Problems solved by technology

[0003] However, the hydraulic drive has the following disadvantages: complex design, high production cost, poor follow-up production stability, occupying space, will increase the tonnage of the injection molding machine for mold production, complex control of the injection molding machine, increase the injection molding cycle, error-prone machine adjustment, injection molding cost will improve
However, the traditional mechanical drive slider has the problem of not being able to control the action sequence, and there has been no suitable method to overcome it for a long time

Abstract

The invention discloses an injection molding method of a double-color injection molding part and an injection mold. The injection mold is arranged on an injection molding machine and the working state of the injection mold can be controlled by the injection molding machine; the injection mold comprises a mechanical driving sliding mechanism which comprises a hard rubber sliding block assembly and a soft rubber sliding block assembly for forming, each of the hard rubber sliding block assembly and the soft rubber sliding block assembly comprises a sliding block body, a sliding block insert, a spring, a shifting block, a locking block, a first locator and a second locator. The injection mold adopts a mechanical sliding block to realize under cut, an oil cylinder is avoided, the mold size and the mold thickness can be effective reduced, a problem that a medium-small-tonnage double-color rotary injection molding machine cannot realize mold arrangement is solved, the control action of a mold-opening sliding block cylinder is removed, the forming period is shortened, the costs of the mold and the injection molding production are reduced, a problem that the traditional mechanical driving sliding block cannot control the action sequence is solved, and a situation that a multi-cavity double-color injection molding part is produced by a small injection molding machine can be realized.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an injection molding method for two-color injection molded parts and an injection mold implementing the method. Background technique [0002] Due to the requirements of appearance, function and cost, the internal structure of the existing two-color injection molded parts is becoming more and more complex, and more and more two-color injection molded parts are injected with two materials on the slider. But now there are mainly two driving modes of the slider mechanism: one is mechanical driving, and the other is hydraulic driving. The mechanical drive has the characteristics of simple design, low cost and good stability, while the hydraulic drive has a long stroke and is easy to control the action sequence of the slider. If two materials need to be injected on the slider, it is generally necessary to adopt a hydraulic drive design. [0003] However, the hydraulic driv...
