DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all of them. Generally, the components of the embodiments of the present disclosure described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the present disclosure as claimed, but merely represents selected embodiments of the present disclosure. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] In the description of the present disclosure, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present disclosure.

[0039] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0040] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0041] Unless otherwise expressly specified or limited, terms such as "disposed" and "connected" should be interpreted broadly. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present disclosure may be combined with each other.

[0043] As mentioned in the background, a core shooter is a casting machine configured to inject a core sand mixture with a solid or liquid hot resin binder into a heated core box, where it solidifies to form a sand core. Existing core shooters primarily utilize hydraulic systems to lift or lower the core box, shoot sand, and blow air. These machines are primarily used for producing small and medium-sized sand cores. Larger cores place significant pressure on the entire machine frame. Insufficient rigidity or poor stability can cause vibration, deformation, or deviation in the core shot, significantly impacting core quality.

[0044] Furthermore, there are currently no automated core shooters on the market specifically designed for large sand cores. The production of large castings is often done manually, resulting in low production efficiency and a single core-making process, which presents certain production limitations. During the sand shooting and air-blow curing process of large core shooters, a high-load clamping force is required to press the shooting plate and air distribution plate against the core box to ensure proper operation. However, existing synchronous clamping mechanisms have limited load capacity and a limited scope of application, making them unable to meet the operational requirements of ultra-large core shooters.

[0045] In addition, the self-hardening sand process currently used in large-scale casting molding production lines mostly involves artificial sand pressing or vibration compaction, resulting in poor sand core compactness and uniformity, and the strength cannot be guaranteed; the self-hardening sand process is affected by the complexity of the workpiece in the manufacture of large castings, and the cold core and automatic core making processes of the core shooting machine cannot be used. In special circumstances, it cannot meet specific shape and size requirements.

[0046] Therefore, at this stage, the foundry market does not have a core shooting machine for ultra-large sand cores to meet the requirements of greater sand core production capacity and product adaptability, thereby being able to produce castings of larger sizes and more complex shapes to meet the production needs of ultra-large castings.

[0047] Please refer to Figures 1 to 10. The gantry core shooting machine 100 provided in the embodiment of the present disclosure can solve the above problems, which will be described in detail below.

[0048] 1 and 2 , the gantry core shooting machine 100 includes a transmission member 120, a sand shooting member 130, an air blowing member 140, a support member 150 and a gantry 110; wherein the transmission member 120, the sand shooting member 130, the air blowing member 140 and the support member 150 are arranged in sequence from top to bottom, the sand shooting member 130 is connected to the transmission member 120 and the air blowing member 140 at the same time, the support member 150 is configured to accommodate sand cores, the sand shooting member 130 and the air blowing member 140 are both connected to the gantry 110, the gantry 110 is configured to drive the sand shooting member 130, the air blowing member 140 and the transmission member 120 to move, and the transmission member 120 is configured to transmit sand and gas to the sand shooting member 130.

[0049] During operation, the gantry core shooting machine 100 can drive the sand shooting part 130, the blowing part 140 and the transmission part 120 to move through the gantry 110 to facilitate the sand shooting operation of ultra-large sand cores; and the transmission part 120 can transmit sand and gas respectively in different working stages, thereby simplifying the sand supply and gas supply structures, thereby improving the core shooting efficiency.

[0050] It is worth noting that, in order to ensure the stability of sand feeding, the gantry core shooting machine 100 further includes a sand guide hopper 180. The sand guide hopper 180 has a structure that is larger at the top and smaller at the bottom. The sand guide hopper 180 is configured to gather sand materials for supply.

[0051] 3 , the gantry 110 includes a track 111 , rollers 112 and a gantry body 113 . The rollers 112 are mounted at the bottom of the gantry body 113 and roll with the track 111 . The gantry body 113 is connected to the transmission member 120 , the sand-shooting member 130 and the air-blowing member 140 .

