Abstract
The invention discloses a kind of blow molding methods of plastic mould, include the following steps：Shaped plastics embryo is made in raw material after plasticizing to be put into extrusion equipment, part type embryo is intercepted by the closure of extrusion equipment, and cutting type embryo, type embryo after cutting is put into preprepared mold cavity, and gaseous type embryo forming is filled in mold cavity, adjusting gas direction in real time by the thickness change of observation type embryo simultaneously makes type embryo consistency of thickness, type embryo is waited to cool and solidify again, open the product that mold cavity takes out curing molding, it is trimmed to obtain finished product again, guarantee the quality of blow molding part by the real-time oversight of production process, the plastic mould molding time is accelerated simultaneously, improve production efficiency.
Description
Technical field
The invention belongs to plastics-production manufacture fields, and in particular to a kind of blow molding method of plastic mould.
Background technique
Existing blow-molded article often because partly cause causes incomplete product more, such as is blown in process of manufacture
There is broken hole in modeling product, and also or blow-molded article thickness is different, influences using equally, during forming cooling, also going out
Now certain breakage, therefore cooling velocity is improved, the quality of product can be also improved to a certain extent.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of blow molding method of plastic mould,
Guarantee the quality of blow molding part by the real-time oversight of production process, while accelerating the plastic mould molding time, improves production
Efficiency.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of blow molding method of plastic mould, includes the following steps：
S1, it shaped plastics embryo is made in the raw material after plasticizing is put into extrusion equipment；
S2, part type embryo, and cutting type embryo are intercepted by the closure of extrusion equipment；
S3, the type embryo after cutting is put into preprepared mold cavity, and is filled with gaseous type embryo forming in mold cavity, together
When gas direction adjusted by the thickness change of observation type embryo in real time make type embryo consistency of thickness, then type embryo is waited to cool and solidify；
S4, the product for opening mold cavity taking-up curing molding, then trimmed to obtain finished product.
Preferably, the raw material in the step S1 includes synthetic resin, filler, plasticizer and lubricant.
Preferably, the filler includes glass fibre, asbestos and carbon black, the toughness of product is improved, prevents from being broken.
Preferably, the plasticizer is using phthalate organic compound.
Preferably, the lubricant includes stearic acid and calcium and magnesium salt.
Preferably, the synthetic resin, filler, plasticizer and lubricant mass ratio be 50 ~ 80：5~8：3~6：3~6.
Preferably, the gas in the step S3 is compressed air, and the temperature setting of compressed air is Celsius 3 ~ 10
Degree makes product accelerate molding by low temperature.
Preferably, the trimming in the step S4 is trimmed by grinding tool, the beauty of finished product is improved.
Usefulness of the present invention：The present invention is a kind of blow molding method of plastic mould, passes through the reality of production process
When supervision guarantee the quality of blow molding part, while the plastic mould molding time is reduced by Cryogenic air, raising production efficiency.
