Abstract
The invention provides a spring contact core-loosing structure of a mould for a product with an inclined hole on the side, which can realize the normal demoulding of the product with the inclined hole on the side and achieve the once moulding of the product and has short production cycle. The structure comprises an upper fixed board, a female die kernel, an A board, a male die kernel, a B board, a backing board, a lower connecting board and a lower fixed board, wherein the product to be processed is arranged between the female die kernel and the male die kernel; a slant spring contact is arranged inside the male die kernel; the top of the slant spring contact sticks against the slant surface of the female die kernel; a spring of the spring contact is arranged in a slant installation slot inside the male die kernel; the bottom of the slant spring contact is arranged against the upper slant surface of a latch segment; the latch segment is tightly and fixedly connected with the backing board arranged on the lower part; a line screw successively passes through the female die kernel and the male die kernel and then is tightly fixed on the backing board; and a spring is arranged between the male die kernel and the backing board.
Description
Technical field
The present invention relates to the technical field of loosing core of mould, the bullet pin that is specially the mould of the side band inclined hole product structure of loosing core.
Background technology
Existing mould, when there was inclined hole the product side, its normally demoulding so product generally all needs secondary operations to produce inclined hole in the side, caused the process-cycle of product long, can not one-shot forming.
Summary of the invention
The bullet pin that the invention provides the mould of the side band inclined hole product structure of loosing core, it makes the normally demoulding of product of side band inclined hole, the product one-shot forming, the process-cycle is short.
The bullet pin of the mould of the side band inclined hole product structure of loosing core, it comprises upper mounted plate, mother module core, the A plate, male model benevolence, the B plate, backing plate and bottom connecting plate, bottom plate, processed product is positioned at described mother module core, between the male model benevolence, it is characterized in that: described male model benevolence inside is equipped with oblique bullet pin, the inclined-plane of described mother module core is withstood at described oblique bullet pin top, described bullet needle spring is positioned at the oblique mounting groove of described male model benevolence inside, described oblique bullet pin bottom is mounted on the ramp of latch segment, described latch segment is fastenedly connected the described backing plate of bottom, row position screw passes mother module core successively, be anchored on described backing plate, described male model benevolence after the male model benevolence, spring is housed between the backing plate.
It is further characterized in that: the two ends of described bullet needle spring are mounted on the upper surface of the bottom of the upper surface of described oblique mounting groove, oblique bullet pin respectively;
The head of described row position screw is loaded in the perforation of described mother module core, the perforation of described male model benevolence is up-small and down-big, the little penetration hole diameter in the top of described male model benevolence is less than the head diameter of described row position screw, described spring is positioned at described male model benevolence bottom large perforation, and the two ends of described spring are mounted on the large perforation upper surface, bottom of described male model benevolence, the upper surface of backing plate respectively;
Described spring housing is loaded on the middle part of described row position screw;
The perforation length of described mother module core is greater than the head thickness of described row position screw;
Described backing plate is supported on described bottom connecting plate.
After adopting structure of the present invention, during the demoulding, under the effect of spring, row position screw, male model benevolence and backing plate are finished somatotype, in this process, play pin under the elastic force effect that plays needle spring, move, break away from the inclined hole of product along the direction of loosing core, finish the demoulding of inclined hole, make the normally demoulding of product of side band inclined hole, the product one-shot forming, the process-cycle is short.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
See Fig. 1, the present invention includes upper mounted plate 1, mother module core 2, A plate 3, male model benevolence 4, B plate 5, backing plate 6 and bottom connecting plate (do not draw among the figure, belong to existing mature technology), product 9 is positioned at mother module core 2, between the male model benevolence 4, male model benevolence 4 inside are equipped with oblique bullet pin 10, the inclined-plane of mother module core 2 is withstood at oblique bullet pin 10 tops, play the oblique mounting groove 12 that needle spring 11 is positioned at male model benevolence 4 inside, oblique bullet pin 10 bottoms are mounted on the ramp of latch segment 13, latch segment 13 is fastenedly connected the backing plate 6 of bottom, row position screw 8 passes mother module core 2 successively, be anchored on backing plate 6 after the male model benevolence 4, the head of row position screw 8 is loaded in the perforation 15 of mother module core 2, the perforation of male model benevolence is up-small and down-big, little perforation 17 diameters in the top of male model benevolence are less than the head diameter of row position screw 8, in the male model benevolence bottom large perforation 16 spring 14 is housed, the two ends of spring 14 are mounted on large perforation 16 upper surfaces, male model benevolence bottom respectively, the upper surface of backing plate 6.
Backing plate is supported on the bottom connecting plate.
Its operation principle is as follows: during the demoulding, it is downward that the bottom connecting plate drives backing plate 6, it is downward that backing plate 6 drives row position screw 8, at this moment, the elastic force of spring 19 acts on large perforation 16 upper surfaces, male model benevolence bottom respectively, the upper surface of backing plate 6, make male model benevolence 4 keep original position motionless, simultaneously, backing plate 6 drives latch segments 13 and moves downward, and oblique bullet pin 10 is downward along oblique mounting groove 12 under the elastic force effect that plays needle spring 11, makes oblique bullet pin 10 tops finish loosing core to the product inclined hole, finish when loosing core or after, the lower surface of the head of row position screw 8 is pressed on male model benevolence 4, drives male model benevolence 4 and moves downward together, finishes the demoulding.
