Abstract

The utility model discloses a master mould. The master mould comprises a mould body, a cavity and a stamping mould air nozzle, wherein the mould body and the cavity are integrally formed, the cavity is arranged inside the mould body, the end surface of the mould body is provided with a mould outlet penetrating through the cavity, and the stamping mould air nozzle is a pipeline penetrating from the outer wall of the mould body to the cavity. Due to the fact that the master mould is integrally formed, the problems that when a master mould of a split structure is adopted, a production mould is deformed and leaks slurry are resolved.

Description

A kind of master mold

Technical field

The utility model relates to the tool of production, particularly relates to a kind of production mould master mold.

Background technology

The master mold of ceramic utensil (comprising cleaners and polishes) production use does not directly form ceramic body, but the production mould slip casting producing through it forms base substrate, so the problem that master mold exists generally just can embody after the use procedure of production mould and base substrate burn till.Production mould is that gypsum material is made mostly, and its manufacture process is: clear up and combine master mold-> calcium plaster and inject tentatively solidify-> of master mold-> heating final set-> partition master mold-> and take out production mould-> and repair, mend surface-> and combine complete production mould.Please refer to Fig. 1 to Fig. 3, because gypsum is in the process of setting expansion of can generating heat, so in order to make production mould convenient to remove from master mold, just master mold is designed to the mould of detachable and assembling A, B, C, D, E, F.The production mould that master mold detachable and assembling is produced has following shortcoming:

1. during due to assembling, the assembling face of master mold is alignment not, easily cause porcelain base thickness and the pipe shape of the ceramic utensil of production mould institute moulding to change, and varied in thickness very easily causes ceramic utensil cracking and distortion, pipeline changes the function that has a strong impact on ceramic utensil;

2. just because of gypsum, in process of setting, can expand; this just makes master mold detachable and assembling can cause production mould to deform in forming process; this can cause production mould spillage, thereby causes occurring on the porcelain base of ceramic utensil the seam mark of Density inhomogeneity.

Utility model content

In view of this, be necessary to provide a kind of master mold that can address the above problem.

The technical scheme that the utility model provides is: a kind of master mold, comprise mold and die cavity, also comprise punch die valve, described mold and die cavity are formed in one and form, described die cavity is arranged on mold inside, described mold end face is provided with the die orifice that goes out that is through to die cavity, and the described punch die valve described mold outer wall of serving as reasons is through to the pipeline of die cavity.

Compared with prior art, the mold of the master mold that the utility model provides and die cavity adopt and are made of one piece, and by the outer wall setting at mold, be through to the punch die valve of die cavity, by gases at high pressure being filled with to punch die valve, thereby production mould is taken out from master mold.Because mold and the die cavity of master mold is made of one piece, thereby the production mould distortion that the master mold of the detachable structure of available technology adopting causes, the unfavorable condition that spillage appears in production mould have been avoided.

The specific embodiment

Now the utility model is described in further detail with the specific embodiment by reference to the accompanying drawings.

A kind of master mold that the utility model the first embodiment provides comprises a mold 1, a die cavity 2 and a punch die valve 3.Described die cavity 2 is arranged on mold 1 inside, and described punch die valve 3 is arranged on the bottom of this mold 1, and described die cavity 2 is for the production mould of forming ceramic utensil.

Please refer to Fig. 4 and Fig. 5, described mold 1 is made for resin material.Described die cavity 2 and described mold 1 are formed in one and form.Described mold 1 end face be provided be through to described die cavity 2 go out die orifice 11, described in go out die orifice 11 internal diameters and be greater than described die cavity 2 maximum inner diameters.

The center of gravity line of the production mould of 2 moulding of the corresponding described die cavity of described punch die valve 3 is arranged on described mold 1 bottom.Described punch die valve 3 described mold 1 outer wall of serving as reasons is through to the pipeline of die cavity 2.

The using method of this master mold is,

Step 1: calcium plaster is poured in the die cavity 2 of master mold.

Step 2: in gypsum initial set but add gases at high pressure that production mould is extruded from die cavity 2 from punch die valve 3 while also not expanding.

In sum, the mold 1 of the master mold that the utility model provides and die cavity 2 adopt and are made of one piece, and by the outer wall setting at mold 1, be through to the punch die valve 3 of die cavity 2, its using method is not for when the gypsum initial set of production mould but when expand, by gases at high pressure being filled with to punch die valve 3, thereby production mould is taken out from master mold.Because mold 1 and the die cavity 2 of master mold is made of one piece, thereby the production mould distortion that the master mold of available technology adopting fraction block structure causes, the unfavorable condition that spillage appears in production mould have been avoided.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.

Claims

1. a master mold, comprise mold and die cavity, it is characterized in that: also comprise punch die valve, described mold and die cavity are formed in one and form, described die cavity is arranged on mold inside, described mold end face is provided with the die orifice that goes out that is through to die cavity, and the described punch die valve described mold outer wall of serving as reasons is through to the pipeline of die cavity.

2. master mold according to claim 1, is characterized in that: the center of gravity line of the corresponding described die cavity of described punch die valve institute shaped article is arranged on described mold bottom.
