Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

Fig. 1 is a schematic view of a core setting alignment mark arrangement for a sand core in a casting process according to an embodiment of the present invention. Fig. 2 is another schematic view of a core setting alignment mark configuration of a sand core during a casting process according to an embodiment of the present invention.

As shown in fig. 1 to 2, a core setting alignment mark structure for a sand core in a casting process according to a preferred embodiment of the present invention includes a mold module 1 and a sand core 2. The casting mold block 1 is provided with a casting main marking 11 and a casting limit marking 13. And the sand core 2 is placed in the casting module 1, and a sand core main marking 21 and a sand core limit marking 23 are arranged on the sand core 2. The positions of the casting main marking 11, the sand core main marking 21, the casting limit marking 13 and the sand core limit marking 23 can be used for judging whether the lower core is completely aligned or not, and the deviation size of the lower core can be judged.

In an embodiment of the present invention, the mold module 1 is further provided with a mold auxiliary mark 12. The number of the molding auxiliary markings 12 is plural, and the number of the molding limit markings 13 is plural. The plurality of casting mold auxiliary marks 12 are respectively located on both sides of the casting mold main mark 11, the plurality of casting mold limit marks 13 are respectively located on both sides of the casting mold main mark 11, and the casting mold limit marks 13 are located farther from the casting mold main mark 11 than the casting mold auxiliary marks 12.

In an embodiment of the present invention, the sand core 2 is further provided with a sand core auxiliary marking 22. The number of the core auxiliary marks 22 is plural, and the number of the core limit marks 23 is plural. The multiple sand core auxiliary marking lines 22 are respectively positioned at two sides of the sand core main marking line 21, the multiple sand core limit marking lines 23 are respectively positioned at two sides of the sand core main marking line 21, and the sand core limit marking lines 23 are far away from the sand core main marking line 21 compared with the sand core auxiliary marking lines 22.

In practical application, the utility model discloses a marking structure is adjusted well to core under casting process psammitolite, makes main marking, supplementary (warning) marking and limit marking respectively on psammitolite 2 and casting mould module 1, has both possessed old-fashioned marking and has detected the function that whether core is adjusted well completely under the psammitolite 2, can audio-visually detect out the size range of psammitolite 2 core deviation down simultaneously, is convenient for judge whether size deviation surpasss the technological requirement, provides the judgement foundation for production process quality clearance and on-the-spot technology adjustment. A single marking line is not used for roughly judging the core setting deviation condition, but an auxiliary marking line and a limit marking line are additionally arranged on two sides of the main marking line to assist production personnel in judging the specific core setting deviation size. According to specific needs, the auxiliary marked lines can be provided with a plurality of auxiliary marked lines, or only limit marked lines can be directly arranged without the auxiliary marked lines. When the mold block 1 (mold) is used to form the mold mark, the position of the sand core limit mark 23 with respect to the mold limit mark 13 is formed with a dimension deviated to the main mark side B, and the sand core auxiliary mark 22 with respect to the corresponding mold auxiliary mark 12 is formed with a dimension deviated to the main mark side a. Wherein dimension B is the maximum tolerance value of the core setting deviation allowed in the production process, and dimension A is the warning tolerance value smaller than B. After the core is placed in the production process, the marking deviation condition is read manually, so that the specific size range value of the core placement deviation can be directly judged without other tools, and accurate response can be made. If the sand core main marking 21 is aligned with the casting main marking 11, the lower core complete alignment deviation is zero. If the sand core main marking 21 is not aligned with the casting mould main marking 11, the core setting deviation range can be judged according to the auxiliary markings on the two sides. For example, as shown in fig. 2, the main marking line 21 of the sand core is deviated to the left relative to the main marking line 11 of the casting mold, the auxiliary marking line on the left side of the sand core is deviated outside the auxiliary marking line 12 of the corresponding casting mold, and the limit marking line on the left side of the sand core is not deviated outside the limit marking line 13 of the casting mold, so that the sand core after core setting can be directly judged to be deviated to the left relative to the casting mold, and the deviation value is between a and B.

In a word, the utility model discloses a marking structure is adjusted well to core under casting process psammitolite, can confirm down the core fast and adjust well completely, can also audio-visual judgement down the core deviation size, improved work efficiency, be convenient for in actual production, the core deviation condition under the on-the-spot operating personnel can audio-visual observation, quick and accurate reply of making.
