Description

A kind of automobile reading lamp bracket mould

Technical field

This utility model relates to a kind of auto parts and components mould, particularly relates to a kind of automobile reading lamp bracket mould.

Background technology

Middle reading lamp in car is mainly made up of base, reading lamp support, protecgulum, transparency cover, control turn-knob.The quality of existing domestic middle reading lamp reaches a standard the most completely, there is service life short, the problem that replacement frequency is high；The topmost parts wherein not passed a test or reading lamp support, because being provided with multiple electrical contact copper sheet insert, this design relating to reading lamp support mould therefor and manufacturing technology in the structure of reading lamp support.Reading lamp bracket mould includes dynamic model (reverse side mould) and quiet mould (positive face mould), conventional method is directly to be inserted on quiet mould by electrical contact copper sheet on injection machine at present, what a is often inserted, it is molded one, is inserted into the next one, so circulates, work efficiency is extremely inefficient, simultaneously as it inserts is directly to insert on quiet mould on injection machine, it is difficult to hold the flatness of electric contact point.Chinese patent ZL201020049853.1 discloses a kind of automobile middle reading lamp bracket die, it increases by one for the mobile mould pre-installing electric contact point on the basis of conventional dynamic model and quiet mould, mobile mould is spacing on quiet mould, this addresses the problem the problem that efficiency is low and flatness is the highest of common manufacturing method.But the when of due to the demoulding, the center hole wall of mobile mould is attached in the knob hole of product, on the one hand the knob hole of product has the burr that turn up, the condition causing product is the most regular, on the other hand, this point adhesive force all can cause mobile mould to drop it cannot be guaranteed that mould is moved in each die sinking together with product.

Summary of the invention

This utility model provides a kind of automobile reading lamp bracket mould, utilizes its injecting products condition good and mobile mould die sinking does not falls out.In order to realize foregoing invention purpose, this utility model have employed techniques below means:

A kind of automobile reading lamp bracket mould, including quiet mould and dynamic model；Positive surface model and the reverse side model of reading lamp support it is respectively provided with on described quiet mould and dynamic model；Also include a mobile mould, described mobile mould arranges the pin holes of electric contact point；Being provided with the spacing hole of spacing holding movable mould on described dynamic model, when described mobile mould is placed in spacing hole, the position of pin holes is relatively fixed the position of electric contact point on reverse side model；Arranging the cylinder of a shaped support knob hole on described dynamic model, what the when of matched moulds, cylinder was vertical closely withstands positive surface model；A centre bore is offered at the center of described mobile mould, and centre bore can be enclosed within cylinder closely.

The beneficial effects of the present invention is: mobile mould is spacing is arranged on dynamic model so that during die sinking product and movement mould all the time together with；Utilize cylinder molding knob hole together with positive surface model so that the front edge of knob hole is smooth, it is ensured that condition.

Detailed description of the invention

Below in conjunction with the accompanying drawings, the preferred implementation of automobile reading lamp bracket mould a kind of to this utility model is described in detail:

As depicted in figs. 1 and 2, this automobile reading lamp bracket mould includes quiet mould 1 and dynamic model 2, the positive surface model 11 in molding reading lamp support 4 front is set on quiet mould 1, arranging the reverse side model 21 of molding reading lamp support 4 reverse side on dynamic model 2, positive surface model 11 and reverse side model 21 collectively constitute the die cavity of reading lamp support 4.Arranging the cylinder 22 of a shaped support knob hole 42 on dynamic model 2, what the when of matched moulds, cylinder 22 was vertical closely withstands positive surface model 11.Offering on dynamic model 2 and put injection hole 24, injection hole 24 connects with reverse side model 21.

As shown in Fig. 3, Fig. 4 and Fig. 5, this automobile reading lamp bracket mould also includes a mobile mould 3, and its shape is substantially the rectangle of circular arc in a long limit.A centre bore 32 is offered at the center of mobile mould 3, and centre bore 32 can be enclosed within cylinder 22 closely.One surface of mobile mould 3 is forming surface, and this forming surface is provided with 10 fixing holes 31, and fixing hole 31 plugs with the fixing pin 12 on positive surface model 11 and coordinates, in order to the aperture around molding knob hole 42.The most vertical in the forming surface of mobile mould 3 offer four pin holes 33, in order to be previously inserted electric contact point 41.

Offering a spacing hole 23 as in figure 2 it is shown, vertical on dynamic model 2, the profile of its shape and mobile mould 3 closely cooperates mutually.Cylinder 22 is positioned at spacing hole 23, and mobile mould 3 is spacing when being placed in spacing hole 23, and centre bore 32 is just enclosed within cylinder 22, and now, pin 12 and the position alignment of electric contact point 41 are just fixed with on positive surface model 11 in the position of fixing hole 31 and pin holes 33.

During use, quiet mould 1 is contained in the fixing end of injection machine, dynamic model 2 is contained in the mobile terminal of injection machine, it is plugged the most in advance in the spacing hole 23 that the mobile mould 3 of electric contact point 41 loads dynamic model 2, matched moulds, now fixes pin 12 and inserts in fixing hole 31, and the forming surface of positive surface model 11, reverse side model 21 and mobile mould 3 collectively constitutes the die cavity of automobile reading lamp support 4, it is molded in die cavity by injection hole 24 again, formed product.

Being molded rear die sinking, owing to mobile mould 3 is between product and dynamic model 2, and positive surface model 11 is the most smooth, the most first product and mobile mould 3 are together ejected in company with dynamic model 2, the front of demoulding product, then product is taken off together with mobile mould 3 from dynamic model 2, complete the demoulding.Owing to mobile mould 3 is positioned at the reverse side of product, therefore the front flat smooth of product knob hole 42 during injection, it is ensured that condition.
