It is widely used in aerospace, automobile manufacturing, mechanical engineering, construction and electronic equipment. Among them, core making involves high-precision technology and complex equipment, and is a vital part of the modern electronics industry.

[0003] After searching, it was found that the Chinese patent with application number 202320303968.6 discloses a device for making inner cavity sand cores for casting, including: a chassis, a control structure fixedly connected to the top of the chassis, the control structure is connected to the bottom of the sealed cavity through two pipes, the sealed cavity is fixedly connected to the top of the chassis, and an elastic structure is provided in the sealed cavity. The device for making inner cavity sand cores for casting is provided with a control structure, an elastic structure, a movable plate, a switch and an alarm. When the staff steps on the control structure, the movable plate can be driven upward by the inflatable jacking elastic structure so that the movable plate corresponds to the position of the block. At this time, the staff takes out the finished product. If the electric push rod switch is accidentally touched or its control system loses control, causing the heating mold cavity to close, so that the block is blocked by the top of the movable plate, and the switch is triggered to control the alarm to sound an alarm, which can remind the staff to stay away and ensure the safety of the staff in taking materials.

[0006] 2. The staff is required to step on the upper plate and then exhaust the air bag to take out the core, which is time-consuming and laborious. Utility Model Content

[0007] The purpose of the present invention is to provide an efficient core making device for casting to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

The lifting and picking structure is fixedly connected to one side of the notch on the top of the base plate, and a support column is fixedly connected to the other side of the top of the base plate. A controller is installed on one side of the support column, a pressure sensor is provided on the upper part of one side of the support column, and the movable structure is fixedly connected to the recessed position on the top of the support column.

[0010] As a further solution of the present invention: the moving structure includes a first motor, a fixed frame, a sliding frame and a threaded rod, the sliding frame is fixedly connected to one side of the inner wall of the fixed frame, a threaded rod is rotatably connected between the fixed frame and the support column, and one side of the threaded rod passes through one side of the support column and is fixedly connected to the power output shaft of the first motor.

[0011] As a further solution of the present invention: the lifting and picking structure includes a second motor, a first fixed plate, a second fixed plate, a gear, a rack and a slide groove. The second motor is fixedly connected to the recessed position on the top of the first fixed plate. The power output shaft of the second motor is fixedly connected to a circular shaft. The side of the circular shaft away from the second motor passes through one side of the gear and is rotatably connected to the second fixed plate. The gear is fixedly connected to the circular shaft, and one side of the gear is meshed with a rack. Slide grooves corresponding to the slides on the first fixed plate and the second fixed plate are opened on both sides of the rack, and the slide grooves are slidably connected to the slide.

[0012] As a further solution of the present invention: the sliding frame and the threaded rod on the movable structure are connected with corresponding moving blocks, the moving block on one side is provided with a sliding groove corresponding to the sliding frame, and the sliding groove is slidably connected to the sliding frame, the moving block on the other side is threadedly connected to the threaded rod, and a core shooting machine is fixedly connected between the two moving blocks; an acceleration sensor is provided inside the core shooting machine, and a solenoid valve is detachably connected to the feed pipe at the bottom of the core shooting machine, a diversion pipe is fixedly connected to the bottom of the feed pipe, and three discharge pipes corresponding to the mold cavity are threadedly connected to the side of the diversion pipe away from the feed pipe.

[0013] As a further solution of the present invention: a connecting plate is fixedly connected between the top of the base plate, the lifting and picking structure and the support column, a number of casting columns of different sizes arranged at equal intervals are fixedly connected to the top of the connecting plate, and a heating template is fixedly connected to the side of the rack on the lifting and picking structure away from the gear.

[0014] As a further solution of the present invention: a sensor is provided inside the heating template, and a number of mold cavities of different sizes and arranged at equal intervals are opened on the top of the heating template.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During use, turn on the first motor, which drives the threaded rod to rotate. The rotation of the threaded rod and the sliding action of the sliding frame and the sliding groove drive the movement of the two moving blocks, which in turn drives the movement of the core shooter. The movement of the core shooter facilitates the injection of core-making material into the mold cavity, thus preparing for the next step of core making.

[0017] 2. When the core shooter moves to the appropriate position and stops, the acceleration sensor inside it will transmit data to the controller, which will drive the solenoid valve to open, so that the core-making material falls from the feed pipe to the inside of the diversion pipe, and finally falls into the corresponding mold cavity through the corresponding discharge pipe. The template is then heated and formed. When the core shooter moves, the acceleration sensor will transmit new data to the controller, which will close the solenoid valve until the core shooter touches the pressure sensor. The pressure sensor sends data to the controller, which will completely close the first motor and the solenoid valve. This operation is conducive to batch casting cores of different specifications;

[0018] 3. When the core in the mold cavity is formed, the sensor in the heating template will send data to the controller, which will turn on the second motor. The second motor drives the rotation of the circular shaft, which in turn drives the rotation of the gear on the circular shaft. The rotation of the gear drives the longitudinal movement of the rack. When the rack moves downward, it also drives the downward movement of the heating template, so that the casting column passes through the mold cavity. On the one hand, this operation is conducive to adjusting the length of the cast core. On the other hand, when the casting column completely passes through the mold cavity, it will eject the molded product in the cavity, making it easier for the staff to take it.