[0052] In this embodiment, the track 111 is provided in two rows and is in an I-shape. The gantry 113 has an n-shaped structure. Its two bottom ends respectively roll along the two rows of tracks 111 via n rollers 112, thereby driving the sand shooting unit 130, the air blowing unit 140, and the transmission unit 120 to move. In the case of producing very large sand cores, multiple support members 150 can be arranged along the extension direction of the track 111. After the sand shooting operation of the sand core in one support member 150 is completed, the gantry 110 can move with the rollers 112 and drive the sand shooting unit 130, the air blowing unit 140, and the transmission unit 120 to move to the support member 150 of the next station to continue the sand shooting operation. While the sand shooting and core making operation is in progress, the previous station where the core has been made can also carry out the coring operation, thereby improving the overall core shooting efficiency.

[0053] 4 and 5 , the transmission member 120 includes a transmission chamber 121 and a movable transmission vehicle 122 . The movable transmission vehicle 122 is movably connected between the transmission chamber 121 and the sand-shooting member 130 .

[0054] Optionally, 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. The air inlet 1212 and the exhaust port 1214 are both connected to the air guiding annular cavity 1213. The air guiding annular cavity 1213 is arranged in an annular shape on the outside of the sand adding channel 1211. The mobile transmission vehicle 122 can be selectively connected to the sand adding channel 1211 or the air guiding annular cavity 1213.

[0055] 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 an annular shape on the cylindrical outside of the sand adding channel 1211, the air inlet is configured to connect to the air bag for gas supply, and the exhaust hole is configured to connect to the muffler for gas exhaust.

[0056] Optionally, the mobile transfer vehicle 122 includes a transfer wheel 1221, a transfer frame 1222 and a transfer disc 1223. The transfer wheel 1221 and the transfer disc 1223 are both installed on the transfer frame 1222. The transfer disc 1223 is provided with a sand passing hole 1224 and an air passing hole 1225. The sand passing hole 1224 is configured to be connected to the sand adding channel 1211, and the air passing hole 1225 is configured to be connected to the air guide annular cavity 1213.

[0057] The transmission wheel 1221 cooperates with the gantry body 113 and is configured to drive the transmission frame 1222 and the transmission plate 1223. When conveying abrasive material, the transmission wheel 1221 moves so that the sand passage hole 1224 is connected to the sand feeding channel 1211. At this time, the air passage hole 1225 and the air guide annular cavity 1213 are staggered, facilitating the conveying of abrasive material. When air is required, the transmission wheel 1221 moves so that the air passage hole 1225 is connected to the air guide annular cavity 1213. At this time, the sand passage hole 1224 and the sand feeding channel 1211 are staggered.

[0058] Referring to Figure 6 , the sand-shooting unit 130 includes, from top to bottom, a connecting plate 131, a shooting tube 132, a shooting head 133, and a shooting plate 134. A guide rod 135 is disposed between the connecting plate 131 and the shooting plate 134. A spring 136 is sleeved on the end of the guide rod 135 near the connecting plate 131. A guide sleeve 137 is sleeved on the guide rod 135 and positioned below the spring 136. The connecting plate 131, the shooting tube 132, the shooting head 133, and the shooting plate 134 are all provided with sand-shooting channels, thereby enabling sand-shooting operations.

[0059] 7 and 8 , the support member 150 includes a fixing seat 152 and a lower core box 151. The fixing seat 152 is located below the lower core box 151. The lower core box 151 is configured to accommodate sand cores and communicate with the blower 140. The fixing seat 152 is configured to support the lower core box 151. Furthermore, the support member 150 may also include an upper core box 153 located above the lower core box 151. A lifting mechanism for the upper core box 153, powered by n oil cylinders, is located on both sides of the bottom of the upper core box 153.

[0060] The blowing member 140 includes a blowing wheel 141 , a blowing frame 142 and a blowing plate 143 . The blowing wheel 141 and the blowing plate 143 are both mounted on the blowing frame 142 . The blowing plate 143 is provided with a blowing channel.

[0061] It is worth noting that when the sand shooting piece 130 shoots the core toward the lower core box 151, the blowing wheel 141 drives the blowing frame 142 and the blowing plate 143 to be staggered with the sand shooting piece 130; when the core shooting is completed and the sand core needs to be blown and cured, the blowing wheel 141 drives the blowing frame 142 and the blowing plate 143 to move to the upper side of the upper core box 153, and the blowing channel is configured to transmit gas so that the sand core in the lower core box 151 can be quickly cured.

