Abstract
The utility model relates to a punching mould for overcoming the product expansion and contraction, belonging to the field of printed circuit boards. The punching mould for overcoming the product expansion and contraction comprises an upper mould fixing plate, a lower mould fixing plate, a pressing plate, punches, jacking blocks, springs and concave template locating nails, wherein the punches are arranged on the upper mould fixing plate, the pressing plate is arranged between the punches and is connected to the upper mould fixing plate through a spring, the pressing plate is provided with an upper mould avoiding place for overcoming expansion and contraction, the jacking blocks are fixed on the lower mould fixing plate, the jacking blocks are connected to the lower mould fixing plate through the springs, concave mould plates are arranged between the jacking blocks and are provided with pits, and the locating nails are arranged on the lower mould fixing plate. The punching mould for overcoming the product expansion and contraction has the advantages of increasing processing efficiency, lowering labor cost and ensuring punching quality.
Description
Technical field
The punching die that the utility model overcomes product breathing belongs to the printed circuit board field.
Background technology
Flexible printed-circuit board is widely used in each electronic product because of its light, thin characteristics, such as communication class, automotive electronics, Medical Instruments and aero-space instrument etc.Because flexible printed board in process of production, is subject to various various factors impacts, causes product breathing.And some product breathing is wayward.So just cause when becoming monolithic with mould punching, the location goes wrong.Phenomenon can appear pullling.Mould has been done little affects production efficiency, has done greatly the location and has been forbidden, and the product design of going out is overproof to wire pitch.
The utility model content
The purpose of this utility model is to utilize the development of new technology, overcomes in process of production uppity product breathing problem of product, and punching goes out qualified product.
The purpose of this utility model reaches by following measures, overcome the punching die of product breathing by upper mould fixed plate, the counterdie fixed head, holding pad, drift, ejection block, spring, concave template, locating pin forms, drift is arranged on the upper mould fixed plate, holding pad is arranged between the drift, holding pad is connected on the upper mould fixed plate by spring, holding pad is designed with the patrix that overcomes breathing and keeps away the position, ejection block on the counterdie fixed head, ejection block is connected on the counterdie fixed head by spring, concave template is arranged between the ejection block, concave template top is concave design, on the lower fixed form locating pin is arranged.
The utility model overcomes the punching die of product breathing, and the two or more location spacing with punching during design inside contracts 3-5mm, forms the patrix that overcomes breathing and keeps away the position.
ThisThe punching die upper and lower mould needs the empty avoiding of product arched part is processed, and the empty avoiding position must be smooth, can not cause product in the punching process to weigh wounded.
The punching die that the utility model overcomes product breathing can improve working (machining) efficiency, reduces labor cost, guarantees the punching quality.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: upper mould fixed plate 1, counterdie fixed head 2, holding pad 3, drift 4, ejection block 5, spring 6, concave template 7, locating pin 8.
Shown in accompanying drawing 1, the utility model is made of upper mould fixed plate 1, counterdie fixed head 2, holding pad 3, drift 4, ejection block 5, spring 6, concave template 7, locating pin 8, drift 4 is arranged on the upper mould fixed plate 1, holding pad 3 is arranged between the drift 4, holding pad 3 is connected on the upper mould fixed plate 1 by spring 6, holding pad 3 is designed with the patrix that overcomes breathing and keeps away the position, ejection block 5 on the counterdie fixed head 2, ejection block 5 is connected on the counterdie fixed head 2 by spring 6, concave template 7 is arranged between the ejection block 5, concave template 7 tops are concave design, on the lower fixed form 2 locating pin 8 are arranged.
During use, the patrix that customer service on concave template and holding pad contracting is risen is kept away the position and has been formed certain space, and the scope that can have sufficient space to bear product to be rushed because the contracting that causes during punching press is risen solves the orientation problem that the product contracting is risen and caused.
