[0001] The present application relates to the field of casting technology, and in particular to a sand core repair and positioning device. Background Art

[0002] Sand core is a kind of casting auxiliary material used to form internal cavity or complex structure in the casting process. Sand core is made of sand and resin with certain requirements through a certain process to form a certain geometric shape to form a casting cavity. After the sand core is made, it is usually trimmed to remove the blank seam and excess material at the parting surface of the sand core or the position of the core rod.

[0003] At present, sand core repair often uses a core repair positioning jig dedicated to a certain product. A certain number of positioning blocks are designed on the jig according to the product structure. The length and width positions of the sand core are fixed by the positioning blocks. The corresponding positioning jig is replaced according to the product change.

[0004] However, the positioning block is relatively fixed and is usually a special tooling for a certain product. It is suitable for production lines with a small number of product types and a large output. However, on production lines with multiple varieties and small batches, product changeover requires manual switching of sand core positioning jigs and cleaning of loose sand on the jigs, and requires a large amount of storage space for positioning jigs, resulting in low production efficiency and high labor intensity.

[0027] The sand core repair positioning device provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0028] The present application discloses a sand core repair positioning device. Figure 1 and Figure 2 As shown, the sand core repair positioning device includes a workbench 2, a plurality of slide grooves 7 and a plurality of limit blocks 5.

[0029] One side of the workbench 2 forms a sand core supporting surface.

[0030] A plurality of slide grooves 7 are opened on the workbench 2 on the sand core supporting surface, and the plurality of slide grooves 7 are dispersedly arranged on the sand core supporting surface.

[0031] A plurality of limit blocks 5 are located on the sand core support surface, and the plurality of limit blocks 5 correspond one-to-one to the plurality of slide grooves 7 . Each limit block 5 is slidably connected to the corresponding slide groove 7 , and the limit block 5 can be positioned at any position in the slide groove 7 .

[0032] By using the sand core repair positioning device in the technical solution, when repairing the sand core, the sand core is placed on the sand core supporting surface of the workbench 2, and at least part of the multiple limit blocks 5 are selected according to the type of sand core, that is, the shape and size of the sand core, and the position of the limit blocks 5 of this part in the corresponding slide groove 7 is finely adjusted to block and limit multiple positions around the sand core, and then the sand core can be repaired. The sand core repair positioning device can realize the positioning of various types of sand cores by distributing the limit blocks 5 and the slide groove 7 in groups on the sand core supporting surface, and cooperating with the sliding and locking of the limit blocks 5 in the length direction of the slide groove 7, thereby improving the applicability of the sand core repair positioning device, reducing space occupancy, improving production efficiency, and reducing labor intensity.

[0033] In some embodiments of the present invention, Figure 2 As shown, the plurality of slide grooves 7 include a plurality of first slide grooves and a plurality of second slide grooves, and the first slide grooves and the second slide grooves are perpendicular to each other.

[0034] In this embodiment, it can be understood that the plurality of slide grooves 7 are divided into two groups, one group is used as the first slide grooves, and the other group is used as the second slide grooves perpendicular to the first slide grooves.

[0035] Furthermore, the first chute and the second chute match each other and are arranged on the workbench 2 in a circle-by-circle manner. Specifically, a workbench 2 of a suitable size can be selected and the first chute and the second chute can be configured according to the maximum and minimum sizes of the sand cores to be used.

[0036] It can be understood that, through the mutually perpendicular first slide groove and the second slide groove, the limit block 5 can position the sand core in the horizontal direction and the vertical direction respectively, and has a large adjustment range, which can be applicable to sand cores of more specifications.

[0037] In some embodiments of the present invention, Figure 2 and 3 As shown, each chute 7 is provided with an independent number.

[0038] For example, in this embodiment, the plurality of first chutes are numbered as L01, L11, etc., and the plurality of second chutes are numbered as H11, H12, etc.

