Description

The slide block mechanism that secondary withdraws from

Technical field

The utility model relates to the slide block mechanism of plastic mould, the slide block mechanism that specifically a kind of secondary withdraws from.

Background technology

The overhead kick that has two different directions at the same place of product, and the exit axis of the direction of a wherein overhead kick and slide block mechanism adopts slide block structure of the prior art can't satisfy its production demand when vertical.See also Fig. 1 and Fig. 2, the same position of product 10 has two overhead kicks, and overhead kick 20 and slide block to go into the exit axis of son 30 vertical, if force die sinking, slide block is gone into son 30 and overhead kick 20 positions of product 10 will be broken, and destroys the structure of product 10.

The utility model content

Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, the slide block mechanism that provides a kind of secondary to withdraw from.

The slide block mechanism that the utility model provides a kind of secondary to withdraw from includes son, body, Angle Pin.This go into the son by first go into son, second go into son and the 3rd go into the son form.This first goes into the end that son is located at body, this second go into son be located in first go into the son with body in, and the one end is provided with the inclined-plane, offer "T"-shaped draw-in groove on the inclined-plane of this end, the 3rd to go into sub-end face be the inclined-plane, and the gradient on inclined-plane that its gradient and second is gone into sub-end is consistent, and the 3rd inclined-plane of going into son is provided with "T"-shaped boss, the "T"-shaped draw-in groove that this "T"-shaped boss and second is gone on the sub-end chamfer engages, and the 3rd goes into son and can slide along this second inclined-plane of going into son.

This Angle Pin is located in body and second goes in the Angle Pin hole that son offers, and this second Angle Pin hole of going on the son has one section dislocation distance with respect to the Angle Pin hole on the body.

More excellent, described body and second is gone into sub-end and is provided with the bundle piece.

More excellent, on the described body and body below is provided with wear-resistant block.

Compared with prior art, the utility model can withdraw from the overhead kick of the different directions on the product, has guaranteed the integrality of product.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 3 and Fig. 4, the structural representation and second that is respectively the slide block mechanism that the utility model secondary withdraws from is gone into son and the 3rd and is gone into the sub schematic diagram that cooperates.The son of going into of this slide block mechanism is gone into son 101, second by first and is gone into son the 102 and the 3rd and go into son and 103 form.This first goes into the end that son 101 is located at body 104, this second go into the son 102 be located in first go into the son 101 with body 104 in, and this second end of going into son 102 is provided with inclined-plane 110, offer "T"-shaped draw-in groove 111 on the inclined-plane 110 of this end, the 3rd to go into sub 103 end faces be inclined-plane 112, the gradient on inclined-plane 110 that its gradient and second is gone into sub 102 ends is consistent, and the 3rd inclined-plane 112 of going into son 103 is provided with "T"-shaped boss 113, the "T"-shaped draw-in groove 111 that this "T"-shaped boss 113 and second is gone on sub 102 end chamfer 110 engages, and the 3rd goes into son 103 and can second go into son 102 inclined-plane 110 and slide along this.

The end of going into son 102 at body 104 and second is provided with bundle piece 105, when matched moulds, this bundle piece 105 is fitted with the side that body 104 and second is gone into son 102, after preventing that slide block mechanism is subjected to injection pressure, and retreat, body 104 also is provided with wear-resistant block 106,107 with position and body 104 belows that bundle piece 105 is fitted, can avoid body 104 to wear and tear.Angle Pin 114 is located in body 104 and second goes in the son 102 Angle Pin holes of offering 108,109, and this second Angle Pin hole 109 of going on the son 102 has one section dislocation distance with respect to the Angle Pin hole 108 on the body 104.

See also Fig. 5 and Fig. 6, be respectively the enlarged diagram that withdraws from a-quadrant among action signal and Fig. 5 the first time of the slide block mechanism that the utility model secondary withdraws from.During die sinking, the caster 115 of mould separates with male model plate 116, the bundle piece 105 that is fixed on the caster 115 moves upward with this caster 115 with Angle Pin 114, because the second Angle Pin hole of going on the son 102 109 has one section dislocation distance (seeing also Fig. 3) with respect to the Angle Pin hole 108 on the body 104, therefore Angle Pin 114 can at first drive second and goes into son 102 and withdraw from backward, second goes into son 102 when withdrawing from backward, being fastened on the 3rd in the "T"-shaped draw-in groove 111 goes into son 103 and can move upward along this "T"-shaped draw-in groove 111, withdraw from the overhead kick 20 of product 10, finish the first time of slide block mechanism and withdraw from.

Please continue to consult Fig. 7, withdraw from the action schematic diagram second time of the slide block mechanism that withdraws from for the utility model secondary.The 3rd go into the son 103 withdraw from fully after, Angle Pin 114 continues to move upward, at this moment, the second Angle Pin hole of going on the son 102 109 is in the same plane with the Angle Pin hole 108 on the body 104, therefore Angle Pin 114 can drive bodies 104 and goes into son 102 with second and withdraw from, and makes first to go into son 101, second and go into son the 102 and the 3rd and go into the reverse-hook shape body portion that son 103 breaks away from product 10 fully.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
