Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model injection mold embodiment is described further.
A kind of injection mold, comprise cope match-plate pattern 1, punch 2, die 3, push rod 7, ejector pin retaining plate 5, push pedal 4 and lower bolster 6, described punch 2 is connected with cope match-plate pattern 1, described die 3 is suitable with punch 2, described die 3 is provided with push-rod hole 31, described push rod 7 is connected with ejector pin retaining plate 5, described push rod 7 is connected with die 3 by push-rod hole 31, described ejector pin retaining plate 5 is connected with push pedal 4, described push pedal 4 is connected with lower bolster 6, described push rod 7 comprises knock-pin 72 and roof fall bar 71, described roof fall bar 71 comprises canned paragraph 712 and active segment 711, one end of described active segment 711 is fixedly connected with ejector pin retaining plate 5, the other end is provided with the chute 7121 suitable with active segment 711, what described active segment 711 slided is positioned at chute 7121, the sidewall of described chute 7121 is provided with adjustment hole 7123 near chute 7121 back to one end place of cope match-plate pattern 1, regulating block 9 is provided with in described adjustment hole 7123, the end face of the relative canned paragraph 712 of described active segment 711 is the first inclined-plane 91 tilted towards the direction back to adjustment hole 7123, the two ends of described regulating block 9 all protrude from adjustment hole 7123, described regulating block 9 is provided with back to the side of push-rod hole 31 the second inclined-plane 7111 tilted towards cope match-plate pattern 1, opposite side and second inclined-plane 7111 of described regulating block 9 offset, described active segment 711 is provided with resetting means.
After moulding, push pedal 4 drives ejector pin retaining plate 5 to move, push pedal 4 fixed head drives knock-pin 72 to move together with roof fall bar 71, and in the process of roof fall bar 71 motion, regulating block 9 can along with moving together, along with the motion of regulating block 9, the end thereof contacts of the first inclined-plane 91 meeting lower bolster 6 relative to die 3 on regulating block 9, thus regulating block 9 is moved towards the direction of push-rod hole 31, because second inclined-plane 7111 of regulating block 9 with active segment 711 offsets, along with the continuation campaign of regulating block 9, active segment 711 can promote towards the direction away from chute 7121 by regulating block 9, thus make active segment 711 protrude from chute 7121, material is thus formed distance that workpiece ejects by roof fall bar 71 and be greater than the distance that knock-pin 72 ejects, so, shaping part will split away off from push rod 7, improve working (machining) efficiency, do not need artificial to go pickup, then push pedal 4 drives push rod 7 to reset, after push rod 7 resets, resetting means promotes active segment 711 and moves, thus regulating block 9 is moved towards the direction away from push-rod hole 31.
The degree of depth of chute 7121 is mutually identical with the length of movable end, prevents movable end be not in same plane with stiff end relative to one end of cope match-plate pattern 1 relative to one end of cope match-plate pattern 1 and affect normal injection moulding.
Described resetting means comprises limited block 10 and back-moving spring 8, the sidewall of described chute 7121 is provided with the stopper slot 7122 corresponding with limited block 10, described limited block 10 is positioned at stopper slot 7122 and limited block 10 is fixedly connected with the sidewall of active segment 711, described back-moving spring 8 is positioned at stopper slot 7122, the sidewall of one end cope match-plate pattern 1 relative to stopper slot 7122 of described back-moving spring 8 is fixedly connected with, the other end is fixedly connected with limited block 10, when injection moulding, thrust spring is in compressive state, and in the process ejected, along with the motion of active segment 711, motion in gag lever post stopper slot 7122, thus make back-moving spring 8 compress further, after by part roof fall, along with the reset of push rod 7, after push rod 7 resets, the direction of limited block 10 towards lower bolster 6 promotes by back-moving spring 8, thus regulating block 9 is moved towards the direction away from push-rod hole 31, reach the effect of reset.
The end face of the relative lower bolster 6 of regulating block 9 scribbles wear-resistant coating, described wear-resistant coating is polyether-ether-ketone coating, polyether-ether-ketone has high strength, high tenacity and high-fire resistance, its wear resistance is given prominence to, become important self-lubricating antifriction material, effectively can slow down regulating block 9 and wear and tear in the process of sliding.
