Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-3, the present embodiment provides a mold structure for improving deformation of a side wall oil filler a surface, which includes an upper mold base 1 and a lower mold base 2, wherein a shaping knife block 3 is installed in the middle of the upper mold base 1, a pre-pressing spring 9 is arranged in the middle of the shaping knife block 3, and the shaping knife block 3 is protected by the pre-pressing spring 9 in a buffering manner; press core 4 is installed to 1 side of upper die base, press core 4 comprises big press core 5 and little press core 6, little press core 6 sets up in the 5 outsides of big press core, 5 fixed connection of big press core are on upper die base 1, be equipped with spring mount 7 on big press core 5 and the little press core 6 through sliding block sliding connection upper die base 1, be equipped with elastic component 8 on the spring mount 7, elastic component 8 adopts nitrogen spring, little press core 6 passes through elastic component 8 and installs on upper die base 1, set up little press core 6 alone, can adjust alone the pressure of little press core, be convenient for follow-up debugging increases pressure capacity and pressure. The stroke of little pressure core 6 is greater than the stroke of big pressure core 5, when compressing tightly the panel veneer, little pressure core 6 is suppressed with the panel veneer contact earlier, along with the continuation of upper die base 1 moves down, little pressure core 6 compresses through elastic component 8, big pressure core 5 moves down along with upper die base 1, stopper 10 slides in spacing groove 11, thereby make little pressure core 6 flush with big pressure core 5 lower extreme, big pressure core 5 suppresses the panel veneer with little pressure core 6 jointly, improve and press the material effect, little pressure core 6 die face width is 30mm, be convenient for compress tightly the panel veneer in advance fast.
