A kind of Capsules stoving process
Technical field
The present invention relates to Capsules tools technical field, specifically belong to a kind of Capsules stoving process.
Background technology
Capsules generally has mould to make, and is generally that mould is stained with glue, carries out drying, the demoulding after taking-up.Existing mould is all a large core rod the same as capsule, and core rod is solid.During oven dry, solid core rod absorbs heat comparatively greatly, and glue drying course is comparatively slow, affects production efficiency, and drying course temperature should not control simultaneously, easily occurs wabbler, affects product quality.In existing capsule drying course, be all that capsule is positioned in drying chamber, dry from outside to inside.In capsule drying course, have multiple stage, each phase temperature needs difference, controls bad, and just easily occur wabbler, when drying in this fashion, need slowly to regulate temperature, affect production efficiency, product quality cannot ensure.
Summary of the invention
The object of this invention is to provide a kind of Capsules stoving process, overcome the deficiencies in the prior art, mold simplicity of design, rational in infrastructure, hollow by making in empty capsule die, from inside to outside dry during oven dry, be convenient to bake out temperature and control, product there will not be wabbler, improves product quality.
The technical scheme that invention adopts is as follows:
A kind of Capsules stoving process, this described technique, comprises a kind of Capsules stoving process, and described mould is cylindrical, and die body outer surface has holddown groove, and inside is hollow structure, and upper end is hemispherical disc; Mould is positioned on mould bar, in each drying section of mould bar lower end, is equipped with controlled temperature cabinet, each drying section controlled temperature cabinet temperature, and require to arrange according to stoving process, controlled temperature cabinet is provided with multiple air vent, and air vent is corresponding with Kongxiang in mould bar mold.
Described air vent is provided with ventilation duct, and ventilation duct is inserted in mould, blows.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is hollow by making in empty capsule die, from inside to outside dries during oven dry, is convenient to bake out temperature and controls, mold can be reached rapidly required temperature, temperature on mold is more even, and product there will not be wabbler, improves product quality, improves production efficiency.
Detailed description of the invention
A kind of Capsules stoving process, this described technique, comprises a kind of Capsules stoving process, and described mould is cylindrical, and die body outer surface has holddown groove, and inside is hollow structure, and upper end is hemispherical disc; Mould is positioned on mould bar, in each drying section of mould bar lower end, be equipped with controlled temperature cabinet, each drying section controlled temperature cabinet temperature, require to arrange according to stoving process, controlled temperature cabinet is provided with multiple air vent, air vent is corresponding with Kongxiang in mould bar mold, air vent is provided with ventilation duct, and ventilation duct is inserted in mould, blows.So from inside to outside heating, drying, during oven dry, temperature is convenient to control, and product there will not be wabbler phenomenon.
