Problems solved by technology

[0002] With the development of the molding industry, technology continues to innovate. For this type of mask products, the traditional production method is realized by glue and double-sided tape. There are many other accessories, which are prone to poor product quality, such as (glue residue. Paste Not firm. Position deviation, etc.), resulting in high product cost, complicated production, and poor service life of the product. The prefabricated parts and the secondary molded products are pasted together by manpower. If there is glue in the pasting process Remains or pasting is not firm. Misalignment will affect the quality of the product and cause waste of manpower and material resources

Abstract

The invention discloses an embedded-type secondary injection mold which comprises an upper mold, a lower mold and a mold core; an inner cavity in the mold core is provided with a pre-manufactured element which is arranged in the inner cavity of the mold core in an embedded manner; the mold core is also internally provided with a secondary injection mold channel; and a material inlet of the secondary injection mold channel is formed below the pre-manufactured element, and the pre-manufactured element is provided with a slot for feeding materials. According to the embedded-type secondary injection mold, through changing a mold mechanism, the product quality is improved, and the labor cost and the resource cost are also lowered greatly.

Description

technical field [0001] The invention relates to the field of mold design, in particular to an embedded secondary injection mold. Background technique [0002] With the development of the molding industry, technology continues to innovate. For this type of mask products, the traditional production method is realized by glue and double-sided tape. There are many other accessories, which are prone to poor product quality, such as (glue residue. Paste Not firm. Position deviation, etc.), resulting in high product cost, complicated production, and poor service life of the product. The prefabricated parts and the secondary molded products are pasted together by manpower. If there is glue in the pasting process Remains or pasting is not firm or offset, which will affect the quality of the product and cause a waste of manpower and material resources. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an embedded secondary inj...
