The molding component 2 includes the target product syringe body 202. However, the syringe body 202 is also connected to the flow diversion residue 204, the flow choking residue 203 and the injection residue 201 formed by the hot runner. The demolding rod 110 includes a guide post 111 that is inserted into the movable plate of the syringe mold 1. The end of the guide post 111 has a molding post 112.

[0036] The X guide rail 501 is movably connected with a lifting assembly 6, the whole lifting assembly 6 extends along the vertical direction, for realizing a lifting movement, the specific structure of the lifting assembly 6 comprises a sleeve 602 which is slidably connected with the X guide rail 501, the X guide rail 501 is provided with a through side sliding groove 502, and the outer side of the sleeve 602 is fixedly connected with a sliding block 606 which is matched with the sliding groove 502 to form a sliding pair and can slide along the horizontal direction perpendicular to the Y guide rail 8, the outer side of the X guide rail 501 is fixedly connected with a transverse telescopic device 505 for driving the sleeve 602 to slide relative to the X guide rail 501, the side of the sliding block 606 which is located outside the sliding groove 502 is provided with an ear plate 607, that is, the ear plate 607 extends outside the X guide rail 501, the transverse telescopic device 505 is a pneumatic cylinder, the movable end of the pneumatic cylinder is connected with the ear plate 607, so as to drive the sliding block 606 to slide relative to the sliding groove 502, the sleeve 602 is inserted with a telescopic rod 601, the telescopic rod 601 and the sleeve 602 can form a structure which can be stretched and contracted, but in the embodiment, an additional driving structure is used to realize the function, specifically: the side of the telescopic rod 601 which extends outside the sleeve 602 is provided with a traction plate 604, the outer side of the sleeve 602 is fixedly connected with a longitudinal telescopic device 605 which is also a pneumatic cylinder, the movable end of the pneumatic cylinder is connected with the traction plate 604, and the movable end of the pneumatic cylinder can drive the telescopic rod 601 to be inserted or extended relative to the sleeve 602 when the pneumatic cylinder is telescoped, compared with the structure that the telescopic rod 601 and the sleeve 602 directly form a pneumatic cylinder, the additional pneumatic cylinder structure can not only improve the stability of the movement of the telescopic rod 601 relative to the sleeve 602, but also effectively reduce the energy consumption, because the sleeve 602 has a large volume but does not need to be filled with gas inside, the telescopic rod 601 is not heavy even under full load working condition, so it can work normally without a large lifting power, and the longitudinal telescopic device 605 as a driving component is set to be small, which is naturally beneficial to energy saving.

[0037] The lower end of the telescopic rod 601 is provided with a stripping assembly 7 which extends into the needle cylinder mold 1 in the mold opening state to take out the forming assembly 2. After stripping, the forming assembly 2 is not dropped downward, but is lifted upward. The specific structure of the stripping assembly 7 comprises a pair of packaging plates 702 fixedly connected with the telescopic rod 601 for mounting moving parts. The stripping assembly 7 further comprises a cantilever rod 703 fixedly connected between the packaging plates 702, so that the packaging plates 702 are away from the lifting assembly 6. The upper end of the cantilever rod 703 is provided with a connecting plate 704, and the lower end of the telescopic rod 601 is provided with a suspension plate 603.

The second drive 705 also comprises a servo motor and a speed reduction structure inside, for driving the oscillating gear 706 to rotate within a certain angle range, usually within a 90° range. The two ends of the oscillating gear 706 are provided with coaxial end shafts 707 for respectively cooperating with the two packaging plates 702 to form a rotating pair, limiting the movement freedom of the oscillating gear 706. The side surface of the oscillating gear 706 is fixedly connected with a stripping plate 709. Actually, the oscillating gear 706 is fixedly connected with the stripping plate 709 through the side linkage plate 708. The stripping plate 709 directly contacts with the forming assembly 2. The two packaging plates 702 are further fixedly connected with a limiting plate 701 for limiting the rotation angle of the stripping plate 709. Actually, the stripping plate 709 can only move within the vertical and rear horizontal angle ranges under the blocking action of the packaging plates 702 and the limiting plate 701.

