Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 5, the three-head slider of the present utility model includes a positioning member 1, a jack 2, and a slider assembly 3.
The cross section of the positioning piece 1 is hexagonal, an inner six-hole 4 is arranged in the middle of the positioning piece, and the inner six-hole 4 penetrates up and down.
The ejector rod 2 is arranged in the middle of the inner six holes 4, and the ejector rod 2 consists of a first hexagonal part 5, a second hexagonal part 6 and a connecting part 7. The maximum thickness of the first hexagonal part 5 is greater than the maximum thickness of the second hexagonal part 6, and the connecting part 7 transitions from the straight surface of the first hexagonal part 5 to the second hexagonal part 6. The inner six holes 4 are matched with the first six sides 5.
The first hexagonal portion 5 has a certain length and can be connected to the movable die plate, and the connecting portion 7 connects the first hexagonal portion 5 and the second hexagonal portion 6 so as to move in the middle of the inner six holes 4. The second hexagonal part 6 is positioned in the fixed die plate and can slide in the middle of the fixed die plate.
When the connecting part 7 is positioned in the middle of the inner six holes 4, the ball head part 8 contacts with the connecting part 7, and when the top rod 2 changes the upper and lower positions, the position of the core pulling member 9 can be kept to be changed, so that the depth of the core pulling product is changed.
The sliding block assemblies 3 are uniformly distributed around the positioning piece 1, and the sliding block assemblies 3 are provided with three positions. The sliding block assembly 3 consists of a fixed seat 10, a core pulling member 9 and an elastic member 11, wherein a mounting hole 12 and an extending hole 13 are formed in the middle of the fixed seat 10, the mounting hole 12 is communicated with the extending hole 13, a matching part 14 is arranged on the core pulling member 9, the core pulling member 9 is arranged in the mounting hole 12 through the matching part 14, and the matching part 14 can slide in the mounting hole 12. The elastic member 11 is sleeved on the core pulling member 9, one end of the elastic member 11 is in contact with the matching portion 14, and the other end of the elastic member is in contact with the inner wall of the mounting hole 12.
