Abstract
The invention relates to the field of casting, and discloses a roller casting manufacturing method. The roller casting manufacturing method comprises: matching an upper box sand mold and a lower box sand mold, placing vertically, taking 5-7 sand molds in serial connection as an integral mold, arranging only one sprue gate on the integral mold, arranging zero riser, putting a cold iron column with the diameter of 25 mm at the center of the sand mold, and then performing vertical casting. Therefore, the interior of a produced roller does not form shrinkage cavities and shrinkage porosities, a compact casting is facilitated to be obtained, the internal quality is guaranteed, design requirements are realized, the yield is improved, and the casting cost is reduced.
Description
Technical field
The present invention relates to casting field, be specifically related to cast preparation method.
Background technology
Traditional pouring technology is made up of sprue, cross gate, ingate, riser runner and feeding head, and the effect of sprue is that molten metal is introduced cross gate and ingate, carries out filling die cavity through ingate; The Main Function of cross gate is that molten metal is steadily entered ingate with even and enough amount, and plays the effect of pushing off the slag, the air scavenge produced in die cavity when the effect of riser runner mainly will be poured into a mould, and prevents foundry goods from producing pore; The Main Function of feeding head is in the forming process of foundry goods, provide the molten metal needing due to Volume Changes to compensate, to prevent from occurring in foundry goods shrinking class defect.In process of production, adopt traditional explained hereafter method, the utilization rate of molten steel is 70%, and product yield ratio only has 69.36%, like this, not only waste raw material, reduce production efficiency, also add the operating time that workman cuts rising head, waste manpower and materials, improve casting cost.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of roller casting preparation method, adopt upright casting note, rising head casting preparation method is not set, improves the utilization rate of molten steel, reduce production cost, improve yield rate.
The object of the invention is to be achieved through the following technical solutions:
Produce top box sand mold and nowel sand mold;
Top box sand mold and nowel sand mold are got togather, stands up, series connection 5-7 part is as an integer;
Integer only arranges a sprue gate, does not arrange rising head, only places the chill that diameter is 25mm in sand mold center, then carries out upright casting note.
Advantageous Effects of the present invention: owing to have employed technique scheme, product yield is increased to more than 80% by 69.36%, and cast-internal does not have shrinkage cavity and porosity, improves casting quality, reduces casting cost, improves profit margin.
Accompanying drawing explanation
Fig. 1 is a top box sand mold schematic diagram.
Fig. 2 is a nowel sand mold schematic diagram.
Fig. 3 is an integer schematic diagram.
Wherein: 1, main running channel, 2, the frame of top box sand mold projection, 3, cross gate, 4, sand mold center, 5, sand mold mould, 6, sprue gate, the frame that 7 nowel sand molds are recessed.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of roller casting preparation method, comprise and produce top box sand mold and nowel sand mold, top box sand mold and nowel sand mold are got togather, stands up, connect 7 as an integer, integer only arranges a sprue gate 6, does not arrange rising head, only places in sand mold center 4 chill that diameter is 25mm, the roller inside of producing can not form shrinkage cavity and porosity, is conducive to obtaining closely knit foundry goods.Metal liquid is directly entered by sprue gate 6, molten metal is directly steadily entered cross gate 3 with even and enough amount by main running channel 1 by the molten metal after entering, heap sand mould die cavity 5 is entered through cross gate 3, while improve molten steel Utilization rate, product yield brings up to more than 80% by 69.36%, cast-internal does not have shrinkage cavity and porosity, reduces casting cost, improves profit margin.
Claims (2)
1. a roller casting preparation method, is characterized in that: top box sand mold and nowel sand mold are got togather, stands up, series connection 5-7 part is as an integer, and integer arranges a sprue gate, does not arrange rising head, only place a chill in sand mold center, then carry out upright casting note.
2. a kind of roller casting preparation method according to claim 1, is characterized in that: the diameter of described chill is 25mm.
