Problems solved by technology
The mold is divided into outer mold (term: shape), inner mold (term: core joint), in a set of molds (referring to: medium and large castings), the number of core joints should account for 60% to 90% of the total mold set. %, in prior art, such as figure 1 1. Each core must be equipped with a core platform (term: bottom plate), which cannot be interchanged, and the outer positioning block of the core is fixed with the bottom plate as a whole, and cannot be disassembled. The positioning block should be 2-4cm higher than the bottom plate, so the existing technology There are two major disadvantages in the manufacture and use of cores
[0003] 1. The positioning block affects the disassembly and assembly of the core, which increases the workload of the caster. It is extremely inconvenient to lift the core, turn the core, remove the core and close the plug.
[0004] 2. Each core is equipped with a bottom plate, the amount of the bottom plate is too large, and the waste is serious

Embodiment Construction
[0015] Depend on figure 2 It can be seen that the features of the present invention are built-in positioning and a shared platform. First, the built-in positioning plate B4 is placed on the shared base plate B1 (common platform), and then the core block 3 is respectively placed on the base plate B1, and the two ends of the positioning plate B4 are placed on the top of the shared base plate B1 (common platform). Put the core joint 2 on the bottom plate B1, position the two sides of the plate B4, and finally fasten the two ends of the core joint 2 with bolts 5 to form a whole core joint, then fill the sand for molding, and remove the fastening bolts after molding , core-joint 2 and core-joint block 3 can be freely disassembled parallel to the outside, without the need to use the process of hanging and turning the core.
[0016] figure 2 The pin 6 in the core is used in the handling and storage process of the core. The core 2 and the core block 3 are connected with the built-i...

Abstract
The invention relates to manufacture of and improvement of construction processes of casting moulds. According to the improved method, a built-in locating plate is used. A conventional mode of one inner mould and one bottom plate is eliminated and a shared platform is adopted. The improved casting mould process method has the beneficial effect of saving labor force, materials, and cost.
Description
technical field [0001] The invention relates to the improvement of the mold process in the foundry industry, and is suitable for the manufacture of the mold for casting and the improvement of the use method of the mold. Background technique [0002] At present, the molds in the foundry industry are mainly metal molds and wooden molds. The mold is divided into outer mold (term: shape), inner mold (term: core joint), in a set of molds (referring to: medium and large castings), the number of core joints should account for 60% to 90% of the total mold set. %, in prior art, such as figure 1 1. Each core must be equipped with a core platform (term: bottom plate), which cannot be interchanged, and the outer positioning block of the core is fixed with the bottom plate as a whole, and cannot be disassembled. The positioning block should be 2-4cm higher than the bottom plate, so the existing technology There are two major disadvantages in the manufacture and use of cores. [0003] ...
