Description
[technical field]
The present invention relates to a kind of mold mechanism, particularly a kind of oblique core-pulling mechanism of mould.
[background technology]
Work as injecting products, such as the shell of digital camera, PDA etc., profile is the back-off shape, and the inclined hole central axis in the product and mold center's line have the angle of inclination, and product appearance needs to adopt oblique core-pulling mechanism when requiring not allow parting line in the hole.Existing oblique core-pulling mechanism generally is to adopt the core-pulling mechanism of big slide block or oil cylinder to come the inclined hole of shaped article, yet this mechanism structure is complicated, the higher and poor stability of cost, and receive the restriction of die space sometimes and can't in mould, adopt.
[summary of the invention]
In order to overcome above-mentioned defective, the object of the present invention is to provide a kind of simple in structure, cost is lower and the oblique core-pulling mechanism of stable high mould.
For achieving the above object, the present invention provides a kind of oblique core-pulling mechanism, is applied to a mould; The inclined hole that is used for moulding one product; This mould comprises upper mounted plate, caster, male model plate and the bottom plate that is linked in sequence from top to bottom, it is characterized in that, this oblique core-pulling mechanism comprises:
One shutter, one of which end are fixed on this caster, and the other end is fixed on this male model plate;
One goes into son; Be arranged in this male model plate; The one of which end extends to the inclined hole that is used for this product of moulding when matched moulds in the die cavity of this mould, and its other end is a stress surface, and this is gone into also to be provided with one on the son and is used for when die sinking, providing elastic force to make this go into the flexible member that son withdraws from product;
One male model fagging is arranged between this male model plate and this bottom plate;
One shovel base is positioned at the below that this goes into son, and the one of which end is fixedly arranged on this male model fagging, and the other end is a force surface, and the force surface of this shovel base contacts with this stress surface of going into son when matched moulds; And
One pull bar, its lower end are fixedly arranged on this male model fagging, and its main body can be arranged in this male model plate up and downly, and the motion to this male model fagging when this pull bar is used for die sinking is carried out spacing.
Compared to prior art; The present invention is through increasing a male model fagging; Be incorporated into son through the shovel basigamy on this male model fagging coupling mechanism force is provided; This spring of going on the son provides the power of loosing core, and this goes into the sub product back-off part that breaks away from earlier along oblique extraction in the moment of die sinking, and mould continuation die sinking ejects product then.Adopt that this oblique core-pulling mechanism is simple in structure, the demoulding is stable and cost is low, is suitable for producing the product that all kinds of inclined hole central axis and mold center's line have the angle of inclination.
[description of drawings]
Structural representation when Fig. 1 illustrates the oblique core-pulling mechanism matched moulds of the present invention state.
Structural representation when Fig. 2 illustrates the oblique core-pulling mechanism of the present invention die opening state first time.
Structural representation when Fig. 3 illustrates the oblique core-pulling mechanism of the present invention die opening state second time.
[specific embodiment]
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Please, adopt the oblique core-pulling mechanism of the present invention to be applied to a mould, be used for the inclined hole of moulding one product 10 with reference to Fig. 1.This mould comprises the upper mounted plate 100 that is linked in sequence, a caster 200, a male model plate 300, a liftout plate 500, a bottom plate 600 from top to bottom; This oblique core-pulling mechanism comprises that a male model fagging 400, goes into son 20, one shovel base, 30, one shutter 40 and a pull bar 50; This is gone into son 20 and is provided with a flexible member; In this embodiment, this flexible member is a spring 21, and this pull bar 50 is provided with a spring 51.This is gone into son and 20 is arranged in the male model plate 300, and the one of which end may extend into the inclined hole of the die cavity of this mould with this product 10 of moulding, and the other end is a stress surface, and in this embodiment, this stress surface of going into son 20 is a sphere.This shovel base 30 is positioned at the below that this goes into son 20; The one of which end is fixed on this male model fagging 400, and the other end is a force surface, in this embodiment; This force surface is an inclined-plane; The force surface of this shovel base 30 contacts with this stress surface of going into son 20 when matched moulds, and preferably, this goes into the inclined-plane of son 20 perpendicular to this this shovel base 30.In another embodiment, this stress surface of going into son 20 can be an inclined-plane, and the force surface of this shovel base 30 is a sphere.One end of this shutter 40 is located on this caster 200, and the other end is located on this male model plate 300.The lower end of this pull bar 50 is fixedly arranged on this male model fagging 400, and its main body is passed this male model plate 300, and can be up and down in male model plate 300, and the upper end of this pull bar 50 has one spacing 52, is used for when die sinking, position-limiting action being played in the motion of male model fagging 400.
This goes into the effect of replacing that son 20 receives the inclined-plane of this shovel base 30 during matched moulds, the inclined hole of this product 10 of moulding, and this moment, this spring 21 was compacted, and the spring 51 of this pull bar 50 is compacted.
Please with reference to Fig. 2, during die sinking for the first time, this male model plate 300 moves downward, and can't separate owing to the effect of this shutter 40 between this caster 200 and this male model plate 300.This male model fagging 400 is owing to the elastic force effect that receives these pull bar 50 upper springs 51 moves downward, and this shovel base 30 moves downward with this male model fagging 400 together, thereby this is gone into son 20 and under these spring 21 effects, moves downward and withdraw from the inclined hole that die cavity withdraws from this product 10.After this male model fagging 400 moves downward a segment distance; Meet this male model plate 300 for spacing 52 of this pull bar 50; Therefore this pull bar 50 is held this male model fagging 400; Thereby make this male model fagging 400 can't continue to move downward, this moment should shovel base 30 still replace this and go into sub 20 sphere stress surface, so this is gone into sub 20 and can not come off to carry out moulding next time.
Please with reference to Fig. 3, during die sinking for the second time, this shutter 40 is opened, and this male model plate 300 continues to move downward, and opens in 200 minutes with this caster.After this caster 200 was opened a segment distance in 300 minutes with this male model plate,, mould ejects this product 10 thereby getting into the follow-up product stripping process of ejecting.
The present invention is through increasing a male model fagging 400; Cooperate this to go into son 20 through the shovel base on this male model fagging 400 30 coupling mechanism force is provided; This spring 21 of going on the son 20 provides the power of loosing core; Go into son 20 in the moment of die sinking and break away from this product 10 back-offs part earlier, continue die sinking then and eject product 10 along oblique extraction.Adopt that this oblique core-pulling mechanism is simple in structure, the demoulding is stable and cost is low, is suitable for producing the product that all kinds of inclined hole central axis and mold center's line have the angle of inclination.
Be pointed out that, the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any professional and technical personnel of being familiar with does the foregoing description based on technical scheme of the present invention all fall in protection scope of the present invention.
