Plate spring base support pouring mold and pouring method

Abstract

The invention discloses a plate spring base support pouring mold and a pouring method. The plate spring base support pouring mold comprises an upper sand mold, pouring hoppers, a lower sand mold, support assemblies and pieces of lost foam. An upper sand mold frame sleeves the upper sand mold, and a lower sand mold frame sleeves the lower sand mold. Mold cavities are evenly formed in the face, matched with the upper sand mold, of the lower sand mold, and the pieces of lost foam are placed in the mold cavities. A pouring channel is further formed in the middle of the face, matched with the uppersand mold, of the lower sand mold, and is a nonlinear straight channel. According to the plate spring base support pouring mold and the pouring method, the flow velocity of the poured liquid is moderate, bubbles are timely discharged, finished products are complete, and the yield is high. The pouring technology is simple, the operation is easy, carbon dioxide is used for conducting curing operation, and the curing effect is good. In addition, the multiple products can be formed by the one-time pouring operation, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing a leaf spring seat bracket, in particular to a casting mold and a casting method for a leaf spring seat bracket. Background technique [0002] Most of the leaf spring seat brackets have two protruding tips. When making the leaf spring seat bracket, the method of sand mold casting is adopted. By pouring the pouring liquid into the mandrel, and then waiting for it to cool, the leaf spring seat support can be obtained . [0003] However, in the sand casting process, in the narrow tip of the width, the pouring speed of molten iron is too fast, the gas is not discharged in time, and bubbles are easily generated, resulting in a decline in product quality. A split bottom pouring model for ductile iron gray iron casting. Specifically, the measures of setting buffer plates, buffer channels and combining diversions are used to reduce the speed of molten iron pouring. However, in the casting process o...

[0003] However, in the sand casting process, in the narrow tip of the width, the pouring speed of molten iron is too fast, the gas is not discharged in time, and bubbles are easily generated, resulting in a decline in product quality. A split bottom pouring model for ductile iron gray iron casting. Specifically, the measures of setting buffer plates, buffer channels and combining diversions are used to reduce the speed of molten iron pouring. However, in the casting process of sand molds, the setting of buffer plates It is extremely difficult. In the process of making the core mold, it is difficult to place the buffer sheet into the sprue in the core mold. Therefore, it is necessary to provide a casting mold for the leaf spring seat bracket with a simple structure and easy to make.
