Embodiment

[0037] 1. According to the combined casting (such as figure 1 Shown) size to select the appropriate guard plate (such as figure 2 Shown) size, for example, in the embodiment, it is 1000 long, 200 high, and 15 thick. Reinforced flanging can be set around the guard plate, and reinforcing ribs can be set inside the guard plate. guard plate ( figure 2 ) The top, bottom and back are machined surfaces. Set a reinforced thick platform on the guard plate, the reinforced thick platform is 20mm away from the horizontal center line of the guard plate, and 4 oblong holes are arranged at both ends of the reinforced thick platform. The length and spacing of the oblong holes should ensure that the combined size of the left and right oblong holes is continuous. For example, in the embodiment, the distance between the centers of the oblong holes is 35mm, the distance between the connected oblong holes is 10mm, and the distance between the most two oblong holes and the side of the guard pl...

Abstract

A protective device and method for resin-sand composite molds, the device includes guard plates, fastening rods, mold fastening holes, gaskets, and fastening bolts; multiple guard plates are placed in parallel around the resin sand core, and each guard plate There is an oblong hole on the top, and the oblong hole is used to cooperate with the fastening hole reserved on the resin sand core. The fastening rod passes through the oblong hole and the fastening hole, and is fastened with gaskets and nuts on both sides. . The resin-sand combined mold protection device and method thereof proposed by the present invention can provide a uniform fastening force for the resin-sand combined mold, and at the same time provide protection similar to a sand box during the pouring process, which can realize the protection of the protection device. Standardized serial preparation, easy to use.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a resin sand mold protection device and its application method. Difficulty in mold shakeout cleaning. Background technique [0002] With the application of resin self-setting sand in the process of molding and core making, the technology of resin-sand combined molding has gradually matured, and it also provides the possibility for boxless molding. The existing boxless molding is generally applied to small parts, but in the field of large-scale castings, especially in the field of low-pressure casting of large-scale castings, how to ensure that the mold combination is in place and prevent quality problems such as run-off during the pouring process requires further process optimization and exploration. . Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, and to propose a protection dev...
