Abstract

The invention discloses a linkage core-pulling device of a crosswise slide block and an inverted-buckling slide block, which comprises the crosswise slide block (1), the inverted-buckling slide block (2), a spring (3), an inclined batten (4) and an oil cylinder (5). The technical scheme provided by the invention is that the inverted-buckling slide block is slidingly arranged an inclined chute which is formed by the lower surface of the crosswise slide block and the inclined batten, a core of the crosswise slide block is crosswise pulled so as to lead the crosswise slide block fall back, the inverted-buckling slide block immovably and obliquely upward slides from the crosswise slide block along the inclined chute at first so as to lead a core to be pulled upwards on an inverted-buckling moulding surface, and then the crosswise slide block carries the inverted-buckling slide block to be commonly separated from a product. According to the invention, the problems and the defects that in the prior art, the structure is complex and the cost is high are overcome; and crosswise convex rib core-pulling and inclined inverted-buckling core-pulling can be realized at the same time through the linkage of the crosswise slide block and the inverted-buckling slide block, so that an injection mould can be structurally simplified, and the cost can be reduced.

Description

The interlock core-pulling device of a kind of transverse slider and back-off slide block
Technical field
The present invention relates to a kind of stripper apparatus of loosing core of injection mold, specifically be meant to be used for the slide block profile of horizontal convex rib structure that embeds goods and back-off structure the loose core a kind of transverse slider of the demoulding and the interlock core-pulling device of back-off slide block.
Background technology
The demoulding of loosing core of injection mold divides vertical, horizontal and oblique, and so-called be the folding direction along injection mold vertically, and so-called laterally be direction with said vertical quadrature, between vertical and horizontal between direction be oblique.
Not only be provided with horizontal convex rib structure for the outside of injection-molded item and be provided with not only back-off structure and the two but also parallel closing on; As; A kind of automobile filter shell products; Consult Fig. 5, the prior art injection mold adopts independently transverse slider mechanism to the demoulding of laterally loosing core of the horizontal convex rib structure of goods respectively, adopts independently tiltedly top sliding block mechanism that the back-off structure of goods is carried out the demoulding of loosing core of oblique top back-off; So make injection mold structure complicated, cost occupies high, and therefore, there is complex structure in prior art, the problems and shortcomings that cost is high.
Summary of the invention
Problems and shortcomings to above-mentioned prior art existence; The present invention adopts the back-off slide block is slidingly arranged in the oblique chute that the following and oblique press strip by transverse slider constitutes; Utilize retreating that transverse slider laterally looses core, the back-off slide block upwards looses core the back-off profile along oblique chute geocline as you were to upwards skidding off transverse slider earlier, carries the technical scheme that the back-off slide block breaks away from goods jointly by transverse slider again; The interlock core-pulling device of a kind of transverse slider and back-off slide block is provided; Be intended to interlock through transverse slider and back-off slide block and come to accomplish simultaneously that horizontal convex tendon is loosed core and oblique back-off is loosed core, make injection mold reach simplified structure, the purpose that reduces cost.
The objective of the invention is to realize like this: the interlock core-pulling device of a kind of transverse slider and back-off slide block; Comprise transverse slider, back-off slide block, spring, oblique press strip, oil cylinder, wherein: described transverse slider is the steel slide block of loosing core along laterally moving right of mould when being slidingly arranged in top, the demoulding of dynamic model support plate; The left surface of transverse slider is provided with the profile that the external partial convex tendon shape face with goods matches; Be provided with below the transverse slider and be inclined upwardly from right to left and the oblique chute of left end opening, the bottom land of said oblique chute is provided with oblong groove and is called and stirs groove, and the right-hand member cell wall place of said oblique chute is provided with the spring resettlement groove of settling spring;
Described back-off slide block is the block steel components of flat rectangular, and the left end of back-off slide block is provided with the back-off profile that the external partial back-off shape face with goods matches, and is fixed with the columniform pin of stirring protruding upward above the back-off slide block;
Described spring is a cylindroid helical-coil compression spring;
Described oblique press strip is that a left side is high right low, is the block steel components of wedge shape on inclined-plane above; That the right of oblique press strip top also is provided with is corresponding with the said spring resettlement groove position of transverse slider, the telescopic spring groove of the flexible purposes of ammunition feed spring;
The hydraulically extensible executive component of described oil cylinder for constituting by cylinder body and piston rod;
The back-off slide block slides and is arranged in the said oblique chute of transverse slider; Back-off slide block said stirs pin and slides and insert the said of transverse slider and stir in the groove; Oblique press strip is held in back-off slide block slip clamp in the said oblique chute of transverse slider with following fixed connection of transverse slider; Spring is contained in the spring resettlement groove of transverse slider, and the left end of spring contacts the right-hand member at the back-off slide block; The cylinder body of oil cylinder be positioned at transverse slider below, be fixedly connected in the resettlement groove that is provided with above the dynamic model, the piston rod of oil cylinder is fixedly connected with the right-hand member of transverse slider through contiguous block.
Operation principle and beneficial effect
During work, the mould die sinking, moving, cover half separates; Oil cylinder 5 drives transverse slider and laterally moves right, and the convex tendon profile of transverse slider looses core from the convex rib structure of goods, meanwhile; The back-off slide block is under the auxiliary promotion of spring; Ground as you were is earlier along the oblique transverse slider that upwards skids off of oblique chute, makes the back-off profile of back-off slide block be able to upwards to loose core the back-off structure of goods, along with transverse slider continues laterally to move right; When the said left cell wall of stirring groove of transverse slider touch the back-off slide block said when stirring pin, transverse slider drives the back-off slide block and moves laterally jointly away from other parts of goods.
Because this apparatus structure is simple, and the interlock through transverse slider and back-off slide block accomplishes simultaneously the demoulding that horizontal convex tendon is loosed core and loosed core with oblique back-off, so injection mold is simplified the structure, and reduced cost.
Above-mentioned; The present invention adopts the back-off slide block is slidingly arranged in the oblique chute that the following and oblique press strip by transverse slider constitutes; Utilize retreating that transverse slider laterally looses core, the back-off slide block upwards looses core the back-off profile along oblique chute geocline as you were to upwards skidding off transverse slider earlier, carries the technical scheme that the back-off slide block breaks away from goods jointly by transverse slider again; Overcome prior art and had complex structure; The problems and shortcomings that cost is high, a kind of transverse slider that is provided and the interlock core-pulling device of back-off slide block, the interlock through transverse slider and back-off slide block accomplishes simultaneously that horizontal convex tendon is loosed core and oblique back-off is loosed core; Make injection mold reach simplified structure, the purpose that reduces cost.
