Injection molding is a processing method used in mass production of some complex-shaped parts. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, a formed product is obtained.

[0003] However, the existing injection molds can only mold products, and cannot make the upper mold have a stable movement trend during lifting, resulting in jamming of the upper mold during movement due to the friction with the outer wall, which affects the injection quality.

A transmission mechanism is fixedly connected to the lower output end of the electric telescopic rod. Rolling mechanisms are symmetrically and fixedly connected to the front and rear of the left and right parts of the transmission mechanism.

[0009] Preferably, the transmission mechanism includes a transmission plate. At the left and right ends of the outer surface of the transmission plate, T-shaped blocks are symmetrically and fixedly connected. At the left and right ends of the outer surface of the transmission plate, rectangular grooves communicating with the outside are symmetrically formed in the front and rear directions. In the middle of the lower end of the outer surface of the transmission plate, an annular groove communicating with the outside is formed. And the two T-shaped blocks are respectively slidably connected to the inner cavities of the corresponding T-shaped chutes.

The two guiding mechanisms 3 are jointly and fixedly connected to the top plate 4 at the top. In the middle of the upper end of the outer surface of the top plate 4, an electric telescopic rod 5 is installed and fixed. The lower output end of the electric telescopic rod 5 is fixedly connected with a transmission mechanism 6, which can drive the connection mechanism 8 to move up and down. On the front and back sides of the left and right parts of the transmission mechanism 6, rolling mechanisms 7 are symmetrically and fixedly connected, which can reduce the friction suffered by the outside of the transmission mechanism 6. The middle lower side of the transmission mechanism 6 is movably connected with a connection mechanism 8, which can facilitate the disassembly and replacement of the male die assembly 9. The lower part of the connection mechanism 8 is fixedly connected with a male die assembly 9, which can cooperate with the female die assembly 2 to shape plastic products.

[0023] To achieve the purpose of shaping plastic products in cooperation with the male die assembly 9, refer to Figure 2, the female die assembly 2 includes a first fixing plate 21. In the middle of the lower end of the outer surface of the first fixing plate 21, a semi-circular strip 22 is fixedly connected, which can play a role in guiding the movement of the lower die 24. At the four corners of the upper end of the outer surface of the first fixing plate 21, pin 23s are slidably connected, which can play a role in locking the position of the sealing groove 25. In the middle of the upper end of the outer surface of the first fixing plate 21, a lower die 24 is fixedly connected. On the upper end of the outer surface of the lower die 24, a sealing groove 25 communicating with the outside is opened.

[0024] For the purpose of guiding the movement of the transmission mechanism 6, refer to Figure 2 , the guiding mechanism 3 includes a support plate 31. At one end of the outer surface of the support plate 31 away from the middle of the base 1, a T-shaped sliding groove 32 communicating with the outside is opened, which can play a role in guiding the movement of the transmission plate 61. At the front and back of one end of the support plate 31 close to the middle of the base 1, limiting grooves 33 communicating with the outside are symmetrically opened, which can play a role in guiding and limiting the movement of the corresponding rotating rollers 72.

[0025] For the purpose of driving the connecting mechanism 8 to perform lifting movement, refer to Figure 3 , the transmission mechanism 6 includes a transmission plate 61. At the left and right ends of the outer surface of the transmission plate 61, T-shaped blocks 62 are symmetrically fixedly connected, which can play a role in guiding the lifting movement of the transmission plate 61. At the left and right ends of the outer surface of the transmission plate 61, rectangular grooves 63 communicating with the outside are symmetrically opened at the front and back. In the middle of the lower end of the outer surface of the transmission plate 61, an annular groove 64 communicating with the outside is opened, which can play a role in clamping and locking the connecting column 81. And the two T-shaped blocks 62 are respectively slidably connected to the inner cavity of the corresponding T-shaped sliding groove 32. The middle of the upper end of the outer surface of the transmission plate 61 is fixedly connected to the lower output end of the electric telescopic rod 5.

[0026] For the purpose of reducing the friction suffered by the outside of the transmission mechanism 6, refer to Figure 3 , the rolling mechanism 7 includes a fixed shaft 71. A number of rotating rollers 72 are rotatably connected at intervals on the outer surface of the fixed shaft 71, which can play a role in reducing the large amount of friction generated between the outer surface of the transmission plate 61 and the inner walls of the two support plates 31. And the fixed shaft 71 is fixedly connected to the side wall of the inner cavity of the corresponding rectangular groove 63.

[0027] For the purpose of facilitating the disassembly and replacement of the male die assembly 9, refer to Figure 4 , the connecting mechanism 8 includes a connecting column 81. A number of arc-shaped blocks 82 are fixedly connected in an annular array on the upper part of the outer surface of the connecting column 81. Tightening screws 83 are threadedly connected in the inner cavities of the number of arc-shaped blocks 82. And the number of arc-shaped blocks 82 are rotatably connected to the inner cavity of the annular groove 64.

[0028] When it is necessary to disassemble and replace the second fixing plate 91, first rotate and remove a number of fastening screws 83, and then drive the connecting column 81 to rotate within a certain range in the inner cavity of the annular groove 64 by rotating the second fixing plate 91. When a number of arc-shaped blocks 82 are aligned with the outlet of the annular groove 64, the connecting column 81 can be taken out from the inner cavity of the annular groove 64 to disassemble the connecting column 81.

[0029] To achieve the purpose of shaping plastic products in cooperation with the female die assembly 2, refer to Figure 3 , the male die assembly 9 includes a second fixing plate 91. The lower end of the outer surface of the second fixing plate 91 is fixedly connected with an upper die 92. The lower end of the outer surface of the upper die 92 is fixedly connected with a sealing strip 93, which can achieve the effect of making the upper end of the outer surface of the lower die 24 and the lower end of the outer surface of the upper die 92 in a sealed state after being clamped into the inner cavity of the sealing groove 25. And the middle part of the upper end of the outer surface of the second fixing plate 91 is fixedly connected with the lower end of the outer surface of the connecting column 81.

[0030] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic rod 5 in the present invention are all conventional designs, and the present invention will not be elaborated in detail.

[0031] The working principle of the present invention: By driving the electric telescopic rod 5 to push the transmission plate 61 downward, at this time, two T-shaped blocks 62 will move downward synchronously with the transmission plate 61 in the corresponding T-shaped sliding grooves 32, and a number of rotating rollers 72 will roll on the inner surface of the corresponding limiting grooves 33 until the sealing strip 93 is completely clamped into the inner cavity of the sealing groove 25. When it is necessary to replace the upper die 92, first rotate and remove a number of fastening screws 83, and then rotate the second fixing plate 91 to drive the connecting column 81 to rotate in the inner cavity of the annular groove 64. When a number of arc-shaped blocks 82 are aligned with the outlet of the annular groove 64, the connecting column 81 can be taken out from the inner cavity of the annular groove 64. When it is necessary to replace the lower die 24, first pull out a number of pins 23 upward, and then slide the lower die 24 out from the upper end of the outer surface of the base 1. During this period, the lower die 24 will drive the semi-circular strip 22 to slide back and forth in the inner cavity of the semi-circular groove 11 to guide the movement of the lower die 24.
