Embodiment Construction
[0018] see figure 1 and figure 2 shown, where figure 1 It is a structural schematic diagram of the thimble exhaust structure of the present invention, figure 2 It is a partially enlarged schematic diagram of the thimble exhaust structure of the present invention.
[0019] The thimble exhaust structure of the present invention includes:
[0020] The thimble body 10 is provided with several exhaust grooves at its upper end, each exhaust groove is spaced with the same length, and the depth of all exhaust grooves is equal;
[0021] There is a certain distance between the top of the thimble body 10 and the nearest exhaust groove 101 below, so that the exhaust groove will not be too close to the casting and be blocked by molten soup, and the exhaust effect can be achieved.
[0022] Optionally, the width of the exhaust grooves 102 is 3 mm, and the depth is 0.2 mm; if the exhaust volume is too large during the molding process, the width of the exhaust grooves can be increased. ...
