Abstract
The utility model discloses a mechanical linkage secondary slant-ejecting structure for an injection mould, comprising a slant ejecting rod, a slant ejecting sliding block, a slant-ejecting ejector pin plate component, a vertical ejecting rod, a vertical-ejecting ejector-pin plate component, an ejector pin plate pushing rod, a tension rod sliding block, a disengaging slant block, a spring and a tension rod. The utility model is characterized in that the disengaging slant block is provided with an inclined plane socket; the vertical-ejecting ejector-pin plate component is fixed with the disengaging slant block; the slant-ejecting ejector pin plate component is fixed with the tension rod; and the disengaging slant block is in slip connection with the tension rod. The utility model adopts two groups of ejector pin plate components and utilizes the elasticity of the spring to realize the separated working of the two groups of ejector pin plate components, thus finishing the two levels of vertical ejecting and slant ejecting demoulding operations; by adopting the mould of the utility model, the appearance size and thickness of the mould can be decreased effectively, thus greatly reducing the manufacturing cost and having the significant economic benefit.
Description
Technical field
The present invention relates to a kind of secondary oblique top mechanism, refer in particular to a kind of mechanical linkage secondary oblique top mechanism that injection mold is produced that is used for.
Background technology
In some complicated mould of plastics, goods the demoulding need carry out secondary even multistage loosing core or oblique top, existing technical solution is a kind of to be to adopt that oil cylinder hydraulic is multistage looses core, another kind is to adopt many group skewbacks oblique top that links in proper order, all there is the mould structure complexity in these technical schemes, appearance and size is big, defectives such as manufacturing cost height.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, the mechanical linkage secondary oblique top mechanism that a kind of dependable performance, die shape size are little, can effectively reduce die manufacturing cost is provided.
The present invention is achieved in that
A kind of mechanical linkage secondary oblique top mechanism that is used for injection mold, comprise angle ejector rod, oblique top slide block, oblique top ejector retainner plate assembly, straight push rod, straight top ejector retainner plate assembly, ejector retainner plate push rod, pull bar slide block, dropout skewback, spring and pull bar, described dropout skewback is provided with inclined plane groove, straight top ejector retainner plate assembly and dropout skewback are fixed, oblique top ejector retainner plate assembly and pull bar are fixed, and dropout skewback and pull bar are slidingly connected.
Described ejector retainner plate push rod and oblique top ejector retainner plate assembly are fixed.
Described pull bar slide block one end is fixedlyed connected the groove sliding-contact of the other end and dropout skewback by spring with straight top ejector retainner plate assembly.
Described oblique top slide block is fixed on the oblique top ejector retainner plate assembly, is slidingly connected by inclination T-slot and angle ejector rod.
Described dropout skewback and pull bar are slidingly connected by square groove.
The present invention is by adopting two groups of ejector retainner plate assemblies, utilize the elastic force of spring to realize the separation of two groups of ejector retainner plate assemblies work, thereby finish straight top, the operation of oblique top two-stage ejection device, adopt mould of the present invention can effectively reduce the appearance and size and the thickness of mould, thereby reduced manufacturing cost widely, had tangible economic benefit.
Description of drawings
Fig. 1 is the dynamic model structural representation that comprises injection mold of the present invention.
Fig. 2 is for pull bar slide block among Fig. 1 and take off the A of mouthful skewback to enlarged diagram.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As shown in Figure 1 and Figure 2, a kind of mechanical linkage secondary oblique top mechanism that is used for injection mold, comprise angle ejector rod 12, oblique top slide block 9, oblique top ejector retainner plate assembly 1, straight push rod 15, straight top ejector retainner plate assembly 2, ejector retainner plate push rod 8, pull bar slide block 5, dropout skewback 6, spring 4 and pull bar 7, described dropout skewback 6 is provided with inclined plane groove 601, straight top ejector retainner plate assembly 2 is fixing with dropout skewback 6, oblique top ejector retainner plate assembly 1 is fixing with pull bar 7, and dropout skewback 6 is slidingly connected with pull bar 7.
As shown in Figure 1, described ejector retainner plate push rod 8 is fixing with oblique top ejector retainner plate assembly 1.
As shown in Figure 1, described pull bar slide block 5 one ends are fixedlyed connected groove 601 sliding-contacts of the other end and dropout skewback 6 by spring 4 with straight top ejector retainner plate assembly 2.
As shown in Figure 1, described oblique top slide block 9 is fixed on the oblique top ejector retainner plate assembly 1, is slidingly connected by inclination T-slot 901 and angle ejector rod 12.
As shown in Figure 1 and Figure 2, described dropout skewback 6 is slidingly connected by square groove 701 with pull bar 7.
As shown in Figure 1 and Figure 2, mould is finished injection moulding, after the dynamic model die sinking makes workpiece 11 break away from cover half, ejector retainner plate push rod 8 promotes oblique top ejector retainner plate assembly 1 forward impelling, because the barb effect of pull bar slide block 5, oblique top ejector retainner plate assembly 1 drives straight top ejector retainner plate assembly 2 reach together by the pull bar on being fixed together 7, and the straight push rod 15 on the straight top ejector retainner plate assembly 2 promotes straight top mold insert and joins same angle ejector rod, oblique top mold insert and make workpiece 11 leave back-off on the dynamic mould core 10 obliquely together.When workpiece 11 leaves dynamic mould core 10 fully, the inclined-plane of pull bar slide block 5 just in time be fixed on Bottom clamp plate 3 on the inclined-plane of dropout skewback 6 grooves 601 contact, under the effect of ejector retainner plate push rod 8, oblique top ejector retainner plate assembly 1 continues reach, the inclined-plane pressure of dropout skewback 6 overcomes spring force to be made in the straight top of the pull bar slide block 5 indentations ejector retainner plate assembly 2, the pulling that pull bar 7 breaks away from straight top ejector retainner plate assembly 2, ejector retainner plate push rod 8 promotes 1 reach of oblique top ejector retainner plate assembly separately, oblique top slide block 9 on the oblique top ejector retainner plate assembly 1 promotes angle ejector rod 12 makes oblique top mold insert 14 be with workpiece 11 to leave straight top mold insert 13, finishes the stripping operation of workpiece 11.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