[0039] According to the different types of sand cores, the first chute and the second chute specifically selected for the sand core are sorted and recorded in a numbered manner. When the corresponding sand core is repaired, the chute 7 with the appropriate number can be quickly found, so that the limit block 5 thereon can be used to fix the sand core, thereby improving the fixing efficiency of the sand core.

[0040] In some embodiments of the present invention, Figure 3 As shown, each slide groove 7 is provided with a scale 8 along its length direction.

[0041] According to the different types of sand cores, the first slide groove and the second slide groove specifically selected for the sand core are sorted and recorded in a numbered manner, and after each limit block 5 fixes the sand core, the scales of each limit block 5 in the corresponding slide groove 7 are sorted and recorded. When the corresponding sand core is repaired, not only can the slide groove 7 with a suitable number be found quickly, but also each limit block 5 can be quickly positioned, thereby further improving the fixing efficiency of the sand core.

[0042] In some embodiments of the present invention, Figure 4 As shown, the slide groove 7 passes through the workbench 2, and a slider that slidably cooperates with the slide groove 7 is fixed to the side of the limit block 5 close to the slide groove 7. The slider is provided with a fixing member 6 for locking the slider and the workbench 2.

[0043] In this embodiment, the limit block 5 is slidably connected to the slide groove 7 through the slider, and after the limit block 5 moves to a suitable position, the position of the slider and the limit block 5 is locked by the fixing member 6 to support the sand core.

[0044] Furthermore, the fixing member 6 includes but is not limited to a tightening screw, a pin, and the like.

[0045] Furthermore, the slider and the limit block 5 are integrally connected to the slide groove 7 in a detachable manner, so that when a larger sand core is fixed, the limit block 5 within the coverage of the sand core can be removed to avoid bumping the sand core.

[0046] In some embodiments of the present invention, Figure 3 As shown, a plurality of through holes 9 are provided on the workbench 2 , and the plurality of through holes 9 are dispersedly arranged on the workbench 2 .

[0047] By arranging the through hole 9 on the workbench 2, when the sand core is repaired on the sand core supporting surface, the waste generated can fall through the through hole 9 to the back side of the workbench 2, and after the repair is completed, the waste remaining on the sand core supporting surface can be cleaned to the back side of the workbench 2 through the through hole 9, thereby facilitating the repair of the next sand core.

[0048] It should be understood that the plurality of through holes 9 can be arranged on the workbench 2 in an array manner, and it is sufficient to ensure that the through holes 9 and the slide grooves 7 are staggered with each other.

[0049] In some embodiments of the present invention, Figure 4 As shown, a drain groove 4 is provided on the side of the workbench 2 away from the sand core supporting surface, and the drain groove 4 is opened on the side close to the workbench 2 , and a plurality of through holes 9 are located within the opening range of the drain groove 4 .

[0050] The waste materials dropped from the through hole 9 can be collected through the drain groove 4 to avoid the waste materials being scattered on the ground, thereby ensuring the comfort of the working environment.

[0051] In some embodiments of the present invention, Figure 4 As shown, the drain groove 4 is opened at a side away from the workbench 2 , and the cross-sectional size of the drain groove 4 gradually decreases from the side close to the workbench 2 to the side away from the workbench 2 .

[0052] Furthermore, a chip collecting trolley is provided on the side of the drain trough 4 away from the workbench 2 .

[0053] In this embodiment, the waste falling from the through hole 9 will be collected in the chip collecting trolley through the leakage groove 4, and after the chip collecting trolley is full of waste, the waste can be transported out by the chip collecting trolley, so as to facilitate the subsequent treatment of the waste.

[0054] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a bracket 1 is fixed to the side of the workbench 2 away from the sand core supporting surface.

[0055] In this embodiment, a column is fixed at each of the four end corners of the workbench 2 to form a bracket 1 to support the workbench 2 .

[0056] Furthermore, a cross beam 3 is fixed between every two upright posts to improve the stability of the bracket 1 .

[0057] Furthermore, the drain trough 4 is located within the range surrounded by each column and is fixed by the crossbeam 3 .

[0058] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model.
