Embodiment 1

[0045] Embodiment 1: as Figure 4-5 As shown, the active part is the telescopic rod 5 of the oil cylinder or the cylinder, and the end of the telescopic rod 5 is directly fixedly connected with the first half nut 2. Specifically, the end of the telescopic rod 5 is fixed with an enlarging head, and the enlarging head is connected with the first half nut 2. The first half nut 2 fits and is fastened by bolts. The passive part is the cylinder liner 6 of the oil cylinder or the cylinder, and the cylinder liner 6 is fixedly connected with the second half nut 3 . The telescopic rod 5 is driven to telescopically slide in the cylinder sleeve 6 by a compressed medium, which may be compressed air or hydraulic oil.

[0046] At the same time, if Figure 1-3 As shown, the limiting structure includes at least one pair of limiting blocks 12, the first half nut 2 and the second half nut 3 are located between a pair of the limiting blocks, and the first half nut 2 and the When the second hal...

Embodiment 2

[0058] Embodiment 2: a kind of open and close fastening nut, such as Figure 1-3 As shown, the difference between it and Embodiment 1 is that in this embodiment, the active part is an air cylinder or an oil cylinder, and the end of the telescopic rod 5 of the air cylinder or oil cylinder is fixedly connected with the first half nut 2; the passive part is It is a fixed plate 7, which is fixedly connected with the second half nut 3.

[0059] Specifically, the fixed plate 7 is provided with a through hole, and one end of the telescopic rod 5 is located in the cylinder liner of the cylinder or the oil cylinder, and the other end passes through the hole and is connected with the first half nut, wherein the end of the telescopic rod 5 An enlargement head is fixed, and the enlargement head fits with the first half nut 2 and is fastened by bolts. The cylinder liner 6 of the air cylinder or oil cylinder is fixedly connected with the fixed plate 7, that is, the telescopic rod 5 will al...

Embodiment 3

[0066] Embodiment 3: An open-close fastening nut, the only difference from Embodiments 1 and 2 is that the passive part is a lead screw assembly containing a motor, and the active part is a slider threadedly connected to the screw rod. When the motor starts, The lead screw turns and the slider slides along the lead screw.

[0067] The slider is fixedly connected with the first half nut, the lead screw assembly includes a lead screw and a base plate, the motor is fixed on the base plate, and the base plate and the second half nut are also fixedly connected by two or four connecting rods. As for the specific setting of the connecting rod, it is the same as that of Embodiments 1 and 2, and will not be repeated here.

Abstract

The invention discloses an opening and closing type fastening nut and a die-casting machine. The fastening nut comprises a first half nut, the second half nut is attached to the first half nut to form a complete fastening nut; the opening and closing driving structure comprises a driving part and a driven part, the driving part is fixedly connected with the first half nut, the driven part is fixedly connected with the second half nut, when the driving part is driven, relative displacement is generated between the driving part and the driven part, and the displacement direction is the opening and closing direction of the first half nut and the second half nut; the limiting structure is arranged on an opening and closing path of the first half nut and the second half nut; the sum of the maximum opening and closing displacement of the first half nut and the maximum opening and closing displacement of the second half nut is equal to the relative displacement generated by the driving piece and the driven piece when the driving piece is driven. Through the arrangement, the stress generated when the split nuts are opened and closed is converted to the driven part and the driving part, the stress of the nuts is dispersed, and the service life of the nuts is prolonged.

Description

technical field [0001] The invention relates to the technical field of die-casting machine parts, in particular to a split-type fastening nut and a die-casting machine. Background technique [0002] At present, the most commonly used die-casting machine is the three-plate type, which is to connect three seat plates in series through four Corinthian pillars. Driven by the mold clamping mechanism to slide, the movable mold installed on the middle plate and the fixed mold installed on the head plate are driven to open and close the mold to complete the die casting. Since the fixed mold and the movable mold need to be installed, repaired and replaced, it is necessary to pass through the gap between the two Corinthian pillars during installation and disassembly, but in this way, the size of the mold will be limited by the gap between the Corinthian pillars , It also brings trouble to the installation and removal of the mold. [0003] To solve this problem, the traditional conne...
