Abstract
Split type die cavity axial seal mechanism of compression moulding bottle lid machine mould, including the die cavity body and the trade mark base of bottle lid machine mould, set up the caulking groove on the axial lateral wall of die cavity body, installation sealing washer in the caulking groove, the axial lateral wall and the sealing washer and the interference fit of trade mark base of die cavity body. This scheme adopts axial side to seal, does not receive about the compound die power influence, does not have and leaks, and the sealing member is motionless, and interference fit makes sealing washer and trade mark base contact surface hug closely seamless, does not have the problem that produces the height unevenness, and the suppression product does not have overlap, die cavity long service life.
Description
Technical Field
The utility model relates to a split type die cavity axial seal mechanism of compression moulding bottle lid machine mould belongs to plastics machinery.
Background
Compression moulding bottle lid machine is one of the equipment commonly used for producing the plastics bottle lid, and when production, need set up the trade mark in the bottom surface of bottle lid, consequently, when processing bottle lid die cavity, for processing convenience, generally adopt split type die cavity, be about to the die cavity and divide into die cavity body and trade mark base, but the sealed mode of the split type die cavity of conventionality is that the junction plane is sealed, sets up the sealing washer on the interior bottom surface of trade mark base promptly, and its shortcoming is: firstly, gaps are easily generated on the upper and lower sealing surfaces, and plastic enters a pressed bottle cap to generate flash; and secondly, the sealing ring is influenced by the extrusion of the die closing pressure for a long time, and the contact surface is easy to generate unevenness to press unqualified products.
Disclosure of Invention
The utility model aims at overcoming prior art's shortcoming, providing an adopt axial side seal structure, the sealing member is static motionless, does not receive the influence of upper and lower compound die power, does not have and leaks, and the product does not have overlap, the split type die cavity axial seal mechanism of compression moulding bottle lid machine mould of die cavity long service life.
The utility model discloses split type die cavity axial seal mechanism of compression moulding bottle lid machine mould is: the bottle cap machine die comprises a die cavity body and a trademark base of a bottle cap machine die and is characterized in that an embedded groove is formed in the axial side wall of the die cavity body, a sealing ring is installed in the embedded groove, and the axial side wall of the die cavity body, the sealing ring and the trademark base are in interference fit.
The utility model discloses a split type die cavity axial seal mechanism of compression moulding bottle lid machine mould, in actual production, influenced by processing technology and assembly precision, existing split type die cavity all is plane seal, the sealing washer is influenced by joint die pressure extrusion easily, this scheme adopts axial side seal, do not receive the influence of upper and lower compound die power, do not have and leak, sealing member static, interference fit makes sealing washer and trade mark base contact surface hug closely seamless, do not have the uneven problem of production height, the suppression product does not have the overlap, die cavity long service life.
Drawings
Fig. 1 is the structural schematic diagram of the split type cavity axial sealing mechanism of the present invention.
Detailed Description
The utility model relates to a split type die cavity axial seal mechanism of compression moulding bottle lid machine mould, as shown in figure 1, including the die cavity body 1 and the trade mark base 2 of bottle lid machine mould, its main technical characterized in that set up caulking groove 3 on the axial lateral wall of die cavity body 1, installation sealing washer 4 in the caulking groove, the axial lateral wall and the sealing washer 4 and the 2 interference fit of trade mark base of die cavity body 1. In actual production, influenced by processing technology and assembly precision, existing split type die cavity is plane seal, and the sealing washer is easily influenced by mould clamping pressure extrusion, and this scheme adopts axial side seal, does not receive about the clamping force influence, does not have and leaks, and the sealing member is motionless, and interference fit makes sealing washer and trade mark base contact surface hug closely seamless, does not have the problem that produces the height unevenness, and the suppression product does not have the overlap, die cavity long service life.
