Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] Unless otherwise explicitly specified and limited, terms such as "setup" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0040] As described in the background section, a core shooter is a casting device used to inject a core sand mixture, with solid or liquid thermoplastic resin as a binder, into a heated core box, where it solidifies to form a sand core. Existing core shooters mainly utilize hydraulic systems to lift or press down the core box, shoot sand, and blow air, and are primarily used for producing small to medium-sized sand cores. When the sand core is large, the overall frame of the equipment will bear significant pressure. Insufficient rigidity or poor stability may cause equipment vibration, deformation, or core shooting deviation, greatly affecting the core quality.

[0041] Furthermore, there are currently no automated core shooters on the market specifically designed for large sand cores, and the production of large castings is mostly done manually, resulting in low production efficiency, a limited core-making process, and certain production limitations. During the sand shooting and air-blowing curing processes of large core shooters, a high-load clamping force is required to press the shooting plate and air distribution plate firmly onto the core box to ensure the normal operation of sand shooting and air-blowing curing. However, existing synchronous clamping mechanisms have limited load capacity and a narrow range of applications, failing to meet the operational requirements of ultra-large core shooters.

[0042] Furthermore, the self-hardening sand process currently used in large casting molding production lines mostly involves manual sand pressing or vibration compaction, resulting in poor core compaction and uniformity, and the strength cannot be guaranteed. The service life and cycle of self-hardening sand are short, and once it solidifies, it cannot be reused, resulting in relatively high usage costs. The self-hardening sand process is affected by the complexity of the workpiece in the manufacture of large castings, and it cannot use the cold core and mechanical core processes of core shooters, thus failing to meet specific shape and size requirements in special circumstances.

[0043] Therefore, at present, there is no core shooter in the casting market specifically designed for ultra-large sand cores to meet the needs of greater sand core production capacity and product adaptability, thereby enabling the production of castings with larger dimensions and more complex shapes to meet the production requirements of ultra-large-scale castings.

[0044] Please refer to Figures 1-10 The gantry core shooting machine 100 provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0045] refer to Figure 1 and Figure 2 The gantry core shooting machine 100 includes a transmission component 120, a sand shooting component 130, an air blowing component 140, a support component 150, and a gantry frame 110. The transmission component 120, the sand shooting component 130, the air blowing component 140, and the support component 150 are arranged sequentially from top to bottom. The sand shooting component 130 is connected to both the transmission component 120 and the air blowing component 140. The support component 150 is used to hold the sand core. The sand shooting component 130 and the air blowing component 140 are both connected to the gantry frame 110. The gantry frame 110 is used to drive the sand shooting component 130, the air blowing component 140, and the transmission component 120 to move. The transmission component 120 is used to transmit sand and gas to the sand shooting component 130.

[0046] During operation, the gantry core shooter 100 can move the sand shooting component 130, the air blowing component 140 and the transmission component 120 through the gantry frame 110 to facilitate sand shooting operations for ultra-large sand cores; and the transmission component 120 can transmit sand and gas separately in different working stages, which simplifies the sand and gas supply structure and improves core shooting efficiency.

[0047] It is worth noting that, in order to ensure the stability of sand feeding, the gantry core shooter 100 also includes a sand guide bucket 180, which has a structure that is larger at the top and smaller at the bottom. The sand guide bucket 180 is used to collect sand for supply.

[0048] refer to Figure 3 The gantry frame 110 includes a track 111, rollers 112 and a gantry frame body 113. The rollers 112 are installed at the bottom of the gantry frame body 113 and roll in cooperation with the track 111. The gantry frame body 113 is also connected to the transmission component 120, the sand-shooting component 130 and the air-blowing component 140.

[0049] In this embodiment, the tracks 111 are arranged in two columns in an I-shape, and the gantry frame 113 has an n-shaped structure. Its two bottom ends are connected by n rollers 112 that roll along the two columns of tracks 111, thereby driving the sand-shooting component 130, the air-blowing component 140, and the conveying component 120 to move. In the case of producing ultra-large sand cores, multiple support components 150 can be arranged along the extension direction of the tracks 111. After the sand-shooting operation of the sand core in one support component 150 is completed, the gantry frame 110 can move with the rollers 112, and drive the sand-shooting component 130, the air-blowing component 140, and the conveying component 120 to the support component 150 of the next station to continue the sand-shooting operation. While the sand-shooting core-making operation is being carried out, the core-removal operation can be carried out at the previous station where the core has been made, thereby improving the overall core-shooting efficiency.

