Embodiment 1

[0035] Such as Figure 1-6 As shown, a powder metallurgy mold with double compaction includes a base box 1, a lower extrusion mold 3 and an upper extrusion mold 4, the lower extrusion mold 3 is installed on the base box 1, and the base box 1 is horizontally The right-angled trapezoidal groove 2 with the hypotenuse facing the outside and the bottom being a narrow side is symmetrically arranged on the two end plates. The bottom of the right-angled trapezoidal groove 2 is equipped with a first rotating block 11, and a first hydraulic rod 12 is installed on the first rotating block 11. The top of the first hydraulic rod 12 is equipped with a lower locking tooth 13 whose tooth angle is inclined to the bottom of the middle of the base box 1. The right-angled trapezoidal groove 2 is provided to provide a rotation space for the rotation of the first hydraulic rod 12 to avoid the situation of rotation limitation. , the upper extrusion die 4 is installed on the bottom of the upper mount...

Embodiment 2

[0044] A method of operating a powder metallurgy mold with double compaction, comprising the following steps:

[0045] S1, adjust the positioning bolts 15 on both sides to laterally position the lower extrusion die 3 through the rotating sleeve 16, adjust the lifting device 8 to drive the lateral positioning of the upper extrusion die 4 at the lateral position of the side frame body 25, the positioning bolts 15 and the base The side panel of box 1 is threaded;

[0046] S2. Push the upper extrusion die 4 to move downward by controlling the lifting device 8, so that the annular sealing strip 6 at the bottom of the upper extrusion die 4 is inserted into the annular clamping groove 5;

[0047] S3. After the upper extrusion die 4 is initially matched with the lower extrusion die 3, the first rotating block 11 is driven to rotate by controlling the first servo motor 14, and the first rotating block 11 drives the first hydraulic rod 12 to rotate, and the first hydraulic rod 12 Drive...

Abstract

The powder metallurgy die comprises a base box, a lower extrusion die and an upper extrusion die, right-angled trapezoidal grooves are symmetrically formed in the two transverse ends of the base box, first rotating blocks are installed at the bottoms of the right-angled trapezoidal grooves, and first hydraulic rods are installed on the first rotating blocks; the top of the first hydraulic rod is provided with lower clamping teeth with tooth angles inclining towards the lower portion of the middle of the base box, the two ends of the upper installation frame are provided with upper clamping teeth in a front-back symmetry mode, the upper clamping teeth and the lower clamping teeth are installed in a meshed mode in the working process, door-type frame bodies are symmetrically installed on two longitudinal end plates of the base box, and the tops of the door-type frame bodies are provided with fan-shaped discs with the central angles equal to 180 degrees. Protruding blocks are symmetrically and fixedly connected to the opposite inner side ends of the front fan-shaped disc and the rear fan-shaped disc, second hydraulic rods are hinged to the opposite outer side ends of the front fan-shaped disc and the rear fan-shaped disc, and the bottom ends of the second hydraulic rods are rotationally installed on the door-type frame body.

Description

technical field [0001] The invention relates to the technical field of powder injection, in particular to a powder metallurgy mold with double compaction and an operation method thereof. Background technique [0002] When the metallurgical integral molding is used to prepare the workpiece, it is necessary to fasten the clamped mold. The existing fastening methods generally use bolts for installation and fastening. It is easy to loosen or shift during the integral molding process, resulting in poor molding quality. At the same time, multiple sets of bolts are used to fasten it. When removing the mold, it needs to be manually knocked and disassembled one by one, which consumes manpower and a lot of time. [0003] In view of the above problems, the present invention proposes a powder metallurgy mold with double compaction and its operation method. Contents of the invention [0004] In view of the problems in the above technical background, the purpose of the present inventio...
