Abstract
The invention discloses a ceramic powder tabletting mold of for prostheses in the department of dentistry, and belongs to the field of forming molds of medical ceramic. The ceramic powder tabletting mold is composed of a lower punch, a female mold and an upper punch, and the shape of a tablet is a horseshoe and similar to that of all teeth in the mouth. The lower punch is in a horseshoe shape; the female mold is a cylinder provided with a horseshoe-shaped mold cavity, and the lower punch is sleeved with the female mold; the upper punch is divided into an upper portion and a lower portion, the upper portion of the upper punch is of a cylindrical structure, and the lower portion of the upper punch has the same shape as the lower punch. The ceramic powder tabletting mold can increase the utilization rate of ceramic blocks in a process of making all the teeth in the mouth, is simple in structure, reduces the number of working procedures, is easy to machine, can be made of common mold steel, and saves cost.
Description
Technical field
The invention belongs to medical ceramic mould scope, particularly a kind of dental prosthesis ceramic powder compression mold, relates in particular to a kind of profusely mould of the dental prosthesis ceramic powder compressing tablet of thread form shape of preparing.
Background technology
The application that dental prosthesis is processed into tooth profusely with ceramic block is more and more extensive.In existing technique, the ceramic block of preparation is the shapes such as discoid, cuboid mostly, prepares profusely odontodes to adopt discoid ceramic block, causes waste of material, and ceramic block utilization rate is low.Therefore, develop a kind of compression mold similar to thread form shape profusely, can reduce spillage of material, reduce manufacturing procedure, cost-saving, improve ceramic block utilization rate.
Summary of the invention
The object of this invention is to provide the compressing tablet shape a kind of dental prosthesis ceramic powder compression mold similar, simple in structure to tooth profusely, it is characterized in that, compressing tablet is shaped as the shape of a hoof, to profusely thread form shape is similar.Described ceramic powder compression mold is made up of low punch, die and upper punch three parts; Its low punch is shaped as the shape of a hoof; Its die is the cylinder with shape of a hoof impression, is sleeved on low punch; Upper punch is divided into upper and lower two parts, and the top of described upper punch is column structure (shape of a hoof, circle or polygon), and bottom is identical with low punch shape, the size of the horseshoe-shaped structure cross section of upper punch bottom and shape of a hoof impression cross section measure-alike; And the external dimensions of the column structure on upper punch top is slightly less than lower dimension, make to form certain gap with die impression, be beneficial to the demoulding.
The size of described shape of a hoof impression cross section and low punch cross section measure-alike.
The thickness sum of the height of described upper punch and low punch is greater than the degree of depth of die.
Described ceramic powder compression mold adopts common die steel to make.
The shape that the invention has the beneficial effects as follows compressing tablet of the present invention is the shape of a hoof, and shape of a hoof compressing tablet is similar to the profusely thread form shape of human body, therefore, can improve the utilization rate of ceramic block in the process that is processed into tooth profusely.Simple in structure, reduce manufacturing procedure, be easy to processing, utilize common die steel to make, cost-saving.

Detailed description of the invention
The invention provides a kind of dental prosthesis ceramic powder compression mold, below in conjunction with the drawings and specific embodiments, the present invention is elaborated.
In the overall structure schematic diagram of the compression mold shown in Fig. 1, compressing tablet is shaped as the shape of a hoof, to profusely thread form shape is similar.Described ceramic powder compression mold is made up of low punch 1, die 2 and upper punch 3 three parts; Its low punch 1 is shaped as the shape of a hoof; Die 2 is for having the cylinder of shape of a hoof impression 4, and the size of shape of a hoof impression cross section and low punch cross section measure-alike is sleeved on low punch 1; Upper punch 3 is divided into upper and lower two parts, utilizes common die steel to do.The top of described upper punch is column structure (shape of a hoof, circle or polygon), and bottom is identical with low punch shape, the size of the horseshoe-shaped structure cross section of upper punch bottom and shape of a hoof impression cross section measure-alike; And the external dimensions of the column structure on upper punch top is slightly less than lower dimension, make to form certain gap with die impression, be beneficial to the demoulding.The thickness sum of the height of described upper punch and low punch is greater than the degree of depth of die.
Embodiment
The thickness h of described shape of a hoof low punch 1
1=25mm, the radius R of two orthodromes
1=25mm, the radius of two small arc-shapeds is R
2=10mm, two the longest back gauge a=100mm, the distance b=60mm between symmetry axis and the intersection point on both sides.
The height h of described die 2
3=120mm, diameter of phi
1=150mm, the size size of horseshoe-shaped impression cross section is identical with horseshoe-shaped low punch 1.The minimum thickness e=25mm of die 2, maximum ga(u)ge f=45mm.
The horseshoe-shaped structure of described upper punch 3 bottoms is identical with the size of shape of a hoof low punch 1, and the upper Partial Height of upper punch 3 is h
2=100mm, length c=82mm, width d=48mm.The upper part of upper punch 3 can change, as long as meet the demands,
Make the operating procedure of shape of a hoof compressing tablet: take out upper punch 3, shape of a hoof low punch 1 is placed in to the bottom of die 2, claim a certain amount of ceramic powder, it is evenly laid on low punch 1, put into upper punch 3, evenly exert oneself, then be placed in and on tablet press machine, carry out compressing tablet, after compressing tablet has operated, carefully take out compressing tablet.
