An oil press die comprising: the mold comprises a static mold 1, a movable mold 2, a sliding block 3, at least one connecting part 4 and a spring 5.

The static mold 1 is a male mold and is subsequently fixed on the oil press and is static relative to the oil press.

The movable mould 2 is a female mould, and a hydraulic cylinder 9 arranged on the oil press in the follow-up mode can move up and down relative to the oil press and is close to or far away from the stationary mould 1. The movable die 2 includes: a base body 2-1 with a die cavity 2-1A and a top block 2-2. An embedded groove 2-1B for the entry of the top block 2-2 is arranged on the first inner wall of the bottom surface of the die groove 2-1A. When the top block 2-2 is embedded in the groove 2-1B, the top surface of the top block 2-2 is coincident with the first inner wall, i.e. the movable mold 2 can be matched with the static mold 1.

The base body 2-1 is provided with a chute 2-1C below the die cavity 2-1A, the chute 2-1C is connected with the slide block 3 in a vertical sliding way, and the slide block 3 is connected in the chute 2-1C in a vertical sliding way. Specifically, the first linear guide rails 6 can be fixedly connected to the vertical inner walls on two sides of the sliding block 3, and the sliding block 3 is fixedly connected to first connecting blocks matched with the first linear guide rails 6. In addition, the length of the slider 3 is set so that both ends in the horizontal direction of the slider 3 pass out of the base body 2-1 from the slide grooves 2-1C to form two pass-out portions 3A.

Alternatively, the bottom of the chute 2-1C may not penetrate the base 2-1, and the stability of the base 2-1 as a whole is good, but the assembly of the slider 3 is inconvenient.

Optionally, the bottom of the chute 2-1C penetrates through the base body 2-1, and the bottom surface of the base body 2-1 is also fixedly connected with a reinforcing plate 7. I.e. the assembly of the slide 3 is completed, and then the reinforcement plate 7 is fixedly connected to the bottom surface of the base 2-1 by means of screws. The assembly of the sliding block 3 is convenient, and the overall stability of the base body 2-1 is also good.

The base body 2-1 has a through hole 2-1D provided between the die cavity 2-1A and the slide groove 2-1C, and the number of the through holes 2-1D is the same as the number of the connecting portions 4 (one example is shown in the drawing). The upper end of connecting portion 4 wears out and fixed connection in kicking block 2-2 from wearing out hole 2-1D, and the lower extreme fixed connection of connecting portion 4 is in slider 3, and specifically, connecting portion 4 and kicking block 2-2 can set up integratively, accomplishes fixed connection through the screw between connecting portion 4 and the slider 3.

A spring 5 is provided between the slider 3 and the base body 2-1 for keeping the slider 3 at a lower limit so that the top block 2-2 is held in the insertion groove 2-1B.

Alternatively, the number of the springs 5 is the same as the number of the connection parts 4, and is sequentially sleeved on the connection parts 4. The spring 5 is sleeved into the connecting part 4, and then the connecting part 4 is fixedly connected with the sliding block 3. Thus, the assembly of the spring 5 is relatively easy, and the spring 5 is relatively stable in the compression process.

Thus, the movable die 2 is coupled to the slider 3 by the up-and-down movement relative to the hydraulic press. When the movable die 2 is at the middle position, a workpiece is placed in the die cavity 2-1A; when the movable die 2 is closest to the static die 1, the movable die and the static die 1 finish stamping the workpiece; when the movable die 2 is furthest away from the static die 1, the ejector block 2-2 is ejected out of the die cavity 2-1A against the spring 5, and the workpieces in the die cavity 2-1A are ejected out together.

An oil press comprising: the hydraulic press comprises an equipment frame 8, a hydraulic cylinder 9, the hydraulic press die and two propping parts 10.

The equipment rack 8 includes: an upper mounting portion 8-1, a lower mounting portion 8-2, and a plurality of connecting rods 8-3.

The hydraulic cylinder 9 is fixedly connected to the lower mounting portion 8-2, and a piston rod is vertically upwards.

The bottom of the sliding groove 2-1C penetrates through the base body 2-1, the bottom surface of the base body 2-1 is fixedly connected with the reinforcing plate 7, and the reinforcing plate 7 can be fixedly connected with the top end of the piston rod.

The two propping parts 10 are fixedly connected to the lower mounting part 8-2 and respectively positioned right below the penetrating parts 3A at the two ends of the sliding block 3. Thus, when the movable die 2 is at the middle position, the workpiece is placed in the die cavity 2-1A; when the movable die 2 is limited at the upper side, the movable die and the static die 1 finish stamping the workpiece; when the movable die 2 is limited at the lower side, the ejector block 2-2 is ejected out of the die cavity 2-1A against the spring 5, and the workpieces in the die cavity 2-1A are ejected out together. Namely, in the process that the piston rod is retracted from the upper limit position to the lower limit position, the two propping parts 10 and the two-end penetrating parts 3A of the sliding block 3 are separated from each other, and then the sliding block 3 is driven to move upwards against the spring 5, so that the ejector block 2-2 is ejected from the die cavity 2-1A, and correspondingly, in the middle position, the two propping parts 10 and the two-end penetrating parts 3A of the sliding block 3 are separated.

Optionally, the oil press further comprises: a guide rail 11 and a first drive.

The guide rail 11 is fixedly connected to the penetrating part 3A at one end of the sliding block 3, and the inclined upper end is aligned with Yu Dingkuai-2. The first drive is fixedly arranged at the other end of the sliding block 3 and penetrates out of the part 3A to be aligned with the top block 2-2. Namely, when the upper limit and the middle position are reached, the material guide rail 11 and the first drive do not exceed the top surface of the movable die 2; when the lower side is limited, the material guide rail 11 and the first drive and the workpiece are together out of the top surface of the movable die 2, and the first drive is used for feeding the workpiece into the material guide rail 11 to complete automatic discharging.

Alternatively, the first drive is a cylinder 12. By the extension of the piston rod, it is moved against the workpiece and pushed into the guide rail 11.

Alternatively, the first drive is an air nozzle 13. When the workpiece is small and light, the air nozzle 13 sprays air to blow the workpiece into the material guiding track 11.
