Problems solved by technology

However, with the development of electronic products such as mobile phones, some products have higher requirements on the surface, especially some transparent products, which require that there are no gate marks on both sides of the product, and its particularity causes some products to be designed with side pouring. For some products, due to the special requirements of product raw materials and structures, such as thin sheet structure, point pouring cannot satisfy the complete filling of plastics, while direct pouring must carry out the above-mentioned post-stage waste cutting process

Embodiment Construction

[0013] The preferred embodiments are listed below to illustrate the structure of the injection mold for automatically cutting waste.

[0014] See figure 1 , a preferred embodiment of the present invention discloses an injection molding mold for automatically cutting waste, which mainly includes a fixed mold 1, a fixed template 2, a movable mold 3, a movable template 4, a mold foot 5, a material cutting mechanism 6 and an ejector Institution7. Among them, the fixed mold 1 and the movable mold 3 are aligned and matched through the guide rod 8, and the material cutting mechanism 6 is used to advance the product 91 ( image 3 Reference) and the waste material 93 at the runner 92 ( image 3 Refer to) automatic cutting and separation, the ejector mechanism 7 moves between the mold feet 5, and is used to eject the waste 93 at the product 91 and the runner 92 after the mold is opened.

[0015] One surface of the fixed mold 1 is provided with a plurality of profile surfaces 10 corre...

Abstract

This invention discloses an injection molded die for automatically cutting scraps used in producing injection products including a fixed mold, a moving mold and a cutting unit, in which, said fixed mold is matched with the moving mold to form a cavity corresponding to the injection product and a runner conducting to the fixed mold or the moving mold, said cutting unit includes a cutting plate set close to the cavity and extending into the runner after molding a product to cut the scraps connected with the product along the edge of the cavity, said die can cut the scraps in the runner and separates them from the product by the cutting unit before the product is finished and taken out so as to avoid separating products from runners artificially to reduce production time and cost.

Description

【Technical field】 [0001] The invention relates to an injection molding mold, in particular to an injection molding mold capable of automatically cutting waste materials. 【Background technique】 [0002] The plastic process is usually that plastic particles are heated to a fluid state and molded into the desired product by injection technology with the help of a mold. Because plastic is easy to shape, light in weight, rich in color, beautiful and applicable, it has been widely used in electronics, automobiles, motors, electrical appliances, instruments, meters, home appliances and communications. Its application fields are expanding continuously, and molds are used to produce plastic products important equipment. The development of molds is directly related to the development of the plastics industry. [0003] When using an injection molding machine to manufacture products, the mold used must be based on the designed product shape and size. Multiple cavities corresponding to...
