Abstract

The utility model discloses an improved structure of a half slider, which mainly consists of a left large slider, a right larger slider, a left inclined guide column, a right inclined guide column, a small slider, a small inclined guide column and a wedge. The left large slider is opposite to the right large slider, a guide column hole on the left large slider is slidably sleeved on the left inclined guide column, an avoidance gap is formed between the guide column hole of the left large slider and the left inclined guide column, the right large slider is slidably sleeved on the right inclined guide column, the small slider is mounted on the left large slider, a small loose core on the small slider extends into a cavity, and the small inclined guide column and the wedge are mounted on the right large slider. As the small slider is mounted in the left large slider, and the avoidance gap is designed between the guide column hole on the left large slider and the left inclined guide column, delay effect that the small slider moves before the large sliders is realized, by the aid of the delay structure, the small slider in the slider realizes core loosing at first, and accordingly the improved structure of a half slider has the advantages that core loosing action is more stable and reliable.

Description

The improvement structure of half-split slide

Technical field

The utility model relates to a kind of mould of plastics, particularly relates to a kind of improvement structure of half-split slide.

Background technology

Present injecting products structural design becomes increasingly complex, the hole or the groove that in product, have different directions, this just requires injection mold must need two or more directions to loose core in same slide block could the demoulding, and two directions of loosing core of product that have reach 90 degree that reach that angle has most, under the bigger situation of output, need the safe and reliable core-pulling mechanism of structure action to finish the demoulding.

The utility model content

The purpose of this utility model is to provide a kind of improvement structure of stable, the reliable half-split slide of action of loosing core.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of improvement structure of half-split slide, and it mainly is made up of the big slide block in a left side, right big slide block, left Angle Pin, right Angle Pin, small slide block, little Angle Pin, voussoir; The big slide block in the big slide block in a described left side and the right side is oppositely arranged and their faying face is the die joint of mould; Guide pillar hole on the big slide block in a described left side slidably is socketed between guide pillar hole and the left Angle Pin on the big slide block of a left Angle Pin and a left side has one section empty avoiding gap, and the big slide block in the described right side is slidably on the Angle Pin of the socket right side; Described small slide block is installed on the big slide block in a left side and loosing core for a short time on the small slide block stretched into die cavity; Described little Angle Pin and voussoir are installed on the right big slide block, and during matched moulds, and little Angle Pin slidably is located in the guide pillar hole on the small slide block, but the voussoir roof pressure is in the outside of small slide block.

The moving direction of described small slide block and die sinking direction are an angle of 90 degrees.

After adopting such scheme, because the utility model is installed in small slide block in the big slide block, realized that two kinds of differences direction of loosing core is combined on the same group of slide block, and between guide pillar hole on the big slide block in a left side and left Angle Pin the design one section empty avoiding gap, play the delayed-action behind earlier moving, the big slide block of small slide block, utilize this delay structure to allow the small slide block in the slide block loose core earlier, compare, avoided spring to do the problem of inefficacy of a specified duration with the mechanism that traditional spring is loosed core oblique top.The action of loosing core that this pure machinery is loosed core is more stable, reliable, has very big promotion prospect.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is the axonometric drawing of the big slide block in the utility model left side.

The specific embodiment

As shown in Figure 1, the utility model is a kind of improvement structure of half-split slide, and it mainly is made up of the big slide block 1 in a left side, right big slide block 2, left Angle Pin 3, right Angle Pin 4, small slide block 5, little Angle Pin 6, voussoir 7.

The big slide block 2 of the big slide block 1 in a described left side and the right side is oppositely arranged and their faying face is the die joint of mould.Guide pillar hole 11 on the big slide block 1 in a described left side slidably is socketed between guide pillar hole 11 on the big slide block 1 of a left Angle Pin 3 and a left side and the left Angle Pin 3 has one section empty avoiding gap L.Guide pillar hole 21 on the big slide block 2 in the described right side is slidably on the right Angle Pin 4 of socket.

Described small slide block 5 slips loosing core for a short time in the chute 12 of the big slide block 1 in a left side and on the

small slide block

5 and 51 stretches into die cavity 8; Described little Angle Pin 6 and voussoir 7 are installed on the right big slide block 2.When matched moulds, little Angle Pin 6 slidably is located in the guide pillar hole 52 on the small slide block 5, but voussoir 7 roof pressures are in the outside of small slide block 5.The moving direction of described small slide block 5 and die sinking direction are an angle of 90 degrees.

Operation principle of the present utility model:

During die sinking, utilize the delay structure to make the big slide block 1 in a left side that keeps small slide block 5 on one side earlier not as shown in Figure 2 from product 10() action of loosing core, and the right big slide block 2 of another side does not postpone, and directly looses core under the effect of right Angle Pin 4 and the little Angle Pin 6 that drives small slide block 5 makes small slide block 5 also loose core simultaneously (stroke 11.5mm).Postponing to finish back continuation die sinking makes the left and right

big slide block

1,2 on both sides finish the action of loosing core (stroke 70mm).

Emphasis of the present utility model just is: two kinds of different qualities are loosed core to be combined on the same group of slide block.

The above, it only is the utility model preferred embodiment, the gap can be decided according to loosing core distance between guide pillar hole on the big slide block in a left side and the left Angle Pin, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1. the improvement structure of a half-split slide is characterized in that: it mainly is made up of the big slide block in a left side, right big slide block, left Angle Pin, right Angle Pin, small slide block, little Angle Pin, voussoir; The big slide block in the big slide block in a described left side and the right side is oppositely arranged and their faying face is the die joint of mould; Guide pillar hole on the big slide block in a described left side slidably is socketed between guide pillar hole and the left Angle Pin on the big slide block of a left Angle Pin and a left side has one section empty avoiding gap, and the big slide block in the described right side is slidably on the Angle Pin of the socket right side; Described small slide block is installed on the big slide block in a left side and loosing core for a short time on the small slide block stretched into die cavity; Described little Angle Pin and voussoir are installed on the right big slide block, and during matched moulds, and little Angle Pin slidably is located in the guide pillar hole on the small slide block, but the voussoir roof pressure is in the outside of small slide block.
