Abstract

The utility model relates to an invisible false tooth molding machine which can fast cast the raw material into the die and is with a processing high finished product ratio. The invisible false tooth molding machine includes a support consisting of an upper plate and a lower plate and a heating furnace. A die flask is put in the space between the upper plate and the lower plate. A rod which can move up and down is set on the heating furnace. One end of the lever is articulated with the bracket. The upper end is assembled with the position close to the articulated point to form extrusion lever mechanism. The extrusion action to the raw material box of the extrusion rod can be finished quickly only when the suspension end of the lever is forced downwards, which means the molding process is finished.

Description

The invisible false tooth make-up machine

Technical field

The utility model relates to a kind of manufacturing equipment of dental prosthetic articles for use, specifically is exactly the single lead screw ex truding briquetting machine of invisible false tooth.

Background technology

Available technology adopting has elasticity, the dummy that the dental prosthetic material that simulated effect is good is made is subjected to oral cavity odontopathy patient's favorable comment, this dummy does not have injury to oral cavity tissue, can not injure base (very) tooth yet, the existing extrusion equipment of making this invisible false tooth in the prior art, equipment mainly comprises by last, the support that following two boards body constitutes, be used to place raw materials furnace and heating above the upper plate body, on, there is column to connect around the following two boards body, on, mould is placed at position, space between the following two boards body, feeding mouth on the mould aligns with the feeding mouth at upper plate body middle part, raw material be arranged in round barrel shape heating furnace heating chamber and contact with upper plate body, the top of heating furnace is provided with a screw mandrel, the screw mandrel top is connected with a handle, screw mandrel rotates and moves up and down during rotary handle, move down and push the columniform pressure ram in the heating chamber of heating furnace, again by pressure ram extruding raw material box, at last raw material is expressed to in-mold molding, because screw mandrel is realized moving up and down in rotation process, its speed that moves up and down is very slow, especially the speed that moves down is crossed and is made that slowly the injection rate of raw material is too slow, because the temperature of raw material descends rapidly after entering mould, in order to remedy the fast problem of cooling, need heat to the mould flask in advance, and because the dies cavity the selection of material is limit, must slowly carry out heating of mould, be heated to 100 ℃ from normal temperature, reach 30～60 minutes heat time heating time, have a strong impact on the working (machining) efficiency of invisible false tooth so on the one hand, in addition, heating need be to last, the lower body heating has consumed a large amount of electric energy, although adopted the compensation method of heating, the slow-footed essential defect that is cast into of raw material does not overcome, thereby causes yield rate low; In order to provide enough extruding forces to guarantee that raw material box is broken by crowded, in fact the volume of screw mandrel and handle component is all huger.

Technology contents

The purpose of this utility model just provides and a kind ofly can fast raw material be cast into mould, invisible false tooth make-up machine that the processed finished products rate is high.

For achieving the above object, the utility model has adopted following technical scheme: a kind of invisible false tooth make-up machine, it comprises the support that is made of upper and lower two boards body, place raw materials furnace and heating above the upper plate body, there is column to connect around the upper and lower two boards body, mould is placed at position, space between the upper and lower two boards body, it is characterized in that: the body of rod that the top of heating furnace has an above-below direction to move, one end of lever links to each other with frame is hinged, and the upper end of the body of rod cooperates formation squash type leverage with the position of the close hinged point of lever.

As shown from the above technical solution, the mould flask is in place, treat that raw material finishes heating in heating furnace, as long as downwards the end that suspends of lever is exerted oneself, because lever principle, to obtain a pressure that amplifies several times or tens times on the body of rod, finish the action of pressure ram extruding raw material box rapidly, especially the speed that moves down is fast to make that the injection rate of raw material is very fast, although there is cooling to occur behind the material injecting mould flask in theory, because cooling extent is very little really, under the situation of the flowability that does not almost slacken raw material, the casting mold process promptly comes to an end, and therefore, the utlity model has the yield rate height, the remarkable advantage that working (machining) efficiency is high.
