Description

Technical Field

[0001] The utility model relates to the technical field of core shooting, in particular to a double-shooting head core shooting machine for casting production. Background Art

[0002] Core shooting machines are widely used in the foundry industry. The cores made by core shooting machines are precise in size and smooth in surface. The working principle of the core shooting machine is to inject a core sand mixture with liquid or solid thermosetting resin as a binder into a heated core box. The sand core is preheated in the core box and quickly hardened to a certain thickness before being taken out to form a high-quality sand core product with a smooth surface and precise size. When core shooting for different workpieces, different molds are used to fix the workpieces, and the position of the core injection may also be different depending on the workpiece.

[0003] A search for the above-mentioned problem revealed that, in the currently disclosed prior art, there is a core shooting machine proposed in publication number CN218744731U. The device opens a groove on the upper surface of the workbench, installs a threaded rod and a slide rail in the slide groove, and opens a slide groove and a threaded hole at the bottom end of the block, so that it can move forward and backward in the groove of the workbench, and a groove is opened on the surface of the block for placing the workpiece and the mold. The structure of different blocks is selected according to different workpieces. A base is installed at one end of the workbench, and a driving motor is arranged above the base. The threaded rod is connected to the driving motor, thereby driving the mounting plate on the threaded rod and the core shooting mechanism to move up and down. Multiple groups of fixed rods are installed in the middle of the base, and an adjustment mechanism is installed on the outer side of the fixed rod. The output end of the adjustment mechanism is connected to the core shooting machine to control its forward and backward movement, so that the position of the core injection can be adjusted. However, after the core injection is completed, the workpiece needs to be taken out of the mold. If it is taken out manually, it is very likely to damage the workpiece that has just been injected, resulting in incompleteness of the workpiece and waste of raw materials. Utility Model Content
