Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting, in particular to a lining plate production casting device. BACKGROUND

[0002] In the production of cast lining plates, resin sand manufacturing molds are a modern molding process, the core of which is to manufacture a casting mold using a mixture of silica sand and synthetic resin (such as furan resin) as a binder. Through precise mixing of raw sand, resin, and curing agent, a resin sand with good fluidity and plasticity is formed. Then, the mixture is introduced into the mold and sand box through sand shooting or sand filling, and the precise cavity profile is obtained with the help of the mold cavity. The resin rapidly undergoes cross-linking reaction and solidification under normal temperature or heating conditions, giving the sand mold sufficient strength and hardness, thereby forming a dimensionally stable, smooth-surfaced overall cavity or core. After it is completely hardened, the mold is removed, and a complete casting mold that can withstand the scouring and pressure of high-temperature metal liquid is obtained. This self-hardening sand process gives the mold excellent collapsibility, making it easy to clean the sand after the casting cools down, while ensuring that the lining plate casting has high dimensional accuracy and surface quality, effectively reducing casting defects.

[0003] A resin sand casting equipment and casting process are disclosed in Chinese patent document CN113198972B, which includes a rack, a sand mixing box, a discharge mechanism, and a second discharge mechanism. The sand mixing box is arranged on the rack, and a stirring mechanism is arranged in the sand mixing box. A discharge port is formed at the lower end of the sand mixing box, and a discharge pipe is arranged at the discharge port of the sand mixing box. The second discharge mechanism and the discharge mechanism are sequentially arranged from top to bottom at the lower end of the sand mixing box. The second discharge mechanism and the discharge mechanism facilitate the discharge of mixed resin sand in the sand mixing box into the mold. Before casting the workpiece, resin sand is first added to the sand mixing box, and the stirring mechanism in the sand mixing box is started. The stirring mechanism can stir the resin sand in the sand mixing box. The resin sand that has been stirred can be discharged from the discharge pipe of the sand mixing box. The resin sand can be discharged through the discharge mechanism and the second discharge mechanism according to the different placement positions of the mold.

[0004] In the above technology, two discharge mechanisms are arranged to discharge the resin sand in the sand mixing box into different positions in the mold. However, since the positions of the discharge ports of the two discharge mechanisms can only be adjusted along the circumferential direction of the discharge port of the sand mixing box, the resin sand discharged by the two discharge mechanisms will form two annular resin sand belts in the lower casting mold. Since the distance between the position of the discharge port of the discharge mechanism and the discharge port of the sand mixing box cannot be adjusted, the resin sand after discharging will not be evenly laid out in the casting mold. SUMMARY

[0005] The application provides a lining plate production casting device, aiming at solving the problem of uneven paving of resin sand in a casting mold after discharging due to the inability to adjust the distance between the discharging port of the discharging mechanism and the discharging port of the sand mixing box in the prior art.

[0006] The application provides a lining plate production casting device, aiming at solving the problem of uneven paving of resin sand in a casting mold after discharging due to the inability to adjust the distance between the discharging port of the discharging mechanism and the discharging port of the sand mixing box in the prior art.

[0009] The effect is that when the driving member one drives the moving frame to move laterally, the auger synchronously displaces with the moving frame, pushes the resin sand beyond the upper end of the mold to move in the left-right direction, and realizes the conveying of the resin sand in the left-right direction, the auger adopts the symmetric blade structure of two sections of blades with opposite rotation directions, can convey the resin sand beyond the upper end of the mold to the front and rear sides respectively when rotating, effectively eliminates the center accumulation phenomenon, when the moving frame moves to the left and right limit positions of the dust cover, the driving member two controls the baffles to quickly descend, the baffles away from the center of the mold are pressed downward to form a seal with the edges of the mold, prevents the resin sand from overflowing, the baffle close to the center of the mold is lifted to the upper side of the auger, avoids blocking the resin sand conveying path, and realizes the uniform distribution of the resin sand beyond the upper end of the mold in the mold cavity through the combination of lateral movement and bidirectional discharging.

