Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically a mold for producing thin-walled foot cups. Background Technology

[0002] Thin-walled stem cups are a common household item, generally made of glass or plastic. Existing plastic thin-walled stem cup molds typically consist of an upper mold, a middle mold, a lower mold, and a connecting shaft. The upper mold is a single piece used to fix the mold and can heat up when powered on. The upper mold has several flow channels, each with a flow hole for liquid flow. The middle mold has a complete set of stem molds and cup body molds. The lower mold is used to seal the middle mold. However, existing molds have the following problems: First, the single-piece upper mold design requires replacing the entire upper mold if the flow channels are damaged, which is not only wasteful of materials but also has high replacement costs and is cumbersome to process. Second, the middle mold is not convenient enough for the stem to be demolded, resulting in a slow demolding speed. Utility Model Content

[0003] In view of the defects of existing thin-walled foot cup molds, the technical problem to be solved by this utility model is to provide a thin-walled foot cup mold with a more reasonable upper mold design and convenient workpiece demolding.

[0004] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a thin-walled foot cup mold, comprising: an upper mold, a middle mold, a lower mold, and a connecting shaft.
