Abstract
Abstract The invention provides a positioning chaplet which comprises a chaplet body, the center of the chaplet body is provided with a mounting hole in which a positioning device is disposed. The positioning chaplet is convenient for placement and can effectively position a sand core and prevent the sand core from deformation. ) 3
Description
D e s c r i p t io n POSITIONING CHAPLET Field of the invention The invention relates to the casting field, in particular to a positioning chaplet. Background of the invention As shown in figure 2, an external model 4 and a sand core 5 form a mould cavity 6, and in casting process, in order to prevent bending deformation of the long sand core 5, a chaplet body I is usually additionally arranged to increase application points of the sand core 5. As shown in figure 1, in the prior art, a chaplet body I is made into a solid metal block with smooth surface and arranged in a mould cavity 6 formed between a sand core 5 and an external model 4, the chaplet body I can be placed on a plane fairly well, but is difficult to be placed on a curved surface or a steeper surface, and moreover, the chaplet body I is easy to slide to be hard to support the sand core 5. Summary of the invention The object of the invention is to provide a positioning chaplet which is convenient for placement and can effectively position a sand core and prevent the sand core from deformation. In view of the above technical problems, the invention employs the following scheme: a positioning chaplet comprises a chaplet body, the center of the chaplet body is provided with a mounting hole in which a positioning device is disposed. Preferably, said positioning device is a positioning nail. The lower end of the D e s c r i p t io n positioning nail is hammered into a sand core to fix the chaplet body on the sand core, and the mounting is convenient. The invention has the following advantages: The technical scheme of the invention provides a positioning chaplet which is convenient for placement, effectively positions a sand core and prevents the sand core from deformation. Brief description of the drawings Figure 1 is a sectional view of the traditional chaplet; Figure 2 is a schematic diagram of the traditional chaplet in using state; Figure 3 is a sectional view of the invention; and Figure 4 is a schematic diagram of the invention in using state. Detailed description of the embodiment Referring to figure 3, a positioning chaplet comprises a chaplet body 1, the center of the chaplet body I is provided with a mounting hole 2 in which a positioning device 3 is disposed, and the positioning device 3 is a positioning nail. In practice application, referring to figure 4, the lower end of the positioning device 3 is hammered into a sand core 5 to fix the chaplet body I on the sand core 5, and then the sand core 5 is sleeved in an external model 4 such that the sand core 5 has a fixed application point. The chaplet body I is convenient for mounting and can be placed at any position, thereby effectively positioning the sand core and preventing the sand core from deformation.
