Positive and negative pressure moulding die

Abstract

The invention discloses a positive and negative pressure moulding die. The positive and negative pressure moulding die is characterized by comprising an upper die and a lower die, wherein the lower die comprises a carrying table, slide modules arranged just below the carrying table, and a rolling shaft, wherein a rotary shaft carrying out fixed autorotation is arranged at a centre below the carrying table; a drive module and a guide block are connected to the two ends of each slide module respectively; slide guide rails are arranged at the bottoms of the two slide modules; the two guide blocks are located above and below the rotary shaft respectively, and roll on the rotary shaft; the top of each slide module is configured to be a slope surface which sequentially comprises a first slope surface and a second slope surface; and each first slope surface is close to the corresponding guide block, and each second slope surface is close to the corresponding drive module. According to the positive and negative pressure moulding die disclosed by the invention, a cutting action is more stable during a running process of the whole device, and cutting efficiency is higher through configuring the top surface of each slide module to be the slope surface; and meanwhile, the device is capable of further improving stability by virtue of the guide blocks, and effectively controlling the relative movement of the slide modules at the two sides, thus increasing the production efficiency.

Description

technical field [0001] The invention relates to a plastic molding device, in particular to a positive and negative pressure molding die. Background technique [0002] At present, in the production and cutting process of plastic products, because the material itself is relatively soft, it needs to be cut quickly and the whole process should be kept stable. Once trembling occurs, the cutting result may be unsatisfactory. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a positive and negative pressure molding die, which can provide [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A positive and negative pressure forming mold, characterized in that it includes an upper mold and a lower mold; the lower mold includes a carrier, a sliding module and a cutting module arranged directly under the carrier; the center below t...
