Description
Technical field
The utility model relates to a kind of injection mold, especially a kind of high-light no-trace mould.
Background technology
Ordinary injection die, in the time that production outward appearance is the product of high light face, inevitably can produce weld bond, causes bad order.The product needed processing under this condition is carried out secondary surface treatment just can reach good surface effect, need to increase manufacturing procedure and carry out secondary surface treatment, need to use special material simultaneously, not only reduce production efficiency, and need to increase material cost, be unfavorable for the production in enormous quantities processing of product.
Utility model content
The utility model proposes and a kind ofly can obtain good surface effect, and enhance productivity, reduce the high-light no-trace mould of manufacturing cost.
The technical solution of the utility model is achieved in that
This mould comprises upper die and lower die that can folding, described patrix is installed in upper bolster, counterdie is installed in die shoe, after described upper die and lower die pressing, form die cavity, its improvement is: described upper bolster is provided with water inlet tap, in described patrix, be provided with circulation line, described water inlet tap is communicated with circulation line, and described water inlet tap connects steam generator and cooling water circulation equipment by transfer valve.
Preferably, in described patrix, be provided with temperature probe.
Preferably, described water inlet tap flatly passes respectively upper bolster and patrix by upper bolster both sides.
Preferably, between described patrix and upper bolster, be provided with the first thermal insulation board.
Preferably, described upper bolster upper surface is provided with the second thermal insulation board.
Preferably, described water inlet tap is that stainless steel lengthens water nozzle.
Preferably, in described die shoe and counterdie, be provided with a lifting thimble.
Preferably, described lifting thimble bottom is connected with an ejector retainner plate, and described ejector retainner plate bottom is provided with a top rod, and the position of the corresponding described top rod in die shoe bottom is provided with perforate.
Owing to having adopted technique scheme, high-light no-trace mould of the present utility model adopts high-temperature steam heating+water cooling, by the steam that uses 180 DEG C, die surface is rapidly heated, make more than shaping mold cavity surface temperature reaches the glass transition temperature (Tg – Glass TransitionTemperature) of plastics, then start to carry out ejection formation, when completing after mould filling process, utilize immediately water (treated) as cooling media, mold surface temperature to be declined rapidly, thereby change plastic product surface characteristic, thereby directly obtain ganoid product, without secondary operations, shorten production procedure, reduced production cost simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-4, the high-light no-trace mould of an embodiment of the present utility model comprises patrix 1 and counterdie 2 that can folding, described patrix 1 is installed in upper bolster 3, counterdie 2 is installed in die shoe 4, after described patrix 1 and counterdie 2 pressings, form die cavity 5, described upper bolster 3 is provided with water inlet tap 6, in described patrix 1, be provided with circulation line, described water inlet tap 6 is communicated with circulation line, and described water inlet tap 6 connects steam generator 8 and cooling water circulation equipment 9 by transfer valve 7.
When work, first produce the steam of 180 DEG C by steam generator 8, and transfer valve 7 is switched to steam generator 8 connected states, make more than shaping mold cavity surface temperature reaches the glass transition temperature (Tg – Glass TransitionTemperature) of plastics, then start to carry out ejection formation, when completing after mould filling process, immediately transfer valve 7 is switched, water inlet tap 6 is communicated with cooling water circulation equipment 9, now utilize water (treated) as cooling media, mold surface temperature to be declined rapidly, thereby change plastic product surface characteristic.
In order accurately to control patrix surface temperature, thereby obtain good product surface effect, in the present embodiment, in described patrix 1, be provided with temperature probe 10.
When making Steam Heating, on mould, obtain uniform heating-up temperature, in the present embodiment, described water inlet tap 6 by upper bolster 3 both sides respectively flatly through upper bolster 3 and patrix 1.
