected to a vertically upward water inlet joint, the end of the hollow tube 18 is fixedly connected to the cold air box 13, and the hollow tube 18 extends to the inside of the cold air box 13. The cooled water passes through the water inlet joint and travels in a spiral structure in the space between the spiral blades 17 and the inner wall of the cold water pipe 16. During this period, the air enters the cold air box 13. Under the separation effect of the fins 15, the air travels along an S-shaped route inside the cold air box 13. During this period, the semiconductor refrigeration plate 14 transfers the low temperature to the fins 15, so that the fins 15 are always in a low temperature state. The contact between the air and the fins 15 makes the temperature of the air lower. Then the wind enters the hollow tube 18 and travels along the cold water pipe 16 to cool the water inside the cold water pipe 16, thereby ensuring the low temperature of the water, so that the workpiece can be quickly cooled and formed.

[0032] See also Figure 1 , 2As shown in 3, a guide rail 25 is fixedly connected between the No. 1 side plate 2 and the top of the No. 2 side edge 24, and the die 21 is slidably connected to the guide rail 25.

[0033] It should be noted that the guide rail 25 of the present invention is fixedly connected to the No. 1 side plate 2 and the No. 2 side edge 24, so as to increase the stability of both. In addition, the guide rail 25 is arranged in parallel with the sliding guide rod 3 and the base 1, so as to ensure the horizontal and stable movement of the die 21, so that the die 21 and the punch 8 can be accurately molded.

[0034] See also Figure 1 , 2 As shown in Figure 3, the demolding assembly includes a No. 1 hydraulic cylinder 5 fixedly connected to one side of the punch seat 4. The output end of the No. 1 hydraulic cylinder 5 passes through the punch seat 4 and is fixedly connected to a sliding plate 6. The sliding plate 6 is slidably arranged between the punch seat 4 and the punch 8 through a sliding rod. A plurality of ejector pins 7 are fixedly connected to one side of the sliding plate 6, and the ejector pins 7 are slidably connected to the punch 8.

[0035] It should be noted that, during demolding of the present invention, the output end of the No. 1 hydraulic cylinder 5 pushes the sliding plate 6 to slide to one side, and the sliding plate 6 drives the ejector pin 7 to slide to one side, so that the ejector pin 7 penetrates the punch 8 to lift the workpiece and separate it from the raised part of the punch 8. After the workpiece is removed, the No. 1 hydraulic cylinder 5 drives the ejector pin 7 to reset through the sliding plate 6, which is convenient for the next injection molding process.

[0036] See also Figure 1 , 2 As shown, a No. 3 hydraulic cylinder 23 is fixedly connected to one side of the No. 2 side edge 24 , and an output end of the No. 3 hydraulic cylinder 23 is fixedly connected to the die 21 .

[0037] It should be noted that the die 21 carried by the No. 3 hydraulic cylinder 23 of the present invention slides along the guide rail 25 , so that the die 21 and the punch 8 can be closed and separated by sliding the die 21 .

[0038] See also Figure 3 , 6 As shown in , 7, a sliding rod 10 is fixedly connected to one side of the material receiving trough 9, and the sliding rod 10 is slidably connected to the bottom of the punch seat 4. A return spring 11 is sleeved on the outside of the sliding rod 10 and located between the material receiving trough 9 and the punch seat 4. The top of the material receiving trough 9 and the outside of the piston plate 19 are fixedly connected to sealing rings. The top of the base 1 is fixedly connected to a material guide pipe 28 that cooperates with the material receiving trough 9, and one end of the material guide pipe 28 is detachably installed with a material receiving box 27.

[0039] It should be noted that, in the present invention, when the punch 8 is separated from the die 21, the return spring 11 pushes the material receiving groove 9 to move to one side of the punch 8, and the material receiving groove 9 drives the sliding rod 10 to slide at the bottom of the punch seat 4. At this time, the material receiving groove 9 is located on one side of the punch 8, so as to facilitate material receiving. When the punch 8 and the die 21 are molded together, the return push rod 12 pushes the material receiving groove 9 to move to one side, so that the material receiving groove 9 moves to the bottom of the punch seat 4. The top sealing ring of the material receiving groove 9 contacts the bottom of the punch seat 4, and the punch seat 4 blocks the material receiving groove 9 from the top, and the top of the material receiving groove 9 contacts the punch seat. 4 is slidably connected to the bottom of the receiving trough 9, the inner wall of the receiving trough 9 is provided with a guide groove, and the piston plate 19 is slidably connected to the guide groove to prevent the piston plate 19 from tilting and flipping under the action of the high-pressure gas, so that the piston plate 19 moves horizontally to one end. Under the action of the high-pressure gas, the receiving trough 9 and the piston plate 19 form a structure similar to that of a syringe. The piston plate 19 pushes the material inside the receiving trough 9 to the inside of the material guide pipe 28, and then enters the material receiving box 27 along the material guide pipe 28. After all the processing is completed, the material receiving box 27 is removed, and the cover on one side is opened to pour out the collected material.
