Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting molds, and particularly relates to a tensile separation device for die-casting molds. Background Art

[0002] The tensile separation device of a die-casting mold is a tool specifically designed for separating and disassembling die-casting mold components, especially for separating the moving mold and the stationary mold; firmly install the fixed fixture on the mold components to be separated to ensure no looseness between the fixture and the mold components. Connect one end of the pull rod to the fixed fixture and the other end to the lever, ensuring a firm connection. By rotating the operating handle, gradually increase the pulling force of the lever, so that the moving mold and the stationary mold of the mold are gradually separated. When the pulling force is sufficient, the mold components will be separated to complete the disassembly process. Due to the relatively small torque applied to the pull rod during the use of the tensile separation device in the related art, it cannot be effectively amplified to the output end, resulting in problems affecting the working efficiency and effect of the pull rod. And if the tensile separation device in the related art lacks guidance for the pull rod, it will cause problems such as deviation, bending or jamming of the pull rod during the working process, thus affecting the accuracy of the operation and the stability of the device.