The telescopic part provided at both ends of the drive rod is hinged with the baffle, when the moving frame moves transversely to the edge of the dust cover, the gear and the fixed rack meshing produces rotary power, the rotation is transmitted to the telescopic part through the drive rod, prompting the baffle to produce vertical displacement. The setting of the telescopic part allows the drive rod to produce axial displacement compensation when rotating, avoiding mechanical interference, when the moving frame reaches the right end, the gear meshes with the right end rack, the drive rod drives the right baffle to press down and contact with the mold, while the left baffle is synchronously moved up.

[0012] Preferably, a locking assembly is further provided between the moving frame and the baffle, which is used to unlock the baffle and the moving frame when the baffle abuts against the left and right ends of the dust cover, and then lock the baffle and the moving frame after the baffle abuts against the mold.

[0013] Its effect lies in: through the setting of the locking assembly, the rigid connection of the baffle and the moving frame is realized after the baffle abuts against the mold, avoiding the baffle and the upper end surface of the mold from being separated due to vibration or external force during the left and right movement of the moving frame. The locking assembly automatically triggers the locking function after the baffle completes the downward movement, so that the baffle and the moving frame form a fixed connection relationship, thereby ensuring that the baffle always maintains a close fit with the upper end surface of the mold, and ensuring that the guiding effect of the baffle on the sand flow is stable and reliable when the auger conveys the resin sand.

[0014] Preferably, the locking assembly comprises an elastic telescopic block slidingly installed on the baffle in the front-rear direction, both ends of the moving frame are provided with through holes, and both ends inside the dust cover are provided with push benches. When the baffle abuts against both ends inside the dust cover, the push benches push the elastic telescopic blocks away from the through holes.

[0015] Preferably, an elastic member one is provided between the gear and the drive rod, and an energy storage assembly is provided between the gear and the drive rod. When the gear meshes with the rack, the energy storage assembly stores energy as the moving plate moves towards both ends inside the dust cover respectively. When the elastic telescopic block is separated from the through hole, the energy storage assembly is released.

[0016] Preferably, an elastic member one is provided between the gear and the drive rod, an arc-shaped slot is provided on the drive rod, a protrusion is provided on the gear and inserted into the arc-shaped slot, and the elastic member one is an arc-shaped spring, which is arranged in the arc-shaped slot and connected with the protrusion and the drive rod at both ends.

[0017] Its effect lies in: through the cooperation of elastic piece one and arc-shaped groove, convex block, the gear rotation first carries out the elastic piece one to store the force, when the baffle is unlocked, the elastic piece one releases, thereby drives the driving rod to rotate rapidly, and then realizes the rapid lifting of the baffle, further realizes the impact of the baffle to the mold and moving plate, so that the mold, baffle and moving plate can produce vibration in the process of collision, and the resin sand adhered on the baffle and moving plate is shaken off, and the resin sand in the mold cavity is distributed more evenly when the mold vibrates.

[0018] Preferably, the lower end of the baffle is a wedge-shaped surface.

[0019] Its effect lies in: when the baffle moves downward and abuts against the upper end of the mold, the resin sand between the baffle and the mold can be pushed towards the direction of the auger through the inclined surface structure, the wedge-shaped structure can produce a guiding effect during the movement of the baffle, reducing the possibility of sand particles being stuck in the bottom of the baffle, and ensuring the smoothness of the lifting action of the baffle.

[0020] Preferably, the auger is further provided with a detection assembly for detecting the position of the resin sand, and the auger reverses rotation when the detection assembly detects that the resin sand is located at the front and rear ends.

[0021] Preferably, the detection assembly includes four pressure switches arranged on the auger, and a ring table is arranged between the two blade segments of the auger, and the four pressure switches are arranged on the front and rear ends of the two blade segments respectively, when the blade transports the resin sand to the two ends of the blade, the resin sand extrudes the pressure switch, and then the rotation direction of the auger is reversed.

