When a feature is referred to as being "disposed," "secured" or "connected" to another feature, it can be directly disposed, secured or connected to the other feature or it can be indirectly disposed, secured or connected to the other feature.
Referring to fig. 1, the application provides a technical scheme of an automatic turnover mechanism for a cold box loose piece in sand casting, which comprises the following steps: the utility model provides an automatic tilting mechanism of cold core box loose piece in sand casting, including last core box 1, lower core box 2, evacuation side take out loose piece 3, psammitolite 4, compression spring 5, rotatory loose piece 6 and rotatory loose piece fixing base 8, go up core box 1 below and be provided with lower core box 2, go up core box 1 and be provided with not less than one psammitolite 4 down between the core box 2, psammitolite 4 middle part is provided with evacuation side take out loose piece 3, psammitolite 4 both sides are provided with rotatory loose piece 6, rotatory loose piece 6 middle part and rotatory loose piece fixing base 8 rotate and are connected, offer the first cavity that holds rotatory loose piece fixing base 8 on the lower core box 2, rotatory loose piece 6 back lower extreme is provided with compression spring 5.
Specifically, the compression spring 5 is in a maximum compression state when in use, so as to provide rotary power for the rotary loose piece 6 when the die is opened, and the rotary loose piece fixing seat 8 can limit and fix the position of the rotary loose piece 6.
When the die is opened, the evacuating side extracting block 3 is firstly extracted, the upper core box 1 is opened, then the sand core 4 is rotated under the action of the compression spring 5 in the ejection process of the lower ejector rod until the sand core is ejected, the rotation block 6 does not rotate when being contacted with the rotary block fixing seat 8 on the back, at the moment, the compression spring 5 still has precompression, and the rotary block 8 does not interfere with the demolding of the sand core 4.
