Embodiment 1

[0027] see figure 1 , as shown in the legend therein, a quantitative sanding mechanism of a core shooting machine, the core shooting machine has a lower frame 11 and an upper frame 12 located above the lower frame 11, the lower frame 11 is provided with a movable The above-mentioned quantitative sand adding mechanism includes a sand storage bucket 31, a first sand filling valve 32 and a vibrating motor 33, the sand storage bucket 31 is installed on the upper frame 12, and the first sand filling valve 32 is arranged on the sand storage The sand outlet of the bucket 31, the vibration motor 33 is installed on the outer wall of the sand storage bucket 31, the first sand adding valve 32 is an adjustable valve, the quantitative sand adding mechanism also includes a quantitative bucket 34, and the quantitative bucket 34 is connected through a weighing element 35 On the upper frame 12, the sand inlet of the quantitative bucket 34 is connected to the sand outlet of the sand storage buc...

Embodiment 2

[0038] The rest are the same as the first embodiment, the difference is that the above-mentioned first sanding valve is an electromagnetic valve, the above-mentioned weighing element is a weight sensor, and the above-mentioned automatic control device includes a controller, a first electromagnetic valve driver, a second electromagnetic driver and a motor driver, the weight sensor is connected to the input end of the controller, the first sanding valve is connected to the output end of the controller through the first electromagnetic valve driver, and the second sanding valve is connected to the output end of the controller through the second electromagnetic valve driver. connected to the output end of the above-mentioned controller, and the above-mentioned vibration motor is connected to the output end of the above-mentioned controller through the above-mentioned motor driver.

[0039] The following introduces a quantitative sanding method for a core shooter, using the quantita...

Embodiment 3

[0047] All the other are identical with described embodiment one, and difference is that above-mentioned quantitative sanding method comprises the steps:

[0048] (1) Close the above-mentioned second sand-filling valve, turn on the vibrating motor of the above-mentioned sand storage hopper, open the above-mentioned first sand-filling valve through the above-mentioned controller and air control valve driver, and adjust the valve port of the above-mentioned first sand-filling valve to the maximum amount of sand The diameter is DN, adding molding sand to the above-mentioned quantitative hopper, and the above-mentioned weighing element weighs the weight of the molding sand in the quantitative hopper in real time, and transmits the weighing result to the above-mentioned controller;

[0049] (2) When the weight of the molding sand in the quantitative hopper weighed by the weighing element reaches 15 / 24M, adjust the valve port of the first sand adding valve to 21 / 30DN through the abov...

Abstract

The invention discloses a quantitative sand adding mechanism of a core shooter. The core shooter comprises a lower rack and an upper rack located above the lower rack, wherein the lower rack is provided with a movable shooting head device. The quantitative sand adding mechanism comprises a sand storage hopper, a first sand adding valve, a vibrating motor and a quantitative hopper, wherein the sand storage hopper is mounted on the upper rack, the first sand adding valve is arranged at a sand outlet of the sand storage hopper, the vibrating motor is mounted on the outer wall of the sand storage hopper, the first sand adding valve is an adjustable valve, the quantitative hopper is connected onto the upper rack through a weighing component, a sand inlet of the quantitative hopper is connected with the sand outlet of the sand storage hopper through the first sand adding valve, a sand outlet of the quantitative hopper is provided with a second sand adding valve, the shooting head device is connected to the sand outlet of the quantitative hopper through the second sand adding valve when located in a sand adding position, and the sand adding process is not affected by the piling shape of molding sand and factors during valve closing. The invention further discloses a quantitative sand adding method of the core shooter adopting the quantitative sand adding mechanism.

Description

technical field [0001] The invention relates to a quantitative sand adding mechanism of a core shooting machine, in particular to a quantitative sand adding mechanism and a quantitative sand adding method of a core making machine. Background technique [0002] In the production process of the core making machine, for complex sand cores, the sand shooting conditions of the equipment are required to be very strict, and the basic requirements for the sand shooting conditions of the equipment are consistent. The main factors affecting the sand shooting conditions are the sand shooting pressure and the sand storage in the nozzle. In the working condition of the core shooter, the fluctuation of the sand shooting pressure of the equipment during production is basically small, so it is required that the amount of sand stored in the shooting head of the equipment should be kept basically the same during the production process. [0003] In the existing core making machine, in the quan...
