Problems solved by technology
Among them, due to too many human factors involved in the core setting, coupled with the fact that there are many sand cores in the cylinder body, the volume is large, the core head fit error is large, and the sand cores are loose after repeated core setting, it is difficult to guarantee in practice. The stability of sand core positioning meets the technical requirements, which also results in low efficiency of core setting and high labor intensity, which is not conducive to efficient production

The invention discloses a cylinder body core-setting device and an application method of the cylinder body core-setting device. A plurality of sets of sand cores are simultaneously positioned through the matching of a cylinder body core assembly mould bed and the cylinder body core-setting device arranged above the cylinder body core assembly mould bed. According to the cylinder body core-setting device and the application method of the cylinder body core-setting device, an original single core print positioning core-setting method is changed into a double synchronous mechanical pin positioning core-setting method, the stability of core-setting positioning is improved, the core-setting frequency is effectively reduced, mechanical operation and automatic operation are facilitated at the same time, work efficiency can be improved, labor intensity is relieved, and an excellent promoting effects is provided for practical production.
Description
technical field [0001] The invention relates to the technical field of core setting for sand molding of a cylinder block, in particular to a core setting device for a cylinder block and an application method thereof. Background technique [0002] In the current field of cylinder core lowering device production, the process of positioning the core head and manually supporting the lower core with a crane is usually used. The implementation steps of this method are: manual (or crane) holding (lifting) For the sand core, visually locate the core head and the positioning core seat of the shape, hold the sand core and lower the core, and use the fixed head to position or correct the main core during the process. Among them, due to too many human factors involved in core setting, coupled with the fact that there are many sand cores in the cylinder body, the volume is large, the core head fit error is large, and the sand cores are loose after repeated core setting, it is difficult t...
