Abstract

The invention discloses a kind of electronic die ejector pins, comprising: penetrate tip bar and penetrate tip bar pedestal, it is described penetrate tip bar pedestal and be mounted on described penetrate tip bar bottom end;The tip bar top of penetrating is equipped with a bearing, is fixedly installed with round boss on the bearing;The tip bar of penetrating is made of upper and lower two parts, tip bar bottom surface is penetrated described in upper part, and motor is installed, oblique helical gear is installed on the motor bar of the motor bottom, tip bar upper surface is penetrated described in lower part offers threaded hole, the motor bar of the motor protrudes into the threaded hole, and the threaded bores are equipped with rib.By the above-mentioned means, a kind of electronic die ejector pin of the present invention, the die ejector pin are demoulded by the way of electronic, allow and reduce impact force when operation, protects product surface.

Description

A kind of electronic die ejector pin
Technical field
The present invention relates to mould applications, and in particular to a kind of electronic die ejector pin.
Background technique
Die ejector pin is for molding product in ejection die, and traditional mold die ejector pin is by cylindrical thimble Bar is constituted with the cylindrical thimble countersunk head of cylindrical, top shank one, which is located at cylindrical, top shank One end, and cylindrical thimble is the equal cylindrical body of an outer diameter, the die ejector pin of this structure installs mold top in a mold In needle guide hole, when needing to eject moulded products, the thimble rod of mold die ejector pin is stretched out out of pilot hole, by moulded products Ejection, therefore the die ejector pin of this structure has the following defects, whole thimble rod is in contact with guiding internal surface of hole, in thimble When bar moves back and forth, rubs with guiding internal surface of hole, grind and spend so as to cause thimble rod outer surface, 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, needs to be ejected molding product with biggish thrust, inconvenient for use.
Summary of the invention
It is simpler when can thimble be worked the invention mainly solves the technical problem of providing a kind of electronic die ejector pin Folk prescription is just.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of electronic die ejector pin, comprising: Penetrate tip bar and penetrate tip bar pedestal, it is described penetrate tip bar pedestal and be mounted on described penetrate tip bar bottom end;
The tip bar top of penetrating is equipped with a bearing, is fixedly installed with round boss on the bearing;
The tip bar of penetrating is made of upper and lower two parts, and tip bar bottom surface is penetrated described in upper part and is equipped with motor, the motor bottom Oblique helical gear is installed on the motor bar in portion, tip bar upper surface is penetrated described in lower part and offers threaded hole, the electricity of the motor Machine bar protrudes into the threaded hole, and the threaded bores are equipped with rib.
In a preferred embodiment of the present invention, the oblique helical gear and the corresponding threaded holes close.
In a preferred embodiment of the present invention, the internal diameter of the rib is less than the outer diameter of the oblique helical gear.
The beneficial effects of the present invention are: a kind of electronic die ejector pin of the present invention, the die ejector pin by the way of electronic into Row demoulding, allows and reduces impact force when operation, protects product surface.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of electronic die ejector pin of the present invention.
The components in the drawings are labeled as follows: 1, penetrating tip bar;2, tip bar pedestal is penetrated;3, round boss;4, bearing;5, electric Machine;6, oblique helical gear;7, threaded hole;8, rib.
Specific embodiment
Referring to Fig. 1, the embodiment of the present invention includes: a kind of electronic die ejector pin, comprising: penetrate tip bar 1 and penetrate tip bar pedestal 2, it is described penetrate tip bar pedestal 2 and be mounted on described penetrate 1 bottom end of tip bar.
1 top of tip bar of penetrating is equipped with a bearing 4, and round boss 3, the bearing 4 are fixedly installed on the bearing 4 It rubs so that the round boss 3 is reduced between upper mold when rising, reduces the loss of the round boss 3.
The tip bar 1 of penetrating is made of upper and lower two parts, and 1 bottom surface of tip bar is penetrated described in upper part and is equipped with motor 5, the motor Oblique helical gear 6 is installed on the motor bar of 5 bottoms, 1 upper surface of tip bar is penetrated described in lower part and offers threaded hole 7, it is described oblique Helical gear 6 is matched with the threaded hole 7, is allowed and is penetrated tip bar 1 described in part and slide up and down, to play demoulding Movement.
The motor bar of the motor 5 protrudes into the threaded hole 7, and 7 mouthfuls of the threaded hole are equipped with rib 8, the rib 8 Internal diameter is less than the outer diameter of the oblique helical gear 6, and the rib 8 prevents the oblique helical gear 6 to be detached from the threaded hole 7.
Compared with prior art, a kind of electronic die ejector pin of the present invention, the die ejector pin are taken off by the way of electronic Mould allows and reduces impact force when operation, protects product surface.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills Art field, is included within the scope of the present invention.
