Abstract

The utility model discloses a low pressure fast drainage plaster mold used for green body molding before ceramic firing. The low pressure fast drainage plaster mold comprises an inner cavity and a mold body, and is characterized in that a layer of pipe network is uniformly distributed in the mold body apart from the inner wall of the mold body of 2.9cm-3.1cm, the pipe network is composed of transverse pipes and vertical pipes in an interweaving mode, the transverse pipe distance is 6cm, the vertical pipe distance is 6cm, and internals of the transverse pipes are mutually communicated with internals of the vertical pipes; the pipe network is just provided with a port which extends to the external of the mold body and is connected to an air compressor through a compression air pipe; and needle holes are densely distributed in pipe walls of the transverse pipes and the vertical pipes. The low pressure fast drainage plaster mold not only can remarkably improve the yield and the quality of green bodies, but also can reach mold drying requirements without the need of high temperature inside a workshop in summer, and can obviously improve the work environment.

Description

The low-pressure quick drainage gypsum mold

Technical field

The utility model relates to a kind of mould, is used for the front blank forming of ceramic sintering, specifically a kind of low-pressure quick drainage gypsum mold.

Background technology

Before ceramic sintering, need first blank to be made the base substrate of given shape size in mould, base substrate is fired through polishing, the laggard stove of glaze spraying.

Because existing mold is generally made by gypsum, carry large quantity of moisture during again because of the casting of blank slurries, so in the cast green body process, gypsum mold can absorb and ooze out large quantity of moisture, to help the moulding of base substrate midge.But, if use the same gypsum mold base substrate of again casting, must wait for that mould is dry, otherwise gypsum mold is out of shape easily, thereby have influence on the yield rate of base substrate, yet, the time of mould drying needs 12-20 general according to factors such as environment temperature, humidity hour, therefore, mainly there is following problem in prior art: one, mould is long drying time, and workman every day can only cast green body 1 time, and output can not get promoting always; Two, due to complete manually-operated, different subjective judgements is arranged unavoidably in die molding process, cause the green body quality quality to differ; Three, mould is reused 90 times just to be needed to destroy afterwards, has increased production cost; Four, dry for making mould, need to keep high temperature in the workshop, especially will make being in for a long time under hot environment of workman in summer, be unfavorable for healthy.

The utility model content

The utility model provides a kind of low-pressure quick drainage gypsum mold for addressing the above problem.The utility model not only can significantly improve the base substrate Yield and quality, and does not need summer high temperature can reach the dry requirement of mould in the workshop, can obviously improve working environment.

For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:

A kind of low-pressure quick drainage gypsum mold comprises inner chamber and die body, it is characterized in that: the die body inside apart from die body inwall 2.9cm-3.1cm place is evenly equipped with one deck pipe network, pipe network is interweaved by transverse tube and vertical tube and forms, transverse pipe is apart from being 6cm, and vertical duct is apart from being 6cm, and transverse tube and vertical tube internal mutual are connected; Pipe network only has a port, and port extends to the die body outside and is connected on air compressor by compression gas pipe.

Be densely covered with pin hole on the tube wall of aforementioned transverse tube and vertical tube, the gas of being convenient in netted flexible pipe is discharged.

Air door and pressure regulator valve are arranged on aforementioned compression gas pipe, be convenient to regulate compressed air and be in low-pressure state.

Pipe network makes the die body between pipe network and inner chamber that enough thickness be arranged apart from die body inwall 2.9cm-3.1cm, ensures that the not compressed gas of die body washes out, and can make again low-pressure gas discharge fast die body, ensures drainage speed; Transverse pipe distance, vertical duct ensure die body in the situation that absorption moisture can bear the pressure from low-pressure gas apart from being 6cm.

Adopt technique scheme, compressed air enters in die body by pin hole on pipe network, the timely pressure of blank slurries moisture that die body absorbs can be gone out, make die body moisture be in all the time undersaturated condition, be conducive to the die body suction, and, can also increase the pressure of base substrate both sides, accelerate the formation of base substrate thickness, in addition, continue to carry the low pressure gas physical efficiency that moisture residual in die body is discharged after the taking-up base substrate, accelerate the drying of mould, especially when summer, ambient air temperature is not had special requirement, do not need to improve specially the workshop temperature.

The utility model is in blank forming demoulding slip casting again after 60 minutes, reusable 9 times of every day, in the comparison prior art, can only use mould every day 1 time, can significantly improve base substrate output, and the mould access times are 160 times, than improving 1 times nearly 90 service lifes of the prior art, reduced production cost.In addition, because no longer need to heat in the workshop summer, obviously improved working environment.
