Mold-pressing device

Abstract

A mold-pressing device including a seat body formed with a horizontal fissure at one end and a vertical chamber communicated with the fissure. A mold block is disposed in the chamber. One face of the mold block is disposed with a solid die, while the other face of the mold block is disposed with a channel passing through the mold block. A pressing lever is pivotally disposed in the channel of the mold block. A housing covers the seat body and is formed with a window for a pressing section of the pressing lever to extend therethrough. In use, a paper or a sheet is pushed into the fissure of the seat body and then the pressing section of the pressing lever is depressed, whereby a protuberance of the pressing lever is moved downward to force the mold block downward with the die punching the paper or the sheet placed in the fissure. Therefore, a product with a shape as that of the die is formed.

What is claimed is:  
     
       1. A mold-pressing device comprising: 
       a seat body formed with a horizontal fissure at one end and a vertical chamber, a bottom of the chamber being formed with an opening communicated with the fissure, a pair of opposite notches being formed on the periphery of the chamber, an insertion cavity being disposed in one notch opposite to the other notch, a bottom of the seat body being formed with a through hole communicated with the fissure opposite to the opening;  
       a mold block disposed on the seat body, one face of the mold block facing the fissure being disposed with a solid die, the other face of the mold block being disposed with a channel passing through the mold block;  
       a pressing lever disposed in the channel of the mold block, one end of the pressing lever being disposed with a pivot shaft for rotatably inserting in the insertion cavity of the seat body, whereby the pressing lever is pivotally disposed on the seat body, the other end of the pressing lever being disposed with an upward bent pressing section, the pressing lever being further formed with a protuberance extending in a direction reverse to that of the pressing section; and  
       at least one resilient member fitted under the mold block in the chamber of the seat body.  
     
     
       2. A mold-pressing device as claimed in  claim 1 , wherein an outward extension is disposed on rear side of the chamber of the seat body, the mold block being disposed with a projection for fitting in the extension, the resilient member being fitted under the projection between the bottom of the chamber and the mold block. 
     
     
       3. A mold-pressing device as claimed in  claim 1 , wherein a housing covers the seat body and is formed with a window, whereby the pressing section of the pressing lever extends through the window out of the housing. 
     
     
       4. A mold-pressing device as claimed in  claim 1 , wherein the resilient member is a spring. 
     
     
       5. A punch for punching a sheet of material, said punch comprising: 
       
         a body formed with a fissure for receiving the sheet of material, and a pivot shaft defining a pivot point;  
       
       
         a lever pivotably mounted about said pivot point of said pivot shaft;  
       
       
         a block positionable between said lever and said body, said block having a die moveable along a first axis, said block further comprising a channel configured to receive said lever; and  
       
       
         at least one resilient member adjacent to said die along a second axis spaced apart from said first axis, and disposed between said block and said body, wherein when said block is positioned between said lever and said body and when said lever is pivoted about said pivot point between a first position and a second position, said lever engages said block having said axially moveable die to punch the sheet of material.  
       
     
     
       6. The punch according to  claim 5 , wherein said at least one resilient member comprises first and second oppositely disposed springs adjacent to said die, said first spring disposed along said second axis and said second spring disposed along a third axis, said third axis spaced apart from said first and second axes.  
     
     
       7. The punch according to  claim 5 , wherein said fissure is substantially perpendicular to said first axis.  
     
     
       8. The punch according to  claim 7 , wherein said body has an opening which communicates with said fissure.  
     
     
       9. The punch according to  claim 8 , wherein said opening has a shape that corresponds to said die.  
     
     
       10. The punch according to  claim 7 , wherein said body has a pair of aligned openings which communicate with said fissure.  
     
     
       11. The punch according to  claim 5 , wherein said punch further comprises a housing which houses said block when positioned between said body and said lever.  
     
     
       12. The punch according to  claim 11 , wherein said lever extends through said housing.  
     
     
       13. The punch according to  claim 11 , wherein said housing provides an indication corresponding to a shape of said die.
