Description

Powder dish injection mould

Technical field

The utility model relates to a kind of powder dish injection mould.

Background technology

Powder box by general cosmetics, after the moulding of portion's general layout design within it, install for the powder dish that has filled cosmetic powder (containing solvent), and known powder dish fills the powder processing procedure, be after the number disk body is inserted powder one by one, need earlier via the striking off back and forth of number repeatedly, strickling process, just again the mat impact style with mould punch forming one by one, yet this processing procedure obviously exists following shortcoming:

1. the miscellaneous inconvenience of processing procedure lacks uniformity, mass production rapidly;

2. after disk body is inserted powder,, cause operating environment pollution, waste raw material and do not meet hygienic requirements through the powder that strikes off, wipes off the back back and forth of number repeatedly;

3. disk body is inserted the core of powder, after wipeing off, easily causes surperficial discontinuous shape, again through punching press, very easily improves the fraction defective of finished product, if the mobile gastrointestinal disease patient of powder, this non-uniform phenomenon is then more remarkable;

4. mould is in punching press powder compacting process, and air and the contained air of powder in the mould can't be discharged fully, make the interior powder of disk body unsturdy, produces flaw such as slight crack, lacks material, outward appearance tarnish etc.;

5. mould easily causes powder to infiltrate crack between the mould in punching course, causes the mould friction, influences the outward appearance integrality;

6. contained solvent in the powder under nature, is difficult for dry, mass production rapidly, thus need again drying equipment can finish, the apprentice increases cost of manufacture.

The utility model content

The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, a kind of powder dish injection mould is provided, makes powder dish processing procedure facility, quick suction air and solvent, to realize that the powder dish is sturdy, rapid draing, attractive in appearance indefectible, reach the purpose that promotes production capacity efficient effectively.

For achieving the above object, the utility model has designed a kind of powder dish injection mould, includes involutory upper die and lower die mutually; Should go up module system and can be shifted up and down by the driving of an oil hydraulic cylinder, this patrix has connected several powder injecting pumps and a vavuum pump, and this counterdie below cover has closed the number sucker that is connected to vavuum pump, and this counterdie top is equipped with one and carries cloth and a blotting paper; This patrix, the involutory surface of itself and counterdie is provided with number can be for desiring to fill in powder dish groove, what be provided with in this dish groove that an aspirating unit and that is connected to vavuum pump is connected to powder injecting pump leads the notes road, and this aspirating unit can be involutory in the bottom surface of disk body, and it is involutory that this leads through hole of annotating road and disk body; This counterdie, it is provided with number and the corresponding forming tank of last mould groove with the involutory surface of patrix, and this forming tank is laid with the number that runs through and bleeds, and this number sucker cover that the lower end is connected to vavuum pump of bleeding closes fixing.

The forming tank external diameter of this counterdie is identical with the disk body internal diameter.

The aperture that the set number of the forming tank of this counterdie is bled is preferably 0.8mm.

The forming tank inner peripheral of this counterdie can be made as difformity and decorative pattern.

Powder dish injection mould provided by the utility model, this patrix is subjected to the driving of an oil hydraulic cylinder, can be shifted up and down, the aspirating unit of this patrix is connected to a vavuum pump, the number of this patrix is led the notes road, and each has connected a powder injecting pump respectively, the number of the laying lower end of bleeding is closed by a sucker cover that is connected to vavuum pump in the number forming tank of this counterdie, and above counting forming tank, lay soft thin conveying cloth, blotting paper, by above-mentioned member, be inverted in the dish groove of patrix with disk body, aspirating unit by this dish groove adsorbs the disk body bottom surface automatically, patrix is subjected to the driving decline displacement of oil hydraulic cylinder, the dish groove of patrix closes mould together with the forming tank driving fit of disk body and counterdie, lead the notes road through powder injecting pump good general powder input patrix, do to push to flow in disk body and the counterdie forming tank to be moulded the powder dish according to the through hole of disk body, the mat vavuum pump of bleeding of following again mold forming groove, the powerful suction of sucker is than the aspirating unit suction greater than patrix, cooperating oil hydraulic cylinder to rise is shifted, make powder disk detachment patrix and keep somewhere in the number of counterdie top and carry cloth, on the blotting paper, and be positioned at forming tank, continue according to sucker through vavuum pump, bleed to force and bleed, make interior powder residual air of powder dish and solvent discharged by suction, reach sturdy, quick-drying purpose.

So close mould by the mutual driving fit of upper and lower mould, the powder dish is with the moulding of injection moulding mode, be moulded at extremely short process time, reach the number disk bodies to be led by the number of patrix respectively and annotate the road and fill in the powder of identical or different color simultaneously and once finish, and the number disk body can be filled in the powder dish outward appearance that powder presents difference by difformity, the decorative pattern forming tank of counterdie respectively with the number disk body, mean the epoch-making property rationalization of the manufacture process that can realize the powder dish, for the cosmetics powder box manufacturing industry that traditional-handwork carries out has been opened an automation road that converts to by machinery.
