Description

It is used to prepare the mold of the radiator with length cooling fin
Technical field
The present invention relates to the preparation fields of cooling fin, and the heat dissipation with length cooling fin is used to prepare more particularly to a kind of The mold of device.
Background technology
Radiator refers to that the heat for generating machinery or other utensils during the work time is shifted in time to avoid it is influenced The device or instrument of normal work.In actual production, needs to produce mutually to be fastened by two kinds of inconsistent cooling fins of length and formed Radiator.
There are two ways to preparing the radiator in industry at present:When utilize two kinds of molds, by long cooling fin and it is short dissipate Backing is combined after punch process again respectively;Second is that a kind of mold will be utilized to produce long and short two kinds of cooling fins simultaneously, but it is short Cooling fin needs to be attached using even tablet, and company's tablet is connection cooling fin and material strip in traditional moulds technology , to ensure size and craftsmanship, increases intensity and design, be unwanted in the product, finally need to cut off.But institute Long cooling fin is first produced in the existing mold stated, regeneration output is connected with the short cooling fin of tablet, and right on mold Even the connecting portion of tablet and cooling fin is thrust in advance, is finally had no progeny and long cooling fin fastens by manually breaking company's tablet Radiator needed for being formed.
Above two methods are both needed to carry out secondary operation, and manufacture craft is cumbersome, manually with time cost height, can not ensure The precision and qualification rate of product.
Invention content