[0022] Its effect lies in: by setting the detection assembly on the auger, the position distribution of the resin sand in the conveying process is monitored in real time. When the resin sand reaches the front and rear ends of the auger blade, the detection assembly triggers the auger to reverse rotation, and the two blade segments with opposite rotation directions change the conveying direction of the resin sand. The rotation direction of the auger can be dynamically adjusted according to the actual distribution of the resin sand, so as to avoid excessive accumulation or insufficient filling of the resin sand at the front and rear ends of the mold due to one-way conveying, thereby ensuring the uniform distribution of the resin sand in the mold cavity.

[0023] Preferably, the driving piece one includes a motor one arranged on the dust cover and a lead screw rotatably installed on the dust cover, the output end of the motor one is connected with the lead screw, the lead screw is arranged on the moving frame, and the lead screw is threadedly engaged with the moving frame.

[0024] Its effect lies in: through the rotation of the motor one drive screw, the use of screw and moving frame between the thread engagement relationship, the rotation of motor one is converted into the linear displacement of moving frame. This driving mode can accurately control the left and right moving position of moving frame in the dust cover, thereby adjusting the transverse position of cloth mechanism relative to the mold. Because the screw drive has self-locking characteristics, it can ensure that the moving frame stays at any position stably, avoiding the deviation caused by gravity or vibration. By adjusting the steering and speed of motor one, the reciprocating motion of moving frame in the dust cover can be realized, so that the auger can cover different areas of the mold, ensuring that the resin sand is evenly distributed in the mold.

[0025] By adopting the technical scheme, the application has the following beneficial effects:

[0026] 1. When the driving part one pushes the moving frame to move horizontally, the auger will displace synchronously with the moving frame, prompting the resin sand beyond the upper end face of the mold to move in the left and right directions, thereby realizing the conveying of the resin sand in the left and right directions. The auger adopts a symmetrical two-section blade structure with opposite rotation directions, which can push the resin sand beyond the upper end face of the mold to the front and back sides respectively during rotation, effectively eliminating the phenomenon of central accumulation. Once the moving frame reaches the left and right limit positions of the dust cover, the driving part two will control the baffle to quickly descend, away from the mold center. The baffle pressed downward and forms a seal with the edge of the mold, preventing the resin sand from overflowing. The baffle close to the mold center is lifted above the auger, avoiding obstructing the conveying path of the resin sand. Through the transverse movement and two-way distribution, the purpose of evenly distributing the resin sand beyond the upper end face of the mold in the mold cavity is achieved.

[0027] 2. With the cooperation of the elastic part one, the arc-shaped groove and the protrusion, the gear rotates first to store power in the elastic part one. After the baffle is unlocked, the elastic part one is released, and the driving rod is quickly rotated, thereby realizing the rapid lifting of the baffle. Further, the impact of the baffle on the mold and the moving plate is completed, and the mold, the baffle and the moving plate generate vibration in the collision, causing the resin sand adhered to the baffle and the moving plate to fall off. The vibration of the mold makes the resin sand in the mold cavity more evenly distributed.

[0028] 3. The detection assembly is arranged on the auger, which can monitor the position distribution of the resin sand during conveying in real time. When the resin sand is detected to reach the front and back ends of the auger blades, the detection assembly triggers the auger to rotate in the opposite direction. With the two-section blade with opposite rotation directions, the conveying direction of the resin sand is changed. In this way, the direction of the auger rotation can be dynamically adjusted according to the actual distribution condition, preventing the resin sand from accumulating excessively or not being filled enough at the front and back ends of the mold due to one-way conveying, thereby ensuring that the resin sand is evenly distributed in the mold cavity.

