Problems solved by technology

[0003] In the production process of two-color injection molding, two different raw materials need to be melted and then injected into the mold for cooling and molding, and the molding efficiency itself is not high.
In addition, when the molten raw material is cooled, it relies on the cooling water circuit inside the mold for heat dissipation and cooling, while the traditional cooling water is driven by water delivery equipment such as water pumps, which not only consumes electric energy but also generates heat when it is working, and the heat dissipation effect is not ideal. Long cooling time, therefore, the molding efficiency of existing two-color injection molding products is often relatively low

Embodiment 1

[0028] refer to Figure 1-2 , a two-color injection molding process based on a self-cooling injection molding machine, including the following steps:

[0029] S1, feeding, put the dried two raw materials into the two hoppers of the two-color injection molding machine respectively;

[0030] S2, material feeding, start the two-color injection molding machine, the two feeding cylinders in the two-color injection molding machine respectively convey two kinds of raw materials, and the feeding cylinders heat the raw materials to a molten state at the same time;

[0031] S3, injection, control the output of molten raw materials through the nozzle in the two-color injection molding machine, and inject the two raw materials into different molding grooves in the mold in turn;

[0032] S4, cooling molding, the cooling water channel in the two-color injection molding machine continuously dissipates the internal heat, and the molten raw materials in the mold are gradually cooled and forme...

Embodiment 2

[0048] refer to Figure 3-4 , different from Embodiment 1, the inner top of the liquid storage cylinder 11 is rotatably connected with a steam turbine 15, and the blades of the steam turbine 15 can be made into a wind cup shape, so that the evaporated liquid flow blown in can push the steam turbine 15 Rotate, and the lower end of the steam wheel 15 is fixedly connected with a spoiler 16 coaxially.

[0049] In this embodiment, when the vaporized evaporating liquid flows into the liquid storage cylinder 11 along the one-way inlet pipe 12, it can blow the steam turbine 15 to rotate, and drive the spoiler 16 coaxially arranged with the steam turbine 15 to rotate together, which can The evaporating liquid in the liquid storage cylinder 11 is stirred to quickly dissipate the heat contained in the evaporating liquid through the liquid storage cylinder 11 with good heat conduction, thereby improving the working efficiency of the device.

Abstract

The invention discloses a double-shot molding technology based on a self-cooling type injection molding machine. The double-shot molding technology based on the self-cooling type injection molding machine comprises the following steps of S1, material placement; S2, material conveying operation; S3, material injection; S4, cooling forming operation, specifically, the internal heat is continuously emitted by a cooling water channel in the double-shot injection molding machine, and molten raw materials in a mold are gradually cooled and formed; and S5, material taking operation, specifically, theS3 and the S4 continues to be carried out. The double-shot injection molding machine used in a double-shot molding forming method comprises a base. An injection molding facility is installed at the upper end of the base, and an outer cover body is further installed at the upper end of the base. A forming mechanism is arranged in the outer cover body, and a first liquid storage groove and a secondliquid storage groove are formed in the side wall of the outer cover body. According to the double-shot molding technology based on the self-cooling type injection molding machine, a driving device can operate through a large amount of heat generated in the injection molding process, and therefore cooling liquid in the second liquid storage groove can circularly flow in condensation pipes, a large amount of electric energy consumption can be reduced, rapid cooling forming operation of the molten raw materials can be promoted, and the processing efficiency of double-shot molding products is improved.

Description

technical field [0001] The invention relates to the technical field of two-color injection molding equipment, in particular to a two-color injection molding process based on a self-cooling injection molding machine. Background technique [0002] Two-color injection molding refers to a molding process in which two different materials are injected into the same set of molds, so that the injection molded parts are formed from two materials. [0003] In the production process of two-color injection molding, two different raw materials need to be melted and then injected into the mold for cooling and molding, and the molding efficiency itself is not high. In addition, when the molten raw material is cooled, it relies on the cooling water circuit inside the mold for heat dissipation and cooling, while the traditional cooling water is driven by water delivery equipment such as water pumps, which not only consumes electric energy but also generates heat when it is working, and the h...
