• (1) in der Verriegelungsvorrichtung wird nur der Hydraulikzylinder verwendet, um die Form zu verriegeln, und es gibt nur zwei Einzelbewegungen - Vorwärtsbewegung und Rückwärtsbewegung, der Hydraulikzylinder kann die Formschließposition nicht genau lokalisieren, was dazu führt, dass die Verriegelungsposition ungenau ist und die Klemmwirkung nicht gut ist, was die stabile Einspritzung mit starkem Einspritzdruck beeinträchtigt;
• (2) bei der Einspritzvorrichtung ist der Niederdrückmechanismus mit dem Einspritzplunger des Einspritzmechanismus starr verbunden, dabei ist nicht nur die mechanische Struktur leicht zu beschädigen, sondern es ist auch nicht bekannt, wann beim Einspritzen der Formhohlraum voll gefüllt ist, nämlich ist der Zeitpunkt der vollen Befüllung des Formhohlraums nicht bekannt ist; gleichzeitig kann es nicht gewährleistet werden, dass der Hub des Abwärtsdrucks den Formhohlraum voll füllen kann; dadurch wird der Grad der Fertigstellung des Einspritzens verringert;
• (3) wenn die Einspritzvorrichtung die hin- und hergehenden Niederdrück- und Hochziehvorgängen durchführt, um den Einspritzvorgang abzuschließen, wird eine große Wärmemenge erzeugt und die Temperatur ist sehr hoch, diese Wärme wird nach oben auf den Antriebsmechanismus übertragen, was einen großen Einfluss auf die Arbeit des Antriebsmechanismus hat und nicht förderlich für den langfristigen normalen Betrieb des Antriebsmechanismus ist;
• (4) in der Materialkammer der Einspritzvorrichtung ist der Kolben zum Ansteuern des Vorschubs eine einfache Kolbenstruktur, die nur eine geneigte Fläche aufweist und sich ohne Führungsstruktur vollständig durch Luftdruck auf und ab bewegt, wodurch der Kolben sich leicht nach links und rechts während der Aufwärts- und Abwärtsbewegung verschieben kann und anfällig für ein unstabiles Phänomen ist; gleichzeitig wird die Zufuhröffnung nur durch die geneigte Fläche blockiert, was zu einer schlechten Stabilität führt;
• (5) bei der Installation der Einspritzvorrichtung wird die Position manuell kalibriert; jedes Mal, wenn die Einspritzvorrichtung zu ersetzen ist, soll die Einspritzvorrichtung erneut manuell installiert und positioniert werden, was zeitaufwendig und mühsam ist, und die Installation und Positionierung sind nicht genau;
• (6) die Methode des manuellen Zuführens von Materialien in den Ofen wird verwendet, aufgrund des Einflusses menschlicher Faktoren kann die Zugabe von Materialien nicht kontrolliert werden, wenn zu viel Rohmaterial hinzugefügt wird, sinkt die Temperatur im Ofen erheblich, wodurch die Stabilität der Temperatur des Ofens beeinträchtigt wird, und die Anforderungen des Metalls an die Temperatur sind sehr hoch, der Temperaturabfall beeinträchtigt unweigerlich die Qualität des fertigen Gussprodukts.

• (2) in the injection device, the depression mechanism is rigidly connected to the injection plunger of the injection mechanism, not only is the mechanical structure easy to damage, but it is also not known when the mold cavity is full during injection, namely the time of full Filling of the mold cavity is not known; at the same time, it cannot be guaranteed that the downward pressure stroke can fully fill the mold cavity; thereby reducing the degree of completion of injection;
• (3) When the injector performs the reciprocating push-down and pull-up operations to complete the injection process, a large amount of heat is generated and the temperature is very high, this heat is transferred upward to the driving mechanism, which has a great influence on the work of the drive mechanism and is not conducive to the long-term normal operation of the drive mechanism;
• (4) In the material chamber of the injector, the piston for driving the feed is a simple piston structure, which only has an inclined surface and moves up and down completely by air pressure without any guide structure, which makes the piston move slightly left and right during the upward movement. and downward movement may shift and is prone to an unstable phenomenon; at the same time, the feed port is only blocked by the inclined surface, resulting in poor stability;
• (5) When installing the injector, the position is calibrated manually; every time the injector is to be replaced, the injector is to be manually installed and positioned again, which is time-consuming and laborious, and the installation and positioning are not accurate;
• (6) the method of manually feeding materials into the furnace is used, due to the influence of human factors, the addition of materials cannot be controlled, if too much raw material is added, the temperature in the furnace will drop significantly, thereby affecting the stability of the temperature of the Furnace is affected, and the metal's temperature requirements are very high, the temperature drop will inevitably affect the quality of the finished cast product.

