Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a mold release device after the outer mold has hardened. Background Technology

[0002] In industrial production, molds are widely used in metal casting, plastic molding, die casting and other fields. Through precise shape and size control, they enable the mass production of complex parts. Their structural design and production application have a key impact on product quality and production efficiency.

[0003] The outer mold is usually produced by sand casting. The appropriate material is selected according to the structural dimensions of the outer mold and then hardened. After hardening, the formed outer mold needs to be separated from the sand mold. The traditional method of mold removal usually uses a combination of screw and nut. The nut is reinforced on the mold or movable block, and then the mold or movable block is lifted out of the sand mold by turning the screw. This method is cumbersome and time-consuming, which reduces production efficiency. In the process of removing molds for some large castings, hoisting equipment is usually used to assist in the mold removal. However, due to the imbalance of forces during the hoisting process, the mold can easily shake, affecting the quality of the casting and failing to meet the production requirements of high-precision and high-quality outer molds.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figures 1 to 7 The mold release device shown is located at the mold release station 02 on the outer mold conveying path, between the hardening station 01 and the transfer station 03, and includes: a pressing mechanism 10 and a mold flipping mechanism 20.

[0032] The mold flipping mechanism 20 includes a flipping disk 21, the axis of which is set along the outer mold conveying path, and the inner cavity is hollow. A first conveying component 22 and a second conveying component 23 are respectively set at the bottom and top of the vertical plane in the inner cavity. The first conveying component 22 and the second conveying component 23 are respectively used to receive the sand box from the hardening station 01 and the cover plate that limits the top of the sand box.

[0033] The pressing mechanism 10 includes a lifting frame 11 and a limiting card 12. The limiting card 12 is movably disposed at both ends of the lifting frame 11 along the outer mold conveying path to limit the edge of the cover plate or sand box. The lifting frame 11 is fixedly disposed in the tilting plate 21, and its two ends are fixedly connected to the first conveying component 22 and the second conveying component 23 respectively, and drive the first conveying component 22 and / or the second conveying component 23 to move in the vertical direction.

[0034] This invention, by setting up a pressing mechanism 10 and a mold flipping mechanism 20, automatically separates the outer mold from the sand box through the rotation of the flipping plate 21 and the movement of the hoisting bracket, thereby greatly reducing the time of manual operation and improving the speed and efficiency of mold removal. During the mold removal process, the limiting action of the limit card 12 on the sand box or cover plate, combined with the supporting movement of the first conveying component 22 and the second conveying component 23, ensures the uniformity and stability of the force during the mold removal process, and can achieve more stable and accurate separation of the sand box from the outer mold, ensuring the quality of mold removal after the outer mold has hardened.

[0035] Specifically, the tilting disc 21, as the core component of the entire mold-lifting device, is axially positioned along the outer mold conveying path, ensuring that the sand box and mold can accurately change positions during the tilting process, thus separating the sand box from the mold. The hollow inner cavity design provides installation space for the first conveying assembly 22 and the second conveying assembly 23, while also facilitating the arrangement of internal wiring and transmission mechanisms. The first conveying assembly 22 and the second conveying assembly 23 not only support and transport the sand box and cover plate, but also achieve vertical movement through connection with the lifting frame 11, working in conjunction with the tilting disc 21 to complete the mold-lifting operation. The lifting frame 11 provides sufficient support and stability for driving the first conveying assembly 22 and the second conveying assembly 23 to move vertically, ensuring that the sand box and cover plate can move and be positioned smoothly during the mold-lifting process. The limit card 12 ensures that the sand box or cover plate is accurately positioned during conveying and tilting, preventing it from shifting or shaking during movement, thereby ensuring the smooth progress of the mold-lifting process and the accuracy of the mold-lifting position.

[0036] When using the above-mentioned mold-removing device for mold removal, the following steps are generally included:

[0037] The mold-lifting device is located at the mold-lifting station 02 on the outer mold conveying path and is in the initial position. The cover plate is set on the second conveying component 23 by the limit card 12, waiting for the sand box conveyed from the hardening station 01.

[0038] Hardening station 01 transports the sand box to demolding station 02. The first conveying component 22 receives the sand box from hardening station 01, while the limiting card 12 limits the edge of the sand box to ensure that the position of the sand box is accurate and stable.

[0039] The hoisting frame 11 drives the first conveying component 22 and the sand box to move upward in the vertical direction until the top surface of the sand box contacts the cover plate, so that the sand box and the cover plate are tightly connected.

[0040] The tilting disc 21 drives the first conveying component 22, the second conveying component 23, the sand box and the cover plate to rotate 180°, causing the sand box to flip and be in an inverted state. At this time, the sand box is located on top after the flip, while the cover plate is located on the bottom.

