Description

TECHNICAL FIELD

[0001] The present application belongs to the field of false tooth manufacturing, in particular to a die casting machine for tooth processing. BACKGROUND

[0002] False teeth are formed by pressure molding in a mold. To complete the molding of teeth, a special mold is needed. The mold requires a specific pressure and temperature when forming teeth. A press equipment is needed for pressing. Meanwhile, the mold needs to be humidified. How to add raw materials to the mold also needs to be considered.

[0003] At present, most enterprises in the industry still use the process of adding resin teeth or hard tooth raw materials before the mold is closed, and then pressing after the mold is closed. This process requires manual filling of dough-like raw materials into each cavity of the mold. The efficiency is low and the labor intensity is large. When the raw materials are heated and pressed to form teeth, the volume will shrink due to polymerization reaction. After shrinking, there is no material to supplement, which will cause the product teeth to have pores, resulting in a low yield. Some manufacturers make composite molds, which press the raw materials from a designed space in the mold into another layer of tooth cavity. However, the mold is heated when it is pressed. The raw materials (including resin) have already hardened after heating due to polymerization reaction, resulting in poor injection effect and low yield.

[0004] The purpose of the present application is to create a die casting machine that meets the needs of industrial high-efficiency tooth production, reduces labor intensity, improves production efficiency, and recycles and saves raw materials. CONTENT OF THE INVENTION

[0030] like Figure 1 As shown, the present invention proposes a die-casting machine for tooth processing, comprising: a column 3, a lower fixed platform 7, an upper fixed plate 2, an upper hydraulic cylinder 1, and a sliding pressure plate 4;

[0031] Four columns 3 are evenly arranged between the lower fixed platform 7 and the upper fixed plate 2. A heating block 9 is set between the sliding pressure plate 4 and the lower fixed platform 7.

The material box 12 is slidably connected to the fixed plate 13. Two positioning rods 15 are set on the fixed plate 13. The top of the positioning rods 15 passes through the sliding pressure plate 4.

[0032] The movable end of the upper cylinder 1 is fixedly connected to the middle part of the upper side of the sliding pressure plate 4.

[0033] A hole 10 is formed in the middle of the heating block 9, and the diameter of the hole 10 is greater than the outer diameter of a mold 8 for forming teeth below the heating block 9. The mold 8 is placed on a placing rack above a lower fixed table 7. The top end of a limiting pull rod 6 is fixedly connected with the sliding pressure plate 4, and the bottom end of the limiting pull rod 6 passes through a connecting plate at the edge of the heating block 9 and is threadedly connected with a limiting nut. The limiting nut is movably abutted with the connecting plate on the heating block 9. When the limiting pull rod 6 is lifted by the limiting nut, the heating block 9 can be lifted.

[0035] A spring 14 is sleeved on a positioning rod 15 connected between the material box 12 and the fixed plate 13.

[0036] The top end of the material box 12 is movably abutted with the bottom of the piston 5, and the piston 5 is fixedly connected with the middle part of the sliding pressure plate 4.

[0037] A limiting ring is arranged on the top of the material box 12, and the lower side of the limiting ring is abutted with the upper side of the fixed plate 13.

[0038] Specifically, the hydraulic cylinder 1 drives the sliding pressure plate 4 and the piston 5 to be pressed downward, the piston 5 is pressed into the material box 12 in which raw materials are placed in advance, the material box 12 is lowered to contact the lower mold of the mold 8, at this time, the hole below the material box 12 and the hole on the mold 8 will be correspondingly overlapped; the raw materials are placed in the material box 12, the piston 5 is inserted into the material box 12, the piston 5 extrudes the raw materials in the material box 12 under pressure to reach the upper mold of the mold 8, the injected raw materials are respectively injected into the cavities of the teeth through the specific injection channels in the mold, the lower mold of the mold 8 is covered on the upper mold of the mold 8, at this time, the heating block 9 also falls with the sliding pressure plate 4, because the hole 10 of the heating block 9 is greater than the outer diameter of the mold 8, the heating block 9 simultaneously heats the mold outside the mold, and the raw materials in the mold also start the polymerization reaction.

[0039] When the volume of the polymerization reaction shrinks, the material in the material box can be supplemented and injected, so that the product qualification rate is greatly improved; after the injection process is completed, the hydraulic cylinder 1 pulls the sliding pressure plate 4 and the piston 5 to rise; under the pulling of the pull rod 6, the heating block 9 also rises.
