Description

A kind of keyboard top cover bloom is without current mark mold

Technical field

The utility model relates to a kind of technical field of mold, in particular to a kind of keyboard top cover bloom is without current mark mold.

Background technique

Bloom specular appearance is the important symbol of high-end product, to accomplish bloom mirror effect (roughness in key mouse field Reach 0.005 ~ 0.01 μm of Ra), generally use injection molding production after again with spraying or other aftertreatment technologies realize, not only at This height, and cause serious pollution to the environment.

Keyboard top cover product appearance requires SPI A-2 mirror effect and weldless trace, needs using 120 ~ 150 DEG C of high mold temperatures Ability injection molding go out high mirror surface, product without appearance weld mark effect.Traditional high mold temperature generallys use die heater or oil Warm machine heats and cools down mold, but the cooling velocity of mold is slow, inefficient.

There is the Chinese patent of a Publication No. 201192889Y at present, discloses a kind of mould of the bloom without molten trace Shooting Technique Tool, the injection mold include at least dynamic model and cover half, heating element are embedded in dynamic model and cover half, and it is logical to be provided with cooling water Road.Temperature sensor also can be set in dynamic model and cover half.The utility model is embedded with heating element in mold, is provided with Cooling-water duct.It can be seen that the mold cooling velocity is slow, and it is inefficient, it cannot achieve the function of rapidly heating, rapid cooling Can, not only not environmentally again increase production cost.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of rapidly heating, rapid cooling and environmentally protective keyboards Upper cover bloom is without current mark mold.

The technical scheme adopted by the utility model is the utility model includes steaming plant and high-temperature resistant tube, mold sheet Body and be arranged in the die ontology side mold chamber, the inside of the mold chamber include input extension pipe, output plus Long tube, die cavity temperature-sensitive needle, hot runner gate and die cavity air flue, the input extension pipe and the output extension pipe with the die cavity Air flue is connected, and the inside of the mold chamber, the output end of the hot runner gate is arranged in the induction end of the die cavity temperature-sensitive needle It is connected with the die ontology, the steam output end of the steaming plant and the input extension pipe pass through the high-temperature resistant tube Connection, the steam input terminal of the steaming plant are connect with the output extension pipe by the high-temperature resistant tube.

By above scheme as it can be seen that in the present invention, steaming plant is rapid heat cycle steaming plant, possess 150 DEG C of steamings Vapour mode and cooling aqueous mode, can make die cavity reach 120 ~ 150 DEG C or be quickly cooled down mold chamber；High-temperature resistant tube is high temperature resistant Teflon pipe, effect are to be passed through die cavity by high temperature resistant Teflon pipe when rapid heat cycle steam, are brought rapidly up；Input extension pipe and Output extension pipe passes through high temperature resistant Teflon pipe respectively and connect with rapid heat cycle steaming plant, forms steam-return line or cools back Environmentally protective heat transfer and cold conduction are realized in road, and die cavity temperature-sensitive needle is for monitoring whether die cavity room temperature reaches predetermined value, heat Runner mouth is connected to die ontology, and the heat of mold chamber can be made to be passed through die ontology；The utility model, which is realized, rapidly to heat up, is anxious The method of quickly cooling but had not only met product apperance but also had met short-period injection molding production.This method is not only environmentally friendly but also reduction is produced into This, protects the health of operator, realizes the energy-saving of green.

Further, the die cavity air flue is the die cavity air flue of several uniform compact arrangements, and the die cavity air flue is close The surface of the mold chamber.

By above scheme as it can be seen that in the present invention, die cavity air flue is uniformly arrangement, diameter 8, the spacing 16 of air flue ~ 20mm, apart from mold cavity surface 10mm or so, too close mold is easy cracking, too far to be unfavorable for quickly increasing mould-cavity temperature.Mode Mold is constantly deformed, is shunk when material will meet rapid heat cycle, the good toughness such as material selection import CENA1, ASTM, high temperature resistant, The excellent material of polishing performance.

Further, the bottom of the mold chamber is provided with thermal insulation board.

By above scheme as it can be seen that in the present invention, since mode temperature is high, reducing mold chamber heat outward as far as possible It scatters and disappears, mold chamber bottom increases thermal insulation board, and some empty avoidings are done in the contact surface reduction of side and mode.

Further, guide-post of die-set is provided in the die ontology, the guide-post of die-set is arranged with copper and graphite mould is added to lead Set.

By above scheme as it can be seen that in the present invention, mould has steam heating before mold, inevitably temperature can be than preceding Mould temperature is high, and guide-post of die-set holds to be burnt to death very much, and guide sleeve adds graphite mould guide sleeve using copper, and the big mold for tonnage in 650T or more can With use side's guide post.

Further, the high-temperature resistant tube is high temperature resistant Teflon pipe.

By above scheme as it can be seen that in the present invention, high-temperature resistant tube is high temperature resistant Teflon pipe, effect is when anxious heat is steamed Vapour is passed through mold chamber by high temperature resistant Teflon pipe, can be brought rapidly up, and when coolant liquid is passed through mold chamber, can cool down rapidly.

Further, the steaming plant is rapid heat cycle steaming plant.

By above scheme as it can be seen that in the present invention, rapid heat cycle steaming plant possesses 150 DEG C of steam modes and cold But aqueous mode can make mold chamber reach 120 ~ 150 DEG C or be quickly cooled down mold chamber.
