Embodiment 1

[0038] Such as Figures 1 to 5 As shown, the molding mechanism of the powder molding machine includes a frame 1 and a booster cylinder 2. The frame 1 includes an upper fixed plate 1a and a lower fixed plate 1b parallel to and opposite to the upper fixed plate 1a, an upper template 3 and a lower template 4 for positioning the mold 13 are arranged between the upper fixed plate 1a and the lower fixed plate 1b , there are four guide posts 10 between the upper fixed plate 1a and the lower fixed plate 1b, and the two ends of the guide posts 10 are fixedly connected with the upper fixed plate 1a and the lower fixed plate 1b respectively, and the guide posts 10 pass through the upper formwork 3. The guide pillars 10 all pass through the upper template 3, so that the lifting of the upper template 3 has a better guiding effect. As another way, the lower template 4 and the lower fixing plate 1b adopt an integral structure. The number of guide pillars 10 can be 2 or 6.

Embodiment 2

[0045] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Figure 6 As shown, the blocking member 6 is a blocking rod 6b arranged parallel to the upper fixing plate 1a, the blocking rod 6b is located on the lower side of the through hole 1a1, one end of the blocking rod 6b is hinged on the upper fixing plate 1a and the blocking rod 6b can rotate horizontally . The driving mechanism 7 is a cylinder 7a whose cylinder body is hinged on the upper fixed plate 1a. The piston rod of the cylinder 7a is arranged horizontally, and the piston rod of the cylinder 7a is hinged with the other end of the stop rod 6b. The blocking rod 6b is driven to rotate by the cylinder 7a to realize the blocking of the upper end of the cylinder body of the pressurized oil cylinder 2, which has the advantage of simple structure and convenient blocking.

Embodiment 3

[0047] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Figure 7 As shown, the upper end of the cylinder body of the pressurized oil cylinder 2 is vertically provided with a bar-shaped retaining post 11, the bar-shaped retaining post 11 passes through the through hole 1a1, the bar-shaped retaining post 11 can abut against the blocking member 6, and the pressurized oil cylinder 2 The upper end of the cylinder block is fixedly connected with a bar-shaped retaining column 11, so that when the upper template 3 is lowered for a larger displacement, the stopper 6 can lean against the bar-shaped retaining column 11 to realize the positioning of the cylinder body of the pressurized oil cylinder 2.

Abstract

The invention provides a die pressing mechanism of a powder forming machine, and belongs to the technical field of mechanical equipment. The die pressing mechanism of the powder forming machine solves the problem that a die pressing mechanism of an existing powder forming machine is not ideal in pressing effect. The die pressing mechanism of the powder forming machine comprises a rack and a booster oil cylinder, the rack comprises an upper fixing plate and a lower fixing plate which is parallel and opposite to the upper fixing plate, an upper die plate and a lower die plate are arranged between the upper fixing plate and the lower fixing plate, a cylinder body of the booster oil cylinder is vertically and fixedly connected to the upper die plate, a piston rod of the booster oil cylinder faces down and penetrates through the upper die plate, the lower end of the piston rod of the booster oil cylinder can be fixedly connected with a die head, the cylinder body of the booster oil cylinder can penetrate through the upper fixing plate, the upper fixing plate is further provided with a lifting mechanism, the upper fixing plate is provided with a blocking piece and a driving mechanism, and the driving mechanism can drive the blocking piece to move horizontally so as to enable the upper end of the cylinder body of the booster oil cylinder to abut against the blocking piece. The die pressing mechanism of the powder forming machine has the advantage of being ideal in pressing effect.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a powder forming machine, in particular to a compression molding mechanism of the powder forming machine. Background technique [0002] The workpiece made of polytetrafluoroethylene powder die-casting has simple manufacturing process and low manufacturing cost. Therefore, powder compression molding machines are widely used in machining. Generally, a powder compression molding machine includes a mold and a stamping head located on the upper part of the mold, and the powder raw material at the mold can be pressed into shape by pressing down the stamping head. [0003] For example, a hydraulic powder forming machine [application number: 201320584307.1; authorized announcement number: CN203449634U] proposed in the Chinese patent literature, including a frame, four guide pillars are vertically arranged on the frame, and the guide pillars are slid up and equipped with The ...
