Core box loose piece automatic mold release device

Abstract

The invention provides a core box loose piece automatic mold release device. The automatic mold release device includes a static core box and a moving core box, wherein loose pieces are arranged between the static core box and the moving core box, and a pair of fixed rollers are arranged between loose pieces to constitute a loose piece assembly, which is embedded into the moving core box via a guide rail; a slipper guide rod is arranged between the two rollers, and is fixed on a guide rod fixation plate in inclined manner, and the guide rod fixation plate is fixed on the static core box via a bolt; and the static core box is provided in interior with an automatic core pushing device. The automatic mold release device drives the loose piece via a slope guide rod to move in direction perpendicular to the device, automatically pushes loose piece to predetermined working position during core making process, can realize automatic mold release of the loose piece from sand core to return to predetermined position, has convenience and rapidity, fundamentally overcomes defect of take-out of loose piece in conventional manual manner, and facilitates mechanical batch production and quality stabilization.

Description

technical field [0001] The invention relates to the field of mechanical casting, in particular to an automatic demoulding device for loose blocks of core boxes. Background technique [0002] Due to the different structures of castings, it is inevitable to use live blocks in the core-making process of castings, such as figure 1 As shown, it is a traditional and representative loose block use principle and production process. Since the product structure requires that the sand core 14 has two grooves and is perpendicular to the drawing direction, the loose block 13 must be used to meet the production requirements. From figure 1 It can be seen that after the upper core box 12 is taken out, the loose block 13 remains in the sand core 14, and the sand core 14 can be taken out from the lower core box 11 only after the loose block 13 must be taken out by hand; 14 In the early stage of production, the loose block 13 has to be assembled manually, and the upper core box 13 and the low...

[0002] Due to the different structures of castings, it is inevitable to use live blocks in the core-making process of castings, such as figure 1 As shown, it is a traditional and representative loose block use principle and production process. Since the product structure requires that the sand core 14 has two grooves and is perpendicular to the drawing direction, the loose block 13 must be used to meet the production requirements. From figure 1 It can be seen that after the upper core box 12 is taken out, the loose block 13 remains in the sand core 14, and the sand core 14 can be taken out from the lower core box 11 only after the loose block 13 must be taken out by hand; 14 In the early stage of production, the loose block 13 has to be assembled manually, and the upper core box 13 and the lower core box 11 are connected together using positioning pins 15. The manual speed seriously affects the production efficiency, and mechanized production cannot be carried out, nor can it meet mass production. It is not conducive to the stability and improvement of sand core quality
