Embodiment Construction
[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, as those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0036] This grinding wheel die is mainly used in the production of resin grinding wheels with ultra-thick diamond layers.
[0037] like figure 1 and figure 2 As shown, the resin grinding wheel mold includes a mold frame 1, a first upper pressing ring 2, a second upper pressing ring 12, a lower pressing ring 3, an upper core type 4, a lower core type 5, an upper core type 4, a ...

The invention belongs to the technical field of grinding wheel manufacturing, and in particular relates to a resin grinding wheel mold and a pressing method thereof. The resin grinding wheel mold includes a mold frame, a first upper pressure ring, a second upper pressure ring, a lower pressure ring, an upper core type, a lower core type and a fixed tooling. The mold frame is a hollow ring structure; the upper core type and the lower core type are both hollow ring structures; the lower pressure ring is a ring structure; the first upper pressure ring is an inverted "L" ring The structure is used for taking out after the first pressing; the second upper pressing ring is a ring structure and is used for the second pressing. In the grinding wheel mold of the present invention, the diamond layer of the grinding wheel is pressed and formed twice, and then solidified as a whole, which can directly press the resin grinding wheel with an ultra-thick diamond layer, improve the quality of such grinding wheels, increase production efficiency and production pass rate.
Description
technical field [0001] The invention belongs to the technical field of grinding wheel manufacturing, and particularly relates to a resin grinding wheel mold and a pressing method thereof. Background technique [0002] In the production of grinding wheels, the diamond layer is formed from solid powder by heating and pressure. In this process, a mold is used, and the mold ensures the shape and product quality of the grinding wheel. The gold layer of some grinding wheels is too thick. When using conventional grinding wheel molds to press, it is easy to cause uneven feeding, difficult to flatten the pressure ring, and uneven force on the upper and lower diamond layers, resulting in unqualified quality of the finished grinding wheel. [0003] At present, most of the grinding wheels with ultra-thick diamond layers are pressed in a combination method, that is, the grinding wheel is divided into two grinding wheels with half the thickness of the diamond layer for pressing, and then ...
