Description

Technical Field

[0001] The invention relates to the technical field of glass bead preparation, in particular to an improved needle threading structure for a glass bead pressing machine with holes and the glass bead pressing machine. Background Art

[0002] At present, the raw materials used to prepare glass beads are mostly natural ores. During the preparation, various ores must first be crushed and added into powders. Then, according to the glass composition, a batch material is made and sent to a glass melting furnace for melting to form molten glass. The molten glass is then drained into a press for molding to obtain glass beads. Some glass bead presses directly prepare glass beads without holes. In this regard, the pressing machine disclosed in the invention patent "A Rotary Glass Bead Automatic Press" with application number 202410578611 previously applied by the applicant can directly prepare glass beads with holes by pressing. It mainly uses a punching pin to pass through the center of the glass solution to open a hole when the pressing machine presses the glass solution. And because the working temperature of glass bead pressing is extremely high, the punching ejector needs to be made of high-cost, high-temperature resistant and expensive materials. However, in actual operation, after the punching working part of the punching ejector is worn, the entire punching ejector needs to be replaced, which not only results in low working efficiency, but also high use cost of the punching ejector, further resulting in high cost of glass beads with holes. Summary of the invention

[0003] In order to solve the above technical problems, the present invention improves the punching pin for a glass bead pressing machine with holes, and provides an improved needle threading structure for a glass bead pressing machine with holes that can be used multiple times and can reduce the overall replacement frequency.

[0004] The technical solution provided by the present invention is:

[0005] An improved needle threading structure for a glass bead pressing machine with holes comprises a left pressing die body and a right pressing die body which are arranged opposite to each other, wherein a first guide head and a second guide head are respectively arranged at the opposite ends of the left pressing die body and the right pressing die body, and further comprises a straight punching ejector pin, wherein a part of the punching ejector pin passes through the outside of the right pressing die body, and the needle body of the punching ejector pin located outside the right pressing die body is movably sleeved on a clamping part.

[0006] One implementation method is that the left pressing mold body and the right pressing mold body are respectively provided with a first mold cavity and a second mold cavity at opposite ends, and the cavity formed by the first mold cavity and the second mold cavity corresponds to the shape of the glass bead.

[0007] One implementation manner is that the cavity formed by the combination of the first mold cavity and the second mold cavity is spherical.

[0008] One implementation manner is that the second mold cavity is connected to a first hole cavity, the punching ejector pin can movably pass through the first hole cavity, and the first hole cavity passes through the second guide head.

[0009] One implementation method is that the first mold cavity is connected to a second cavity, the other end of the second cavity is connected to a slag discharge cavity, the second cavity corresponds to the first cavity, and the end of the needle top hole can pass through the second cavity to the slag discharge cavity.

[0010] One implementation method is that the slag discharge cavity is connected to a slag discharge hole that passes through the left pressing mold body.

[0011] In one implementation, the clamping portion comprises a clamping block, and the clamping block is provided with a fourth cavity 41 for the punching ejector to pass through.

[0012] One implementation method is that a penetrating positioning hole is provided at the lower portion of the fourth cavity, and a fixing screw hole is provided on the clamping block, and the fixing screw hole penetrates the side surface of the clamping block where the fourth cavity port is located.

[0013] Based on the same technical idea, the present invention also provides a glass bead pressing machine with holes, which is provided with the above-mentioned improved needle threading structure.

[0014] One implementation method is that it includes a frame, a body is provided on the upper part of the frame, the left pressing mold body and the right pressing mold body are respectively installed on the body through the left model column fixing structure and the right model column fixing structure, the left model column fixing structure and the right model column fixing structure have the same structure, the left model column fixing structure includes a fixed flange and a guide positioning gear plate, the left pressing mold body and the right pressing mold body are respectively clamped in the tooth grooves of the guide positioning gear plate, and the ends of the left pressing mold body and the right pressing mold body facing away from the first guide head and the second guide head respectively pass through the disc body of the fixed flange plate.

[0015] The advantages of the present invention compared with the prior art are:

[0016] The present invention improves the structure of the existing punching ejector pin, so that when the working part of the punching ejector pin is worn, it is only necessary to cut off the worn part, and then push the other needle body of the punching ejector pin toward the first hole cavity by using the clamping part, that is, there is no need to replace the punching ejector pin with worn working part as a whole, and it can be used multiple times, which can not only reduce the use cost of the punching ejector pin, reduce the production cost of the glass beads with holes, but also improve the work efficiency and further reduce the maintenance cost.