[0041] The hoisting frame 11 once again drives the first conveying component 22 and the sand box to move upward in the vertical direction. Since the cover plate is limited by the second conveying component 23, the sand box gradually separates from the mold during the movement, completing the mold removal operation.

[0042] The second conveying assembly 23 will transport the remaining molds and cover plates to the transfer station 03 for subsequent processing or handling;

[0043] Hardening station 01 transports the cover plate to demolding station 02, where the cover plate is limited by limit card 12 to ensure accurate position of the cover plate;

[0044] The flip plate 21 drives the whole to rotate 180° in the opposite direction and return to the initial position. At this time, the first conveying component 22 is set opposite to the transfer station 03. The first conveying component 22 conveys the separated sand box to the transfer station 03, realizing the complete separation of the sand box and the mold, completing the entire mold release process, and preparing for the next round of mold release operation.

[0045] Based on the above embodiments, the flipping disc 21 includes two end discs 211 and auxiliary support arms 212. The two end discs 211 are respectively disposed at both ends of the mold removal station, and the two auxiliary support arms 212 are arranged in parallel between the two end discs 211, with each end fixedly connected to the end disc 211. The two end discs 211 serve as the supporting foundation for the entire flipping disc 21 and must have sufficient strength and stability to withstand the weight and force of components such as the sand box and mold during the mold removal process. The two parallel auxiliary support arms 212 not only enhance the overall structural strength of the flipping disc 21, but also play an auxiliary support and stabilizing role during the flipping process, ensuring the smoothness and accuracy of the flipping action, reducing the risk of sand mold damage caused by possible shaking or imbalance during the flipping process, thereby improving the mold removal quality.

[0046] Based on the above embodiments, the end plate 211 is hollow in the middle to allow the sand box or cover plate to move in or out of the mold-removing station 02. The end plate 211 has a circular structure, and the hollow part in the middle forms a through channel that can accommodate the sand box or cover plate to enter and exit, so as to ensure that it can be stably installed in the mold-removing station 02 and received and limited by the first conveying component 22 or the second conveying component 23. Similarly, after the mold-removing process is completed, it can also be moved out of the mold-removing station 02 through this hollow channel and transported to the subsequent processing or handling process to ensure the smoothness of the conveying process.

[0047] Based on the above embodiments, the flipping mechanism 20 further includes a base 24, a first driving member 25, and a first transmission member 26. The base 24 is fixedly mounted on the ground along the axial direction of the flipping disk 21, and has a receiving groove on its top that mates with the two end disks 211. The first transmission member 26 is distributed between the base 24 and the end disks 211. The first driving member 25 is fixedly mounted on one side of the base 24, and its output end is connected to the first transmission member 26. The base 24 is stably mounted on the ground, providing a stable support foundation for the entire flipping disk 21, while the receiving groove... The working arrangement with the end plate 211 effectively limits the position of the end plate 211 during the flipping process, reduces shaking and offset, and ensures the smoothness of the flipping action. The first drive member 25 provides power for the rotation of the flipping disk 21, and its output end is connected to the first transmission member 26. The first transmission member 26 transmits power from the first drive member 25 to the end plate 211, thereby realizing the rotation action of the flipping disk 21 and improving the smoothness and accuracy of the flipping action. In addition, the first drive member 25 is fixedly set on one side of the disk base 24, which facilitates the installation and maintenance of the first drive member 25.

[0048] Specifically, the first drive unit 25 typically uses a power source such as a motor, which can provide sufficient torque to drive the tilting plate 21 to rotate 180°. By properly selecting the power and speed of the first drive unit 25, the tilting action can be ensured to be completed smoothly within the predetermined time, while avoiding equipment failure due to insufficient power or overload.

[0049] Based on the above embodiments, one end plate 211 is provided with a protrusion on its end face away from the other end plate 211, so that the side of the end plate 211 forms a groove 211a, and the first transmission member 26 is assembled in the groove 211a. The protrusion structure not only increases the structural strength of the end plate 211, but also provides a suitable assembly position for the first driving member 25. With the first transmission member 26 assembled in the groove 211a, the first driving member 25 can be tightly combined with the end plate 211 to form an integrated structure, optimize the spatial layout, and improve the compactness and stability of the entire mold flipping mechanism 20.

[0050] Specifically, the first transmission component 26 can adopt various methods such as gear transmission, chain transmission or belt transmission, and the specific choice depends on the power transmission requirements and space constraints in the actual application.

[0051] Based on the above embodiments, the hoisting frame 11 includes a guide frame 111, a first movable support 112, and a second movable support 113. The top and bottom four corners of the guide frame 111 are fixedly connected to the inner side of the tilting disk 21. The first movable support 112 and the second movable support 113 are slidably disposed in the guide frame 111 and are fixedly connected to the first conveying assembly 22 and the second conveying assembly 23, respectively. The guide frame 111 provides a stable sliding track for the first movable support 112 and the second movable support 113. Its top and bottom are fixedly connected to the inner side of the tilting disk 21, so that the entire hoisting frame... The body 11 forms a stable frame structure within the tilting plate 21, ensuring accurate movement of the sand box and cover plate during the demolding process and preventing deviation or shaking. The first movable support 112 moves up and down, driving the first conveying component 22 to lift and lower the sand box, ensuring a tight fit between the sand box and the cover plate and the accuracy of subsequent separation operations. The second movable support 113 can adjust its height to change the height of the cover plate in the demolding station 02, ensuring that it is on the same working plane as the hardening station 01 and the transfer station 03, thus guaranteeing the stability of the conveying process.

[0052] Based on the above embodiments, the guide frame 111 has four guide rods 111a arranged vertically, with both ends fixedly connected to the top and bottom of the guide frame 111, respectively. The first movable support 112 and the second movable support 113 each have guide rings 112a at their four corners. Each guide ring 112a is sleeved on the corresponding guide rod 111a and slides along the axial direction of the guide rod 111a. The guide rods 111a provide a stable sliding track for the first movable support 112 and the second movable support 113. Their vertical arrangement ensures that the first movable support 112 or the second movable support 113 maintains an accurate vertical direction during movement, avoiding deviation or swaying. The guide rings 112a, located at the four corners of the first movable support 112 and the second movable support 113 and sleeved on the guide rods 111a, not only provide guidance, allowing the movable support to slide smoothly along the axial direction of the guide rods 111a, but also reduce friction between the movable support and the guide rods 111a, extending the service life of the equipment.

[0053] Based on the above embodiments, the first movable support 112 and the second movable support 113 are frame structures connected longitudinally and transversely, providing sufficient strength and stability, and providing assembly space for the first conveying component 22 or the second conveying component 23; a plurality of assembly holes 112b are evenly distributed in the middle plate of the frame structure, and the first conveying component 22 and the second conveying component 23 are fixedly connected to the first movable support 112 and the second movable support 113 through the assembly holes 112b and fasteners; the fasteners firmly fix the first conveying component 22 and the second conveying component 23 to the movable support through the assembly holes 112b, ensuring that the conveying components will not loosen or shift during the demolding process, thus improving the stability of the demolding operation; in addition, according to the different specifications of the conveying components, appropriate assembly holes 112b can be selected for connection, so that the movable support can adapt to conveying components of various sizes, improving the versatility and flexibility of the equipment.

[0054] Based on the above embodiments, the first conveying assembly 22 and the second conveying assembly 23 have the same structure, both including a second driving member 221, a conveying frame 222, and a plurality of conveying rollers 223. The conveying frame 222 is fixedly connected to the hoisting frame 11, and the plurality of conveying rollers 223 are arranged in parallel in the conveying frame 222 to receive sand boxes or cover plates. The second driving member 221 is fixedly disposed on one side of the conveying frame 222 to drive the plurality of conveying rollers 223 to rotate and convey sand boxes or cover plates. The second driving member 221 serves as the power source of the conveying assembly, and is transmitted through a transmission mechanism. The structure transmits power to each conveying roller 223, enabling the conveying roller 223 to rotate smoothly and realize the conveying of sand boxes or cover plates. The conveying frame 222 is the main structure of the conveying assembly. It is fixedly connected to the hoisting frame 11 to ensure that it maintains a stable position and posture during the conveying process. It also has a certain strength and rigidity to withstand the weight of the sand box or cover plate and the forces generated during the conveying process. The conveying rollers 223 are arranged in parallel in the conveying frame 222 and directly contact the sand box or cover plate to realize the receiving and conveying functions, and ensure the smoothness and durability of the conveying process.

[0055] Based on the above embodiment, a positioning block 224 is also provided on the conveying frame 222. The positioning block 224 is arranged facing the inside of the conveying frame 222 and located between the gaps of adjacent conveying rollers 223. The positioning block 224 is used to accurately position and limit the sand box or cover plate during the conveying process. When the sand box or cover plate is placed on the conveying roller 223, the positioning block 224 can constrain it from the side to prevent it from shifting or shaking laterally during the conveying process, ensuring the stability of the sand box or cover plate during the conveying process and improving the accuracy and reliability of the conveying.
