Water flows into the backwater main pipeline of underground.
Step 104: the nethike embrane of taking-up and the blank being put into forming machine lower die, the PLC controller passes through
Controlling forming machine pneumohydraulic pressure-cylinder drives forming machine movable plate along forming machine guiding axis downlink, molds with forming machine lower die.
Step 105: the PLC controller control clamping pressure completes hot extrusion baking molding, is taken through formed product
Between after, the PLC controller drives the forming machine movable plate along the sizing by controlling the forming machine pneumohydraulic pressure-cylinder
Machine guiding axis uplink takes out shaped article.
The type of existing same industry class is because without water slurry with for process unit, 4 electromagnetic valve switch whitewashing valve assemblies
Whitewashing cannot be voluntarily controlled for slurry program at regular time and quantity according to respective, cause concentration of slurry uneven, cause billet weight not
, product weight difference is big.Water slurry is added with after for process unit in the present invention, and 4 electromagnetic valve switch whitewashing valve assemblies are according to respectively
From voluntarily control whitewashing for slurry program at regular time and quantity, so that it is uniform to reach concentration of slurry, product weight equilibrium.Wherein, timing
It is quantitative to be set according to actual needs for slurry program.
The type of existing same industry class is completed in slip casting, and Starch Level can generate many bubbles, is inhaled very if opening negative pressure immediately
Empty butterfly valve pumps the pure water in slurry, and the surface of shaped article just has bubble to print stain, influences product appearance quality.In order to overcome
Drawbacks described above, the present invention wait 3-5 seconds after the slurries in slurries funnel reach set volume amount, are then turned on negative pressure and inhale vacuum
Butterfly valve and discharging valve, siphon away pure water, can eliminate foam, it is ensured that product appearance quality.
In addition, do not close negative pressure immediately after the pure water in slurries funnel siphons away and inhale vacuum butterfly valve and discharging valve, but will
After molding machine upper mold uplink, machine upper mold to be formed and net mould, slurry base are detached from, turn off negative pressure and inhale vacuum butterfly valve and discharging valve, from
And ensure in molding machine upper mold uplink, slurry base is firmly adsorbed on net mould, is not formed machine upper mold and is adhered and pulls, it is ensured that product
Quality.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
Used herein a specific example illustrates the principle and implementation of the invention, and above embodiments are said
It is bright to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, foundation
Thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification is not
It is interpreted as limitation of the present invention.
