The utility model has the advantages that: the problem of deformation of the sintered product is effectively solved, the product quality is ensured, the operation is convenient and rapid, and the production efficiency is high; can be widely popularized to the shaping production of other round open type products of my department.
Description
Technical Field
The utility model relates to a plastic mould's field, concretely relates to internal diameter plastic mould structure of circular open metal injection moulding product.
Background
I produced various round open type products by a metal injection molding process, and the products can generate slight necking after sintering, so that the product is deformed and the size of the product is influenced. If adopt simple and easy plastic tool to beat the mode that realizes the product plastic through the operation workman is manual, also can solve this type of product deformation problem to a certain extent, nevertheless manual beat very serious to the damage of product, the yields is low, and production efficiency is low, and the practicality is not strong, and has increased workman's work burden, and the effect is not ideal.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide an internal diameter plastic mould structure of circular open metal injection moulding product, it is high to have production efficiency, and convenient operation effectively solves the product deformation problem.
The purpose of the utility model is accomplished through following technical scheme: the inner diameter shaping die structure of the round open type metal injection molding product mainly comprises an upper die and a lower die, wherein the upper die and the lower die are respectively clamped and fixed on a hydraulic machine; a draw hook is arranged on the upper die corresponding to the draw hook groove, a pressing block is also arranged on the upper die, and the pressing block is positioned right above the shaping needle; pressing down by a hydraulic machine to enable the upper die and the lower die to be closed, so as to realize the compaction and shaping of the product; the T-shaped groove shaping block is pulled upwards through the draw hook, and the spring pushes the T-shaped groove shaping block upwards to push out a product to realize demoulding.
The utility model has the advantages that: the problem of deformation of the sintered product is effectively solved, the product quality is ensured, the operation is convenient and rapid, and the production efficiency is high; can be widely popularized to the shaping production of other round open type products of my department.

Description of reference numerals: the device comprises an upper die 1, a lower die 2, a hydraulic machine 3, a T-shaped groove shaping block 4, a T-shaped groove 5, a spring 6, a drag hook groove 7, a shaping needle 8, a product 9, a pressing block 10 and a drag hook 11.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the inner diameter shaping die structure of the circular open type metal injection molding product mainly comprises an upper die 1 and a lower die 2, wherein the upper die 1 and the lower die 2 are respectively clamped and fixed on a hydraulic machine 3, a T-shaped groove shaping block 4 with a T-shaped groove 5 is arranged on the lower die 2 through a spring 6, a shaping needle 8 for sleeving a product 9 is arranged in the T-shaped groove 5, and a draw hook groove 7 is also formed in the T-shaped groove shaping block 4; a draw hook 11 is arranged on the upper die 1 corresponding to the draw hook groove 7, a pressing block 10 is also arranged on the upper die 1, and the pressing block 10 is positioned right above the shaping needle 8; the upper die 1 and the lower die 2 are closed by pressing down through a hydraulic machine 3, so that the product 9 is compacted and shaped; the T-shaped groove shaping block 3 is pulled upwards through the draw hook 6, and meanwhile, the spring 4 pushes the T-shaped groove shaping block 3 upwards to push out a product 9 to realize demoulding.
The utility model discloses a working process: during production, the hydraulic machine 3 is controlled to move upwards, the upper die 1 and the lower die 2 are opened, the T-shaped groove shaping block 3 bounces upwards under the action of the spring 6, and the T-shaped groove 5 is exposed; then the product 9 is sleeved on the shaping needle 8 according to the direction, the upper die 1 and the lower die 2 are closed by pressing down through the hydraulic machine 3, at the moment, the product 9 is completely sleeved on the shaping needle 8 and is simultaneously extruded by the T-groove shaping blocks 3 on the two sides of the shaping needle, namely, the interior of the product 9 is propped by the shaping needle 8, the periphery is extruded by the T-groove shaping blocks 3, and the upper end is pressed by the pressing block 10, so that the product deformation is corrected to reach the required size; after the pressing action is finished, the hydraulic machine 3 moves upwards to enable the upper die 1 and the lower die 2 to be opened again, and the T-shaped groove shaping block 3 moves upwards to push out the product 9 under the acting force of the pull hook 11 and the spring 6 to realize demoulding.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
