Embodiment Construction
[0015] See Figure 1~Figure 3 , The present invention is used to connect the sand shooting board 1 and the sand shooting head 2, and includes a snap locking device 3, a groove 4, a positioning pin 5 and a positioning pin locking screw 6. Two positioning pins 5 are provided in the length direction of the sand shooting board 1. The position of the positioning pin 5 corresponds to the position of the positioning pin hole opened on the sand shooting head 2. Each positioning pin 5 is fixed in the position by a positioning pin locking screw 6 Shot on the sand board 1. Grooves 4 are uniformly distributed on the entire edge of the sand-shooting board 1, preferably with a groove 4 at an interval of 160-250 mm. The edges of the connecting surface of the sand shooting head 2 and the sand shooting board 1 are evenly distributed with grooves 4, preferably with a groove 4 arranged at an interval of 160-250 mm, the sand shooting board 1 and the grooves 4 on the sand shooting head 2 The posi...

The invention relates to a device for quickly replacing a sand-shooting plate in sand-lined iron mould. The device is connected with the sand-shooting plate and a sand-shooting head. The device is characterized by comprising buckle locking devices, grooves, location pins and location pin locking screws; the two location pins are arranged in the length direction of the sand-shooting plate and corresponding to location pin holes formed in the sand-shooting head in position, and each location pin is fixed on the sand-shooting plate via the location pin locking screw; the grooves with the same width are respectively milled at the corresponding positions of the sand-shooting plate and the sand-shooting head, and a plurality of pairs of grooves are uniformly distributed on the whole sand-shooting plate and the whole sand-shooting head; and one buckle locking device is arranged on each pair of grooves, the lower end surface of each buckle locking device is retreated inwards on the lower end surface of the sand-shooting plate, and a gap is left between the buckle locking device and the sand-shooting plate. The device disclosed by the invention is convenient and fast to disassemble and assemble.
Description
Technical field [0001] The invention relates to a quick-change iron-type sand-coated sand-shooting board device, which can replace the sand-shooting board conveniently and quickly. Background technique [0002] As a new energy-saving and material-saving casting technology, iron-type sand-coated casting technology has been widely used in the production of large batches of small and medium castings. Its economy, product quality, and internal mechanical properties are better than ordinary sand casting. [0003] For the production of iron-type sand-coated casting, the sand-coating of the iron-shaped cavity is generally achieved by sand-shooting, that is, the coated sand in the shot cavity of the sand-shooting molding machine uses gas pressure to remove the coated sand from the sand-shooting board. Inject into the iron cavity to complete the sand-coated molding work. The sand-shooting holes on the sand-shooting board correspond to the iron-type sand-shooting holes one-to-one. In order...
