Abstract
The invention discloses a manufacturing technology of an electronic cover plate main body for a motor inside a car. The electronic cover plate main body is made of plastic, and multiple metal electricity-conducting plates are annularly and sequentially inlaid in the electronic cover plate main body. The manufacturing technology of the electronic cover plate main body comprises steps as follows: A, a metal piece is placed in an injection molding machine for injection molding, so an injection-molded piece provided with the metal piece is formed, wherein the metal piece comprises an annular edge and the multiple metal electricity-conducting plates connected to the inner side of the annular edge, the metal electricity-conducting plates are connected with the annular edge by the aid of connecting strips, and the annular edge is exposed out of the injection-molded piece; and B, the annular edge is cut off. The manufacturing technology has the beneficial effects as follows: 1, the placing precision of the metal electricity-conducting plates in the injection-molded piece is high, and the metal electricity-conducting plates are placed once only, so that the production efficiency is improved, and the production cost is reduced; and 2, punching and injection molding are completed in one mold, the technology is simplified, and the production efficiency is improved.
Description
Technical field
The present invention relates to the manufacturing process of the electronics cover plate main body of motor in a kind of automobile.
Background technology
Generally, the moulding of band metal insert such as electronics cover plate main body needs two steps, first with stamping die by metal insert punch forming, then is put in mould of plastics by metal insert and is molded, thus obtains the product that we need.
Electronics cover plate assembly typically has 4 nugget genus conducting strips, need to be sequentially placed in mould of plastics by 4 nugget genus conducting strips, then be molded during injection.On the other hand but this method defect is obvious: on the one hand stamping parts unmanageable, during injection, put metallic conduction sheet inefficient, and easily occur leakage put, the phenomenon such as misplaced, percent defective is high.This not only affects the mold use life-span, also has a strong impact on whole product and pays.
Summary of the invention
In order to overcome existing electronics cover plate main body to manufacture the deficiency that efficiency is slow and percent defective is high, the present invention provides the manufacturing process of a kind of electronics cover plate main body manufacturing the wiper motor that efficiency is high, percent defective is low.
The present invention solves the technical scheme of its technical problem: the manufacturing process of the electronics cover plate main body of motor in a kind of automobile, described electronics cover plate main body is made of plastics, circularize above electronics cover plate main body and be inlaid with several metallic conduction sheets successively, the manufacturing process of described electronics cover plate main body comprises the following steps: a metalwork is put into injection in injection machine and formed the moulding of a band metalwork by A., described metalwork includes that a ring limit and several are connected on the metallic conduction sheet inside ring limit, described metallic conduction sheet is connected with described ring limit by connection strap, the outside at moulding is exposed on described ring limit.B. ring limit is excised.
Further, step A and B complete in a mould, and described mould has injection mould and punching mechanism simultaneously, and described punching mechanism includes several chippings, and described chipping alignment connection strap, during matched moulds, described chipping cuts off described connection strap.
Further, described metallic conduction sheet is provided with 4 and metalwork is stamping forming.
The beneficial effects of the present invention is: 1, in moulding, the placement precision of metallic conduction sheet is high, as long as and place once, improve production efficiency, reduce production cost.2, die-cut and be moulded in a mould and complete, simplify technique, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the electronics cover board body position view with metallic conduction sheet of the present invention.
Fig. 2 is the schematic diagram of the metalwork of the present invention.
Fig. 3 is the schematic diagram that punching mechanism of the present invention cuts away the ring limit of moulding.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
In conjunction with accompanying drawing 1 to 3, the manufacturing process of the electronics cover plate main body 1 of motor in a kind of automobile, described electronics cover plate main body 1 is made of plastics, circularize above electronics cover plate main body 1 and be inlaid with several metallic conduction sheets 2 successively, the manufacturing process of described electronics cover plate main body 1 comprises the following steps: a metalwork 3 is put into injection in injection machine and formed the moulding 4 of a band metalwork 3 by A., described metalwork 3 includes that a ring limit 5 and several are connected on the metallic conduction sheet 2 inside ring limit 5, described metallic conduction sheet 2 is connected with described ring limit 5 by connection strap 6, described ring limit 5 is exposed in the outside of moulding 4.B. ring limit 5 is excised.
Further, step A and B complete in a mould, and described mould has injection mould and punching mechanism simultaneously, and described punching mechanism includes that several chippings 7, described chipping 7 are directed at connection strap 6, and during matched moulds, described chipping cuts off described connection strap 6.
Further, described metallic conduction sheet 2 is provided with 4 and metalwork 3 is stamping forming.
The beneficial effects of the present invention is: 1, in moulding, the placement precision of metallic conduction sheet is high, as long as and place once, improve production efficiency, reduce production cost.2, die-cut and be moulded in a mould and complete, simplify technique, improve production efficiency.
