Abstract
The invention discloses a kind of wear-resistant die ejector pin, including：Penetrate tip bar and penetrate tip bar base, the tip bar floor installation of penetrating penetrates tip bar bottom described；Described penetrate is provided with some needle caps on tip bar, needle cap top and the tip bar top of penetrating are equipped with circular ring-type groove, internal thread is provided with the groove, needle cap bottom is provided with external screw thread, pass through rotational lock between two adjacent needle caps, often section needle cap side wall top is provided with round edge, and the round edge is tilted down.By the above-mentioned means, a kind of wear-resistant die ejector pin of the invention, the die ejector pin is provided with some needle caps, it can throw away, using second needle cap, more economize on resources when after a needle cap abrasion.
Description
Technical field
The present invention relates to mould applications, and in particular to a kind of wear-resistant die ejector pin.
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, is constituted, the cylindrical thimble countersunk head is located at cylindrical, top shank with the cylindrical thimble countersunk head of cylindrical, top shank one
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 ejection moulded products, the thimble rod of mould die ejector pin stretches out out of pilot hole, by moulded products
Ejection, therefore there is following defect in the die ejector pin of this structure, whole thimble rod is in contact with being oriented to internal surface of hole, in thimble
When bar is moved back and forth, rubbed with being oriented to internal surface of hole, so as to cause thimble rod outer surface mill flower, become thimble outer surface
It is coarse, and make thimble rod surface wear, the service life of die ejector pin is substantially reduced, and due in thimble rod and pilot hole
The contact area on surface is big, it is necessary to could be ejected the product of shaping with larger thrust, inconvenient for use.
The content of the invention
The present invention solves the technical problem of a kind of wear-resistant die ejector pin is provided, the loss of thimble can be reduced.
In order to solve the above technical problems, one aspect of the present invention is：A kind of wear-resistant die ejector pin, bag
Include：Penetrate tip bar and penetrate tip bar base, the tip bar floor installation of penetrating penetrates tip bar bottom described；
Described penetrate is provided with some needle caps on tip bar, needle cap top and the tip bar top of penetrating are equipped with circular ring-type groove,
Internal thread is provided with the groove, needle cap bottom is provided between external screw thread, two adjacent needle caps by rotational lock,
Often section needle cap side wall top is provided with round edge, and the round edge is tilted down.
In a preferred embodiment of the present invention, the external screw thread is engaged with the internal thread.
In a preferred embodiment of the present invention, the quantity of needle cap is five.
The beneficial effects of the invention are as follows：A kind of wear-resistant die ejector pin of the present invention, the die ejector pin is provided with some needle caps,
It can throw away, using second needle cap, more economize on resources when after a needle cap abrasion.
Brief description of the drawings
Fig. 1 is a kind of front view of wear-resistant die ejector pin of the invention.
Fig. 2 is a kind of sectional view of wear-resistant die ejector pin needle cap of the invention.
The mark of each part is as follows in accompanying drawing：1st, tip bar is penetrated；2nd, tip bar base is penetrated；3rd, needle cap；4th, groove；5th, internal thread；
6th, external screw thread；7th, round edge.
Embodiment
Fig. 1 and Fig. 2 are referred to, the embodiment of the present invention includes：A kind of wear-resistant die ejector pin, including：Penetrate tip bar 1 and penetrate the tip
Bar base 2, the tip bar base 2 of penetrating penetrates the bottom of tip bar 1 installed in described.
Described penetrate is provided with some needle caps 3 on tip bar 1, can be thrown away after a needle cap 3 is worn and torn, use second
Needle cap 3, more economizes on resources, in the present embodiment, and the quantity of needle cap 3 is five.
The top of needle cap 3 and the top of tip bar 1 of penetrating are equipped with circular ring-type groove 4, and groove 4 described in circular ring-type causes institute
It is still a plane to state the top of needle cap 3, prevents the top surface of needle cap 3 from having large area depression.
Internal thread 5 is provided with the groove 4, the bottom of needle cap 3 is provided between external screw thread 6, two adjacent needle caps 3
By rotational lock, the external screw thread 6 is engaged with the internal thread 5.
Often section needle cap 3 side wall top is provided with round edge 7, and the round edge 7 is tilted down so that the thimble, which enters, to be oriented to
It is more smooth in hole.
Compared with prior art, a kind of wear-resistant die ejector pin of the invention, the die ejector pin is provided with some needle caps, when one
It can throw away, using second needle cap, more economize on resources after individual needle cap abrasion.
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
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.
