Description

Technical Field

[0001] The utility model belongs to the technical field of core shooting machines, in particular to a core shooting machine with a sand mixing structure. Background Art

[0002] The core shooting machine uses compressed air to evenly shoot the molding sand into the sand box for pre-compaction, and then applies pressure for compaction.

[0003] At present, a Chinese utility model with the publication number of CN216938320U discloses an improved sand mixing device for a core shooting machine. Its technical solution includes: a feeding arm, a base frame and a bottom box, a bottom box is installed on the top of the base frame, a load-bearing bearing is installed on the top of the bottom box, a box door is installed on the front of the bottom box through a hinge, a feed box is movably installed on the top of the bottom box through the load-bearing bearing, a feed hopper is installed on the top of the feed box, a first motor is installed on the outer side of the feed box, a feeding arm is installed on the outer side of the feed box, a discharge hopper is installed on the bottom side of the feeding arm, and an air pump is installed on the bottom side of the feeding arm. The utility model installs an air pump on the bottom side of the feeding arm, and the air pump can be powered on to pump gas into the discharge hopper, so that the sand particles are filled with gas and are in a loose state, which is convenient for the sand particles to be stirred and can also assist the sand particles to be mixed and easy to discharge, thereby improving the mixing efficiency of the device.

[0004] The existing core shooter needs to ensure that the molding sand is mixed evenly before being shot. However, due to the different particle sizes inside the different molding sands, some larger particles of molding sand are often mixed during mixing, which needs to be removed, resulting in low efficiency of sand mixing in the core shooter. At the same time, the nozzle of the existing core shooter is prone to clogging after long-term use, and the nozzle needs to be wiped and unblocked. The traditional cleaning method requires taking a brush to the bottom of the shooting head and wiping it. During the wiping process, the nozzle is easily damaged, so there are great safety hazards. Utility Model Content

[0005] The utility model aims to provide a core shooting machine with a sand mixing structure, which has the advantages of being convenient for removing molding sand with larger particles and cleaning the core shooting machine nozzle during the sand mixing process.

[0007] The above technical solution is adopted, and the motor is turned on to drive the stirring rod to rotate. The net tube is used to filter the molding sand poured into the sand tube and then stir and mix it, so as to achieve the effect of removing larger sand particles during the sand mixing process, improve the uniformity of molding sand particles, and facilitate subsequent sand shooting processing; the wiping cotton is driven by twisting the rotating cap to fit the bottom of the sand shooting nozzle to wipe the surface of the sand shooting nozzle. At the same time, the elastic force of the first spring is used to drive the conical block to extend upward, so as to dredge the inside of the sand shooting nozzle, which is not only convenient for cleaning the core shooting machine nozzle, but also eliminates the need to put your hand into the bottom of the nozzle, thereby improving safety.

[0008] The utility model is further configured as follows: a fixed cylinder is fixedly connected to one side of the support, a sliding rod is slidably connected to the inside of the fixed cylinder, a rotating cap is rotatably connected to the top of the sliding rod, a sand receiving plate is fixedly connected to one side of the rotating cap, a wiping cotton is adhesively fixedly connected to the sand receiving plate, a conical block is slidably connected to the inside of the wiping cotton, and a first spring fixedly connected to the sand receiving plate is installed at the bottom of the conical block.

[0009] The adoption of the above technical solution not only facilitates the cleaning of the core shooting machine nozzle, but also eliminates the need to put one's hand into the bottom of the nozzle, thereby improving safety.

[0010] The utility model is further configured as follows: a cylinder fixedly mounted on a support is arranged on one side of the sand cylinder, a sand shooting plate is fixedly connected to an output end of the cylinder, and a sand shooting nozzle is fixedly mounted on the bottom of the sand shooting plate.

[0011] By adopting the above technical solution, the sand shooting nozzle is driven to move up and down by using the sand shooting plate by opening the air cylinder, so as to fit the sand box for sand shooting.

[0012] The utility model is further configured as follows: the bottom of the sand cylinder is fixedly connected with a pressurized air valve, and the bottom of the pressurized air valve is fixedly connected with a hose fixedly connected with the sand shooting nozzle.

[0013] By adopting the above technical solution, pressurized air enters through the pressurized air valve, thereby pressurizing and spraying the molding sand that falls into the sand tube into the hose, so that it can be ejected from the inside of the sand shooting nozzle.

[0014] The utility model is further configured as follows: a support rod which is slidably connected to the support seat is penetrated inside the sand blasting plate.

[0015] The technical solution is adopted to improve the stability of the up and down sliding of the sand shooting plate, so that the sand shooting nozzle and the sand box can be easily fitted together.

[0016] The utility model is further configured as follows: a sand discharge port communicated with a sand discharge net pipe is fixedly connected to one side of the exterior of the sand cylinder.

[0017] The above technical solution is adopted to facilitate guiding the filtered large-particle molding sand to be discharged from the interior of the sand cylinder.

[0018] The utility model is further configured as follows: universal wheels are installed at four corners of the bottom of the support, and a locker is fixedly installed on one side of the universal wheel.

[0019] The above technical solution makes it easy to move the support and can also be fixed by a lock.

[0020] The utility model is further configured as follows: a second spring fixedly connected to the sliding rod is installed inside the fixing cylinder.

[0021] By adopting the above technical solution, the elastic force of the second spring is used to drive the sliding rod to slide downward inside the fixed tube, so that the sliding rod only needs to be pressed when the sand receiving plate is moved to the bottom of the sand shooting nozzle.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. Turn on the motor and use the rotating rod to drive the stirring rod to rotate. Use the net cylinder to filter the molding sand poured into the sand cylinder and then stir and mix it, so as to achieve the effect of removing larger sand particles during the sand mixing process, improve the uniformity of molding sand particles, and facilitate the subsequent sand shooting process;

[0024] 2. The wiping cotton is driven to fit the bottom of the sand shooting nozzle by twisting the rotating cap to wipe the surface of the sand shooting nozzle. At the same time, the elastic force of the first spring is used to drive the conical block to extend upward, so as to dredge the inside of the sand shooting nozzle, which is not only convenient for cleaning the core shooting machine nozzle, but also eliminates the need to put hands into the bottom of the nozzle, thereby improving safety.