DETAILED DESCRIPTION

[0039] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] As Figures 1-8 shown, the liner plate production casting device of the embodiment of the present application comprises a sand mixing box 1, a dust cover 2, a moving frame 3, a driving member one 4 and a material distributing mechanism 5. The sand mixing box 1 is provided with a discharge port 11 for discharging mixed resin sand. The dust cover 2 is arranged at the discharge port 11 for preventing dust from escaping. The moving frame 3 is slidingly arranged in the dust cover 2 along the left-right direction. The driving member one 4 is used to drive the moving frame 3 to move in the dust cover 2. The material distributing mechanism 5 is arranged on the moving frame 3 and is used to respectively convey resin sand accumulated in the middle of the mold to the front and back sides, so as to avoid central accumulation.

[0041] During the casting process, the mold is first aligned with the dust cover 2 so that the mold cavity is covered by the dust cover 2. Then, the resin sand in the mixing box 1 falls into the mold cavity below through the discharge port 11. The moving frame 3 moves in the left and right direction under the drive of the drive component 4, which drives the material distribution mechanism 5 to move back and forth in the left and right direction, thereby driving the resin sand to be conveyed in the mold in the left and right direction. At the same time, the material distribution mechanism 5 conveys the resin sand back and forth in the front and back direction. By combining the left and right conveying with the front and back conveying, the resin sand in the mold cavity is evenly distributed.

[0042] like Figure 5 As shown, the movable frame 3 consists of a movable plate 31 and two mounting plates 32 disposed at the front and rear ends of the movable plate 31. The projection of the movable plate 31 and the two mounting plates 32 in the vertical direction presents an "I" shape. The lower end of the mounting plate 32 abuts against the upper end surface of the mold, and the left and right ends of the mounting plate 32 extend beyond the left and right ends of the auger 51, so that the resin sand extending beyond the upper end surface of the mold is located between the two mounting plates 32.

[0043] like Figures 2-4 As shown, the drive component 4 includes a motor 41 fixedly mounted on the dust cover 2, a lead screw 42 rotatably mounted inside the dust cover 2, and a slide rod 43 fixedly mounted inside the dust cover 2. The lead screw 42 and the slide rod 43 are located on the front and rear sides of the discharge port 11, respectively. The output end of the motor 41 is connected to the lead screw 42. The lead screw 42 and the slide rod 43 are both mounted on the moving plate 31, and the lead screw 42 is threadedly engaged with the moving plate 31. When the motor 41 rotates, it drives the lead screw 42 to move the moving plate 31 in the left and right direction inside the dust cover 2.

[0044] like Figures 2-8As shown, the cloth mechanism 5 includes an auger 51, two baffles 52 and a second driving member, the front and rear ends of the auger 51 are rotatably installed on two mounting plates 32, a motor two 512 is fixedly installed on the mounting plate 32 at the rear end of the auger 51, the output end of the motor two 512 is connected with the auger 51, the auger 51 is located directly below the moving plate 31, the rotating axis of the auger 51 extends along the front and rear directions, two sliding grooves 33 are formed on each of the two mounting plates 32, and the two sliding grooves 33 on the same mounting plate 32 are located on the left and right sides of the moving plate 31 respectively, the two baffles 52 are arranged on the left and right sides of the auger 51 respectively, and the front and rear ends of the baffle 52 are slidably installed in the sliding grooves 33 on the two mounting plates 32 along the vertical direction, the front and rear ends of the baffle 52 are fixedly installed with impact rods 53, impact holes are formed in the sliding grooves 33 on the mounting plates 32, the impact rods 53 are arranged in the impact holes, the lower end of the baffle 52 is a wedge surface, which is used to push the resin sand between the baffle 52 and the mold towards the auger 51, and the second driving member is used to drive the baffle 52 to slide along the vertical direction, the auger 51 is composed of two sections of blades with opposite rotation directions, and the two sections of blades are symmetrically arranged along the front and rear directions, when the auger 51 rotates, the resin sand accumulated in the middle of the mold can be respectively transported in the front and rear directions, avoiding the center accumulation.

