Description

Technical Field

[0001] The invention belongs to the field of coated sand hydraulic production equipment, and in particular relates to a full-automatic vertical core shooting machine with front and rear running car functions. Background Art

[0002] Coated sand casting is a type of sand casting. Using coated sand to produce coated sand castings is a casting method with low energy consumption, especially the recycling of waste sand. Core shooting machines can be used to produce coated sand hydraulics. The injection molding machine uses compressed air to evenly inject the molding sand into the sand box for pre-compaction, and then applies pressure for compaction. Commonly used ones are vertical parting boxless injection molding machines and horizontal parting boxless injection molding machines. The vertical parting boxless injection molding machine does not use a sand box for molding. The molding sand is directly injected into the molding chamber with a template. The sand mold has high dimensional accuracy, there are cavities on both sides of the sand box, and the productivity is high, but it is difficult to core, and the quality requirements of the molding sand are strict. The horizontal parting boxless injection molding machine uses a sand box for molding. After the sand mold is made, the mold is closed and the box is removed. It is convenient to core and has high productivity.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] Examples, such as Figures 1 to 13 As shown, the present invention provides a fully automatic vertical core shooting machine with a forward and backward running function, including a vertical core shooting machine 1, the vertical core shooting machine 1 including two vertical core shooting stations 2, each of which is provided with a mold opening and closing device 3 below the vertical core shooting station 2, the mold opening and closing device 3 has a horizontal mold opening and closing function, the mold opening and closing device 3 is provided with a flipping operating mechanism 4 for flipping the mold, a lifter 5 is provided in the flipping direction of the flipping operating mechanism 4, a push mechanism 6 for pushing the coated sand product is provided on one side of the lifter 5, and a conveyor 7 for transferring the coated sand product by forward and backward running is provided on the side of the lifter 5 opposite to the push mechanism 6. Among them, each vertical core shooting station 2 corresponds to a set of mold opening and closing devices 3, flipping operating mechanisms 4, lifters 5, push mechanisms 6 and conveyors 7. Specifically, the elevator 5 can be raised to the bottom of the opening and closing mold device 3 in a high position in a lifting manner, and the flipping operating mechanism 4 drives the opening and closing mold device 3 to flip by flipping, and the coated sand product on the opening and closing mold device 3 falls on the elevator 5; the elevator 5 falls in a lifting manner and connects to the conveyor 7 in a low position, and the pushing mechanism 6 can push the coated sand product on the elevator 5 to the conveyor 7, and the conveyor 7 carries the coated sand product in the workshop for running operation, and transfers the coated sand product from the vertical core shooting machine 1 in a back-and-forth running manner, so as to realize the mobile transfer of the coated sand product, and the periodic operation performance is good, thereby effectively improving the production efficiency.

[0035] Furthermore, in order to improve the workshop environment around the equipment, the present invention is provided with a protective box 8 outside the vertical core shooting machine 1, and a door frame opposite to the vertical core shooting station 2 is provided on the front side of the protective box 8, and a double-opening box door 81 that slides with the door frame is provided on the protective box 8, and two symmetrically distributed running ports 82 are provided below the door frame of the protective box 8, and the running ports 82 are used to cooperate with the conveyor 7 to provide a reasonable space basis for the conveyor 7 to run and transport the coated sand products back and forth. The protective box 8 can protect the environment near the vertical core shooting station 2 to prevent a large amount of dust from being attached to other equipment during the sand shooting operation. Further, the rear side of the protective box 8 provided by the present invention is more convex than the front side, so as to facilitate the air to flow backwards; two convection fans 9 distributed on the left and right sides of the protective box 8 are provided inside the protective box 8, and a filter outlet 83 is provided on the rear side of the protective box 8, and a guide heat dissipation component 10 is provided inside the protective box 8 and located at the interval between the two elevators 5. Among them, the convection fan 9 is used to promote the flow of air inside the protection box 8, especially the air around the vertical core shooting station 2. The heat generated by the core shooting operation in the air within this range can be dissipated through the guide heat dissipation component 10, and heat exchange is completed with the air outside the protection box 8, which is beneficial to reduce the temperature of the coated sand mold (remove the "mold") product, and to a certain extent, it can improve the actual service life of the elevator 5 and the conveyor 7. When the air after the guide heat exchange is discharged from the protection box 8 through the filter outlet 83, a certain particle size of filtration can be achieved, which can prevent the air from carrying core shooting sand particles into the workshop.

