Embodiment Construction

[0020] A high-strength ultra-thin carbon fiber mold, see Figure 1 ~ Figure 3 : It includes a female mold part and a male mold part. The female mold part and the male mold part are combined to form a cavity 1. The cavity 1 is an ultra-thin carbon fiber product. The upper part of the cavity 1 is the female mold part and the lower part is the male mold part. , the female mold part includes the female template 2, the female mold core 3, the male mold part includes the male template 4, the male mold core 5, the hot runner nozzle 6, the hot runner nozzle 6 is connected to the cavity 1 from bottom to top, and the male mold core 5 Corresponding to the final feeding position of the filler in the cavity 1, at least one exhaust inlet 7 is provided. The upper end surface of the exhaust inlet 7 is recessed with exhaust grooves 8 communicating with each other. hole 9, the upper end of the through hole 9 is connected to one of any exhaust grooves 8, and the inside of the female mold core 3 ...

Abstract

The invention provides a high-strength ultrathin carbon fiber die. By means of the high-strength ultrathin carbon fiber die, products are outstanding in exhaust, the die is stable in temperature, the injection molding period is short, and automatic production of the die can be achieved on an electric high-speed machine. The high-strength ultrathin carbon fiber die comprises a female die portion and a male die portion. The middle of the female die portion and the middle of the male die portion are combined to form a cavity. An ultrathin carbon fiber product is arranged in the cavity. The female die portion is arranged on the upper portion of the cavity, and the male die portion is arranged on the lower portion of the cavity. The female die portion comprises a female die plate and a female die kernel. The male die portion comprises a male die plate, a male die kernel and hot runner nozzles. The high-strength ultrathin carbon fiber die is characterized in that the hot runner nozzles penetrate through the cavity from the bottom to the top; at least one exhaust insert is formed at the final filler feeding position, corresponding to the cavity, of the male die kernel; exhaust grooves which are mutually communicated are formed in the upper end faces of the exhaust inserts in a concave mode, through holes are formed in the exhaust inserts, and the upper ends of the through holes are connected with any exhaust groove; a plurality of female die kernel steam holes are formed inside the female die kernel.

Description

technical field [0001] The invention relates to the technical field of mold structures, in particular to a high-strength ultra-thin carbon fiber mold. Background technique [0002] The weight of carbon fiber is only one-third of that of aluminum alloy, but its impact resistance is twice that of aluminum alloy. The heat dissipation effect is the best among the materials currently used. Shielding effect. Due to the nature of its special materials, it has not been widely used in consumer electronics in the past few years. [0003] The shell of PC+carbon fiber is not as easy to mold as ordinary engineering plastics, and the requirements for the mold are relatively high, and the mold temperature is required to be kept constant at about 150 degrees. This type of plastic material has poor exhaust, and various problems are prone to occur when the mold is mass-produced. The injection molding cycle of the mold is long and the cost is too high. Contents of the invention [0004] I...
