Detailed description of the invention
Embodiment 1
As in Figure 2-4, present invention is disclosed a kind of stack pneumatics mould, including punching mechanism, ejecting mechanism and resetting-mechanism. Described punching mechanism includes die and is arranged on the drift 7 below die, and described die includes interior die 1 and is socketed the outer die 2 being arranged on around interior die 1. De-feed ring 3 that described ejecting mechanism includes being socketed on interior die 1, it is sheathed on interior die 1 and the knock-pin 4 that is connected with de-feed ring 3 upper end. Described resetting-mechanism includes the spring 5 being arranged at above knock-pin 4 and the release link 6 being arranged at below knock-pin 4. Described spring 5 and release link 6 are arranged on the same side of knock-pin 4.
Described interior die 1 lower end is a cylindrical structure, and the diameter of described cylindrical structure is equal with the female internal diameter D1 at product 8 center 82.Described outer die 2 is socketed in around interior die, but there is certain interval between the two, described gap length machine with product 8 after sidewall 81 thickness equal. The lower edge position of described interior die and outer die is provided with a circle and enters the chamfering 9 of mould for direct product.
Described drift 7 is arranged on the lower section of interior die 1 and outer die 2, and the head of drift 7 is planar structure, for support product 8. The diameter of described drift is suitable with product outer diameter D 2.
Described drift 7 and die are not in contact with each other under device holding state, and are provided with punching press reserved area between the two, the size of described punching press reserved area complete with Product processing after bottom thickness equal.
Described de-feed ring 3 is a cylindrical structure, is socketed on interior die 1. The circle wall thickness of described de-feed ring 3 is equal with the gap length between interior die 1 with outer die 2.
One end of described knock-pin 4 is provided with a slotted eye, and the upper end of described interior die 1 is placed in described slotted eye, and the other end of described knock-pin 4 is arranged below a release link 6 that described knock-pin 4 can be promoted to move.
Described spring 5 is arranged on above knock-pin 4 and is close to the surface of knock-pin 4, and described spring 5 can carry out longitudinal extension. Knock-pin 4 in position set by spring is arranged below release link 6. Described release link 6 is movable structure, and knock-pin 4 can be driven together to move upward when release link 6 moves upward, and knock-pin 4 upwards compresses spring 5, and drives retainer circle 3 upwards to reset.
The work process of the present invention described briefly below and processing method: before pneumatics molding, described release link 6 moves upward, thus by described knock-pin 4 upwards jack-up, knock-pin 4 moves upward and compresses spring 5, and knock-pin 4 band is automatically connected in de-feed ring 3 below and upwards completes to reset.
During pneumatics molding, the product 8 after preamble PROCESS FOR TREATMENT being placed on drift 7, along with moving upward of drift 7, promoting product 8 to enter in the gap of interior die 1 and the formation of outer die 2, thus completing the molding of product 8 sidewall 81.
After pneumatics molding, described drift 7 resets downwards, subsequently, release link 6 moves downward, and makes spring 5 expansion reset, and promotes described knock-pin 4 to move down, drive described de-feed ring 3 to move downward, and will complete product 8 ejection die of pneumatics molding, complete the de-material of product 8.
The present invention by adding one stamping procedure after traditional molding procedure, it is achieved that the laminating completely of the product sidewall materials at two layers that tradition processing cannot realize. Simultaneously as product material is the aluminum of annealed state, this material is very soft and has certain viscosity, and the spring force that therefore this device ejects can't cause deformation of products, thus ensure that the quality of product.
Embodiment 2
As it is shown in figure 5, a kind of stack pneumatics mould of the present invention can also have another preferred embodiment. In the present embodiment, the interior die of mould is made up of indent mould body 11 and the indent set 12 being socketed on described indent set body 11, and the outer die of mould is made up of outer die body 21 and the outer recessed circle 22 that is socketed on described outer die body 21. Described inside and outside die is dismountable socket joint type structure. Described indent set 12 arranges reeded cylinder for centre, and the inwall of described indent set 12 is provided with a circle Magnet 10, and described indent set 12 can be socketed on indent mould body 11 layer by layer by described Magnet 10. Owing to indent mould body 11 being socketed with several indents set 12, so the Magnet 10 inside adjacent two indents set 12 adopts the structure being crisscross arranged up and down, it is to avoid all Magnet 10 are arranged on and that cause in same level make indent membrane module arrange unstable phenomenon because Magnet 10 is mutually exclusive.
The bottom of described outer recessed circle 22 is provided with a bottom surface extended laterally, the skew dislocation that outer die assembly occurs because of bottom unbalance stress can be effectively prevented when drift 7 upwards punching press by arranging of described bottom surface, further increase the stability of mould, it is ensured that the quality of processed product. The arranged outside of described outer recessed circle 22 top circle body has the circle Magnet 10 for connecting equally, and described outer recessed circle 22 can be socketed on outer die body 21 layer by layer by described Magnet 10. Identical with the position that Magnet 10 in indent membrane module is arranged, the Magnet 10 on the outer recessed circle of adjacent two is also adopted by being crisscross arranged up and down to ensure the stability of assembly.
The de-feed ring 3 that described de-feed ring assembly includes several different-thickness different-diameters forms, and described de-feed ring 3 can carry out corresponding replacement according to the spacing size that interior die is different with outer die, to meet the de-material operation of different size converted products. And because described indent membrane module and outer die assembly have all applied to Magnet 10 and be attached, in order to avoid the impact on mould processing therefore brought, described de-feed ring 3 should adopt and will not be undertaken manufacturing processing by the metal of magnet adsorption, can adopt aluminum alloy materials manufacture in the present embodiment. Due to the aluminum that material is annealed state that this mould is processed, so the magnetic that this mould adopts connects the quality of product can't be produced impact.
The present embodiment 2 and embodiment 1 are distinctive in that in the present embodiment interior die relatively-stationary in original device and outer die to be improved, interior die is changed into and is collectively constituted with indent set 12 by indent mould body 11, outer die is changed into and is collectively constituted with outer recessed circle 22 by outer die body 21, and be provided with matched de-feed ring, thus add regulatory function on the basis of original device. Can pass through to regulate the size of the Level Change punching press reserved area of drift 7 upwards punching press in process of production, subsequently by selecting the die overlapped with processed product matching size and de-feed ring to complete the processing of the product to different inner diameters, various outer diameter and different-thickness. Thus adding the range of application of this device, improve the practicality of device.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, all falls within protection scope of the present invention.
