Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a crushing device for recovering sand molds. Background Art

[0002] Sand casting is a widely used form of casting. Sand casting requires placing a finished part model in the sand, filling the model with sand at the end of the pattern, and forming a mold after the model is taken out of the box. The mold is poured with liquid metal and kept for a suitable time until the metal solidifies. The finished parts are taken out by breaking the sand mold. Each casting needs to be remade into a new mold. Therefore, the breaking of the casting sand mold is one of the necessary tasks in the sand casting process. After the sand mold is finished casting the parts, the sand mold needs to be broken so that the sand grains of the sand mold can be recycled and reused.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese patent publication number: CN205869377U discloses a sand mold crushing and recovery device, including a workbench, a material barrel rotatably mounted on the workbench, and a motor, the material barrel is driven by the motor, the bottom of the material barrel is evenly distributed with sieve holes, an inclined material guide trough is fixed below the material barrel on the workbench, striking blocks are evenly distributed on the inner wall of the material barrel around the axis of the material barrel, a truncated cone is fixed in the material barrel, and crushing rods of equal length are evenly distributed on the upper part of the truncated cone around the axis of the truncated cone, and crushing rods of equal length are evenly distributed on the lower part of the truncated cone around the axis of the truncated cone. There is a connecting rod striking mechanism. This patent places the sand mold to be crushed and recycled into a barrel. The barrel rotates at high speed due to the drive of the motor. Under the action of the striking blocks on the inner wall of the barrel and the crushing rods on the upper part of the cone, the sand mold is broken into small pieces. When the small pieces of sand mold are located at the bottom of the barrel, the second connecting rod in the connecting rod striking mechanism breaks the small pieces of sand mold into fine particles again. Because the barrel is in a high-speed rotating state, the granular sand is finally formed into fine sand due to the action of centrifugal force. Finally, the fine sand passes through the sieve holes and falls into the material guide trough to achieve recycling.

[0005] However, there are still some problems that need to be improved in the actual use of the above patent. The most obvious one is that after the crushed and recovered sand mold is crushed, the fine sand can fall into the material guide trough through the sieve holes, while impurities and coarse sand will remain inside the barrel, which can easily cause the sieve holes to be blocked over time, which not only affects the filtering effect and efficiency of the fine yarn, but also makes it difficult to clean the sieve holes.

[0006] To this end, we proposed a crushing device for sand mold recovery to solve the above-mentioned drawbacks. Utility Model Content
