Description

Machine molding stripping pattern plate mounting structure

Technical field

The utility model relates to a kind of stripping pattern plate, relates in particular to a kind of stripping pattern plate mounting structure that is applied on the machine molding.

Background technology

Machine molding by placing sandbox, back-up sand, tight sand, molding, repairing work step such as type and forms, is all to finish or finish at least the formative method that tight sand is operated with machine mainly, its essence is with machine to replace manual tight sand and molding; It is different with the molding mode to press tight sand, and the machine molding method and the corresponding moulding machine of number of different types arranged.

At present, traditional machine modeling tool improves with the degree of packing, and the probability of bad type of molding increases, and usually pattern draft is done greatly for solving this contradiction, thereby is caused casting dimension accuracy poor, the molding complex structure.

The utility model content

For overcoming the deficiency on the prior art, the purpose of this utility model is to provide a kind of molding simple in structure, the machine molding that the cavity dimension precision is high stripping pattern plate mounting structure, guaranteed the shape and size precision at the position of complex outline and molding difficulty, even and the very high molding of the sand compaction sand that also can not collapse.

In order to realize the purpose of this utility model, the technical solution of the utility model is as follows:

Machine molding stripping pattern plate mounting structure, comprise that machine modeling plate and the machine that is arranged on the machine modeling plate make sandbox and moulding machine push rod, it is characterized in that, on described machine modeling plate, stripping pattern plate is installed and the machine that is arranged on is made model in the sandbox, also be provided with the model backing plate between described machine modeling plate and model, described model backing plate and model are fixedly connected, and promptly are linked and packed in one, described stripping pattern plate constitutes a template by assembling mutually with backing plate, and is arranged on the machine modeling plate.

According to above-mentioned machine molding stripping pattern plate mounting structure, wherein, described stripping pattern plate is arranged on machine and makes between sandbox and the machine modeling plate, and described machine modeling plate is fixed on the moulding machine workbench, and machine is made sandbox and is placed on above the stripping pattern plate by template alignment pin location.

Described stripping pattern plate is by joining with the backing plate cover, again with machine modeling plate overlaid, but not fixedly connected.

Behind the machine molding consolidation during molding, jemmy withstands that sandbox on stripping pattern plate and the stripping pattern plate is motionless, under the cylinder piston below the moulding machine workbench general who has surrendered's model from sand mold and stripping pattern plate down " leakage " go out to realize harmless molding.

The utility model is by technique scheme, and its molding is simple in structure, and cavity dimension precision height can guarantee the shape and size precision at the position of complex outline and molding difficulty, even and the very high molding of the sand compaction sand that also can not collapse.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Referring to Fig. 1 and Fig. 2, present embodiment machine molding stripping pattern plate mounting structure comprises that machine modeling plate 2 and the machine that is installed on the machine modeling plate 2 make sandbox 6 and moulding machine push rod 1; In making sandbox 6, machine is provided with model 5, this model 5 is arranged on the machine modeling plate 2 by model backing plate 4, stripping pattern plate 3 also is installed on machine modeling plate 2, this model backing plate 4 is assemblied in the middle part of stripping pattern plate 3, model backing plate 4 is arranged between machine modeling plate 2 and the model 5, stripping pattern plate 3 by with model backing plate 4 assembling again with machine modeling plate 2 overlaids, but do not connect.

In the present embodiment, carry out the line cutting at the appearance profile of cast iron plate upper edge model, dead head, form stripping pattern plate 3, the part of cutting off is placed between machine modeling plate 2 and the model 5 and makees model backing plate 4.Therefore, model backing plate 4 assembles mutually with machine mold board 2, constitute a template, stripping pattern plate 3 overlaps to join with model backing plate 4 is located and is placed on the machine modeling plate 2, this stripping pattern plate 3 is made between sandbox 6 and the machine modeling plate 2 at machine, this machine modeling plate is fixed on the moulding machine workbench, and machine is made sandbox 6 and is placed on above the stripping pattern plate by template alignment pin 7 location.

On four angles of machine modeling plate 2 lower surfaces, 4 moulding machine push rods 1 are installed respectively, behind the machine molding consolidation during molding, be arranged in that 4 moulding machine push rods 1 of four jiaos withstand that machine on stripping pattern plate 3 and the stripping pattern plate 3 makes that sandbox is 6 motionless, under the cylinder piston general who has surrendered's model 5 slaves make the sand mold of sandbox 6 and stripping pattern plate 3 down " leakage " go out to realize harmless molding.

Based on above-mentioned; bad type of molding when the utility model has solved traditional machine modeling tool well higher or pattern draft is very little in the degree of packing by installing stripping pattern plate 3 additional; and for preventing that bad type of molding from doing pattern draft the problem that causes the casting dimension accuracy difference greatly; the utility model molding is simple in structure; cavity dimension precision height can guarantee the shape and size precision at the position of complex outline and molding difficulty.Traditional casting mould is designed to solve this contradiction and usually pattern draft is done and caused casting dimension accuracy poor greatly, has solved this problem well after installing stripping pattern plate additional.

As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
