Abstract

The utility model relates to a powder molding hydrodynamic press, which comprises a stander, and an upper die plate, a female die plate, a middle fixed die plate and a fixed die plate, wherein the upper die plate is provided with a central cylinder, the central cylinder is connected with an upper punch, the fixed die plate is provided with a lower punch, two sides of the lower end surface of the female die plate are provided with a small hydraulic oil cylinder in the horizontal direction, and the end part of the small hydraulic oil cylinder is connected with a limiting block. When in pressing, the small hydraulic oil cylinder is pushed out to be used for fixing and limiting, and when the work piece inside the female die is required to be demolded, the small hydraulic oil cylinder is withdrawn, the top cylinder which is connected with the female die plate pulls the female die plate to sink, so the work piece inside the female die can be pushed out of the female die cavity by the fixed lower punch so as to complete the demolding. The powder molding hydrodynamic press with the above structure can complete the press of the ladder-shaped work piece at one time, and is convenient to demold.

Description

A kind of hydraulic press for powder formation
Technical field
The utility model relates to a kind of hydraulic press for powder formation, comprise frame, and the cope match-plate pattern that sets gradually from top to bottom on the frame, negative template, middle fixed form, fixed form, described cope match-plate pattern is provided with central cylinder, be connected with upper punch on the piston rod of described central cylinder, be fixed with the low punch that passes fixed form in the top on the fixed form.
Background technology
Hydraulic press for powder formation is used for dusty material is pressed into pie, when the step-like metallic article of compacting, traditional method is by hydraulic press for powder formation dusty material to be pressed into pie, carry out the machining cutting again, production efficiency is low, and the clout after the cutting can't re-use, and causes waste material, has improved production cost.A kind of hydraulic press for powder formation is also arranged, it comprises the upper punch that is connected with little hydraulic jack, be fixed on the low punch on the frame, and the negative template between the last low punch, be connected with former in the negative template, directly make the inner chamber of former stepped, effect by last low punch and former once can be with powder pressing forming, but because former is step-like, former and negative template thereof can be subjected to downward impulsive force when upper punch pressed down, therefore must be provided with one fixing spacingly in the bottom of negative template, be used to support negative template.It exists shortcoming to be: low punch is for fixing, and negative template can't move down under fixing spacing effect, and causing suppressing the workpiece finished can't automatic demoulding, very inconvenient, influences production efficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of hydraulic press for powder formation of can a step-like pulverulent product of compression moulding and being convenient in demoulding.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hydraulic press for powder formation, comprise frame, and the cope match-plate pattern that sets gradually from top to bottom on the frame, negative template, middle fixed form, fixed form, described cope match-plate pattern is provided with central cylinder, the fixed form below is provided with takes blame for others, be connected with upper punch on the described central cylinder, be fixed with the low punch of fixed form in passing on the fixed form, its innovative point is: described negative template is connected with taking blame for others by guide pillar, and be provided with the little hydraulic jack of horizontal direction in the both sides, lower surface of described negative template, the end of described little hydraulic jack is connected with limited block.
Advantage of the present utility model is: but by the little hydraulic jack of horizontal direction is set in the negative template both sides, when compacting, little hydraulic jack ejects, serve as fixing spacingly, and the workpiece in the former is when needing the demoulding, and little hydraulic jack retreats, the pulling negative template of taking blame for others that is connected with negative template sinks, like this, the low punch that the workpiece in the former will be fixed ejects negative impression, finishes the demoulding.Adopt the hydraulic press for powder formation of this structure, can once finish the compacting of stepped workpiece, and be convenient in demoulding.
Description of drawings
Accompanying drawing is the mould bases structural representation of hydraulic press for powder formation of the present utility model.
The specific embodiment
As shown in drawings, the utility model relates to a kind of hydraulic press for powder formation, and it comprises cope match-plate pattern 1, negative template 2, middle fixed form 3, fixed form 4, central cylinder 5, limited block 6, former 7, take blame for others 8, guide pillar 9, lower bolster 10, little hydraulic jack 11.
Cope match-plate pattern 1 on the mould bases, middle fixed form 3 and fixed form 4 are from top to bottom, on the described cope match-plate pattern 1 central cylinder 5 is housed, the top of this central cylinder 5 is connected with upper punch, and the center fixation of fixed form 4 has the low punch that passes middle fixed form 3, and its below is provided with takes blame for others 8.
Negative template 2 is located between cope match-plate pattern 1 and the middle fixed form 3, and it 8 is connected with taking blame for others by guide pillar 9 and lower bolster 10.Little hydraulic jack 11 is located at the both sides of negative template 2, the top of middle fixed form 3, and its piston rod end is connected with limited block 6.When the piston rod of little hydraulic jack 11 ejected, limited block 6 was arranged in the top of fixed form 3, and when piston rod retreated, limited block 6 was arranged in a side of fixed form 3.
Former 7 is housed in the negative template 2, the inner chamber of this former 7 is stepped, during compacting, take blame for others and 8 promote negative templates 2 and former 7 rises, make former 7 and low punch constitute a cavity, in this cavity, add powder, simultaneously, the piston rod of little hydraulic jack 11 ejects, limited block 6 is placed the top of fixed form 3, like this, when upper punch is pressed into the ladder cavity of former 7 downwards, the limited block 6 of negative template 2 lower surfaces is against on the middle fixed die 3 of its below, bears the impact of upper punch to former 7 and negative template 2.After compacting was finished, the piston rod of little hydraulic jack 11 retreated, a side of fixed head 3 during limited block 6 retreats into, and the 8 pulling negative templates 2 of taking blame for others sink, and make that the workpiece in the former 7 is realized the demoulding under the effect of former 7 that sinks and fixed low punch.
