Abstract
The utility model discloses a high-strength water channel core of a crankcase body. The high-strength water channel core comprises a plurality of hollow cylindrical units in a vertical direction which are interconnected in parallel; a reinforcing support plate parallel to the vertical direction is arranged between two adjacent hollow cylindrical units; left and right sides of each reinforcing support plate are placed in a connection body between the two adjacent hollow cylindrical units. The utility model also discloses a high-strength water channel core fixed mold of the crankcase body. The high-strength water channel core fixed mold comprises a plurality of fixed mold cylinder cups in the vertical direction which are interconnected in parallel; a support tank parallel to the vertical direction for mounting the reinforcing support plate is arranged between two adjacent fixed mold cylinder cups. As the reinforcing support plate is additionally arranged between the two adjacent hollow cylindrical units, the water channel core is unlikely to deform or rupture, the service life is prolonged, sand grains generated by a water channel intracavity of the crankcase body are avoided, and the qualified water channel size of the crankcase body is guaranteed.
Description
Technical field
The utility model relates to a kind of crankcase water channel core and manufactures the cover half of water channel core, relates in particular to a kind ofly by increase, to strengthen gripper shoe and carry high-intensity crankcase high strength water channel core and high strength water channel core cover half.
Background technology
In the foundry production of automobile engine, for the cast model of crankcase, conventionally 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, the water channel shape that has a kind of crankcase is Zhuan Bao chamber, annulus, thereby when the casting sand core of this crankcase of design, 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, in carrying, mould assembly and casting process, easily deform or rupture, therefore foundry goods is also scrapped or clear up inner chamber sand grains difficult, has both reduced the qualification rate of foundry goods, has increased again cost.In order to prevent distortion or the fracture of water channel core, just must adopt stud (a kind of metal support that supports core for casting mold) to fix water channel core, but conventional stud structure can not be useful on water channel core.
Utility model content
The purpose of this utility model provides a kind of crankcase high strength water channel core and high strength water channel core cover half with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Crankcase high strength water channel core described in the utility model comprises the hollow cylindrical unit of a plurality of vertical directions that mutually connect side by side, between two adjacent described hollow cylindrical unit, be provided with the reinforcement gripper shoe that is parallel to vertical direction, two of 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 described in the utility model.
In order further to prevent not enlargement and contraction of connector between adjacent two hollow cylindrical unit, two of the left and right side of described reinforcement gripper shoe is respectively equipped with spacer.
As preferably, two of the left and right of described reinforcement gripper shoe side is respectively equipped with two spacers, between two described spacers of homonymy, is 30 degree angles.
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 of downside of described reinforcement gripper shoe is provided with lower protruding 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 described in the utility model comprises the cover half cylinder cup of the vertical direction of a plurality of connections arranged side by side, is provided with the support slot that is parallel to vertical direction of strengthening gripper shoe for installing between two adjacent described cover half cylinder cups.
Particularly, described cover half cylinder cup is four, and described support slot is three.
The beneficial effects of the utility model are:
The utility model is strengthened gripper shoe by increasing between adjacent two hollow cylindrical unit, make water channel core be difficult for deforming or rupturing, extended service life, the water channel inner chamber of also having stopped crankcase produces sand grains, guarantees that the water channel size of crankcase is qualified; At two of the left and right side of strengthening gripper shoe, arrange respectively two and be mutually the spacer of angle and spacer embedded in water channel core body, can prevent that two double walls of water channel core from expanding outwardly and inwardly shrinking; By between two adjacent cover half cylinder cups of water channel core cover half, support slot being set, while manufacturing water channel core, only need be placed in support slot strengthening gripper shoe, after the moulding of water channel core, be naturally integrated with reinforcement gripper shoe.
