Abstract

The utility model relates to a making apparatus for artificial tooth moulds. The making apparatus for artificial tooth moulds comprises a containing chamber is arranged in the making apparatus for artificial tooth moulds. The making apparatus for artificial tooth moulds is characterized in that the position corresponding to a bolt of an original tooth mould in the containing chamber is provided with a containing groove drawn round by a ring wall. Soft wax filling material which is easy to separate is filled in the containing groove, so that the filling material is easy to separate when a gypsum bottom mould is separated from the making apparatus for artificial tooth moulds to make the bolt exposed, and drilling for exposing the bolt is not required. The utility model has the advantages of less procedure and high work efficiency. Environmental pollution and physical damage caused by the powder dust of gypsum are overcome.

Description

The fixture of artificial tooth bed die

This utility model relates to a kind of fixture of artificial tooth bed die.

Artificial tooth mfg. moulding die commonly used as shown in Figure 1-Figure 3, former tooth mould 9 is provided with pin 91 in a platform tooth root portion of the artificial tooth that need are mended, be provided with the room 93 of corresponding former tooth mould 9 in the fixture 92 of bed die, its manufacture method is to insert in the room 93 of bed die tool 92 behind former tooth mould 9 and the pin 91 coating off-shape agents, because in the room 93 or the premixing Gypsum Fibrosum arranged, after treating the dry sclerosis of Gypsum Fibrosum, insert in the room 93 of bed die fixture 92 owing to fill the premixing Gypsum Fibrosum in the container 93, treat that Gypsum Fibrosum is dry after, form Gypsum Fibrosum bed die 94, as shown in Figure 2, then take off the Gypsum Fibrosum bed die 94 at artificial tooth position, by artificial tooth adjacent position cutting and separating line, reach rotary-cut hole, the back side by Gypsum Fibrosum bed die 94, the root of pin 91 is exposed, as shown in Figure 3, because former tooth mould 9 and pin 91 coating off-shape agents, can take off propping up platform tooth 95, carry out follow-up molding flow process.The major defect of above-mentioned fixture 92 is: because Gypsum Fibrosum bed die 94 is opaque structure, pin 91 is embedded in the Gypsum Fibrosum the inside, judges that the accurate position of its pin is relatively more difficult; And will use abrasive drill when turnery is holed, cause the Gypsum Fibrosum dust from flying, contaminated environment need constantly be removed the Gypsum Fibrosum dust with spray gun or clear water, and operation is inconvenient, and efficient is lower.

The purpose of this utility model is to provide a kind of fixture of artificial tooth bed die, is provided with the storage tank that ringwall surrounds in the room of fixture, makes the pin on the Gypsum Fibrosum bed die exposed, overcomes the drawback of prior art, and reaching does not need the purpose of holing and raising the efficiency.

The purpose of this utility model is achieved in that a kind of fixture of artificial tooth bed die, is included in to be provided with room in the fixture, it is characterized in that: the pin position of corresponding former tooth mould is provided with the storage tank that ringwall surrounds in this room.

The bottom land of this storage tank is wider than notch.

The bottom land of this storage tank is provided with the groove or the matsurface of dovetail shape.

Fill soft wax in the storage tank of this fixture.

Major advantage of the present utility model is: owing to be provided with the storage tank that ringwall surrounds in the room of fixture, wherein fill and be easy to isolating soft wax inserts, when making the Gypsum Fibrosum bed die and the fixture demoulding, very easily separate inserts, it is exposed that pin is formed, and do not need boring to expose pin, significantly reduced operation, increase work efficiency, and overcome the Gypsum Fibrosum dust to the pollution of environment and to the injury of health.

Below in conjunction with preferred embodiment and accompanying drawing this utility model is further specified:

Fig. 1 is the decomposing schematic representation of former tooth mould commonly used and fixture;

Fig. 2 is the schematic perspective view of common gypsum bed die;

Fig. 3 is the schematic perspective view that takes off a platform tooth commonly used;

Fig. 4 is a fixture organigram of the present utility model (broken section);

Fig. 5 is a tooth mold forming generalized section of the present utility model;

Fig. 6 takes off the schematic perspective view of a platform tooth for this utility model;

Consult Fig. 4-Fig. 6, this utility model is included in and is provided with room 11 in the fixture 1, it is characterized in that: pin 91 positions of corresponding former tooth mould 9 are provided with the storage tank 13 that ringwall 12 surrounds in this room 11, the bottom land of this storage tank 13 is wider than notch, and the bottom land of this storage tank 13 is provided with the groove 14 or the matsurface of dovetail shape.

When making the artificial tooth bed die with this utility model, in the storage tank 13 of fixture 4, fill packing materials 2 such as soft wax earlier, then in room 11, fill Gypsum Fibrosum 3, on former tooth mould 9 and pin 91, be coated with off-shape agent, again pin 91 is inserted packing material 2 down, the baseplane and the Gypsum Fibrosum 3 of former tooth mould 9 are fitted, after Gypsum Fibrosum 3 dries up, when drawing on former tooth mould 9 little application of forces, formation is combined with the Gypsum Fibrosum bed die 4 of former tooth mould 9, after the Gypsum Fibrosum bed die 4 and fixture 1 demoulding, removes packing materials 2 such as soft wax, ring groove 41 is formed on the bottom at Gypsum Fibrosum bed die 4, pin 91 exposes in groove 41, and take off a convenient required platform tooth 5 is cut apart with adjacent tooth, carries out follow-up manufacturing artificial tooth flow process again, its subsequent flows journey is a prior art, so do not describe in detail.
