Hot-pressing sizing device

Abstract

The invention relates to a hot-pressing sizing device. The hot-pressing sizing device comprises a base, a first heat insulation piece, a second heat insulation piece, a heating lower die, a cooling lower die, a pressing base, a third heat insulation piece, a fourth heat insulation piece, a heating upper die, a cooling upper die, a plurality of guiding columns and buffer springs, wherein the heating lower die and the cooling lower die are arranged in the first heat insulation piece and the second heat insulation piece in an inlaid mode respectively; the heating upper die is arranged in the third heat insulation piece in an inlaid mode; the cooling upper die is arranged in the fourth heat insulation piece in an inlaid mode; the multiple guiding columns are fixed to the pressing base and sleeved with the buffer springs. Heating rods are arranged in the heating lower die and / or the heating upper die. The cooling lower die and / or the cooling upper die are provided with water inlets, water outlets and pipelines which are communicated with the water inlets and the water outlets. A cell phone middle frame is clamped between the heating lower die and the heating upper die, the cell phone middle frame is deformed at a preset high temperature through the heating rods, and the flatness is restored. Then the cell phone middle frame which is affected at the preset high temperature is taken out and clamped between the cooling lower die and the cooling upper die, and the cell phone middle frame can be cooled and sized rapidly by pouring circulating water flow. According to the hot-pressing sizing device, the sizing effect is good, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile phone processing and manufacturing, in particular to a hot-press shaping device. Background technique [0002] In recent years, with the popularization of smart phones, users have increasingly favored smart phones with large screens. However, the larger the middle frame of the mobile phone, the easier it is to deform after production processes such as die-casting, stamping, drilling, and milling, resulting in flatness. degree of deterioration. After the mobile phone screen is installed on the middle frame of the mobile phone with poor flatness, water ripples and other undesirable phenomena often appear on the mobile phone screen, and the gap between the mobile phone screen and the mobile phone middle frame increases, and dust is easy to enter, which affects the appearance of the smart phone . Traditionally, for the middle frame of a mobile phone with poor flatness, manual folding is used, and aft...