• a longitudinal installation plate 1;
• a mold 2 arranged at the front of the longitudinal installation plate 1; a locking device 3 comprising a plurality of locking mechanisms 31 arranged surrounding the periphery of the mold 2;
• an injector 4 disposed at the rear of the longitudinal installation plate 1, the injection nozzle 40 of the injector 4 extending into the mold 2; and wherein the injector 4 completes the injection operation after the locking mechanism 31 completes the closing operation; a PLC controller 5 electrically connected to the locking device 3 and the injection device 4, respectively;
• wherein the locking mechanism 31 comprises a locking fixing component 311 arranged on the longitudinal installation plate 1 and a hydraulic locking component 312 connected to the locking fixing component 311, and wherein the locking fixing component 311 comprises a fixing servo motor 3111 arranged on the longitudinal installation plate 1 and electrically connected to the PLC control 5, one to the Form 2 connected fixing screw 3112, a closure cap 3113 screwed to the fixing screw 3112 and a gear structure 3114 connected between the fixation servo motor 3111 and the closure cap 3113, and wherein the hydraulic locking component 312 acts on the closure cap 3113. The fixing servo motor 3111 provides a rotation driving force transmitted through the gear structure 3114 to drive the cap 3113 to rotate, then the fixing screw 3112 screwed to the cap 3113 can push the mold 2 for mold closing or mold opening operation. Specifically, the fixing servo motor 311 drives the cap 3113 to rotate forward, the fixing screw 3112 pushes forward so that the mold 2 is closed; conversely, the fixing servo motor 3111 drives the cap 3113 to rotate backwards, the fixing screw 3112 retracts so that the mold 2 is opened.

The fixing servo motor 3111 in the lock fixing component 311 is used for precisely fixing the closed position of the mold 2, not only has high accuracy, but the fixing servo motor 3111 can also perform arbitrary opening and closing operations, fixing operations, repeated operations, multi-segment fixing operations and other more complicated ones Realize opening and closing or fixing operations for different shapes, allowing more complex and diverse operations to be carried out. Then, after fixing, the mold 2 is completely and thoroughly locked by the hydraulic locking component 312, the hydraulic pressure is high and the locking stability is better. Therefore, through the combination between the lock fixing component 311 and the hydraulic lock component 312, a goal of accurate positioning and mold closure as well as thorough and stable locking can be achieved. As in 4 shown, in the present exemplary embodiment, the hydraulic locking component 312 includes a positioning seat 3121 arranged on the longitudinal installation plate 1, a hydraulic cylinder 3122 arranged on the positioning seat 3121 and electrically connected to the PLC control 5, a hydraulic cylinder 3122 arranged in the hydraulic cylinder 3122, on the closure cap 3113 and/or the fixing screw 3112 acting locking structure 3123 and a release structure 3124 arranged in the hydraulic cylinder 3122 and acting on the closure cap 3113, wherein the closure cap 3113 is arranged in the positioning seat 3121 and extends to the interior of the hydraulic cylinder 3122. After the locking fixing component 311 accurately fixes the closed position of the mold 2, the hydraulic cylinder 3122 provides a hydraulic force to push the locking structure 3123 forward, the locking structure 3123 pushes the cap 3113 and/or the fixing screw toward the mold by a small amount Stretch to absorb the deformation amount of the mechanical structure, so that the cap 3113 and the fixing screw lock the mold 2, due to high hydraulic pressure, the goal of complete thorough locking of the mold is achieved to complete the subsequent injection operations. After the finished injection, when the mold opening is needed, the force of the hydraulic cylinder 3122 disappears, then the release structure 3124 in the reverse direction pushes the cap 3113 by a small distance, so that the cap 3113 returns back to the position fixed by the lock fixing component 311, to facilitate the driving of the locking fixing component 311 in the reverse direction and to cause the closure cap 3113 to rotate in the reverse direction, in this way the fixing screw 3112 is made to retract to complete the mold opening operation of the mold 2.

