Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of molds, and in particular relates to a device for quickly replacing mold inserts. Background Art
[0002] The mold is installed on the injection molding machine to obtain various molds and tools for the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. The inserts of the mold play a role in positioning and supporting the product manufacturing process. In mold manufacturing, mold inserts are used to fix the position of the mold to ensure the accuracy and stability of the position of the product during processing. By using mold inserts, the workpieces in the manufacturing process can be accurately positioned and fixed, thereby ensuring the quality and precision of the product. During the production process of the mold, different inserts need to be replaced for different products. The operator needs to lift the mold from the injection molding machine, disassemble the mold offline, and replace the inserts. This greatly wastes production time and causes the machine to be idle for a longer time. There are certain operational safety risks in the process of transportation, mold turning, opening, disassembly and assembly of the mold, especially for medium and large molds. The mold is difficult to open due to its own weight, structure and other reasons, and there is a risk of damaging the precision parts in the mold. The operation requires injection molding workers, fitters, etc. to complete together, and the threshold of technical professional fields is high. Utility Model Content

[0016] In order to better understand the purpose, structure and function of the present invention, a device for quickly replacing mold inserts of the present invention is further described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1-3 As shown, a device for quickly replacing a mold insert of the utility model comprises a mold frame 3, an insert 2 is provided in the mold frame 3, an insert 2 is provided in the insert 2 4, the insert 1 2 is fixedly arranged, the insert 2 4 is movably arranged, and can be replaced according to different product requirements, there is a gap between the mold frame 3 and the insert 1 2, there is a pry bar mechanism in the gap, and the pry bar mechanism is used to pry up the insert 2 4.
[0018] The pry bar mechanism includes a support column 5, a connecting rod 6 and a fixed pressure plate 8. The connecting rod 6 passes through the support column 5, and the front end abuts against the bottom of the insert 2 4. The connecting rod 6 and the support column 5 are interference fit to prevent the connecting rod 6 from falling. The support column 5 is fixedly installed at the bottom of the insert 2 4 through the fixed pressure plate 8. Specifically, the fixed pressure plate 8 is fixedly connected to the bottom of the support column 5. The two ends of the fixed pressure plate 8 have mounting holes.
