Description
Technical field
The utility model relates to mold cavity structure, especially a kind of paper mould paper kettle formation mould.
Background technology
At present, paper mould paper kettle formation mould normally forms a closed die cavity by upper and lower two moulds, the air chamber of upper and lower die cavity all needs to connect compressed air and vacuum, time shaping, mould immerses in paper pulp, vacuum valve is opened filtering means dehydration and is formed paper kettle consistent with mold cavity shapes and to wet base, when wet base takes out from mould, and upper/lower die separation, wet base is vacuumized by patrix and produces negative pressure and take up and be separated with counterdie, and then patrix passes into the compressed air paper kettle that blows off and wets base on splicing plate.Because upper lower chamber is independently, this makes the opening of die cavity not to be arranged on minimum point, thus produces defect in production process: 1, need to pass into compressed air when wet base transfer, wet uncoated paper kettle is easily blown flat.2, the sordid water of row in patrix air chamber is taken out of in air blowing process, and the moisture of wet base is increased and moisture inequality, and time dry, energy consumption increases and deformation of products amount increases, and the serious paper kettle that also can wash out wets base.3, the opening of die cavity is opened obliquely, causes remaining slurry in forming process not discharge and makes paper kettle wall unevenness even.4, required molding forming machine pipeline and control more complicated.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, a kind of paper mould paper kettle formation mould, comprise patrix 1 and counterdie 2, the die joint of described patrix 1 and counterdie 2 is provided with upper impression 11 and the lower impressions 21 of indent, the inside of described upper impression 11 and lower impressions 21 is respectively equipped with upper chamber 12 and lower chamber 22, and described upper impression 11 and the inwall of lower impressions 21 are provided with the spaced pore (scheming not shown) be communicated with lower chamber 22 with corresponding upper chamber 12; Described patrix 1 with the die joint of counterdie 2 is also provided be communicated with interface 13 with under be communicated with interface 23, described upper connection interface 13 with under be communicated with interface 23 and be communicated with lower chamber 22 with upper chamber 12 respectively; After described patrix 1 and the 2-in-1 mould of counterdie, described upper connection interface 13 with under be communicated with interface 23 and seal docking and formed and be communicated with air flue 3.
Compared with prior art, because upper chamber 12 is connected by being communicated with interface 13,23 up and down with lower chamber 22, lower chamber 12,22 is communicated with as a whole, when vacuum dehydration, water enters lower chamber 22 from the water in upper chamber 12 through being communicated with interface, and discharges from lower chamber 22.This design eliminates compressed air interface on patrix 1 and vacuum interface, and experimentally lower chamber 12,22 is communicated with as a whole, thus improves the problem of the high and uneven thickness of moisture of the impeded drainage of upper chamber, wet embryo, enhances productivity.
The die joint of counterdie 2 is provided with high portion 24 and lower curtate 25, described high portion 24 is formed slopely bending 26 shape of indent to lower curtate 25, described lower impressions 21 is arranged along the trend of the indent bending 26 of the die joint of described counterdie 2, and the front end 27 of counterdie 2 is run through in the lower end of described lower impressions 21, form lower mode cavity opening 271; The die joint of described patrix 1 is the evagination bending-like 14 matched with the die joint of described counterdie 2, described upper impression 11 is arranged along the trend of the evagination bending 14 of the die joint of described patrix 1, and the front end 15 of patrix 1 is run through in the lower end of described upper impression 11, form upper cavity opening 151.When matched moulds time, upper cavity opening 151 and lower mode cavity opening 271 are combined into mold cavity openings, and mold cavity openings is now in the minimum point of unitary mould, and when mould leaves stock tank, the unnecessary slurries in die cavity can be discharged from mold cavity openings automatically; Happier in order to make slurries discharge, die cavity lower impressions 21 being positioned at the die joint lower curtate of counterdie is set to tilt to the front end of counterdie 2, and plasma discharge is more suitable under gravity, more effectively improves the problem of paper kettle wall unevenness.Preferably lower impressions 21 being positioned at the shape that the shape of the die cavity of the die joint lower curtate of counterdie and upper impression 11 correspond to the die cavity of the die joint lower curtate of counterdie 21 and being set to circular arc, also can be other different shapes.Preferably upper connection interface 13 is communicated with lower the lower curtate 25 that interface 23 correspondence is located at the die joint of patrix 1 and counterdie 2.
As shown in Figures 2 and 3, in order to make upper and lower mould 1,2-in-1 mould more accurate, the die joint of counterdie 2 is provided with alignment pin, and the die joint of described patrix 1 is provided with the pin-and-hole 16 with described detent fit; Or the die joint of described patrix 1 is provided with alignment pin, the die joint of described counterdie 2 is provided with the pin-and-hole with described detent fit.
