Description

Technical Field

[0001] The utility model belongs to the technical field of hot pressing molding, in particular to a hot pressing molding device for a dental mold. Background Art

[0002] Thermoforming is a molding technology that uses a plastic material membrane in the dental field to make a patient's dental mold. The dental mold can be used to correct tooth position and bite. It can correct the arrangement of teeth, improve the bite function, and to a certain extent improve the aesthetic appearance of the oral cavity.

[0003] The current hot pressing method generally heats and softens the diaphragm, and then relies solely on pressure to press the softened diaphragm onto the mold to shape it. The pressed dental diaphragm cannot fit the mold completely, and the pressing and shaping effect is poor. For this reason, we propose a hot pressing molding device for dental molds. Utility Model Content

A connecting pipe is installed on the side wall of the connecting column. The connecting pipe, the connecting column and the inner cavity of the placement plate are communicated. A vacuum pump is also provided in the mounting seat, and a connecting pipe 1 is connected between the vacuum pump and the connecting pipe. A mounting cover is provided above the placement plate, and a column is connected between the mounting cover and the mounting seat. A diaphragm clamp is installed at the lower part of the mounting cover, and the diaphragm clamp can be used to clamp a diaphragm. A fan is provided in the mounting cover, and a heating tube is provided between the fan and the diaphragm clamp.

[0005] Preferably, the lift can be a hydraulic lift, the telescopic end of the lift is fixedly connected to the bottom of the connecting column, and the telescopic end of the lift can drive the placement plate to rise and fall through the connecting column.

[0006] Preferably, the placement plate is disc-shaped, the diaphragm clamp is ring-shaped, the diameter of the inner wall of the diaphragm clamp is greater than or equal to the diameter of the placement plate, and the placement plate can be inserted into the diaphragm clamp when it is raised.

[0007] Preferably, the diaphragm clamp includes a fixed clamp, a movable clamp, a rotating shaft and a buckle. The fixed clamp is installed at the bottom of the mounting cover. The movable clamp is rotatably connected to the bottom of the fixed clamp through the rotating shaft. The buckle is arranged between the fixed clamp and the movable clamp. Locking / opening the buckle can prevent / allow the diaphragm clamp to open.

[0008] Preferably, the heating tube is arranged parallel to the diaphragm clamp, and the air outlet of the fan is downward and perpendicular to the heating tube. The fan can blow the heat generated by the heating tube toward the diaphragm, so that the diaphragm is softened by the heat.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] Place the mold on the placement plate, open the buckle, open the movable clamp downward, place the diaphragm between the movable clamp and the fixed clamp, rotate the movable clamp upward to clamp the diaphragm between the movable clamp and the fixed clamp, lock the buckle to prevent the movable clamp from opening, and then turn on the heating tube to preheat the heating tube, and then turn on the fan. The fan blows the heat generated by the heating tube to the diaphragm to soften the diaphragm. When the diaphragm is heated and softened to a suitable state, turn off the heating tube, start and control the extension of the telescopic end of the elevator, and then lift the placement plate to drive the mold to rise, and insert the mold The diaphragm is inserted into the diaphragm clamp, and the diaphragm deformed by heat will be pressed to the surface of the mold. Then the vacuum pump is started. The suction generated by the vacuum pump adsorbs the diaphragm to the mold surface through the connecting tube and the through-holes on the placement plate. At the same time, the wind generated by the fan blowing towards the diaphragm also helps to make the diaphragm fit the mold. After hot pressing for a period of time, it can be formed. The fan and vacuum pump are turned off respectively, and then the elevator is reset by controlling it. The dental mold can be removed by opening the buckle, thereby making the diaphragm fit the mold better, thereby achieving a better dental mold restoration effect and improving the efficiency of hot pressing.
