Abstract

The utility model provides a slide block mechanism with time-lapse withdraw function, which comprises an insert and an inclined guide pillar. The insert comprises a first insert and a second insert which are stacked sequentially; inclined guide pillar holes are formed on the end surfaces of the first insert and the second insert in a penetrating manner; the inclined guide pillar penetrates through the inclined guide pillar holes formed on the first insert and the second insert; and a clearance distance is formed in each inclined guide pillar hole formed on the second insert. Compared with the prior art, the slide block mechanism can withdraw two barbs in different directions at the same part successfully under the circumstance that a product structure is not modified, and a slide block of the slide block mechanism has the advantages of simple structure and practicability.

Description

The slide block mechanism that time-delay is withdrawed from

Technical field

The utility model relates to the slide block drawing-out mechanism of plastic mould, the slide block mechanism that specifically a kind of time-delay is withdrawed from.

Background technology

Slide block mechanism is mold manufacturing industry a kind of barb drawing-out mechanism commonly used, can be applicable to that the overhead kick of most of product single direction is withdrawed from.But when having the overhead kick of two different directions at the same place of product, traditional slide block mechanism just can't satisfy its production demand.See also Fig. 1, be a product enlarged diagram with overhead kick of two different angles wherein, the same position of this product 10 has two overhead kicks 20,30, and the angle of overhead kick 20,30 is inconsistent, just can't withdraw from traditional slide block mechanism, at this moment, can only require the client to revise product structure or product is divided into two moulding.

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 time-delay to withdraw from.

The slide block mechanism that the utility model provides a kind of time-delay to withdraw from includes son, Angle Pin.This is gone into son and goes into son and second by first and go into son and be formed by stacking successively, this first is gone into son and second goes into sub-end face and offer the Angle Pin hole of running through with this, this second goes into the diameter in the Angle Pin hole on the son greater than this first diameter of going into the Angle Pin hole on the son, this Angle Pin is arranged in first goes in the Angle Pin hole that son and second goes into son, and second goes in the sub Angle Pin hole to have an empty avoiding distance at this.

More excellent, described first goes into son is provided with the bundle piece with this second end of going into son.

More excellent, described bundle piece is fixed in the caster of mould with screw.

More excellent, described second goes into sub-end face is provided with the backstop screw.

More excellent, described second goes into the son bottom is provided with wear-resistant block.

Compared with prior art, the utility model can withdraw from the overhead kick of two different directions at same position smoothly, and its slide block structure is simple, practical under the situation of not revising product structure.

Description of drawings

Fig. 1 is a product enlarged diagram with overhead kick of two different angles wherein.

Withdraw from the action schematic diagram first time of the slide block mechanism that Fig. 3 withdraws from for the utility model time-delay.

Withdraw from the action schematic diagram second time of the slide block mechanism that Fig. 4 withdraws from for the utility model time-delay.

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. 2, the structural representation of the slide block mechanism that withdraws from for the utility model time-delay.The son of going into of the slide block mechanism that this time-delay is withdrawed from is gone into son 101 and second by first and is gone into son and 102 be formed by stacking successively, this first is gone into son 101 and second goes into sub 102 end faces and offer the Angle Pin hole of running through 103 respectively with this, 104, this second goes into the diameter in the Angle Pin hole 104 of son on 102 greater than this first diameter of going into the Angle Pin hole 103 on the son 101, this Angle Pin 105 is arranged in first and goes into the Angle Pin hole 103 that son 101 and second is gone into son 102, in 104, and second go in son 102 the Angle Pin hole 104 to have an empty avoiding distance at this, this second is gone into sub 102 end faces and is provided with backstop screw 106, first go into son 101 movement position to limit this, this second is gone into sub 102 bottoms and also is provided with wear-resistant block 108.

Bundle piece 107 is located at first and is gone into the end that son 101 and second is gone into son 102, and be fixed in the caster 109 of mould with screw 110, during matched moulds, this bundle piece 107 is gone into son 101 and second with first and is gone into sub 102 and tighten, prevent that this from first going into son 101 and second go into after son 102 is subjected to injection pressure with this, and retreat.

See also Fig. 3 and Fig. 4, withdraw from the action schematic diagram and withdraw from the action schematic diagram for the second time the first time of the slide block mechanism that withdraws from for the utility model time-delay.When mould is opened, be fixed in bundle piece 107 on the caster 109 with Angle Pin 105 along with this caster 109 moves upward, the Angle Pin hole 103 that this Angle Pin 105 and first is gone on the son 101 is in the close-fitting state, and go in son 102 the Angle Pin hole 104 to have an empty avoiding distance second, therefore this Angle Pin 105 is when moving upward, can stir this and first go into son and 101 retreat, make this first front end of going into son 101 break away from product 10.

When first go into the son 101 withdraw from product 10 fully after, the empty avoiding distance that Angle Pin 105 has moved and gone in son 102 the Angle Pin hole 104 second, second go into son and 102 contact with this, at this moment, Angle Pin 105 continues to move upward, and stir this and second go into son and 102 withdraw from product 10, the integral body of finishing slide block withdraws from.Wherein, this Angle Pin 105 drives first goes into son 101 and second to go into the motion principle of principles that son 102 moves and traditional slide block mechanism consistent, therefore, just no longer gives unnecessary details at this.

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.
