Description

Technical Field

[0001] This utility model relates to the field of glass bottle forming mold technology, and in particular to a glass bottle mold end cap and a glass bottle forming mold. Background Technology

[0002] In the glass bottle forming process, a primary mold and an end cap are required. During production, the end cap is mounted on a support. When the primary mold closes below and the glass falls into it, the support clamps the end cap and lowers it onto the upper part of the primary mold, using the end cap to seal the cavity of the primary mold, thus forming the glass preform. During the glass preform forming process, the end cap needs to form a tight fit with the primary mold. However, due to the movement of the end cap and support relative to the primary mold, there is a positioning error between the support and the primary mold. To prevent over-positioning when the end cap closes the cavity of the primary mold, sufficient clearance must be left between the end cap and the support. However, due to the large clearance between the end cap and the support, when the support moves and lowers the end cap, there is noticeable wobbling. During the process of the end cap falling and closing the primary mold, if the closing angle of the end cap is not correct, it may bump into the primary mold and cause damage, affecting the forming quality of the glass preform.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0024] Reference Figures 1 to 3 As shown, this utility model provides a glass bottle mold end cap.

[0025] Reference Figure 1 As shown, the glass bottle mold end cap includes a mounting bracket 100, an end cap 200, and multiple elastic units 300.

[0026] The bottom of the mounting bracket 100 is provided with a mounting groove 110, and the top of the plug 200 is provided with a mounting seat 210. The mounting seat 210 cooperates with the mounting groove 110 to connect the plug 200 to the mounting bracket 100. Sufficient space is left between the top wall of the plug 200 and the bottom wall of the mounting bracket 100, while gaps are left between the inner side wall of the mounting groove 110 and the outer side wall of the mounting seat 210. For example, there is a gap between the top wall of the mounting seat 210 and the top wall of the mounting groove 110, and a gap between the vertical surface of the mounting seat 210 and the vertical surface of the mounting groove 110. The gaps can be set according to the size of the plug 200. The gaps are generally less than 5mm, or they can be set to less than 1mm, so that the plug 200 can move a small distance relative to the mounting bracket 100. The plug 200 can move relative to the mounting bracket 100 in the vertical and horizontal directions.

[0027] In this embodiment, the mounting base 210 is cylindrical in shape. An outwardly protruding annular protrusion 220 is provided on the outer wall of the mounting base 210, encircling the circumference of the mounting base 210. The mounting groove 110 is cylindrical in shape, and an outwardly recessed annular groove 130 is provided on the inner wall of the mounting groove 110, encircling the circumference of the mounting groove 110. The annular protrusion 220 and the annular groove 130 cooperate to fix the mounting base 210 in the mounting groove 110 and prevent the end cap 200 from falling off the mounting bracket 100. Furthermore, there are gaps between the inner wall of the mounting groove 110 and the outer wall of the mounting base 210, gaps between the top wall of the annular protrusion 220 and the top wall of the annular groove 130, and gaps between the vertical surface of the annular protrusion 220 and the vertical surface of the annular groove 130.

[0028] There are multiple ways to connect the mounting base 210 and the mounting slot 110.

[0029] For example, the diameter of the mounting groove 110 gradually decreases from top to bottom, the shape of the mounting base 210 matches the shape of the mounting groove 110, and there is a gap between the inner side wall of the mounting groove 110 and the outer side wall of the mounting base 210, which can also achieve the connection between the mounting base 210 and the mounting groove 110 and the end cap 200 can move a small distance relative to the mounting bracket 100.

[0030] Alternatively, a protrusion is provided on the inner side wall of the mounting groove 110, and a groove is provided on the outer side wall of the mounting base 210. The protrusion and the groove cooperate, and a gap is left between the inner side wall of the mounting groove 110 and the outer side wall of the mounting base 210. This can also achieve the connection between the mounting base 210 and the mounting groove 110, and the end cap 200 can move a small distance relative to the mounting bracket 100.

[0031] Alternatively, the mounting base 210 can be inserted into the mounting groove 110 from bottom to top. A through connecting hole is provided at the top of the mounting groove 110. A fastener is used to pass through the connecting hole and connect to the top of the mounting base 210. The fastener abuts against the top of the mounting bracket 100. There is a gap between the fastener and the connecting hole, and there is also a gap between the inner side wall of the mounting groove 110 and the outer side wall of the mounting base 210. This also allows the mounting base 210 to be connected to the mounting groove 110 and the end cap 200 to move a small distance relative to the mounting bracket 100.

[0032] Reference Figure 2 As shown, the inner wall of the mounting groove 110 is provided with a plurality of horizontally penetrating mounting holes 120. These mounting holes 120 are arranged in a circular array around the axis of the mounting groove 110, with the axis of each mounting hole 120 passing through the center of the mounting groove 110. In this embodiment, referring to... Figure 2As shown, there are three mounting holes 120. The axes of the three mounting holes 120 intersect at the center of the mounting groove 110, and the included angle between the axes of any two adjacent mounting holes 120 is 120°.

[0033] Reference Figure 1 and Figure 2 As shown, multiple elastic elements 300 are respectively disposed in multiple mounting holes 120. In this embodiment, three elastic elements 300 are respectively disposed in three mounting holes 120.

