Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention,
a processing method of a cast latex product comprises the following steps:
s1, plastic mold injection molding
Designing and producing a required injection molding mold, and then using the plastic mold required in the injection molding process processing, wherein the plastic material used by the plastic mold can not be melted or deformed at 150 ℃.
S2 injecting latex
Injecting the prepared latex into a plastic mold.
S3, heating and vulcanizing
Heating the plastic mould injected with the latex to 100-120 ℃ for vulcanization molding for 15-20 minutes.
S4, taking out the latex product
The mold was opened to remove the latex article. Then, the step S2 is repeated, and the process is repeated in a loop.
Note: the injection molding mold is arranged on an injection molding machine, and plastic materials can be used for injection molding to produce the plastic mold; the plastic mold is a mold for producing a latex product after injecting latex.
The cost of the injection molding plastic mold is 7-8 ten thousand yuan, the cost of the injection molded plastic mold is 50-100 yuan, 250 plastic molds are needed in one production line, and the direct cost is as follows: 100 × 250+80000=100500, i.e. not more than 10.5 ten thousand yuan at most, and the cycle of injection molding the plastic mold is 150-.
The aluminum mold is used, the cost of a single aluminum mold is 3000 yuan 2000, 250 aluminum molds are needed in one production line, and the direct cost is as follows: 3000 x 250=750000, that is, at most 75 ten thousand yuan is needed, while one machining center for machining the aluminum mold needs 1-2 days to complete, and paint spraying needs 2-3 days, and a production line 250 sets of aluminum molds are machined according to the production scale of 10 machining centers, which needs a multi-month period.
To summarize: one production line can directly save 60 ten thousand yuan of mould cost.
