Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly described below with reference to the accompanying drawings and the description of the embodiments or the prior art, and it is obvious that the following description of the structure of the accompanying drawings is only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without any inventive work.

The technical solution provided by the present invention will be described in detail by way of embodiments with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto.

In some instances, some embodiments are not described or not in detail, as they are conventional or customary in the art.

Furthermore, the technical features described herein, or the steps of all methods or processes disclosed, may be combined in any suitable manner in one or more embodiments, in addition to the mutually exclusive features and/or steps. It will be readily appreciated by those of skill in the art that the order of the steps or operations of the methods associated with the embodiments provided herein may be varied. Any order in the drawings and examples is for illustrative purposes only and does not imply that a certain order is required unless explicitly stated to be required.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The terms "connected" and "coupled" when used in this application, encompass both direct and indirect connections (and couplings) where appropriate and where not necessary contradictory.

As shown in fig. 1, the bottle-shaped glass product mold of the present embodiment includes a neck mold 1 and a blank mold 2 arranged in this order from top to bottom, and the terms "upper" and "lower" mean that the neck mold 1 is located above the blank mold 2 when the bottle-shaped glass product mold of the present embodiment is in use.

As shown in fig. 2, the mouth mold 1 is formed by splicing two half molds, the opening and closing of the mouth mold 1 are performed by opening and closing arms of mouth mold claspers, and the two half molds are connected in a positioning manner, which is consistent with the prior art and is not described herein again. When the neck ring mold 1 is closed by the neck ring mold holding clamp arm, the relative position of the neck ring mold 1 and the primary mold 2 which need to be closed must be accurate so as to avoid the dislocation of the bottle mouth and the bottle body of the bottle-shaped glass product; on the other hand, when the punch presses the bottle-shaped glass product, an outward extrusion force is applied to the neck mold 1; therefore, the utility model discloses a this technical problem is solved to following technical scheme: as shown in fig. 3, a positioning structure 3 is arranged between the neck mold 1 and the primary mold 2; the positioning structure 3 comprises an annular rib 31 and an annular groove 32 matched with the annular rib 31; the section of the annular convex rib 31 is isosceles trapezoid; the annular convex rib 31 is arranged on the lower end face of the neck ring die 1, and the upper end face of the primary die 2 is provided with an annular groove 32; it is obvious that the annular rib 31 can also be provided on the upper face of the blank 2, whereas the lower face of the die 1 is provided with an annular groove 32. The cross section of the annular convex rib 31 is set to be isosceles trapezoid, so that the neck mold 1 can be guided when the neck mold 1 is downwards matched with the primary mold 2.

The included angle between the lower bottom and the waist of the isosceles trapezoid is 0-90 degrees, the included angle is not 0 degrees, the lower bottom is consistent with the lower bottom of the isosceles trapezoid in the mathematical field in definition, namely, the bottom with longer side length is the lower bottom. The larger the angle is, the narrower the guiding range (the distance in the radial direction of the die), and if the guiding range is to be increased, the size of the annular convex rib 31 in the vertical direction needs to be increased, and meanwhile, the up-down stroke of the die 1 needs to be increased; the smaller the angle, the wider the guiding range, but the lower the surface roughness value of the outer surface of the annular projected ridge 31 is required, otherwise the guiding function cannot be performed, which in turn increases the processing cost. Thus, the angle between the lower base and the waist is preferably between 45 ° and 75 °. As shown in fig. 4, in the present embodiment, in the isosceles trapezoid, the angle between the lower base and the waist is 60 °.

During the use, the primary mould 2 is installed on the carousel, and the carousel is fixed with the mount pad, and the mounting hole has been seted up to the mount pad top surface, and the pore wall of mounting hole has seted up threaded hole, and threaded hole female connection has the bolt, through radial position and the vertical position of bolt restriction primary mould 2, as shown in fig. 1 to 3, in this embodiment, primary mould 2 lower extreme is big end down's taper, can avoid primary mould 2 in the use, upwards the drunkenness.

As shown in fig. 4, a through hole is formed in the middle of the neck ring mold 1; the through hole comprises a guide ring hole 11, a punch matching hole 12 and an interface hole 13 which are sequentially connected from top to bottom; the guide ring 4 is matched in the guide ring hole 11, a flange 41 extends outwards from the upper end of the guide ring 4, and a flange groove 14 matched with the flange 41 is formed in the hole wall of the guide ring hole 11. The punch fitting hole 12 is used for fitting with a punch (not shown in the figure) to guide the punch; the mouthpiece 13 is used for forming the mouth of a bottle-shaped glass product. When the neck ring mold embracing tong arm opens and closes the neck ring mold 1, the guide ring 4 plays a role in guiding, and the dislocation of the neck ring mold 1 is avoided.

As shown in fig. 4, the upper portion of the punch engaging hole 12 is tapered in a large upper portion and a small lower portion, thereby facilitating the guidance of the punch.

As shown in fig. 4, in the present embodiment, the tip of the die 1 is tapered so as to be small in the upper part and large in the lower part.

As shown in fig. 2 and 3, in the present embodiment, an annular rib 15 is provided so as to protrude outward from the outer circumferential surface of the die 1, and the die 1 is positioned when the die 1 is attached to the arm of the die holder.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
