[background technology]
EPEAT(Electronic Product Environmental Assessment Tools, electronic product environmental assessment instrument) be admitted by Environmental Protection Agency in 2006, and by the nonprofit organization environment-friendly electronic committee (Green Electronics Council) based on IEEE 1680 specification work out an electronic product Green evaluation pointer of management.Along with the lifting of people's environmental protection ideas and carbon footprint etc. get more and more to product environmental requirement, EPEAT is more and more extensively employed.
There are the raw matter plastics of environmental protection as PLA alloy(polylactic acid alloy) on various product application start to occur, existing food containers adopts conventional petroleum base material matter to make, and all has problems to environment and resources recycling.
Along with people are to the raising of quality of life and environmental consciousness, someone starts to adopt this raw material of PLA (PLA) to make food containers.Such as when making has the boxed cassette of intermediate sealing strip and lower box body, the mode of prior art is fitted together for after independent design intermediate sealing strip and lower box body (the common ejection formation of PLA) part.
Adopt the product of said method manufacture can have following shortcoming: (1) in use greasy dirt and dirt easily accumulates at sealing strip place, and cleaning not easily, is not very practical; (2) two kinds of materials are independently produced and are assembled, compare work consuming consuming time.
In view of this, be necessary to develop a kind of plastic cement products and forming method thereof in fact, to solve the product cleaning problem not easily that work consuming when existing forming method is produced is consuming time and produce.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of plastic cement products and forming method thereof, saving of work and time when this forming method is produced, the product easy to clean of producing.
In order to achieve the above object, the forming method of plastic cement products of the present invention, described plastic cement products comprises the first component and second component that be combined with each other, and the method comprises the following steps:
(1) the Double-injection mold die sinking controlled by high-low temperature controller also heats up, and described Double-injection mold has first and penetrates mould and second and penetrate mould;
(2) penetrate mould to described first to carry out injection moulding first and penetrate material with the first component of this product shaping;
(3) controlled to cool injection mold by high-low temperature controller;
(4) penetrate mould to described first and carry out die sinking, penetrate the first shaping component by first and be put into second and penetrate in mould, injection moulding second penetrates material with the second component of this product shaping;
(5) product is taken out in die sinking.
Optionally, described first to penetrate material be PLA plastics.
Optionally, described first to penetrate material be the PLA alloys of PLA plastics through modified injection grade.
Optionally, described second to penetrate material be high temperature resistant silicon glue material, such as, be thermoplastic elastomer (TPE) TPSIV.
Optionally, described high-low temperature controller adopts high-speed and high-temperature forming technique (RHCM, Rapid HeatCycle Molding).
Described bicolor injection mould can be independent two covers, by rotating injection second component; Described bicolor injection mould also can be a mould two cave design, penetrates the first shaping component be put into first in second component mould
The present invention also provides a kind of plastic cement products, and this plastic cement products is the product produced after the forming method of described plastic cement products makes.
Optionally, described plastic cement products is food containers.
Optionally, described food containers has the lower box body and sealing strip that be combined with each other, and described lower box body and described sealing strip are respectively described first component and second component.
Compared to prior art, plastic cement products of the present invention and forming method thereof, due to be adopt double injection mould carry out shaping, therefore after shaping end, namely the first component of described product and second component combine, and described first component and second component are assembled without the need to producing separately again, time and labour saving, simultaneously, the product produced is structure as a whole, good airproof performance, easy to clean.
[accompanying drawing explanation]
Fig. 1 illustrates the flow chart of steps of the forming method of plastic cement products of the present invention.
[detailed description of the invention]
For having further understanding to object of the present invention, method step and effect, be now described with reference to the accompanying drawings as follows:
Refer to Fig. 1, Fig. 1 illustrates the flow chart of steps of the forming method of plastic cement products of the present invention.
In order to achieve the above object, the forming method of plastic cement products of the present invention, described plastic cement products comprises the first component and second component that be combined with each other, and the method comprises the following steps:
Step 101: the Double-injection mold die sinking controlled by high-low temperature controller also heats up, described Double-injection mold has first and penetrates mould and second and penetrate mould.
Step 102: penetrate mould to described first and carry out injection moulding first and penetrate material with the first component of this product shaping.
Step 103: controlled to cool injection mold by high-low temperature controller.
Step 104: penetrate mould to described first and carry out die sinking, penetrate the first shaping component to be put into second to penetrate in mould by first, injection moulding second penetrates material with the second component of this product shaping (wherein: described bicolor injection mould can be independent two covers, by rotating injection second component; Described bicolor injection mould also can be a mould two cave design, penetrates the first shaping component be put into first second and penetrate in mould).
Step 105: product is taken out in die sinking.
Wherein, described first penetrates material for PLA plastics, by the biodegradable plastic of PLA production and processing, can replace traditional petrochemical industry plastics used at present comprehensively, the raw material that tableware, operation suture thread, packaging material etc. need be degraded can be widely used in, improve Environmental Protection Level.
