Abstract
The invention provides a mould structure for completing core pulling by driving a small sliding block by a large sliding block. A product can be formed once when the interior of a lower hole requiring the core pulling is provided with a lateral dent, so that a finished product is good in precision, good in quality and high in production efficiency. The mould structure comprises the product, wherein the interior of the lower hole of the product is provided with a lateral dent part, and the mould structure also comprises a rear mould insert. The mould structure is characterized in that the rear mould insert comprises a central insert and a lateral sliding block insert; the central insert is arranged in the center of the lower hole of the product in an ejecting mode; the lower part of the central insert is connected with a lower sliding block in a fastening manner; the central insert, corresponding to the lateral dent part, is provided with a mounting inclined surface inclined outwards from top to bottom; the lower sliding block, corresponding to the position of the mounting inclined surface, is provided with an inclined mounting groove.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially and a kind ofly drive small slide block by large slide block and complete the mould structure of loosing core.
Background technology
When the inside of the bottom hole that goods are loosed core at needs has again side recessed, existing slide block mechanism can not once be extracted mold insert out, need to be by goods first after in-mold molding, form final finished through following process again, need post forming, because the dimensional accuracy of post forming is wayward, make the low precision, of poor quality of finished product, and post forming makes production efficiency low.
Summary of the invention
The invention provides and a kind ofly drive small slide block by large slide block and complete the mould structure of loosing core, but one-shot forming when it makes the inside of the bottom hole that goods loose core at needs have again side recessed, and the precision of finished product is good, quality is good, and production efficiency is high.
A kind ofly drive small slide block by large slide block and complete the mould structure of loosing core, its technical scheme is such: it comprises goods, the inside of the bottom hole of described goods is with the side concave portion, it also comprises the rear mold mold insert, it is characterized in that: described rear mold mold insert comprises the center mold insert, sidepiece slide block mold insert, described center mold insert is mounted on the center of the bottom hole of described goods, the bottom of described center mold insert is fastenedly connected lower slider, described center mold insert is provided with from top to bottom outward-dipping installation inclined-plane corresponding to described side concave portion, described lower slider is provided with oblique mounting groove corresponding to the position on described installation inclined-plane, described installation inclined-plane, the homonymy of oblique mounting groove is provided with T-shaped groove, the upper outside of described sidepiece slide block mold insert is mounted on described side concave portion, the inboard of described sidepiece slide block mold insert is flush-mounted in described T-shaped groove, the lower end of described sidepiece slide block mold insert is positioned at described oblique mounting groove, be provided with spring between the bottom of described sidepiece slide block mold insert and described lower slider.
It is further characterized in that: described sidepiece slide block mold insert lays respectively at two side positions of described center mold insert;
Described center mold insert, lower slider can be combined to form the integral piece structure.
The below of the oblique mounting groove of described lower slider is provided with the spring fitting groove, described spring is positioned at described spring fitting groove, described lower slider is provided with gathering sill, the bottom of described gathering sill is the screw head installation cavity, stop screw is oblique runs through after described gathering sill, spring fitting groove the lower surface that is installed in described sidepiece slide block mold insert, the head of described stop screw is positioned at described screw head installation cavity, between the head of the described stop screw under the matched moulds state and described gathering sill lower end, leaves distance B.
After adopting structure of the present invention, lower slider drives the center mold insert to bottom knockout, due to the existence of spring, makes sidepiece slide block mold insert can not move down, it can remain on original height, now, due to the existence of T-shaped groove, make sidepiece slide block mold insert level move inward, and then make sidepiece slide block mold insert and side concave portion complete the demoulding, but one-shot forming when it makes the inside of the bottom hole that goods loose core at needs have again side recessed, the precision of finished product is good, quality is good, and production efficiency is high.
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises goods 1, the inside of the bottom hole of goods 1 is with side concave portion 2, it also comprises center mold insert 3, sidepiece slide block mold insert 4, center mold insert 3 is mounted on the center of the bottom hole of goods 1, the bottom of center mold insert 3 is fastenedly connected lower slider 5, center mold insert 3 is provided with from top to bottom outward-dipping installation inclined-plane 6 corresponding to side concave portion 2, lower slider 5 is provided with oblique mounting groove 7 corresponding to the position that inclined-plane 6 is installed, inclined-plane 6 is installed, the homonymy of oblique mounting groove 7 is provided with T-shaped groove 8, the upper outside of sidepiece slide block mold insert 4 is mounted on side concave portion 2, the inboard of sidepiece slide block mold insert 4 is flush-mounted in T-shaped groove 8, the lower end of sidepiece slide block mold insert 4 is positioned at oblique mounting groove 7, 5 of the bottom of sidepiece slide block mold insert 4 and lower slider are provided with spring 9.Sidepiece slide block mold insert 4 lays respectively at two side positions of center mold insert 3; The below of the oblique mounting groove 7 of lower slider 5 is provided with spring fitting groove 10, spring 9 is positioned at spring fitting groove 10, lower slider 5 is provided with gathering sill 11, the bottom of gathering sill 11 is screw head installation cavity 12, stop screw 13 is oblique runs through after gathering sill 11, spring fitting groove 10 lower surface that is installed in sidepiece slide block mold insert 4, the head 14 of stop screw 13 is positioned at screw head installation cavity 12, between the head 14 of the stop screw 13 under the matched moulds state and gathering sill 11 lower ends, leaves distance B.
Center mold insert 3, lower slider 5 can be combined to form the integral piece structure.
Its operation principle is as follows: lower slider 5 drives center mold insert 3 to bottom knockout, existence due to spring 9, make sidepiece slide block mold insert 4 can not move down, it can remain on original height, now, existence due to T-shaped groove 8, make sidepiece slide block mold insert 4 levels move inward, and then make sidepiece slide block mold insert 4 and side concave portion 2 complete the demoulding, when spring 9 elongations reach distance B afterwards, the head 14 of stop screw 13 is close to gathering sill 11 lower surfaces, now lower slider 5 drives center mold insert 3, sidepiece slide block mold insert 4 completes the whole demoulding together downwards, it is (not shown in FIG. that front mould thimble action afterwards ejects front mould by goods 1, belong to existing mature structure).