In particular, the locking structure 3123 comprises a locking piston 31231 and arranged in the hydraulic cylinder 3122 and located behind the closure cap 3113 a plurality of locking springs 31232 arranged between the locking piston 31231 and the closure cap 3113. Under the hydraulic action of the hydraulic cylinder 3122, the locking piston 31231 is driven to act on the closure cap 3113, so that the closure cap 3113 moves towards the mold 2 by a small distance, to absorb the amount of deformation of the mechanical structure, so that the cap 3113 and the fixing screw lock the mold 2, thereby achieving the goal of completely thoroughly locking the mold to complete the subsequent injection operations. At the same time, the locking spring 31232 is compressed. After the finished injection, when the mold opening is needed and the hydraulic action of the hydraulic cylinder 3122 disappears, the elastic recovery force of the locking spring 31232 acts on the locking piston 31231, so that the locking piston 31231 retracts.

In particular, the release structure 3124 comprises at least one reverse thrust shaft sleeve 31241 placed on the periphery of the closure cap 3113 and a plurality of reverse thrust springs 31242 arranged between the reverse thrust shaft sleeve 31241 and the positioning seat 3121. When the locking piston 31231 drives the cap 3113 to move toward the mold 2 for a small distance, the reverse thrust spring 31242 is compressed. After the locking piston 31231 retracts during the mold opening process, the elastic restoring force of the reverse thrust spring 31242 acts on the reverse thrust shaft sleeve 31241 and the cap 3113, so that the cap 3113 retracts to the position fixed by the lock fixing component 311 to drive the lock fixing component 311 in reverse Direction to facilitate and complete the mold opening process of mold 2.

In order to exert the force on the closure cap 3113 and to realize the locking and releasing process of the closure cap 3113, an annular projection 31131 protrudes from the periphery of the closure cap 3113 in the present exemplary embodiment, with the locking structure 3123 behind the annular projection 31131 and the release structure 3124 in front the annular projection 31131 is arranged, and a bearing 3125 is arranged between the plurality of locking springs 31232 and the annular projection 31131 and between the reverse thrust shaft sleeve 31241 and the annular projection 31131, with the arrangement of the bearing 3125, the axial friction force and the radial friction force when the cap 3113 moves can be reduced to increase the movement speed and accuracy of the cap 3113.

As in 3 shown, the gear structure 3114 in the present exemplary embodiment is mainly formed by a drive wheel 31141 arranged on the output shaft of the fixation servo motor 3111, a driven wheel 31142 connected to the closure cap 3113 and a transmission belt 31143 arranged between the drive wheel 31141 and the driven wheel 31142. By a combination between the drive wheel 31141, the driven wheel 31142 and the transmission belt 31143, the rotation driving force of the fixing servo motor 3111 can be accurately transmitted to the cap 3113 to drive the cap 3113 to rotate.

As in 2 and 5 shown, the mold 2 in the present embodiment includes a mold installation base 21 arranged on the front of the longitudinal installation plate 1 and a plurality of locking slide blocks 22 arranged on the mold installation base 21 and connected to the fixing screw 3112; wherein the injection nozzle 40 passes to the front of the longitudinal installation plate 1 and is inserted between the plurality of locking slide blocks 22. The fixing screws 3112 of the plurality of locking mechanisms 31 drive the plurality of locking slide blocks 22 to move toward the injection nozzle 40 at the center position to complete the mold closing operation; conversely, the mold opening process is completed. The locking mechanisms 31 and the locking slide blocks 22 may each be provided in number of 4, arranged in a one-to-one correspondence as shown in FIG 2 shown.

