Abstract

The utility model relates to a mould equipment field especially relates to a high-pressure die, including terrace die and die, form molding cavity behind terrace die and the die compound die, the terrace die includes the terrace die contact surface and locates terrace die contact surface middle part and be used for slip casting's terrace die shaping face, and the die includes the die contact surface and locates die contact surface middle part and be used for slip casting's die shaping face, and terrace die contact surface and die contact surface are made by quartz material, the utility model discloses with the mould to the mouth position with quartz material substitution, because of the good water permeability of quartz material, higher hydroscopicity, and quartz material surface accessible is hit the wind and is carried out the drying, consequently handles the mouth department with quartz face of mould, can effectively improve the product and the rough living and the thick liquid problem of running of the mouth that appears in process of production, effectively practice thrift raw materials, improved enterprise's benefit.

Description

High-pressure die

Technical Field

The utility model relates to a mould equipment field especially relates to a high-pressure mould.

Background

In the prior art, ceramic products are produced and manufactured. The high-pressure forming process has been accepted by more and more ceramic enterprises due to the advantages of high daily average productivity of a single set of die, high automation degree and high utilization rate of personnel and sites, and the high-pressure die comprises a convex fan die and a concave fan die. In the production process, the convex fan die and the concave fan die are firstly closed and held tightly, then grouting is carried out in the dies until slurry is formed in the dies for a certain time, and then the dies are opened. At present, the multi-purpose epoxy resin of high pressure mould does the face of pressing of keeping to the mouth of mould, behind the compound die of keeping to the mouth, because the water-insoluble characteristic of epoxy, moisture in the mould extrudees the mould during pressurization slip casting and remains to the mouth department, when leading to high notes, the product body appears low in density in the mould to the mouth department, the water content is big, mould extremely easily appears running thick liquid problem to the mouth department, easily appear when dry and fire the product simultaneously and the crack of later stage to the mouth, influence pleasing to the eye degree and the product yields of product, also reduced highly compressed production efficiency when causing the waste for production.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a can effectively solve the product and run the thick liquid and to the high-pressure mould of the rough living problem of mouth.

The utility model discloses a realize through following technical scheme:

a high pressure die, comprising: the male die and the female die form a forming cavity after being matched,

the male die comprises a male die contact surface and a male die forming surface which is arranged in the middle of the male die contact surface and used for slip casting,

the female die comprises a female die contact surface and a female die forming surface which is arranged in the middle of the female die contact surface and used for slip casting,

the male die contact surface and the female die contact surface are both made of quartz materials.

Preferably, the male die forming surface and the female die forming surface are both made of quartz and resin materials through mixing.

Preferably, the female die and the male die are respectively provided with an air blowing hole.

Preferably, a positioning bulge is arranged on the contact surface of the male die, and a corresponding positioning groove is arranged on the contact surface of the female die.

The utility model has the advantages that:

replace the mould to mouthful position with the quartz material, because of the good water permeability of quartz material, higher hydroscopicity, and quartz material surface accessible is hit the wind and is carried out the drying, consequently handles the mouth department with the quartz face of mould, can effectively improve the product and the production raw materials are effectively practiced thrift to the rough living and the thick liquid problem of running of mouthful that appears in process of production, have improved the performance of enterprises.

Drawings

Fig. 1 is a schematic sectional structure diagram of the present invention.

Fig. 2 is a schematic structural view of the male mold.

Fig. 3 is a schematic structural view of the female mold.

In the figure: 1. the device comprises a male die, a female die, 3 a forming cavity, 4 a female die contact surface, 5 a female die forming surface, 6 a male die contact surface, 7 a male die forming surface, 8 a positioning groove and 9 a positioning bulge.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a: the male die 1 and the female die 2 are matched to form a molding cavity 3, slurry is injected into the molding cavity for filling, a semi-finished product is formed after molding,

the male die comprises a male die contact surface 6 and a male die forming surface 7 which is arranged in the middle of the male die contact surface and used for slip casting,

the female die comprises a female die contact surface 4 and a female die forming surface 5 which is arranged in the middle of the female die contact surface and used for slip casting,

the male die contact surface and the female die contact surface are in close contact, the male die contact surface and the female die contact surface are made of quartz materials, the water permeability of a quartz layer is good, the water absorption is high, the surface of the quartz material can be dried by blowing air through the air blowing holes formed in the female die and the male die, the drying effect is better after the product is demoulded, the hardness of a semi-finished product is high, and the later deformation is easy to control.

Preferably, the male die molding surface and the female die molding surface are both made of quartz and a resin material through mixing, the resin material used in the embodiment is a commercially available 350 resin, the molding is simple, the preparation is convenient, and the 350 resin and the quartz are mixed and then are fixed for molding.

Preferably, a positioning protrusion 9 is arranged on the contact surface of the male die, a corresponding positioning groove 8 is arranged on the contact surface of the female die, and when the die is closed, the positioning protrusion is inserted into the positioning groove, so that the male die and the female die can be quickly positioned and closed, and the male die and the female die are prevented from being displaced in the die closing process to influence the product quality.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
