Abstract
The invention discloses an injection-molding manufacturing technology of a door sheet pull handle for an automobile. The door sheet pull handle is a metal product. The injection-molding manufacturing technology comprises the following steps: a. welding formation: stamping and welding a metal sheet part to form a metal insert of the door sheet pull handle; b. primary injection molding: placing and fixing the metal insert formed by welding in a primary injection mold and carrying out primary package injection molding; c. secondary injection molding: taking the metal insert subjected to primary package injection molding out of the primary injection mold, checking, and then placing and fixing the metal insert in a secondary injection mold to carry out secondary package injection molding, thus manufacturing the door sheet pull handle for the automobile; and d. product inspection: taking the door sheet pull handle for the automobile out of the secondary injection mold, cooling in a normal-temperature environment, and carrying out routine inspection. By virtue of the injection-molding manufacturing technology of the door sheet pull handle for the automobile, the cost is lowered, the rejection rate is reduced and the appearance quality is enhanced; and the requirement on the style of the door sheet pull handle is met.
Description
Technical field
The present invention relates to a kind of injection moulding manufacturing process, belong to the field of automobile decoration piece, be specifically related to the manufacturing process of the automobile door plate handle of quadric injection mould.
Background technology
In recent years since, China's auto parts and components and accessory manufacturing income from sales and total profit present rapid growth situation, and the industry degree of prosperity is significantly surging, and the industry benefit is significantly gone up.
Automotive upholstery door-plate handle is as being used for driver and the necessary part of passenger getting on/off, and the uniformity and the style that when satisfying the load-bearing requirement, also will satisfy interior trim part outward appearance are unified.Existing door-plate handle part is generally accomplished by the inserts injection moulding, at first accomplishes the moulding of metal insert, again through the final coated metal spare of metal insert injection mold, reaches the appearance requirement of plastic material.But because the existence of metal insert, to material in the mould flow and all there is certain influence in cooling, finally can exert an adverse impact to outward appearance.
Summary of the invention
The technical problem that the present invention mainly solves provides the injection moulding manufacturing process of automobile door plate handle, has reduced cost, reduces scrappage, has improved the quality of outward appearance, and has satisfied the style requirement of door-plate handle.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the injection moulding manufacturing process of automobile door plate handle is provided, and described door-plate handle comprises the steps: for metallic article
A, welding fabrication are welded into the metal insert that door-plate is shaken hands with the punching press of metallic plate metal parts;
B, an injection moulding are put into injection mold one time with the metal insert of welding fabrication, are fixed in injection mold, wrap up injection moulding for the first time;
C, quadric injection mould take out the metal insert that wraps up for the first time after the injection moulding from an injection mold, it is fixing to put into the quadric injection mould mould after the inspection, carry out the injection moulding of secondary parcel, process the door-plate handle that automobile is used;
D, the examination and test of products are taken out from the quadric injection mould mould processing the door-plate handle that automobile uses, and are placed on normal temperature under and cool off, and carry out routine inspection.
In preferred embodiment of the present invention, among the described step b, when wrapping up injection moulding for the first time, the degree of coated metal sheet-metal parts is 60-80%.
In preferred embodiment of the present invention, among the described step c, the time of carrying out the injection moulding of secondary parcel is 45 seconds.
The invention has the beneficial effects as follows: the injection moulding manufacturing process of automobile door plate handle of the present invention; Through the preliminary parcel of an injection moulding and the final parcel of injection moulding for the second time; Improved the quality of metal insert to outward appearance; And satisfy the style requirement of door-plate handle, reduced cost and reduced scrappage.
Description of drawings
Fig. 1 is the flow chart of injection moulding manufacturing process one preferred embodiment of automobile door plate handle of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the invention provides the injection moulding manufacturing process of automobile door plate handle, comprise following operating procedure:
The injection moulding manufacturing process of automobile door plate handle, described door-plate handle comprises the steps: for metallic article
A, welding fabrication are welded into the metal insert that door-plate is shaken hands with the punching press of metallic plate metal parts;
B, an injection moulding are put into injection mold one time with the metal insert of welding fabrication, are fixed in injection mold, wrap up injection moulding for the first time;
C, quadric injection mould take out the metal insert that wraps up for the first time after the injection moulding from an injection mold, it is fixing to put into the quadric injection mould mould after the inspection, carry out the injection moulding of secondary parcel, process the door-plate handle that automobile is used;
D, the examination and test of products are taken out from the quadric injection mould mould processing the door-plate handle that automobile uses, and are placed on normal temperature under and cool off, and carry out routine inspection.
Among the above-mentioned steps b, when wrapping up injection moulding for the first time, the degree of coated metal sheet-metal parts is 60-80%; Among the step c, the time of carrying out the injection moulding of secondary parcel is 45 seconds.
With metallic plate metal parts bend forming, be welded into the metal insert of door-plate handle then, and carry out dimension control; It is fixing that metal insert is put into an injection mold, carries out mold-closing injection, takes out the back part of preliminary parcel is checked, whether the inspection part exists distortion; The part of parcel is for the first time put into the quadric injection mould mould, finally wrap up injection moulding, process the door-plate handle that automobile uses, take out back inspection door-plate handle outward appearance from the quadric injection mould mould and whether have the bad of shrink mark overlap.
The injection moulding manufacturing process of the automobile door plate handle that the present invention discloses; Through the preliminary parcel of an injection moulding and the final parcel of injection moulding for the second time; Improved the quality of metal insert, and satisfied the style requirement of door-plate handle, reduced cost and reduced scrappage outward appearance.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
