[0002] An injection molding machine is mainly a type of equipment for plastic injection molding. It is a special process that injects and cools hot plastics and plastic stock through a molding mold. Injection molding machines can be divided into vertical, all-electric and horizontal types, etc. They can apply high pressure to molten plastic to fill the mold cavity after it is ejected. However, the existing vertical injection molding machines still have defects in the process of feeding raw materials through the slide mechanism. For example, the slide mechanism of the existing vertical injection molding machine is a direct sliding fit of two steel plates after nitriding treatment, and is powered by a hydraulic cylinder. During long-term operation, the two steel plates will be out of sync, and the sliding steel plate will deviate, thereby affecting processing and production. Utility Model Content

[0016] like Figure 1 to Figure 4 As shown, the utility model is a slide mechanism for a vertical injection molding machine, comprising a frame 1 and a workbench 2 mounted on the frame 1, a movable slide 3 and a fixed slide 4 arranged up and down are mounted on the workbench 2, a slide track 5 is arranged at the side end of the fixed slide 4, both ends of the bottom of the movable slide 3 are fixedly connected with an L-shaped guide seat 6 by bolts, the guide seat 6 is slidably assembled on the slide track 5, a servo motor 7 for driving the movable slide 3 to move along the length direction of the fixed slide 4 is mounted on the frame 1, a rack 8 is arranged in the length direction of the fixed slide 4, and a gear 9 transmission-connected to the rack 8 is mounted on the bottom surface of the movable slide 3.

[0017] There are two groups of fixed slides 4, and the two guide seats 6 are respectively slidably connected to the sliding rails 5 at the side ends of the two groups of fixed slides 4; the servo motor 7 is connected to the screw rod 10, and the screw nut 11 on the screw rod 10 is connected to the movable slide 3. The screw rod 10 is installed on the workbench 2 between the two groups of fixed slides 4. The servo motor 7 and the screw rod 10 provide power, which can improve the repeated positioning of the movable slide 3 sliding in and out, and achieve high synchronization and precise position coordination.

[0018] The bottom surface of the movable slide plate 3 is provided with a plurality of wear-resistant copper plates 12, and the bottom surface of the wear-resistant copper plates 12 is in contact with the fixed slide plate 4. By providing the wear-resistant copper plates 12, the wear resistance between the movable slide plate 3 and the fixed slide plate 4 can be effectively improved, and the processing cost can be reduced.

[0019] A lifting cylinder 13 is installed on the frame 1. In the figure, the connection diagram between the lifting cylinder 13 and the frame 1 is not further shown. The lifting cylinder 13 is connected to the ejector pin 14, and the ejector pin 14 is located below the fixed slide plate 4. The fixed slide plate 4 and the corresponding movable slide plate 3 are provided with a pin hole 15 corresponding to the ejector pin 14. After the movable slide plate 3 slides out, the lifting cylinder 13 drives the ejector pin 14 to rise. After the ejector pin 14 passes through the pin hole 15 on the fixed slide plate 4 and the corresponding movable slide plate 3, the product placed on the movable slide plate 3 can be easily ejected through the ejector pin 14, thereby effectively preventing the movable slide plate 3 from moving upward when the product is taken out.

[0020] A vertical guide column 16 is mounted on the frame 1, a lifting cylinder 17 is mounted on the frame 1, the guide column passes through the workbench 2, and the lifting cylinder 17 is connected to the workbench 2. The lifting cylinder 17 and the vertical guide column 16 cooperate to enable the workbench 2 to be lifted up and down.

[0021] In the utility model, the screw rod 10 and the servo motor 7 work together to drive the movable slide plate 3 on which the product (not shown in the figure) is placed to slide in and out. Furthermore, during the injection molding feeding process, after the movable slide plate 3 slides out to the set position, the ejector pin 14 rises and passes through the avoidance pin hole 15, so that the product on the movable slide plate 3 can be effectively ejected. At this time, the guide seat 6 and the arranged gear 9 and rack 8 cooperate with each other to avoid the problem of twisting and deviation during the sliding process of the movable slide plate 3, and the synchronization is high, and precise position coordination can be achieved. In addition, the guide seat 6 and the wear-resistant copper plate 12 are set, and the load-bearing and pressure-resistant capacity of the movable slide plate 3 can also be further improved.
