Description
Technical field
The present invention relates to a kind of moulding process, particularly relate to a kind of terminal and bend one-step shaping technique in mould internal cutting off.
Background technology
The mold insert molding mode that conventional window lifting switch adopts, being after individually terminal is cut off molding outside plastic mould, put injection mo(u)lding together with plastic cement in plastic mould into for another one, processing technique step is many, so not only cost is high, and the product quality after molding is bad.
Summary of the invention
It is an object of the invention to provide a kind of cost low and the terminal of product quality can be improved bend one-step shaping technique in mould internal cutting off.
For achieving the above object, the present invention provides a kind of terminal to bend one-step shaping technique in mould internal cutting off, and this technique comprises the steps:
(1) offer is provided with the plastic mould of drift, thimble and location mold insert and is provided with the terminal of centre hole and connecting portion, under described plastic mould folding condition, described terminal is put into the lay-down position of described plastic mould and inserts centre hole below terminal by the insertion section of thimble and withstand terminal below terminal with Primary Location terminal by the shoulder wider than insertion section of thimble；
(2) below terminal, terminal is compressed by positioning mold insert in the first stage of plastic mould matched moulds；
(3) while the second stage of plastic mould matched moulds, by drift, the connecting portion of terminal is cut off bending；
(4) product is formed toward injection moulding in plastic mould；
(5) ejecting product.
It is preferred that the terminal in step (1) is at least two-layer and the centre hole mutual dislocation in terminal setting up and down and setting up and down.
It is preferred that drift in step (1) and location mold insert are distributed in the both sides up and down of terminal respectively, and drift and location mold insert shift to install.
It is preferred that the connecting portion of the terminal in step (3) cuts off bending is subsequently formed two independent terminals.
It is preferred that also include a step exiting drift between step (3) and step (4).
Compared with prior art, the terminal of the present invention bends one-step shaping technique owing to can a step complete to cut off bending and injection mo(u)lding in described plastic mould in mould internal cutting off, thus not only reducing processing technique, decrease number of molds, reduce production cost, and the size of terminal can be made to be more prone to control in plastic mould internal cutting off bending terminal, and be only bending and incomplete cut-off, insulating properties can be increased, improve the quality of product.
By description below and in conjunction with accompanying drawing, the present invention will become more fully apparent, and these accompanying drawings are used for explaining embodiments of the invention.

Detailed description of the invention
With reference now to accompanying drawing, describing embodiments of the invention, element numbers similar in accompanying drawing represents similar element.
Refer to Fig. 1-4, bend the specific embodiment of one-step shaping technique for terminal of the present invention in mould internal cutting off, this technique comprises the steps:
(1) providing plastic mould 1 and one layer of terminal 2, described plastic mould 1 is provided with drift 11, thimble 12 and location mold insert 13 and a lay-down position.Described terminal 2 is provided with centre hole 21 and connecting portion 22.Described terminal 2 is put into the lay-down position of described plastic mould 1 under described plastic mould 1 folding condition, now described drift 11 is positioned at directly over the connecting portion 22 of described terminal 2, and described thimble 12 and described location mold insert 13 are positioned at the lower section of described terminal 2 and are positioned at the sides adjacent of described connecting portion 22, described drift 11 and described location mold insert 13 shift to install, by being inserted by described thimble 12 in described centre hole 21 with by described terminal 2 Primary Location.
(2) compressed by the described terminal 2 of described location mold insert 13 in the first stage of described plastic mould 1 matched moulds.
(3) by described drift 11, the connecting portion 22 of described terminal 2 being cut off bending while the second stage of described plastic mould 1 matched moulds, the connecting portion 22 of described terminal 2 cuts off bending and is subsequently formed two independent terminals.
(4) described drift 11 is exited.
(5) product is formed toward injection moulding in described plastic mould 1.
(6) ejecting product.
Complete to cut off bending and injection mo(u)lding by a step in a plastic mould 1, thus not only reducing processing technique, decrease number of molds, reduce production cost, and the size of terminal 2 can be made to be more prone to control in plastic mould 1 internal cutting off bending terminal 2, and it is only bending and incomplete cut-off, it is possible to increase insulating properties, improve the quality of product.
Refer to Fig. 5, it is that terminal of the present invention bends the one-step shaping technique specific embodiment for automobile glass elevating switch in mould internal cutting off, the present embodiment and above-mentioned first embodiment are distinctive in that: step (1) provides two-layer terminal 2, and described plastic mould 1 is provided with two lay-down positions setting up and down.Putting into the two-layer terminal 2 of lay-down position of described plastic mould 1 centre hole 21 mutual dislocation in two-layer terminal 2 setting up and down and setting up and down, the present embodiment is identical with the effect of above-described embodiment.
Terminal of the present invention bends one-step shaping technique in mould internal cutting off can also have other embodiments, the terminal 2 of more than three layers or three layers can be placed in plastic mould in other embodiments, and terminal 2 more than three layers or three layers is in setting up and down, the present embodiment is identical with the effect of above-described embodiment.
As mentioned above, described terminal bends one-step shaping technique owing to can a step complete to cut off bending and injection mo(u)lding in described plastic mould 1 in mould internal cutting off, thus not only reducing processing technique, decrease number of molds, reduce production cost, and the size of terminal 2 can be made to be more prone to control in plastic mould 1 internal cutting off bending terminal 2, and be only bending and incomplete cut-off, insulating properties can be increased, improve the quality of product.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in embodiment disclosed above, and should contain amendment, the equivalent combinations that the various essence according to the present invention carries out.
