Description
Technical field
The utility model belongs to the technical field of metal casting technique equipment.More specifically, it the utility model is related to casting
The structure technology of moulding machine sandbox in equipment.
Background technology
At present, the horizontal removable-flask moulding technology in metal casting moulding machine, because its efficiency high, pollution Shaozheng are progressively obtaining
Popularization and application.It is but poor for the larger modeling effect of model difference in height by structural principle is limited.
Current horizontal boxless moulding machine structure and profile is substantially similar, as shown in Figure 1.Present horizontal boxless moulding machine institute
The moulding plate used is generally planar shaped, as shown in Figure 2.
When sand mold compresses, general compression ratio will could be compacted to 30% or so, but when the difference in height of model is larger, be put down
After the moulding plate of face shape compresses certain stroke, the sand mold compression ratio of deep recess point can be more much lower than projection, so as to cause
Molding quality is poor, or even failure.
Utility model content
The utility model provides horizontal boxless moulding machine pin profiling sand box board, and the purpose is to ensure the sand mold of compression forming
Quality.
To achieve these goals, the technical scheme that the utility model is taken is：
Horizontal boxless moulding machine pin profiling sand box board of the present utility model, described horizontal boxless moulding machine include upper sand
Bottom plate, cope frame, drag box bottom plate, drag box frame and mould；
Specifically there are following three kinds of technical schemes：
1st, described horizontal boxless moulding machine is provided with pin installing plate, described pin installing plate and described cope bottom
Plate connects；
2nd, described horizontal boxless moulding machine is provided with pin installing plate, described pin installing plate and described drag box bottom
Plate connects；
3rd, described horizontal boxless moulding machine is provided with two pin installing plates, respectively with cope bottom plate and drag box bottom plate
Connection.
Described pin installing plate is provided with multiple pin mounting holes and installs hole number identical pin with pin；It is described
Pin be arranged on pin mounting hole in；Described length of pin determines by mold profile, the end of described pin formed with
The similar profiling reverse of mold profile.
The utility model uses above-mentioned technical proposal, and pin different in size can be according to the profile of different models, flexibly
Combination, form the profiling reverse of corresponding pin composition.After sandbox is full of molding sand, when moulding plate compresses, each portion in sandbox
The sand mold compression ratio divided is more uniform, so that the sand-mould quality of extrusion forming is guaranteed.

Tool, 7, pin installing plate, 8, pin.
Embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further detailed
Thin explanation, with help those skilled in the art have to inventive concept of the present utility model, technical scheme it is more complete, accurate and
Deep understanding.
As shown in Fig. 2 cope bottom plate 2, cope frame are installed on the horizontal boxless moulding machine 1 used in the prior art
3rd, drag box bottom plate 4, drag box frame 5, mould 6.
The working method of prior art is:
During work, cope frame 3 and drag box frame 5 clip mould 6, distinguish shape with cope bottom plate 2 and drag box bottom plate 4
Into upper drag box cavity, after full of molding sand, the compressibility of horizontal boxless moulding machine assembly 1 can make cope bottom plate 2 with
The compression (or unilateral compression, mould 6 servo-actuated) in opposite directions of moulding plate 4, makes molding sand compression forming so as to reach, afterwards by the demoulding,
The processes such as matched moulds, complete moulding work.
Structure of the present utility model as expressed by Fig. 3, Fig. 4 and Fig. 5, it is horizontal boxless moulding machine pin profiling sandbox
Plate, described horizontal boxless moulding machine 1 include cope bottom plate 2, cope frame 3, drag box bottom plate 4, drag box frame 5 and mould
6。
The defects of in order to overcome prior art, the goal of the invention for the sand-mould quality for ensureing compression forming is realized, this practicality is newly
The technical scheme that type is taken is：
As shown in figure 5, horizontal boxless moulding machine pin profiling sand box board of the present utility model, specifically there is following three kinds of sides
Case：
1st, described horizontal boxless moulding machine is provided with pin installing plate 7, described pin installing plate 7 and described cope
Bottom plate 2 connects；
2nd, described horizontal boxless moulding machine is provided with pin installing plate 7, described pin installing plate 7 and described drag box
Bottom plate 4 connects；
3rd, described horizontal boxless moulding machine is provided with two pin installing plates 7, respectively with cope bottom plate 2 and drag box bottom
Plate 4 connects.
The utility model is specially designed by the base arrangement to moulding machine sandbox, and one is connected on the bottom plate of sandbox
It is individual to be used to the bottom plate of pin be installed, there are some pin mounting holes on bottom plate, according to the profile of model, length is installed on bottom plate in advance
