Description
[technical field]
The utility model relates to a kind of inclined pin structure, particularly relates to a kind of large-angle inclined latch structure of mould.
[background technology]
Round pin roller Slanting pin mechanism is a kind of inclined pin structure that generally uses.See also Fig. 1, Fig. 1 illustrates the round pin roller inclined pin structure into prior art.This structure promotes lower liftout plate 101 by push rod 100 and upper ejector plate 102 moves upward; Fixed plate 102 is provided with oblique pin base 103, is provided with chute 104 in described oblique pin base 103, and taper pin 105 bottoms are provided with round pin 106, and described round pin 106 slidingtypes are located in described chute 104; Described upper ejector plate 102 moves upward, and described round pin 106 is pushed corresponding upwards and to left movement in described chute 104, and then described taper pin 105 has one to the component of left movement, to reach the purpose that withdraws from product 107 barbs 108.
Be a thrust to be divided into the thrust (being equivalent to distortion power) of both direction but shortcoming is this type of inclined pin structure, so gradient value maximum is got 12 degree usually, surpass oblique 105 pins of 12 degree easily stuck.When product 107 barbs 108 distances during greater than 20mm, when the ejection stroke of mould will be enlarged to ejection stroke greater than the 100mm(vertical direction and is 100mm, get maximum angle 12 degree, its corresponding horizontal direction stroke is 21.26mm, consider safe clearance 2mm, barb that only can corresponding 19.26mm), thus the mould overall height will increase, required board tonnage also will strengthen, and has increased die cost.
In view of this, be necessary to develop in fact a kind of large-angle inclined latch structure of mould, to address the above problem.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of large-angle inclined latch structure of mould, and when larger with the product barb distance that solves moulding, the maximum angle of taper pin is too little, and the ejection stroke of taper pin is too large, the problem that die cost is too high.
In order to achieve the above object, the large-angle inclined latch structure of the mould that the utility model provides, moulding has the product of barb, described mould has male model plate, cushion block and the bottom plate that sequentially is provided with, has male die core in described male model plate, sequentially be provided with upper ejector plate and lower liftout plate between described male model plate and described bottom plate, be provided with the push rod that passes described bottom plate below described lower liftout plate, this inclined pin structure comprises:
Oblique pin base, it is located in described upper ejector plate, and described oblique pin base one side is provided with the gathering sill that gradient is the first inclination angle, and described oblique pin base has activity space in the horizontal direction;
Taper pin, the one end is fixed in described oblique pin base, and the other end has the forming part of the barb of the described product of moulding, and movable the wearing of described taper pin penetrated in described male model plate and described male die core, and the gradient of described taper pin is also described the first inclination angle;
Guide pad, one end are fixed in described male model plate, and the other end has the guide rail that coordinates with described gathering sill, and the gradient of described guide rail is also described the first inclination angle.
Optionally, described the first inclination angle is greater than 12 degree.
Optionally, described gathering sill is T-shaped, and described guide rail is T-shaped.
Optionally, described gathering sill is dovetail groove, and described guide rail is dove-tail form.
Compared to prior art, utilize the large-angle inclined latch structure of mould of the present utility model, when die sinking, described push rod upwards ejects, make described upper ejector plate and described lower liftout plate move upward, the gathering sill of described oblique pin base is forced to move in the horizontal direction under the guide rail effect of described guide pad, also take exercises in the horizontal direction thereby described oblique pin base drives described taper pin, and then the forming part of described taper pin can withdraw from the barb of described product.Because described taper pin and described oblique pin base are fixing, and described oblique pin base is to move by the direct acting thrust of described guide pad and described gathering sill, therefore belong to simple thrust but not distortion power indirectly, so described the first inclination angle can be wide-angle, and then described ejection stroke can diminish, mold height can reduce, and die cost can correspondingly reduce.

[specific embodiment]
Please jointly consult Fig. 2-Fig. 4, Fig. 2 illustrates matched moulds status architecture schematic diagram, Fig. 3 for large-angle inclined latch structure first embodiment of mould of the present utility model and illustrates and illustrate die opening state structural representation into large-angle inclined latch structure first embodiment of mould of the present utility model to cut-away structure chart, Fig. 4 for the A-A of Fig. 2.
In order to achieve the above object, the large-angle inclined latch structure of the mould that the utility model provides, moulding has the product 201 of barb 200, described mould has male model plate 202, cushion block 203 and the bottom plate 204 that sequentially is provided with, has male die core 205 in described male model plate 202, sequentially be provided with upper ejector plate 206 and lower liftout plate 207 between described male model plate 202 and described bottom plate 204, described lower liftout plate 207 belows are provided with the push rod 208 that passes described bottom plate 204, in this first embodiment, this inclined pin structure comprises:
Wherein, described the first inclination angle can be for spending greater than 12.
When die sinking, described push rod 208 upwards ejects, make described upper ejector plate 206 and described lower liftout plate 207 move upward, the gathering sill of described oblique pin base 209 is forced to move in the horizontal direction under the guide rail effect of described guide pad 213, thereby described oblique pin base 209 drives described taper pin 211 and also takes exercises in the horizontal direction, and then the forming part 212 of described taper pin 211 can withdraw from the barb 200 of described product 201.
Compared to prior art, utilize the large-angle inclined latch structure of mould of the present utility model, because described taper pin 211 is fixing with described oblique pin base 209, and described oblique pin base 209 is to move by described guide pad 213 and the direct acting thrust of described gathering sill, therefore belong to simple thrust but not distortion power indirectly, so described the first inclination angle can be not stuck for wide-angle, and then described ejection stroke can diminish, mold height can reduce, and die cost can correspondingly reduce.
Please consult Fig. 5-Fig. 7, Fig. 5 illustrates matched moulds status architecture schematic diagram, Fig. 6 for large-angle inclined latch structure second embodiment of mould of the present utility model and illustrates and illustrate die opening state structural representation into large-angle inclined latch structure second embodiment of mould of the present utility model to cut-away structure chart, Fig. 7 for the B-B of Fig. 5 again.
This second embodiment and the first embodiment difference place are, are located at the gathering sill of described oblique pin base 209 1 sides, are dovetail groove 216 herein; The guide rail that described guide pad 213 coordinates with described dovetail groove 216 is dove-tail form guide rail 215.Certainly, described the second embodiment still can reach the effect that described the first embodiment reaches.
