Abstract
The utility model relates to mould steel core and reduces the structure of steel pole of resistance of loosing core, and it comprises steel core body, and steel core body wears mold, and mold is extended in one end of steel core body; Described steel core body is divided into the first steel core body bonded to each other and the second steel core body by a point tangent plane, one end that the first steel core body and the second steel core body extend mold is respectively equipped with locating piece, and described first locating piece of steel core body and the distance of mold are less than second locating piece of steel core body and the distance of mold.Adopt above structure, steel core body is divided into the first steel core body and the second steel core body, by priority withdrawing the first steel core body and the second steel core body, greatly reduce the resistance of loosing core, improved the quality of foundry goods, and improved production efficiency.The utility model can be widely used in the occasion that various needs are loosed core.
Description
Technical field
The utility model relates to mould steel core and reduces the structure of steel pole of resistance of loosing core.
Background technology
Existing metal casting is in casting, because there are indent, side channel, side opening, screwed hole etc. in the inside of some metal casting, mould steel core need be set and after metal casting moulding, steel core need be extracted out, existing structure of steel pole resistance in the process of loosing core is large, production efficiency is low, and in the process of loosing core, easily causes the damage of metal casting, has virtually increased manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide the structure of steel pole that production efficiency is high, resistance is loosed core in the mould steel core reduction easily of loosing core.
For achieving the above object, the utility model is by the following technical solutions:
Mould steel core reduces the structure of steel pole of the resistance of loosing core, and it comprises steel core body, and steel core body wears mold, and mold is extended in one end of steel core body; Described steel core body is divided into the first steel core body bonded to each other and the second steel core body by a point tangent plane, one end that the first steel core body and the second steel core body extend mold is respectively equipped with locating piece, and described first locating piece of steel core body and the distance of mold are less than second locating piece of steel core body and the distance of mold.
Adopt above structure, the one end of extending mold due to the first steel core body and the second steel core body is respectively equipped with locating piece, described first locating piece of steel core body and the distance of mold are less than second locating piece of steel core body and the distance of mold, when the first steel core body and the second steel core body move with foundry goods, the locating piece of the locating piece of the first steel core body and the second steel core can successively touch mold, thereby the first steel core body and the second steel core sequencing are drawn out of, therefore greatly reduce the resistance of loosing core.
Bonded to each other of described the first steel core body and the second steel core body is inclined-plane, and the first steel core body is greater than the width of the second steel core body near mold one end near the width of mold one end.Because binding face is inclined-plane, in the process of first being loosed core at the first steel core, the first steel core cognition produces and separates with the second steel core body, and then has reduced the resistance of loosing core.
Described steel core body is cylinder.
The utility model adopts above technical scheme, and steel core body is divided into the first steel core body and the second steel core body, by priority withdrawing the first steel core body and the second steel core body, greatly reduces the resistance of loosing core, and has improved the quality of foundry goods, and has improved production efficiency.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
Fig. 1 is floor map of the present utility model.
Detailed description of the invention
As shown in Figure 1, mould steel core reduces the structure of steel pole of the resistance of loosing core, and it comprises steel core body 1, and steel core body 1 wears mold 2, and mold 2 is extended in one end of steel core body 1; Described steel core body 1 is divided into the first steel core body 11 bonded to each other and the second steel core body 12 by a point tangent plane, one end that the first steel core body 11 and the second steel core body 12 extend mold 2 is respectively equipped with locating piece 13,14, and the locating piece 13 of described the first steel core body 11 is less than the locating piece 14 of the second steel core body 2 and the distance of mold 2 with the distance of mold 2.
Bonded to each other of described the first steel core body 11 and the second steel core body 12 is inclined-plane.Because binding face is inclined-plane, in the process of first being loosed core at the first steel core 1, the first steel core body 1 can produce and separate with the second steel core body 2, and then has reduced the resistance of loosing core.
Described steel core body 1 can be cylinder, can certainly the side's of being main body etc. other shapes.
Operation principle of the present utility model: because locating piece 13 and the distance of mold 2 of the first steel core body 11 are less than the locating piece 14 of the second steel core body 12 and the minimum range of mold 2, when the first steel core body 11 and the second steel core body 12 move with foundry goods, the locating piece 13 of the first steel core body 11 and the locating piece 14 of the second steel core 12 can successively touch mold 2, under the effect of mold 2, the first steel core body 11 and the second steel core 12 can be drawn out of by sequencing, therefore greatly reduce the resistance of loosing core.The utility model can be widely used in the occasion that various needs are loosed core.
