Description
Technical field
The present invention relates to plastic mould technical fields, and in particular to a kind of preceding mould back-off core-pulling mechanism.
Background technique
Demand according to product function, it is often necessary to which product is set in the buckle that master mold side (into glue side) designs a fluking type
Meter.This product structure will form the barb for preventing product from deviating from plastic mould, difficult in the extreme to realize molding, if adopted
With some conventional abjection mechanisms, also the size of mold can be made very big, and structure is complicated, to the manufacturing band of mold
Carry out more difficulties, increases the manufacturing cost of mold, increase mould volume and weight.
Summary of the invention
In view of the above drawbacks of the prior art, technical purpose of the invention be to provide a kind of structure is simple, be easy to plus
Work manufacture, the preceding mould that product stripping is easy, mould volume is small, light-weight, die manufacturing cost is low are buckled to core-pulling mechanism.
To realize the above-mentioned technical purpose, technical solution provided by the invention is as follows:
A kind of preceding mould of the invention is buckled to core-pulling mechanism, core pulling component and bullet including product buckle barb position is arranged in
Spring, core pulling component be reciprocatingly set to solid plate, mode corresponding product snapped-in position slideway in；The product buckle is high
Degree is less than or equal to the moving distance of core pulling component；Core pulling component one end is forming surface, the setting of forming surface tip edge position
There is the groove matched with product buckle barb, spring, the spring are set between the core pulling component other end and solid plate
Decrement be greater than core pulling component moving distance.
Above-mentioned core pulling component includes oblique top and pedestal, be arranged between the oblique top and pedestal screw connect, be threadedly coupled or
Integral type connection.
Above-mentioned slideway includes interconnected straight trough and skewed slot, and the pedestal is set in straight trough, the depth of the straight trough
Greater than the thickness of pedestal, the oblique top is placed in skewed slot.
The position setting spring base of core pulling component is corresponded on above-mentioned solid plate, the spring-compressed is placed in spring base, institute
State one end connection pedestal of spring.
The section of above-mentioned oblique top is circle.
The outer end face of above-mentioned oblique top is forming surface, and the horizontal plane of the groove is placed on the extended line of oblique top forming surface, institute
The inclined-plane for stating groove intersects at the arc surface of oblique top.
Beneficial effects of the present invention:
It includes pedestal and the core pulling component that oblique top is constituted, base end that the present invention, which installs one in product card button hook inversion,
One compressed spring is installed, spring will push core pulling component and eject along gradient direction when mold die sinking, such core pulling component
The barb that product can be detached from well on buckle.Its structure is simple, and demoulding is stablized, easy to manufacture, and mold
It is small in size, light-weight, greatly reduce the manufacturing cost of mold.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is mold structure diagram of the invention.
Specific embodiment
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
Embodiment:
Referring to Figures 1 and 2, the present invention includes core pulling component and spring 4.
Core pulling component includes oblique top 1 and pedestal 2, and the section of oblique top 1 is circle, and screw 3 is arranged between oblique top 1 and pedestal 2
It links together.
The corresponding product that core pulling component is set to the mode 6 of solid plate 5 with being reciprocally moveable buckles in the slideway 8 of 7 positions,
The moving distance of the core pulling component is more than or equal to the height of product buckle.
Slideway 8 includes interconnected straight trough and skewed slot, and pedestal 2 is set in straight trough, and the depth of straight trough is greater than pedestal 2
Thickness moves pedestal 2 in straight trough, and oblique top 1 is placed in skewed slot.
The outer end face of oblique top 1 is forming surface, and the setting of forming surface tip edge position matches recessed with 7 overhead structures of buckle
Slot 8, the horizontal plane of groove 8 are placed on the extended line of 1 forming surface of oblique top, and the inclined-plane of groove 8 intersects at the arc surface of oblique top 1.
The position setting spring base 9 of core pulling component is corresponded on solid plate 5, the compression of spring 4 is placed in spring base 9, spring 4
One end connection core pulling component in pedestal 2, the decrement of spring 4 is greater than the moving distance of the core pulling component.
As a further improvement, threaded connection or integral type connection also can be set between oblique top 1 and pedestal 2.
A core pulling component is arranged in product buckle barb position in the present invention, and core pulling component includes using screw 3 by 1 He of oblique top
Pedestal 2 links together.One compressed spring is installed between pedestal 2 and solid plate 5.When mold die sinking, spring 4 will push core pulling
Component is ejected along gradient direction, and such core pulling component can be detached from the back-off on buckle 7 well.When mold clamping,
Core pulling component can then be pushed back correct position by the dynamic model of mold.It is fundamentally solved using the present invention and forms this back-off
Problem.
The configuration of the present invention is simple, demoulding is stablized, easy to manufacture, and mould volume is small, light-weight, greatly reduces
The manufacturing cost of mold.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
