Description
Art
The utility model relates to field of metal casting technology, especially relates to 465 Q motor cylinder block sand core of water jacket adhesive positioning device in casting process.
Background technology
Sand core of water jacket is typically made as raw material with phenolic resin and precoated sand, the cylinder cover of automobile engine needs to add sand core of water jacket in metal die for constituting die cavity in casting process, being removed by core viberating knock-out machie after shaping, the position originally putting core is the formation of the cooling water channel of engine.
Present stage, the mode that bonding sand core of water jacket uses in 465Q rough-cast operation is to be combined scattered for two panels core by hand.Only simply being positioned with groove fit by two director's strip bulges time bonding, short transverse size can not position.Because sand core of water jacket die joint quality of fit requires higher, manual operations was the most at that time, it is easy to causing the situation producing bonding dislocation in short transverse, add horizontal direction and position also inaccuracy, product is up to about 20% because of off-dimension scrappage.
Summary of the invention
In order to solve, the cylinder holes that the above-mentioned 465Q bonding dislocation of motor cylinder block sand core of water jacket causes is inclined, wall thin equidimension problem, the utility model provides 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described adhesive positioning device includes some bases and cylindrical body, being provided with cylindrical body on described each base, the cylinder less with cylindrical body concentric diameter is arranged at described each cylindrical body top.
Further, in 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described diameter is identical with sand core of water jacket semicircle internal diameter compared with small column radius.The mode of original manual simple positioning bonding is improved by the utility model, increases cylinder-shaped top relatively small column radius and positions corresponding portion with sand core of water jacket.
Further, in 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described cylindrical body spacing is identical with water jacket sand mold semicircle spacing.Former manual location only positions protruding for two ends, 465Q motor cylinder block sand core of water jacket left and right correspondence strip with groove fit, it is easy to cause the situation producing bonding dislocation in short transverse.The utility model increases cylindrical shoulder further and positions corresponding portion with 465Q motor cylinder block sand core of water jacket.
Further, in 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described base the cylindrical body at least two corresponding with base.
Further, in 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described adhesive positioning device material is sand, cast iron.
The utility model increases sand core of water jacket arc surface, two cemented in place of step, and anchor point is increased to three by original sand core of water jacket both sides square hole coarse positioning, it is ensured that the bonding height of sand core of water jacket, width do not have misalignment.Using the utility model, 465Q motor cylinder block sand core of water jacket is after bonding, and the situation of sand core of water jacket dislocation is reduced to less than 3% by original 20%, and the 465Q motor cylinder block blank scrappage caused because of the bonding dislocation of sand core of water jacket is reduced to 0.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model being described in detail, so that skilled artisan understands that advantage of the present utility model and feature, thus protection domain of the present utility model being made apparent clear and definite defining.
In the prior art, Fig. 1 a, 1b are core front view, top view on the left of 465Q motor cylinder block water jacket, and in figure, 1,2 are respectively square hole location (convex surface) in prior art.Fig. 2 a, 2b are core front view, top view on the right side of 465Q motor cylinder block water jacket in prior art, and in figure, 1 ', 2 ' is square hole location (concave surface).Fig. 3 a, 3b are 465Q motor cylinder block sand core of water jacket bonding assembling front view, top view in prior art, and in figure, convex surface socket joint positions in concave surface.Present stage, the mode that bonding sand core of water jacket uses in 465Q rough-cast operation is to be combined scattered for two panels core by hand.Only simply being positioned with groove fit by two director's strip bulges time bonding, short transverse size can not position.Because sand core of water jacket die joint quality of fit requires higher, manual operations was the most at that time, it is easy to causing the situation producing bonding dislocation in short transverse, add horizontal direction and position also inaccuracy, product rejection rate is higher.
In order to solve, the cylinder holes that the above-mentioned 465Q bonding dislocation of motor cylinder block sand core of water jacket causes is inclined, wall thin equidimension problem, the utility model provides 465 Q motor cylinder block sand core of water jacket adhesive positioning devices, described adhesive positioning device 5 includes some bases and cylindrical body, it is provided with cylindrical body on described each base, the cylinder less with cylindrical body concentric diameter is arranged at described each cylindrical body top, diameter is identical with sand core of water jacket semicircle internal diameter compared with small column radius, and cylindrical body spacing is identical with water jacket sand mold semicircle spacing.