[0045] When the moving frame 3 moves to the left end or the right end in the dust cover 2, the second driving member drives the baffle 52 close to the center of the mold to move upward quickly above the auger 51, avoiding blocking the resin sand conveying path, and impacting the mounting plate 32, so that the mounting plate 32 drives the moving plate 31 to vibrate, at the same time, the second driving member drives the baffle 52 on the other side to move downward quickly and impact and abut against the upper end surface of the mold, preventing the resin sand from overflowing, and ensuring that when the auger 51 moves to the other end of the dust cover 2, the baffle 52 abutting against the mold can push the resin sand to move, and the auger 51 can transport the resin sand in the front and rear directions when rotating, thereby ensuring that the resin sand is evenly laid in the mold, and when the baffle 52 impacts the mounting plate 32 and the mold, the mounting plate 32 and the mold can vibrate, at the same time, the reaction force can also make the baffle 52 vibrate, and when the baffle 52 and the mounting plate 32 vibrate, the resin sand adhered to the surface of the baffle 52 and the mounting plate 32 can be shaken off, and since the position of the baffle 52 impacting the mold is located at the left and right ends of the mold, and the depths of the left and right ends in the mold cavity are relatively deep, more resin sand needs to be filled, therefore, when the mold vibrates, the resin sand at the left and right ends in the mold cavity can be filled more densely and uniformly.

[0046] As Figures 4-8As shown, the second driving member is provided with two groups, and the two groups of second driving members are respectively arranged on the front and back of the moving plate 31. Taking the second driving member on the front side of the moving plate 31 as an example, the second driving member comprises a driving rod 54, a gear 55, two sections of the rack 21 and an energy storage assembly. The gear 55 is rotatably installed at the front end of the moving plate 31, and the driving rod 54 is rotatably installed at the front end of the gear 55. The front and back of the driving rod 54 are provided with telescopic parts 56, and the two telescopic parts 56 on the driving rod 54 are respectively hinged to the two baffles 52. The two sections of the rack 21 are respectively fixedly installed at the left and right ends in the dust cover 2. The energy storage assembly is arranged between the gear 55 and the driving rod 54. When the gear 55 rotates, the energy storage assembly is first energized. The mounting plate 32 and the baffle 52 are also provided with a locking assembly for locking the mounting plate 32 and the baffle 52, so as to avoid the deviation of the baffle 52 due to vibration when the moving frame 3 moves.

[0047] When the moving frame 3 moves right in the dust cover 2 and gradually approaches the rightmost end in the dust cover 2, the lower end of the gear 55 is engaged with the rack 21 at the right end in the dust cover 2. With the continuous movement of the moving frame 3 to the right, the gear 55 rotates relative to the driving rod 54, thereby energizing the energy storage assembly. After the baffle 52 on the right side of the auger 51 abuts against the right side wall in the dust cover 2, the mounting plate 32 and the baffle 52 are unlocked, the energy storage assembly is released, thereby driving the driving rod 54 to rotate quickly. At this time, the baffle 52 on the left side of the auger 51 moves quickly to the upper side of the auger 51, and when the baffle 52 moves to the uppermost position in the sliding groove 33, it will impact the inner wall of the sliding groove 33, thereby causing the mounting plate 32 to drive the moving plate 31 to vibrate, so as to shake off the resin sand adhered to the surface of the moving plate 31 and the baffle 52. At the same time, the baffle 52 on the right side of the auger 51 moves quickly downward and impacts the upper end face of the mold, so that the mold vibrates, thereby making the resin sand at the rightmost end in the mold cavity more dense and uniformly distributed.

