Description

The ejecting structure of mould
[technical field]
The utility model relates to a kind of ejecting structure, particularly relates to a kind of ejecting structure of mould.
[background technology]
On many plastic cement products, all can there is barb, in using mould to carry out moulding, just need to design corresponding structure it is exited.Refer to Fig. 1, Fig. 1 illustrates the structural representation into a kind of product.As shown in the figure, described product 10 has the first barb 11, the second barb 12 and the 3rd barb 13.
Please jointly consult Fig. 2, Fig. 3, it illustrates respectively a kind of mould the first sectional structure chart, second sectional structure chart of prior art.As shown in the figure, inner slide 201, outer slide 204, taper pin 206 are respectively in order to the first barb 11, the second barb 12 and the 3rd barb 13 described in moulding.
This mould has bottom plate 20, male model plate 21, caster 22, slide block swinging plate 23, cushion block 24, master mold board 25, hot runner manifold 26 and the upper mounted plate 27 sequentially set up, between described slide block swinging plate 23 and described master mold board 25, also has upper plate 28 and lower roof plate 29.This mould also has inner slide 201, shovel base 202 and the first Angle Pin 203, and described inner slide 201 is located in described caster 22, and described shovel base 202 is fixed on described slide block swinging plate 23, and described the first Angle Pin 203 is fixed on described slide block swinging plate 23.This mould also has outer slide 204, the second Angle Pin 205, and described outer slide 204 is located in the die between described male model plate 21 and caster 22, and described the second Angle Pin 205 is fixed on described male model plate 21.This mould also has taper pin 206, oblique pin base 207, and described oblique pin base 207 is fixed on described upper plate 28, and described oblique pin base 207 is fixed in described taper pin 206 one end, the other end is arranged in described slide block swinging plate 23, caster 22 until die.This mould also has pull bar 208 and stopper slot 209, and described stopper slot 209 is located in described caster 22, and described slide block swinging plate 23 is fixed in described pull bar 208 one end, the other end is located in described stopper slot 209.This mould also has shutter 210, and described male model plate 21 is located in its one end, the other end is located at described caster 22.
When die sinking, due to the effect of described shutter 210, carry out die sinking for the first time, die sinking is for the first time between described caster 22 and described slide block swinging plate 23, when die sinking finishes for the first time described in inner slide 201 exit described the first barb 11; After the movable end of described pull bar 208 and described stopper slot 209 are interfered, carry out die sinking for the second time, die sinking is for the second time between described male model plate 21 and caster 22, when die sinking finishes for the second time described in outer slide 204 exit described the second barb 12; Described upper plate 28 and lower roof plate 29 eject described taper pin 207 afterwards, until described taper pin 206 exits described the 3rd barb 13.
Refer to Fig. 4, Fig. 4 illustrates a kind of ejecting structure schematic diagram into prior art.From the above, because this mould is to pour in down a chimney mould, in the time that described upper plate 28 and lower roof plate 29 are ejected, conventionally adopt as Fig. 4 oil hydraulic cylinder 211, described in during for fear of die sinking for the first time, upper plate 28 and lower roof plate 29 die sinking together, cause taper pin 206 to draw bad product 10; Described in need to control die sinking for the first time time, upper plate 28 and lower roof plate 29 are motionless, increase return pin block 213 on return pin 212, in the time of die sinking for the first time return pin block 213 hold return pin 212 ensure described upper plate 28 and lower roof plate 29 motionless.
But, because described oil hydraulic cylinder 211 is to be fixed on master mold board 25 and lower roof plate 29, when die sinking for the first time, oil hydraulic cylinder 211 needs and die sinking is for the first time synchronized with the movement, oil hydraulic cylinder 211 moves too fast, and upper plate 28 and lower roof plate 29 can be driven, and product 10 can be damaged, oil hydraulic cylinder 211 bradykinetics, Resistance of opening mould is excessive for the first time cannot die sinking.When die sinking finishes for the first time, oil hydraulic cylinder 211 also needs same EOS, while ejecting, moves after die sinking for the second time completes again, and controls too complicatedly, wayward, unstable, and oil hydraulic cylinder 211 strokes add ejection stroke for opening stroke for the first time, and stroke is too large.
In view of this, be necessary to develop in fact a kind of ejecting structure of mould, to solve the ejecting structure complexity of prior art mould, unstable, uppity problem.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of ejecting structure of mould, solves ejecting structure complexity, unstable, the uppity problem of prior art mould.
In order to achieve the above object, the utility model provides the ejecting structure of mould, this mould has bottom plate, male model plate, caster, slide block swinging plate, cushion block, master mold board, hot runner manifold and the upper mounted plate sequentially set up, between described slide block swinging plate and described master mold board, also have upper plate and lower roof plate, this ejecting structure comprises:
