DETAILED DESCRIPTION

[0028] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in combination with the drawings and examples. Example one

[0029] As Figures 1-2 And Figure 7 A water pump casting manufacturing equipment, comprising an upper box 1 and a lower box 2, a connecting mechanism is arranged between the upper box 1 and the lower box 2;

[0030] The connecting mechanism comprises an upper frame 11, a lower frame 21 and a positioning assembly, the upper frame 11 is matched with the opening of the upper box 1, the lower frame 21 is matched with the opening of the lower box 2, the number of the positioning assembly is several and is uniformly distributed on the four sides of the lower frame 21, the upper frame 11 is provided with a connecting hole 12 matched with the positioning assembly;

[0031] The positioning assembly comprises an outer column 3, a synchronization plate 31, a reset spring 32 and a plurality of limiting spring sheets 33, the outer column 3 is arranged on the upper end of the lower frame 21 and the lower frame 21 is provided with a corresponding through hole 34, the outer column 3 is provided with a plurality of movable grooves 35 on the side surface, the synchronization plate 31 is slidably arranged in the outer column 3 and extends out through the movable grooves 35, the reset spring 32 is arranged between the reverse step of the through hole 34 and the lower end of the synchronization plate 31, a plurality of limiting spring sheets 33 are elastically connected with the upper end of the synchronization plate 31 and correspond to a plurality of movable grooves 35 one by one, the thickness of the upper frame 11 is equal to the distance between the limiting spring sheet 33 and the synchronization plate 31, and the lower frame 21 is provided with a recessed groove 36 matched with the synchronization plate 31;

[0032] The upper box 1 is further provided with an unlocking frame 37 matched with the positioning assembly, and the unlocking frame 37 is matched with the planar projection of the upper frame 11.

[0033] In the sand casting process, the sand is placed in the upper box 1 and the lower box 2 according to the process requirements, and the mold is closed and the sand is poured after preparation. The connecting mechanism shell plays a role in positioning and fixing during the mold closing process. When the upper box 1 is closed to the lower box 2, the connecting hole 12 on the upper positioning frame 11 of the upper box 1 is aligned with the outer column 3 at the corresponding position on the lower positioning frame 21, and then the upper positioning frame 11 is lowered until it overlaps the lower positioning frame 21. During the connecting process, the connecting hole 12 pushes the sliding connection of the synchronous plate 31 in the outer column 3, so that the synchronous plate 31 moves downward and drives the several limiting springs 33 to move downward. In the initial state, the synchronous plate 31 is located at the uppermost side of the movable groove 35, and the limiting spring 33 is also accommodated in the outer column 3. When the synchronous plate 31 is pushed downward, the limiting spring 33 will also move downward. In the static state, the limiting spring 33 will flip away from the axis of the outer column 3 until the limiting spring 33 completely corresponds to the movable groove 35. At this time, the limiting spring 33 flips outward to extend out of the movable groove 35. The outer side of the upper end of the limiting spring 33 is a slope from top to bottom away from the axis of the outer column 3, which can facilitate the installation and connection of the upper positioning frame 11. The distance between the abutting lower end surface of the limiting spring 33 and the upper end surface of the lower positioning frame 21 matches the thickness of the upper positioning frame 11, so that the upper positioning frame 11 can be effectively limited and abutted after connection. The connection method is convenient and fast. After connection, the upper positioning frame 11 is limited in the planar direction by the outer column 3 and in the longitudinal direction by the limiting spring 33, thereby achieving stable connection and position limitation of the upper box 1 and the lower box 2, ensuring that the sand cavity does not move, and the castings after subsequent sand pouring are regular. The setting of the inward recess 36 can ensure that the synchronous plate 31 does not affect the complete closing of the upper box 1 and the lower box 2.

[0034] During the sand pouring process after connection, several positioning assemblies cooperate to achieve stable limiting connection. Even if one of the positioning assemblies fails to limit, the upper positioning frame 11 and the lower positioning frame 21 still remain connected to avoid opening and displacement. At the same time, by using the unlocking frame 37, only the limiting spring 33 of several positioning assemblies needs to be retracted into the outer column 3 through the same positioning connection of the upper positioning frame 11 during the unlocking operation, so that the upper box 1 can be unlocked and lifted at the same time to complete the opening operation, thereby effectively improving the stability of production and the quality of products.

[0035] The vertical section of the limiting spring 33 is in a 7-shaped structure. Example Two

[0036] As shown in Figures 3-4 Further improvement based on example one, a compensator is further provided in the positioning assembly. The compensator includes an adjusting member and a pressure member. The lower positioning frame 21 is provided with a square cavity matched with several positioning assemblies. The adjusting member is arranged in the square cavity, and the pressure member is arranged in the middle part of the outer column 3 and connected with the corresponding adjusting member.

