Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a fixing clamp for processing glass bottle molds. Background Technology
[0002] Glass molds are essential equipment for manufacturing glass containers such as various beer bottles, wine bottles, beverage bottles, and even daily cosmetic bottles. The mouth mold is a crucial component in the glass mold assembly that controls the shaping of the glass container's mouth. It is made of mold steel. First, the steel round bar is cut according to the size requirements of the mouth mold, then it is cleaved in the middle, and then a series of processes such as machining the positioning reference surface, the mold parting surface, and the mold cavity are carried out until the finished mouth mold product that can be put into use is obtained.
[0003] Existing die-cutting processes require a fixture to hold the die in place, typically using a hydraulic cylinder for pressing. However, due to the gap between the cylinder's pressing extension end and the die, and the relatively long extension distance of the cylinder's extension end, it is prone to swaying and deflection during the extension and retraction process, preventing it from moving linearly along its axis. Furthermore, since the outer edge of the die is not planar, it cannot be precisely pressed against the center surface of the die, resulting in a misaligned pressing phenomenon. Consequently, the die may not be securely fixed, and the fixed die may easily loosen. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing fixture for processing glass bottle mold openings, which solves the problems of the existing top-pressure oil cylinder having a long extension distance at the telescopic end, which is prone to deflection and shaking during movement, reducing clamping accuracy, and making the mold opening not firmly clamped and easy to loosen.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] This utility model provides a fixing fixture for processing glass bottle mold openings. The glass bottle mold opening includes a left mold and a right mold. The fixing fixture includes a base, on which are provided:
[0007] A center positioning block, which is detachably mounted on the base;
[0008] The top-pressing cylinder has two cylinders, which are respectively located at both ends of the base along its length and symmetrically arranged along the central positioning block. The telescopic end of the top-pressing cylinder is located between the central positioning block and the left die placement position / right die placement position.
[0009] The number of the clamping pins corresponds to the number of the top-pressure cylinders. One end of each clamping pin is provided with an external thread, and the end of the telescopic end of each top-pressure cylinder is provided with a connecting groove. The inner wall of the connecting groove is provided with an internal thread that mates with the external thread.
[0010] Furthermore, the center positioning block and the corresponding top pressure cylinder can be detachably provided with limiting plates on their opposite sides. One of the limiting plates has a limiting groove I that mates with the protrusion on the left die on its side, and the other limiting plate has a limiting protrusion that mates with the groove on the right die on its side.
[0011] Furthermore, both of the opposite sides of the two limiting plates are vertically provided with clearance grooves.
[0012] Furthermore, each of the two opposing sides of the limiting plates is provided with a horizontally shaped hole, and a fixing screw for fixing the limiting plate to the central positioning block is provided in the shaped hole.
[0013] Furthermore, positioning protrusions are vertically provided on the adjacent sides of the two limiting plates, and a positioning groove is provided on the central positioning block to cooperate with the positioning protrusions.
[0014] Furthermore, the bottom end of the central positioning block is provided with a limiting protrusion, and the base is provided with a limiting groove II that cooperates with the limiting protrusion. The two ends of the limiting groove II extend opposite to each other along the width direction of the base.
[0015] Furthermore, inverted T-shaped grooves are provided on the base at the four corners of the main body of the top pressure cylinder. Inverted T-shaped bolts are installed in the inverted T-shaped grooves, and the top of the inverted T-shaped bolts slides through the main body of the top pressure cylinder and is threadedly connected to a fixing nut.
[0016] Furthermore, each of the bases located within the left die placement position / right die placement position is provided with a die support seat, and one side of the die support seat is in close contact with the limiting plate.
[0017] Furthermore, at least two planes are provided on the outer edge of the other end of the abutment post along its circumference, and the at least two planes are symmetrically arranged along the radial line of the abutment post.
[0018] Furthermore, a positioning key is provided on the base at the bottom end of the main body of the top-pressing cylinder, and a positioning keyway that cooperates with the positioning key is provided on the main body of the top-pressing cylinder.
