Abstract
The invention relates to an application method of a stripping-convenient mold. The mold comprises a lower mold and an upper mold. The lower mold is provided with an opening, and a groove is formed at the bottom center of the opening of the lower mold. A spring positioning rod is arranged at the center of the groove vertically, the upper end of the spring positioning rod is flush with the bottom of the opening of the lower mold, a spring is sleeved on the spring positioning rod, an ejector plate is arranged at the upper end of the spring, and the shape of the ejector plate is matched with that of the opening. The application method includes steps of opening the upper mold and positioning the lower mold, coating releasing liquid on four walls of the opening of the lower mold, feeding to-be-sintered powder into the lower mold and compacting the powder so that the ejector plate overcomes elasticity of the spring to be pressed and to be limited by a step at the bottom of the opening, opening the upper mold after sintering and shaping of the powder, beating side walls of the lower mold by a hammer to drive the spring to lift the ejector plate so as to eject a product from the lower mold, and thereby completing the stripping process. The mold is convenient to strip and high in production efficiency, and the yield can be guaranteed.
Description
Technical field
The present invention relates to a kind of mould using method, relate in particular to a kind of conveniently stripped mold use method.
Background technology
How carrying out the demoulding is the inevitable problem of die industry.Existing stripping means has: Pneumatic demould, the elastic force demoulding etc.Existing mould by the elastic force demoulding often arranges an elastic force mould emptier at mould inside, and after formed product, the operation mould emptier makes its action, and ejecting product is finished the demoulding.
This mould inside structure is comparatively complicated, make, maintenance cost is higher, and each demoulding all needs the elastic force mould emptier is resetted after complete, in case operate miss will cause product rejection.As seen this elastic force mould emptier has reduced production efficiency, has improved percent defective, industrially extensive use.
Summary of the invention
The object of the invention is to overcome the defective of above-mentioned prior art, a kind of conveniently stripped mould is provided, it is simple in structure, and is cheap for manufacturing cost, and is convenient in demoulding, and can guarantee yield rate.
Above-mentioned purpose is realized by following technical proposals: conveniently stripped mold use method provided by the invention, it is characterized in that: described mould comprises bed die, mold, described bed die is with uncovered, the bottom center position that bed die is uncovered offers groove, central authorities are vertical in this groove is provided with the spring backstay, the bottom that the upper end of spring backstay and bed die are uncovered flushes, cover has spring on the spring backstay, the upper end of described spring is provided with top board, the shape of described top board and uncovered being complementary; Using method comprises the steps:
The first step, open mold and will locate bed die;
Second step, touching down the uncovered wall of tool spraying liquid parting;
The 3rd goes on foot, down touches input powder to be sintered and compacting in the tool, and the elastic force that makes top board overcome spring is pressed down and is spacing by the step of open bottom institute;
After the 4th step, the powder sintering typing, open mold, the bed die sidewall that strikes with a hammer makes spring jacking top board, and product is ejected in bed die, finishes the demoulding.
As seen, the present invention is simple to operate, is convenient in demoulding, and production efficiency is high, and can guarantee yield rate.
Description of drawings
Fig. 1 is the conveniently stripped mould structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the mould that the embodiment of the invention is conveniently stripped, comprise bed die 2, mold 1, counterdie 2 tools are with uncovered 5, and the bottom center position of bed die uncovered 5 offers groove 3, and groove 3 central authorities are vertical is provided with spring backstay 7, the upper end of spring backstay 7 flushes with the bottom of bed die uncovered 5, cover has spring 4 on the spring backstay 7, and the upper end of spring 4 is provided with top board 6, and the shape of top board 6 and uncovered 5 is complementary; Using method comprises the steps:
The first step, open mold and will locate bed die;
Second step, touching down the uncovered wall of tool spraying liquid parting;
The 3rd goes on foot, down touches input powder to be sintered and compacting in the tool, and the elastic force that makes top board overcome spring is pressed down and is spacing by the step of open bottom institute;
After the 4th step, the powder sintering typing, open mold, the bed die sidewall that strikes with a hammer makes spring jacking top board, and product is ejected in bed die, finishes the demoulding.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
