Abstract
The invention relates to a sand shooting hopper of a hot core box core making machine, wherein sand shooting holes are easy to be heated and bonded with sand, and the sand shooting hopper is blocked or unsmooth, and the sand shooting hopper is required to be shut down and manually cleaned.
Description
Technical Field
A sand shooting hole of a core making machine in the casting industry, in particular to a multi-head device.
Background
The product manufactured by Japan Stone seeder 17668 of the company and 844937-1 of Honeywell company of America is to make cores on an HBH2-10940 core making machine, a core mould of the core making machine is provided with 12 sand shooting holes with the diameter of phi 10, the number of the sand shooting holes is 9, 12 sand shooting holes can be made simultaneously, 9 sand shooting holes can be made simultaneously, 40 sand shooting holes with the diameter of phi 10 are also made on a sand shooting hopper of the core making machine, the distribution coordinates of the sand shooting holes are standardized, the sand shooting hopper of the core making machine descends to be attached to a mould during core making, and the corresponding sand shooting holes can be aligned with sand shooting ports on the mould to carry out sand shooting. The hot core box is adopted to heat the mould to solidify the core sand, so when the sand shooting hopper presses the mould, the heat of the mould can be transmitted to the surface of the sand shooting hopper contacted with the mould, when the precoated sand is shot into the mould through the sand shooting hole, a part of the core sand on the wall of the sand shooting hole can be solidified by heating, and can be adhered to the wall of the sand shooting hole, the sand sticking on the wall of the sand shooting hole becomes thick after a long time, the sand shooting hole becomes small and gradually blocks a sand shooting channel, at the moment, the machine is stopped to clean the sand shooting hole one by one, part of the sand shooting hopper is also cooled by water, residual sand is adhered, and the sand shooting hole of the sand shooting hopper needs to be cleaned.
Disclosure of Invention
The invention uses a pneumatic drive cleaning head, when the sand shooting bucket finishes sand shooting and moves to the upper part of the cleaning head in the clearance of the core making, the cleaning head is lifted pneumatically, and the cleaning head extends into the sand shooting hole to clean the residual sand without stopping and manually cleaning.
The technical scheme is that a multi-head cleaning device for cleaning residual sand of a sand shooting hole of a core making machine is arranged below a idle stroke stop position after sand shooting of a sand shooting hopper is finished. The cleaning head is arranged on the cleaning plate by threads, the coordinate position of the cleaning head is consistent with the sand shooting hole of the sand shooting hopper of the core making machine, the cleaning head is hollow, residual sand can fall conveniently, the cleaning plate is provided with a guide post which can move in a guide sleeve of a fixing plate, the cleaning plate is fixedly connected with a connecting seat at the end part of a piston rod of an air cylinder, the air cylinder is arranged in the middle of the fixing plate, the cleaning head is hollow and is provided with a phi 6 through hole, the air cylinder is controlled by an electromagnetic directional valve and an electrical signal of the core making machine, and the cleaning head automatically cleans the sand shooting hole once after each sand shooting.
The invention has the obvious effects that after the cleaning device is arranged at the idle stroke position of the sand shooting hopper of the core making machine, when the sand shooting hopper moves to the idle stroke position after sand shooting is finished, the cleaning device cylinder pushes the cleaning plate to ascend, the cleaning head extends into the sand shooting hole to clean residual sand, manual cleaning is not needed, the sand shooting hole is kept completely smooth, and sand shooting is not influenced.

Detailed Description
Cleaning head 1 is installed according to the screw thread for the regulation coordinate on cleaning plate 2, installs guide post 3 in cleaning plate 2 both sides, and guide post 3 slidable mounting is in the uide bushing 4 of fixed plate 5, and connecting seat 6 is used at cleaning plate 2 middle part, connects the piston rod 7 of cylinder 8, and the middle part at fixed plate 5 is installed to 8 terminal surfaces of cylinder, and cylinder 8 is controlled by the signal of telecommunication of core making machine through the solenoid directional valve.
