When the mould is closed, the upper mould is pressed into the lower mould during the mould forming process.

[0003] The pressure applied by the upper mold to the lower mold when the mold is closed is the clamping pressure. When producing products of different materials and uses, the required clamping pressure is also different. When the mold clamping pressure is tested nowadays, a clamping machine is generally used to test the mold clamping pressure, which is too expensive. Therefore, a mold clamping pressure detection device is needed to solve the above problem. Utility Model Content
