Description

Technical Field

[0001] This utility model relates to the field of embossing machine technology, and in particular to an embossing machine for the inner drum of a washing machine. Background Technology

[0002] Washing machines are cleaning appliances that use electrical energy to generate mechanical action to wash clothes. They are divided into two categories according to their rated washing capacity: household and commercial.

[0003] The inner drum of a washing machine is one of the important components of a washing machine. Currently, the production process of washing machine inner drums requires an embossing process. Chinese Patent Application No. 201822142194.5 discloses a pattern forming machine for a washing machine inner drum, including a worktable with multiple identical concave and convex mold groups spaced at intervals along its upper surface. Each concave and convex mold group consists of a cooperating concave mold assembly and a convex mold assembly. The outer side of the concave mold assembly is connected to the output end of a hydraulic cylinder, and the inner side of the convex mold assembly is connected to an inner support mechanism. The inner support mechanism includes a support shaft mounted at the center of the worktable, on which a support block is mounted. The support block consists of a concave block in the middle and convex blocks extending axially at both ends of the concave block. The sides of both convex blocks extend radially outward to form raised ends, forming an inclined surface axially. The bottom end of the support shaft is connected to a drive device. The convex mold assembly includes a first inner support block, the inner side of which has a groove that cooperates with the concave block and the convex blocks. Although the aforementioned patterns on the inner drum of the washing machine can be pressed out, the structure is quite complex and requires three sets of molds, which greatly increases the equipment cost. Therefore, a solution is urgently needed. Utility Model Content

After the embossing is completed, the clamping assembly releases the workpiece, the pressing cylinder 20 drives the pressing plate 19 to press against the workpiece, and the supporting cylinder 22 drives the supporting plate 21 to support the bottom of the workpiece. Then, the lifting motor drives the material pick-up frame 18 to move upward, making it easier for the worker to pick up the material. This utility model has a simple structure. It only requires one set of embossing molds to achieve three-sided embossing of the washing machine inner drum, which greatly reduces the cost. Moreover, by setting up the material pick-up assembly, it is easy to pick up and put away the embossed product, making it easy to operate.
