Release and depart from the completion backform action of core 24, operating personnel directly remove plastic is molded.
When removing after shaping plastic matched moulds again, in injection machine push rod elder generation retraction lathe, then being moved on lathe moving platen makes
Dynamic model component 2 is fitted with cover half component 1, and a push pedal release link 37 and secondary push plate release link 38 are being led during matched moulds
A push pedal 31, secondary push plate 32, push rod 36 and sprue puller 39 is driven synchronously to be pushed back by solid plate 12 under the guide effect of post 231
To original state；The right side inclined-plane of its ramp structure extruding side core sliding block 241 in the folding process of briquetting 391 of sprue puller 39
Structure, makes side core sliding block 241 be moved to the left compressed side extracting cartridge spring 242, and then make dynamic model component 2 accurate with cover half component 1 right
Close, complete mould assembling action.
In for automobile indicator lampshade mounting frame plastic inner chamber with mold the vertical hole in button side in opposite direction or
The labyrinths such as muscle, because size is smaller and position is generally compacter, are difficult to take directly once opening vertically or horizontally
Mould realizes core pulling, as a further improvement on the present invention scheme, as shown in fig. 6, being additionally provided with movable insert on described core 24
The installation direction of mounting hole or groove and movable insert 243, movable insert mounting hole or groove is identical with die sinking direction, movable insert
243 are movably arranged in movable insert mounting hole or groove, and the exposed junction of movable insert 243 is arranged to pacify with automobile indicator lampshade
The inner surface portion appearance and size identical surface texture of plastic is shelved, because vertical hole or muscle are with opposite direction with die sinking
The labyrinths such as button side, during die sinking, movable insert 243 hooks the synchronous movable insert mounting hole for pusheding away from core 24 by plastic
Or groove, operating personnel will be molded after plastic will need to only be removed when directly removing on the self-forming plastic of movable insert 243 and reinstall
Matched moulds is carried out again in the movable insert mounting hole or groove for entering core 24.
For the ease of movable insert 243 die sinking when smoothly follow shaping plastic depart from core 24, as it is of the invention enter
One step improvement project, the movable insert mounting hole or groove inwall of described core 24 are arranged to taper face, described movable insert
243 mounting surface is arranged to the taper face coordinated with the movable insert mounting hole or groove inwall of core 24.
During in order to prevent movable insert 243 to be movably arranged in the movable insert mounting hole of core 24 or groove due to vibrations or
Other reasonses cause its position to change, and then cause that plastic parts moulding effect is poor, even produce waste product, as it is of the invention enter
One step improvement project, the described installation end of movable insert 243 or the movable insert mounting hole of described core 24 or groove
Installation site is provided with magnetic material coating, and magnetic material coating can be inhaled after installation activity mold insert 243 to movable insert 243
Attached positioning.
Process for convenience and change, and ensure that push rod 36 and secondary push plate release link 38 are accurately positioned in secondary push plate 32
Above and firmly with secondary push plate 32 it is fixedly connected, as shown in Figure 4, Figure 5, scheme, described as a further improvement on the present invention
The membrane module 3 that pushes away also include push rod supporting plate, push rod supporting plate is arranged on the top of secondary push plate 32 and connection fixed thereto, described
Push rod 36 and the bottom of secondary push plate release link 38 be fixedly mounted in secondary push plate 32 by push rod supporting plate.
This automobile indicator lampshade mounting frame injection mold in core 24, near sprue puller through hole due to being provided with side core
Slider containment chamber and side core sliding block 241, the briquetting 391 on side core sliding block 241 and sprue puller 39 are oblique by what is cooperated
Structure laminating in face is installed, side core sliding block 241 is connected by side extracting cartridge spring 242 with core 24, briquetting 391 is provided with for releasing
The sub- sprue puller 392 of condensate, and membrane module 3 is pushed away including a push pedal 31 and secondary push plate 32, push pedal when die sinking and matched moulds
31 press close to secondary push plate 32 or separation process in the mobile reality of side core sliding block 241 is made by moving up and down for sprue puller 39
Existing side core-pulling and reset, sprue puller 39 is arranged such can be realized releasing sprue condensate and can realize interior side-drawing mechanism side type
The reset of core sliding block 241, is thus susceptible to realize the side core-pulling in intensive hole, buckle and muscle structure；Push pedal guide pillar 34 sets
Put can for a push pedal 31 move guiding, support positioning secondary push plate 32, can limit again a release for push pedal 31 away from
From so as to ensure that the reliability of inner side core-pulling work；Simultaneously as side core sliding block 241, briquetting 391 and sub- sprue puller 392
Setting, therefore reduce mould difficulty of processing, manufacture and easy to maintenance, and ensure smoothly die sinking；In addition, with the split of core 24
The side core sliding block 241 and briquetting 391 of setting are conveniently replaceable, and improve the mold use life-span, and then ensure the precision of plastic, mould
Tool maintenance cost is relatively low；Due to being provided with the movable insert 243 of Split type structure, therefore can realize for carrying in inner chamber and open
The local injection moulding of the plastics of labyrinth such as mould is in opposite direction, the less vertical hole in button side of size or muscle, it is particularly suitable
It is larger but with dense holes, buckle and the isostructural complicated plastic of muscle in this kind of overall volume of automobile indicator lampshade mounting frame.