[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0020] This utility model discloses a fixing fixture for processing glass bottle mold openings, comprising a base, a central positioning block, a top-pressing cylinder, and a clamping column. The central positioning block is detachably mounted on the base. There are two top-pressing cylinders, respectively located at both ends of the base along its length and symmetrically arranged along the central positioning block. The extension / retraction ends of the top-pressing cylinders are positioned between the central positioning block and the left / right mold opening position. The number of clamping columns corresponds to the number of top-pressing cylinders. One end of each clamping column has an external thread, and the extension / retraction end of each top-pressing cylinder has a connecting groove. The inner wall of the connecting groove has an internal thread that mates with the external thread. By threading a clamping column to the telescopic end of the top-pressing cylinder, the distance between the clamping column and the center positioning block can be reduced by screwing the clamping column, thereby reducing the distance the telescopic end of the top-pressing cylinder moves. Under the premise that the die clamping can be achieved by moving a shorter distance, the movement of the clamping column driven by the top-pressing cylinder is more stable and less prone to shaking or deflection, thereby improving the firmness and accuracy of the clamping column pressing the left or right die.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0034] refer to Figure 1 This utility model provides a fixing fixture for processing glass bottle mold openings. The glass bottle mold opening 1 includes a left opening 11 and a right opening 12. The left opening 11 is provided with at least one protrusion 13, and the right opening 12 is provided with at least one groove 14 that cooperates with the protrusion 13 on the left opening 11.
[0035] Specifically, refer to Figure 2 and Figure 3The fixing fixture includes a base 2, on which a central positioning block 3, two top-pressing cylinders 4 and abutting columns 5 corresponding to the number of top-pressing cylinders 4 are provided. The central positioning block 3 is detachably installed on the base 2. The two top-pressing cylinders 4 are respectively located at both ends of the base 2 along the length direction and are symmetrically arranged along the central positioning block 3. The telescopic end of the top-pressing cylinder 4 and the central positioning block 3 are the left die placement position 6 and the right die placement position 7.
[0036] refer to Figure 2 and Figure 3 Each clamping post 5 has an external thread 8 at one end, and the corresponding extension end of the top pressure cylinder 4 has a connecting groove 9. The inner wall of the connecting groove 9 has an internal thread 10 that mates with the external thread 8.
[0037] refer to Figure 1 , Figure 2 and Figure 3 During operation, the left die 11 or the right die 12 is fixed by the top-pressing cylinder 4 and the center positioning block 3. Since the clamping pin 5 is threadedly connected to the telescopic end of the corresponding top-pressing cylinder 4, it can be screwed down to reciprocate along the circumference of the telescopic end of the top-pressing cylinder 4, thereby adjusting the distance between the clamping pin 5 and the left die 11 placed in the left die placement position 6, or the distance between the clamping pin 5 and the right die 12 placed in the right die placement position 7. Under the premise of ensuring that the top pressure cylinder 4 drives the clamping column 5 to move, the clamping column 5 is screwed to move along the axial direction of the telescopic end of the top pressure cylinder 4 towards the left die 11 or the right die 12, reducing the distance between the clamping column 5 and the left die 11 or the right die 12. This can shorten the distance of subsequent movement of the clamping column 5 driven by the top pressure cylinder 4, and ensure the stability of the movement of the clamping column 5 driven by the top pressure cylinder 4, thereby improving the firmness and accuracy of the clamping column 5 pressing the left die 11 or the right die 12.
[0038] refer to Figure 2 and Figure 3 At least two planes 20 are provided along the circumference on the outer edge of the other end of the clamping post 5. The at least two planes 20 are symmetrically arranged along the radial line of the clamping post 5. The planes 20 increase the contact area between the clamping post 5 and the tightening tool (wrench), making it easier for on-site workers to tighten.
[0039] refer to Figure 2 , Figure 4 and Figure 5Each of the central positioning block 3 and the corresponding top-pressing cylinder 4 has a detachable limiting plate 21 on its opposite side. One limiting plate 21 has a limiting groove I 22 on its side that fits against the left mold 11, which mates with the protrusion 13 on the left mold 11. The other limiting plate 21 has a limiting protrusion 23 on its side that fits against the right mold 12, which mates with the groove 14 on the right mold 12. By setting the limiting groove I 22 or the limiting protrusion 23 on the limiting plate 21, the purpose is to ensure that the left mold 11 or the right mold 12 can fit better with the corresponding limiting plate 21, and secondly, to provide positioning. Both limiting plates 21 have vertical clearance grooves 24 on their opposite sides. Some glass bottle mold openings 1 have multiple protrusions 13; by setting the clearance grooves 24, it can be adapted to glass bottle mold openings 1 with different numbers of protrusions 13.