[0037] The pressure piece comprises a screw rod 4, an extension rod 41, a limiting shell 42 and a pressure mark 43, a circular hole 44 is formed in the middle of the synchronization plate 31, the screw rod 4 is rotationally connected with the upper end of the outer column 3 and connected with the extension rod 41 through the circular hole 44, the extension rod 41 is drivingly connected with the adjusting piece, the limiting shell 42 is fixedly connected with the inner upper end of the outer column 3 and sleeved on the outer side of the screw rod 4, vertical strip openings 45 are formed in the side of the limiting shell 42 and matched with the number of the limiting elastic sheets 33 and the length of the limiting shell 42 is matched with the length of the screw rod 4, the pressure mark 43 is threadedly connected with the screw rod 4 and extends out through the vertical strip openings.

[0038] The pressure mark 43 comprises a connecting ring and a plurality of limiting feet, the connecting ring is threadedly connected with the screw rod 4, the limiting feet are evenly arranged on the side of the connecting ring and extend out through the vertical strip openings, and the limiting feet are matched with the limiting elastic sheets 33.

[0039] The adjusting piece comprises a plurality of transmission gears 5, a transmission chain 51 and an adjusting handle 52, the transmission gears 5 are rotationally arranged in the square cavity and one-to-one correspond to the alignment assemblies, the transmission chain 51 is arranged between the transmission gears 5, and the adjusting handle 52 is connected with one of the transmission gears 5 and located below the lower frame 21.

[0040] In order to ensure that the upper box 1 and the lower box 2 can be more effectively closed, improve the sealing effect and avoid accidental opening, after the upper frame 11 and the lower frame 21 are connected and closed, the limiting shell 42 is rotated by the corresponding transmission gear 5 through the adjusting handle 52, because the transmission gears 5 are connected by the transmission chain 51, when the transmission gear 5 is rotated by the adjusting handle 52, all the transmission gears 5 will start to rotate, and then the corresponding screw rod 4 is driven to rotate by the corresponding extension rod 41, at this time, the pressure mark 43 connected with the screw rod 4 will move according to the rotating direction of the screw rod 4 under the limitation of the limiting shell 42, in the above case, the pressure mark 43 moves downward to press the synchronization plate 31, so that the synchronization plate 31 drives the limiting elastic sheet 33 to further press the upper frame 11 and further limits the position of the synchronization plate 31, the limiting elastic sheet 33 cannot be flipped through the abutment of the limiting feet, so that the unlocking operation through the unlocking frame 37 is not possible, thereby avoiding accidental opening and improving stability.

[0041] Correspondingly, the pressure mark 43 only needs to be reset when unlocking, the structure is stable, the operation is convenient, and the production is facilitated. Example Three

[0042] As Figures 5-6Further improvement based on embodiment two, the connecting mechanism further comprises a side lock assembly between the upper frame 11 and the lower frame 21, the side lock assembly comprises a traction rope 6, a guide block 61 and a lock, the guide block 61 is arranged on the side of the lower frame 21 and matches the position of the alignment assembly, the lock is arranged on the side of the guide block 61 and matches the upper frame 11, a wire slot 63 communicating with the outer column 3 is arranged between the guide block 61 and the lower frame 21, one end of the traction rope 6 is connected with one of the limiting feet, the other end of the traction rope 6 is slidably connected with the lock.

[0043] The lock comprises a sliding block 7, a lock tongue 71 and a pressure spring 72, the guide block 61 is provided with a stepped cavity 73 opening towards the upper frame 11, the sliding block 7 is slidably arranged in the stepped cavity 73, the lock tongue 71 is connected with the sliding block 7 and extends out of the stepped cavity 73, the inclined end of the lock tongue 71 faces upward, the other end of the traction rope 6 is fixedly connected with the other end of the sliding block 7, the pressure spring 72 is sleeved on the traction rope 6 and located in the stepped cavity 73, and the upper frame 11 is provided with a limiting groove 74 matching the lock tongue 71.

[0044] The guide block 61 protrudes from the upper end surface of the lower frame 21, and the guide block 61 is inclined downward towards the end of the upper box 1.

[0045] In order to further improve the stability of the connection between the upper box 1 and the lower box 2 and avoid displacement, the side lock assembly further limits the connection between the upper frame 11 and the lower frame 21 during the connection assembly process, and the lock is retracted into the stepped cavity 73 of the guide block 61 under the limitation of the traction rope 6 and the pressure mark 43 in the static state, so that the installation of the upper frame 11 is not affected and the guide block 61 can guide and adjust the position of the upper plate, avoiding the impact of inaccurate alignment on the outer column 3 and affecting the fixing of the sand mold, and improving the stability.

[0046] When the upper plate and the lower plate are connected and the synchronous plate 31 is further limited by the pressure mark 43, the pressure mark 43 will relax the pulling of the traction rope 6, thereby canceling the pulling of the sliding block 7, at this time, cooperating with the reset of the pressure spring 72, the lock tongue 71 will be deeply inserted into the limiting groove 74 to limit and block the upper frame 11, avoiding automatic opening;

[0047] When the box is opened, the synchronous plate 31 is directly unlocked by the pressure mark 43, and the unlocking method is convenient and fast.
