Description
Technical field
The present invention relates to the injection mold structure of Bus headlamp lampshade, especially with respect to the core-pulling slide block machine of lampshade cover half
Structure.
Background technology
Automobile lamp as functor, while be also appearance member, increasingly become vehicle configuration and overall appearance to close weight
The part wanted, therefore have the requirement of higher to plastic component structure and technique.Lampshade require it is specious, novel, any surface finish, thoroughly
Bright and have certain intensity, lampshade is assembled with lamp housing using card base and click on fashion, the limit rib and card base coordinated on lampshade
Core pulling is needed, therefore, the motion state of Mold Core-pulling Mechanism will steadily, reliably, efficiently.
Original stationary mould for mould pulled core structure, using hydraulic oil cylinder driving core-pulling slide block move, complete cover half sliding block core pulling and
Homing action, but oil cylinder core-pulling mechanism volume is larger, increases die boundary dimensions, it is necessary to could be molded on large size plastic jetting-moulding device
Production, and core pulling and reseting procedure are unstable, and cavity core pulling sliding block has the potential risk of failure.
The content of the invention
The object of the present invention is to provide a kind of pop-up type slide block mechanism of injection mold, motion process is steady, reliable, high
Effect, meets requirement of the plastic product to appearance.
Technical solution provided by the invention is：
A kind of pop-up type slide block mechanism of injection mold, including cover half sliding block, are provided with inclined guide pillar, cover half on cover half sliding block
Spring eye is offered on sliding block, the axis of spring eye is parallel with the axis of inclined guide pillar, and compression spring is provided with spring eye, compression
Spring props up cover half sliding block, and cover half upper end of slide block is provided with limited block, and limited block is fixed on framed, and cover half slider bottom is set
There is drag hook, drag hook block is hooked in drag hook one end, and the drag hook other end is fixed on dynamic model, and drag hook block is fixed on cover half sliding block.
The inclined guide pillar and compression spring has two, is separately positioned on the both sides of cover half sliding block.
The cover half sliding block of the present invention moves, drag hook takes off under the collective effect of drag hook and spring along inclined guide pillar axis direction
From the drag hook block on cover half sliding block, cover half sliding block only continues to move under the elastic force of spring, until cover half sliding block encounter it is spacing
Block, plastic side rib and card base also spin off from cover half sliding block, and core pulling process is completed.The pop-up type slide block mechanism of mould
Motion process it is steady, reliable, efficiently, meet requirement of the plastic product to appearance.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention one.
Fig. 2 is schematic structural view of the invention two.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1,2, a kind of pop-up type slide block mechanism of injection mold, including cover half sliding block 3, is set on cover half sliding block 3
There is inclined guide pillar 1, spring eye is offered on cover half sliding block 3, the axis of spring eye is parallel with the axis of inclined guide pillar 1, is set in spring eye
Compression spring 2 is equipped with, compression spring 2 props up cover half sliding block 3, and 3 upper end of cover half sliding block is provided with limited block 6, and limited block 6 is fixed on
On framed, 3 bottom of cover half sliding block is provided with drag hook 5, and drag hook block 4 is hooked in 5 one end of drag hook, and 5 other end of drag hook is fixed on dynamic model
On, drag hook block 4 is fixed on cover half sliding block 3.Inclined guide pillar 1 and compression spring 2 have two, are separately positioned on cover half sliding block 3
Both sides.
Since the side structure of plastic is complicated, and the rib of plastic side is consistent with card base core pulling direction, can design
Core pulling is carried out on one cover half sliding block 3.Because 3 appearance and size of cover half sliding block is larger, in order to ensure its stable movement, cover half sliding block 3
Middle installation compression spring 2, is oriented to, spring eye axis direction is consistent with 1 axis direction of inclined guide pillar by two inclined guide pillars 1.Die sinking
Afterwards, under the action of elastic force, cover half sliding block 3 is moved along 1 axis direction of inclined guide pillar, moves a distance, and cover half sliding block 3 encounters limit
Position block 6, stop motion, at this time, plastic side rib and card base also spin off from cover half sliding block 3.
In the moment of die sinking, compression spring 2 is likely to occur and cover half sliding block 3 is flicked cannot immediately, it may appear that plastic is pulled
Phenomenon.To avoid the generation of the above problem, therefore, drag hook 5 is devised, drag hook 5 is installed on dynamic model 7, during die sinking, cover half sliding block
3 under the collective effect of drag hook 5 and compression spring 2, move along 1 axis direction of inclined guide pillar, and after moving a distance, drag hook 5 is de-
From the drag hook block 4 on cover half sliding block, cover half sliding block 3 only continues to move under the elastic force of compression spring 2, until cover half sliding block 3
Encounter limited block 6, plastic side rib and card base also spin off from cover half sliding block 3, and core pulling process is completed.
