Abstract
In the disclosed method, two additional steps are added before clamping and injection molding procedures. Middle stage injection molding procedure is carried out for terminals. Then, cross structure of terminals is cut off completely. Terminals and middle stage injection molding piece are packed by using injection-molding material so as to complete injection-molding terminals. The invention raises quality of product of bundle of wires effectively, avoids risk in fabricating product so as to raise production efficiency and lowers cost.
Description
Technical field
The present invention relates to a kind of manufacture method of terminal of bunch product, be specifically related to a kind of injection moulding of the terminal to bunch product and the method for cut-out.
Background technology
Shown in Figure 1 is the schematic diagram of former wire harness CN05270102 terminal.Arrow refers to terminal cross structure 1, and being needs the position that cuts off in the course of processing.Prior art adopts increases the cutoff tool parts on injection mold, in injection moulding cross structure 1 is cut off.According to the design of original product, this terminal can run into following problem in the Shooting Technique process:
The first, the cut-off parts on the injection mold can run into edge of a knife wear problem.Produce the wire drawing problem if can cause terminal cross structure 1 to be cut the back, thereby cause this product to stay hidden danger because of the conducting short circuit with worn out edge of a knife cutting edge.Therefore cutting off the edge of a knife need regularly repair, and makes its maintenance sharp.And adding man-hour in large batch of terminal injection moulding, the situation of every batch terminal has difference.Though within the tolerance allowed band, the terminal of each batch is in hardness, size has fine distinction on the thickness, and the situation of each injection moulding also can be different.And these difference all can go up generation than large deviation to the time of cutoff tool finishing, have so just increased risk.
The second, because the no waste material disconnect mode of utilization causes the break distance instability.Distance between two truncation surfaces can produce very big difference because of the degree situation difference of each cut-out.Spacing distance when between two truncation surfaces is too small, can produce electric discharge phenomena during conducting.
The 3rd, increased the difficulty of checking.After finishing, the product injection moulding will carry out final inspection to product.Because of the working properties of product, determined that its difficulty of check is quite big.After the product injection moulding, its fracture place is difficult to the naked eye discover like disconnected non-disconnected situation.Wire drawing situation when some product injection mouldings is cut off between two truncation surfaces can only just can be discovered with microscope, and that the short circuit problem that wire drawing caused is a finished product is unallowable.Left metal was cut and can be produced nondirectional migration when secondly two sections was cut off, even if product has passed through the high pressure check, product itself still has the hidden danger of short circuit.
The risk of having scrapped when above three point problem has all increased finished product, as fail to be effectively controlled, will bring massive losses to enterprise after sending as qualified product.
Therefore, the present invention is directed to the above product that analyzes and cut off the problem that is produced because of injection moulding, proposed a kind of manufacture method of Wiring harness terminal, it can effectively reduce existing risk in the manufacture process.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of Wiring harness terminal, it can improve the quality of Wiring harness terminal product, and evades the risk in the manufacturing.
The present invention is achieved in that and at first carried out a neutron injection moulding that before Wiring harness terminal is being pressed then that terminal is original metal cross structure cuts off fully, afterwards this terminal is being pressed, and this terminal is carried out final injection moulding.
Location when more preferably, described injection moulding neutron is guaranteed the linking between each terminal and guaranteed final injection moulding in mould.
With injected plastics material this terminal is integral together with described injection moulding neutron parcel when more preferably, this terminal being carried out final injection moulding.
More preferably, the injected plastics material of described injection moulding neutron and described terminal is a commaterial.
The present invention original pressing and Shooting Technique between increased the twice processing step, three problems having avoided prior art to mention fully, both the quality of Wiring harness terminal product can be effectively improved, and the risk of producer in this product process of production can be evaded.
Description of drawings
Shown in Figure 1 is the schematic diagram of former wire harness CN05270102 terminal.
The injection moulding of the neutron that before terminal is being pressed, is carrying out when being the invention process shown in Figure 2.
Shown in Figure 3 when being the invention process the cross structure between terminal be completely severed.
Label
1 terminal cross structure, 2 injection moulding neutrons
Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is described in further detail.
At first, as shown in Figure 2, carried out the injection moulding of an injection moulding neutron 2 before terminal is being pressed, the injection moulding neutron 2 that this increases is in order to play the effect of original metal cross structure 1, also prepare for excising cross structure 1 together down in location when having guaranteed final injection moulding between terminal.Then as shown in Figure 3, metal cross structure 1 original between terminal is cut off fully.Pressing and final injection moulding operation various risks and the issuable defective that just can avoid prior art when metal cross structure 1 cuts off, to be brought thus through entering into terminal again after the above twice processing step.After finishing the terminal injection moulding, neutron 2 will be wrapped up by the injection molding body of same material and become one.So both finished excision work, also finished the operation requirement of injection moulding, avoided more fully because of cutting off the various quality problems that instability causes to virgin metal cross structure 1.Therefore the present invention can effectively improve the quality and the efficient of Wiring harness terminal injecting products, and has evaded existing risk in the product manufacturing.
Above-described embodiment is only in order to illustrate technological thought of the present invention and characteristics; its purpose is to make those of ordinary skill in the art can understand content of the present invention and implements according to this; the scope of this patent also not only is confined to above-mentioned specific embodiment; be all equal variation or modifications of doing according to disclosed spirit, still be encompassed in protection scope of the present invention.
