Detailed implementation manners

[0020] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in conjunction with the embodiments.

[0022] Refer to Figures 1-4 , this embodiment provides a plastic model molding machine for plastic mold production, including a bottom plate 1, a support frame 2 is fixedly connected above the bottom plate 1, a first mold 3 is arranged on the inner surface of the support frame 2, rotating rods 4 are fixedly connected to the front and back sides of the first mold 3, the rotating rods 4 penetrate and are rotatably connected to the inner surface of the support frame 2, a second mold 5 is arranged on the right side of the first mold 3, an injection port is arranged above the second mold 5, a pushing assembly 6 is arranged below the second mold 5, the pushing assembly 6 includes a slide rail 601, the slide rail 601 is fixedly connected above the bottom plate 1, a sliding seat 602 is slidably connected above the slide rail 601, a chute is arranged below the sliding seat 602 for sliding on the slide rail 601, the sliding seat 602 is fixedly connected to the lower part of the second mold 5, a hydraulic push rod 603 is fixedly connected to the right side of the sliding seat 602, the number of the hydraulic push rod 603 and the slide rail 601 is two, the right end of the hydraulic push rod 603 is fixedly connected to a support plate 604, the support plate 604 is fixedly connected above the bottom plate 1, pushing seats 605 are fixedly connected to the front and back sides of the sliding seat 602, the shape of the pushing seat 605 is L-shaped, teeth 606 are fixedly connected above the pushing seat 605, the teeth 606 are only a small section, when the first mold 3 is vertical and there is still a certain distance between the first mold 3 and the second mold 5, the teeth 606 will completely pass through the gear 607, at this time the gear 607 can rotate, the pushing assembly 6 further includes a gear 607, the gear 607 is fixedly connected to the outer surface of the rotating rod 4, the number of the gear 607, the teeth 606 and the pushing seat 605 is two, and they are symmetrically arranged on the front and back sides of the sliding seat 602 respectively, and the gear 607 meshes with the teeth 606 above.

[0023] When the above-mentioned device is used, the first mold 3 and the second mold 5 are in an open state under normal conditions to facilitate the removal of the plastic model after shaping. When the first mold 3 and the second mold 5 need to be closed, the hydraulic push rod 603 is first started to extend it, and the hydraulic push rod 603 pushes the sliding seat 602 to slide leftward on the slide rail 601, so that the second mold 5 approaches the first mold 3. At this time, as the sliding seat 602 slides leftward, the teeth 606 on the pushing seat 605 on the sliding seat 602 will shift the gear 607 to drive the rotating rod 4 to rotate clockwise, and the clockwise rotation of the rotating rod 4 will drive the first mold 5 to move closer to the first mold 3. A mold 3 is flipped upward until it stands up. At this time, the first mold 3 is vertical and there is still a distance between it and the second mold 5, but the tooth 606 has passed the gear 607. The gear 607 loses its support, and the rotating rod 4 can drive the first mold 3 to rotate. At this time, the first mold 3 will fall toward the second mold 5 and lean on it. The hydraulic push rod 603 is continued to be started to drive the sliding seat 602 to slide to the left, so that the second mold 5 pushes against the first mold 3 to make it stand up slowly until it is completely vertical and fits on the second mold 5. At this time, plastic is injected through the injection port on the second mold 5 to facilitate shaping of the plastic model.

[0024] See also Figures 1-4 On the basis of the first embodiment, a support assembly 7 is arranged above the support frame 2, the support frame 2 is U-shaped, the support assembly 7 includes a top plate 701, the top plate 701 is rotated and elastically connected to the front of the first mold 3 through a torsion spring 702, the torsion spring 702 will apply a torsion force under normal conditions to flip the top plate 701 toward the top block 703, the support assembly 7 also includes a top block 703, the top block 703 is bolted to the front of the first mold 3, the top block 703 can be removed from the first mold 3, and the top block 703 is connected to the top block 703. The right side of the top plate 701 is movably fitted, and the top block 703 is used to support the right side of the top plate 701. A pushing assembly 8 is arranged under the top plate 701. The number of the supporting assembly 7 and the pushing assembly 8 is two groups, which are symmetrically arranged on the front and back sides of the first mold 3. The pushing assembly 8 includes an electric push rod 801, and the electric push rod 801 is fixedly connected to the right side of the support frame 2. The right end of the electric push rod 801 is fixedly connected to the pushing frame 802. As the first mold 3 is flipped, it can drive the top plate 701 to pass over the pushing frame 802.

[0025] When the above-mentioned equipment is used in practice, when the first mold 3 is flipped upward to stand up, the top plate 701 on the first mold 3 will first contact the ejector frame 802. At this time, the top plate 701 will flip under the action of the torsion spring 702 until it passes over the ejector frame 802 as the first mold 3 flips. When the second mold 5 is fitted with the first mold 3, the ejector frame 802 is pushed to the right by starting the electric push rod 801. The ejector frame 802 will push the top plate 701 and then push the ejector block 703, so that the first mold 3 and the second mold 5 are tightly fitted and fixed, so as to facilitate shaping of the plastic model. When the shaping is completed and the plastic model needs to be taken out, the ejector block 703 is first removed. At this time, the hydraulic push rod 603 is started to shrink it to drive the second mold 5 away from the first mold 3. The first mold 3 will also be knocked down in the process of the second mold 5 moving away until the first mold 3 and the second mold 5 are fully opened, so as to facilitate the removal of the plastic model after shaping.
