Abstract
A kind of two-part taper pin, it is applied in mould, and this two-part taper pin includes: oblique pin base, and it is located in the upper ejector plate of above-mentioned mould；First paragraph taper pin, its one end is located on above-mentioned oblique pin base, and this first paragraph taper pin other end is provided with groove；Second segment taper pin, it is located on above-mentioned first paragraph taper pin, and this second segment taper pin is provided with fixing pin, and this fixing pin one end is located in above-mentioned groove.The two-part taper pin of the present invention, when producing the product having back-off at overhead kick on taper pin exit axis, first paragraph taper pin banking motion exits the overhead kick of product, and second segment taper pin moves vertically, and makes this two-part taper pin successfully exit, completes stripping action.
Description
[technical field]
The present invention relates to a kind of taper pin, be specifically related to a kind of two-part taper pin.
[background technology]
When producing plastic cement products, on plastic cement products, the overhead kick of inner side and the less overhead kick of body, typically use
Taper pin exits, and exiting product overhead kick when, taper pin also has effect of ejecting product, and therefore taper pin is being moulded
It is widely used on sealing rubber die.
But, when producing plastic cement products, sometimes because of the restriction of plastic cement products structure, cause at product overhead kick
Producing back-off on taper pin exit axis, refer to shown in Fig. 1, it illustrates has back-off on taper pin exit axis
The schematic diagram of product.Because product 10 is provided with back-off 12 at overhead kick 11 on taper pin exit axis, taper pin cannot
Exit, product cannot 10 demouldings, cause the puzzlement of Design of Dies.
In view of this, it is necessary to develop a kind of novel two-part taper pin in fact, exits producing taper pin at overhead kick
When having the product of back-off on direction, this two-part taper pin can successfully exit, and makes product stripping.
[summary of the invention]
Therefore, it is an object of the invention to provide a kind of two-part taper pin, this two-part taper pin is producing at overhead kick
When having the product of back-off on taper pin exit axis, it is possible to successfully exit, make product stripping.
In order to achieve the above object, the two-part taper pin of the present invention, it is applied in mould, and this two-part is oblique
Pin includes:
Oblique pin base, it is located in the upper ejector plate of above-mentioned mould；
First paragraph taper pin, its one end is located on above-mentioned oblique pin base, and this first paragraph taper pin other end is provided with groove；
Second segment taper pin, it is located on above-mentioned first paragraph taper pin, and this second segment taper pin is provided with fixing pin, and should
Fixing pin one end is located in above-mentioned groove.
Especially, above-mentioned second segment taper pin also includes copper plug.
Especially, above-mentioned groove is dovetail groove.
Compared to prior art, the two-part taper pin of the present invention, have on taper pin exit axis at overhead kick producing
During the product of back-off, first paragraph taper pin banking motion exits the overhead kick of product, and second segment taper pin moves vertically,
Make this two-part taper pin successfully exit, complete stripping action.
[accompanying drawing explanation]
Fig. 1 illustrates the schematic diagram of the product having back-off on taper pin exit axis.
Fig. 2 illustrates the schematic diagram of two-part taper pin matched moulds state of the present invention.
Fig. 3 illustrates the schematic diagram of two-part taper pin die opening state of the present invention.
[detailed description of the invention]
Referring to shown in Fig. 2, it illustrates the schematic diagram of two-part taper pin matched moulds state of the present invention.The present invention's
Two-part taper pin, it is applied in mould, and this two-part taper pin includes:
Oblique pin base 400, it is located in the upper ejector plate 40 of above-mentioned mould；
First paragraph taper pin 300, its one end is located on above-mentioned oblique pin base 400, and the other end is provided with groove 310, in
In the present embodiment, this groove 310 is dovetail groove；
Second segment taper pin 200, it is located on above-mentioned first paragraph taper pin 300, and this second segment taper pin 200 is only provided with
Position pin 210, this fixing pin 210 one end is located in above-mentioned groove 310, and when mould matched moulds state, should be stopped
Position pin 210 contacts with above-mentioned groove 310 one side, and this second segment taper pin 200 also includes copper plug 220, should
Copper plug 220 is used for stopping above-mentioned fixing pin 200.
Referring to shown in Fig. 3, it illustrates the schematic diagram of two-part taper pin die opening state of the present invention.Mould die sinking
Time, male template 30 separates with caster 20, and the ejecting mechanism of mould moves upward, and upper ejector plate 40 is upwards
Motion, the oblique pin base 400 being fixed in this upper ejector plate 40 drives this first paragraph taper pin 300 to move together,
Owing to first paragraph taper pin 300 has gradient, it moves along first paragraph taper pin 300 gradient direction, and (first paragraph is oblique
Direction shown in arrow at pin), this first paragraph taper pin 300 is while moving upward, and rearward movement exits product
The overhead kick 11 of product 10, the fixing pin 210 in second segment taper pin 200 is movable in above-mentioned groove 310 simultaneously,
Make second segment taper pin 200 upward vertical movement (direction shown in arrow at second segment taper pin), make product with this
10 demouldings, and make back-off 12 demoulding of product 10, complete stripping action.
