Abstract
The invention discloses a fabric coated one-time injection molding die structure containing a general structure of ordinary dies. The die structure is characterized in that: a spring-mounted push plate is added in the die, during die assembly, a female die and the push plate pulls and holds a fabric, the push plate is pushed to tension the fabric, at the same time the spring is compressed, so that the push plate combines tightly with the female die under the elastic force of the spring, the die can have a pre-pressure before injection molding, the fabric put in the die in advance can be stable, and the shell fabric does not wrinkle.
Description
Technical field
The present invention relates to polymer material molding field, the coated single injection-molded mould structure of a kind of fabric.
Background technology
Along with the development of auto industry, the quality requirements of people to automobile is more and more higher.In the past near during the decade, the auto output of China achieves and significantly increases.Along with the raising of people's living standard, the care being also more and more subject to consumer attractive in appearance of automobile.In current injection moulding process, hang cloth on mould, direct matched moulds with manipulator, high molecular polymer melt injects in die cavity, makes the coated single injection-molded of fabric.
In decorations post on current medium-to-high grade automobile, door-plate, numerous part such as panel, handrail adopts the coated single injection-molded technique of fabric mostly, there is advantage that is attractive in appearance, good hand touch, because fabric is being fixed with in injection moulding process, the structure of neither one fixed fabric, fabric can be made wrinkling, the defect such as bleed, deformation texture easily to occur, the more difficult control of its moulding process.
Summary of the invention
To be solved by this inventionly be, in decorations post on current medium-to-high grade automobile, door-plate, numerous part such as panel, handrail adopts the coated single injection-molded technique of fabric mostly, there is advantage that is attractive in appearance, good hand touch, because fabric is being fixed with in injection moulding process, the structure of neither one fixed fabric, fabric can be made wrinkling, the defect such as bleed, deformation texture easily to occur, the problem of the more difficult control of its moulding process.
Technical scheme of the present invention is, the coated single injection-molded mould structure of a kind of fabric, comprises general mould universal architecture, it is characterized in that: add the push pedal that is equipped with spring in a mold, during mould matched moulds, fabric is held in master mold and push pedal, promotes push pedal tension fabric, make spring-compressed simultaneously, thus push pedal by the elastic force of spring, can be combined closely with master mold, makes mould just have a precompressed before injection moulding, make the fabric that puts in advance firm, fabric is wrinkle resistant.
The invention has the beneficial effects as follows, in injection moulding, greatly reduce percent defective, improve the quality of products, and simple to operate, be convenient to control.
Accompanying drawing explanation
Fig. 1 is matched moulds pre-structure schematic diagram of the present invention
Fig. 2 is structural representation after matched moulds of the present invention
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Referring to Fig. 1, wherein comprise (1) manipulator, (2) fabric, (3) gas folder, (4) spring, (5) male model, (6) hopper, (7) screw rod, (8) magnetic board, (9) core location-plate, (10) push pedal, (11) die cavity, (12) master mold.
As shown in Figure 1, (1) (2) fabric (3) gas folder is fixed in (10) push pedal by manipulator, after (1) manipulator retreats to home, start matched moulds, when (12) master mold touches (10) push pedal, (10) (2) fabric is pushed down in push pedal together, after promoting (10) push pedal, (2) fabric is driven to stretch backward, due to spring force effect, make (2) fabric tight wrinkle resistant, be pushed into (9) core location-plate always, (10) (11) die cavity bounce is given in push pedal, thus make just have precompression in injection moulding front mold, this makes (2), and fabric is firm.
As Fig. 2 state, (7) screw rod starts injection of plastic melt, and injection machine system terminates, and after die sinking, product takes out by (1) manipulator.
The present invention needs, by (5) male model and the transposition of (12) master mold, to be fixed on by (5) male model on (8) magnetic board, mobile (12) master mold; Utilize (4) spring force, make (12) master mold and (10) push pedal draw steady fabric, mould gives fabric a precompression, makes the fabric in mould firm.
Some sequelae of the original low-pressure injection molding of solution of science as: unstable, the product surface of material, size is easily wrinkling etc. thoroughly; And percent defective is greatly reduced in injection moulding, and improve the quality of products, and simple to operate, be convenient to control.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
Claims (1)
1. the coated single injection-molded mould structure of fabric, comprise general mould universal architecture, it is characterized in that: add the push pedal that is equipped with spring in a mold, during mould matched moulds, fabric is held in master mold and push pedal, promote push pedal tension fabric, make spring-compressed simultaneously, thus push pedal can by the elastic force of spring, combine closely with master mold, make mould before injection moulding, just have a precompressed, make the fabric that puts in advance firm, fabric is wrinkle resistant.
