Description
Technical field
The utility model relates to mould structure technical field, particularly a kind of internal slide structure of mould.
Background technology
Known from institute, in order to improve product quality and production efficiency, generally utilize Inner slide injection mold to produce in manufacturing enterprise, its operating efficiency is high, easy to operate; And the shaping molding cycle of thermoplastic injection is short, production efficiency is high, the wearing and tearing of melt to mould are little, can complicated, the picture on surface of forming shape and mark is clear, dimensional accuracy is high plastic in large quantity.
But existing Design of Dies is unreasonable, production efficiency is low and the product percent of pass produced is low, thus indirectly adds the Productive statistics fund cost of enterprise, and its irrational design simultaneously also directly causes the shortening in its service life.
And for the product of inner back-off, the design due to slide structure is unreasonable restricted, can not carry out die sinking, thus reduce production efficiency by oblique top.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of internal slide structure of mould, effectively can improve stability and the reliability of mould operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of internal slide structure of mould, comprise rear mold mold insert, drive rod, large line position and tunnel line position seat, one end of described drive rod is arranged on tunnel line position seat, and large line position drives described drive rod to move to described rear mold mold insert; Have the left passage for tunnel line position movement on the left of described rear mold mold insert, have the right passage passed through for drive rod on the right side of described rear mold mold insert, described left passage is than right channel width and should both be communicated with; Be provided with the groove inserted for described drive rod in described tunnel line position, be provided with stop collar in this groove, this stop collar is by spring and the line position generation relative displacement of described tunnel; The limited block for drive rod described in snap close is provided with in the left passage of described rear mold mold insert.
In technique scheme, be positioned at described left passage bottom and be provided with the first depression and the second depression that arrange along drive rod direction of insertion, be connected by inclined-plane between first depression caves in second, described first depression is deeper than described second depression, the transition back and forth between described first depression, the second depression of described limited block.
In technique scheme, the inserting paragraph of described drive rod is provided with the depressed part snapped in for described limited block.
In technique scheme, line position bottom surface, described tunnel is provided with the perforate held described limited block and insert.
The beneficial effects of the utility model are: the overall structure of mould is simple and compact, save the cost of Making mold and space, die sinking when effectively can solve interiors of products back-off and a difficult problem for matched moulds.Utilize coordinating between drive rod with tunnel line position internal position limited sleeve, realize the stable running to mould die sinking and matched moulds, improve the operation stability of mould, reliability and production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of internal slide structure of mould, comprise rear mold mold insert 1, drive rod 2, large line position 3 and tunnel line position seat 4, one end of described drive rod 2 is arranged on tunnel line position seat 4, and large line position 3 drives described drive rod 2 to move to described rear mold mold insert 1; Have the left passage 5 for tunnel line position 17 movement on the left of described rear mold mold insert 1, have the right passage 6 passed through for drive rod 2 on the right side of described rear mold mold insert 1, described left passage 5 is wider than right passage 6 and should both be communicated with; Being provided with the groove 7 inserted for described drive rod 2 in described tunnel line position 17, being provided with stop collar 8 in this groove 7, there is relative displacement by spring 9 and described tunnel line position 17 in this stop collar 8; The limited block 10 for drive rod described in snap close 2 is provided with in the left passage 5 of described rear mold mold insert 1.Be provided with in large line position 3 strand tooth loose core 11, drive rod 2 is arranged at this strand tooth and looses core in the inner chamber of 11, drive rod 2 can along strand tooth loose core 11 axis move; Large line position 3 is fixedly connected with tunnel line position seat 4 by guide rod 12, and when described large line position 3 moves to rear mold mold insert 1, large line position 3 drives tunnel line position seat 4 to move, and the drive rod 2 that so one end is fixed on tunnel line position seat 4 also follows movement.
Wherein, be positioned at described left passage 5 bottom surface and be provided with the first depression 13 and the second depression 14 arranged along drive rod 2 direction of insertion, first depression 13 and second is caved between 14 and is connected by inclined-plane 15, described first depression 13 is deeper than described second depression 14, the transition back and forth between described first depression 13, second depression 14 of described limited block 10.
Wherein, the inserting paragraph of described drive rod 2 is provided with the depressed part 16 snapped in for described limited block 10.Limited block 10 engages the state after realizing matched moulds with drive rod 2 to be fixed.
Wherein, line position 17 bottom surface in described tunnel is provided with the perforate held described limited block 10 and insert.
Operation principle of the present utility model: after matched moulds, drive rod 2 inserts the right passage 6 in rear mold mold insert 1, the tunnel line position 17 being arranged in left passage 5 is inserted into by right passage 6, drive rod 2 leans described stop collar 8, spring 9 is made to be in confined state, limited block 10 is in the second depression 14, and pass through tunnel in the top of limited block 10, the bottom surface opening of line position 17 engages with the depressed part 16 of drive rod 2, tunnel line position 17 is leaned extreme position by drive rod 2, and is fixed this position by limited block 10.
During die sinking, drive rod 2 resets and leaves rear mold mold insert 1, drive rod 2 is in the process leaving rear mold mold insert 1, limited block 10 is driven to move, and limited block 10 moves in the first depression 13 the most at last, limited block 10 drives tunnel line position 17 to move with drive rod 2 until the position of limited block 10 is fixed in the process of movement; Stop collar 8 loses leaning of drive rod 2, and the active force due to spring 9 makes stop collar 8 move to the position of drive rod 2, and is covered by the opening residing for limited block 10, prevents limited block 10 from playbacking.
Above embodiment is just to illustrate instead of restriction the utility model, therefore all equivalences done according to the method described in the utility model patent claim change or modify, and are included in the utility model patent claim.
