(2) vacuum male mould forming：Deficiency is that band lines epidermis molding process mesocuticle is easily pulled and lines loss, R
Angular position, which is pulled, to repair.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, there is provided a kind of automotive trim epidermis vacuum forming pressure
Line mould and its forming method.
The technical scheme that the present invention takes is as follows：
A kind of automotive trim epidermis vacuum forming embosses mould, it is characterised in that it includes baffle plate, the upper mould
The bottom of bottom plate is provided with the closed frame of mould, and the framework top of the upper closed frame of mould is provided with mould, and the upper mould is using saturating
Gas steel are made, and the porosity of the steel is at least 4/cm2More than, vacuum absorption holes φ 0.2- φ 0.3mm thereon are described
The middle part of upper baffle plate is provided with and vacuumizes hole；The lower section of above-mentioned upper mould is provided with lower mould, and the surrounding of lower mould is provided with the closed frame of lower mould,
The closed frame of lower mould is connected at work with the above-mentioned upper closed frame of mould, and the lower closed frame of mould is arranged on lower mould bottom plate
On, it is provided with the middle part of lower mould bottom plate and evacuates stomata.
The lower mould is made of aluminum alloy material.
Polylith space bar is provided between the bottom surface of the lower mould and lower mould bottom plate.
Present invention also offers a kind of forming method using above-mentioned mould, its technical scheme is：
Step 1：Incubator will be dried and be heated to 250-360 DEG C；
Step 2：Automotive trim epidermis to be processed is put into press box；
Step 3：Above-mentioned epidermis is entered into above-mentioned baking incubator with press box, and dries warm 30-40s；
Step 4：Press box and epidermis are taken out after the completion of baking temperature, above mould drops to pre-operation when press box starts to depart from baking incubator
Position；
Step 5：Epidermis is moved to upper mould and lower mould molding position with press box；
Step 6：Upper mould starts to inhale vacuum；
Step 7：Upper mould pushes, same to be pressed at present on mould；
Step 8：Pressurize 10-20s；
Step 9：Lower mould air blowing 1-3s after pressing；
Step 10：Product after shaping is taken out in die sinking.
Further, it is preferable to the baking temperature time in the step poly- three is 35s.
Further, it is preferable to the dwell time in the step poly- eight is 15s.
Further, it is preferable to the lower mould gassing time in the step poly- nine is 2s.
The beneficial effects of the invention are as follows：
1st, manufacture craft shortens:It can be processed using direct machine tooling mode, and there is no dermatoglyph stretcher strain and loss,
The defects of reducing present epidermis vacuum forming rate.
2nd, cost of manufacture reduces：Existing molds material cost is too high (mainly using Japanese gate-in mold system), now using common
Steel produce (lower mould aluminium section bar, upper mould air-permeable mold steel), and the input cost and production cost of equipment substantially reduce.
3rd, epidermis pressing texture is apparent, and the quality repetition stability of product is good, plastic less circular arc position.
4th, the manufacturing cycle is short.