[0036] In order to improve the connection performance of the mold opening and closing device 3, the flip operating mechanism 4 and the elevator 5, the mold opening and closing device 3 provided by the present invention includes a first positioning plate 31, a second positioning plate 32 and a third positioning plate 33, the first positioning plate 31, the second positioning plate 32 and the third positioning plate 33 are connected by a positioning rod 34 located at the corner position of the three, and a mold opening and closing hydraulic cylinder 35 is arranged on the side of the third positioning plate 33 facing away from the second positioning plate 32, and the telescopic end of the mold opening and closing hydraulic cylinder 35 passes through the third positioning plate 33 and is connected to the second positioning plate 32. Plate 32, four connecting sleeves 36 are arranged on the side of the second positioning plate 32 facing the first positioning plate 31, and a pair of sliding sleeves 37 are arranged at the ends of the four connecting sleeves 36, and every two connecting sleeves 36 correspond to one sliding sleeve 37, and the connecting sleeves 36 and the sliding sleeves 37 are both slidably matched with the positioning rod 34, and a mounting plate 38 for mounting the template is hingedly arranged between the sliding sleeves 37, and the connecting sleeves 36 can control the distance between the second positioning plate 32 and the mounting plate 38; the side of the mounting plate 38 facing away from the template is connected to the flip operating mechanism 4. Among them, the mold opening and closing hydraulic cylinder 35 can drive the second positioning plate 32, the flip operating mechanism 4, the mounting plate 38 and the mold cavity to move toward the vertical core shooting station 2. After the vertical core shooting station 2 completes the core shooting, the mold opening and closing hydraulic cylinder 35 moves in the opposite direction to complete the mold separation. The coated sand mold product after the mold separation is still in the mold cavity on the mounting plate 38, and the elevator 5 is raised to the bottom of the mold cavity by lifting; the flip operating mechanism 4 drives the mounting plate 38 to flip around the hinge center between it and the sliding sleeve 37, thereby pouring the coated sand product onto the elevator 5. Therefore, the mold opening and closing device 3, the flip operating mechanism 4 and the elevator 5 provided by the present invention can effectively complete the action connection, and also avoid the vertical core shooting station 2, which can effectively ensure the working efficiency of the device.

[0037] In order to improve the mold turning performance of the flip operating mechanism 4, the flip operating mechanism 4 provided by the present invention includes two first hinges 41 arranged on the mounting plate 38, the first hinges 41 cooperate with the hinge shaft 44 arranged on the side of the sliding sleeve 37, and the second hinges 42 and the third hinges 43 are arranged on the opposite surfaces of the mounting plate 38 and the second positioning plate 32, respectively, and the flip driving cylinder 45 is arranged on the second hinge 42 and the third hinge 43, and the telescopic end of the flip driving cylinder 45 is connected to the second hinge 42 with a rotation axis, and the cylinder barrel of the flip driving cylinder 45 is provided with a shaft head 46 connected to the third hinge 43 with a rotation axis, and the shaft head 46 is arranged at a position close to the telescopic sealing end of the flip driving cylinder 45. Since the second hinge 42 and the third hinge 43 are staggered in distribution, the flip driving cylinder 45 is installed between the second positioning plate 32 and the mounting plate 38 in an inclined assembly manner, which is conducive to improving the overall utilization rate of space. Specifically, the flipping drive cylinder 45 drives the mounting plate 38 to flip around the matching center of the first hinge 41 and the hinge shaft 44 by telescoping; since the spatial position of the second hinge 42 connected to the flipping drive cylinder 45 changes, the flipping drive cylinder 45 will adaptively rotate around the shaft head 46 and the matching center of the third hinge 43, thereby ensuring the completion of the entire mold flipping action and avoiding the occurrence of dead points in the action, which is beneficial to improving the efficiency of the flipping operating mechanism 4 in flipping the mold onto the elevator 5.

[0038] In order to improve the safety of the coated sand mold falling on the elevator 5, the elevator 5 provided by the present invention is a scissor-type elevator, and anti-stripping roller rows 11 are arranged on both sides of the top surface of the scissor-type elevator. The anti-stripping roller row 11 includes a side seat 111, and the side seat 111 is provided with a plurality of mounting shafts 112 distributed along its length direction, and the mounting shaft 112 is provided with a roller 113. Among them, the scissor-type elevator has folding function and lifting function, and has good supporting effect and lifting stability, which can ensure that the coated sand shell core product rises and falls smoothly with it. The anti-stripping roller row 11 can increase the actual longitudinal span of the elevator 5, and the inclined roller 113 can make the fallen coated sand shell core move toward the center position of the elevator 5, avoiding the instantaneous large-scale lift of the center of the elevator 5 when the coated sand mold product falls, which not only ensures the efficiency of the elevator 5 in receiving the coated sand shell core, but also facilitates the subsequent pushing mechanism 6 to accurately and evenly push the coated sand shell core to the conveying surface of the conveyor 7.

[0039] Furthermore, the center of the roller 113 provided by the present invention is provided with a spring mounting hole 114, a spring 115 is provided in the spring mounting hole 114, the mounting shaft 112 is provided at the center of the spring 115 and an end nut 116 is provided at its end for limiting the spring 115. In this way, the roller 113 has a certain amount of play in the axial direction of the mounting shaft 112, so that after being subjected to the pressure of the coated sand product, it can be quickly buffered and reset, which not only ensures its protective effect on the coated sand product, but also helps to ensure the landing accuracy of the coated sand product on the elevator 5.

