Mold pressing molding mold for toothpaste lid

Abstract

The invention relates to a mold pressing molding mold for a toothpaste lid, which comprises a lower mold and an upper mold. When the toothpaste lid is molded by the lower mold, a gap is formed between a lower mold cavity and a lower mold core cushion block, accordingly, the top edge of the toothpaste lid can be molded into a trimmed sharp shape, and the gap allows air bubbles in a molding cavity to pass through, so that the top edge of the toothpaste lid forms a trimmed sharp shape. After completion of mold pressing, in stripping, a friction wheel rotates by friction between external force and the friction wheel, and the friction wheel drives a mold head rotating sleeve to rotate; teeth on the mold head rotating sleeve are meshed with the molded toothpaste lid, accordingly, the toothpaste lid is stripped out of the molded lid mold head by rotating the toothpaste lid, so that internal threads of the toothpaste lid are protected, and are not damaged in stripping.

Description

Technical field: [0001] The invention relates to the technical field of bottle cap machines, in particular to a molding die for producing toothpaste caps. Background technique: [0002] Existing toothpaste caps are generally produced by injection molding. The disadvantages are: the production efficiency is low, the waste produced in the production process is large, and injection molding points will be generated on the product, which causes the product to be unattractive. [0003] Such as figure 1 As shown, for general bottle caps such as mineral water bottle caps, there is a mineral water bottle cap internal thread A1 formed on the inner wall of the mineral water bottle cap, so when the mineral water bottle cap is formed on the bottle cap machine, it can be formed in one go. The cap of the mineral water bottle is forcibly removed from the mold without damaging the inner thread of the cap of the mineral water bottle. There are customers who need to produce such as figure ...

Problems solved by technology

[0002] Existing toothpaste caps are generally produced by injection molding. The disadvantages are: the production efficiency is low, the waste generated in the production process is large, and injection molding points will be generated on the product, causing the product to be unattractive.

There are customers who need to produce such as figure 2 As shown in the toothpaste cap B, the inner wall of the toothpaste cap B is formed with the internal thread B1 of the toothpaste cap B and the ring teeth B2. The wall of the toothpaste cap B is thicker than that of the mineral water bottle cap, and the forced demoulding of the toothpaste cap B will damage the internal thread B1 of the toothpaste cap. At the same time, the top edge A2 of the mineral water bottle cap is rounded, while the top edge B3 of the toothpaste cap is sharp. , it is obvious that toothpaste caps cannot be processed by ordinary bottle cap production technology, so it is necessary to design toothpaste cap molds and improve ordinary bottle cap machines so that it can produce toothpaste caps
