Abstract
The invention discloses a kind of die ejector pin of adjustable dimension, including：One penetrates tip bar base, and the tip bar base of penetrating offers some chutes for circle, described penetrate on tip bar base, some chutes by it is described penetrate the tip bar base center of circle centered on array distribution, the chute mouth is symmetrically provided with rib, with scale on the rib；It is some to penetrate tip bar, some tip bars of penetrating are in the chute, described penetrate at the top of tip bar is provided with circular arc chamfering, the tip bar bottom of penetrating is provided with round slider, slide bar is installed on the sliding block, the slide bar runs through the chute, and the slide bar is provided with locking system with the tip bar base outer wall junction of penetrating.By the above-mentioned means, a kind of die ejector pin of adjustable dimension of the present invention, the die ejector pin can considerably increase the wide usage of the die ejector pin with sized to adapt to various sizes of pilot hole.
Description
Technical field
The present invention relates to mould applications, and in particular to a kind of die ejector pin of adjustable dimension.
Background technology
Die ejector pin is the product for being molded in ejection die, and traditional mould die ejector pin is by cylindrical thimble
Bar, formed with the cylindrical thimble countersunk head of cylindrical, top shank one, the cylindrical thimble countersunk head is located at cylindrical, top shank
One end, and cylindrical thimble is the equal cylinder of an external diameter, the die ejector pin of this structure installs mould top in a mold
In needle guide hole, when needing to eject moulded products, the thimble rod of die ejector pin stretches out out of pilot hole, by moulded products top
Go out, the size of traditional thimble will be according to the size selection of pilot hole, one-to-one pairing.
The content of the invention
The present invention solves the technical problem of a kind of die ejector pin of adjustable dimension is provided, the chi of thimble can be adjusted
It is very little.
In order to solve the above technical problems, one aspect of the present invention is：A kind of mould top of adjustable dimension
Pin, including：
One penetrates tip bar base, and the tip bar base of penetrating offers some chutes for circle, described penetrate on tip bar base, some described
Chute by it is described penetrate the tip bar base center of circle centered on array distribution, the chute mouth is symmetrically provided with rib, on the rib
With scale；
Some to penetrate tip bar, for some tip bars of penetrating in the chute, described penetrate at the top of tip bar is provided with circular arc chamfering, institute
State and penetrate the tip bar bottom round slider is installed, slide bar is installed, the slide bar runs through the chute, the slide bar on the sliding block
Locking system is installed with the tip bar base outer wall junction of penetrating.
It is in a preferred embodiment of the present invention, described that to penetrate tip bar quantity identical with the chute quantity.
In a preferred embodiment of the present invention, the distance between two described ribs of each chute mouth are less than described
The diameter of sliding block.
The beneficial effects of the invention are as follows：A kind of die ejector pin of adjustable dimension of the present invention, the die ejector pin can be adjusted
Size considerably increases the wide usage of the die ejector pin to adapt to various sizes of pilot hole.
Brief description of the drawings
Fig. 1 is a kind of front view of the die ejector pin of adjustable dimension of the present invention.
Fig. 2 is a kind of top view of the die ejector pin of adjustable dimension of the present invention.
The mark of each part is as follows in accompanying drawing：1st, tip bar base is penetrated；2nd, chute；3rd, tip bar is penetrated；4th, rib；5th, sliding block；6、
Slide bar；7th, locking system.
Embodiment
Fig. 1 and Fig. 2 are referred to, the embodiment of the present invention includes：A kind of die ejector pin of adjustable dimension, including：
One penetrates tip bar base 1, and for the tip bar base 1 of penetrating for circle, described penetrate on tip bar base 1 offers some chutes 2, some
The chute 2 by it is described penetrate the center of circle of tip bar base 1 centered on array distribution, the chute 2, which is used to installing, described penetrates tip bar 3.
2 mouthfuls of the chute is symmetrical to be provided with rib 4, with scale on the rib 4 so that penetrating tip bar described in regulation
The size for the thimble that the position is formed is known that when 3.
Some to penetrate tip bar 3, for some tip bars 3 of penetrating in the chute 2, the top of tip bar 3 of penetrating is provided with circular arc
Shape chamfering, the quantity of tip bar 3 of penetrating is identical with the quantity of chute 2, and the slip in the chute 2 of tip bar 3 is penetrated by described, from
And adjust the size of the thimble.
The bottom of tip bar 3 of penetrating is provided with round slider 5, the distance between two described ribs 4 of each 2 mouthfuls of chute
Less than the diameter of the sliding block 5, prevent the sliding block 5 from departing from the chute 2.
Slide bar 6 is installed, the slide bar 6 runs through the chute 2, and the slide bar 6 is used to adjust each institute on the sliding block 5
The position of sliding block 5 is stated, so as to adjust the position for penetrating tip bar 3.
The slide bar 6 is provided with locking system 7 with the outer wall junction of tip bar base 1 of penetrating, and the locking system 7 is used for
Positioned to penetrating tip bar 3 described in regulating.
Compared with prior art, a kind of die ejector pin of adjustable dimension of the present invention, the die ejector pin can be with sized
To adapt to various sizes of pilot hole, the wide usage of the die ejector pin is considerably increased.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