As in 6 shown, the injection device 4 in the present exemplary embodiment comprises an injection mechanism 41 arranged on the back of the longitudinal installation plate 1 and a longitudinal push mechanism 42 connected to the injection mechanism 41, as in 7 shown, the longitudinal thrust mechanism 42 includes a longitudinal thrust installation base 421, a longitudinal thrust servo motor 422 arranged on the longitudinal thrust installation base 421 and electrically connected to the PLC controller 5, a drive gear 423 connected to the output shaft of the longitudinal thrust servo motor 422, a drive gear 423 arranged transversely on the longitudinal thrust installation base 421, in the drive gear 423 engaging eccentric wheel structure 424 and an eccentric wheel structure 424 arranged longitudinally on the longitudinal thrust installation base 421 connected longitudinal thrust structure 425. In particular, the injection mechanism 41 includes an oven 411, an injection installation base 412 arranged on the oven 411, an injection nozzle 40 inserted transversely into the injection installation base 412, and an injection thrust component 413 arranged in the injection installation base 412 and connected to the longitudinal thrust structure 425.

The longitudinal thrust servo motor 422 drives the drive gear 423 to rotate, namely it drives the eccentric wheel structure 424 engaging in the drive gear 423 to rotate. Under the eccentric effect of the eccentric wheel structure 424, the longitudinal thrust structure 425 is driven upwards and downwards during the rotation of the eccentric wheel structure 424, namely can the longitudinal thrust structure performs reciprocating depression and pull-up operations, which is conducive to performing stable injection operations, thereby driving the injection thrust component 413 of the injection mechanism 41 to perform the reciprocating depression and pull-up operations to pass the materials in the furnace 411 to inject the injection nozzle 40 into the mold 2 to complete the injection process. In particular, the materials in the furnace 411 can be metals such as zinc, aluminum or magnesium.

As in 7 until 9 shown, the eccentric wheel structure 424 in the present exemplary embodiment is mainly formed by a reinforcing shaft 4241 arranged on the longitudinal thrust installation base 421 and an eccentric wheel 4242 rotatably connected to the reinforcing shaft 4241 and engaging in the drive gear 423, the rotation shaft 42420 of the eccentric wheel 4242 being connected to the longitudinal thrust structure 425 is. Since the rotation shaft 42420 of the eccentric wheel 4242 deviates from the center position of the eccentric wheel 4242, when the eccentric wheel 4242 rotates around the rotation shaft 42420 as the center, the longitudinal thrust structure 425 is inevitably driven to move up and down due to the unique structure of the eccentric wheel 4242. In particular, the drive gear 423 and the eccentric gear 4242 are each a bevel gear.

Under the effect of the reinforcement of the reinforcing shaft 4241, the eccentric gear 4242 does not deviate longitudinally or transversely during rotation relative to the longitudinal thrust installation base 421, so that the eccentric gear 4242 can rotate stably under the drive of the drive gear 423 to support the longitudinal thrust structure 425 for performing the reciprocating to drive stably the resulting push-down and pull-up processes.

When the eccentric wheel 4242 rotates, the rotation shaft 42420 of the eccentric wheel 4242 rotates; when the rotation shaft 42420 rotates, the rotation shaft 42420 has both longitudinal displacement and transverse displacement. To ensure that the rotating shaft 42420 of the eccentric wheel 4242 drives the longitudinal thrust structure 425 only for longitudinal displacement without having transverse displacement, the longitudinal thrust structure 425 is optimized in the present embodiment. As in 10 shown, the longitudinal thrust structure 425 includes in particular a longitudinal thrust shaft 4251, wherein the rotation shaft 42420 of the eccentric wheel 4242 is connected to the longitudinal thrust shaft 4251 by a transverse translation structure 4252, and wherein the transverse translation structure 4252 has one arranged in the longitudinal thrust shaft 4251, on the periphery of the rotation shaft 42420 of the eccentric wheel 4242 attached linkage block 42521, and wherein a movement cavity 42510 for the lateral translation of the linkage block 42521 is formed in the longitudinal thrust shaft 4251. Through a combination between the linkage block 42521 and the movement cavity 42510 in the longitudinal thrust shaft 4251, the longitudinal displacement that occurs upon rotation of the rotary shaft 42420 of the eccentric wheel 4242 directly triggers the longitudinal thrust shaft 4251 to move longitudinally, namely the reciprocating push-down and pull-up operations carried out; and the transverse displacement that has occurred immediately triggers the linkage block 42521 for transverse translation in the movement cavity 42510 without exerting a transverse force on the longitudinal thrust shaft 4251, namely the longitudinal thrust shaft 4251 does not move transversely, in this way the longitudinal thrust shaft 4251 can maintain the reciprocating depression all the time - Carry out and pull-up operations stably.

