Automatic demolding method applied to automobile plastic part and injection mold thereof

Abstract

The invention provides an automatic demolding method applied to an automobile plastic part and an injection mold of the automobile plastic part. The method comprises the following steps that an injection molding material is prepared to be thick, a spraying device is used for spraying the injection molding material to a child mold and a mother mold of the mold, and then the spraying device is removed; combining the son mold and the mother mold of the mold, and separating the son mold and the mother mold after the injection molding material is completely cooled through compression molding; the edge of the mold is pressed to remove burrs of the plastic part in the demolding process; the injection mold comprises two turnover mechanisms which are arranged on the two sides of the supporting mechanism in a bilateral symmetry mode, and each turnover mechanism is provided with a mold mechanism. The power mechanism is arranged in the middle of the supporting mechanism; the spraying mechanism is arranged in the middle of the upper side of the supporting mechanism; compared with a traditional injection molding device, the arrangement that a plastic part is generated in a spraying and compression molding mode does not need to change the temperature of a child mold and a mother mold of the mold in the injection molding process, and the child mold and the mother mold of the mold can be directly closed under the low-temperature constant condition for plastic compression molding.

Description

technical field [0001] The invention relates to the technical field of injection molding of automobile plastic parts, in particular to an automatic demoulding method applied to automobile plastic parts and an injection mold thereof. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise size. At present, in the existing injection molding methods, the heated and melted plastic is injected into the mold cavity by high pressure from the injection molding machine, and it is cooled and solidified. Then, a molded product is obtained; in this method, the temperature of the mold needs to be repeatedly raised and lowered during the production of injection molded parts to ensure that the injection material can be filled to any position in the mold cavity, which increases the energy consumption of the device during the production process. At the same time, for complex inject...

[0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. At present, in the existing injection molding method, the plastic melted by heat is injected into the mold cavity by high pressure from the injection molding machine, and it is cooled and solidified. Finally, molded products are obtained; in the process of producing injection molded parts, the temperature of the mold needs to be repeatedly raised and lowered to ensure that the injection molding material can be filled to any position in the mold cavity, which increases the energy consumption of the device during the production process. At the same time, for complex injection molded parts, the qualified rate of injection molded parts cannot be guaranteed, and the injection molded parts cannot be prevented from being affected by exhaust.
