Description
Technical field
The present invention relates to a kind of plastics suction mould.
Background technology
Automotive upholstery in process of production, often needs to attach one deck diaphragm on its surface.Diaphragm needed to carry out plastics sucking moulding before being mounted on automotive upholstery.Plastics sucking moulding typical process flow is as follows: sheet material or sheet material heating, will heat sheet material or sheet material step up to be fixed on plastics suction mould, start vavuum pump be evacuated to vacuum suction moulding, cooling and shaping, unclamp gripper frame take off moulded products, pruning redundance.Plastics suction mould comprises dynamic model and base.Base is arranged several cores or die cavity, diaphragm under matched moulds state vacuum suction moulding on core or die cavity.
Because the automotive upholstery had is with wedge angle etc., needs attachment diaphragm thereon also must with such wedge angle.And negative angle often below the parting line of sharp corner.Therefore, when designing core or die cavity, some to be set accordingly diaphragm can be made to produce the back-off of wedge angle.During die sinking, diaphragm along with dynamic model to away from base direction motion make diaphragm demoulding.But, before the diaphragm depanning after shaping, be tightly coated on die surface.Due to the existence of back-off, diaphragm is easy to be pulled out of shape or pull open in back-off position, causes the diaphragm produced to become waste product, reduces the qualification rate of product.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, providing a kind of and helping the smooth demoulding of diaphragm when mould exists back-off, thus the plastics suction mould improving product percent of pass takes off back-off structure.
For realizing above object, the present invention is achieved through the following technical solutions:
Plastics suction mould, comprises base, and described susceptor surface is provided with die cavity or protrudes from the core of susceptor surface, it is characterized in that, also comprises stripper apparatus, and described stripper apparatus is arranged on base movably, and stripper apparatus protrudes from susceptor surface; Described stripper apparatus can move up and down perpendicular on the direction of susceptor surface, protrudes from susceptor surface or lower than susceptor surface.
Preferably, described stripper apparatus pressurized and move to and do not protrude from susceptor surface when plastics sucking moulding, and after distress resolves, automatically return to the position protruding from susceptor surface.
Preferably, described base offers the groove for accommodating described stripper apparatus, described stripper apparatus is arranged in described groove.
Preferably, also flexible member is comprised; Described flexible member produces elastic deformation force when stripper apparatus pressurized moves, and this elastic deformation force can make stripper apparatus return back to the position protruding from susceptor surface.
Preferably, described stripper apparatus is pushing block.
Preferably, described flexible member is spring.
Preferably, described stripper apparatus is pushing block, and described base arranges the first accepting groove, and described pushing block arranges the second accepting groove; First accepting groove is relative with the second accepting groove position; Described both ends of the spring lays respectively in the first accepting groove and the second accepting groove.
Preferably, be also included in the guider of guiding when stripper apparatus moves up and down, described guider to be arranged on base and to match with stripper apparatus.
Preferably, described base offers the groove for accommodating described stripper apparatus, described stripper apparatus is arranged in described groove; Described stripper apparatus offers guide groove, and described guide groove coordinates with described guider.
Preferably, described core or die cavity are more than two rows, and often row's core or number of cavity are more than one; Described stripper apparatus is arranged between two row's cores or die cavity.
Plastics suction mould in the present invention, during plastics sucking moulding, stripper apparatus pressurized moves to the position not protruding from susceptor surface, does not hinder plastic uptake, also can not cause diaphragm deformation; After diaphragm plastics sucking moulding, after pull of vacuum disappears, stripper apparatus can automatically return to the position protruding from susceptor surface; Can diaphragm be promoted in stripper apparatus moving process, make the first demoulding of the part of diaphragm near back-off place.Therefore the demoulding of full wafer diaphragm is contributed to.Use the plastics suction mould in the present invention, can avoid diaphragm be stretched at back-off place in de-filming process distortion, draw bad, improve product percent of pass.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1 and Figure 2: plastics suction mould, base 4 is comprised.Base 4 is provided with two row's cores 42, often arranges 3.Core 42 protrudes from the surface 43 of base 4.Core 42 has back-off 421.Base 4 is provided with groove 41.Groove 41 is between two row's cores 42.Plural first accepting groove 44 is provided with in groove 41.
Also comprise pushing block 1, Compress Spring 2 and guider 3.Pushing block 1 is arranged in the groove 41 of base 4 movingly.Pushing block 1 offers guide groove 13.Pushing block 1 is provided with plural second accepting groove 14.Each second accepting groove 14 is relative with one of them first accepting groove 44 position.Compress Spring 2 one end is positioned at the first accepting groove 44, and the other end is positioned at the second accepting groove 14.Pushing block 1 pressurized moves to and does not protrude from surface 43 process of base 4, is that Compress Spring 2 is produced elastic deformation force by compressing.This elastic deformation force can make pushing block 1 return back to protrude from the position on base 4 surface 43 after the distress resolves to pushing block 1.
Guider is guide post 3.Guide post 3 is arranged on base 4, and matches with gathering sill 13.When pushing block 1 moves, move axially along guide post 3.
Plastics suction mould of the present invention takes off the operation principle of back-off structure, and details are as follows:
As shown in Figures 3 to 5, first the diaphragm after heating is positioned on the surface 43 of base 4, covers whole susceptor surface 43.Now the upper surface 11 of pushing block 1 is in and protrudes from surface 43.After matched moulds, carry out supercharging to diaphragm outer surface, inner surface vacuumizes, thus makes membrane attaching on core 42.Pushing block 1 moves and compresses Compress Spring 2 under the pressure of diaphragm.Until the upper surface 11 of pushing block 1 flushes with surface 43.After diaphragm plastics sucking moulding, remove pull of vacuum, pushing block 1 is no longer under pressure, and the elastic force of Compress Spring 2 makes pushing block 1 move up to protrude from the position on surface 43.Promote diaphragm in pushing block 1 motion process, the part of diaphragm near back-off 421 place is thrown off from core 42.And then full wafer diaphragm demoulding.
When core 42 in the present embodiment is replaced by die cavity, it is applicable equally that plastics suction mould of the present invention takes off back-off structure.
Embodiment in the present invention, only for the present invention will be described, does not form the restriction to right, other equivalent in fact substituting, all in scope that those skilled in that art can expect.