[0040] refer to Figure 2 , Figure 4 and Figure 5 Each of the two opposing sides of the limiting plates 21 has a horizontally arranged oblong hole 25. A fixing screw (not shown in the figure) is installed within the oblong hole 25 to fix the limiting plate 21 to the central positioning block 3. The fixing screw and the oblong hole 25 allow for fine adjustment of the position of the limiting plate 21 on the central positioning block 3, ensuring better engagement between the protrusion 13 on the left mold 11 and the corresponding limiting groove Ⅰ22 on the limiting plate 21, or better engagement between the groove 14 on the right mold 12 and the corresponding limiting protrusion 23 on the limiting plate 21. Furthermore, different structures of the limiting plates 21 can be replaced according to the actual structure of the glass bottle mold 1, allowing for quick and easy disassembly. Each of the adjacent sides of the two limiting plates 21 has a vertically arranged positioning protrusion 26, and the central positioning block 3 has a positioning groove 27 that mates with the positioning protrusion 26. The engagement of the positioning protrusion 26 and the positioning groove 27 allows the limiting plate 21 to be quickly and accurately installed on the central positioning block 3.
[0041] refer to Figure 2 and Figure 6 The bottom end of the central positioning block 3 is provided with a limiting protrusion 28, and the base 2 is provided with a limiting groove II 29 that cooperates with the limiting protrusion 28. The two ends of the limiting groove II 29 extend opposite to each other along the width direction of the base 2. A positioning key 30 is provided on the base 2 at the bottom end of the main body of the top pressure cylinder 4, and a positioning keyway (not shown in the figure) is provided on the main body of the top pressure cylinder 4 that cooperates with the positioning key 30. During operation, the cooperation between the limiting protrusion 28 and the limiting groove II 29, as well as the cooperation between the positioning key 30 and the positioning keyway, can improve the firmness of the central positioning block 3 and the top pressure cylinder 4 on the base 2, and prevent movement when clamping and positioning the glass bottle mold opening 1.
[0042] refer to Figure 2 and Figure 6 The base 2 has inverted T-slots 31 at each of the four corners of the main body of the top-pressure cylinder 4. Inverted T-bolts 32 are installed within the inverted T-slots 31, with the tops of the bolts 32 sliding through the main body of the top-pressure cylinder 4 and threadedly connected to a fixing nut 33. By installing the inverted T-bolts 32 within the inverted T-slots 31 and using the fixing nuts 33, the top-pressure cylinder 4 can be fixed. Furthermore, the position of the top-pressure cylinder 4 on the base 2 can be finely adjusted, allowing the clamping pins 5 on the top-pressure cylinder 4 to better abut against the left die 11 or the right die 12, thus improving the clamping stability.
[0043] refer to Figure 2 Both the left die placement position 6 and the right die placement position 7 are equipped with die support seats 34. One side of the die support seat 34 is closely attached to the limiting plate 21. The die support seat 34 supports the left die 11 or the right die 12 and limits its height, which enables better subsequent processing of the fixed left die 11 and right die 12. Die support seats 34 of different thicknesses can be replaced according to the actual processing situation.
[0044] In summary, the fixing fixture for processing glass bottle mold openings using this structure is simple and easy to operate. Under the premise of ensuring that the top-pressing cylinder 4 drives the clamping column 5 to move, the clamping column 5 can be rotated to move along the axial direction of the telescopic end of the top-pressing cylinder 4 towards the left mold 11 or the right mold 12, reducing the distance between the clamping column 5 and the left mold 11 or the right mold 12. This can shorten the distance of subsequent movement of the clamping column 5 driven by the top-pressing cylinder 4, ensuring the stability of the movement of the clamping column 5 driven by the top-pressing cylinder 4, and thus improving the firmness and accuracy of the clamping column 5 pressing the left mold 11 or the right mold 12.
