In order to assemble the multiple sand core splits into an integral sand core body, the existing core assembly jig usually includes a workbench, a fixed seat is provided at one end of the top of the workbench, and a plurality of movable seats are evenly distributed on the workbench located on one side of the fixed seat. The corresponding sand core splits can be placed on the fixed seat and the movable seat. When the sand core splits on the multiple movable seats and the sand core splits on the fixed seat are assembled, the movable seat is slid and moved toward one side of the fixed seat in turn. After that, the sand core split on the fixed seat is first assembled together with the sand core split on the nearest movable seat, and the sand core splits on the other movable seats are also moved together in turn, thereby realizing the assembly of the multiple sand core splits into an integral sand core body.
[0003] For example, the patent document with the patent announcement number of 207325889U and the patent name of a sand core assembly mold, in which a sliding seat for carrying a sand core split is arranged on the top of the workbench, main pin holes are respectively arranged at both ends of the sliding seat, and a latch device is provided at both ends of each sliding seat on the workbench, the latch device includes a pin body that can extend to one side of the sliding seat, and the sliding seats slide toward one side of the fixed seat in turn and move together so that the pin bodies can be inserted into the corresponding main pin holes.
[0004] During the use of the above patent, since the sand core split on the movable seat is movable, even if it is close together, when the worker inserts the screw inside it, due to operational errors, the screw is easy to push the sand core split open, and the material of the sand core split is relatively soft, which can easily cause the sand core to be misplaced and broken, thereby affecting the casting quality of the entire product. With the increase in output and material costs, such problems become more prominent. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] See also Figure 1-Figure 3 The utility model provides a supporting device for optimizing a cylinder head core assembly jig, comprising a supporting base plate 1 and a plurality of core assembly jig bearing seats 2; a fixed seat 11 is fixedly arranged on the end face of the supporting base plate 1, a guide slide rail 12 is arranged between adjacent fixed seats 11, and each core assembly jig bearing seat 2 is slidably sleeved on the guide slide rail 12; since the volume of some castings is large, in order to ensure the processing accuracy, a plurality of core assembly jig bearing seats 2 are pre-arranged, the sand core is placed on the core assembly jig bearing seat 2, and the connection accuracy is ensured by the guide slide rail 12.
[0025] The core assembly jig bearing seat 2 near the two ends of the guide rail 12 is also provided with a limiting device 3, which includes a connecting seat 31, a limiting rod 32 and a limiting block 33; the connecting seat 31 is fixedly arranged on the outer side of the core assembly jig bearing seat 2, the limiting rod 32 is hinged to the connecting seat 31 through a pin, the limiting block 33 is fixedly connected to the supporting bottom plate 1, and the limiting block 33 is used to abut against the limiting rod 32. During the casting process of the engine cylinder head assembly, it is necessary to insert a screw into the sand core. At this time, it is necessary to temporarily fix the core assembly jig bearing seat 2 at both ends, lift the limiting rod 32 to a certain height, move the core assembly jig bearing seat 2 to a certain position, and then clamp the limiting rod 32 into the limiting block 33 to fix the core assembly jig bearing seat 2. At this time, if the screw is inserted into the sand core again, the sand core will not be broken by the screw when the screw is inserted due to position movement.
[0026] The utility model has two sets of guide rails 12, which are parallel and perpendicular to the length direction of the core assembly mold support seat 2. The guide rails 12 are generally used in pairs, and the core assembly mold support seat 2 is sleeved on the guide rails 12 to ensure stability during movement. The guide rails 12 can generally also directly use guide light bars, which have higher precision and stronger load-bearing capacity and are suitable for multiple reciprocating sliding.
[0027] The top of the limiting block 33 of the present invention is also provided with a notch 331, the notch 331 is close to one side of the limiting rod 32, and the notch 331 is used to clamp the limiting rod 32. Figure 3 The limit block 33 is generally fixed directly to the corresponding position of the support base plate 1 through a hexagon socket nut. Since one end of the limit rod 32 is hinged on the connecting seat 31 and rotates, in order to facilitate the abutment and temporary fixation of the limit rod 32, a notch 331 is set on the top of the limit block 33 toward the side of the limit rod 32. The notch 331 allows a portion of the limit block 33 to be recessed, which is convenient for directly fixing the limit rod 32 and will not hinder the installation of the hexagon socket bolt. When producing the cylinder head assembly, it is generally only necessary to prevent the two outermost core assembly mold bearing seats 2 from sliding toward both ends to meet the use requirements after fixation.
[0028] Each core assembly mold support seat 2 at the end of the utility model is provided with two connecting seats 31. In actual operation, the operator generally uses two hands to exert force at the same time, so the core assembly mold support seat 2 at the end is provided with two limit devices 3, which will make the operation more convenient and more stable.
[0029] The connection seat 31 of the utility model is located outside the guide rail 12, close to the end of the core assembly mold bearing seat 2. In order to facilitate installation, the connection seat 31 is generally fixed to the outside of the guide rail 12, so that workers can easily fix the limit rod 32 during operation.
[0030] The core assembly mold support seat 2 of the present invention is also provided with an arc handle 21. The arc handle 21 is used to drive the corresponding core assembly mold support seat 2 to slide, and the arc handle 21 is generally arranged obliquely upward to prevent interference.
[0031] The extension length of each limit rod 32 of the utility model is the same. After being fixed, the position of each core assembly jig bearing seat 2 can be guaranteed to be consistent, so that the position of the sand core after docking is consistent, which is conducive to ensuring processing accuracy.
[0032] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
