AI Technical Summary
In existing horizontal sand core making machines, the sand storage hopper is prone to overflowing due to equipment vibration and valve closure issues, requiring manual cleaning and affecting efficiency and utilization.
Design a sand storage hopper for a horizontal sand core making machine. The hopper consists of a combination of a hopper bin, valves, baffles, sliding parts, connecting components, and elastic elements. The elastic elements keep the baffle closed, and the movement of the sliding parts is converted into the rotational movement of the baffle, ensuring that the coated sand enters the sand injection cylinder and preventing overflow.
This effectively prevents the coated sand from falling directly onto the equipment frame, eliminating the need for manual cleaning and improving the efficiency of the core making machine and the utilization rate of the coated sand.

Abstract
Claims
1. A sand hopper for a horizontal sand core making machine, characterized in that include: The hopper (1) has a discharge pipe (1a) at the bottom; Valve (2) is installed on the discharge pipe (1a); Baffle (3) is hinged to the outlet of the discharge pipe (1a); The sliding part (4) is slidably connected to the discharge pipe (1a) in a horizontal first direction; it includes: a horizontal section (41) and a vertical section (42) fixedly connected to the horizontal section (41). The bottom of the vertical section (42) extends downward beyond the baffle (3). The part extending beyond the baffle (3) is used to: abut against the sand-feeding cylinder (7) when it returns to the bottom of the hopper (1) and drive the sliding part (4) to move. A connecting member (5) is disposed between the sliding part (4) and the baffle (3); used to convert the linear motion of the sliding part (4) into the rotational motion of the baffle (3); The elastic element (6) is used to: keep the baffle (3) in a closed state blocking the opening of the discharge pipe (1a) and keep the sliding part (4) in a first position where the vertical section (42) is close to the discharge pipe (1a).
2. A sand hopper for a horizontal core making machine according to claim 1, characterized in that The connecting member (5) is a connecting rod (51), one end of which is hinged to the sliding part (4), and the other end is hinged to the baffle (3).
3. A sand hopper for a horizontal sand core making machine according to claim 2, characterized in that The baffle (3) has an extension (32) away from the discharge pipe (1a) at the hinge position with the discharge pipe (1a); the connecting rod (51) is at the extension (32) at the hinge position of the baffle (3).
4. A sand hopper for a horizontal sand core making machine according to claim 1, characterized in that The connecting component (5) includes: rack (53) and gear (52).
5. The sand storage hopper of a horizontal sand core making machine according to claim 4, characterized in that, The elastic element (6) consists of two sets, which act on the sliding part (4) and the baffle (3) respectively. When the baffle (3) is in the closed state and the sliding part (4) is in the first position, the rack (53) and the gear (52) are in the separated state.
6. A sand hopper for a horizontal sand core making machine according to claim 1, characterized in that The vertical section (42) can be adjusted along the first direction to the fixed connection position at the horizontal end.
