A kind of hollow pin mould
This utility model relates to suppository pharmaceutical production technical field, is specifically related to a kind of hollow pin mould.
The suppository mould that existing in the market test is used or small-scale production is used, the traditional moulds of forming by upper die and lower die mostly, can only produce the suppository product that medicine and substrate can finely mix, the scope of application is very limited, and can't solve suppository product easily oxidation in use, short problem of medicine shelf-life, traditional suppository product can't solve the difficult problem of concentrated administration, timing administration simultaneously.
The utility model content
In order to solve the problem that prior art exists, it is a kind of applicable to the immiscible suppository production of medicine and substrate, the hollow pin mould of medicine good airproof performance that this utility model provides.
The technical solution adopted in the utility model is:
A kind of hollow pin mould comprises upper die and lower die, and described patrix cooperates with counterdie, described patrix and counterdie are provided with the molding hole, also comprise the hollow molding mould, described hollow molding mould and patrix are supporting, and corresponding molding hole, described hollow molding mould bottom is provided with shaping column.
Wherein, described shaping column is arranged on the axis in molding hole.
Wherein, the diameter of the cross section of described shaping column is less than the diameter 1～3mm of the big cross section of molding Kongzui.
Wherein, described molding hole is oval, ellipse or bullet shaped.
The beneficial effects of the utility model are:
1, solved suppository production process Chinese medicine composition and suppository base when immiscible, technological problems that can't molding has satisfied the dosage form demand of suppository;
2, after use mould of the present utility model has been prepared hollow pin, in hollow pin, inject medicine, pour into substrate again and seal, thus,, thereby can prolong keeping life because the medicine quilt is effective and air is isolated;
3, the suppository product of use mould production of the present utility model can satisfy the demand of concentrated administration, timing administration;
4, of the present utility model rational in infrastructure, easy to operate, small investment, economical and practical.
Description of drawings
Accompanying drawing is the structural representation of a kind of hollow pin mould of this utility model.
Description of reference numerals is as follows:
The 1-patrix, 2-molding hole, 3-counterdie, 4-hollow molding mould, 5-shaping column.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is done detailed description.
Referring to Fig. 1, a kind of hollow pin mould, comprise patrix 1 and counterdie 3, described patrix 1 cooperates with counterdie 3, described patrix 1 is provided with molding hole 2 with counterdie 3, also comprise hollow molding mould 4, described hollow molding mould 4 is supporting with patrix 1, and corresponding molding hole, described hollow molding mould 4 bottoms 2 is provided with shaping column 5.
Wherein, described shaping column 5 is arranged on the axis in molding hole 2.
Wherein, the diameter of the cross section of described shaping column 5 is less than the diameter 1～3mm of 2 maximum cross sections, molding hole.
Wherein, described molding hole 2 is oval, also can be ellipse or bullet shaped.
Duty: with patrix 1 and counterdie 3 combinations, pour into an amount of suppository base (volume of substrate deducts the volume of shaping column 5 less than suppository simple grain volume) in molding hole 2, then hollow molding mould 4 and patrix 1 are cooperated, after treating the molding of substrate cooled and solidified, take off hollow molding mould 4, form hollow pin this moment.
Should be noted that at last; above content is only in order to the explanation the technical solution of the utility model; but not to the restriction of this utility model protection domain; although this specific embodiment part has been done to explain to this utility model; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
