Description
Technical field:
This utility model relates to technical field of mold, refers in particular to the powder metallurgy pressing die of metallic mobile phone shell.
Background technology:
At present, when complicated formed product suppressed by the mould of powder metallurgy, owing to its internal temperature is higher, its stress is more concentrated, and when causing depanning, frictional force is bigger, poor stability, affecting the mechanical performance of product to be processed, product is easily generated crackle, poor bonding strength, product surface is rougher, and mould easily blocks the most active.
Utility model content:
The purpose of this utility model is aiming at the deficiency of prior art existence and provides the powder metallurgy pressing die of the metallic mobile phone shell of a kind of simple in construction, good cooling effect, raising product mechanical performance and stability.
To achieve these goals, the technical solution adopted in the utility model is: the powder metallurgy pressing die of metallic mobile phone shell, include bottom punch, former and upper punch, die cavity is offered on former, bottom punch is arranged on the bottom in die cavity, and bottom punch upper surface is provided with support plate, and upper punch is vertically slidably connected in die cavity, offering spiral surrounding spiral cooling tube road outside die cavity in former, former offers ease powder groove on the sidewall in the middle part of die cavity.
The mould top perimeter of described former offers internal spline, and upper punch is convexly equipped with the external tooth coordinated with internal spline on the outer surface at top, and external tooth is vertically slidably connected in internal spline.
Described bottom punch upper surface is convex is provided with multiple positioning boss, offers multiple and positioning boss corresponding matching detent bottom support plate.
Described bottom punch, former and upper punch are circular configuration.
This utility model has the beneficial effects that: the powder metallurgy pressing die of the metallic mobile phone shell that this utility model provides, include bottom punch, former and upper punch, die cavity is offered on former, bottom punch is arranged on the bottom in die cavity, bottom punch upper surface is provided with support plate, and upper punch is vertically slidably connected in die cavity, and this utility model utilizes support plate to carry product, product after compacting can be transferred in agglomerating plant together by support plate, and transfer is convenient；This utility model former offers spiral surrounding spiral cooling tube road outside die cavity, it is passed through cold water in spiral cooling tube road, effectively reduce temperature during product depanning, reduce stress to concentrate, reduce frictional force during depanning, product pressure fluctuation range reduces, and improves the mechanical stability of product, extends the mold use life-span；And offer ease powder groove on the sidewall that former is in the middle part of die cavity, the product that will originally need more drift to suppress, by the way of with ease powder, available minimum drift compacting, reduce the manufacturing cost of mould, reduce the Making mold time, improve mode transfer speed, improve dimensional accuracy and the production efficiency of product.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is further described, as shown in Fig. 1～2, this utility model includes bottom punch 1, former 2 and upper punch 3, offering die cavity 21 on former 2, bottom punch 1 is arranged on the bottom in die cavity 21, and bottom punch 1 upper surface is provided with support plate 4, upper punch 3 is vertically slidably connected in die cavity 21, this utility model utilizes support plate 4 to carry product, and the product after compacting can be transferred in agglomerating plant together by support plate 4, and transfer is convenient；This utility model former 2 offers spiral surrounding spiral cooling tube road 22 outside die cavity 21, it is passed through cold water in spiral cooling tube road 22, effectively reduce temperature during product depanning, reduce stress to concentrate, reduce frictional force during depanning, product pressure fluctuation range reduces, and improves the mechanical stability of product, extends the mold use life-span；And offer ease powder groove 23 on the sidewall that former 2 is in the middle part of die cavity 21, the product that will originally need more drift to suppress, by the way of with ease powder, available minimum drift compacting, reduce the manufacturing cost of mould, reduce the Making mold time, improve mode transfer speed, improve dimensional accuracy and the production efficiency of product.
The mould top perimeter of former 2 offers internal spline 24, upper punch 3 is convexly equipped with the external tooth 31 coordinated with internal spline 24 on the outer surface at top, external tooth 31 is vertically slidably connected in internal spline 24, good positioning action and guide effect can be played between internal spline 24 and external tooth 31, improve the precision of product.
Bottom punch 1 upper surface is convex is provided with multiple positioning boss 11, offers multiple and positioning boss 11 corresponding matching detent 41 bottom support plate 4, and accurate positioning, Product Precision is higher.Bottom punch 1, former 2 and upper punch 3 are circular configuration.
Certainly, the above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all it is included in this utility model patent claim.
