Abstract
The present invention relates to micro air bag making process and belongs to the field of manufacturing technology. After the upper mold and the lower mold are closed, one cavity and one air needle passage communicated to the cavity are formed inside the mold combination. The micro air bag making process includes the following steps: separating the upper mold and the lower mold, setting the air needle into the mold cavity, feeding hot silica gel into the cavity with some feeder and piercing the air needle into hot silica gel; closing the upper mold and the lower mold, withdrawing the feeder, inflating through the air needle into the silica gel, and withdrawing the air needle; and final cooling the silica gel to form micro air bag. The present invention can control the sizes of the micro air bag initially.
Description
Technical field
The present invention relates to a kind of processing method of little air bag, belong to the manufacturing technology field.
Background technology
Along with IT industry, the develop rapidly of precision instrumentation industry, small-sized, accurate, portable utensil, device are the trend that increases year by year., be accompanied by a large amount of use of this series products, it is subjected to the accidental shock malicious event also with regard to a large amount of generations.Particularly for the multiple track hard disk of mobile memory, be hit slightly, data just can't be read and recover, and the price of the value of the mobile memory after using will be higher than with the article new product far away the time.For this reason, IT product, precision instrumentation product, particularly the portable hard drive series products should have the buffering antishock device, the destroyed accident of being brought in the hope of the minimizing accidental shock of maximum possible of data.The anti-seismic technology of antidetonation hard disk is adopted built-in little airbag structure usually at present, and little air bag is the Primary Component of this technology.For example when mobile hard disc box when to adopt 54 diameters be little air bag about 30mm, will take passive buffer protection on 6 faces to the portable hard drive core, this portable hard drive can bear 3 meters high dropping shocks.
Usually adopt air tube that the method for hot silica gel inflation is processed little air bag at present, this processing method relies on operating personnel's experience to guarantee the shape and the size of little air bag usually, physical dimension and shape to little air bag do not have effective control method, so the percent defective height.
Summary of the invention
The objective of the invention is to overcome the defective that above-mentioned dependence manual method is processed little air bag, a kind of method of utilizing the little air bag of Mould Machining is provided.This method can tentatively realize the control to little bonnet geometry size and dimension, the rate of reducing the number of rejects and seconds effectively.
To achieve these goals, the present invention has taked following technical scheme.Patrix 5 and counterdie 7 that this method utilization is symmetrical are realized, wherein, the inside same position of patrix 5 and counterdie 7 all has a cavity, end at cavity is connected with air tube passage 2, when patrix 5 and counterdie 7 closures, in an inner complete cavity 1 and an air tube passage 2 that is communicated with cavity 1, air tube passage 2 and the external communications of forming of whole die body.
Utilize said apparatus to make little air bag, its processing method is as follows:
1) with patrix 5 and counterdie 7 separately, air tube 3 is stretched into the cavity 1 that patrix 5 and counterdie 7 are formed from air tube passage 2, utilize feeding pincers 6 that hot silica gel 4 is sent into this cavity 1 from opposite side again, and simultaneously air tube 3 is thrust in the hot silica gel 4.
2) closed patrix 5 and counterdie 7 withdraw from feeding pincers 6 simultaneously from mold.
3) by inflation in the air tube 3 thermotropism silica gel 4, make hot silica gel 4 inner gassies after, air tube 3 is withdrawed from mold in circular channel 2.
4) after being cooled off naturally, hot silica gel 4 can form little air bag.
Described patrix 5 adapts with shape, the shape and the size big or small and little air bag of the cavity that counterdie 7 closed backs form, and this spherical hollow space is used for the control to the shape and the physical dimension of little air bag.
The cavity that described patrix 5 and counterdie 7 closed backs are formed be spherical, and the cross section of coupled logical air tube passage 2 is a circle.
Patrix 5 and counterdie 7 have been used in this technological process, when patrix 5 and counterdie 7 closures, the complete spherical hollow space of the inner formation of die body, this cavity can be realized preliminary control to the shape and the physical dimension of little air bag in the forming process of little air bag, this processing technology can realize the preliminary control to little bonnet geometry size, the rate of reducing the number of rejects and seconds effectively.

Among the figure: 1, spherical hollow space 2, air tube passage 3, air tube, 4, hot silica gel, 5, patrix, 6, the feeding pincers, 7, counterdie.
The specific embodiment
The specific embodiment of the present invention is referring to Fig. 1~2.Present embodiment mainly includes air tube 3, hot silica gel 4, patrix 5, feeding pincers 6, counterdie 7.Processing process comprises feeding process and inflation process.
Patrix 5 and counterdie 7 that the present embodiment utilization is symmetrical are realized, when patrix 5 and counterdie 7 closures, in an inner cavity 1 and an air tube passage 2 that is communicated with cavity, air tube passage 2 and the external communications of forming of whole die body.
Utilize said apparatus to make little air bag, its processing method is as follows:
1) with patrix 5 and counterdie 7 separately, air tube 3 is stretched into the spherical hollow space 1 that patrix 5 and counterdie 7 are formed from the air tube passage, utilize feeding pincers 6 that hot silica gel 4 is sent into this cavity from opposite side again, and air tube 3 is thrust in the hot silica gel 4 simultaneously;
2) closed patrix 5 and counterdie 7 withdraw from feeding pincers 6 simultaneously from mold;
3) by inflation in the air tube 3 thermotropism silica gel 4, make hot silica gel 4 inner gassies after, air tube 3 is withdrawed from mold in circular channel 2;
4) will can form little air bag after hot silica gel 4 coolings.
The shape of shape, size and little air bag of the cavity that patrix 5 and counterdie 7 closed backs form, measure-alike.This spherical hollow space is used for the moulding of little air bag and the control of physical dimension.
Patrix 5, counterdie 7 can be cast processing with mould steel in the present embodiment, and air tube 3, feeding pincers 6 are commercially available standard component, and hot silica gel 4 can be made by commercially available silica gel heating.The manufacturing of little air bag is pressed processing process and is got final product.
