Abstract

The utility model discloses a slide block withdrawing structure, which comprises a first slide block arranged in a die kernel, wherein, the first slide block can enter and slide out of the die kernel; one side of the corresponding form board of the first slide block is provided with a sliding chute; a second slide block is arranged in the sliding groove, wherein, a motion space is arranged in the sliding chute and can contact with a product and is involved in molding of the product; the second slide block is provided with a guide hole; a straight guide post is arranged correspondingly to the guide hole and is fixed on the form board; the straight guide post can be pivoted with the second slide block at the guide hole; the second slide block withdraws with the help of the first slide block; when the die is opened, the second slide block moves relatively to the first slide block under the action of the straight guide post, so as to make the first slide block smoothly separate and withdraw from the die kernel. The slide block withdrawing structure has simple structure and practical use, as well as effectively solves the problem of difficult demolding.

Description

The slide block exit structure

Technical field

The utility model relates to a kind of slide block structure, particularly relates to a kind of slide block exit structure.

Background technology

Slide block can be used as the assistance formed product.Some product has special construction, can't directly finish moulding by mould, and uses slide block to assist, die sinking after formed product, and slide block breaks away from product and withdraws from the mould die, and is convenient and practical.

But sticking phenomenon occurs between slide block and product sometimes, and influence product quality; Especially,, product is pulled, and influenced product quality when higher in the shape of product complexity of being assisted moulding by slide block or glue position if the slide block structure that adopts us to use always causes the product stripping difficulty easily.

Summary of the invention

The purpose of this utility model is to propose a kind of slide block time-delay exit structure, and the product that slide block causes when having solved die sinking is pulled problem.

The technical solution of the utility model is: a kind of slide block exit structure, and it comprises: one first slide block, be arranged in the die, this first slide block can enter, skid off this die; Simultaneously, this first slide block corresponding templates simultaneously offers a chute; One second slide block is arranged in this chute, activity space is arranged in chute, and can contact with product, and participate in formed product; This second slide block is provided with a guide hole; Guide pillar always to should the guide hole setting, be fixed on the template; Can articulate this second slide block in guide hole; This straight guide pillar is the inclined plane near second slide block, one end surfaces, reduces this this end of straight guide pillar and second slide block and touches, rubs.

The utility model is the mode that adopts the slide block combination, withdraw from die and product break away from first slide block, utilization is arranged at the second slide block contact product, when first slide block breaks away from product, this second slide block can resist product, make the smooth and product disengaging of first slide block, the slide block combination is then withdrawed from die smoothly after first slide block breaks away from product; Simple and practical.

The specific embodiment

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.

Present embodiment is for participating in the slide block exit structure of high gum place products moulding.

A kind of slide block exit structure as shown in Figure 1, this structure comprises: one first slide block 20, be arranged in the die, it participates in high gum place products 10 moulding, can drive this first slide block 20 by the Angle Pin 300 that is arranged at cope match-plate pattern 30 and enter, skids off this die; Simultaneously, these first slide block, 20 corresponding cope match-plate pattern 30 one sides offer a chute.

One second slide block 21 is arranged in this chute, can move in chute; This second slide block 21 is provided with a guide hole 211, and is being provided with a projection 212 near product 10 ends; This projection 212 can touch product 10, and participates in product 10 moulding; When first slide block 20 and product 10 disengagings, when phenomenon was drawn in 10 generations to product, this projection 212 can resist product 10, and makes product 10 be unlikely to distortion in dilatory.

Guide pillar 22 always, to being provided with by guide hole 211, are fixed on the cope match-plate pattern 30; Can articulate this second slide block 21 in guide hole 211; This straight guide pillar 22 is beaten the R angle near second slide block, 21 1 ends and is handled, and is inclined plane 220 and make this end surfaces, reduces these straight guide pillar 22 these ends and second slide block 21 and touches, rubs.

One elastic component, one end is arranged in second slide block 21, and the other end is connected to first slide block, 20 chutes, one side, can be used as the driving force of second slide block 21, simultaneously also can limit this activity of second slide block 21 in chute, prevent second irregular movement of slide block 21 in chute.This elastic component can be spring 210, and in the present embodiment, the spring 210 that this is arranged at second slide block 21 is connected to the corresponding side surface of this first slide block 20 near product 10 sides.

This second slide block 21 is under the effect of spring 210, and its initial position is in chute near product 10 1 sides.

The beginning matched moulds, cope match-plate pattern 30, lower bolster 31 close up, and Angle Pin 300 makes the slide block 20 of winning near the die certain distance, and this moment, straight guide pillar 22 entered into the guide hole 211 of second slide block 21; Template continues to close up, and first slide block 20 enters into die, and this straight guide pillar 22 makes second slide block 21 be in the chute away from die one end, and spring 210 is compressed, and matched moulds is finished; And the projection 212 of this second slide block 21 participates in product 10 moulding.

As shown in Figure 2, begin die sinking after product 10 moulding, cope match-plate pattern 30, lower bolster 31 separate, and the Angle Pin 300 that is arranged at cope match-plate pattern 30 can make first slide block 20 do and skid off the die motion, and second slide block 21 is in close product 10 sides of chute under straight guide pillar 22 effects; The projection 212 of this second slide block 21 contacts with product 10 always, and when first slide block 20 separated with product 10, this projection 212 can resist product 10, avoids first slide block 20 to be difficult to break away from and the dilatory deformation that produces with product 10.Continue die sinking, straight guide pillar 22 withdraws from guide hole 211, and spring 210 can make second slide block 21 keep chute near product 10 ends; And Angle Pin 300 can make this first slide block 20 and second slide block 21 withdraw from die smoothly, and (as shown in Figure 3) finished in die sinking.

The utility model is the mode that adopts the slide block combination, withdraw from die and product 10 break away from first slide block 20, utilization is arranged at projection 212 contact products 10 of second slide block 21, when phenomenon is drawn in 10 generations of 20 pairs of products of first slide block, this projection 212 can resist product 10, can make product 10 be unlikely to distortion in dilatory, the slide block combination is then withdrawed from die smoothly after breaking away from product 10.
