Abstract
The utility model discloses a go position and postpone to loose core structure for injection mold, go position seat and fix the layering on movable mould including swing joint in the movable mould, the position seat of going is equipped with a line position mold insert, sliding connection has a shovel base on the layering, the one end of shovel base is connected with actuating mechanism, the basic other end of shovel removes in order to drive the line position relative movable mould of seat in wearing to locate to go the position seat, the shovel base is including integrative sliding part and the promotion section that links to each other, sliding part and actuating mechanism link to each other and are equipped with first slope acute angle between the layering, the front end of promotion section wear to locate to go in the seat of position and the layering between be equipped with second slope acute angle. The utility model discloses an inclination that designs two sections differences on the base at the shovel goes the position seat in order to withstand, accomplishes the back moulding plastics, offsets the pressure of moulding plastics, reduces the actuating mechanism atress, prevents to go to retreat, compare in prior art, no longer need extraly increase the drive of the basic hydraulic cylinder of shovel and withstand line position seat, reduced taking of structure space to mould volume and mechanism's part quantity have been reduced.
Description
Technical field
The utility model relates to a kind of injection forming mold, and mainly a kind of line position for injection mold postpones pulled core structure.
Background technology
In existing injection mould structure, when there is inclined hole class back-off in the die sinking direction of plastic products, by common slide structure, fall back cause product offset to prevent line position, need after the line position of hydraulic jack driving, increase the driving of a shovel base fluid compressing cylinder again to withstand, can prevent Injection line from retreating although this shovel base of the mould of this structure is driven by hydraulic jack, but mould structure meeting more complicated, the procedure of processing of correlated parts is various, precise requirements is higher, and assembly difficulty is large.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of structure simple, and when avoiding injection moulding, line position is moved back and caused the line position for injection mold of product offset to postpone pulled core structure.
The purpose of this utility model is achieved through the following technical solutions:
Line position for injection mold postpones pulled core structure, comprise the line position seat be movably connected in dynamic model and the press strip be fixed in dynamic model template, described line position seat is provided with slide insert, described press strip slidably connects a shovel base, one end of described shovel base is connected with driving mechanism, the other end of described shovel base is arranged in line position seat to drive line position seat to move relative to dynamic model, it is characterized in that, described shovel base comprises the connected sliding part of one and pushing part, described sliding part is connected with driving mechanism and also and between press strip is provided with the first acute rake angle, the front end of described pushing part is arranged in line position seat and also and between press strip is provided with the second acute rake angle.
Preferably, the angle value of described first acute rake angle is less than the angle value of the second acute rake angle.
Preferably, the angle value of described first acute rake angle is 5 °, and the angle value of described second acute rake angle is 20 °.
Concrete, described driving mechanism is hydraulic jack.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model to withstand line position seat by design two sections of different angles of inclination on shovel base, after injection moulding completes, is offset injection pressure, is reduced driving mechanism stressed, prevent line position from retreating; Compared to prior art, no longer need extra increase shovel base fluid compressing cylinder to drive and withstand line position seat, decrease taking of structure space, and reduce mould volume and mechanism part quantity.
Accompanying drawing explanation
Fig. 1 is stereoscopic mechanism schematic diagram of the present utility model.
Fig. 2 is assembly structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figures 1 and 2, the present embodiment provides a kind of line position for injection mold to postpone pulled core structure, comprise the line position seat 1 be movably connected in dynamic model and the press strip 2 be fixed in dynamic model template, described line position seat 1 is provided with slide insert 3, described press strip 2 slidably connects a shovel base 4, one end of described shovel base 4 is connected with driving mechanism, the other end of described shovel base 4 is arranged in line position seat 1 to drive line position seat 1 to move relative to dynamic model, described shovel base 4 comprises the connected sliding part 401 of one and pushing part 402, described sliding part 401 is connected with driving mechanism and also and between press strip 2 is provided with the first acute rake angle, the front end of described pushing part 402 is arranged in line position seat 1 and also and between press strip 2 is provided with the second acute rake angle.
Wherein, the angle value of described first acute rake angle is less than the angle value of the second acute rake angle.
One as such scheme is preferred, and the angle value of described first acute rake angle is 5 °, and the angle value of described second acute rake angle is 20 °.
In the present embodiment, described driving mechanism is hydraulic jack 5.
Operation principle of the present utility model is as follows:
After mold injection, die sinking, dynamic model retreats, because hydraulic jack 5 and press strip 2 are fixed in template, and slide insert 3 is fixed on line position seat 1, line position seat 1 is provided with the access opening for pushing part 402 slide anteroposterior, after hydraulic jack 5 promotion shovel base 4 travels forward, shovel base 4 needs this part of sliding part 401 of first having moved in the guide direction of press strip 2, thus line position seat 1 lag motion can be made, then shovel base 4 and promote line position seat 1 by pushing part 402 again, complete and loose core, and this process continues to have withstood line position seat by the acute rake angle of sliding part 401, counteract injection pressure, reduce driving mechanism stressed, prevent line position from retreating.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
