Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of injection mold with the bullet anti-sticking to mould of needle,
Including rear cavity 1, the interior surface of 1 side of rear cavity, which runs through, offers the first fixed card slot 8,8 surface card of the first fixed card slot
Equipped with angle ejector rod 2, divide inside angle ejector rod 2 and close to the position in the middle part of it through sliding channel 7,7 both ends of sliding channel are offered
Not Guan Chuan 2 both side surface of angle ejector rod, 7 surface of sliding channel and offer the second fixed card slot 6 close to one end of rear cavity 1, the
Two fixed card slots, 6 inner cavity, which is provided with, plays needle 3, plays the both ends of needle 3 through the second fixed card slot 6 and extends to the second fixed card slot 6
Outside, the overall length for playing needle 3 are greater than the overall length of sliding channel 7, therefore after being separated from each other between front cavity 5 and rear cavity 1, play needle 3
It is no longer influenced by the pressure from front cavity 5 and springs back, play needle 3 at this time close to one end of front cavity 5 by 7 bullet of sliding channel
Out, so as to pop up injection molding product 4 by 1 surface of rear cavity, to realize demoulding.3 appearance of needle is played similar in horizontal
Font, and the maximum width for playing needle 3 is greater than the width of sliding channel 7, when bullet needle 3 is no longer influenced by the pressure of front cavity 5 and occurs
Rebound, so as to drive the entire needle 3 that plays constantly to move along sliding channel 7 to 5 direction of front cavity, when the maximum for playing needle 3 is wide
When being moved to the intersection of the second fixed card slot 6 and sliding channel 7 at degree, then played at this time using 7 pairs of bullet needles 3 of sliding channel
Position-limiting action prevents it from passing through sliding channel 7 to being detached from angle ejector rod 2, so as to will play that needle 3 is fixed on inside angle ejector rod 2 the
Two fixed card slots 6 are in case reuse.The surface of 1 protruding parts of rear cavity is fitted with injection molding product 4, injection molding product
4 side surfaces far from rear cavity 1 are fitted with front cavity 5, and 1 appearance of rear cavity is similar to convex, and 5 appearance of front cavity is similar to character cut in bas-relief
Type, the two are used cooperatively, and injection molding product 4 is fastened between 1 adjacent surface of front cavity 5 and rear cavity, the protrusion of rear cavity 1
Shape and angle ejector rod 2 at position and side surface edge placement far from angle ejector rod 2 is close to 4 one side surface of injection molding product
Shape at edge placement is identical, thus may make injection molding product 4 both side surface can respectively with front cavity 5, rear cavity 1
And seamless applying contact between angle ejector rod 2, to guarantee that obtained 4 specification standards of injection molding product are unified.Whole device knot
Structure is simple, slightly improves on the basis of original demoulding, can easily be demoulded to the injecting products of various elasticity, operation side
Just, and be conducive to improve whole working efficiency and advantageously reduce whole production cost.
In use, can first remove front cavity 5 by 1 surface of rear cavity when needing demoulding, then the two is mutually divided at this time
From, and play needle 3 at this time and be no longer influenced by the pressure from front cavity 5 and spring back, so as to drive the entire needle 3 that plays constantly along cunning
Dynamic channel 7 is mobile to 5 direction of front cavity, when the maximum width for playing needle 3 is moved to the second fixed card slot 6 and slides logical
When the intersection in road 7, at this time then using 7 pairs of bullet needles 3 of sliding channel play position-limiting action prevent its pass through sliding channel 7 to
It is detached from angle ejector rod 2, so as to play the second fixed card slot 6 that needle 3 is fixed on angle ejector rod 2 inside in case of reuse, bullet at this time
Needle 3 is popped up close to one end of front cavity 5 by sliding channel 7, so as to generate thrust to injection molding product 4 and by injection molding
Product 4 is popped up by 1 surface of rear cavity, to realize demoulding, whole device structure is simple, slightly changes on the basis of original demoulding
