DETAILED DESCRIPTION
[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0019] A polymer plastic material injection molding device, such as Figures 1-4As shown, it includes a workbench 1, a first mold 2, a feed port 3, a support frame 4, a motor 5, a screw 6, a second mold 7, a guide rod 8, an ejector frame 9, a first telescopic spring 10, an air inlet pipe 11, a slide rod 12, a plug 13, a second telescopic spring 14 and a limiting frame 15. The upper right side of the workbench 1 is connected to the first mold 2, the right side of the first mold 2 is connected to the feed port 3, the upper left side of the workbench 1 is connected to the support frame 4, the left side of the support frame 4 is connected to the motor 5, the output shaft of the motor 5 is connected to the screw 6, the screw 6 is rotatably connected to the support frame 4, the second mold 7 is threadedly connected to the screw 6, and the left side of the second mold 7 is connected to three guide rods. 8. The guide rods 8 are all slidably connected to the support frame 4. The second mold 7 is slidably connected to the ejector frame 9. The ejector frame 9 is a hollow structure. Two first telescopic springs 10 are connected between the ejector frame 9 and the second mold 7. The ejector frame 9 is slidably connected to the support frame 4. The left side of the ejector frame 9 is connected to the air intake pipe 11. The upper and lower parts of the ejector frame 9 are slidably connected to the slide rod 12. The slide rod 12 is connected to the ejector frame 9 with a second telescopic spring 14. The right side of the slide rod 12 is connected to a plug 13. The left side of the middle of the support frame 4 is connected to the upper and lower limiting frames 15. The slide rods 12 are squeezed together with the adjacent limiting frames 15, and the limiting frames 15 are all L-shaped structures.
[0020] When using the utility model, first place the workbench 1 in the injection molding area of the polymer plastic material, then start the motor 5 on the support frame 4, so that the screw rod 6 rotates, and the second mold 7 moves to the right under the action of the thread, and the guide rod 8 guides the movement of the second mold 7, so that the second mold 7 contacts and closes with the first mold 2, and then the polymer plastic material is injected into the space between the second mold 7 and the first mold 2 through the feed port 3 for cooling and molding. After the polymer plastic material is molded, start the motor 5 in reverse, so that the second mold 7 moves to the left, so that the second mold 7 is away from the first mold 2, and the ejector frame 9 moves to the left. Through the extrusion fit between the ejector frame 9 and the support frame 4, the ejector frame 9 slides to the right relative to the second mold 7, and the first telescopic spring The spring 10 is squeezed and contracted, and the polymer plastic material formed on the second mold 7 is ejected. Then, driven by the second mold 7, the ejection frame 9 continues to move to the left, driving the slide bar 12 to move to the left. When the slide bar 12 contacts the limiting frame 15, the limiting frame 15 squeezes the slide bar 12 to slide, and the second telescopic spring 14 is squeezed and contracted, causing the slide bar 12 to move to the right on the ejection frame 9, causing the plug 13 to slide and eject the polymer plastic material stuck to the ejection frame 9. At the same time, air is blown through the air inlet pipe 11 to blow the polymer plastic material off the plug 13 and collect it to complete demoulding, thereby facilitating the demoulding of the injection-molded polymer plastic material, preventing the polymer plastic material from adhering to the mold again, and improving the processing efficiency.