In order to improve the stability of the lateral translation of the rotating shaft 42420 of the eccentric wheel 4242, as in 9 and 10 shown, the transverse translation structure 4252 in the present exemplary embodiment further comprises at least one translation sliding block 42522 arranged on the outside of the longitudinal thrust shaft 4251, which is connected to the linkage block 42521 and / or is placed on the periphery of the rotating shaft 42420 of the eccentric wheel 4242, wherein on the outer side edge of the Longitudinal thrust shaft 4251 at the same time at least one link 42511 is formed for the transverse translation of the translation sliding block 42522. When the rotation shaft 42420 of the eccentric wheel 4242 drives the linkage block 42521 for transverse translation in the movement cavity 42510, the rotation shaft synchronously drives the translation slide block 42522 to move in the link 42511, thereby the translation slide block 42522 and the link 42511 are combined with each other to have a function of translation guidance to educate len, in this way the stability of the transverse translation of the rotating shaft 42420 of the eccentric wheel 4242 is improved without the longitudinal thrust shaft 4251 being driven for transverse translation.

The construction of the transverse translation structure 4252 provides a lateral displacement for the rotating shaft 42420 of the eccentric wheel 4242, so that the rotating shaft 42420 of the eccentric wheel 4242 can move transversely without exerting a transverse force on the longitudinal thrust shaft 4251; only a longitudinal force is exerted, so that the longitudinal thrust shaft 4251 can carry out reciprocating push-down and pull-up processes all the time.

When the longitudinal thrust mechanism 42 drives the injection mechanism 41 to inject to increase the injection pressure and reduce the damage to the mechanical structure, as shown in 11 shown, the longitudinal thrust structure 425 in the present exemplary embodiment further comprises a buffer thrust shaft 4253 connected to the upper end of the injection thrust component 413, a cavity 42512 being formed in the longitudinal thrust shaft 4251, and wherein the upper end of the buffer thrust shaft 4253 is movably inserted into the cavity 42512, and wherein the buffer thrust shaft 4253 seals the cavity 42512, and wherein the interior of the cavity 42512 above the buffer thrust shaft 4253 is filled with nitrogen or inert gas. When the longitudinal thrust shaft 4251 moves downward (depresses), since the buffer thrust shaft 4253 is movably connected to the longitudinal thrust shaft 4251, the longitudinal thrust shaft 4251 does not exert a downward force on the buffer thrust shaft 4253, namely, the buffer thrust shaft 4253 does not move downward. Therefore, the downward movement of the longitudinal thrust wave 4251 inevitably causes the internal space of the cavity 42512 to decrease, therefore, the nitrogen or inert gas in the cavity 42512 is compressed, so that the internal air pressure of the cavity 42512 momentarily increases and acts on the buffer thrust wave 4253, in this way, the buffer thrust shaft 4253 moves downward and pushes the injection thrust component 413 downward, then the injector 40 receives a higher injection pressure. When the longitudinal thrust shaft 4251 moves upward, the internal space of the cavity 42512 inevitably increases, so that the internal air pressure of the cavity 42512 momentarily decreases, causing the buffer thrust shaft 4253 to move upward in the reverse direction to reduce the injection thrust component 413 to pull up. The above movements are constantly repeated to drive the injection thrust component 413 to move up and down to complete the injection process.

In the present embodiment, a flexible buffer thrust mechanism formed by the combination between the buffer thrust shaft 4253 and the nitrogen or inert gas filled in the cavity 42512 is used, thereby not only the injection pressure can be increased but also a buffer function can be achieved to provide a balancing force for the entire process.

