Embodiment Construction
[0034] like Figure 1-Figure 4 As shown, a production process method for continuous extrusion of three-dimensional hollow product molding has the following steps:
[0035] 1) Carrying out miscible mastication of the raw material, the raw material is PVC, and the temperature of the raw material after the miscible mastication is 150-180° C.;
[0036] 2) The raw material through mixing and masticating is extruded through at least one die 111 of a transverse extruder, and is closely combined with the roll surface of the transverse roll 12 to form a transverse strip 112. The temperature of the die 111 of the transverse extruder is 175°C;
[0037] 3) Extrude the raw materials that have been mixed and masticated through at least one die 131 of a longitudinal extruder to form a longitudinal strip 132, and the temperature of the die 131 of the longitudinal extruder is 175° C.;
[0038] 4) The longitudinal strips 132 and the transverse strips 112 are roll-formed, and cooled, cut, and ...

The invention discloses a production technology method and equipment for molding a three-dimensional hollow product in a continuous extruding manner. The method comprises the following steps: raw materials are subjected to mixing and dissolving as well as plastifying; the raw materials after mixing and dissolving as well as plastifying are extruded out through a mouth mold of at least one transverse extruder, and the extruded raw materials are tightly combined with a roll surface of a transverse roll to form a transverse strip; the raw materials after mixing and dissolving as well as plastifying are extruded out through a mouth mold of at least one longitudinal extruder to form a longitudinal strip; the longitudinal strip and the transverse strip are subjected to roll forming, and the roll formed product is cooled, cut and wound to obtain the three-dimensional hollow product. The invention further discloses equipment for molding the three-dimensional hollow product in a continuous extruding manner. The three-dimensional hollow product is made through the combination between the self thermal viscosity of thermoplast and the equipment for molding the three-dimensional hollow product in a continuous extruding manner; strip-shaped plastic of different shapes and colors is respectively manufactured on the transverse roll and a longitudinal roll by the at least one transverse extruder and the at least one longitudinal extruder, and three-dimensional hollow products of the same colors or different colors are molded, and the three-dimensional hollow product can be produced continuously.
Description
technical field [0001] The invention relates to the field of thermoplastic molding, in particular to a production process and equipment for continuously extruding three-dimensional hollow product molding. Background technique [0002] At present, the three-dimensional through-hole products produced by the plastics industry can only be formed by injection and secondary heating or adhesive technology. Injection molding can only form products with a limited area, and then reassemble one by one. The secondary heating or adhesive combination is processed into strips first and then processed again. The above two methods have the disadvantages of low production efficiency, poor quality, high energy consumption, and large labor costs. Contents of the invention [0003] According to the technical problems of low production efficiency, poor quality, high energy consumption, and large labor costs in the prior art proposed above, a production process and equipment for continuous extr...
