Description

TECHNICAL FIELD

[0001] The utility model relates to a mould technical field, concretely relates to a heat insulation structure of mould. BACKGROUND

[0002] SMC press mould is directly added with SMC sheet in open mould cavity, the mould is closed, SMC sheet becomes flow state and fills the cavity under the action of high temperature and pressure, and then the product is hardened and shaped under the condition of high temperature through chemical crosslinking.

[0003] Please see Figure 1 , the prior art SMC press mould usually includes lower mould 10 and the upper mould 20 used in cooperation with lower mould 10, the upper mould 20 includes upper mould body 21 and the upper mould pressing plate 23 set to the side of upper mould body 21 away from lower mould 10, and the heat insulation plate 50 is installed between the upper mould pressing plate 23 and the upper mould body 21. When the SMC press mould is installed, the upper mould pressing plate 23 is connected with the slider 200 of the hydraulic machine, and the lower mould 10 is installed on the workbench of the hydraulic machine. When in use, the slider 200 of the hydraulic machine drives the upper mould 20 of the SMC press mould to carry out the operation of closing, pressurizing and opening. In the SMC press mould, the heat insulation plate plays an important role. The heat insulation plate can effectively reduce the heat transfer between the mould and the outside world, reduce the heat loss, thereby reducing the energy consumption and improving the energy utilization efficiency. At the same time, the heat insulation plate can prevent the damage of high temperature to the mould elements (such as hydraulic oil cylinder, sealing ring, etc.), and prolong the service life.

[0004] In the prior art SMC press mould, the heat insulation plate 50 is installed between the upper mould body 21 and the upper mould pressing plate 23. When the slider 200 of the hydraulic machine drives the upper mould 20 of the SMC press mould to carry out the operation of closing and pressurizing, the pressure applied by the slider 200 of the hydraulic machine to the upper mould pressing plate 23 will be transmitted to the heat insulation plate 50, so that the heat insulation plate 50 is directly stressed. Since the heat insulation plate of the prior art is a glass fiber heat-resistant material composite plate, its mechanical strength is limited, and the heat insulation plate is directly stressed and prone to deformation. The deformation of the heat insulation plate will cause the unevenness of the mould, and the unevenness of the mould will easily cause the product to crack, the wall thickness to be uneven and the upper and lower moulds of the mould to shift during production. In addition, since the heat insulation plate in the prior art is installed below the upper mould pressing plate, when the deformed heat insulation plate needs to be replaced, the upper mould pressing plate needs to be disassembled first, and then the heat insulation plate can be disassembled and installed, so that the heat insulation plate is not convenient to assemble and disassemble.
