Clamp for machining mold insert

Abstract

The invention relates to the field of molds, in particular to a clamp for machining a mold insert. The clamp comprises a base, two air cylinders and sliding rods driven by the air cylinders to slide correspondingly are arranged on the base, clamping blocks are arranged at the end parts, deviating from the air cylinders, of the sliding rods and are used for clamping the insert, the base is provided with a driving mechanism and a supporting block driven by the driving mechanism to ascend and descend, the supporting block is used for making contact with the bottom surface of the insert, the driving mechanism comprises a main shaft arranged on the base in a rotating mode, a crank is fixed to the main shaft, an eccentric shaft is fixed to the end part, deviating from the main shaft, of the crank and is sleeved with a rotating sleeve, a connecting rod is fixed to the rotating sleeve, and the end part, deviating from the rotating sleeve, of the connecting rod is hinged to the supporting block. According to the clamp, the insert can be turned over without loosening the clamp, the clamp does not need to be operated to clamp the insert after the insert is turned over, convenience is achieved, and therefore the efficiency is improved; the bottom surface of the insert can be stably supported, and the clamping blocks are not liable to hindering machining of the top surface of the insert; and when the main shaft rotates, rotation of the clamping blocks and the insert can be automatically completed, and the automation degree is high.

Description

technical field [0001] The present application relates to the field of molds, in particular to a fixture for processing mold inserts. Background technique [0002] In the mold, the insert refers to the mold accessories used to be embedded in the mold, which plays the role of fixing the template and filling the space between the templates. When the mold often needs to be modified, inserts can be added to the modified mold in advance. When the mold is changed in the future, only the inserts need to be replaced, and even several spare parts of the inserts can be made for replacement when the mold is opened, which is convenient for mold modification. For the processing of mold inserts, it is necessary to clamp them with fixtures for processing. [0003] In view of the above-mentioned related technologies, the inventor believes that some inserts need to be processed on both sides. When the insert is to be turned over, it is necessary to loosen the clamp, manually turn over the i...

[0003] In view of the above-mentioned related technologies, the inventor believes that some inserts need to be processed on both sides. When the insert is to be turned over, it is necessary to loosen the clamp, manually turn over the insert, and then operate the clamp to clamp the insert, which is inconvenient.
