Abstract
The invention discloses a manufacturing method of an air-conditioning panel with high glossiness, high brightness and no weld marks. The method comprises the following steps: heating a fixed mould cavity at first, filling the fixed mould cavity with raw materials by a plastic injection machine when the fixed mould cavity is heated and reaches to a set temperature, cooling the fixed mould cavity after plastic injection, and demoulding and taking out after solidifying and shaping the raw materials, wherein the raw materials for the plastic injection are prepared by adding PMMA (polymethyl methacrylate) materials to ABS (acrylonitrile butadiene styrene) materials as basic materials. The PMMA materials are good in flowability and can be used for improving the surface quality of the injection moulded panel and enabling the produced panel to be high in surface glossiness and brightness; a mould adopts steam for heating the fixed mould cavity, so that the heat exchange speed is high.
Description
Technical field
The present invention relates to household electrical appliances and manufacture field, particularly a kind of air-conditioning panel manufacture method.
Background technology
Along with social progress, people's living standard improves constantly, the requirements such as surface quality to air-conditioning products are also improving constantly, but the general raw material of utilization used in the prior art, and the panel surface that the mould of ordinary construction and conventional injection molding process are produced is coarse, surface not gloss and brightness low, some places also there will be weld mark, have affected the overall quality of air-conditioning products.
Summary of the invention
Technical problem to be solved by this invention is to provide the air-conditioning panel manufacture method of a kind of high gloss, high brightness, weldless trace.
For solving the problems of the technologies described above adopted technical scheme, be: first cover half die cavity is heated, when being heated to design temperature, with injection machine, raw material are injected in cover half die cavity cover half die cavity, after completing Deng injection moulding, to cover half die cavity, carry out cooling, after raw material solidifying and setting, the demoulding is taken out, and the raw material that injection moulding is used be take ABS material as base material interpolation PMMA material composition.
Further, described cover half die cavity is carried out to the processing of surface mirror mirror polish.
Further, the cover half mold cavity surface roughness after described surface finish processing is less than or equal to 0.012 μ m.
Further, adopt steam-heated method to heat cover half die cavity.
Further, the design temperature scope that described cover half die cavity is heated to is 115 ℃ to 122 ℃.
Further, cover half die cavity is carried out with recirculated water, the temperature of cover half die cavity being cooled to when cooling the temperature range of 55 ℃ to 62 ℃.
While further, raw material being injected in cover half die cavity with injection machine, adopt more than 80mm/s injection speed and injection pressure more than 150MPa.
The invention has the beneficial effects as follows: the raw material that injection moulding is used be take ABS material and added PMMA material composition as base material, and such composition mobility is strong, can improve the surface quality of injection mo(u)lding rear board, make the panel surface glossiness produced high, brightness is high.Mould adopts Steam Heating cover half die cavity, exchange rate is fast, mold temperature rises soon, rises highly, can within half a minute, mold temperature be elevated to design temperature, and can from heating mode, switch to refrigerating mode at any time, or switch to heating mode from refrigerating mode, to shorten molding cycle, enhance productivity.
The specific embodiment
Below the invention will be further described.
The air-conditioning panel manufacture method that the present invention is claimed; first cover half die cavity is heated; when being heated to design temperature, with injection machine, raw material are injected in cover half die cavity cover half die cavity; after completing Deng injection moulding; to cover half die cavity, carry out cooling; after raw material solidifying and setting, the demoulding is taken out, and the raw material that injection moulding is used be take ABS material as base material interpolation PMMA material composition.The high light high fluidity of former material is added appropriate PMMA material composition in ABS material, makes raw material have the feature of high light high fluidity, the glossiness and the brightness that have greatly improved composite.With the product surface after this forming materials, there is high brightness, the quality of high glaze.
Described cover half die cavity is carried out to surface finish processing.After the surface finish of sizing die cavity is processed, the product surface being in contact with it is low at injection mo(u)lding rear surface roughness value, surfacing gloss.
Cover half mold cavity surface roughness after described surface finish is processed is less than or equal to 0.012 μ m.Product surface when cover half mold cavity surface roughness is less than or equal to 0.012 μ m after injection mo(u)lding guarantees lower processing cost when reaching the effect of high glaze, high brightness.
Adopt steam-heated method to heat cover half die cavity.The temperature of steam can reach more than 140 ℃, exchange rate is fast, cover half die cavity temperature rises soon, rises highly, can within half a minute, cover half die cavity temperature be elevated to 120 ℃, and can from heating mode, switch to refrigerating mode at any time, or switch to heating mode from refrigerating mode, to shorten molding cycle, enhance productivity.Cover half die cavity temperature is high, and the temperature difference of raw material and cover half die cavity is little, and raw material cooling curing speed in die cavity slows down, and the mobile resistance of raw material diminishes relatively, and raw-material like this flow velocity speeds, and can improve the high and brightness of glossiness after panel product moulding.
The design temperature scope that described cover half die cavity is heated to is 115 ℃ to 122 ℃.Raw material temperature in cover half die cavity temperature within the scope of this and injection molding process in process approaches, and raw material can flow freely each position that is fully filled into cover half die cavity, and the product structure after moulding is complete like this, and surface brightness and glossiness are high.
Cover half die cavity is carried out with recirculated water, the temperature of cover half die cavity being cooled to when cooling the temperature range of 55 ℃ to 62 ℃.The temperature of cover half is cooled to 60 ℃ of left and right, is convenient to raw material cooling, solidifying and setting further in mould cavity.
With injection machine, raw material are injected to cover half.In the time of in die cavity, adopt more than 80mm/s injection speed and injection pressure more than 150MPa.Adopt above-described injection speed injection pressure can make the flowing velocity of raw material in die cavity accelerate, panel product glossiness and brightness after moulding all can effectively be improved.
