Description

The pressue device of air hermetic continuous hot-press molding machine

Technical field

The utility model provides a kind of heat pressing forming device, and especially a kind of air hermetic being suitable for manufacturing stereo product connects The pressue device of continuous heat pressing forming device.

Background technology

Hot-forming is a kind of processing method of high molecular material, will mainly have certain thickness material and is placed in mold, Heating mould or environment are made material softening and are covered in die surface, then extruded with machine, after cooling stage cures, just Hot-forming product can be obtained.

Hot-forming material, by taking glass as an example, glass is because have the characteristic of higher light transmission, therefore display device is (such as The electronic products such as mobile phone, wrist-watch) multiselect its shell as form part.The visible handheld electric products surface of monarch is typically provided with glass Glass shell, to protect the display module of interiors of products.Glass shell is all largely the shape of tablet at present, so being produced in electronics The upper surface of product can form seam.Furthermore since the periphery of electronic product must retain the mechanism section of one fixed width, to Flat glass is held, therefore the top surface of electronic product also can not be just utilized completely.Therefore, three-dimensional or bend glass is gradually Being employed on the glass shell of electronic product gradually.

Flat glass shell is easier to manufacture, and the manufacture of the glass shell with three-dimensional shape is then more not easy.Currently, tool There is the manufacture of the glass shell of three-dimensional shape usually there are two types of method：The first is：The flat glass unit of multi-disc is manufactured, then The glass shell with three-dimensional shape is formed by way of pasting edge.It is for second：Manufacture certain thickness cuboid glass Glass, then in grinding multiple on the cuboid glass to be formed with multi-sided three-dimensional contouring.However, above-mentioned two method is equal It takes time and effort, speed of production is very slow.Generally, due to which glass material is a tabular, if to produce one has moulding Glass, flat glass material is set to a upper mould piece and once between module by the preferable practice, then heats upper mold Part, lower module and glass material, so that glass material softens.When above-mentioned glass material softening, upper mould piece and lower module Mould assembling action can be carried out, so that upper mould piece moulds the shape of glass material along a molding direction jointly with lower module, so as to life Produce corresponding moulded glass.TaiWan, China patent announcement M452174 " for manufacturing the former of moulded glass " (bulletin Day is on May 01st, 2013), it includes have a parent form mold members, one first male mold members, one second male mold members, one Supporting post-rod and a compression bar.The first male mold members are set in a manner of openable and closable in the parent form mold members, this second Male mold members are set between the parent form mold members and the first male mold members.The supporting post-rod is arranged in the parent form mold Part, the supporting post-rod are used for ejection in the second male mold members, so as to supporting the second male mold members and first male A moulded glass is clamped in mold members jointly.The compression bar is set to the side of the first male mold members, which is pressed under being used for The first male mold members, so that the first male mold members parent form mold members opposite with the second male mold members are moved to One die-closed position, so as to being molded the moulded glass.

Applicant is previously proposed " the continuously shaped dress of air hermetic model solid glass of TaiWan, China the M536234th being approved Set ", it is closed, stove mainly by furnace body for the brand-new design of apparatus for continuous formation of model solid glass product design Two ends are equipped with exchange system outside body, and furnace interior is equipped with air-tight cavity；Exchange system, is set to two end of furnace body, and two end of furnace body exchanges Outer feed track is equipped between system, each exchange system includes the outer gas set on the interior gas-tight door of furnace body side and set on outer feed track side Mi Men forms airtight space, and support plate is pushed into or is removed furnace body equipped with gearshift between interior gas-tight door and outer gas-tight door；It is airtight Chamber is set to furnace interior, includes air tight housing, and there is interior feed track, two end of interior feed track connection furnace body to hand in air tight housing Gas-tight door in system is changed, and is equipped with sliding rail, using the track moved as support plate, which is air hermetic, and imports protection gas Body, and have heating zone according to processing procedure differentiation), high-temperature molding area and cooling zone, be equipped in heating zone and high-temperature molding area at least one layer of Insulation layer, and insulation layer center forms thermal field, the heating element regarding fabrication procedures required temperature is equipped in thermal field, cooling zone has Cooling device, high-pressure molding area are equipped with compression system；Outer feed track connects two end exchange system of furnace body；Compression system, mainly by Cylinder pressure, pressuring shaft and pressured column are constituted；Thus configured the utility model, plate glass to be formed are placed in mould surface, Mold is then placed on support plate, and support plate enters air-tight cavity through exchange system, the high temperature of preheating and high-temperature molding area through heating zone, Make Glass Transition in mould, and be molded by the pressurization of compression system, then after the cooling of cooling zone, stove is sent out through exchange system The effect of outside body, then demoulding, also capable of really reaching continuous, high efficiency and high-quality molding model solid glass.

As previously mentioned, existing compression system, is mainly made of cylinder pressure, pressuring shaft and pressured column, since cylinder pressure can not essence Speed that true control pressured column is applied on hot pressing die, intensity of pressure size and it is accurately positioned shift length, and compression train System applies pressure to the centre of opposite hot pressing die with single compression system set on the center of every group of hot pressing die.This for When hot pressing model solid glass its size is smaller, the flatness of model solid glass is still maintained, but for larger-size Model solid glass product (such as tablet computer, notebook computer and vehicle-mounted ...), because compression system applies pressure and concentrates on The center of hot pressing die easily causes the situation that model solid glass product quadrangle generates the out-of-flatnesses such as warpage, crooked, keeps model vertical The hot-forming yield of body glass is extremely low.This is that the existing prior art has maximum defect, this missing is into industry urgently gram The problem of clothes.
