Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to an anti-detachment clamping mechanism for milling both sides of a mold. Background Technology

[0002] When forming glass bottles, the glass forming mold needs to come into contact with the high temperature of the glass material. Therefore, the mold material has high requirements for high temperature resistance. Cast iron or copper alloy materials are usually used for casting the mold blank.

[0003] During the machining of the mold blank, milling is required on both sides of the mold to obtain two flat surfaces, which facilitates positioning and holding during subsequent machining. In the existing technology, the mold blank is simply pressed onto the milling machine. In order to improve the efficiency of milling, the thickness of a single feed is relatively large, and the mold blank is subjected to greater force, which can easily lead to displacement or loosening. Improvement is needed. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an anti-detachment clamping mechanism for milling on both sides of a mold, which improves the positioning accuracy and clamping stability of the mold and avoids the problem of offset or loosening during the milling process on both sides.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a clamping mechanism for milling both sides of a mold to prevent detachment, comprising: a mounting plate, a first lifting drive mechanism, a second lifting drive mechanism, a first L-shaped pressure block, and a second L-shaped pressure block. The first lifting drive mechanism is vertically disposed in the middle of the mounting plate, and the second lifting drive mechanism is disposed on the mounting plate and located on both sides of the first lifting drive mechanism. A pad is disposed on the mounting plate between the first lifting drive mechanism and the second lifting drive mechanism. A positioning block corresponding to the cavity of the mold is disposed on the pad. A first pressure plate is disposed at the top of the first lifting drive mechanism with both ends pointing to the corresponding side of the second lifting drive mechanism. A first stud is disposed at both ends of the first pressure plate pointing downward to the pad. The first L-shaped pressure block is disposed at the bottom of the first stud. A second pressure plate is disposed at the top of the second lifting drive mechanism pointing to the first lifting drive mechanism. A second stud is disposed on the second pressure plate pointing downward to the pad. The second L-shaped pressure block is disposed at the bottom of the second stud.

[0006] In a preferred embodiment of the present invention, the pad is provided with support strips located on both sides of the positioning block along its length.

[0009] In a preferred embodiment of this utility model, the first lifting drive mechanism and the second lifting drive mechanism are respectively hydraulic cylinders.

[0010] In a preferred embodiment of this utility model, the distance between the first L-shaped pressing block and the second L-shaped pressing block corresponds to the length of the mold.

[0011] The beneficial effects of this utility model are as follows: The anti-detachment clamping mechanism for milling both sides of a mold, as indicated by this utility model, places the mold horizontally on the pad with the cavity facing downwards. The positioning block is positioned in the cavity of the mold to improve the positioning accuracy of the mold and limit the displacement of the mold along the width direction.

[0015] 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.

[0016] Please see Figures 1-2 The embodiments of this utility model include:

[0017] like Figure 1The anti-detachment clamping mechanism for milling on both sides of the mold shown is used for horizontal fixation of the mold 17. It includes: a mounting plate 1, a first lifting drive mechanism 6, a second lifting drive mechanism 7, a first L-shaped pressure block 15, and a second L-shaped pressure block 5. The first lifting drive mechanism 6 is vertically positioned in the middle of the mounting plate 1, and the second lifting drive mechanism 7 is mounted on the mounting plate 1 and located on both sides of the first lifting drive mechanism 6. In this embodiment, the first lifting drive mechanism 6 and the second lifting drive mechanism 7 are respectively hydraulic cylinders, and their lifting can be controlled by solenoid valves. There are two second lifting drive mechanisms 7. With the cooperation of one first lifting drive mechanism 6, two molds 17 can be clamped simultaneously, improving production efficiency.

[0018] A pad 2 is provided on the mounting plate 1, located between the first lifting drive mechanism 6 and the second lifting drive mechanism 7. The pad 2 is fixed to the mounting plate 1 with screws, resulting in a robust structure. A positioning block 3 corresponding to the cavity of the mold 17 is provided on the pad 2. The mold is placed horizontally on the pad 2 with the cavity facing downwards. Figure 2 As shown, at this time, the positioning block 3 is located in the cavity of the mold, positioning the mold 17 and restricting the displacement of the mold 17 in the width direction.

[0019] The positioning block 3 can be fixed to the pad 2 with screws for easy replacement to accommodate different mold cavities 17. Support bars 4 are provided on both sides of the positioning block 3 along its length on the pad 2. The support bars 4 can be fixed to the pad 2 with screws. The mold 17 contacts the support bars 4, maintaining a gap between the mold 17 and the pad 2 to prevent iron filings on the pad 2 from affecting the clamping of the mold 17 and ensuring clamping stability.

[0020] A first pressure plate 16 is provided on the top of the first lifting drive mechanism 6, with both ends pointing to the corresponding side of the second lifting drive mechanism 7. The first pressure plate 16 has a first stud 12 pointing downward to the pad plate 2 at both ends. A first L-shaped pressure block 15 is provided at the bottom of the first stud 12, and the upper part of one end of the mold 17 is pressed by the first L-shaped pressure block 15.

[0021] A second pressure plate 8 is provided at the top of the second lifting drive mechanism 7, pointing towards the first lifting drive mechanism 6. A second stud 11 pointing downwards towards the pad is provided on the second pressure plate 8. A second L-shaped pressure block 5 is located at the bottom of the second stud 11. Figure 2 As shown, the second stud 11 is driven to descend by the second lifting drive mechanism 7, which in turn drives the second L-shaped pressure block 5 to descend, thereby pressing the upper part of the other end of the mold 17.

[0022] In this embodiment, the distance between the first L-shaped pressing block 15 and the second L-shaped pressing block 5 corresponds to the length of the mold 17. The first L-shaped pressing block 15 and the second L-shaped pressing block 5 are used to press and fix the top of both ends of the mold 17 and restrict the displacement of the mold 17 in the length direction.

[0023] To improve adaptability to different mold lengths 17, first U-shaped grooves 13 are provided at both ends of the first pressure plate 16, and first studs 12 are inserted through the first U-shaped grooves 13 to facilitate lateral and axial displacement adjustment of the first studs 12. First nuts 14 are provided on the first studs 12, located above and below the first U-shaped grooves, to fix the first studs 12 after adjustment.

[0024] like Figure 1 As shown, a second U-shaped groove 9 is provided at the end of the second pressure plate 8, and a second stud 11 is inserted through the second U-shaped groove 9 to facilitate the lateral and axial displacement adjustment of the second stud 11. Second nuts 10 are provided on the second stud 11, located above and below the second U-shaped groove 9, for tightening after adjustment. The lateral adjustment of the first stud 12 and the second stud 11 changes the distance between the first L-shaped pressure block 15 and the second L-shaped pressure block 5 to accommodate the length of the mold 17. The axial adjustment of the first stud 12 and the second stud 11 changes the height of the first L-shaped pressure block 15 and the second L-shaped pressure block 5 to accommodate the thickness of the mold 17 after it is placed horizontally.

[0025] In summary, the anti-loosening clamping mechanism for milling both sides of a mold as described in this utility model can clamp the mold and limit its displacement in the width and length directions, thereby improving clamping stability, preventing loosening during milling on both sides, making the processing safer, and providing easy adjustment with good adaptability to different mold specifications.

[0026] 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.
