Abstract
The utility model relates to a hot core box of an inner runner core of a reversing valve. The main body of the hot core box is a mold cavity which comprises two half hot core box cavities; the mold cavity comprises a main valve core hole, a main oil inlet arranged above the main valve core hole and communicated with the main valve core hole and left and right oil inlets at both sides of the main oil inlet. The innovation points of the hot core box lie in that the outer sides of the left and right oil inlets are respectively provided with an overload runner, and insert blocks being similar to the overload runners are jogged in the overload runners. The utility model has the advantages that the mold cavity of the hot core box, which is jogged with the insert blocks, can be used as the mold cavity for manufacturing the inner runner core of a non-load bearing reversing valve, whereas when the inner runner core of a load-bearing reversing valve needs to be manufactured, the insert blocks of the mold cavity in the hot core box are taken out. Two hot core boxes do not need to be manufactured independently, and thereby, the manufacture materials of human resource boxes are saved, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of reversal valve inner flow passage core hot box, the die cavity of main body for constituting by two halves sheet hot box, described die cavity comprises the main valve plug hole, the main oil-in that is located at top, main valve plug hole and is communicated with it, and the left and right oil-in of main oil-in both sides.
Background technology
Hot box is a technological equipment of core sand being made core, and it is made up of two halves sheet hot box usually, and the inner chamber of two halves sheet hot box constitutes core moulding die cavity.When making non-bearing formula reversal valve inner flow passage core, the die cavity of its hot box comprises the main valve plug hole, establishes the main oil-in of its top, and left and right oil-in.And making when manying bearing-type reversal valve inner flow passage core to the overload runner than non-bearing formula reversal valve inner flow passage core, normally make a hot box again and make.Cause the waste of various resources such as personnel, material, increased manufacturing cost.
The utility model content
The technical problems to be solved in the utility model provides a kind of hot box that not only can make bearing-type but also can make non-bearing formula reversal valve inner flow passage core.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of reversal valve inner flow passage core hot box, the die cavity of main body for constituting by two halves sheet hot box cavity, described die cavity comprises the main valve plug hole, the main oil-in that is located at top, main valve plug hole and is communicated with it, and the left and right oil-in of main oil-in both sides, its innovative point is: the described left and right oil-in outside is respectively equipped with the overload runner, and chimericly in the described overload runner has and the inserting of its profiling.
Advantage of the present utility model is: chimeric have the hot box die cavity inserted can be as the die cavity of making non-bearing formula reversal valve inner flow passage core, and when needing to make bearing-type reversal valve inner flow passage core, inserting of the inner die cavity of hot box taken out get final product.Need not make two hot boxs separately, save the human resources box and made material, reduce production cost.
Description of drawings
Accompanying drawing is the structural representation of the utility model reversal valve inner flow passage hot box.
The specific embodiment
As shown in drawings, the utility model relates to a kind of hot box of making reversal valve inner flow passage core, the die cavity of main body for being made of the inboard cavity of two halves sheet hot box, this die cavity is by main valve plug hole 1, main oil-in 2, left oil inleting port 3, right oil-in 4 and overload runner 5.
Above-mentioned main oil-in 2 is located at the top in main valve plug hole 1 and is communicated with it, the left and right oil-in 3,4 that is communicated with main valve plug hole 1 equally is set in the both sides of main oil-in 2, the overload runner was listed in the outside of left and right oil-in 3,4 in 5 minutes, was communicated with left oil inleting port 3, main valve plug hole 1 and right oil-in 4, main valve plug hole 1 respectively.In described overload runner 5, be inlaid with its profiling insert 6.
When making non-bearing formula reversal valve inner flow passage core, will insert 6 is connected and fixed by screw and hot box, is non-bearing formula reversal valve inner flow passage die cavity by the hot box die cavity of main valve plug hole 1, main oil-in 2, left oil inleting port 3,4 shapings of right oil-in; And when need making bearing-type reversal valve inner flow passage core, will insert and 6 take out, how to transship the die cavity of die cavity bearing-type in the red-letter day reversal valve inner flow passage that runner 5 forms by main valve plug hole 1, main oil-in 2, left oil inleting port 3, right oil-in 4.When adopting the hot box of this structure to make reversal valve inner flow passage core, only need to change slight 6 making that can finish bearing-type and non-bearing formula reversal valve inner flow passage core of inserting, need not prepare two independent hot boxs, saved resource and cost of manufacture.
Claims (1)
1. reversal valve inner flow passage core hot box, the die cavity of main body for constituting by two halves sheet hot box cavity, described die cavity comprises the main valve plug hole, the main oil-in that is located at top, main valve plug hole and is communicated with it, and the left and right oil-in of main oil-in both sides, it is characterized in that: the described left and right oil-in outside is respectively equipped with the overload runner, and chimericly in the described overload runner has and the inserting of its profiling.
