Description

Automobile reading lamp props up frame mould

Technical field

The utility model relates to a kind of automobile component mould, particularly relates to automobile reading lamp and props up frame mould.

Background technology

Middle reading lamp in car is primarily of base, reading light support, protecgulum, transparency cover, control turn-knob composition. The quality of existing domestic middle reading lamp does not also reach a standard completely, there is work-ing life short, the problem that replacement frequency is high; The topmost parts wherein not passed a test or reading light support, because being provided with multiple electrical contact copper sheet insert in the structure of reading light support, this just relates to the designing and making technology of reading light support mould therefor. Reading light props up frame mould and comprises dynamic model (reverse side mould) and quiet mould (positive face mould), current ordinary method is directly inserted on quiet mould by electrical contact copper sheet on injection moulding machine, what a is often inserted, injection moulding one, then insert the next one, so circulate, working efficiency is very low, meanwhile, owing to its insertion is directly insertion on quiet mould on injection moulding machine, it is very difficult to hold the planeness of electric contact point. Chinese patent ZL201020049853.1 discloses a kind of automobile middle reading lamp bracket die, it increases by one for pre-installing the mobile mould of 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 planeness is not high of conventional manufacture method. But time due to the demoulding, the center hole wall of mobile mould is attached in the knob hole of product, the knob hole of product has the burr that turn up on the one hand, cause the product of product not too regular mutually, on the other hand, this point sticking power can not ensure that each die sinking is moved mould and all together with product, mobile mould can be caused to drop, move to replacing and be molded as inconvenience.

Summary of the invention

The utility model provides automobile reading lamp and props up frame mould, utilizes its injecting products product lover and die sinking time shift dynamic model replacing convenience. In order to realize foregoing invention object, the utility model have employed following technique means:

Automobile reading lamp props up frame mould, comprises quiet mould and dynamic model; Described quiet mould and dynamic model arrange positive surface model and the reverse side model of reading light support respectively; Also comprise a mobile mould, described mobile mould arranges the pin holes of electric contact point; The spacing hole being provided with spacing holding movable mould on described dynamic model, when described mobile mould is placed in spacing hole, the position of pin holes is fixed on the position of electric contact point on reverse side model relatively; Described quiet mould arranges the cylinder of shaping knob hole;

Described mobile mould arranges centre hole; Described centre hole is enclosed within cylinder.

The useful effect 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 shaping knob hole together with positive surface model so that the front edge of knob hole is smooth, ensure that product phase; Cylinder is located on quiet mould, takes out very convenient when changing the mobile mould on dynamic model.

Embodiment

Below in conjunction with accompanying drawing, the preferred implementation that the utility model automobile reading lamp props up frame mould makes detailed description:

As depicted in figs. 1 and 2, this automobile reading lamp props up frame mould and comprises quiet mould 1 and dynamic model 2, quiet mould 1 arranges the positive surface model 11 in shaping reading light support 4 front, arranging the reverse side model 21 of shaping reading light support 4 reverse side on dynamic model 2, positive surface model 11 and reverse side model 21 form the die cavity of reading light support 4 jointly. Arranging the cylinder 13 of a shaped support knob hole 42 on quiet mould 1, what when closing mould, cylinder 13 was vertical withstands reverse side model 21. Offering on dynamic model 2 and put injection hole 24, injection hole 24 is connected with reverse side model 21.

As shown in Fig. 3, Fig. 4 and Fig. 5, this automobile reading lamp props up frame mould and also comprises a mobile mould 3, and its shape is a long limit substantially is the rectangle of circular arc. A centre hole 32 is offered at the center of mobile mould 3, and centre hole 32 can be enclosed within cylinder 13 closely. A surface of mobile mould 3 is molding surface, and this molding surface is provided with 10 fixed orificess 31, and fixed orifices 31 plugs with the locking pin 12 on positive surface model 11 and coordinates, in order to the aperture around shaping knob hole 42. Also vertical in the molding surface of mobile mould 3 offer four pin holes 33, in order to insert electric contact point 41 in advance.

As shown in Figure 2, vertical on dynamic model 2 offering a spacing hole 23, its shape closely cooperates mutually with the profile of mobile mould 3. The position of cylinder 13 is in spacing hole 23 and parallel with it, it is mobile that mould 3 is spacing is placed in spacing hole 23, close mould time centre hole 32 be just enclosed within cylinder 13, now, the position of fixed orifices 31 and pin holes 33 just with the position alignment of locking pin 12 on positive surface model 11 and electric contact point 41.

During use, quiet mould 1 is contained in the inboardend of injection moulding machine, dynamic model 2 is contained in the mobile terminal of injection moulding machine, the mobile mould 3 being plugged electric contact point 41 in advance loads in the spacing hole 23 of dynamic model 2, closing mould, now locking pin 12 inserts in fixed orifices 31, the die cavity of the common formed automobile reading light support 4 of molding surface of positive surface model 11, reverse side model 21 and mobile mould 3, again by injection hole 24 to injection moulding in die cavity, formed product.

Injection moulding complete after die sinking, owing to mobile mould 3 is between product and dynamic model 2, and positive surface model 11 is comparatively smooth, therefore first product and mobile mould 3 is together ejected in company with dynamic model 2, and product is taken off by the front of demoulding product again from dynamic model 2, completes the demoulding. Now cylinder 13 is extracted out in centre hole 32, it is only necessary to detain the centre hole 32 moving mould 3, just can be taken off from dynamic model 2 by mobile mould 3 very easily, change very convenient. Owing to mobile mould 3 is positioned at the reverse side of product, knob hole 42 is directly shaping with positive surface model 11 and become by cylinder 13, and therefore the front flat smooth of product knob hole 42 during injection moulding, ensure that product phase.
