Abstract
The invention discloses a technology for processing a bright decoration panel. The processing technology comprises the following steps: A, drying plastic particles, and increasing the temperature of a charging barrel and an injection mould, wherein a front mould is at 75 DEG C and a rear mould is at 65 DEG C; B, performing multi-segment injection and discovering each flaw occurrence position via short injection, wherein the injection speed sequentially adopts low speed, middle speed and low speed, finally middle-speed and middle-high-pressure injection is performed, the pressure maintains compact and is kept within 8-9Mpa; C, cooling the product after injection molding, wherein the cooling time is within 60-65s; and D, opening the mould and ejecting the bright decoration panel by an ejection device, wherein the ejection speed is within 10-15mm/s. By adopting the processing technology, the surface flaw of the product is greatly reduced and the qualification rate of the product is effectively improved, thereby ensuring steady production and reducing debugging time.
Description
Technical field
The present invention relates to sheet fabrication field, relate in particular to a kind of bright plaque processing technology.
Background technology
Light height plaque is high to its surface requirements, existing bright plaque adopts injecting molding die to process, in existing bright plaque processing technology, the front mould temperature of injecting molding die is 70 degrees Celsius, rear mold temperature is 60 degrees Celsius, after injection moulding, cool time is 50 seconds, and do not adopt multistage to inject, the goods batch obtained thus is long, and thickness is thicker, easily shrinks in muscle position,, also there is cast gate place in addition and produce that spray pattern, reinforcement are easily broken, surface easily produces the problem such as current mark, weld bond in low qualified.
Summary of the invention
The object of the invention is will provide a kind of bright plaque processing technology, to solve the problems of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
Light plaque processing technology, is characterized in that, comprise the following steps,
A, first dried by plastic particles, and improve barrel, injecting molding die temperature, front mould 75 degrees Celsius, rear mold temperature is 65 degrees Celsius;
B, with multistage injection, with short penetrate find out position that each defect occurs after, injection speed first adopts low speed, middling speed, again low speed, and finally with the injection of middling speed mesohigh, pressurize is compact, and dwell pressure is 8-9Mpa;
After C, injection moulding, cool product, cool time is 60-65s;
D, die sinking, ejected bright plaque by liftout attachment, and the speed of ejecting is 10-15mm/s.
Adopt bright plaque processing technology of the present invention that surface defects of products is reduced greatly; Effectively raise product percent of pass; Ensure steady production, reduce debug time.
The detailed description and obtaining that feature of the present invention can consult the better embodiment of below this case is well understood to.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
A kind of bright plaque processing technology, comprises the following steps:
A, first dried by plastic particles, and improve barrel, injecting molding die temperature, front mould 75 degrees Celsius, rear mold temperature is 65 degrees Celsius;
B, to inject with multistage, with short penetrate find out each defect occur position after, injection speed first adopts low speed, middling speed (make reinforcement welding effective), again low speed (solving the problem of surface flow marks, weld bond), finally with middling speed mesohigh injection (guarantee is made), pressurize is compact, and dwell pressure is 8-9Mpa;
After C, injection moulding, cool product, cool time is 60-65s;
D, die sinking, ejected bright plaque by liftout attachment, and the speed of ejecting is 10-15mm/s.
Adopt bright plaque processing technology of the present invention that surface defects of products is reduced greatly; Effectively raise product percent of pass; Ensure steady production, reduce debug time.
More than show and describe general principle of the present invention, 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; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
