Description

Sliding type automatic air inlet choke plug

Technical Field

The utility model relates to a glass mold choke plug, in particular to a sliding type automatic air inlet choke plug.

Background

Need carry out preliminary shaping through the primary mould in the glassware manufacture process, the glass material gets into and need blow the suppression respectively to both ends behind the primary mould, and the effect of vexed head provides inlet channel when blowing from the top down on the one hand, and on the other hand cooperates the primary mould to carry out the top shaping when blowing from the bottom up. The existing choke plug structure needs to complete the two functions and is often matched with a washer funnel to jointly act. As shown in fig. 1, during blowing, the gasket funnel 100 is mounted between the bulkhead 101 and the blank mold 102, so that the air inlet channel 103 of the bulkhead 101 communicates with the cavity of the blank mold 102. As shown in fig. 2, when the air is blown from the bottom to the top, the gasket funnel 100 is taken out, the air inlet channel 103 of the bulkhead 101 is closed by the matching surface of the top of the primary mold 102 and the bulkhead 101, and the bottom surface of the bulkhead 101 and the mold cavity of the primary mold 102 are combined to form a molding cavity, so as to complete the molding of the glass frit. Above-mentioned structure makes need twice when a glass products primary forming get and put the vexed head of high temperature, and this quickens the wearing and tearing of vexed head, has increased long-term in operation in addition, is unfavorable for improving production efficiency.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned prior art defect, the utility model discloses a task lies in providing a slidingtype automatic vexed head that admits air, solves the blank mould and need the vexed head subassembly of a lot of composite set installation easily to take place wearing and tearing and the problem that efficiency is not high in the forming process.

The utility model discloses technical scheme is such: the utility model provides an automatic vexed head of admitting air of slidingtype, includes vexed head body and activity plunger, the bottom circumference of vexed head body is with former mould top complex fitting surface, the bottom surface of vexed head body be with former mould's shaping chamber complex shaping face, the vexed head body is equipped with vertical perforating hole, the activity plunger set up in the vertical perforating hole and with vexed head body sliding fit, be equipped with the restriction on the vexed head body the limit structure of sliding distance about the activity plunger, the activity plunger is equipped with the intercommunication the top surface of activity plunger and the air flue of lateral wall, when the activity plunger is located the extreme position the air flue is located the export of lateral wall is sealed, when the activity plunger is located the extreme position the air flue is located the export of lateral wall is opened.

The utility model discloses a choke plug body assembly is behind the primary mould top, when from last down blowing, the activity plunger glides to the lower extreme position by self gravity, and the air flue makes the shaping chamber of primary mould communicate with the outside this moment, through the air flue at the entry of the top surface of activity plunger action of blowing; when blowing from making progress down, the shaping intracavity frit pushes up and makes the activity plunger move up to supreme extreme position, and the air flue is closed this moment, and the shaping chamber of the bottom surface cooperation primary mould of the bottom surface of activity plunger and vexed head body is to the top shaping of glass primary mould.

Further, the air flue includes vertical blind hole way and slant passageway, vertical blind hole way set up in the center of activity plunger, the slant passageway pierces through the lateral wall of activity plunger with vertical blind hole says the intercommunication.

Furthermore, the inclined channel is provided with a plurality of inclined channels and is positioned at the circumferential side wall equally dividing position of the movable plunger.

Further, limit structure including set up in the axial spacing groove of the lateral wall of activity plunger and be fixed in the stop screw of bulkhead body, the head of stop screw with the cooperation of axial spacing groove.

Further, the movable plunger comprises a cylindrical section and a truncated cone section, the truncated cone section is small in upper portion and large in lower portion, the cone section is connected to the lower portion of the cylindrical section, and the lower portion of the vertical through hole is a taper hole matched with the truncated cone section.

Further, the outlet of the air passage at the side wall is located at the cylindrical section.

Compared with the prior art, the utility model the advantage lie in: the choke plug blows from top to bottom and blows the in-process from bottom to top, does not need the repeated installation choke plug, also does not need extra pushing operation to the choke plug, convenient operation, and production efficiency is high, and the fitting surface of choke plug and primary mould is also difficult wearing and tearing, and life is longer.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 3 to 5, the sliding type automatic air intake choke plug according to the present embodiment includes a choke plug body 1 and a movable plunger 2, a fitting surface 11 is formed at the bottom of the choke plug body 1 along the circumferential direction and is fitted to the top of the primary mold, and a molding surface is formed at the bottom of the choke plug body 1 and is fitted to the molding cavity of the primary mold. The central part of the choke plug body 1 is provided with a vertical through hole 12, and the lower part of the vertical through hole 12 is a taper hole 12a with a small upper part and a big lower part. The movable plunger 2 is arranged in the vertical through hole 12, the movable plunger 2 comprises an upper cylindrical section 21 and a lower truncated conical section 22, and the truncated conical section 22 is connected below the cylindrical section 21 in a small-end-up manner. Activity plunger 2 is sliding fit with bulkhead body 1, and for the convenience of the slip of activity plunger 2, the cylinder section 21 and the vertical perforating hole 12 of activity plunger 2 adopt clearance fit, if activity plunger 2 and vertical perforating hole 12 adopt same cylindric from last to down, then there will be the clearance equally between the bottom surface of bulkhead body 1 and the bottom surface of activity plunger 2, this top shaping that is unfavorable for the frit, and the cooperation of adoption cone section, have the effect of automatic centering location and can eliminate the clearance to activity plunger 2.

Be equipped with limit structure of restriction activity plunger 2 sliding distance from top to bottom on bulkhead body 1, limit structure is including setting up in the axial spacing groove 23 of the lateral wall of activity plunger 2 and being fixed in bulkhead body 1's stop screw 3, and stop screw 3's head and axial spacing groove 23 cooperation. The movable plunger 2 is provided with an air passage 4 communicated with the top surface and the side wall of the movable plunger 2, the air passage comprises a vertical blind hole channel 41 and an oblique channel 42, the vertical blind hole channel 41 is arranged in the center of the movable plunger 2, and the oblique channel 42 penetrates through the side wall of the movable plunger 2 and is communicated with the vertical blind hole channel 41. When the movable plunger 2 is positioned at the upper limit position, the outlet of the air channel 4 positioned on the side wall is closed, and when the movable plunger 2 is positioned at the lower limit position, the outlet of the air channel 4 positioned on the side wall is opened. When blowing air from top to bottom, as shown in fig. 5, the movable plunger 2 slides down to the lower limit position due to the self gravity and air pressure of the movable plunger 2, and the air enters the interior of the primary mold through the opened air passage 4; when blowing air from bottom to top, as shown in fig. 4, the frit pushes the movable plunger 2 back into the vertical through hole 12, the air passage 4 is closed, and the top of the frit is formed by the bottom surfaces of the choke plug body 1 and the movable plunger 2.
