Abstract
The utility model relates to a kind of casting mold rising head.In traditional foundry production, many foundry enterprises still use common riser feeding, and the yield rate of product only has about 51%, and product shrinkage porosite, and shrinkage cavity defect is also general, makes casting qualified rate about 85%.The utility model is characterized in that comprising rising head body, and bottom and the casting of rising head body are touched die cavity and be communicated with, the upper taper passage of described rising head main body, and the expansion slot of step is formed at the bottom of rising head main body, and the outer setting insulation of described rising head main body is outer.The utility model adopts the exothermic riser improved, and casting quality totally obviously rises, and uses exothermic riser feeding, and foundry goods yield rate reaches 74-78%.Shrinkage porosite, the shrinkage cavity phenomenon of foundry goods are almost nil.
Description
Technical field
The utility model relates to a kind of foundry industry technique, especially a kind of casting mold rising head.
Background technology
In traditional foundry production, many foundry enterprises still use common riser feeding, and the yield rate of product only has about 51%, and product shrinkage porosite, and shrinkage cavity defect is also general, makes casting qualified rate about 85%.Adopt common rising head to add and easily form foundry goods burning into sand man-hour, usually need manual operation to remove, waste time and energy, affect product quality.
Utility model content
The utility model, for the problems referred to above, provides a kind of casting mold rising head, improves casting yield and qualification rate, reduces energy resource consumption.
For this reason, the utility model takes following technical scheme, a kind of casting mold rising head, it is characterized in that comprising rising head body, bottom and the casting of rising head body are touched die cavity and are communicated with, the upper taper passage of described rising head main body, the expansion slot of step is formed at the bottom of rising head main body, and the outer setting insulation of described rising head main body is outer.
The middle part of described rising head main body forms the Vertical Channel connecting expansion slot and tapered channel.
Described rising head body has cavity, in cavity, fills exothermic mixture.
Described insulation skin is fiber composite type or expanded pearlite lithotype muff.
Described exothermic mixture is iron oxide and aluminium bits.
The utility model adopts the exothermic riser improved, and casting quality totally obviously rises, and uses exothermic riser feeding, and foundry goods yield rate reaches 74-78%.Shrinkage porosite, the shrinkage cavity phenomenon of foundry goods are almost nil.Casting qualified rate reaches 98%, and production cost decline 11-15%, has saved energy resource consumption greatly, improve productivity ratio, ensure that the delivery cycle.The channels designs of rising head main body can effectively avoid coating in the problem being piled into overlap at this place, saves the work of blade coating impurity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is application structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.
As depicted in figs. 1 and 2, a kind of casting mold rising head, comprises rising head body 3, bottom and the casting of rising head body 3 are touched die cavity and are communicated with, the upper taper passage 1 of rising head main body 3, the expansion slot 5 of step is formed at the bottom of rising head main body 3, the outer setting insulation outer 4 of rising head main body 3.The middle part of rising head main body 3 forms the Vertical Channel 2 connecting expansion slot 5 and tapered channel 1.Rising head body has cavity, in cavity, fills exothermic mixture.Insulation skin is fiber composite type or expanded pearlite lithotype muff, and exothermic mixture is iron oxide and aluminium bits.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
