Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a clamping mechanism for milling the end face of a bottle mouth mold. Background Technology

[0002] Bottle neck molds are specifically designed to shape the neck of glass bottles. Molten glass is placed into the mold, and the neck is formed through the cavity within the mold. Molten glass reaches temperatures of thousands of degrees Celsius, requiring high-temperature resistance from the mold material. Therefore, many bottle neck mold blanks are cast from high-temperature resistant copper alloys.

[0003] The rough casting of the bottle neck mold has a rough surface and lacks an effective positioning surface, requiring milling of the end face to obtain a flat end face. During the milling process, a clamping plate is typically used to hold the bottle neck mold in place to prevent it from loosening. However, the contact between the clamping plate and the bottle neck mold is not stable and cannot effectively position the mold. When the bottle neck mold contacts the milling cutter, it may still loosen under stress, affecting the machining accuracy and safety of the end face milling process. Improvements are needed. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a clamping mechanism for milling the end face of a bottle mouth mold, which improves the fixing reliability and positioning effect of the bottle mouth mold, and enhances the stability and safety of the end face milling process.

[0005] To solve the above-mentioned technical problems, the present invention provides a clamping mechanism for milling the end face of a bottle mouth mold, comprising: a base, a pad, an insert, a swing arm, and a pressure rod. The pad is horizontally disposed on the base, and the bottle mouth mold is disposed on the pad with its front face facing down. The front face of the bottle mouth mold has a concave bottle mouth cavity. The top surface of the pad has a concave embedding groove. The insert is disposed in the embedding groove and has a positioning protrusion corresponding to the bottle mouth cavity. The back face of the bottle mouth mold has a concave annular groove. The pad has first pin seats at both ends. The swing arm is rotatably disposed on the first pin seats. The pressure rod is disposed on the upper part of the swing arm and points towards the annular groove.

[0006] In a preferred embodiment of the present invention, the front of the bottle mouth mold is provided with a positioning rib located on one side of the bottle mouth cavity, and the top surface of the pad is provided with a positioning groove corresponding to the positioning rib.

[0007] In a preferred embodiment of the present invention, the first pin seat is provided with a first pin shaft that is parallel to the axial direction of the bottle mouth mold and passes through the swing arm.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1-2 The embodiments of this utility model include:

[0020] like Figure 1 The bottle neck mold end face milling clamping mechanism shown is used for clamping the bottle neck mold 4. It includes: a base 1, a pad 2, an insert 3, a swing arm 7, and a pressure rod 5. The pad 2 is horizontally mounted on the base 1, and the bottle neck mold 4 is mounted face down on the pad 2. Figure 2 As shown, the bottle mouth mold 4 has a bottle mouth cavity 42 recessed on the front side, which can be used for positioning.

[0021] In this embodiment, the top surface of the pad 2 is recessed with an embedding groove 21, and the insert 3 is disposed in the embedding groove 21. The insert 3 can be fixed by screws, making it easy to replace and adaptable to different types of bottle mouth cavities 42. The insert 3 is provided with a positioning protrusion 31 corresponding to the bottle mouth cavity 42. Through the cooperation between the bottle mouth cavity 42 and the positioning protrusion 31, the initial positioning of the bottle mouth mold 4 is performed, and the displacement of the bottle mouth mold 4 in the left and right directions is restricted.

[0022] A positioning rib 41 is provided on the front of the bottle mouth mold 4, located on one side of the bottle mouth cavity 42. The bottle mouth mold 4 and the positioning rib 41 are made of an integrated copper alloy structure. A positioning groove 22 corresponding to the positioning rib 42 is provided in the recess of the top surface of the pad block 2. The positioning groove 22 can not only cooperate with the positioning rib 42 to position the bottle mouth mold 4, but also avoid the positioning rib 42 to ensure that the front of the bottle mouth mold 4 is in stable contact with the top surface of the pad block 2.

[0023] The pad block 2 has a first pin seat 23 at both ends. The swing arm 7 can be flipped up and down and is mounted on the first pin seat 23. In this embodiment, the first pin seat 23 is provided with a first pin shaft 8 that is parallel to the axis of the bottle mouth mold 4 and passes through the swing arm 7, so that the swing arm 7 swings with the first pin shaft 8 as the center.

[0024] like Figure 1 As shown, the bottom of the swing arm 7 is provided with a second pin seat 9 located on one or both sides of the first pin seat 23. The top surface of the base 1 or the side of the pad block 2 is provided with a telescopic drive mechanism 10 that is movably connected to the second pin seat 9. In this embodiment, the telescopic drive mechanism 10 is a hydraulic cylinder, which can be telescopically controlled by a solenoid valve.

[0025] A push plate 12 extending into the second pin seat 9 is provided at the end of the telescopic drive mechanism 10. A second pin 11 parallel to the axial direction of the bottle mouth mold 4 and passing through the second pin seat 9 is provided on the push plate 12, which facilitates assembly. In this embodiment, a guide groove 91 corresponding to the end of the second pin 11 is provided vertically in the second pin seat 9, so that when the telescopic drive mechanism 10 drives the second pin 11 to move, the movement of the second pin 11 in the guide groove 91 can drive the swing of the second pin seat 9 and the swing arm 7.

[0026] An annular groove 43 is recessed on the back of the bottle mouth mold 4. The pressure rod 5 is located on the upper part of the swing arm 7 and points towards the annular groove 43, so that the swing arm 7 can drive the pressure rod 5 to move. By utilizing the cooperation between the pressure rod 5 and the annular groove 43, the bottle mouth mold 4 is pressed and axially positioned, which makes it less likely to loosen during end milling and helps to improve processing stability and safety.

[0027] The rocker arm 7 has corresponding insertion holes for the pressure rod 5, facilitating assembly. The pressure rod 5 is a threaded rod, and nuts 6 are located on both sides of the rocker arm 7 to achieve circumferential adjustment and locking of the pressure rod 5, improving its adaptability to the radius of the annular groove 43.

[0028] In this embodiment, the insertion hole is a waist hole, and the length direction of the waist hole is parallel to the axis of the bottle mouth mold 4, which is beneficial to adjust the position of the pressure rod 5 and ensure that the pressure rod 5 enters the annular groove 43 after the swing arm 7 flips, thereby improving the adaptability to the position of the annular groove 43 on different types of bottle mouth molds.

[0029] In summary, the bottle mouth mold end face milling clamping mechanism disclosed in this utility model can quickly clamp the bottle mouth mold, improve positioning accuracy and clamping reliability, and facilitate simultaneous milling of the front and rear end faces of the bottle mouth mold.

[0030] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