[0062] In addition, a plurality of exhaust holes are opened on the lower core box 151 , each of which is provided with an exhaust plug. Sand is injected into the lower core box 151 , and gas is discharged from the gap of the exhaust plug, and the sand remains in the lower core box 151 .

[0063] 1 and 9 , the gantry core shooting machine 100 further includes a mold locking member 160 . The mold locking member 160 is connected to the gantry 110 and abuts against the supporting member 150 and the transmission member 120 .

[0064] Optionally, the clamping member 160 includes a clamping power source 161, a clamping guide plate 162, a first clamping rod 163 and a second clamping rod 164. The clamping guide plate 162 and the clamping power source 161 are both connected to the gantry 110, the first clamping rod 163 is supported on the support member 150, and the second clamping rod 164 is supported on the transmission member 120.

[0065] During the operation, the clamping power source 161 provides power, the clamping guide plate 162 plays a supporting role, and the first clamping rod 163 and the second clamping rod 164 rotate to respectively press against the fixed seat 152 in the support 150 and the transmission chamber 121 in the transmission member 120 to ensure the stable progress of the sand shooting operation.

[0066] Furthermore, the side-mounted clamping element 160 reduces the overall height of the gantry core shooter 100 and facilitates maintenance. Furthermore, when in the clamped state, the connecting rods driving the first clamping rod 163 and the second clamping rod 164 are angled at approximately 180°, achieving maximum clamping force with minimal power consumption.

[0067] Referring to Figure 10 , the gantry core shooter 100 also includes a height compensation member 170, which comprises a compensation power source 171, compensation connecting rods 172, and compensation pads 173. The ends of the three compensation connecting rods 172 closest to the compensation power source 171 are connected to the compensation power source 171, and the three compensation pads 173 are connected to each other via the compensation connecting rods 172. During the mold clamping process, the second clamping rod 164 abuts against the compensation pads 173, which are higher than the height 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 height compensation.

[0068] The embodiment of the present disclosure further provides a core shooting method of the gantry core shooting machine 100, which includes:

[0069] 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 piece 130 and the lower core box 151 can be spaced apart during the pre-filling process.

[0070] S2: Control the locking mold part 160 to lock the transmission part 120, the sand shooting part 130, the lower core box 151 and the fixed seat 152 to start the sand shooting operation; before the sand shooting operation, it is necessary to control the mobile transmission vehicle 122 to move to separately supply sand and gas to the sand shooting part 130, and before locking, make the compensation pad 173 of the height compensation part 170 abut against the locking mold part 160; and after the sand shooting operation, exhaust treatment is required through the exhaust port 1214.

[0071] S3: Control the mold locking component 160 to unlock, and move the air blowing component 140 to the lower side of the sand shooting component 130; after unlocking, the compensation pad 173 of the height compensation component 170 is separated from the mold locking component 160.

[0072] S4: Control the mold locking 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 blowing component 140 to perform the blowing and curing operation;

[0073] S5: After curing is completed, the locking mold 160 is controlled to open.

[0074] S6: Control the blowing member 140 to move away.

[0075] S7: The upper core box 153 is controlled to be lifted and separated from the lower core box 151.

[0076] S8: The gantry 110 drives the transmission component 120, the sand-shooting component 130, and the air-blowing component 140 to leave the lower core box 151;

[0077] S9: Use a sling to lift the prepared sand core out of the lower core box 151.

[0078] The above operation process is a sandblasting operation at one workstation. When one workstation is completed, the gantry 110 can drive the main components to move to the next workstation to continue the sandblasting operation and repeat the above steps.

[0079] In summary, the gantry core shooting machine 100 and the core shooting method thereof provided by the embodiments of the present disclosure have at least the following advantages:

[0080] (1) The lower core box 151 can be fixed on the fixed seat 152, and the sand shooting parts 130 can be driven to move by moving the gantry 110, thereby achieving low energy consumption operation;

[0081] (2) By setting up the sand guide hopper 180, the lower core box 151 of multiple stations can be pre-filled with sand, which can be carried out simultaneously with the sand shooting operation, thereby improving the overall operation efficiency;

[0082] (3) The movement of the gantry 110 drives the sand-shooting part 130, the air-blowing part 140 and the transmission part 120 to move, thereby realizing the multi-station use of a set of equipment and improving the working efficiency.

[0083] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto.
