Description

The ejecting structure of mould
[technical field]
The present invention relates to a kind of ejecting structure, particularly relate to a kind of ejecting structure of mould.
[background technology]
All can there is barb in many plastic cement products, use mould carry out shaping in just need to design corresponding structure it 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, second barb 12 and the 3rd barb 13.
Please jointly consult Fig. 2, Fig. 3, it illustrates a kind of mould first sectional structure chart, second sectional structure chart of prior art respectively.As shown in the figure, inner slide 201, outer slide 204, taper pin 206 are respectively in order to shaping described first barb 11, second barb 12 and the 3rd barb 13.
This mould has bottom plate 20, male template 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, also has upper plate 28 and lower roof plate 29 between described slide block swinging plate 23 and described master mold board 25.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 first Angle Pin 203 is fixed on described slide block swinging plate 23.This mould also has outer slide 204, second Angle Pin 205, and described outer slide 204 is located in the die between described male template 21 and caster 22, and described second Angle Pin 205 is fixed on described male template 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 template 21 is located in its one end, the other end is located at described caster 22.
During die sinking, due to the effect of described shutter 210, carry out first time die sinking, first time die sinking is between described caster 22 and described slide block swinging plate 23, and at the end of first time die sinking, described inner slide 201 exits described first barb 11; After the movable end of described pull bar 208 and described stopper slot 209 are interfered, carry out second time die sinking, second time die sinking is between described male template 21 and caster 22, and at the end of second time die sinking, described outer slide 204 exits described 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 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 pours in down a chimney mould, when ejecting described upper plate 28 and lower roof plate 29, usually adopt as Fig. 4 oil hydraulic cylinder 211, in order to avoid upper plate 28 described during first time die sinking and lower roof plate 29 die sinking together, taper pin 206 is caused to draw bad product 10; Need control first time die sinking time described upper plate 28 and lower roof plate 29 motionless, return pin 212 increases return pin block 213, when first time die sinking 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 fixed on master mold board 25 and lower roof plate 29, during first time die sinking, oil hydraulic cylinder 211 needs and first time die sinking is 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 bradykinetic, first time, Resistance of opening mould was excessive cannot die sinking.At the end of first time die sinking, oil hydraulic cylinder 211 also needs same EOS, moves again, control too complicated, wayward, unstable when ejecting after second time die sinking completes, and oil hydraulic cylinder 211 stroke is that opening stroke adds ejection stroke for the first time, and stroke is too large.
In view of this, be necessary the ejecting structure developing a kind of mould in fact, uppity problem complicated, unstable with the ejecting structure solving prior art mould.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of ejecting structure of mould, solve the ejecting structure complexity of prior art mould, unstable, uppity problem.
In order to achieve the above object, the invention provides the ejecting structure of mould, this mould has bottom plate, male template, caster, slide block swinging plate, cushion block, master mold board, hot runner manifold and the upper mounted plate sequentially set up, also have upper plate and lower roof plate between described slide block swinging plate and described master mold board, this ejecting structure comprises:
Return pin, its one end is fixed between described upper plate and described lower roof plate, and described return pin is arranged in described caster and described slide block swinging plate;
Return pin block, it is fixed on described return pin one end away from described upper plate, and when matched moulds, described return pin block is held in described male template;
Limited block, it is fixed on the side of described male template, is provided with spacing fluting in described limited block;
Spacer pin, its one end be fixed on described return pin block side, the other end is movable is located in described spacing fluting.
Optionally, described ejecting structure also has spring, and described spring housing is located on described return pin.
Optionally, this mould also has inner slide, shovel base and the first Angle Pin, and described inner slide is located in described caster, and described shovel base is fixed on described slide block swinging plate, and described first Angle Pin is fixed on described slide block swinging plate.
Optionally, this mould also has outer slide, the second Angle Pin, and described outer slide is located in the die between described male template and caster, and described second Angle Pin is fixed on described male template.
Optionally, this mould also has taper pin, oblique pin base, and described oblique pin base is fixed on described upper plate, and described oblique pin base is fixed in described taper pin one end, the other end is arranged in described slide block swinging plate, caster until die.
Optionally, this mould also has pull bar and stopper slot, and described stopper slot is located in described caster, and described slide block swinging plate is fixed in described pull bar one end, the other end is located in described stopper slot.
Optionally, this mould also has shutter, and described male template is located in its one end, the other end is located at described caster.
Compared to prior art, utilize ejecting structure of the present invention, during die sinking, during first time die sinking, slide block swinging plate leaves caster, and upper lower roof plate keeps motionless by return pin and return pin block and caster, thus the safety of guarantee product; It is second time die sinking after first time die sinking terminates, namely the die sinking between male and female template, product stays master mold side by taper pin, after the stroke of spacing fluting is covered in second time die sinking, limited block can drive spacer pin die sinking together, because spacer pin is fixed on return pin block, upper and lower top board ejecting product can be driven, until ejection stroke is covered, product is ejected completely, takes out product.Visible, this structure can not use oil hydraulic cylinder, and structure is simple, stablize, be easy to control.
