Technical field
The utility model relates to the fixture in the mesopore loam core of copper screw cast use peculiar to vessel, is particularly suitable for the mesopore loam core device for positioning and securing of middle-size and small-size copper FPP screw.
Background technology
The main effect of the copper screw mesopore of FPP peculiar to vessel loam core fixture (hereinafter to be referred as fixture) is that the mesopore loam core is stable in the seat of loam core.In the casting process, overcome the buoyancy and the impact of the high-temperature copper liquid that flows in the casting mold, guarantee that the loam core is not subjected to displacement.Thus, the reliability of loam core fastening means and fastener thereof directly influences the quality of product.
At present, the main element of the copper screw mesopore of domestic FPP of the same trade loam core fastener is: rising head case foundary weight, special-purpose pull bar etc.
In the same industry, most of producers often adopt the firm loam core of mode of combination weldment at home.During operation, professional welder's support must be arranged, need adjust series of processes operation such as rising head case foundary weight-adjustment loam core position-blanking-welding-fastening and could accomplish.30～60 fens clock times of whole operation process need, wherein, the welding sequence workload accounts for more than 60%. and whole operation operation workload increases, and operating efficiency is very low.Simultaneously, in the welding process, a large amount of welding slags get into the casting mold die cavity, the cleaning difficulty, and casting flaws such as cinder hole very easily appear in foundry goods.
The utility model content
The utility model provides spacing oar loam core device for positioning and securing, and the operational sequence workload that the utility model has solved the fastener existence of existing copper screw mesopore loam core is big, the problem that operating efficiency is very low.The utility model is on the basis of traditional fastener, optimized Structure Design, for production provide simply, reliable, practical, fast, technological equipment efficiently, its objective is the raising effect, the operating process of simplifying working process alleviates staff labor intensity.
For addressing the above problem, the utility model adopts following technical scheme: spacing oar loam core device for positioning and securing, comprise rising head case 7 and loam core arbor 5, and loam core arbor 5 vertically is provided with, and arbor 5 lower ends in loam core are fixedly connected on center above the rising head case 7; Also comprise rising head case foundary weight 1, loam core fixedly foundary weight 2 and loam core positioning sleeve 3; Two rising head case foundary weight 1 are parallel to each other and are horizontally placed on the both sides of loam core arbor 5; The horizontally disposed loam core fixedly centre of foundary weight 2 is welded with a vertical loam core positioning sleeve 3 that is provided with; Loam core fixedly foundary weight 2 is vertical with rising head case foundary weight 1, and loam core fixedly foundary weight 2 is pressed in above two rising head case foundary weight 1, and loam core positioning sleeve 3 is set on the loam core arbor 5; Rising head case foundary weight 1 fixedly is connected through locking constituent element 6 between the foundary weight 2 with the loam core; Positioning sleeve 3 sides are equipped with adjustment screw 4 in the loam core.
It is basic impetus that the fixture of the utility model is utilized FPP screw die mould decorative cover; With two rising head case foundary weight-arbor-loam cores, loam core fixedly foundary weight-devices such as loam core trimming bolt be coupled to each other; All adopt profiled member and standard component; Improve the utilization rate of material, improved operating efficiency simultaneously.
