Description

Technical Field

[0001] The present application relates to the field of injection molds, and in particular to a high-efficiency cooling two-color injection mold. Background Art

[0002] A two-color mold is a mold that uses two plastic materials to be molded on the same injection molding machine, and is molded twice, but the product is only ejected once. This molding process is also called double-material injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. Common two-color injection molds today are usually divided into three types: core rotary type, core retreat type, and push plate rotary type. Compared with traditional injection molding, two-color injection molds have the advantages of high precision of injection molding process and the ability to complete difficult injection molding processing.

[0003] Existing two-color injection molds are usually configured in dedicated injection molding machines, and the injection molds can be interchanged between different two-color injection molding machines. Usually, the processing process in the two-color injection mold is to inject one type of injection material, wait for it to cool and form, and then add another injection material, and finally eject the mold to complete the injection molding process. After that, the staff will perform post-processing such as grinding on the flash of the product produced by ejecting the mold to improve the quality of the injection molded product.

[0004] With regard to the above-mentioned existing injection molds, the inventors found that although the existing injection molds can complete the injection molding process in one demolding, they have the problem of low efficiency of segmented cooling. In actual production, it is necessary to wait for the completion of cooling once before performing subsequent processing, which takes up a considerable production time and reduces production efficiency. At the same time, after the processing is completed, the user also needs to perform certain processing on the flash generated by the mold produced by the injection molding, which further increases the production cycle of a single injection molding product and further reduces the molding efficiency of the mold.

[0032] In summary, the embodiment of the present application discloses a high-efficiency cooling two-color injection mold. When the user uses it, by turning on the external power supply of the two electric telescopic rods 218, the external upper box body 301 is pulled by the electric telescopic rods 218, so that the extrusion box body 302 is driven to move downward, so that the two extrusion box bodies 302 are movably embedded in the two lower molds 209, thereby realizing compression molding.
