[0002] At present, the structure of the turning machine for self-hardening sand molding consists of a frame, a turning frame and a driving mechanism. After the sand mold or sand box enters the turning frame along the conveying roller, the driving mechanism drives the turning frame to rotate 180° to realize the sand mold or sand box. This kind of structure has no clamping device and is only suitable for sand molds or sand boxes with a single size or little change.

The invention discloses a hydraulic clamping box turning machine. The machine comprises a box turning clamping device, a beam rail and a hoisting balancing device, wherein the beam rail is clamped between guide wheels which are arranged on the upper parts of two clamping arms of the box turning clamping device; the hoisting balancing device is fixed above the middle part of the beam rail; the twoclamping arms of the box turning clamping device are provided with gear rack swing hydraulic cylinders which can drive turning plates to rotate 180 degrees from a horizontal state or rotate and resetto the horizontal state; the two clamping arms move along the beam rail through a synchronous chain and a single oil cylinder, so that the two clamping arms clamp or loosen sand molds or sand boxes with different span; and the hoisting balancing device is used for adjusting to balance the gravity centers of the sand molds or the sand boxes with the different span. Compared with the conventional box turning machine, the invention has the advantages that: the hydraulic clamping box turning machine has a simple structure, is multi-purpose, simplifies equipment, enhances the effect, and is suitable for various sand molds or sand boxes; and the whole machine is hydraulically controlled, so that clamping and box turning operation is stable, box turning efficiency can be greatly improved, and the labor intensity of workers is reduced.
Description
technical field [0001] The invention relates to a device for clamping and turning over sand molds or sand boxes after no-hardening sand molding, in particular to a hydraulic clamping and turning mechanism suitable for sand molds and sand boxes of various sizes. Background technique [0002] At present, the structure of the turning machine for self-hardening sand molding consists of a frame, a turning frame and a driving mechanism. After the sand mold or sand box enters the turning frame along the conveying roller, the driving mechanism drives the turning frame to rotate 180° to realize the sand mold or sand box. This kind of structure has no clamping device and is only suitable for sand molds or sand boxes with a single size or little change. Therefore it is very necessary to develop a kind of clamping and turning device that uses one machine with multiple functions and is suitable for many kinds of sand molds or sand boxes. Contents of the invention [0003] The task...
