one end of the ejector rod is fixed in an ejector plate of the die;
the other end of the ejector rod pushes the straight push block, the straight push block pushes a product, a groove is formed in the straight push block, an inclined pin head of the inclined pin is arranged in the groove, and a space is reserved between the groove and the inclined pin head of the inclined pin for the inclined pin to retreat.
Optionally, the front end of the angle pin head of the angle pin extends out of the groove.
Optionally, the ejector pin vertically pushes against the straight push block.
Optionally, the top of the straight push block is provided with a step surface and a protruding surface, the protruding surface is higher than the step surface, and the step surface pushes against a product.
Optionally, the outer peripheries of the angle pin rod and the ejector rod are sleeved with wear-resistant sleeves.
Compared with the prior art, the ejection structure of the die disclosed by the invention has the advantages that when a product with an inverted buckle is ejected, the inclined pin and the straight pushing block are combined, the ejection plate of the die is ejected upwards to drive the inclined pin and the straight pushing block to perform ejection action upwards, and the inclined pin rod moves in the inclined pin seat while the straight pushing block ejects the product to move upwards, so that the inclined pin is obliquely ejected out of the inverted buckle of the product. Therefore, according to the ejection structure of the die, the straight push block decomposes the ejection pressure of the angle pin, so that the strength of the angle pin is prevented from being insufficient, ejection balance is achieved, and a product with an inverted buckle can be ejected smoothly.

[ detailed description ] embodiments
For a further understanding of the objects, technical effects and technical means of the present invention, reference will now be made in detail to the following description taken in conjunction with the accompanying drawings.
Referring to fig. 2-5, wherein fig. 2 is a schematic perspective view of the ejection structure of the mold of the present invention, fig. 3 is a schematic perspective exploded view of the ejection structure of the mold of the present invention, fig. 4 is a schematic perspective exploded view of the ejection structure of the mold of the present invention, and fig. 5 is a cross-sectional view of the ejection structure of the mold of the present invention.
In this embodiment, the ejection structure of the mold of the present invention is used for ejecting a product 10 having an undercut 11, especially a product 10 with a large area or volume, and the ejection structure of the mold includes:
an angle pin 100 having an angle pin seat (not shown), an angle pin rod 101 and an angle pin head 102, wherein the angle pin seat is a conventional angle pin seat and is fixed in an ejector plate of a mold, one end of the angle pin rod 101 is movably arranged in the angle pin seat, the other end of the angle pin rod is obliquely penetrated through a male mold plate and a male mold core of the mold, and the angle pin head 102 forms an undercut 11 of a product 10;
one end of the ejector rod 200 is fixed in an ejector plate of the die, and the ejector rod 200 plays an ejecting role;
the other end of the ejector rod 200 pushes against the straight push block 300, the straight push block 300 pushes against the product 10, a groove 301 is formed in the straight push block 300, the taper pin head 102 of the taper pin 100 is arranged in the groove 301, and a space is reserved between the groove 301 and the taper pin head 102 of the taper pin 100 for the taper pin 100 to retreat.
In another embodiment, the front end of the taper pin head 101 of the taper pin 100 can protrude from the groove 301 to precisely mold the product 10, and the straight push block 300 is prevented from being too large because the taper pin head 101 is completely disposed in the groove 301.
Wherein, the top bar 200 vertically pushes the straight push block 300, so that the straight push block 300 vertically pushes the product 10 to move upwards.
In order to enhance the strength of the straight push block 300, the top of the straight push block 300 is provided with a step surface 302 and a protruding surface 303, the protruding surface 303 is higher than the step surface 302, the protruding surface 303 is attached to a mother template of a mold, and the step surface 302 pushes against the product 10.
The outer edges of the angle pin rod 101 and the ejector rod 200 are sleeved with wear-resistant sleeves 400, so that a wear-resistant effect is achieved, and the angle pin rod 101 and the ejector rod 200 are prevented from being damaged to affect ejection of the structure.
