Novel double-color injection molding device

Abstract

The invention discloses a novel double-color injection molding device. The device comprises an injection molding device main body, a cooling device auxiliary water tank, a double-color injection molding transmission box and an injection molding cooling transmission box; the double-color injection molding transmission box is provided with a color mixing device, a color master batch raw material heating device, a color mixing device control gear set and a color mixing device support mechanism; a circulating water cooling device is provided with a first cooling water condensation pipe, a second cooling water condensation pipe, a first transmission traction wire, a first reverse water baffle plate, a reverse water outlet, a first transmission small pulley, a third cooling water condensation pipe, a second transmission traction wire, a first water inlet baffle plate and a second transmission small pulley; when equipment is used, a motor and a water pump of double-color injection molding equipment can be enlarged, and the ejecting and cooling speed is accelerated; meanwhile, the feeding speed can be accelerated through a large-diameter mixing spiral rod; and a series of work is synchronized for compound actions, so that the molding time is shortened, and the problem of easy generating weak stability of a rotating structure is improved.

Description

technical field [0001] The invention is a novel two-color injection molding device, which belongs to the field of two-color injection molding devices. Background technique [0002] Two-color injection molding is widely used in actual production. In the prior art, two-color injection molding is realized by two-color injection molding machines. The cost of two-color injection molding machines is much higher than that of ordinary injection molding machines, so this will bring certain benefits to enterprises economic pressure. [0003] Two-color injection molding technology is mainly used in the fields of home appliances, daily-use plastic products, and auto parts manufacturing. It is a new type of injection molding technology that can simplify the assembly process and improve the appearance of products. At present, the two-color mold structures used in the mold industry mainly include rotary table, Shaft type or its improvement. [0004] Among them, the turntable type rotatio...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of two-color injection molding device to solve the problem of using the prior art, because whether it is a rotating disc structure or a rotating shaft structure, it is carried out on a straight plane. Rotate 180° to realize the transposition of the mould; since the rotation is on a vertical plane, it is easy to have the problem of poor stability of the rotating structure, so it must be required that the repeated positioning accuracy after vertical rotation is high, and the required mold locking The force is large, the speed of simultaneous injection and feeding is not fast enough, and the follow-up cooling work is too long, which affects the cooling efficiency and delays the injection molding time.
