The utility model discloses a deferent forming die is watered to paper for casting, when having solved moulded product, the first half of product dehydration is not done, the port is irregular and product the first half and the many thick liquids of the latter half butt joint department cause the drawback that product appearance is not bright and clean, has improved the quality and the yield of product.
Description
Technical field
This utility model relates to the mould of a kind of paper pouring channel tube for casting。
Background technology
In prior art, metal casting pouring channel tube generally all adopts the refractory materials such as pottery, porcelain to make, but complex manufacturing process, production cost is high, and environmental pollution is big。The patent No. is the moulding process that the paper pouring channel tube for casting of 200910117239.6 and the patent of invention of moulding process thereof disclose a kind of paper runner channel pipe, the serosity of paper pulp fiber and reinforcing agent, anti-blushing agent material composition is sent into mould by it, then through the making completing paper runner channel pipe after the operations such as dry, shaping。Therefore, paper runner channel pipe mold is designed to a difficult problem for paper runner channel pipe molding。Currently mainly adopt and split mould by what there is air extractor with hole pattern mould, insert evacuation dehydration in quantitative headbox, by fibers adsorption in mould inner surface, expose the transferred product of molding after liquid level until mould。Easily occur that became uneven is even, the first half moisture content is too high by the product of the method molding, dry and molding the product port cross-sectional of dehydration is irregular, the many slurries of joint and cause product appearance not bright and clean phenomenon, the product percent defective causing molding is high, outward appearance is plain, slurry waste is many and became uneven, has a strong impact on product quality。
Summary of the invention
This utility model is for above-mentioned problems of the prior art, a kind of paper pouring channel tube for casting mould is provided, when solving shaped article, the first half dehydration of product is dry, port is irregular and product the first half and the many slurries of the latter half joint cause the not bright and clean drawback of product appearance。
Design of the present utility model is as follows: a kind of paper pouring channel tube for casting mould, including shaping upper with holes and molding counterdie, the reverse side of shaping upper and molding counterdie is provided with air chamber, it is provided with vacuum tube interface at the both sides place of shaping upper air chamber, vacuum tube interface communicates with the dehydration groove with outwards one-tenth constant slope in air chamber, each port of shaping upper and molding counterdie is fixed with block arc, the thickness of block arc higher than the wall thickness of product of institute's molding, is provided with step and sealing gasket on the face fitted with shaping upper of molding counterdie。
Further, the aperture in the hole on shaping upper chamber wall is more than the aperture in the hole on molding lower mode cavity locular wall。
Further, being provided with the hole of diameter 3mm, spacing 4mm on the wall of shaping upper chamber, become plum blossom-shaped arrangement, be provided with the circular hole of diameter 2mm, spacing 4mm on the wall of molding counterdie chamber, linear array arranges。
Further, it is provided with locating piece at four angles place of shaping upper, is provided with, at four angles of molding counterdie place, the groove matched with locating piece。
Paper pouring channel tube for casting mould of the present utility model, when solving shaped article, the first half dehydration of product is dry, port is irregular and product the first half and the many slurries of the latter half joint cause the not bright and clean drawback of product appearance, improves quality and the yield rate of product。

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail。
As shown in Fig. 1 Fig. 4, the paper pouring channel tube for casting mould of the present embodiment mainly includes shaping upper 1, molding counterdie 2, the reverse side of shaping upper 1 and molding counterdie 2 empties formation air chamber when keeping certain wall thickness, and be fixed with block arc 3 in each port of shaping upper 1 and molding counterdie 2, and thickness is higher than the wall thickness of the product of institute's molding；It is provided with vacuum tube interface 5 at the both sides place of shaping upper 1 air chamber, vacuum tube interface 5 communicates with the dehydration groove 6 with outwards one-tenth constant slope in air chamber, and the wall of its chamber is drilled with the circular hole of diameter 3mm, spacing 4mm, become plum blossom-shaped arrangement, be provided with locating piece 7 at four angles place of shaping upper。Being drilled with the circular hole of diameter 2mm, spacing 4mm on the wall of molding counterdie 2 chamber, linear array arranges；It is provided with the groove 8 matched with locating piece 7 at four each angle places of molding counterdie 2, and is provided with step 9 deep for 0.5mm on the face that itself and shaping upper 1 fit, and the sealing gasket 4 that will be above step depth is fixed on above。
During molding, the cooperation location matched moulds of shaping upper 1 and molding counterdie 2 located piece 7 and groove 8, and the sealing gasket 3 on molding counterdie 2 is compressed formation and matched moulds contact surface gastight cavity consistent with shape of product, and shaping upper 1 is on molding counterdie 2；Then the mould getting togather mould is put in the slurry pool preparing material, the air chamber of shaping upper 1 and molding counterdie 2 passes into vacuum simultaneously, slurry is entered in chamber by the block arc 3 on mould port, it is adsorbed on die surface and forms product 10, owing to the thickness of block arc 3 is higher than the wall thickness of required product 10, then will not arbitrarily be adsorbed on die surface in the port of product, and be to maintain the cross section consistent with block arc 3 cross section, solve the irregular phenomenon of product port cross-sectional。Water in the slurry then hole on mold wall sucks in air chamber, water in shaping upper 1 air chamber then accumulates in dehydration groove 6, owing to de-water trough design becomes constant slope to vacuum tube interface, therefore air chamber will not accumulate the water deviate from from product for a long time and be back to product 10 up, so solving the drawback that product the first half moisture content is too high。And matched moulds contact surface is to compress airtight by sealing gasket 3, then slurry will not be adsorbed onto the surface of product by the effect of vacuum through the gap of mould contact surface, makes the product surface of molding without unnecessary slurry, thus without influence on outward appearance。Because slurry has downward precipitability, when passing into vacuum at the same time, the slurry of molding counterdie 2 absorption is higher than shaping upper 1, it is adjusted the size in aperture and when the quantity in hole is constant, make the slurry that shaping upper 1 adsorbs more than molding counterdie 2, so solving the phenomenon of product became uneven
Particular embodiments described above; the purpose of this utility model, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