[0034] Reference Figure 3 As shown, each elastic unit 300 is provided with a housing 330, an elastic element 310 and an abutment element 320. The housing 330 has an accommodating cavity 331 extending along the axis inside. One end of the housing 330 is provided with a screw groove and the other end is provided with an opening 332, which connects to the accommodating cavity 331. The elastic element 310 is a spring, which is located at one end of the receiving cavity 331 near the screw groove. The abutment 320 is located at one end of the receiving cavity 331 near the opening 332. The two ends of the elastic element 310 abut against the inner wall of the receiving cavity 331 and the abutment 320 respectively. The elastic force of the elastic element 310 pushes the abutment 320 to move towards the opening 332. The abutment 320 is spherical. The diameter of the opening 332 is smaller than the diameter of the abutment 320. The abutment 320 is pushed by the elastic element 310 so that at least a part of the spherical surface of the abutment 320 passes through the opening 332 and extends into the mounting groove 110, so that the spherical surface of the abutment 320 abuts against the outer wall of the mounting base 210.

[0035] The housing 330 protects the elastic element 310 and the abutment element 320, preventing the elastic element 310 or the abutment element 320 from wearing down the inner wall of the assembly hole 120.

[0036] The diameter of the opening 332 is smaller than the diameter of the abutment 320 to prevent the abutment 320 from detaching from the housing 330 through the opening 332.

[0037] Therefore, refer to Figure 2 As shown, the spherical surfaces of the abutment members 320 of the three elastic units 300 abut against the outer side wall of the mounting base 210 respectively, and the angle between any two adjacent lines connecting the contact point of each abutment member 320 with the center of the mounting base 210 is 120°.

[0038] Reference Figure 3As shown, the outer side wall of the housing 330 is provided with external threads (not shown in the figure), and the inner side wall of the assembly hole 120 is provided with internal threads (not shown in the figure). By turning the screw groove of the housing 330, the position of the elastic unit 300 in the assembly hole 120 is adjusted, so that the distance of the abutment 320 extending into the mounting groove 110 through the assembly hole 120 changes. In this way, the stable position of the mounting seat 210 in the mounting groove 110 can be changed, that is, the position of the end cap 200 can be finely adjusted to adapt to the position of the initial mold.

[0039] The mounting slot 110 of the mounting bracket 100 is used to connect the mounting base 210 of the plug 200. There is a gap between the mounting base 210 and the mounting slot 110 so that the plug 200 can be slightly adjusted in position relative to the mounting bracket 100, so as to avoid over-positioning when the plug 200 closes the initial mold.

[0040] Multiple assembly holes 120 are evenly spaced along the circumference of the mounting base 210. Each assembly hole 120 is provided with an elastic unit 300. The elastic unit 300 extends into the mounting groove 110 and elastically abuts against the mounting base 210 of the end cap 200. When the mounting frame 100 moves and falls the end cap 200, the multiple elastic units 300 elastically abut against the mounting base 210 of the end cap 200, greatly reducing the shaking of the end cap 200. Furthermore, during the process of the mounting frame 100 moving the end cap 200 and closing the initial mold, due to the elasticity of the multiple elastic units 300, the multiple elastic units 300 deform at the moment the end cap 200 contacts the initial mold, allowing the end cap 200 to change angle according to the shape of the initial mold, reducing the collision between the end cap 200 and the initial mold. Moreover, the end cap 200 can tightly seal the initial mold cavity, ensuring that the forming quality of the glass preform is not affected.

[0041] In some embodiments, the elastic element 300 has various structures.

[0042] For example, the elastic unit 300 includes an elastic element 310, which is disposed in the assembly hole 120. The elastic element 310 extends through the assembly hole 120 into the mounting groove 110. The elastic element 310 abuts against the mounting seat 210, and the mounting seat 210 is pushed by the elastic force of the elastic element 310.

[0043] Alternatively, the elastic unit 300 may include a tension spring, one end of which is connected to the inner wall of the mounting hole 120 and the other end of which is connected to the mounting base 210. In this case, multiple tension springs are evenly spaced along the circumference of the mounting base 210, and the multiple tension springs simultaneously pull the mounting base 210.

[0044] In the two embodiments of the above-mentioned elastic unit 300, the elastic element 310 abuts against the mounting base 210 or the tension spring is connected to the mounting base 210. The structure of the elastic unit 300 is relatively simple and easy to manufacture and maintain.

[0045] Alternatively, the elastic unit 300 includes an elastic element 310 and an abutment element 320. The elastic element 310 is installed in the assembly hole 120, and the abutment element 320 is disposed in the assembly hole 120. The abutment element 320 is connected to the elastic element 310, and the elastic element 310 pushes the abutment element 320 into the mounting groove 110 to abut against the mounting base 210.

[0046] Using the abutment 320 to abut the mounting base 210 helps to ensure that the contact points of multiple abutment 320 and mounting base 210 are on the same horizontal plane, ensuring that the mounting base 210 is subjected to uniform force and keeping the center position of the end cap 200 constant, thus avoiding angular deviation of the end cap 200.

[0047] This utility model also provides a glass bottle forming mold, including the glass bottle mold end cap as described in the above embodiments.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
