Abstract
The utility model discloses a novel sand wheel mold with a combined mold core, consisting of a mold ring, an upper mold, a lower mold and the mold core, wherein the mold core is arranged in the upper mold and a central hole of the lower mold; and the mold core is of a split type structure and consists of a mold core block I, a mold core block II and a mold core block III. The novel sand wheel mold is characterized in that the combined hollow mold core is arranged in the lower mold and a central hole of the upper mold, so that when a sand wheel is manufactured under high pressure, the demolding is convenient in the demolding process; and the mold core block I is firstly released, and then the mold core block II and the mold core block III are released so as to be more beneficial to demolding. Simultaneously, according to the novel sand wheel mold, the service lives of the mold ring and the mold core are longer; and the cost of the manufacturing mold is low, and the service life of the whole sand wheel mold can be improved, so that the cost for producing the sand wheel is reduced.
Description
Technical field
The utility model relates to a kind of mould of making emery wheel, is specifically related to a kind of grinding wheel die of novel combination shape core rod.
Background technology
Emery wheel is a kind of common machining mould, and it can be roughly ground and half correct grinding the cylindrical of metalwork or nonmetal parts, interior circle, plane and various profile when rotating at a high speed.Emery wheel generally is to process through grinding wheel die, and the sand grains that will be used for making emery wheel is put in grinding wheel die, under the high pressure effect, sand grains is pressed into emery wheel.Existing grinding wheel die is made up of modular ring, upper die and lower die and the core rod that in the upper die and lower die centre bore, is provided with, and core rod is an integral structure, and the technical problem that the core rod of this structure exists is to be difficult for die sinking, and die wear is more serious, and die life is shorter.
The utility model content
The purpose of the utility model is to solve the technical problem that is difficult for die sinking, die wear that existing grinding wheel die exists.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
The grinding wheel die of the novel combination shape core rod of the utility model is made up of modular ring, upper die and lower die and the core rod that in the upper die and lower die centre bore, is provided with, and described core rod is a split-type structural, is made up of core pieces I, core pieces II and core pieces III.
The corresponding central angle of described core pieces I is the 12-17 degree, and core pieces II and core pieces III are symmetrical set.
The utility model is through the hollow core rod of installation and combination shape in counterdie and patrix centre bore; When therefore under high pressure making emery wheel, in knockout course, be convenient to the demoulding, the core pieces I is at first thrown off; Other two core pieces II and core pieces III are thrown off then, help the demoulding more.Reduced the wearing and tearing of sand grains to core rod and modular ring simultaneously, the service life of modular ring, core rod is longer.And the cost of mfg. moulding die is low; Can also improve the service life of whole grinding wheel die, thereby reduce the cost of producing emery wheel.

Fig. 1 is the vertical view of the utility model.
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
The grinding wheel die of the novel combination shape core rod of the utility model is made up of modular ring 1, patrix 2, counterdie 6 and the core rod that in patrix 2 and counterdie 6 centre bores, is provided with, and described core rod is a split-type structural, is made up of core pieces I 3, core pieces II 4 and core pieces III 5.The corresponding central angle of described core pieces I is the 12-17 degree, and core pieces II and core pieces III are symmetrical set.
Claims (2)
