Description
Technical field
The utility model is related to hardware stamping equipment technical fields, and in particular to a kind of secondary drawing for monitor shell
Stretch mold.
Background technology
At present, the succeeding stretch operation for monitor shell in the market is stretched using punching machine, on the one hand, by
It is fast in punching machine speed, it easily leads to monitor shell and splits, scraps, fraction defective is high；On the other hand, due to being stretched using punching machine to drawing
The R angles requirement of product bottom is higher before stretching, and therefore, needs to carry out R angles integer using mold before succeeding stretch, then carries out two
Secondary stretching, efficiency are low.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of succeeding stretch mold for monitor shell.
Technical solutions of the utility model are as follows：
A kind of succeeding stretch mold for monitor shell, including upper die component, lower mold assemblies, upper mold hydraulic press and under
Moulding oil press, the upper die component are followed successively by upper mold seat, upper padding plate and stretch cavity plate from top to bottom, the interior top for stretching cavity plate
Portion is equipped with interior de- plate, and the interior de- plate is movably arranged at by spring guide pillar on upper mold seat, and the lower mold assemblies include internal component
With the external module being looped around on the outside of internal component, wherein internal component is followed successively by punching press punch-pin, punching press punch-pin pad from top to bottom
Plate, die holder, external module are followed successively by blank holder, blank holder cushion block and lower die mandril, the top surface of the blank holder from top to bottom
The slightly above top surface of punching press punch-pin, the blank holder is with the appearance profile that punching press punch-pin surrounds with monitor shell through one-off drawing
Semi-finished product match, the punching press punch-pin be located at stretch cavity plate underface, the bottom profile of the interior de- plate and punching press are convex
The top profile of mould matches, the top profile of the punching press punch-pin and the bottom profile of semi-finished product of the monitor through succeeding stretch
Consistent, for upper mold seat to be driven to move downward, the lower die hydraulic press is used to drive lower die mandril band the upper mold hydraulic press
Dynamic pressure flange moves downward.
The beneficial effects of the utility model are：By the mould structure design and upper die component of this succeeding stretch under
Membrane module all using hydraulic press as power source, pressure-plate-force uniformly, stablize, obtain the qualification rate height of product, reach more than 95%,
It is efficient and without to the R angles progress integer of one-off drawing semi-finished product, can directly carry out succeeding stretch in advance.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Refering to Fig. 1, a kind of succeeding stretch mold for monitor shell, including upper die component, lower mold assemblies, upper moulding oil
Press and lower die hydraulic press, the upper die component are followed successively by upper mold seat 2, upper padding plate 4 and stretch cavity plate 5, the drawing from top to bottom
The inner top for stretching cavity plate 5 is equipped with interior de- plate 1, and the interior de- plate 1 is movably arranged at by spring guide pillar on upper mold seat 2, the lower die
Component includes internal component and the external module being looped around on the outside of internal component, and wherein internal component is followed successively by punching press from top to bottom
Punch-pin 7, punching press convex mould pad 10, die holder 12, external module are followed successively by blank holder 8, blank holder cushion block 9 and lower die from top to bottom
Mandril 11, the top surface of the blank holder 8 are slightly above the top surface of punching press punch-pin 7, and the blank holder 8 surrounds outer with punching press punch-pin 7
Shape profile matches with semi-finished product 6 of the monitor shell through one-off drawing, the punching press punch-pin 7 be located at stretch cavity plate 5 just under
Side, the bottom profile and the top profile of punching press punch-pin 7 of the interior de- plate 1 match, the top profile of the punching press punch-pin 7 and
The bottom profile of semi-finished product of the monitor through succeeding stretch is consistent, the upper mold hydraulic press for drive entire upper die component to
Lower movement, the lower die hydraulic press are used to drive lower die mandril 11 that blank holder 8 is driven to move downward.
During operation, semi-finished product of the monitor shell through one-off drawing 6 are covered on blank holder 8 first, then in startup
Moulding oil press, upper mold seat 2 move downward under the driving of upper mold hydraulic press, when it moves to the position being in contact with blank holder 8
When, lower die hydraulic press is started to work, and is driven and moved under 8 phase of blank holder, and punching press punch-pin 7 is transported upwards compared with blank holder 8 at this time
It is dynamic, and the semi-finished product of one-off drawing is driven to be moved into stretching cavity plate 5, upper mold hydraulic press and lower die hydraulic press work on, directly
To cavity plate 5 and the complete molding of punching press punch-pin 7 is stretched, succeeding stretch is completed, and is then that can obtain through secondary drawing stretching in cavity plate 5
The semi-finished product 3 stretched all are made by the mould structure design and upper die component and lower mold assemblies of this succeeding stretch using hydraulic press
For power source, pressure-plate-force is uniform, stablizes, and obtains the qualification rate height of product, reaches more than 95%, and without in advance to one-off drawing
The R angles of semi-finished product carry out integer, can directly carry out succeeding stretch, efficient.
Above-mentioned accompanying drawings and embodiments are merely to illustrate the utility model, and any technical field those of ordinary skill is to it
This technical change is made in suitably changing or modifying or use other flower pattern instead for being done, and all should be regarded as not departing from this practicality newly
Type patent category.
