Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.

Description
translated from Chinese
【技术领域】 【Technical field】
本发明涉及一种玻璃置入模具注塑成型方法及其产品，特别涉及一种玻璃置入模具注塑成型热塑性材料及热塑性弹性体的方法及其得到的产品。The invention relates to a method of inserting glass into a mold for injection molding and its products, in particular to a method of inserting glass into a mold for injection molding thermoplastic materials and thermoplastic elastomers and the products obtained therefrom.
【背景技术】 【Background technique】
目前消费性电子产品在外观设计上不断推陈出新，玻璃已逐渐成为机构件的一部分。随着触控手机、平板电脑及笔记本电脑触控趋势的兴起，玻璃以自身的质感佳等优点，应用越来越广泛，且深受消费者喜爱。At present, the appearance design of consumer electronic products is constantly being innovated, and glass has gradually become a part of mechanical components. With the rise of touch-control trends in mobile phones, tablet PCs, and notebook computers, glass has become more and more widely used due to its good texture and other advantages, and is deeply loved by consumers.
然而，普通玻璃由于不易弯折或者因为侧边有微小缺口时受到冲击，而导致玻璃容易碎裂。通常制造厂商为了保证玻璃不破碎而采用改良过的玻璃，改良过的玻璃虽然抗冲击强度强于普通玻璃，但其价格相对昂贵，为普通玻璃的数倍，使产品提高了成本。However, ordinary glass is easy to shatter because it is not easy to bend or because it is impacted when there is a small notch on the side. Usually manufacturers use improved glass to ensure that the glass does not break. Although the impact strength of improved glass is stronger than that of ordinary glass, its price is relatively expensive, which is several times that of ordinary glass, which increases the cost of the product.
同时，在厚度为1.0mm以下的薄形玻璃上注塑热塑性材料时，当玻璃尺寸越大，而进胶点数量少，且所注塑的塑料也是薄件的情况下，则射出压力相对需提高，才能使热塑性材料充填饱整个模腔。然而，此射出压力的提高会导致薄形玻璃的破裂。At the same time, when injecting thermoplastic materials on thin glass with a thickness of less than 1.0mm, when the size of the glass is larger, the number of glue points is small, and the plastic to be injected is also thin, the injection pressure needs to be increased relatively. In order to make the thermoplastic material fill the entire cavity. However, this increase in injection pressure can lead to breakage of the thin glass.
有鉴于此，实有必要开发一种玻璃置入模具注塑成型方法，该方法能够使玻璃不易破碎，并保证有足够的卡勾或卡扣在组装时能够良好结合。In view of this, it is necessary to develop an injection molding method for inserting glass into a mold, which can make the glass not easily broken and ensure that there are enough hooks or buckles that can be well combined during assembly.
