Automatic sprue cutting-away and grinding equipment for digital device shell injection molding

Abstract

The invention discloses automatic sprue cutting-away and grinding equipment for digital device shell injection molding, and belongs to the field of digital device production and manufacturing. The equipment comprises a base, a sprue cutting-away device fixed to the base, and a grinding device fixed to the base. An automatic feeding device used for conveying products is also arranged on the base. The automatic feeding device is provided with a product positioning base used for positioning the products. The sprue cutting-away device and the grinding device are arranged in sequence in the conveying direction of the automatic feeding device. The grinding device is fixed to the base through a grinding feeding mechanism. The equipment further comprises a product taking and placing device which is fixed to the grinding feeding mechanism. According to the automatic sprue cutting-away and grinding equipment for digital device shell injection molding, a sprue formed after digital device shell injection molding is completed can be automatically cut away and ground, mechanical and automatic production is achieved, the product quality is improved, the labor cost is greatly reduced, and the production cost of a digital device shell is reduced.

Description

[0001] technical field [0002] The invention relates to the field of digital equipment production and manufacturing, in particular to an automatic gate cutting and grinding equipment used for injection molding of digital housings. Background technique [0003] Injection molding is a method in which heat-melted materials are injected into a mold cavity by high pressure, and after cooling and solidification, molded products are obtained. This method is mainly suitable for processing plastic products. Usually, after the plastic product is out of the mold, there is a gate left in the flow of the injection port, and the gate needs to be cut off after the injection molding is completed; in some occasions where the surface quality is relatively high, it is generally necessary to Grinding to improve the appearance and surface quality of the product. The traditional method of cutting the gate and grinding is to cut it manually with gate pliers or blades. When grinding with a file...

Problems solved by technology

Usually, after the plastic product is out of the mold, there is a gate left in the flow of the injection port, and the gate needs to be cut off after the injection molding is completed; in some occasions where the surface quality is relatively high, it is generally necessary to Grinding to improve the appearance and surface quality of the product. The traditional method of cutting the gate and grinding is to cut it manually with gate pliers or blades. When grinding with a file but using manual operation, there are the following shortcomings: (1) Manual cutting is easy to accidentally injure product, making the quality of the product unstable; (2) the efficiency of manual removal is low, requiring a large number of operators, which not only increases the production cost, but also increases the labor intensity of the operators; (3) the use of manual removal is due to It is necessary to use sprue pliers or blades, and it is easy for operators to cut their fingers during work, especially after a long time of work; (4) It is difficult to control the grinding depth by manual grinding, and it is easy to grind the arc surface, lead to product scrapping

However, it does not have the function of automatic grinding, and it is necessary to manually put the product to be cut into the gate cutting device to complete the gate cutting action. Therefore, it requires labor and does not realize the complete automation of gate cutting
