Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] As shown in the figure, the embodiment of the present invention discloses a mold ejection mechanism with a protection device, including a main mold shell 1, a main mold core 2, a nitrogen spring 3, a plum blossom punch 4, an ejector back pad 5, and a lock cover 6. Main mold cavity back pad 7, thimble protective cover 8, thimble 9 and main mold thimble sleeve 10, one end of nitrogen spring 3 is installed on main mold core 2, and the other end of ...

The invention discloses a mould ejecting-out mechanism with a protection device. The mould ejecting-out mechanism comprises a main mould case, a main mould core, a nitrogen gas spring, a plum blossomshaped punch needle, an ejector pin rear cushion, a locking tooth cover, a main mould cavity rear cushion, an ejector pin protective sleeve, an ejector pin and a main mould ejector pin sleeve, whereinone end of the nitrogen gas spring is mounted on the main mould core; the other end of the nitrogen gas spring is mounted on the ejector pin rear cushion; the locking tooth cover is mounted between the ejector pin rear cushion and the main mould cavity rear cushion; one end of the ejector pin is mounted on the main mould ejector pin sleeve; the ejector pin passes through the center of the main mould cavity rear cushion, the center of the locking tooth cover and the center of the ejector pin rear cushion until one end of the main mould core; the plum blossom shaped punch needle is arranged onthe middle part of the nitrogen gas spring; the main mould case is arranged outside the main mould core, the nitrogen gas spring, the ejector pin rear cushion and the locking tooth cover; and the ejector pin passes through the ejector pin protective sleeve. The main mould cavity rear cushion and the ejector pin protective sleeve are designed, so that single or multiple ejector pins are kept on existing center positions on the same axis all the time, and therefore, ejector rod bending and breaking caused by suspending for a too long time during ejecting-out are avoided.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a mold ejection mechanism with a protection device. Background technique [0002] In the case of the existing mold length, the longer the processed product, the longer the ejector rod hangs behind the mold, the greater the force when ejecting, and then the ejector rod will bend and break, causing mold damage. Make product ejection invalid. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a mold ejection mechanism with a protective device to solve the problem of bending and bending of single or multiple combined ejector pins during ejection, so that the ejector pins are more stable, stable, and Not easy to break. [0004] The embodiment of the present invention discloses a mold ejection mechanism with a protection device, including a main mold shell, a main mold core, a nitrogen spring, a plum blossom punching needle, a thimble...
