Description
Technical field
The present invention relates to work piece production technical field, more particularly to a kind of work piece production method.
Background technology
The technological process of workpiece is manufactured existing, it is common and can to produce various workpiece using the method for injection molding
A kind of means leaned on.Product is usually using rubber injection mold and plastic injection, and by using injection mold by product moulding by casting
It is mode common in Shooting Technique.The common methods of injection molding are：At a certain temperature, the plastic material that will be melted completely, with
Certain flow velocity, by running channel, enters die cavity from the entrance of mold from glue-feeder.It is demoulded after cooling and solidifying, removes glue-feeder
Locate extra solidification part, obtain finished work-piece, is further continued for subsequent processing.The surface quality of moulding increasingly becomes concern
Emphasis, be especially used for being assemblied in the workpiece of product external surfaces, coating quality, the smoothness on surface etc. are all particularly important.
Conventionally produced workpiece may need to contact with other extraneous process equipments during following process due to surface,
So that surface is likely to result in damage, or it is not easy to surface working process.
Invention content
In view of this, the present invention is intended to provide a kind of work piece production method, it can be easily to workpiece after the completion of injection molding
Follow-up secondary operation is carried out, and workpiece can be made to obtain preferably surface quality.
In order to achieve the above objectives, the embodiment of the present invention is realized in：
A kind of work piece production method comprising：
Injection molding forms the workpiece, and injection molding forms the support portion for being used to support workpiece, the support portion outside glue-feeder
It is integrally formed with the workpiece；
The workpiece to being connected with the support portion carries out secondary operation, in the secondary processing process, the support
Portion is used to support the workpiece.
Further, there is the workpiece inner side and outer side, the glue-feeder to be located at institute in the state of being fabricated to product
State the inside of workpiece.
Further, the support portion is between the entrance of injection mold and the die cavity for limiting the workpiece topography
It is formed in channel.
Further, in the work piece production method, at least two glue-feeders is provided with and are molded, support portion
Both ends are respectively connected at two glue-feeders.
Further, the workpiece have length direction, at least two support portions be bar shaped, the two of the support portion
End is connected to both sides of the workpiece on length extending direction.
Further, at least two support portions, at least two branch are connected on the workpiece of injection molding
Support part is spaced setting on the length direction of the workpiece.
Further, the workpiece of injection molding is plate, and support zone described at least three is in the same of the workpiece
Face；The support portion is connected at the glue-feeder on the workpiece, and protrudes from the workpiece planarization at place.
Further, the secondary operation is that spray painting or plating, the support portion are consolidated in the secondary processing process
It is fixed, and keep the workpiece hanging.
Further, the secondary operation is plating, and it is flat that the support portion is used to support the processing in the electroplating operations
On platform.
Further, the work piece production method further includes：
The support portion is removed after the completion of the secondary operation.
The advantageous effect of the embodiment of the present invention is：
Compared with the existing technology, work piece production method of the present invention has the advantage that：
(1) work piece production method of the present invention includes the secondary operation of injection-molded work and workpiece.It is completed in injection molding
Afterwards, it reserves at glue-feeder and is formed together with injection moulding process with the integrally formed support portion of workpiece, the support portion.
In subsequent secondary processing process, support portion can play a supporting role to workpiece, workpiece need not touch operation platform surface,
The surface quality caused by contact, or the part surface caused by contact is avoided to be difficult to.In picking up work piece or fixation
When workpiece, it is not necessary to directly contact, can be come real by the support portion reserved on pickup (or fastening) workpiece to workpiece
It now picks up or fixed, break can be facilitated to carry out subsequent operation in this way, also ensure that the quality on surface is unaffected, improve
The usage experience of user.
(2) work piece production method of the present invention is in injection-molded work, since workpiece is specifically being assembled to use environment
There are inner side and outer side when middle, therefore the glue-feeder being molded is set to the inside of workpiece, to avoid workpiece after removal support portion into
Occur the trace blocked at Jiao Kou and influences aesthetics.The presentation quality of product can be improved in this way.Support portion is by injection mould
The material solidification in running channel between the entrance and die cavity of tool forms, therefore support portion is formed together with workpiece injection molding, no
Necessity is separately provided after work piece production, improves production efficiency.When the workpiece of production has length direction and forms strip,
Support portion is arranged into strips, and both ends are separately connected the both sides of workpiece, and at least two support portions are along the length direction of workpiece
On be alternatively arranged.Longer workpiece can so also can preferably be supported in subsequent process.
