The set of dies shown in fig. 4 consists of four side dies, and two sets of side die limiting mechanisms are arranged on each side die, namely eight sets of side die limiting mechanisms are arranged on the set of dies.
A set of side form limiting mechanisms on a side form 1 will be described in detail below with reference to fig. 1 to 3.
The side die limiting mechanism comprises: the side die limiting block 3, the stop block 4 and the positioning pin 2.
As shown in fig. 2, the side mold 1 is provided with a side mold stopper mounting groove 100, a positioning pin mounting hole i 103 is provided on the bottom surface of the side mold stopper mounting groove 100, and a first threaded hole (not shown) is provided on the other side end surface. Correspondingly, the side die limiting block 3 is provided with a locating pin mounting hole II 102 and a first through hole.
In this way, the side mold stopper 3 can be positioned on the side mold 1 by inserting the positioning pin 2 into the positioning pin mounting hole i 103 and the positioning pin mounting hole ii 102, and fixed to the first screw hole of the side mold 1 via the first through hole by using a screw member (two are shown in fig. 2) such as a bolt or a screw. The lower end side of the side mold limiting block 3 protrudes downwards relative to the bottom surface of the side mold 1 to form a limiting part.
As shown in fig. 3, on the bottom plate 5 (also referred to as a die-carrier bottom plate) of the die-casting machine die carrier, a stopper mounting groove 101 is provided, and the stopper mounting groove 101 is opened toward the top die side while preferably being opened toward the lateral edge of the bottom plate 5.
At the side die advancing side bottom surface of the stopper mounting groove 101, a second screw hole (not shown) is provided. Accordingly, the stopper 4 is provided with a second through hole.
In this way, the stopper 4 can be fixed to the second screw hole of the stopper mounting groove 101 via the second through hole by screwing members (two are shown in fig. 3) such as bolts or screws, against the standing wall of the stopper mounting groove 101 on the side of the side mold advancing side. The side surface of the stopper 4 facing the stopper portion, that is, the side surface facing the lateral edge opening of the bottom plate 5 is formed as a stopper portion, and accordingly, the space of the stopper mounting groove 101 located laterally outside the stopper portion constitutes the forward and backward movement passage of the stopper portion of the side mold stopper 3.
As an example of the operation, when the die is closed, the cylinder of the die casting machine applies forward power to the side die 1, the limit portion of the side die stopper 3 advances in the stopper mounting groove 101, and when the limit portion of the side die stopper 3 contacts the stopper portion of the stopper 4, the side die 1 stops advancing, and the side die 1 is closed in place, thereby realizing the limit operation of the side die 1.
Preferably, the stop block 4 is made of H13 steel and is nitrided on the surface, so that the stop block is good in wear resistance and beneficial to prolonging the service life.