In particular, since the nitrogen or an inert gas is used for buffering, the downward stroke of the longitudinal thrust shaft 4251 can be increased in advance. After increasing the downward stroke, not only can the internal air pressure in the cavity 42512 be increased to increase the injection pressure, but it can ensure that the mold cavity is fully filled. After the mold cavity is fully filled, the buffer thrust shaft 4253 can automatically move up or backward under the buffering effect of the nitrogen or inert gas to balance the upward and downward moving force of the buffer thrust shaft 4253, thereby no blocking phenomenon will occur. This can ensure that the mold cavity is already full and saturated, and the problem of undersaturation is not caused due to the action accuracy error or stroke error.

As in 12 and 13 shown, in the present embodiment, the injection thrust component 413 includes a feed rod 4131 arranged in the injection installation base 412 and extending to the lower end surface of the injection installation base 412, an injection plunger 4132 connected to the longitudinal thrust structure 425 and inserted into the feed rod 4131, and an injection plunger 4132 movably arranged in the feed rod 4131 , below the injection plunger 4132, feed piston 4133, wherein in the feed rod 4131 a material chamber 41310, which passes through the upper end surface and the lower end surface of the feed rod 4131, is formed, and wherein the injection plunger 4132 and the feed piston 4133 are each movable into the material chamber 41310 are introduced; and wherein the material chamber 41310 is connected to the injection nozzle 40, in particular, a passage 4120 is provided in the injection installation base 412 to connect the material chamber 41310 and the injection nozzle 40 to each other, as shown in FIG 12 shown.

In particular, the material chamber 41310 is mainly formed by connecting an upper material chamber 413101 and a lower material chamber 413102; wherein the feed piston 4133 is mainly driven by a material locking member 41331 moving in the upper material chamber 413101 and a lower one At the end of the material blocking part 41331, a guide column 41332 is formed which moves in the lower material chamber 413102, and an inner adjacent inclined surface 413311 is formed on the outer surface of the material blocking part 41331, and in which one is formed on an inner wall of the upper material chamber 413101 facing the lower material chamber 413102 the inner adjacent inclined surface 413311 coordinated outer adjacent inclined surface 4131011 is formed. As in 14 and 15 shown, three planes 413321 are formed on the outer side surface of the guide column 41332, which extend along the length direction of the guide column 41332, an edge 413322 being formed between every two planes 413321, which is in contact with the inner wall of the lower material chamber 413102, and wherein the cross section of the guide column 41332 is triangular; and wherein the guide column 41332 divides the lower material chamber 413102 into three feed channels 413321.

When the injection plunger 4132 is pushed by the longitudinal thrust structure 415 to move downward, the air pressure in the upper material chamber 413101 between the injection plunger 4132 and the feed piston 4133 increases, thus the internal air pressure depresses the feed piston 4133 so that the feed piston 4133 moves downward, until the inner adjacent inclined surface 413311 of the material blocking part 41331 and the outer adjacent inclined surface 4131011 of the upper material chamber 413101 are sealed against one another, namely the material blocking part 41331 blocks the feed opening between the upper material chamber 413101 and the lower material chamber 413102, so that the materials in the oven 411 do not enter through the lower material chamber 413102. At the same time, under the action of the downward movement of the injection plunger 4132, the materials in the upper material chamber 413101 are passed through the passage 4120 and injected outward from the injection nozzle 40 to complete the injection process in the mold 2. When the injection plunger 4132 is driven upward by the longitudinal thrust structure 425, the feed piston 4133 moves upward under the action of the vacuum pressure inside the upper material chamber 413101, then the feed port between the upper material chamber 413101 and the lower material chamber 413102 is changed from the blocked state to the switched to open state; Under the action of the vacuum pressure inside the upper material chamber 413101, the materials in the oven 411 are sucked into the upper material chamber 413101 through the three feed channels 413321 to complete the feeding process.

From this, it can be seen that the guide column 41332 achieves a guiding function for the up and down movement of the feed piston 4133 to improve the stability of the up and down movement of the feed piston 4133, moreover, it is conducive to the inner abutting slope surface 413311 of the Material locking part 41331 fits more smoothly and stably with the outer adjacent inclined surface 4131011 of the upper material chamber 413101.
