Problems solved by technology

[0002] Ceramic knives have the advantages of wear resistance, high density, high hardness, no capillary pores, no dirt, non-metallic casting will not rust, no metal smell residue when cutting food, thin and sharp, easy to hold and cut, easy to clean, etc. , has many characteristics that cannot be replaced by metal knives. With the reduction of the production cost of ceramic knives, ceramic knives are rapidly entering people's daily life. At present, there are many types of ceramic knives on the market. The ceramic blades of ceramic knives and The connection of the handle is usually to install the ceramic blade on the handle. When assembling, the handle of the ceramic blade is inserted into the slot hole reserved on the handle that matches the handle of the ceramic blade, and then the handle of the ceramic blade is glued to the handle with glue. Firm, this method has been used for a long time, which will easily lead to loosening of the ceramic blade; there are also one-time injection molding of the ceramic blade and the handle, but this method is easy to shrink due to the plastic during the injection molding process, resulting in uneven surface of the handle. Defects affect the beauty of the knife. In addition, the ceramic knife handle has a single style, usually one color, and the appearance is not beautiful enough to meet people's diverse needs for ceramic knives.

Embodiment Construction

[0020] Such as figure 1 , figure 2 with image 3 As shown, a multilayer injection molded ceramic knife includes a ceramic blade 1 and a handle 2, the ceramic blade includes a handle 12 and a blade 11, and the handle is integrally formed with the handle at least twice to form a multilayer structure , In this way, through multiple injections, defects on the surface of the tool handle caused by injection shrinkage can be reduced, which affects the appearance and feel of the tool.

[0021] Preferably, the handle is integrally formed with the handle by two injection moldings to form a double-layer structure. In this way, two injection moldings can reduce the surface defects of the tool handle and reduce injection molding costs.

[0022] Preferably, the double-layer structure includes an inner layer 22 and an outer layer 21, the inner layer covers the handle, and the outer layer partially covers the inner layer. In this way, as required, The handle is first injection molded into...

Abstract

The invention discloses a multilayer injection molding ceramic cutting tool. The multilayer injection molding ceramic cutting tool comprises a ceramic tool blade and a hand shank, wherein the ceramic tool blade comprises a shank portion and a blade portion, and the hand shank is molded through at least two times of injection molding, is integrally molded with the shank portion, and is of multilayer structure. Besides inherent characteristics of a ceramic cutting tool, the multilayer injection molding ceramic cutting tool further has the advantages of being simple in structure, smooth in surface, glossy, difficult to loosen due to the fact that the ceramic tool blade and the hand shank are designed in integration mode and the like.
