Summary of the invention

In order to solve problems of the prior art, the object of this invention is to provide a kind of anti-demoulding tooth pallet.

The technical solution used in the present invention is as follows:

A kind of anti-demoulding tooth pallet, comprise the pallet being provided with overflowing hole, pallet is provided with handle away from one end of opening, it is characterized in that: be respectively equipped with base below the tray slot on the left and right both sides of described pallet, and it is for holding the modeling composition overflowed from overflowing hole.

Described one anti-demoulding tooth pallet, is characterized in that: described base is made up of base plate, the retaining wall being positioned at base plate periphery, the raised line being positioned at base plate inner circumferential and connecting plate; Left and right base plate is flexibly connected with pallet by screw in its connecting plate end.

Described one anti-demoulding tooth pallet, is characterized in that: the position that the outside of described pallet is corresponding with tray slot inner ring is provided with maintenance bar.

Described one anti-demoulding tooth pallet, is characterized in that: the junction of residing handle and pallet is provided with overflowing hole.

Described one anti-demoulding tooth pallet, is characterized in that: the aperture be positioned at inside pallet, described overflowing hole is less than the aperture in outside.

Structure of the present invention is simple, reasonable in design, there is following beneficial effect, (1) below pallet, base is set up, spacing certain between base and pallet, namely the die material overflowed from overflowing hole enters the cavity that base and pallet formed, thus define there is certain thickness drag die plane, for die takes out the strength that process and die filling process provide powerful opposing vertical and lateral displacement and deformation, also decrease die material simultaneously dramatically and be extruded to cause in the mouth of patient nauseating or other are uncomfortable.2) pallet overflowing hole be designed to the design little compared with the diameter of pallet apertura lateralis of pallet inside diameter, like this in die taking-up process, prevent modeling composition from dislocating from pallet, increase frictional force and retention.3) with in common pallet delivery process, doctor's both hands forefinger is by being pressed in the middle part of pallet both sides pallet to be fixed on a settling position, modeling composition cannot be discharged due to blocking of forefinger in the overflowing hole of forefinger position, because not having the card of pallet to modeling composition to embrace power herein, so it is more weak to locate anti-die dislocation power.Be very easy to dislocation herein when die takes out, but the finger maintenance district of this device doctor is covered by base, therefore the discharge that can not affect overflowing hole die material and the die type plane formed thereof, enhance drag performance herein.4) traditional tray handle and tray body weld, there is no overflowing hole, when die takes out in oral cavity and when mould filled with by die modeling composition easily and pallet depart from, cause stamp deformation, this pallet still designs overflowing hole at handle and tray body weld, adds the anti-anticreep virial of junction.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described in detail.

Anti-demoulding tooth pallet designed by the present invention is the improvement carried out on the basis of existing tooth pallet.Existing tooth pallet comprises pallet 1, and be provided with handle 3 at pallet 1 away from one end of opening, pallet 1 is provided with overflowing hole 8, welds between pallet 1 with handle 3, handle 3 is solid with the weld of pallet 1, does not namely establish overflowing hole 8.Very easily there is demoulding in this pallet, especially at tray slot place.In order to solve this problem, the present invention improves on the basis of existing technology, the position of improving mainly contains: below the tray slot on the left and right both sides of pallet 1, set up base 2 respectively, form both wings, base 2 is made up of base plate, the retaining wall 4 being positioned at base plate periphery, the raised line 5 being positioned at base plate inner circumferential and connecting plate 6; Because there is certain distance between base 2 and tray slot, therefore the modeling composition in pallet can overflow from overflowing hole 8 after extruding with denture, namely the die material overflowed enters in the cavity between base 2 and tray slot, namely a die material plane is formed, die material in this plane and pallet 1 connects into an entirety by the die material at overflowing hole 8 place, add the retention intensity of die material in pallet, thus serve the effect of anti-demoulding.The connecting plate end of left and right two bases 2 is provided with aperture, and in aperture, assembling screw 9, is rotationally connected by screw 9 and pallet 1.
