Problems solved by technology

However, for polyethylene sheets with thinner thickness and larger length and width, because the water channel is far away from the working surface of the mold, the distribution is sparse and the length of the water channel is too long, the cooling water in the water channel heats up quickly, and the mold is cooled unevenly, which is easy to make The uneven shrinkage of the edge of the plate will cause warpage, which will affect the processing accuracy and product quality

Embodiment Construction

[0029] The following will further analyze the through-type cooling water channel ultra-high molecular weight polyethylene sheet forming mold according to the present invention according to the specific embodiments and the accompanying drawings.

[0030] combined with figure 1 , figure 2 As shown, the through-type cooling channel ultra-high molecular weight polyethylene sheet molding mold in this example includes a honeycomb structure support device 1 , an upper cooling device 2 , an upper mold 3 , a lower mold 4 , and a lower cooling device 5 . The upper surface of the lower mold 4 is provided with a chute 9, and the feeding device slides in the chute 9 to ensure that the high molecular weight polyethylene powder 6 is evenly laid on the bottom of the cavity of the lower mold 4 . The lower mold 4 is installed on the lower cooling device 5, the length and width of the lower cooling device 5 are the same as the bottom of the lower mold 4, and the wall thickness of the lower coo...

Abstract

The present invention discloses an ultra high molecular weight polyethylene (UHMWPE) sheet material forming die with through-type cooling water channels, and relates to the production technology of UHMWPE sheet materials. The forming die comprises a compression molding die, a cooling system and cellular structure support devices. The cooling water channels of the cooling system are in a rectangular thin-wall hollow structure and are supported by the cellular structure support devices, thereby making up for the deficiency of poor strength of the water channels. With adoption of the forming die, the area of the cooling water channels is increased, the forming die is uniformly heated, warping of edges of mold pressing plates is effectively removed, the quality of products is raised, and production continuity and reliability is guaranteed.

Description

technical field [0001] The invention relates to a production device and technology of an ultra-high molecular weight polyethylene sheet, in particular to a forming mold for an ultra-high molecular weight polyethylene sheet including a through-type cooling water channel device. Background technique [0002] Ultra-high molecular weight polyethylene is a thermoplastic engineering material. It combines the superior properties of most plastics, such as impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, and impact energy absorption. With the highest value, this new type of plastic product has been widely used in recent years and has a large demand. [0003] "Excellent performance, difficult processing" is a major feature of ultra-high molecular weight polyethylene, which is difficult to shape by conventional polymer processing methods. For sheet metal, the commonly used forming method is compression molding. After the...
