Abstract
The utility model provides a linear ejection core pulling releasing structure which can solve the technical problem that a slant ejection body can still slightly tilt during an ejector rod ejects and ensure that a product can smoothly get rid of a model and a buckle. The linear ejection core pulling releasing structure comprises a slant ejection body and a concave mold seat. The slant ejection body is arranged in a cavity of the concave mold seat and contacted in a V-shaped face mode. The ejector rod penetrates through the bottom of the concave mold seat. The upper end portion of the ejector rod is arranged in a bottom groove of the slant ejection body. The bottom of the slant ejection body is close to the bottom of the concave mold seat. The linear ejection core pulling releasing structure is characterized in that the bottom groove of the slant ejection body is T-shaped. The ejection rod body is T-shaped. The T-shaped end portion of the ejector rod is arranged in the bottom groove of the slant ejection body in a buckled mode. The bottom of the slant ejection body is arranged at half of the height of a body of the concave mold seat. The upper end face of the concave mold seat is arranged below a top end of a retaining block.
Description
Technical field
The utility model relates to die core pulling device, is specially the straight top releasing structure of loosing core.
Background technology
after the machining formed product, will be with the smooth demoulding of the product after moulding, simultaneously often because some products have back-off, therefore also must simultaneously the back-off of product be threaded off, the device that adopts is seen domestic patent " straight top core-pulling device ", the applying date is 2010-09-30, notification number CN201833523U, but, there is defective in the technical scheme of this patent: angle ejector rod 11 is to be rotatably connected with oblique top 9 direct employings, and faying face little between angle ejector rod 11 and oblique top 9, cause the oblique top 9 of angle ejector rod 11 in the jack-up process easily to occur crooked, the final smooth demoulding and the dropout that affects product (seen Fig. 1, in Fig. 1, 1 is die socket, 3 is block, 5 is T-shaped oblique top pin, 7 is spring).We improve for defects, and the bottom groove of oblique top body is set to T-shaped, and the push rod body is made as T-shaped, and the T-shaped end spiral-lock of push rod body is in the bottom groove of oblique top body.Yet this improvement because the length of combination between push rod and oblique top body is shorter, causes the stroke of push rod jack-up longer, and push rod is after jack-up one segment distance, and the oblique top body breaks away from die socket, can occur still that a little is crooked; And the upper surface of die socket is positioned at again the top on the top of block, the distance that causes block to move is also longer, and the upper half part of block must move to the upper surface that exceeds die socket, block could rotate, to give T-shaped oblique top pin thrust, realize " loosing core ", " dropout " under the rebound effect of spring, therefore, the structure after improvement still can have influence on the smooth demoulding of product and thread off.
Summary of the invention
For the problems referred to above, the utility model provides a kind of straight top releasing structure of loosing core, and can solve push rod oblique top body in the jack-up process and a little crooked technical problem still occur, and can guarantee the smooth demoulding of product and thread off.
its technical scheme is such, it comprises the oblique top body, die socket, described oblique top body is placed in the die cavity of described die socket, V-shaped contact, push rod is through the bottom of described die socket, its upper-end part of driving is in the bottom groove of described oblique top body, the bottom of described oblique top body is close to the bottom of described die socket, block is flexibly connected by pin and described oblique top body, it is characterized in that: the bottom groove of described oblique top body is set to T-shaped, described push rod body is T-shaped, the T-shaped end spiral-lock of described push rod body is in the bottom groove of described oblique top body, the bottom of described oblique top body is positioned at half height of the body of described die socket, the upper surface of described die socket is positioned at the below on the top of described block.
It is further characterized in that: 1/3rd position down to the body height of described block is played on the top that the upper surface of described die socket is positioned at described block.
in said structure of the present utility model, it is no longer direct movable the connection between push rod and oblique top body, but pass through its T-shaped end spiral-lock in the oblique top body, the oblique top body is difficult for rocking after being broken away from die socket by jack-up, be positioned at simultaneously half height of the body of die socket due to the bottom of oblique top body, the upper surface of die socket is positioned at the below on the top of block, like this, lengthened on the one hand the length of combination between push rod and oblique top body, on the other hand, as long as block is mobile shorter distance, just can occur rotating, the ejection stroke of push rod has shortened, guaranteed the smooth demoulding of product and threaded off.And further, a position of/3rd down to the body height of block is played on the top that the upper surface of die socket is positioned at block, through overtesting, the block in the vertical direction only will move the sixth of its body height like this, rotating can appear in the center of just having crossed its body, make the stroke of push rod jack-up greatly shorten, be also that the distance that the oblique top body ejects shortens greatly, crooked phenomenon occurs after further effectively having avoided the oblique top body to eject a segment distance, can guarantee the smooth demoulding of product and thread off.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
see Fig. 2, the utility model comprises oblique top body 9, die socket 1, oblique top body 9 is placed in the die cavity 11 of die socket 1, V-shaped contact, be provided with oblique top deep gouge 6 on oblique top body 9 bodies, T shape oblique top pin 5 passes through spring 7 spiral-locks in oblique top deep gouge 6, block 3 is flexibly connected by pin 4 and oblique top body 9, one end in contact of block 3 and T shape oblique top pin 5, the bottom groove 12 of oblique top body 9 is set to T-shaped, push rod 2 bodies are T-shaped, the T-shaped end spiral-lock of push rod 2 bodies is in the bottom groove 12 of oblique top body 9, push rod 2 bodies are through the bottom of die socket 1, coordinate with the bottom gap of die socket 1, the bottom 13 of oblique top body 9 is positioned at half height of die socket 1, the upper surface 1-1 of die socket 1 is positioned at the below of the top 3-1 of block 3, the top 3-1 that the upper surface 1-1 of die socket 1 is positioned at block 3 plays 1/3rd position 3-2 down to the body height of block 3.In figure, 8 is product.
