Description

A kind of casting mold for ceramic green body

technical field

The utility model relates to the manufacturing industry of sanitary ceramic sanitary ware, in particular to a casting mold for a ceramic green body.

Background technique

In the existing ceramic industry, the vertical casting mold is the most widely used, but the existing vertical casting mold is made by traditional technology, which takes too long, resulting in low production efficiency. In order to improve the green body forming efficiency, the existing The vertical casting mold is introduced into the high-pressure process for production. Since the discharge process in the high-pressure forming process is only 60-100 seconds, the mud discharge step needs to be completed in a shorter time, otherwise local mud accumulation is easy to occur, especially in the product. One side of the wall, because it is a plane, is the most likely to cause endless mud discharge, which eventually leads to local stress and rupture of the sintered product; although the existing process uses external equipment to dump the entire mold frame However, due to the tilting of the overall mold frame and the change of the mold clamping direction, it is easy to cause misalignment and difficult to locate mold loading defects during mold assembly and production. Therefore, the existing casting mold still needs further improvement.

Utility model content

The purpose of the utility model is to solve the existing problems, and to provide a casting mold for ceramic blanks, which has a simple structure, reasonable design and is easy to realize. Insufficient pulp produces accumulation and other phenomena;

In order to achieve the above object, the utility model adopts the following technical solutions:

A casting mold for a ceramic body, which includes a first mold and a second mold, the first and second molds are arranged oppositely and the two cooperate to form a cavity for molding the green body; the cavity of the first mold has An inner surface arranged in a plane, the inner surface is composed of a long side and two sides perpendicular to the long side, the outer surface of the product corresponding to the inner surface is used for the product to be placed against the wall; the first mold A slurry port is provided; the inner surface in the cavity of the first mold is arranged horizontally, and the cavity of the first mold is arranged obliquely along the long side and the side of the horizontally arranged inner surface, so that the slurry port is located at The lowest position of the cavity.

Further, the cavity of the first mold is inclined at 2-5° along the long side and side side of the horizontal inner surface.

Compared with the prior art, the technical solution described in the utility model has the beneficial effects of:

(1) The ceramic blank casting mold provided by the utility model has simple structure, reasonable design and easy realization. By setting the mold cavity at an inclination, the slurry opening can be set at the lowest point in the cavity without external assistance. The equipment can realize the effect of rapid pulp discharge, and avoid the phenomenon of accumulation caused by insufficient pulp discharge;

(2) The inclination angle of the mold cavity of the utility model is 2.5-5°, within this angle range, the effect of fast pulp discharge can be effectively achieved, and smooth demoulding can be ensured.

detailed description

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer and clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 and 2, a casting mold for a ceramic body includes a first mold 1 and a second mold 2, the first and second molds 1 and 2 are arranged oppositely and the two cooperate to form a ceramic body for molding The cavity 3 of the first mold 1 has an inner surface 10 arranged on a plane in the cavity 3, and the inner surface 10 is composed of a long side 101 and two sides 102, 103 perpendicular to the long side 101, so The outer surface of the product formed corresponding to the inner surface 10 is used for setting the product against the wall; the first mold 1 is provided with a slurry port 11; the inner surface 10 in the cavity 3 of the first mold 1 is horizontally arranged, and The cavity 3 of the first mold 1 is arranged obliquely along the long side 101 and the side of the inner surface 10 arranged horizontally, and the cavity 3 of the first mold 1 is arranged along the long side 101 and the side of the inner surface 10 arranged horizontally Inclined by 2-5°, so that the slurry mouth 11 is located at the lowest position of the cavity 3 .

Specific embodiments, as shown in Figures 1 to 5, a casting mold for a ceramic body according to the utility model mainly includes a first mold 1 and a second mold 2;

During actual production, as shown in Figure 3, at first make master mold 4, utilize master mold 4 to make first, second mold 1,2; Before making first, second mold 1,2, earlier master mold 4 Placed on the horizontal platform, the master mold 4 is formed with an auxiliary plane 40 corresponding to the product against the wall (the auxiliary plane 40 is the inner surface of the first mold 1 cavity 3 that is horizontally arranged when the first mold 1 is subsequently produced. 10 plane), subsequently, a pipe fitting 5 is installed at the corner of the auxiliary plane 40 and one side of the master mold 4, and then the diagonally opposite corner of the pipe fitting 5 is installed at the bottom of the master mold 4 by 2.5-5° , and then the part of this cushion is filled up with plaster, at this time the master mold 4 is inclined at a certain angle as a whole, (as shown in 4) followed by surrounding the master mold 4 with a shroud 6 to form an accommodating space 7, the Epoxy resin is poured into the accommodating space 7 surrounded by the coaming plate 6, and the first mold 1 is formed after the epoxy resin is solidified and formed.
