Abstract
The utility model discloses a sand mould structure, which includes a sand mould body, a sand pool and a casting cavity both arranged inside the sand mould body, as well as a flow passage for connecting the sand pool with the casting cavity. The sand mould structure is characterized in that a concave platform lower than the upper plane surface of the sand mould is arranged on the periphery of an opening of the sand pool; the concave platform surrounds the opening of the sand pool, and is circular, L-shaped or T-shaped; and the depth of the concave platform is 5 mm to 50 mm. The sand mould structure has the benefits that the arranged concave platform offers a collection space for redundant molten iron, so that the molten iron can not spill over the sand mould plane surface even though excessive molten iron is cast, and damage to a mould weight and a pouring jacket during the casting is avoided.
Description
Technical field
The utility model relates to casting sand type, relates in particular to a kind of sand mold structure.
Background technology
Present casting industry adopts pipelining mostly, and this streamline collection sand mold manufacturing and moulding by casting are one.Its horizontal parting moulding machine forms sand mold through penetrating operations such as sand, extruding, following core and mould assembling, and the sand mold that gets into streamline is with the metallic sheath case according to its outside of arts demand, is provided with foundary weight at the top of sand mold, and sand mold forms foundry goods after pouring into a mould through streamline.The characteristics of this sand mold are that water the pond except that leaving at the top; All the other are planes, since difficult in the cast link to the control ratio of cast flow, molten iron usually can occur and overflow the situation of watering the pond; Cause foundary weight to be scalded or damage through regular meeting; What is more, and molten iron can also see through the air discharge duct inflow casing of foundary weight, and then scalds the damage casing, causes greater loss.
The utility model content
The utility model damages foundary weight and casing easily to prior art in moulding by casting not enough, and a kind of novel sand mold structure is provided.This sand mold structure can effectively be avoided in the casting process damage to foundary weight and casing.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of sand mold structure; Comprise the sand mold body, be located at sand pond, the foundry goods cavity of sand mold body interior and connect said sand pond and the runner of foundry goods cavity; It is characterized in that the mouth periphery is provided with the concave station that is lower than plane on the said sand mold in the sand pond in said sand pond.
This concave station can be provided with the boss plate through the joint portion at the upper extrusion board of horizontal parting moulding machine and cup and realize, promptly at extrusion process the concave station of sand mold is formed naturally.
The beneficial effect of the utility model is: through at the Sha Chikou periphery concave station being set, can give unnecessary collection space of molten iron, also can not overflow outside the sand mold plane even pouring molten iron is excessive, avoid in the casting process damage to foundary weight and casing.
Further, said concave station shape is round, " L " type or the T-shape around said sand Chi Kou.
The shape of said concave station can be provided with according to the shape of arts demand and foundary weight flexibly.
Further, the degree of depth of said concave station is 5～50 millimeters.The degree of depth of said concave station also can be selected with cast workpiece volume according to watering fluence control levels of precision.
Description of drawings
Fig. 1 is the sand mold structural representation of prior art;
Fig. 2 is the structural profile sketch map of the utility model;
Fig. 3 is the top shape sketch map of the utility model sand mold.
At Fig. 1 in Fig. 3,1, the sand mold body, 2, Sha Chi, 3, the foundry goods cavity, 4, runner, 5, concave station, 6, excessive molten iron, 7, casing, 8, foundary weight, 9, Sha Chikou.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Shown in Fig. 1, be the sand mold structure chart of prior art, because excessive molten iron 6 can cause the damage of foundary weight 8 and casing 7.
As shown in Figure 2, comprise sand mold body 1, be located at sand mold body 1 inner sand pond 2, foundry goods cavity 3 and connect the runner 4 of said sand pond 2 and foundry goods cavity 3, it is characterized in that 2 sand pond mouth 9 peripheries are provided with the concave station 5 that is lower than plane on the said sand mold in said sand pond.
As shown in Figure 3, said concave station 5 shapes are around said sand pond mouth 9 " L " type.It also can be round or T-shape.
The degree of depth of said concave station 5 is 5～50 millimeters.10 millimeters of preferred depth.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
