Description

Technical Field

[0002] A glass mold is an important equipment for manufacturing glass containers such as various beer bottles, red wine bottles, beverage bottles and even daily cosmetic bottles. The die is an important component in the glass mold assembly for controlling the forming of the mouth part of the glass container. It is made of die steel. First, a steel round bar is cut according to the size requirements of the die, then it is split in the middle, and then through a series of processes such as machining of the positioning reference surface, the mating surface and the mold cavity, until the finished die product that can be put into use is obtained.

[0003] After the steel round bar is cut, two semi-circular structures will be formed, and there will be grooves and protrusions on the cut surfaces of the two semi-circular structures, which is to facilitate the accurate splicing of the two semi-circular structures together. When processing the die, it is necessary to process the top surfaces (i.e., semi-circular surfaces) of the two semi-circular structures. However, the existing fixtures cannot clamp the two semi-circular structures at the same time. Generally, the two semi-circular structures are clamped in two times and processed separately, which may lead to inconsistent position accuracy during the two clamping processes, resulting in inconsistent machining accuracy of the two semi-circular structures and affecting subsequent processes such as die mating and mold cavity machining of the die.

Specific embodiments

[0026] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 - Figure 2 shown, a preferred embodiment of the present invention provides a die plate circular clamping tooling, which mainly includes components such as an upper fixing plate 1, a lower fixing plate 2, a clamping oil cylinder 13, a clamping block 4, a pressure rod 7, etc. Among them, the upper fixing plate 1 is located above the lower fixing plate 2 and is parallel to it. The two sides of the upper fixing plate 1 and the lower fixing plate 2 are connected by side plates 3 to form a support structure. Four clamping oil cylinders 13 are installed on the lower fixing plate 2. The clamping oil cylinder 13 is a double-rod type and has two output ends, and the conveying directions of the two output ends are opposite. A connecting rod is fixedly connected to each output end, and the other end of the connecting rod is hinged to the pressure rod 7.

[0028] In this embodiment, a total of four clamping blocks 4 are provided, and eight pressure rods 7 are provided. One pressure rod 7 is hinged to each of the two output ends of each clamping oil cylinder 13. The eight pressure rods 7 are grouped in pairs of two, and the two pressure rods 7 in each group correspond to the two sides of the clamping block 4 respectively. Four clamping oil cylinders 13 are provided, which are respectively located directly below the four clamping blocks 4 and are used to control the rotation of the pressure rods 7 and cooperate with the clamping blocks 4 to clamp the two semi-circular structures of the die plate respectively.

[0029] In other technical solutions, eight clamping cylinders 13 can also be provided. Each clamping cylinder 13 has only one output end, and a pressure bar 7 is hinged to the output end of each clamping cylinder 13.

[0030] Reference Figure 1 , there is a chute in the middle of the upper fixing plate 1. The chute extends along the length direction of the upper fixing plate 1. At the same time, a sliding part 401 is formed by a protrusion at the bottom of each clamping block 4. The sliding part 401 is slidably connected to the chute, so as to adjust the distance between the four clamping blocks 4. In this embodiment, the four clamping blocks 4 are distributed at intervals, and then fixed to the upper fixing plate 1 by bolts.

[0031] Four rectangular insertion holes are opened on both sides of the upper fixing plate 1. A pin seat 10 is fixed on both sides of each insertion hole by bolts. The other end of the pressure bar 7 passes through the insertion hole and is hinged to the corresponding two pin seats 10 by a pin shaft. The size of the insertion hole is larger than the cross-sectional size of the pressure bar 7, so that the insertion hole can limit the rotation angle of the pressure bar 7. When the output end of the clamping cylinder 13 extends, the pressure bars 7 on both sides of the clamping block 4 will rotate towards each other, so as to clamp the two semi-circular structures of the die.

[0032] Reference Figure 3 , a limiting groove is opened at the top end of each pressure bar 7, and a top block 8 is hinged in the limiting groove. The top block 8 can rotate relative to the pressure bar 7, so as to adjust the rotation angle of the top block 8.

[0033] As Figure 3 , Figure 5 shown, a top head screw 9 is threadedly connected to the front end of the top block 8, which is used to tightly press the arc surfaces of the two semi-circular structures of the die. The top head screw 9 will tightly press the middle part of the two semi-circular structures of the die, so that there is a certain distance between the top head screw 9 and the upper edge of the die, leaving enough machining space for machining the upper surface of the die and the upper side surface of the arc surface (i.e., the part above the top head screw 9). In order to prevent the top head screw 9 from sliding relative to the arc surface, a friction surface 91 is provided on the front end surface of the top head screw. The friction surface 91 is formed by a number of small protrusions, which is used to increase the friction between the top head screw and the arc surface, so as to facilitate the top head screw to clamp the two semi-circular structures of the die.

[0034] In other technical solutions, the friction surface 91 can also be formed in other ways, such as a friction coating, etc.

[0035] As Figure 4As shown, in order to position the two semicircular structures of the die, a first clamping plate 5 and a second clamping plate 6 are respectively provided on both sides of each clamping block 4. At the same time, positioning grooves are provided on both sides of the clamping block 4, and the positioning grooves extend up and down. Positioning parts formed by outward protrusions are provided on the opposite sides of the first clamping plate 5 and the second clamping plate 6, and the positioning parts are embedded in the positioning grooves, so that after the first clamping plate 5 and the second clamping plate 6 are fixed on both sides of the clamping block 4, there will be no left-right deviation, ensuring the accuracy of clamping.

[0036] The joint surfaces of the two semicircular structures of the die are provided with grooves and protrusions respectively, in order to accurately join the two semicircular structures together. For this purpose, a positioning protrusion 601 and a positioning groove 501 are respectively provided on the side of the first clamping plate 5 and the second clamping plate 6 away from the clamping block 4, and the shapes of the positioning protrusion 601 and the positioning groove 501 are respectively adapted to the structures of the grooves and protrusions on the two semicircular structures.

[0037] During clamping, the protrusions on the two semicircular structures will be embedded in the positioning grooves 501, and the positioning protrusions 601 on the clamping plate will be embedded in the grooves on the semicircular structure, so that the two semicircular structures can be accurately positioned. At the same time, the side planes of the semicircular structures will be completely in contact with the first clamping plate 5 and the second clamping plate 6. Then the clamping cylinder 13 controls the rotation of the pressure rods 7 on both sides, and the top screw 9 at the top of the pressure rod 7 will support the middle of the arc surface of the semicircular structure, clamping the two parts of the die in a point-to-surface coordination manner, while ensuring the uniformity of the clamping position to ensure the consistency of subsequent processing accuracy.

[0038] An oil circuit board 11 is also fixed on one side of the side plate 3 for installing four reversing valves 12. The upper and lower sides of both ends of the oil circuit board 11 are fixed on the side plate 3 and the lower fixed plate 2 through angle irons. The four reversing valves 12 are respectively connected to the four clamping oil cylinders 13 through oil circuit pipelines to control the conveying direction of the oil circuit, thereby controlling the extension and contraction direction of the output ends of the clamping oil cylinders 13 at both ends, and controlling the clamping of the die.

[0039] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
