Abstract
The utility model discloses a demoulding mechanism of automatic pressure equipment of annotating of commutator, its characterized in that: the demoulding mechanism comprises a fixed plate, a movable plate, a guide pin, long and short ejector pins and a long and short stripping sleeve, wherein the fixed plate is pushed by a demoulding cylinder to move up and down, the movable plate is connected below the fixed plate, a buffer spring is arranged between the movable plate and the movable plate, the long and short ejector pins are fixed on the fixed plate, the long stripping sleeve is fixed on the movable plate, a sleeve hole is formed in the long stripping sleeve to allow the long ejector pins to move through, and a sleeve hole is formed in the short stripping sleeve to allow the short. The utility model discloses can realize that the port of commutator pressure injection product is automatic to be removed useless, realize simultaneously pressing the substep drawing of patterns of injecting the product, solve demoulding mechanism because of the too big fragile technical problem of atress.
Description
Technical Field
The utility model relates to an automatic equipment of annotating of commutator, concretely relates to automatic demoulding mechanism who annotates equipment of pressing of commutator.
Background
The commutator is manufactured by a very important process called commutator pressure injection process, the commutator pressure injection process is to complete the combination of the commutator copper shell and the bakelite powder through the pressure injection of the bakelite powder, after commutator products are pressure injection molded, the commutator products need to be separated from a middle template of a pressure injection mold, at present, when a demolding mechanism works, all commutator pressure injection products in the middle template are simultaneously ejected, the demolding mechanism is stressed greatly and is easy to damage, meanwhile, port waste materials of the commutator pressure injection products cannot be removed, and the commutator pressure injection products can be completed only by subsequent work.
Disclosure of Invention
In view of the not enough of prior art, the to-be-solved technical problem of the utility model is to provide a port that can realize the commutator and press and annotate the product is automatic to be removed useless, realizes simultaneously pressing the substep drawing of patterns of annotating the product, avoids pressing the automatic demoulding mechanism of notes equipment because of the commutator that the atress is too big and fragile.
The utility model discloses a realize through following technical scheme:
demoulding mechanism of automatic pressure equipment of annotating of commutator, its characterized in that: the demoulding mechanism comprises a fixed plate, a movable plate, a guide pin, long and short ejector pins and a long and short stripping sleeve, wherein the fixed plate is pushed by a demoulding cylinder to move up and down, the movable plate is connected below the fixed plate, a buffer spring is arranged between the movable plate and the movable plate, the long and short ejector pins are fixed on the fixed plate, the long stripping sleeve is fixed on the movable plate, a sleeve hole is formed in the long stripping sleeve to allow the long ejector pins to move through, and a sleeve hole is formed in the short stripping sleeve to allow the short.
In a free state, the height of the tip of the short thimble is not less than the height of the lower end face of the long stripping sleeve.
According to the technical scheme, the demolding mechanism of the automatic commutator pressure injection equipment not only realizes automatic waste removal of the port of the commutator pressure injection product, but also realizes step demolding of the pressure injection product, and solves the technical problem that the demolding mechanism is easy to damage due to overlarge stress.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figures, the utility model discloses a demoulding mechanism of automatic pressure equipment of commutator, including fixed plate 41, fly leaf 43, guide pin 44, long thimble 48, short thimble 47 and long stripper sleeve 45, short stripper sleeve 46, fixed plate 41 is promoted by drawing of patterns cylinder 40 and is made the activity from top to bottom, fly leaf 43 is connected in the below of fixed plate 41, be equipped with buffer spring 42 between the two, long thimble 48, short thimble 47 are fixed in fixed plate 41, long stripper sleeve 45, short stripper sleeve 46 are fixed in fly leaf 43, long stripper sleeve 45 is equipped with the trepanning and lets long thimble 48 activity pass through, short stripper sleeve 46 is equipped with the trepanning and lets short thimble 47 activity pass through; in a free state, the height of the tip of the short thimble 47 is not lower than the height of the lower end surface of the long stripper sleeve 45.
The action process of the demoulding mechanism is as follows: the middle template B is pushed to be in place, the demolding cylinder 40 pushes the fixing plate 41 to be downward, the movable plate 43, the guide pin 44, the long ejector pin 48, the short ejector pin 47, the long stripping sleeve 45 and the short stripping sleeve 46 are downward, the guide pin 44 firstly positions the middle template B, then the long ejector pin 48 firstly contacts with a pressure injection product, injection molding waste at the port of the pressure injection product is firstly removed, then the long stripping sleeve 45 pushes the pressure injection product out of the mold cavity of the middle template B, the pressure injection product falls through a blanking hole formed in the working platform 20, then the short ejector pin 47 contacts with the pressure injection product, the injection molding waste at the port of the pressure injection product is firstly removed, and then the short stripping sleeve 46 pushes the pressure injection product out of the mold cavity of the middle template B; the action process realizes the automatic waste removal of the ports of the commutator injection products, simultaneously realizes the step-by-step demoulding of the injection products, and solves the technical problem that the demoulding mechanism is easy to damage due to overlarge stress.
Claims (2)
