Abstract
The invention discloses a production process for a one-piece socket. A raised riveting pillar is injection-molded on a base when the base is formed; a shell is punched with a riveting hole matched with the riveting pillar on the base after the shell is formed; after the shell and the base are assembled, the riveting pillar is heated to soften the part, passing through the riveting hole, of the riveting pillar; the softened riveting pillar is riveted to the riveting hole by a metal riveting head; and the base and the shell are riveted together after the riveting pillar is cooled. According to the invention, by changing the mode of connection between the shell and the base, the shell is connected to the base more firmly and reliably, the shell can be prevented from loosening and falling off, and the production efficiency is improved by a hot riveting process.
Description
Technical field
The present invention relates to electrical connector manufacturing technology field, particularly a kind of production technology of disjunctor socket.
Background technology
Socket is a kind of common electrical connector, generally include base and shell two parts, base and shell are all made by insulating material, jacket is above base and leave jack, conductor copper sheet is provided with in jack, base is provided with heart yearn, is inserted in jack by appliance plug and contacts with copper sheet, electrical equipment can be connected into electrical network.
Socket disclosed in prior art in process of production, shell and base are separate machined, during assembling, shell and base rely on copper sheet and heart yearn weld and link together, need in process of production to weld copper sheet and heart yearn one by one, the method speed of production is slow, in use to have grown solder joint easily aging the time for product, and then cause loosening of product, and shell can be caused time serious to come off.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of production technology of disjunctor socket, with reach make shell more solid and reliable be connected on base, prevent the object of shell loose or dislocation.
For achieving the above object, technical scheme of the present invention is as follows:
A production technology for disjunctor socket, is characterized in that, comprises the following steps:
A, base patrix and base counterdie matched moulds, by the plastic raw materials after injection molding machine injection fusing, plastic raw materials enters cavity forming through charging runner, cooling body on base patrix makes base cooling and shaping, finally utilize the liftout attachment of base counterdie to eject base, described base is injected with protruding riveting post.
B, plastic raw materials melted and is injection molded into shell, after described shell demoulding cooling, stamping out the rivet hole matched with described riveting post thereon.
C, the shell obtained by step b are assembled on the obtained base of step a, make described riveting post through described rivet hole.
D, add rivet hot post make its part of passing described rivet hole soften.
Softening riveting post is pressed to rivet hole by e, use metal die, base and shell is riveted together after the cooling of riveting post.
Preferably, after in step a, die cavity fills up by plastic raw materials, screw in injection molding machine continues to apply pressure in die cavity until die cavity internal pressure rises to 120-140 MPa and keeps 6-7 second.For by the plastic melt compacting in die cavity, increase the density of plastic melt in die cavity, the shrinkage phenomenon of plastics during to compensate cooling and shaping.
Preferably, in step e, base and shell are flush riveting, and flush riveting makes the junction of base and shell more smooth.
Pass through technique scheme, the production technology of a kind of disjunctor socket provided by the invention is by changing the connected mode of shell and base, make shell more solid and reliable be connected on base, shell loose or dislocation can be prevented, use hot riveting technique also to make production efficiency be improved simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the process chart of the production technology of a kind of disjunctor socket disclosed in the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
According to Fig. 1, the invention provides a kind of production technology of disjunctor socket, comprise the following steps:
A, base patrix and base counterdie matched moulds, by the plastic raw materials after injection molding machine injection fusing, plastic raw materials enters cavity forming through charging runner, after die cavity fills up by plastic raw materials, screw in injection molding machine continues to apply pressure in die cavity until die cavity internal pressure rises to 126 MPas and keeps 7 seconds, above-mentioned pressurize technique is used for the plastic melt compacting in die cavity, increases the density of plastic melt in die cavity, the shrinkage phenomenon of plastics during to compensate cooling and shaping.Then the cooling body on base patrix cools 30 seconds, makes base cooling and shaping, finally utilizes the liftout attachment of base counterdie to eject base, base is injected with protruding riveting post.
B, plastic raw materials melted and is injection molded into shell, after shell demoulding cooling, stamping out the rivet hole matched with riveting post thereon.
C, the shell obtained by step b are assembled on the obtained base of step a, make riveting post through rivet hole.
D, add rivet hot post make its part of passing rivet hole soften.
Softening riveting post is pressed to rivet hole by e, use metal die, base and shell is riveted together after the cooling of riveting post.
When in step a, screw in injection molding machine continues to apply pressure in die cavity, the pressure in die cavity is passed to die wall surface by plastics, has the trend strutting mould, therefore needs suitable clamp force to carry out locked mode.Mould can strut by the mould power that rises under normal circumstances slightly, and the exhaust for mould has help; If but the mould power that rises is excessive, easily causes products formed burr, flash, even struts mould.Therefore, when selecting injection molding machine, the injection molding machine with enough large clamp force should be selected, to prevent the mould phenomenon that rises.
Wherein, in step e, base and shell are preferably flush riveting (rivet hole on shell caves inward, and uses the metal die of tack the riveting post of shell side to be all pressed into the recess of rivet hole), and flush riveting makes the junction of base and shell more smooth.
The production technology of a kind of disjunctor socket provided by the invention is by changing the connected mode of shell and base, make shell more solid and reliable be connected on base, shell loose or dislocation can be prevented, use hot riveting technique also to make production efficiency be improved simultaneously.
To the above-mentioned explanation of the production technology embodiment of disclosed a kind of disjunctor socket, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
