Abstract
The utility model discloses a kind of arbor structure preventing engine cylinder-body water channel core to be out of shape.Comprise the arbor be arranged in engine cylinder-body water channel core, arbor comprises horizontally disposed horizontal arbor and vertically disposed vertical arbor, and horizontal arbor and vertical arbor connect and compose fence type structure; Horizontal arbor flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position; Vertical arbor Vertical Uniform interval in water channel core arranges and is connected and fixed with multiple-layer horizontal arbor.The utility model adopts fence type arbor, and horizontal arbor and vertical arbor " are closely connected " increases the rigidity of core, and its deflection is little; Horizontal arbor flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position, strengthen the strength and stiffness of water channel core entirety, decrease the distortion of water channel core, ensure that the wall thickness requirement of medial and lateral, cylinder block cooling water road.
Description
Technical field
The utility model belongs to metal casting technique field, especially belongs to motor cylinder block casting technology field, particularly a kind of arbor structure preventing engine cylinder-body water channel core to be out of shape in motor cylinder block casting.
Background technology
Automobile engine cylinder-body is first by casting machine-shaping, and need in cylinder casting to use water channel core to form the cooling water channel of casting rear-bank rotor housing, usual cooling water channel has the structure around cylinder block.
Because the water channel film covered sand core of engine cylinder-body water channel core usually only has a few millimeters thick, and precoated sand can deform under heat effect, arbor is set increases core rigidity so need to add water channel core and carry out Reducing distortion amount, existing arbor is the arbor adding single formula, namely in water channel core, increase respective independent arbor, and be mainly arranged on thicker position; In single formula arbor, arbor " is done things in his own way ", and its ability increasing core rigidity is less, therefore the reduction degree of its deflection can not be satisfied the demand, and particularly more can not meet intensity in the less position of water channel core thickness and reduce the needs be out of shape.
Summary of the invention
The utility model discloses a kind of arbor structure preventing engine cylinder-body water channel core to be out of shape according to the deficiencies in the prior art.Problem to be solved in the utility model be by change arbor structure is set, provide one to meet more high strength requirement, be out of shape less engine cylinder-body water channel core arbor structure.
The utility model is achieved through the following technical solutions:
Prevent the arbor structure that engine cylinder-body water channel core is out of shape, comprise the arbor be arranged in engine cylinder-body water channel core, it is characterized in that: described arbor comprises horizontally disposed horizontal arbor and vertically disposed vertical arbor, and horizontal arbor and vertical arbor connect and compose fence type structure.
Described horizontal arbor flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position.
Described vertical arbor Vertical Uniform interval in water channel core arranges and is connected and fixed with multiple-layer horizontal arbor.
The utility model helpfulness, the utility model adopts fence type arbor, and horizontal arbor " is closely connected " with vertical arbor, greatly increases the rigidity of core, and the reduction degree of its deflection is ideal; The utility model horizontal arbor flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position, this structural strengthening strength and stiffness of water channel core entirety, the distortion of water channel core is decreased when carrying out cylinder casting, ensure that the wall thickness requirement of medial and lateral, cylinder block cooling water road, improve end product quality.
Accompanying drawing explanation
Fig. 1 is the utility model water channel core plan structure perspective diagram;
Fig. 2 is the utility model water channel core Facad structure perspective diagram;
Fig. 3 is existing water channel cored structure perspective diagram.
In figure, 1 is water channel core, and 2 is arbors, and 21 is vertical arbors, and 22 is horizontal arbors, and 3,5 is water channel thickness, and 4 is existing water channel cores.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.Embodiment, for illustration of the utility model, limits the utility model never in any form.
Composition graphs 1 and Fig. 2.
Prevent the arbor structure that engine cylinder-body water channel core is out of shape, comprise the arbor 2 be arranged in engine cylinder-body water channel core 1, arbor 2 comprises horizontally disposed horizontal arbor 22 and vertically disposed vertical arbor 21, and horizontal arbor 22 connects and composes fence type structure with vertical arbor 21.
Horizontal arbor 22 flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position.
Vertical arbor 21 Vertical Uniform interval in water channel core arranges and is connected and fixed with multiple-layer horizontal arbor 22.
As shown in Figure 1 and Figure 2, in Fig. 1, water channel core 1 only has 3 millimeters, 5 millimeters thick respectively in water channel thickness 3,5 position and symmetric position thereof, is easy to distortion in casting.The utility model comprises horizontally disposed horizontal arbor 22 and vertically disposed vertical arbor 21, horizontal arbor 22 and vertical arbor 21 connect and compose fence type structure, and horizontal arbor 22 flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position.As being horizontally disposed with of representing of thick line in the horizontal arbor 22, Fig. 2 that represents around the thick line of water channel core in Fig. 1 and vertically disposed horizontal arbor 22 and vertical arbor 21.Horizontal arbor 22 and vertical arbor 21 " being closely connected ", greatly increase the rigidity of water channel core 1, horizontal arbor 22 flat shape is identical with engine cylinder-body cooling water channel flat shape and arrange around engine cylinder-body cooling water channel peripheral position, the bulk strength of this structural strengthening water channel core 1 and rigidity, the distortion of water channel core is decreased when carrying out cylinder casting, ensure that the wall thickness requirement of medial and lateral, cylinder block cooling water road, improve end product quality.
Fig. 3 is existing water channel cored structure perspective diagram, in figure, existing water channel core 4 is vertically arranged, and do not strengthen in the position around cylinder block passage core arranging, when cylinder body is shaping, usually there is very large deformation in its water channel core, cause the wall thickness of medial and lateral, cylinder block cooling water road not meet the demands, qualified casting is low.
