Description

Technical Field

[0001] The invention belongs to the field of false tooth production, in particular to a tooth die-casting machine used for processing resin teeth and hard teeth. Background Art

[0002] Dentures are formed by pressure inside a mold. In order to complete the city-shaped manufacturing of teeth, a specific mold is required. The mold has specific pressure and temperature requirements when forming teeth. Pressing equipment is needed to pressurize and humidify. At the same time, the problem of how to add raw materials into the mold must also be considered.

[0003] At present, most companies in the industry still use the process of adding raw materials of resin teeth or hard teeth before the mold is closed, and pressing after the mold is closed; this process requires manual filling of dough-like raw materials into each cavity of many teeth in the mold one by one. This process is very inefficient and labor-intensive, and the raw materials will shrink in volume due to the polymerization reaction when the teeth are heated and pressurized. If there is no material replenishment after shrinkage, the product teeth will have pores, resulting in a decrease in the yield rate. Some companies make composite molds, that is, die-casting the raw materials from a designed space in the mold into another layer of the tooth cavity, but in this way, the mold is already heated during pressurization, and the raw materials (including resin) have already undergone polymerization reaction and hardened after heating, resulting in poor injection effect and also low yield rate.

[0004] The purpose of the present invention is to create a die-casting machine that meets the needs of industrial high-efficiency production of teeth, reduces labor intensity, improves production efficiency, and saves raw materials. Therefore, a tooth die-casting machine for resin teeth and hard teeth processing is proposed. Summary of the invention

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

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

[0031] Four columns 3 are evenly arranged between the lower fixed table 7 and the upper fixed plate 2. A heating block 9 is arranged between the sliding plate 4 and the lower fixed table 7. Two sliding sleeves 11 are fixedly arranged on the heating block 9. The sliding sleeves 11 are arranged at two diagonal corners of the heating block 9. The sliding sleeves 11 are slidably connected with the columns 3. A material box 12 is located above the heating block 9. A fixed plate 13 is respectively arranged on both sides of the material box 12. The material box 12 is slidably connected with the fixed plate 13. Two positioning rods 15 are respectively arranged on the fixed plate 13. The top of the positioning rod 15 passes through the sliding plate 4.

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

[0033] A hole 10 is provided in the middle of the heating block 9, and the diameter of the hole 10 is larger than the outer diameter of the mold 8 for forming teeth below the heating block 9. The mold 8 is placed on a placement frame above the lower fixed platform 7. The top end of the limit rod 6 is fixedly connected to the sliding plate 4. The bottom end of the limit rod 6 passes through the connecting plate at the edge of the heating block 9 and is threadedly connected to the limit nut. The limit nut is movably abutted against the connecting plate on the heating block 9. The limit rod 6 can pull up the heating block 9 through the limit nut when the sliding plate 4 rises.

[0034] The mold 8 is composed of an upper mold and a lower mold, and the upper mold and the lower mold are movably connected and can be used for die-casting teeth.

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

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

[0037] A limiting ring is provided on the top of the material box 12 , and the lower side of the limiting ring abuts against the upper side of the fixing plate 13 .

[0038] The specific implementation method is as follows: the hydraulic cylinder 1 drives the sliding plate 4 and the piston 5 to press down, the piston 5 presses into the material box 12 in which the raw material is placed in advance, and the material box 12 descends to contact the lower mold of the mold 8, at which time the hole below the material box 12 and the hole on the mold 8 will overlap correspondingly;

[0039] The raw material is put into the material box 12, and the piston 5 extends into the material box 12. The piston 5 squeezes the raw material in the material box 12 under pressure to reach the upper mold of the mold 8. The injected raw material is respectively wept into the mold cavity of each tooth through the specific sprue 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 plate 4. Since the hole 10 of the heating block 9 is larger than the outer diameter of the mold 8, the heating block 9 heats the mold at the outer circle of the mold at the same time, and the raw material in the mold also starts the polymerization reaction;

[0040] When the polymerization reaction volume shrinks, the material in the material box can be replenished and injected, which greatly improves the product qualification rate; after the injection process is completed, the hydraulic cylinder 1 pulls the sliding plate 4 and the piston 5 to rise; the heating block 9 also rises under the pull of the pull rod 6;

[0041] The lower material box frame 3 and the upper material box 12 also rise to the specified position under the pull of the spring 14, completing the whole process with this. After the mold is removed and the material is added again, the next repeated process is followed.

[0042] The raw materials are raw materials for resin teeth and hard teeth.

[0043] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
