Abstract
A kind of mold being used to form casting sand type pouring basin, in rectangular groove structure, it is fixedly mounted on the posture of opening upwards on the squeeze board of horizontal moulding machine, in a corner part of mold, the sprue gate of setting and gate stick cooperation, excess-three corner use arc surface transition structure.Using the mold described in the utility model for being used to form casting sand type pouring basin, after the completion of sand mold moulding, peviform molten iron cushion chamber is formed in the cast gate position of sand mold, so that pouring molten iron stream can initially enter cushion chamber in casting process, entered in sand mold die cavity by running channel again, pass through the pressure stabilization function of cushion chamber, the running channel position inaccurate for not only avoiding hot metal flow and sand mold and the overflow phenomena in the excessive situation of molten iron casting amount, and the sand washing defect occurred in casting process is eliminated, to achieve the purpose that improve cast article quality and working efficiency.
Description
Technical field
The utility model relates to a kind of molds for being used to form casting sand type pouring basin, belong to sand casting technical field.
Background technique
In sand casting process process, boxless moulding machine is the equipment for manufacturing sand mold, such as a kind of match plate
Drawing formula moulding machine, it using horizontal moulding, penetrate sand vertically downward plus sand model, pass through big dynamicliquid pressure squeeze, compacting, water
Modeling process is completed in the operations such as flat Xiang Qimo, horizontal direction mould assembly.Above-mentioned match plate drawing formula moulding machine and full-automobile casting machine
Link operation, is located above die cavity by the sand mold molten iron casting mouth that the match plate drawing formula moulding machine manufactures, due to its molten iron
Sprue gate is directly connect with running channel, there are problems that following both sides in casting process: first is that casting machine and moulding machine cooperate
Synchronism it is unstable, the running channel position inaccurate of hot metal flow and sand mold under the casting condition that links can not only outflow because of molten iron
Cause to shut down phenomenon, affect production efficiency, and be poured it is unstable will cause sand washing waste product, affect casting quality；Second is that
The water yield of casting machine is difficult to control, and molten iron casting amount difference is big, when being poured excessive molten iron, can be caused because molten iron is excessive
The damage of mo(u)lding line.
Utility model content
The utility model provides a kind of mold for being used to form casting sand type pouring basin, it is intended to be made by the buffering of pouring basin
With solving the problems, such as that molten iron present in casting process is excessive and sand washing, reach the mesh for improving cast article quality and working efficiency
's.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of mold being used to form casting sand type pouring basin is in rectangular groove structure, with the fixed peace of the posture of opening upwards
On the squeeze board of horizontal moulding machine, the sprue gate of setting and gate stick cooperation in a corner part of rectangular channel, remaining
Three corners use arc surface transition structure.
The above-mentioned mold for being used to form casting sand type pouring basin, bottom surface crossed by the first inclined surface and the second inclined surface and
At first inclined surface and the second inclined surface form raised intersection line, the intersection line at the diagonal line of mold bottom surface
One end is connect with sprue gate, and the other end is connected with corresponding corner arc face, and intersection line connection sprue gate one end is higher than connection
Corner arc face one end.
The above-mentioned mold for being used to form casting sand type pouring basin pulls out in the setting of its side wall and touches angle [alpha].
The above-mentioned mold for being used to form casting sand type pouring basin, using mould steel material.
The above-mentioned mold for being used to form casting sand type pouring basin, rectangular channel outer dimension are 265mmx205mmx30mm,
Circular arc radius surface R=45mm of three corners, the bottom surface inclined surface Liang Ge angle with horizontal plane β=3 °, side wall, which pulls out, touches angle [alpha]=10 °,
Side wall and bottom surface are with the arc transition of radius r=15mm.
The utility model is a kind of mold for being used to form casting sand type pouring basin, is mounted on the squeeze board of horizontal moulding machine
On, after the completion of moulding, peviform molten iron cushion chamber is formed at the cast gate position of sand mold, therefore in casting process, hot metal flow can be first
It is introduced into cushion chamber, then is entered in sand mold die cavity by running channel, by the pressure stabilization function of cushion chamber, not only avoids hot metal flow and sand
The running channel position inaccurate of type and the overflow phenomena in the excessive situation of molten iron casting amount, and eliminate and occur in casting process
Sand washing defect；Also design is optimized to mold bottom surface structure in the utility model, ensure that the molten iron cushion chamber bottom surface of sand mold
Sprue gate is in extreme lower position, and the molten iron being more advantageous into cushion chamber flows into sand mould chamber.In conclusion the utility model
It solves the problems, such as that molten iron present in casting process is excessive and sand washing, has reached the mesh for improving cast article quality and working efficiency
