Abstract
Provided is a rubber die for sintering a neodymium iron boron magnet. The rubber die includes a body made of rubber materials, the body is square in shape, and a plurality of hoppers with an upper opening are uniformly distributed on the body. The rubber die is advantageous in that the rubber die replaces vacuum packaging to hold magnetic powder green compact, so that the rubber die can be recycled, saves resources, and is more convenient for operation; and the body is flexible in material because of being made of rubber materials, so that the quality problems of corner breaking and fracture of the magnetic powder green compact during the transportation of a packaging machine, and the product quality can be guaranteed.
Description
Technical field
The utility model relates to a kind of Sintered NdFeB magnet rubber pattern.
Background technology
In prior art, neodymium iron boron magnetic body needs magnetic to install in punching block before compacting, and then be put in moulding press the magnetic pressed compact that thereby punching block is carried out punching press and obtained compacting, magnetic pressed compact after compacting takes out and carries out vacuum sealing bag from mould, each magnetic pressed compact carries out vacuum sealing bag one time, operation is trouble very, and before sintering, also need to shell oily, peeling the envelope coming can not recycle, easily cause the wasting of resources, simultaneously, envelope can not play a protective role to magnetic pressed compact in packaging and transportation, easily there are the quality problems of product unfilled corner and fracture, cannot ensure the quality of product.
Summary of the invention
In order to overcome the Sintered NdFeB magnet rubber pattern that exists above-mentioned deficiency, the utility model that a kind of simple in structure, easy to operate, good product quality is provided in prior art.
The technical scheme in the invention for solving the technical problem is: a kind of Sintered NdFeB magnet rubber pattern, comprise the body of being made by elastomeric material, and this body is square, and is evenly equipped with multiple hoppers with upper shed on this body.
Further, also comprise that one is placed on the lid on described body, this lid is made up of elastomeric material, on the lower surface of this lid, evenly convex with the projection in multiple corresponding upper ends of stretching into described hopper one by one, the lower surface of this lid contacts with the upper surface of described body, the outer wall of described projection contacts with the inwall of described hopper, good sealing effect.
Further, the lower surface of described body is extended with location convex tendon downwards, in transportation, positions.
The utility model in use, magnetic obtains magnetic pressed compact after moulding press compacting, then magnetic pressed compact is put into the hopper of body, when all hoppers of body are filled after magnetic green compact, carry out oil packing in the outside of body by nylon again, remove wrapper through waiting after static pressure, in the hopper of body, take out magnetic green compact, then be put in sintering box and can carry out sintering.
The beneficial effects of the utility model are: adopt said structure splendid attire magnetic green compact, substituted Vacuum Package, can be recycled, saving resource, operates more convenient; And body adopts elastomeric material to make, material softness, can effectively avoid magnetic green compact in packing machine transportation, to occur the quality problems of unfilled corner and fracture, has ensured the quality of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of Sintered NdFeB magnet rubber pattern, comprises the body 1 of being made up of elastomeric material, and this body 1 is square, and is evenly equipped with multiple hoppers 2 with upper shed on this body 1.
Also comprise that one is placed on the lid 3 on described body 1, this lid 3 is made up of elastomeric material, on the lower surface of this lid 3, evenly convex with the projection 4 in multiple corresponding upper ends of stretching into described hopper 2 one by one, the lower surface of this lid 3 contacts with the upper surface of described body 1, the outer wall of described projection 4 contacts with the inwall of described hopper 2, good sealing effect.
The lower surface of described body 1 is extended with location convex tendon 5 downwards, in transportation, positions.
The utility model in use, magnetic obtains magnetic pressed compact after moulding press compacting, then magnetic pressed compact is put into the hopper 2 of body 1, when all hoppers 2 of body 1 are filled after magnetic green compact, carry out oil packing in the outside of body 1 by nylon again, remove wrapper through waiting after static pressure, from the interior taking-up magnetic of hopper 2 green compact of body 1, then be put in sintering box and can carry out sintering.
Adopt said structure splendid attire magnetic green compact, substituted Vacuum Package, can be recycled, saving resource, operates more convenient; And body adopts elastomeric material to make, material softness, can effectively avoid magnetic green compact in packing machine transportation, to occur the quality problems of unfilled corner and fracture, has ensured the quality of product.
Claims (3)