[0048] When the moving frame 3 moves right in the dust cover 2 and gradually approaches the rightmost end in the dust cover 2, the lower end of the gear 55 is engaged with the rack 21 at the right end in the dust cover 2. With the continuous movement of the moving frame 3 to the right, the gear 55 rotates relative to the driving rod 54, thereby energizing the energy storage assembly. After the baffle 52 on the right side of the auger 51 abuts against the right side wall in the dust cover 2, the mounting plate 32 and the baffle 52 are unlocked, the energy storage assembly is released, thereby driving the driving rod 54 to rotate quickly. At this time, the baffle 52 on the left side of the auger 51 moves quickly to the upper side of the auger 51, and when the baffle 52 moves to the uppermost position in the sliding groove 33, it will impact the inner wall of the sliding groove 33, thereby causing the mounting plate 32 to drive the moving plate 31 to vibrate, so as to shake off the resin sand adhered to the surface of the moving plate 31 and the baffle 52. At the same time, the baffle 52 on the right side of the auger 51 moves quickly downward and impacts the upper end face of the mold, so that the mold vibrates, thereby making the resin sand at the rightmost end in the mold cavity more dense and uniformly distributed.

[0049] As Figures 4-8 shown, the locking assembly includes four elastic expansion blocks 57, two elastic expansion blocks 57 are arranged in a group, and the two groups of elastic expansion blocks 57 are arranged on the ends of the two baffles 52 away from each other in the left-right direction, the elastic expansion blocks 57 are slidingly installed on the baffles 52 in the left-right direction, the two mounting plates 32 are provided with two blocking strips 34 on the ends thereof approaching each other in the front-back direction, respectively, the two baffles 52 are located between the two blocking strips 34, and the blocking strips 34 are provided with through holes 35 penetrating through the left and right directions, respectively, when the baffles 52 are located at the uppermost end in the sliding groove 33, the elastic expansion blocks 57 are inserted into the through holes 35 from the baffles 52, thereby achieving the locking of the baffles 52 and the mounting plates 32, and the left and right ends of the dust cover 2 are provided with two push tables 22 corresponding to the through holes 35, when the baffles 52 move to the left and right ends of the dust cover 2 and abut against the left or right side wall in the dust cover 2, the push tables 22 are inserted into the through holes 35 and push the elastic expansion blocks 57 out of the through holes 35, so that the elastic expansion blocks 57 are retracted into the baffles 52, thereby achieving the unlocking of the baffles 52 and the mounting plates 32 away from the center of the mold.

[0050] As Figures 4-8 shown, the energy storage assembly includes two elastic members 58, the end surface of the driving rod 54 facing the gear 55 is provided with an arc-shaped groove, the end surface of the gear 55 facing the driving rod 54 is fixedly installed with a protrusion 59 inserted into the arc-shaped groove, the elastic member 58 is an arc-shaped spring, the spring is arranged in the arc-shaped groove, and the two springs are arranged on the left and right sides of the protrusion 59, respectively, and the two ends of the spring are fixedly connected with the protrusion 59 and the driving rod 54, respectively, when the gear 55 rotates relative to the driving rod 54, the protrusion 59 slides in the arc-shaped groove, at this time, one spring is compressed to store energy, and the other spring is stretched to store energy, when the baffles 52 are unlocked from the mounting plates 32, the two springs are released, thereby driving the driving rod 54 to rotate rapidly, thereby achieving the rapid lifting of the baffles 52, and the two baffles 52 generate impact with the mold and the moving plate 31 in the process of rapid lifting, so that the mold, the baffles 52 and the moving plate 31 vibrate.

[0051] As Figure 2 and Figure 3 shown, the auger 51 is further provided with a detection assembly for detecting the position of the resin sand, the detection assembly includes four pressure switches 511, a ring table 510 is arranged between two sections of blades on the auger 51, and the four pressure switches 511 are arranged at the front and rear ends of the blades, respectively, when the auger 51 rotates to deliver the resin sand to the front and rear ends of the blades, the resin sand presses the pressure switches 511 to trigger an electrical signal, so that the rotating direction of the motor 512 is reversed, thereby reversing the rotating direction of the auger 51, avoiding the accumulation of the resin sand at the front and rear ends of the blades, and ensuring the uniform distribution of the resin sand in the mold during the movement of the auger 51 along the left-right direction on the upper end of the mold.

