The utility model has the advantages that: the utility model discloses an inner circle mold insert and outer lane mold insert, the inner circle mold insert includes interior mold insert pole and interior inlay piece seat, the tip of interior mold insert pole is the shaping end, the outer lane mold insert include outer mold insert hole and with the shaping hole that outer inlay piece hole link up, interior mold insert pole inserts in the shaping hole, and the terminal surface of interior inlay piece seat and the end face contact of outer lane mold insert, the downthehole auxiliary spring who overlaps on interior mold insert pole that is equipped with of outer inlay piece, be equipped with the spacing groove on the outer wall of outer lane mold insert, be equipped with the locating part on the interior inlay piece seat, and be equipped with the stopper on the locating part, this stopper is located the spacing groove and can remove in the spacing groove.
Glue the position through above-mentioned structure with the product of complicacy and shape respectively on two parts, a die sinking action realizes two parts shaping parts and divides twice drawing of patterns: firstly, the part of the inner ring insert is drawn out, the outer ring insert is propped against the outer ring bone position and is not moved, and the glue position of the part of the inner ring insert is easy to demould; and the outer ring mold insert is drawn out, so that the position of the outer ring bone has flexibility, the mold sticking force is small, and the mold sticking force is perfectly dispersed.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is an exploded view of the present invention;
fig. 2 is a cross-sectional view of the present invention;
fig. 3 is a perspective view of the present invention.
Detailed Description
Referring to fig. 1 to 3, the utility model discloses a secondary core-pulling mold structure, which comprises an inner ring insert 1 and an outer ring insert 2, wherein the inner ring insert 1 comprises an inner insert rod 3 and an inner insert seat 4, the end part of the inner insert rod 3 is a forming end 5, the structure of the forming end 5 can be designed correspondingly according to the structure of an injection molding product, so that the specific structure of the forming end 5 is not detailed, the outer ring insert 2 comprises an outer insert hole 7 and a forming hole 6 communicated with the outer insert hole 7, the diameter of the outer insert hole 7 is larger than that of the forming hole 6, the inner insert rod 3 is inserted into the outer insert hole 7 and the forming hole 6, the forming hole 6 is formed by matching a round hole with the forming end 5, the end surface of the inner insert seat 4 is limited by the end surface contact with the outer ring insert 2, an auxiliary spring (not shown in the figure) sleeved on the inner insert rod 3 is arranged in the outer insert hole 7, one end of the auxiliary spring is in contact with the bottom surface of the hole of the outer insert hole 7, the other end of the auxiliary spring is in contact with the end surface of the inner insert seat 4, the outer wall of the outer ring insert 2 is provided with a limiting groove 8, the inner insert seat 4 is provided with a limiting part 9, the limiting part 9 is fixed on the inner ring insert 1, the four sides are respectively provided with one limiting block 10, and the limiting block 10 is positioned in the limiting groove 8 and can move in the limiting groove 8.
The outer ring insert 2 is provided with an accommodating groove 11 with one end communicated with the outside on the outer wall, the limiting groove 8 is arranged in the accommodating groove 11, and the limiting part 9 is arranged in the accommodating groove 11, so that the limiting part 9 does not protrude out of the outer surface of the outer ring insert 2, and the structure is compact.
The inner insert seat 4 is provided with a T-shaped sliding block 14, the T-shaped sliding block 14 is in sliding fit with a T-shaped sliding groove 12 on a switching sliding block 13, and the structure can realize that the transverse movement of the switching sliding block 13 drives the inner insert seat 4 to vertically move.
The structural principle is briefly described as follows: when the machine is opened, the switching slide block 13 is driven to move transversely, the switching slide block 13 drives the inner ring insert 1 to move downwards through the T-shaped sliding groove 12 and the T-shaped slide block 14, the inner ring insert rod 3 and the forming end 5 are firstly extracted from an injection molding piece to realize primary core extraction, when the inner ring insert 1 is extracted, the limiting block 10 also moves in the limiting groove 8, after the inner ring insert 1 is extracted, the limiting block 10 also moves to the end part of the limiting groove 8, so that the limiting block 10 extrudes the inner ring insert 2 to drive the outer ring insert 2 to move and extract from the injection molding piece to realize secondary core extraction, in the process, in order to avoid driving the outer ring insert 2 when the inner ring insert 1 is extracted, an auxiliary spring sleeved on the inner ring insert rod 3 is arranged in the insert hole, and the auxiliary spring can extrude the outer ring insert 2 when the inner ring insert 1 is extracted through the elastic force of, thereby guarantee the stability of outer lane mold insert 2, can not cause the fish tail to the injection molding surface.
The above detailed description is given to a secondary core-pulling mold structure provided by the embodiment of the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
