Description

IML film forming die

Technical Field

The utility model discloses a IML film forming die relates to film forming die equipment technical field.

Background

At present, the bottom plate is adopted for heating and conducting to the die, and the temperature of the heating sheet is controlled in a partitioning mode, but the die is molded at a fixed high temperature, so that the precise positioning and the material borrowing design are difficult to achieve.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the defect among the above-mentioned background art, provide an IML film forming die, adopt the subregion to separate the temperature design, make the temperature difference in every district, let low temperature district stereotype fast and accurate location, the high temperature region borrows the material tensile.

In order to achieve the above purpose, the utility model adopts the following technical scheme: an IML thin film forming die comprising: the mold comprises a mold base and a heating plate, wherein the heating plate is arranged on one side of the mold base, two mold cores are arranged on the other side of the mold base, a U-shaped heat insulation piece is arranged on the periphery of each mold core, the mold base is divided into a first area and a second area through the U-shaped heat insulation piece, and a U-shaped water pipeline is arranged inside the mold base and on the inner side and the outer side of the heat insulation piece respectively.

Furthermore, U-shaped grooves are formed in the periphery of the mold core, the heat insulation pieces are embedded in the U-shaped grooves, and the tops of the heat insulation pieces and the surface of the mold base are on the same plane.

Furthermore, the first area is a communicated M-shaped area on the mold base plate, the first area is a high-temperature area, the second area is two U-shaped areas respectively around the mold core, and the second area is a low-temperature area.

Furthermore, the mold core is made of aluminum or copper, so that the temperature conduction is rapid.

Furthermore, a water inlet and a water outlet of the water pipeline are both arranged on the same side wall of the mold chassis.

Furthermore, the water inlet of the water pipeline is positioned at two ends of the outer side of the mold chassis, and the water outlet is positioned in the middle of the mold chassis.

The utility model discloses when the product shaping stage, at first heat up the processing through the hot plate to the mould chassis, reach behind the settlement temperature A, through the U type water service pipeline to the heat insulating part outside let in the rivers that the temperature is higher than A, further raise the temperature to temperature B with first region, let in the rivers that the temperature is less than A to the inboard U type water service pipeline of heat insulating part, cool down the second region to temperature C, thereby there is the difference in temperature between control high-temperature region and the low temperature zone, thereby let the low temperature zone of product in the inboard can finalize the design fast and accurate location, the high temperature region in the outside can borrow the material tensile, after the product shaping, let in the U type water service pipeline of heat insulating part both sides the rivers that the temperature is less than temperature C, guarantee the synchronous cooling in first region and second region, make things convenient for the drawing of product, after the drawing of patterns, the production of next product is carried out to the above-mentioned step of circulation.

Has the advantages that: adopt the subregion to separate the temperature design in IML's film forming die, adopt time schedule controller to heat up the cooling treatment to the mould, every region adopts different heat-conducting material or water route, makes the temperature difference in every region, lets the low temperature district stereotype fast and accurate location, and the high temperature region is borrowed the material and is stretched.

The application range is wide, and the method is suitable for producing various IML films, such as various corresponding films of PC, PET, PMMA and the like.
