Abstract
A core tube for producing gypsum hollow lathes comprises a truncated cone 1 and a cone 2. The end face diameter of the truncated end of the truncated cone 1 is larger than or equal to the bottom diameter of the cone, and the end face of the truncated end of the truncated cone 1 is connected with the bottom face of the cone 2, or the truncated cone 1 and the cone 2 are integrated. The core tube of the utility model has the advantages that the core tube is cone-shaped, and easy to demould.
Description
The utility model relates to stone manufacture tool of production field.
At present, need to insert in the plastering with the core pipe when producing gypsum hollow lath, make it to form hollow, and used core pipe is a cylinder, and when after the gypsum sets during demoulding, cylindrical core pipe is difficult for deviating from from plastering.
The purpose of this utility model is exactly to provide a kind of core pipe, its easy demoulding at the above-mentioned deficiency of core pipe of existing production gypsum hollow lath.
A kind of core pipe of producing gypsum hollow lath, form by truncated cone 1 and cone 2, the truncated ends end face diameter of truncated cone 1 is greater than or equal to the bottom surface diameter of cone, and the truncated ends end face of truncated cone 1 is connected with the bottom surface of cone 2 or truncated cone 1 and cone are one.Not end at truncated cone 1 has a transverse holes 3.Not end at truncated cone 1 is connected with draw ring 4.
Advantage of the present utility model is: the core pipe is conical, is easy to the demoulding.
Accompanying drawing is a structural representation of the present utility model.
Embodiment: the length of truncated cone 1 is 3 meters, it does not hold 60 millimeters of diameters, 57 millimeters of truncated ends diameters, 57 millimeters of the bottom surface diameters of cone 2, the truncated ends end face of the bottom surface of cone 2 and truncated cone 1 back that coincide is welded together, also truncated cone 1 and cone 2 can be processed into one.Open the transverse holes of 20 millimeters of diameters at the end of truncated cone 1, also be fixed with a draw ring 4 at the not end of truncated cone 1.Its using method is, in existing gypsum hollow lath mould, after pouring into the gypsum rubber cement wherein, this core pipe is inserted in the mould, after treating that rubber cement solidifies,, make it loosening with rotating core pipe in the transverse holes of lever insertion core pipe end, pull at draw ring again, the core pipe is deviate from from gypsum hollow lath easily.
Claims (3)
1, a kind of core pipe of producing gypsum hollow lath, form by truncated cone (1) and cone (2), the truncated ends end face diameter of truncated cone (1) is greater than or equal to the bottom surface diameter of cone, and the truncated ends end face of truncated cone (1) is connected with the bottom surface of cone (2) or truncated cone (1) and cone are one.
2, core pipe according to claim 1 is characterized in that: the not end at truncated cone (1) has a transverse holes (3).
3, core pipe according to claim 1 and 2 is characterized in that: the not end at truncated cone (1) is connected with draw ring (4).