[0052] The working principle of the present application is as follows:

[0053] In the casting process, the resin sand in the mixing box 1 falls into the mold through the discharge port 11, and then the motor 41 is started to drive the lead screw 42 to drive the moving plate 31 to move in the dust cover 2 along the left-right direction, and drive the auger 51 and the baffle 52 to adjust the position transversely. When the auger 51 rotates, the two sections of blades with opposite rotation directions will respectively transport the resin sand exceeding the upper end of the mold along the front-rear direction.

[0054] When the moving frame 3 moves to the right in the dust cover 2 and gradually approaches the rightmost end in the dust cover 2, the lower end of the gear 55 meshes with the rack 21 at the right end in the dust cover 2. With the continuous movement of the moving frame 3 to the right, the gear 55 rotates relative to the drive rod 54. When the gear 55 rotates relative to the drive rod 54, the protrusion 59 slides in the arc-shaped groove. At this time, the spring on the right side of the protrusion 59 is compressed to store energy, and the spring on the left side of the protrusion 59 is stretched to store energy. When the baffle 52 on the right side of the auger 51 abuts against the right side wall in the dust cover 2, the push bench 22 at the right end in the dust cover 2 is inserted into the through hole 35 on the right side of the mounting plate 32, and then the elastic expansion block 57 on the right side of the baffle 52 is pushed out of the through hole 35, so that the elastic expansion block 57 is received in the baffle 52, thereby realizing the unlocking of the right side of the baffle 52 and the mounting plate 32. Then the two springs are released, and then drive the drive rod 54 to rotate quickly. At this time, the baffle 52 on the left side of the auger 51 moves quickly to the upper side of the auger 51, and when the baffle 52 moves to the uppermost side in the sliding groove 33, it will impact the inner wall of the sliding groove 33, thereby causing the mounting plate 32 to drive the moving plate 31 to vibrate, so as to shake off the resin sand adhered to the surface of the moving plate 31 and the baffle 52. At the same time, the baffle 52 on the right side of the auger 51 moves quickly downward and impacts the upper end surface of the mold, so that the mold vibrates, thereby making the resin sand at the rightmost end in the mold cavity more dense and more uniform.

[0055] When the moving frame 3 moves left in the dust cover 2 and gradually approaches the leftmost end in the dust cover 2, the lower end of the gear 55 meshes with the rack 21 at the left end in the dust cover 2, and as the moving frame 3 continues to move left, the gear 55 rotates relative to the driving rod 54, and as the gear 55 rotates relative to the driving rod 54, the protrusion 59 slides in the arc-shaped slot, at this time the spring on the left side of the protrusion 59 is compressed and stored, and the spring on the right side of the protrusion 59 is stretched and stored, when the baffle 52 on the left side of the auger 51 abuts against the left side wall in the dust cover 2, the push bench 22 at the left end in the dust cover 2 is inserted into the through hole 35 on the left side of the mounting plate 32, and then the elastic expansion block 57 on the left side of the baffle 52 is pushed out of the through hole 35, so that the elastic expansion block 57 is received in the baffle 52, thereby achieving the unlocking of the baffle 52 and the mounting plate 32, and then the two springs are released, thereby driving the driving rod 54 to rotate quickly, at this time the baffle 52 on the right side of the auger 51 quickly moves up to above the auger 51, and when the baffle 52 moves to the uppermost position in the sliding groove 33, it will hit the inner wall of the sliding groove 33, thereby causing the mounting plate 32 to drive the moving plate 31 to vibrate, so as to shake off the resin sand adhered to the surface of the moving plate 31 and the baffle 52, at the same time, the baffle 52 on the left side of the auger 51 quickly moves down and hits the upper end face of the mold, causing the mold to vibrate, thereby making the resin sand filled in the leftmost end of the mold cavity more dense and evenly distributed.
