Abstract
The invention discloses a low-pressure injection molding backrest protecting plate. The low-pressure injection molding backrest protecting plate comprises a PVC leather and a plastic piece body; the PVC leather is a non-woven cloth leather, and adopts a three-layer structure; the lowermost layer is a non-woven cloth layer; the middle layer is a foaming layer; the uppermost layer is a surface layer; and the PVC leather is absorbed on the plastic piece body. The low-pressure injection molding backrest protecting plate adopts a machine arm to take pieces, prevents workers from taking the pieces by hands, reduces the labor force of operators, can reasonably adopt the leather size to prevent redundant leather wastes, and performs a low-pressure injection molding process to reach the requirement of totally absorbing the PVC leather on the surfaces of plastic pieces.
Description
Technical field
The present invention relates to automobile industry technical field, more particularly, to a kind of low-pressure injection molding backrest backplate.
Background technology
Low-pressure injection molding technology is a kind of injection pressure of use very little（It is usually 0.15～4Mpa）Encapsulating material is injected
Mould is simultaneously fast curing-formed（It is usually 5～50 seconds）Packaging process, with reach insulation, heatproof, shock resistance, vibration damping,
The effects such as protection against the tide, waterproof and dustproof, resistance to chemical attack etc..This technique originates from the auto industry in Europe, up to the present in Europe
The auto industry field of U.S., Japan and Korea S etc. the and electric field successful Application more than ten years, still it is at present just in China
Step section.Its application widely, including：Printed substrate（PCB）, automobile electronics, automotive wire bundle, automobile-used connection
Device, sensor, microswitch, antenna etc..
Current automobile back backplate in manufacturing process, complex process, use artificial pickup and suspension member, time-consuming take
Power, leather absorption is easy to fall off in frosting.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, there is provided a kind of low-pressure injection molding backrest backplate.
The present invention is to be achieved through the following technical solutions：
A kind of low-pressure injection molding backrest backplate, including PVC leather and working of plastics body, described PVC leather is non-woven fabrics leather,
PVC leather is three-decker, and orlop is nonwoven layer, intermediate layer is foaming layer, the superiors are epidermal area, described PVC skin
Leather absorption is on working of plastics body.
Further, the thickness of described PVC leather is 1.0-1.2mm.
The low-pressure injection molding technology of the present invention is：
Before injection, using mechanical hand by PVC leather hanging on mould dynamic model, hang leather when, need ensure hang skin direction just
Really, the epidermal area be aligned mould dynamic model die cavity of PVC leather, nonwoven layer is directed at stationary mould for mould direction.
In injection, input low-pressure injection molding technology, active and inactive mold mold-closing injection, PVC leather is clipped in die cavity.Rear mold with set
Standby screw rod connection carries out heat injection plastics, after pressure thermoplastic materialss enter mold cavity, after contacting with the nonwoven layer of PVC leather
Infiltration bonding each other, when product saturation, Stress Release, epidermal area leather lines is strutted, after the completion of product injection, opens
Mould pickup, after product cools down completely, reaches absorption purpose completely.
Compared with prior art, the invention has the beneficial effects as follows：The present invention adopts robot arm pickup, it is to avoid workman is manual
Pickup, reduces operator labour force；Leather size can rationally be adopted, it is to avoid unnecessary leather wastes；Carry out low-pressure injection molding technology,
PVC leather can be reached and adsorb the requirement in plastic part surface completely.
Brief description
Fig. 1 is the front view of the present invention；
Fig. 2 is the right view of the present invention.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
Refer to Fig. 1 and Fig. 2, Fig. 1 is the front view of the present invention, Fig. 2 is the right view of the present invention.
A kind of described low-pressure injection molding backrest backplate, including PVC leather 1 and working of plastics body 2, described PVC leather 1 is no
Spin cloth leather, PVC leather 1 is three-decker, orlop is nonwoven layer 11, intermediate layer is foaming layer 12, the superiors are epidermis
Layer 13, described PVC leather 1 adsorbs on working of plastics body 2, and the thickness of described PVC leather 1 is 1.0-1.2mm.Working of plastics is originally
Body 2 structure division：Die sinking data that overall structure is provided by client and 2D drawing carry out mould processing, corresponding card contact,
Join the product data that point, size etc. all meet the requirements of the customers.
Before injection, using mechanical hand by PVC leather hanging on mould dynamic model, hang leather when, need ensure hang skin side
To correct, the epidermal area 13 be aligned mould dynamic model die cavity of PVC leather 1, nonwoven layer 11 is directed at stationary mould for mould direction.
In injection, input low-pressure injection molding technology, active and inactive mold mold-closing injection, PVC leather 1 is clipped in die cavity.Rear mold with
The connection of equipment screw rod carries out heat injection plastics, the nonwoven layer 11 after pressure thermoplastic materialss enter mold cavity, with PVC leather 1
Infiltration bonding each other after contact, when product saturation, Stress Release, epidermal area 13 leather lines is strutted, product is molded
After the completion of, mold pickup, after product cools down completely, reach absorption purpose completely.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
