Problems solved by technology

The existing molds for milk powder caps are usually injection-molded, and then manually labeled. Due to the error-prone manual operation, the defective rate of milk powder cap labeling is relatively high. The rear mold is ejected, and the ejection at the same time is likely to cause scratches (ejection marks) on the appearance of the product, which seriously affects the product quality

Embodiment Construction

[0024] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0025] Such as figure 1 , figure 2 As shown, a delayed ejection mold structure for realizing in-mold labeling of milk powder caps includes a front mold and a rear mold. The front mold and the rear mold are provided with a product cavity, and the finished product 1 of the milk powder cap obtained by injection molding is located on one side of the front mold The cover surface of the milk powder cover finished product 1 can be directly labeled, and the front mold includes a back plate 16, a supporting plate 9, a solid core plate 6, a push plate 5, a reset plate 17, a synchronous ejection mechanism and a delayed ejector arranged in sequence. One side of the solid core plate 6 is provided with a first core 4 and a second core 12, the other sid...

Abstract

The invention discloses a milk powder cover in-mold labeling delayed ejection mold structure. The structure comprises a cavity and a core. The cavity and the core are provided with product mold cavities. A finished milk powder cover product (1) obtained through injection molding is located on one side of the cavity. The cover surface of the finished milk powder cover product (1) can be directly labeled. The cavity comprises a backing plate (16), a supporting plate (9), a core fixing plate (6), a push plate (5), a return plate (17), a synchronous ejection mechanism and a delayed ejection mechanism. The synchronous ejection mechanism is composed of an oil cylinder (7), an ejector pin (3) and springs (8). The delayed ejection mechanism is composed of a delayed ejector rod (10), a delayed insert (15) and an ejector pin plate return rod (13). The milk powder cover in-mold labeling delayed ejection mold structure has the beneficial effects that in-mold labeling is realized; the reject ratio and labor cost caused by subsequent manual labeling are reduced; the appearance quality of products is optimized; and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a delayed ejection mold structure for realizing in-mold labeling of milk powder lids. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. The existing molds for milk powder caps are usually injection-molded, and then manually labeled. Due to the error-prone manual operation, the defective rate of milk powder cap labeling is relatively high. The ejection of the rear mold, and the ejection at the same time will easily cause scratches (ejection m...
