Packaging mold structure and its products

This creation is related to a mold, especially a package mold structure and its products.

According to the conventional packaging mold for LED, it mainly has a glue injection port, and a plurality of gates are connected to the outside by the glue injection port, and the gates are connected by a plurality of gates. hole. When the sealant plastic is injected into the glue injection port, the sealant plastic can be guided into each cavity through each runner to complete the LED packaging operation.

However, since the package mold is often formed by the upper and lower molds being closed, a gap is easily formed between the mold clamping surfaces to cause the overflowed rubber to form a residual glue, so that the residual glue remains on the finished product. In some processes such as LED packaging, if the residual glue is brought to the subsequent processing equipment by the finished product, the residual glue may be affected when the residual glue and the finished product fall off due to factors such as vibration or collision. The operational accuracy of the processing equipment, and even serious problems such as the machine crash or misjudgment. In order to solve this problem, in the past, the packaged finished product must pass through a glue removing operation procedure, that is, scraping the residual glue on the finished product by manual means, so as to avoid the residual glue being brought into the subsequent process by the finished product, thereby causing the above problem. .

However, due to the scraping of the residual glue, it is not possible to ensure that the residual glue on each finished product is removed. Especially for small-sized packaged products such as LEDs, it is inevitable that residual glue remains on the finished product, and the residual glue is often irregular shape and partial size, which is difficult to cut or scrape off when it is broken. Effectively ensuring that the residual glue of the finished product is removed, so that it is still possible to cause the residual glue to be carried to the subsequent processing equipment along with the finished product.

In view of this, the creator is trying to improve and solve the above-mentioned shortcomings, and he has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The main purpose of the present invention is to provide a package mold structure and a product thereof, which are formed by the design of the package mold, so that the residual glue can be formed on the package mold and can be effectively removed by cutting or the like; since the package mold is deliberately made The residual glue is formed as part of the glue filling, so the residual glue has a certain shape and is located at a specific position, so it can be effectively removed by cutting or the like, so as to avoid the residual glue remaining on the packaged product.
