Technical Field
The utility model belongs to the technical field of the die casting die frock, a die casting die assembly and disassembly tools is related to, concretely relates to special assembly and disassembly tools of preceding planting core.
Background
In large-scale die casting die, because of the restraint of product structure, need plant the core structure before the assigned position design specification and dimension is different, this kind of plant core structure before be convenient for machining and shortened the mold's processing cycle greatly and promoted mold output speed.
In the prior art, in order to conveniently install and screw the front planting core, a mode of reserving an auxiliary lengthening head at the head of the front planting core is adopted for screwing the front planting core, as shown in fig. 1 and 2, the auxiliary lengthening head needs to be removed after the front planting core is screwed, and a large amount of time is consumed when the auxiliary lengthening head is removed. And according to the position of planting the core before installing different, it still can't use the spanner screw in to screw up the preceding core of planting to go out the complex department of deep cavity department shape, as shown in fig. 3, because the preceding core of planting is secretly changeed and is transshipped the deep cavity work piece inside, the spanner can't go deep into the deep cavity inside and operate. When the installation structure is met, the problems can be solved only by changing the design structure of the die, so that the time and the labor are consumed, and the manufacturing cost of the die is greatly increased.