[0038] The sleeve plate 709 is provided with a center hole 711 and a plurality of needle cylinder holes 712, wherein the center hole 711 is used for the injection residual part 201 to pass through, the number and position of the needle cylinder holes 712 correspond to the needle cylinder bodies 202 in the formed assembly 2, each needle cylinder body 202 passes through a needle cylinder hole 712 and is hung in the needle cylinder hole 712 in an inclined state, the sleeve plate 709 is provided with an annular air bag 710 at the end of the center hole 711, the annular air bag 710 is supported by rubber material which is good in elasticity and wear resistance, can reduce or expand the body volume to a certain extent, the injection residual part 201 will pass through the center ring of the annular air bag 710 and is in close contact with the inner wall of the annular air bag 710 when the annular air bag 710 is inflated, the back of the sleeve plate 709 is fixedly connected with a constraint ring 713, the back of the sleeve plate 709 is actually the side of the needle cylinder wing of the end of the needle cylinder body 202, the end of the constraint ring 713 away from the sleeve plate 709 is fixedly connected with a contraction cover 714, the center of the contraction cover 714 is still provided with a hole for the longest injection residual part 201 to pass through, the annular air bag 710 is located in the space surrounded by the constraint ring 713 and the contraction cover 714 and is displaced, the annular air bag 710 is connected with an air pipe 715, the annular air bag 710 communicates with a gas pump part through the air pipe 715, the air pipe 715 communicates with the annular air bag 710 to realize air supply and exhaust of the annular air bag 710, the air pipe 715 can inflate the annular air bag 710 to expand and thus tighten the injection residual part 201, or can deflate the annular air bag 710 to shrink and thus release the injection residual part 201, so that the whole residual part is separated from the sleeve plate 709.

[0039] Working principle: Before the mold separation device operates, the syringe mold 1 first separates, exposing the molding component 2 fitted on the molding post 112. Then, the ejector component 7 located above the syringe mold 1 descends under the action of the lifting component 6, aligning the center hole 711 on the vertical sleeve plate 709 with the injection residue 201 and the syringe hole 712 with the syringe body 202. Then, the first drive 504 drives the lifting component 6, allowing the sleeve plate 709 to approach the molding component 2, which is still fitted on the ejector rod 110, from the end of the injection residue 201 until most of the injection residue 201 and the syringe body 202 pass through the corresponding holes. Then, the molding post 112 retracts under the action of the guide rod 111, and the molding component 2... The syringe body 202 is held in place by the baffle inside the syringe mold 1. After losing the support of the molding column 112, the weight of the syringe body 202 in front of and behind the sleeve plate 709 will become unbalanced. Under its own gravity, the syringe body 202 will deflect about the inner bottom wall of the syringe hole 712. Since the connection between the syringe body 202 and the diversion residue 204 is very weak, the syringe body 202 will almost instantly break away from the diversion residue 204 the moment it loses the support of the molding column 112. It will then hang on the sleeve plate 709 in an inclined state relative to the sleeve plate 709 under the constraint of its own tail syringe wing. The connection area between the injection residue 201 and the main residue 203 is very large, so even if the force is uneven, It will not break, but will form a whole piece of scrap material consisting of the water injection residue, the main flow residue 203, and the diversion residue 204 connected together. The injection residue 201, constrained by the inflated annular air bladder 710, is restricted on the sleeve plate 709. In this state, it moves upward with the sleeve plate 709 away from the internal space of the syringe mold 1, and then moves along the Y guide rail 8 away from the top of the syringe mold 1, moving above the material box where the syringe body 202 is placed. The sleeve plate 709 changes from a vertical state to a horizontal state under the action of the second drive 705. Since the syringe body 202 is not subject to additional constraint, it will fall off the sleeve plate 709 during the tilting process, while the injection residue constrained by the annular air bladder 710... The residual part 201, which connects the main residual part 203 and the diversion residual part 204, will not fall off the bushing plate 709. Finally, the bushing plate 709 moves a distance away from the syringe mold 1 along the Y guide rail 8 to the material box above the waste material. The air pipe 715 extracts the gas from the annular air bag 710, causing the air bag to contract. The constraint on the injection residual part 201 disappears, and it will separate from the bushing plate 709 under its own gravity. After all the molded materials are separated, the bushing plate 709 will return to the initial position directly above the syringe mold 1, waiting for the next cooled molding component 2 to continue the next round of separation. In this way, the separation of the syringe body 202, which is the main product, from the injection residual part is achieved.
