Embodiment Construction

[0017] A novel cooling duct sealing device installed on a hot stamping die according to the present invention will be further described below with reference to the accompanying drawings.

[0018] First, the sealing principle is explained, figure 1 , figure 2 , image 3 They are the structural diagrams and water leakage diagrams of three different sealing devices respectively, and the dotted lines in the figure are the water leakage routes. Such as figure 1 As shown, the pipe joint of the cooling pipe without a sealing ring is in direct contact with the mold interface, which requires extremely high matching precision between the two, and there is only one inflection in the leakage route, which is very prone to leakage problems; figure 2 As shown, the grooved single-seal cooling pipe is processed with a groove at the mold interface to place the seal ring, and the seal is achieved by pressing the seal ring. This sealing structure has a soft seal ring between the pipe joint a...

Abstract

The invention relates to a cooling pipe sealing device, and specifically relates to a novel hot stamping die cooling pipe sealing device. The novel hot stamping die cooling pipe sealing device comprises a water inlet and outlet pipe joint, a water inlet and outlet large seal ring, a water inlet and outlet small seal ring, an impurity filter screen, a flow rate detector and a special pipe joint ona die, wherein the sealing of the double seal ring structure is realized through the water inlet pipe joint and the pipe joint on the die, and the leakage of cooling water is prevented through multiple corners; a filter screen is installed at the joint of a pipe joint small thread and a die port, hard impurities are filtered under the condition that the flow rate of the cooling water is ensured tobe enough, so as to ensure the cooling effect and prolong the service life of the die; and the flow rate detector is installed at a water outlet to ensure that the condition that the die cannot be normally cooled due to pipe blockage and the like does not occur.

Description

technical field [0001] The patent of the present invention relates to a cooling pipeline sealing device, in particular to a cooling pipeline sealing device with double sealing rings installed on a hot stamping die. Background technique [0002] With the development of the economy, automobiles have entered thousands of households, but the ensuing environmental pollution has also attracted the attention of the national society. In order to solve this problem, the research and development of traditional automobile energy saving and emission reduction and new energy The mainstream development direction of the industry. Whether it is a traditional car or a new energy car, the lightweight of the body is very important. From the point of view of the traditional car, for every 100kg weight reduction of the car body, the fuel consumption per 100 kilometers can be reduced by about 1.5L, and the fuel utilization rate is also greatly improved; For new energy vehicles, the lightweight b...
