Specifically, the atomizing nozzles 95 are designed to be inclined on the surface of the top cap 94, and the inclined directions of the atomizing nozzles face the inner wall of the core box 3;
when the mold is in operation, the airflow mixed mold release agent is sprayed to the inner wall of the core box 3 through the atomizing nozzle 95, and then the circulating pipe 25 positioned in the middle of the top cap 94 is matched to form a complete airflow direction in the inner cavity of the core box 3, so that the uniform coating of the mold release agent on the inner wall of the core box 3 is effectively enhanced;
the working principle is as follows: when the core box 3 needs to be installed, the groove on the lower surface of the core box 3 is aligned with the cylindrical rod 7 to slide downwards, the cylindrical rod 7 is tightly attached to the groove on the lower surface of the core box 3, the top end of the cylindrical rod 7 can prop against the telescopic head 82, the top end of the cylindrical rod 7 of the core box 3 is continuously pressed downwards, the telescopic head 82 can continuously push the telescopic head 82, the telescopic head 82 pushes the fixed rod 83 to drive the spring 85 on the fixed rod 83 to deform, when the U-shaped groove 81 and the telescopic head 82 are in a horizontal position, the telescopic head 82 drives the telescopic head 82 to enter the U-shaped groove 81 to be clamped tightly because the spring 85 needs to restore to deform at the moment, the core box 3 and the fixed plate 2 are tightly fixed, the core box 3 can be fixed without screws, the problem of cockamamie screws is avoided, when the core box 3 needs to be disassembled, only the iron ring 84 needs to be pulled to enable the hole groove 10 on the fixed rod 83 to leak out, then the fixed rod 83 is inserted into the hole groove 10, and the fixed rod 83 pulls the telescopic head 82 to separate from the U-shaped groove 81, an operator can take up the sand core box 3 to separate the sand core box 3 from the fixed plate 2 and then take down the thin cylindrical iron rod in the hole groove 10, so that the sand core box 3 can be easily disassembled, the problem of complex screwing is avoided, the replacing speed of the sand core box 3 is accelerated, the working efficiency is improved, when the fixed plate 24 is driven by the first air cylinder to approach to the direction of the fixed plate 2, the slide rod 6 is further moved to the inner cavity of the extension tube 61, the compression bag 62 positioned in the inner cavity of the extension tube 61 is extruded, the extruded compression bag 62 conveys the internal gas to the extrusion bag 23 through the conduit, the extrusion bag 23 positioned in the guide tube 21 is inflated and expanded, the inflated and expanded extrusion bag 23 extrudes the clamping plates 22 in the guide tube 21, the clamping plates 22 slide in the guide tube 21 to the direction of the sand core box 3 until the clamping plates 22 positioned at two sides of the sand core box 3 clamp the sand core box 3, the pressure sensing switch 24 arranged on the clamping plate 22 is acted by pressure, and then the air compressor is controlled to start through an electric signal, after the air compressor is started, airflow is stably conveyed to the inner cavity of the connecting rod 91, the airflow is guided through the inner cavity of the connecting rod 91 and finally enters the inner cavity of the sand core box 3, and the inner cavity of the sand core box 3 is cleaned, so that residual molding sand, impurities and the like in the inner cavity of the sand core box 3 are prevented from staying, and further negative influence is caused on the remanufacturing of sand cores, meanwhile, as the fixing plate 24 continuously draws close to the direction of the fixing plate 2, after the sand core box 3 on the fixing plate 24 and the sand core box 3 on the fixing plate 2 are folded, the airflow guided through the connecting rod 91 and entering the sand core box 3 cannot diffuse to the outside, and further the internal pressure of the sand core box 3 is increased, the increased air pressure finally forces the circulating pipe 25 to be conducted and enters the release agent tank 96 through the circulating pipe 25, and the pressure in the release agent tank 96 is increased, the release agent is caused to flow along the air pipe 93, when the release agent moves to the end part of the air pipe 93, the air pipe 93 is conducted under the action of pressure, and then the release agent enters the inner cavity of the connecting rod 91 and is sprayed to the inner cavity of the sand core box 3 through the atomizing nozzle 95 on the top cap 94 under the wrapping action of air flow;
although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
