Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Referring to fig. 1, fig. 2 and fig. 3 show, the utility model provides a low pressure casting mould side motion of loosing core, including the mould body, the mould body is by lower bolster 1, upper bolster 2, go up mold frame 3 and last mold core 4 and constitute, it is located 1 top of lower bolster to go up mold core 3, it has foundry goods 6 to go up mold core 4 through screw fixed mounting in last mold frame 3 lower part, it has foundry goods to cast between mold core 4 and the lower bolster 1, pour the casting material between the gap through last mold core 4 and lower bolster 1, then the pressfitting, can form foundry goods 6, be provided with the mechanism of loosing core on the lower bolster 1, the mechanism of loosing core includes core bar 7 and latched device, through-hole 6 has been seted up on 1 side surface of lower bolster, through-hole 6 link up in foundry goods 5 positions, loose core bar 7 activity is inserted and is located in through-hole 6, loose core bar 7 passes.

In this embodiment, the latch mechanism is including the fixed plate 8 of loosing core and the limiting plate 9 of loosing core, and the fixed plate 8 of loosing core is through round pin axle fixed mounting at 1 side surface of lower bolster, and the fixed plate 8 of loosing core has a determining deviation with 1 surface of lower bolster, and the width of its interval corresponds each other with the thickness of the limiting plate 9 of loosing core to can block the limiting plate 9 of loosing core, loose core fixed plate 8 is located the adjacent one side position of through-hole 6, loose core limiting plate 9 fixed cover is established on 7 surfaces of core pulling pole, loose core fixed plate 8 and loose core limiting plate 9 are the disc structure, loose.