[0040] Since the coated sand product will carry a part of the molding sand when it falls from the mold opening and closing device 3 to the elevator 5, in order to avoid the molding sand accumulating on the surface of the elevator 5 to form a slope and affect the landing effect of the coated sand product, the present invention adopts a design for timely recovery of the molding sand. Specifically, the present invention is provided with a sand recovery device 12 at the bottom of the elevator 5, and the sand recovery device 12 includes a support box 121, the top surface of the support box 121 supports the elevator 5, and the support box 121 is provided with a U-shaped mouth 122, and the two sides of the U-shaped mouth 122 are distributed at the lower side of the support box 121, and a pair of support components 123 for supporting the contact surface between the support box 121 and the elevator 5 are provided inside the support box 121, and a negative pressure pipe 124 is provided on the side of the support box 121, and a negative pressure pump 125 and a recovery box 126 are provided at one end of the negative pressure pipe 124. Among them, the support box 121 not only has the function of providing a bottom foundation for the elevator 5, but also has the function of temporarily recovering the molding sand. For example, the molding sand that falls on the elevator 5 can gradually fall from the U-shaped mouth 122 from both sides of the elevator 5 into the support box 121 during the process of the pushing mechanism 6 pushing the coated sand product to the conveyor 7. When the molding sand in the support box 121 accumulates to a certain amount, the negative pressure pump 125 provides negative pressure to the negative pressure pipe 124 to pump the molding sand into the recovery box 126, thereby achieving the purpose of recovering the excess molding sand on the elevator 5.

[0041] In order to improve the support strength of the support box 121 to the elevator 5, the present invention sets a support assembly 123 inside the support box 121, and the support assembly 123 specifically includes a support base 1231 set on the bottom surface of the support box 121 and a threaded tube 1232 set on the top surface of the support box 121, and a threaded groove is set on the support base 1231, and a threaded rod 1233 is set between the threaded groove and the threaded tube 1232. In this way, by adjusting the screwing depth of the threaded rod 1233, the threaded groove, and the threaded tube 1232, the purpose of fine-tuning the level of the top surface of the support box 121 can be achieved, especially the position of the support elevator 5, so as to ensure the balance of the elevator 5 and improve the transfer efficiency of the coated sand product of the device.

[0042] In order to improve the utilization rate of the pushing mechanism 6, the pushing mechanism 6 provided by the present invention includes a fixed plate 61, a pushing cylinder 62 is arranged at the rear side of the fixed plate 61, a pushing plate 63 connected to the telescopic end of the pushing cylinder 62 is arranged at the front side of the fixed plate 61, and a pair of limit rods 64 cooperating with the ends of the elevator 5 are arranged below the push plate 63 on the fixed plate 61. Among them, the pushing cylinder 62 can push the coated sand product on the elevator 5 in translation by driving the push plate 63 to move forward and backward, so that the coated sand product can be evenly and stably moved to the conveying surface of the conveyor 7. The limit rod 64 is used to control the front and rear gap between it and the elevator, and a limit switch can be set at the end of the limit rod 64 to improve the accuracy of the lifting position of the elevator.

[0043] The vertical core shooting machine 1 provided by the present invention is provided with a front column 13 and a rear column at the interval between the two elevators 5. The front column 13 and the rear column are originally used as structural supports inside the vertical core shooting machine 1. In order to facilitate the installation of the diversion and heat dissipation component 10, the diversion and heat dissipation component 10 provided by the present invention includes guide plates 101 spaced apart in upper and lower directions. Sockets 102 cooperating with the front column and the rear column are provided at both ends of the guide plates 101, and U-shaped spacers 103 cooperating with the front column and the rear column are provided between adjacent guide plates 101. The bottom of the diversion and heat dissipation component 10 is suspended in the air. At the same time, the top and bottom of the diversion and heat dissipation component 10 cooperate with the crossbeam support arranged inside the vertical core shooting machine 1. Among them, the guide plate 101 is made of a metal material with a high thermal conductivity coefficient and adopts a thin sheet design, which is conducive to the arrangement of a larger density of guide plates 101, and the U-shaped spacer 103 can form a guide channel between adjacent guide plates 101; in this way, the guide and heat dissipation component 10 can be effectively and stably installed inside the vertical core shooting machine 1 in a suspended manner without welding other structures, and contact with the steel structure around the vertical core shooting station 2 to achieve solid-solid heat exchange, and then the heat is carried by the flowing air through the gas to complete the heat exchange with the outside air, thereby ensuring that the internal ambient temperature of the vertical core shooting machine 1 is maintained at around normal temperature.

[0044] In order to improve the utilization rate of the double-opening door 81, the present invention provides transparent windows 84 distributed in a rectangular array on the double-opening door 81. The transparent windows 84 allow the staff to see the actual working conditions of the vertical core shooting station 2 in real time.