[0050] refer to Figure 4 and Figure 5 The transmission component 120 includes a transmission chamber 121 and a mobile transmission vehicle 122, which is movably connected between the transmission chamber 121 and the sand-shooting component 130.

[0051] Specifically, the transmission chamber 121 is provided with a sand-adding channel 1211, an air inlet 1212, an air-guiding annular cavity 1213, and an exhaust port 1214. Both the air inlet 1212 and the exhaust port 1214 are connected to the air-guiding annular cavity 1213. The air-guiding annular cavity 1213 is arranged in a ring outside the sand-adding channel 1211. The mobile transmission vehicle 122 can be selectively connected to either the sand-adding channel 1211 or the air-guiding annular cavity 1213.

[0052] In this embodiment, the sand adding channel 1211 is cylindrical, and sand can be added through the sand adding channel 1211; the air guiding annular cavity 1213 is arranged in a ring outside the cylinder of the sand adding channel 1211, the air inlet is used to connect to the air bag for gas supply, and the exhaust port is used to connect to the silencer for gas discharge.

[0053] Specifically, the mobile transfer vehicle 122 includes transfer wheels 1221, a transfer frame 1222, and a transfer disc 1223. Both the transfer wheels 1221 and the transfer disc 1223 are mounted on the transfer frame 1222. The transfer disc 1223 has a sand passage hole 1224 and an air passage hole 1225. The sand passage hole 1224 is used to communicate with the sand filling channel 1211, and the air passage hole 1225 is used to communicate with the air guiding annular cavity 1213.

[0054] The transfer wheel 1221 cooperates with the gantry frame 113 and is used to drive the transfer frame 1222 and the transfer disc 1223 to move. When transferring sand, the movement of the transfer wheel 1221 connects the sand passage hole 1224 with the sand filling channel 1211. At this time, the air passage hole 1225 and the air guiding annular cavity 1213 are staggered to facilitate the transfer of sand. When it is necessary to conduct gas, the movement of the transfer wheel 1221 connects the air passage hole 1225 with the air guiding annular cavity 1213. At this time, the sand passage hole 1224 and the sand filling channel 1211 are staggered.

[0055] refer to Figure 6 The sand-shooting component 130 includes a connecting plate 131, a shooting cylinder 132, a shooting head 133, and a shooting plate 134 arranged sequentially from top to bottom. A guide rod 135 is also provided between the connecting plate 131 and the shooting plate 134. A spring 136 is sleeved on one end of the guide rod 135 near the connecting plate 131, and a guide sleeve 137 is also sleeved on the guide rod 135, located below the spring 136. The connecting plate 131, the shooting cylinder 132, the shooting head 133, and the shooting plate 134 are all provided with sand-shooting channels, thereby realizing sand-shooting operations.

[0056] refer to Figure 7 and Figure 8 The support member 150 includes a fixed base 152 and a lower core box 151. The fixed base 152 is located below the lower core box 151. The lower core box 151 is used to accommodate the sand core and communicates with the air blowing component 140. The fixed base 152 is used to support the lower core box 151. In addition, the support member 150 may also include an upper core box 153, which is located above the lower core box 151. The bottom sides of the upper core box 153 are equipped with lifting mechanisms for the upper core box 153, which are powered by n hydraulic cylinders.

[0057] The air blowing component 140 includes an air blowing component wheel 141, an air blowing component frame 142, and an air blowing cover 143. The air blowing component wheel 141 and the air blowing cover 143 are both mounted on the air blowing component frame 142, and the air blowing cover 143 has an air blowing channel.

[0058] It is worth noting that when the sand-shooting component 130 is shooting the core towards the lower core box 151, the air-blowing component wheel 141 drives the air-blowing component frame 142 and the air-blowing hood 143 to be offset from the sand-shooting component 130; when the core shooting is completed and the sand core needs to be cured by air blowing, the air-blowing component wheel 141 drives the air-blowing component frame 142 and the air-blowing hood 143 to move to the upper side of the upper core box 153, and the air blowing channel is used to transmit gas so that the sand core in the lower core box 151 can be cured quickly.

[0059] Furthermore, the lower core box 151 is provided with multiple vent holes, each equipped with a vent plug. When sand is injected into the lower core box 151, the gas is discharged from the gap of the vent plug, and the sand remains inside the lower core box 151.

