By utilizing the die structure, one-step molding of a product that requires core pulling at the inner part with an undercut, of a lower hole can be realized, the finished product has good accuracy and quality, and the production efficiency is high. The die structure comprises the product, and an undercut part is formed at the inner part of the lower hole of the product The die structure also comprises a rear die insert, and is characterized in that the rear die insert comprises a center insert and a side sliding block insert; the center insert is propped against at the center of the lower hole of the product; the lower part of the center insert is firmly connected with a lower sliding block; the center insert is provided with an installation inclined surface which inclines outwards from top to bottom and corresponds to the undercut part; the lower sliding block is provided with a slant installation slot in the position corresponding to the installation inclined surface.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind ofly by large slide block, to drive small slide block to 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, through following process, form final finished 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 utility model provides a kind of and has driven small slide block to complete the mould structure of loosing core by large slide block, can 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 by large slide block, drive small slide block to 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 side concave portion, it also comprises rear mold mold insert, it is characterized in that: described rear mold mold insert comprises 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 inner side 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, between the bottom of described sidepiece slide block mold insert and described lower slider, be provided with spring.
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 integral piece structure.
The below of the oblique mounting groove of described lower slider is provided with 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 screw head installation cavity, stop screw is oblique runs through the lower surface that is installed in described sidepiece slide block mold insert after described gathering sill, spring fitting groove, the head of described stop screw is positioned at described screw head installation cavity, between the head of the described stop screw under matched moulds state and described gathering sill lower end, leaves distance B.
Adopt after structure of the present utility model, lower slider drives center mold insert to bottom knockout, due to the existence of spring, sidepiece slide block mold insert can not be moved down, it can remain on original height, now, due to the existence of T-shaped groove, sidepiece slide block mold insert level is moved inward, and then make sidepiece slide block mold insert and side concave portion complete the demoulding, can 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.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
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 inner side 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, between the bottom of sidepiece slide block mold insert 4 and lower slider 5, be 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 the lower surface that is installed in sidepiece slide block mold insert 4 after gathering sill 11, spring fitting groove 10, 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 matched moulds state and gathering sill 11 lower ends, leaves distance B.
Its operation principle is as follows: lower slider 5 drives center mold insert 3 to bottom knockout, due to the existence of spring 9, sidepiece slide block mold insert 4 can not be moved down, it can remain on original height, now, due to the existence of T-shaped groove 8, sidepiece slide block mold insert 4 levels are moved 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 overall 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).
