Description

Technical Field

[0001] The utility model relates to the technical field of core shooting machines, in particular to a material feeding device for coated sand core shooting machines. Background Art

[0002] The coated sand core shooting machine is a device that uses coated sand as raw material and uses the hot core box principle to make coated sand cores. The coated sand core shooting machine is widely used in the foundry industry. The sand cores made by the coated sand core shooting machine are accurate in size and smooth in surface. The working principle of the coated sand core shooting machine is to shoot the core sand mixture with liquid or solid thermosetting resin as binder into the heated core box. The sand core is preheated in the core box and quickly hardens to a certain thickness before being taken out, forming a high-quality sand core product with a smooth surface and accurate size. The products produced by the core shooting machine need to be collected using a feeding device.

[0003] At present, the factory produces coated sand core shooting machines. After the core shooting machine is finished, the product needs to be taken out of the mold. The existing method is that the staff uses tools to buckle the product out. This method of unloading will affect the production efficiency of the core shooting machine, making it inconvenient to use.

The gravity of the gravity block 15 will press the push rod 16 downward, thereby ejecting the product in the mold 2 7 onto the conveyor belt 8, thereby unloading the produced product, thereby improving the production efficiency of the equipment.

[0022] like Figure 1 and Figure 3 As shown, a mounting plate 3 is fixedly connected to the other side of the support frame 1, a driving cylinder 4 is fixedly installed on one side of the mounting plate 3, a mold 6 is fixedly connected to the output end of the driving cylinder 4, both sides of the mold 6 are slidably connected with limiting rods 12, a fixing frame 2 is fixedly connected to the inner bottom of the support frame 1, two limiting rods 12 are respectively fixedly connected to one side of the support frame 1 and the fixing frame 2, and the limiting rods 12 are used to limit the sliding of the mold 6 to prevent the mold 6 from being misaligned with the mold 2 7 due to long-term use of the mold 6.

[0023] like Figure 1 and Figure 3 As shown, the inner wall of the support frame 1 is slidably connected with a sand core shooting machine body 5, and the output ends of the sand core shooting machine body 5 are slidably connected with the upper ends of mold 1 6 and mold 2 7 respectively.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a conveyor belt 8 is provided below the mold 2 7, and mounting plates 2 9 are fixedly connected to both sides of the conveyor belt 8. The lower ends of the two mounting plates 29 are fixedly connected to the inner bottom of the support frame 1.