[0060] refer to Figure 1 and Figure 9 The gantry core shooting machine 100 also includes a locking mold component 160, which is connected to the gantry frame 110 and abuts against the support component 150 and the transmission component 120.

[0061] Specifically, the mold locking component 160 includes a mold locking power source 161, a mold locking guide plate 162, a first mold locking rod 163, and a second mold locking rod 164. The mold locking guide plate 162 and the mold locking power source 161 are both connected to the gantry frame 110. The first mold locking rod 163 abuts against the support member 150, and the second mold locking rod 164 abuts against the transmission member 120.

[0062] During operation, the mold-locking power source 161 provides power, the mold-locking guide plate 162 provides support, and the first mold-locking rod 163 and the second mold-locking rod 164 rotate to press against the fixed seat 152 in the support member 150 and the transmission chamber 121 in the transmission member 120 respectively, so as to ensure the stable operation of sand shooting.

[0063] Furthermore, the mold-locking component 160 is located on the side, which reduces the overall height of the gantry core shooting machine 100 and facilitates maintenance. Simultaneously, in the mold-locking state, the angle between the two connecting rods driving the first mold-locking rod 163 and the second mold-locking rod 164 is close to 180°, achieving a low-power effect of using minimal power to achieve maximum mold-locking force.

[0064] refer to Figure 10The gantry core shooting machine 100 also includes a height compensation component 170, which comprises a compensation power source 171, compensation connecting rods 172, and compensation pads 173. One end of the three compensation connecting rods 172 closest to the compensation power source 171 is connected to the compensation power source 171. The three compensation pads 173 are connected to each other via the compensation connecting rods 172. During mold clamping, the second mold clamping rod 164 presses against the compensation pads 173, whose height is higher than that of the compensation power source 171. When height compensation is required, the compensation power source 171 drives the compensation connecting rods 172 to extend or retract, causing the compensation pads 173 to move synchronously, thereby achieving the height compensation operation.

[0065] Embodiments of the present invention also provide a core shooting method for a gantry core shooter 100, comprising:

[0066] S1: 70% of the sand is pre-filled into the lower core box 151 through the sand guide hopper 180; in order to avoid interference, the sand shooting part 130 and the lower core box 151 can be spaced apart during the pre-filling process.

[0067] S2: Control the locking mold component 160 to lock the transmission component 120, the sand-shooting component 130, the lower core box 151, and the fixed seat 152 to start the sand-shooting operation; before the sand-shooting operation, the mobile transmission vehicle 122 needs to be moved to supply sand and gas to the sand-shooting component 130 separately, and before locking, the compensation pad 173 of the height compensation component 170 should abut against the locking mold component 160; and after the sand-shooting operation, exhaust should be performed through the exhaust port 1214.

[0068] S3: Control the locking mold 160 to unlock and move the air blowing part 140 to the lower side of the sand shooting part 130; after unlocking, the compensation pad 173 of the height compensation part 170 is disengaged from the locking mold 160.

[0069] S4: Control the locking mold component 160 to lock the transmission component 120, the sand shooting component 130, the lower core box 151 and the fixing seat 152 again, and control the air blowing component 140 to perform air blowing curing operation.

[0070] S5: After curing is complete, control the locking mold 160 to open.

[0071] S6: Control the air blowing component 140 to move away.

[0072] S7: Control the upper core box 153 to be lifted and detached from the lower core box 151.

[0073] S8: The gantry frame 110 drives the transmission component 120, the sand-shooting component 130, and the air-blowing component 140 to leave the lower core box 151;

[0074] S9: Use a lifting device to lift out the prepared sand core from the lower core box 151.

[0075] The above operation process is a sand-shooting operation at one station. When one station is completed, the gantry 110 can move the main components to the next station to continue the sand-shooting operation, and repeat the above steps.

[0076] In summary, the gantry core shooter 100 and its core shooting method provided by the embodiments of the present invention have at least the following advantages:

[0077] (1) The lower core box 151 can be fixed on the fixed base 152, and the sand shooting parts 130 can be moved by the moving gantry frame 110, thereby achieving low-energy operation;

[0078] (2) By setting up the sand guide bucket 180, the pre-filling sand operation of the lower core box 151 of multiple workstations can be realized, which is carried out simultaneously with the sand shooting operation, thereby improving the overall operation efficiency.

[0079] (3) The movement of the gantry frame 110 drives the sand-shooting component 130, the air-blowing component 140 and the transmission component 120 to move, realizing the use of multiple workstations of a set of equipment and improving the work efficiency.

[0080] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
