Description
Technical field
The present invention relates to the cover half of a kind of crankcase water channel core and manufacture water channel core, particularly relating to a kind of by increasing the crankcase high strength water channel core and high strength water channel core cover half of strengthening gripper shoe raising intensity.
Background technology
In the foundry production of automobile engine, for the cast model of crankcase, usually all include main core, water channel core, oil duct core, outside core and end face core.At present, in the engine crankshaft box foundry goods that company produces, have a kind of water channel shape of crankcase to be Zhuan Bao chamber, annulus, thus, when designing the casting sand core of this crankcase, the water channel core of formation water channel is corresponding is also annular thin-walled core.The water channel cored structure of this thin-walled in coremaking, park, carry, in mould assembly and casting process, easily deform or rupture, therefore foundry goods is also scrapped or clears up inner chamber sand grains difficulty, has both reduced the qualification rate of foundry goods, and has turn increased cost.In order to prevent distortion or the fracture of water channel core, stud (a kind of metal support for supporting core in casting mold) just must be adopted to fix water channel core, but the stud structure of routine can not be useful on water channel core.
Summary of the invention
Object of the present invention is just to provide a kind of crankcase high strength water channel core and high strength water channel core cover half to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
Crankcase high strength water channel core of the present invention comprises the hollow cylindrical unit of multiple vertical direction be connected in parallel to each other, be provided with the reinforcement gripper shoe being parallel to vertical direction between adjacent two described hollow cylindrical unit, two, the left and right side of described reinforcement gripper shoe is placed in the connector between two adjacent described hollow cylindrical unit.Above-mentioned reinforcement gripper shoe is identical with the effect of traditional stud, but structure is different, is only suitable as the stud of water channel core of the present invention.
In order to prevent the connector not enlargement and contraction between adjacent two hollow cylindrical unit further, two, the left and right side of described reinforcement gripper shoe is respectively equipped with spacer.
As preferably, two, the left and right side of described reinforcement gripper shoe is respectively equipped with two spacers, in 30 degree of angles between two described spacers of homonymy.
Further, described spacer is positioned at the middle part of two sides in left and right of described reinforcement gripper shoe; Described spacer is placed in the connector between two adjacent described hollow cylindrical unit.
Particularly, described hollow cylindrical unit is four, and described reinforcement gripper shoe is three.Four hollow cylindrical unit are conventional water channel cored structures.
Preferably, described reinforcement gripper shoe is rectangle steel plate, and the left and right marginal portion, downside of described reinforcement gripper shoe is provided with lower convex locating dowel; Described locating dowel is placed in the connector between two adjacent described hollow cylindrical unit.
Crankcase high strength water channel core cover half of the present invention comprises the cover half cylinder cup of the vertical direction of multiple connection arranged side by side, is provided with for installing the support slot being parallel to vertical direction strengthening gripper shoe between adjacent two described cover half cylinder cups.
Particularly, described cover half cylinder cup is four, and described support slot is three.
Beneficial effect of the present invention is:
The present invention strengthens gripper shoe by increasing between adjacent two hollow cylindrical unit, makes water channel core not easily deform or rupture, extends service life, and the water channel inner chamber also having stopped crankcase produces sand grains, guarantees the water channel size qualification of crankcase; Arrange two respectively at two, the left and right side strengthening gripper shoe be mutually the spacer of angle and spacer embedded in water channel core body, can prevent two double walls of water channel core from expanding outwardly and inwardly shrink; By arranging support slot between two adjacent cover half cylinder cups of water channel core cover half, only need reinforcement gripper shoe be placed in support slot when manufacturing water channel core, naturally be integrated with reinforcement gripper shoe after water channel core is shaping.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, crankcase high strength water channel core 2 of the present invention comprises the hollow cylindrical unit 8 of the vertical direction that four are connected in parallel to each other, the reinforcement gripper shoe 1 being parallel to vertical direction is provided with between two adjacent hollow cylindrical unit 8, two, the left and right side strengthening gripper shoe 1 is placed in the connector between two adjacent hollow cylindrical unit 8, strengthen gripper shoe 1 totally three, be rectangle steel plate, this steel plate adopts the Q235 steel plate that 1.5mm is thick, is shaped by stamping parts.
As shown in Figure 3, the middle part strengthening two sides in left and right of gripper shoe 1 is respectively provided with two spacers 4 respectively, in 30 degree of angles between two spacers 4 of homonymy; The breach that the left and right marginal portion, downside strengthening gripper shoe 1 is provided with between lower convex locating dowel 5, two locating dowels 5 is consistent with the base boss shape below the cover half cylinder cup 3 of the water channel core cover half in Fig. 2.As shown in figures 1 and 3, spacer 4 and locating dowel 5 are all placed in the connector between two adjacent hollow cylindrical unit 8.
As shown in Figure 2 and Figure 4, crankcase high strength water channel core cover half of the present invention comprises the cover half cylinder cup 3 of the vertical direction that four connect side by side, is provided with for installing the support slot 6 being parallel to vertical direction strengthening gripper shoe 1 between two adjacent cover half cylinder cups 3.Support slot 6 is three.
Composition graphs 1-Fig. 4, when manufacturing water channel core 2, strengthen gripper shoe 1 by three and be placed in three support slots 6 respectively, then water channel core mold matched moulds core shooting is shaping, is naturally integrated, by the water channel core 2 upwards demoulding after water channel core 2 is shaping with reinforcement gripper shoe 1.
As shown in Figure 5, conventional crankshafts casing water channel core 7 also comprises the hollow cylindrical unit 8 of the vertical direction that four are connected in parallel to each other, but middle part is empty between adjacent two hollow cylindrical unit 8, both sides are thin-walled, thus in coremaking, park, carry, easily deform in mould assembly and casting process or rupture.
As shown in Figure 6, conventional crankshafts casing water channel core cover half also comprises the cover half cylinder cup 3 of the vertical direction that four connect side by side, but does not arrange support slot between adjacent two cover half cylinder cups 3, and the water channel core of casting is exactly the conventional crankshafts casing water channel core 7 of Fig. 5.
