Description

The shaped device of thin plug

The present invention relates to a kind of shaped device of thin plug, You Zhiyi can be accurately in the ejection formation process and is fixed the thin plug shaped device of flexible conductor wire rapidly.

The thin type plug is not owing to take up space, and perpendicular because of the outlet direction of its pin direction and conductor wire, difficultly extracted by accident, so the suitable practicality of tool.But the ejection formation manufacturing of relevant thin type plug, but there is the certain difficulty degree, that is, in the ejection formation process of thin type plug, how to control flexible conductor wire and accurately be positioned in the limited die cavity height, make it to be unlikely in the moulding displacement and cause to expose after the moulding and just become a key problem in technology.Look into, the forming method of thin type plug of commonly seeing has a kind of as Fig. 9 and molding mode shown in Figure 10, it is to utilize the skewer of thin and tool rigidity or blade to provide support with fixing, in the ejection formation process, regularly flexible conductor wire is clamped on the exact position of die cavity inside, and wherein skewer or blade can be withdrawn before the stage at molded final filler, allow plastics to flow in the left cavity of retraction blade, the perhaps back withdrawal of blade injectable loop ends and on mechanograph, leave the cavity, and the action in order to assist to bounce back, skewer or blade are made thin shape as much as possible, but there is a problem in right this, be that skewer or blade are made Bao Zhuanhou, it is can't possess the rigidity of filling part and make flexible conductor wire can not be positioned at desirable exact position, be with, other has an embodiments possible, be that these blades can be deposited in the mold, be drawn out of again behind setting and harden until plastic shaping material, and on this mechanograph, leave very little and thin cavity, though great influence can not caused to the mechanograph structure in right this cavity, but it can make the finished product outward appearance stay depression, and is very not attractive in appearance; In addition, above-mentioned molding mode must be located at down conductor wire in the half module die cavity of side mold earlier, utilize skewer or blade with its maintenance again, and cooperate the upside mould to cover the downside mould, by fluid injection crossing current road perfusion plastic shaping mechanograph, see it, there is the problem of a manufacturing speed in it, that is in whole ejection formation process, the above-mentioned case of commonly using must be gone through follow procedure: 1. install-element is installed in the die cavity

Before upper and lower mould is not closed, plug base pin is placed in counterdie together with flexible conductor wire

In the die cavity of tool, plug base pin is passed by the reserving hole channel of following die cavity, and flexible conduction

Line then is fastened on the grasping end place of aforementioned skewer (or blade) one by one according to its preset path;

If the preset path of this flexible conductor wire in die cavity is longer, then above-mentioned skewer number

Amount will increase thereupon, that is, flexible conductor wire must spend the more time in order to each

The grasping end of skewer fixes, so that flexible conductor wire gets in limited die cavity height

With accurate location.2. mutually closed 3. material feedings of mold closing-upper and lower mould-injection heat is melted plastics in die cavity

The plastics that utilize heat to melt inject die cavity, and through cooling plastics are solidified in die cavity,

In the terminal time in this stage, aforementioned skewer can withdraw from or still stay in the die cavity.4. die sinking-upper and lower mold open

Again, above-mentioned known forming method only can be selected for use the plastics of single material to carry out heat and melt ejaculation, and this can't take into account the functional requirement of various enforcement occasions, for example: 1. plastics really up to the mark

Though can make the thin type plug have preferable intensity, the plug end is connected with power line

The place, it should possess suitably flexible requirement just can't reach, and cohesive end really up to the mark, meeting

During feasible enforcement, path of this place's power line lacks flexibility, difficult adaptation varying environment

Demand.2. cross soft plastics

Though tool is flexible cohesive end suitably, can make the plug of thin type lack suitable intensity, insert

Body very easily is out of shape when unloading plug (as pull out) because of external force, if this distortion is often sent out

Give birth to, the contact of inner conductive line just breaks away from or loose contact easily, easily gives birth to dangerous.3. heat labile plastics

The electrical equipment (as electric iron) of the big electric current of some uses, header body can produce higher

Temperature, this moment thermo-labile as the plastics of header body, header body easy because of high temperature soft

Change, cause unexpected even cause the plug distortion.4. selector closes and states the plastics of every requirement

Select plastics neither too hard, nor too soft, fireproofing and heat resistant to carry out ejection formation, will make the plastics cost

Significantly improve the market competition of unfavorable product.

In addition, utilize and commonly use the thin type plug of injection forming method manufacturing, its finished product outward appearance lacks variation, difficult performance product texture or special demand, and simple product appearance for the requirement of the different patterns between different orders, also is difficult to strain.
