Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting production, in particular to a vibrating sand-dropping and blank-removing device for sand casting. Background Art
[0002] In the casting process of cast iron parts, it is necessary to use an aluminum mold to cast a sand mold with the same shape as the product. By pouring molten iron into the sand mold, the product is formed in the sand mold, and then the sand outside the molded product is removed. In the casting process, a sand drop machine is often used, which uses vibration and impact to separate the sand and casting in the mold.
[0003] The existing technology has the following problems:
[0004] Most of the existing vibrating sand-falling machines are not equipped with a cooling mechanism, so that the temperature of the molding sand after separation from the casting is relatively high, and the molding sand needs to be cooled before it can be reused, resulting in a low reuse rate of the molding sand.
[0005] Therefore, we proposed a vibrating sand-falling and billet-removing device for sand casting to solve the above-mentioned drawbacks. Utility Model Content
[0006] The utility model aims to solve the shortcoming of low reuse rate of molding sand in the prior art and proposes a vibrating sand falling and blank removing device for sand casting.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A vibrating sand-falling and blank-removing device for sand casting comprises a device body and a collecting box, wherein the device body is installed on the upper surface of the collecting box via a spring column, and a vibration motor is arranged on the side surface of the device body, a cooling hollow tube is arranged inside the device body, and shunt pipes are arranged at both ends of the cooling hollow tube, one of the shunt pipes is connected to a shunt water inlet pipe, one end of the shunt water inlet pipe is connected to a booster pump, and the water inlet end of the booster pump passes through and extends into the cooling box, the other shunt pipe is connected to a shunt water outlet pipe, a cooling cavity is opened inside the collecting box, and a shunt water inlet pipe and a shunt water outlet pipe are connected at both ends of the cooling cavity.
[0009] Preferably, a plurality of the cooling hollow tubes are provided, and the plurality of cooling hollow tubes are installed at equal distances inside the device body.
[0010] Preferably, a grinding motor is provided on the lower surface of the collecting box, and a grinding roller is installed at the output end of the grinding motor.
[0011] Preferably, a heat exchanger is provided on the outer side of the cooling box, and the heat exchange end of the heat exchanger passes through and extends into the cooling box.
[0012] Preferably, the lower surface of the collection box is provided with supporting feet.
[0013] Preferably, a control console is provided on the side surface of the collection box, and a controller is provided on the upper surface of the control console.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] (1) The utility model is provided with a device body, a collection box, a cooling box, a cooling chamber, a spring column, a cooling hollow tube, a vibration motor, a booster pump, a shunt water inlet pipe, a shunt outlet pipe and a shunt pipe. When in use, a mixture of molding sand and castings is placed in the device body, and then the vibration motor is started to make the device body vibrate to perform a vibration sand dropping operation. Then the booster pump is started to pump the coolant in the cooling box to the shunt water inlet pipe. A part of the coolant enters the cooling hollow tube along the shunt pipe, and another part of the coolant enters the cooling chamber from the shunt water inlet pipe. When the molding sand and castings are in the sand dropping operation, the molding sand passes through the cooling hollow tubes and transfers heat to the cooling hollow tubes in a low temperature state, thereby achieving an efficient initial cooling effect. Then the molding sand falls into the collection box, and under the action of the coolant in the cooling chamber, the molding sand enters a secondary cooling and cooling, which greatly improves the cooling and cooling effect of the device, facilitates the subsequent reuse of the molding sand, and greatly reduces the time difference in the use of the molding sand.
