Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing jigs, in particular to a hot pressing machine. Background Art

[0002] After a period of production, hot-pressing molds in pulp-molded tableware machines can become clogged, resulting in substandard products. This requires disassembly, cleaning, and reassembly. The current method involves first prying the mold up with a crowbar, placing a steel pipe at the bottom, and utilizing the rolling friction of the pipe to remove the mold. During installation, the pipe is placed on the mounting plate. A manual hydraulic stacker is used to place one end of the mold onto the pipe, pushing the mold inward using the rolling motion of the pipe. The pipe is then removed, and fine-tuned with a hammer or crowbar until the mold is properly positioned.

[0003] During disassembly, the template has a very high temperature and is very heavy. It is inconvenient to lift the template and place the steel pipe at the bottom, which can easily burn or crush the operator and pose a safety hazard. During installation, the steel pipe can only roll in the direction perpendicular to the axis of the steel pipe. It needs to be knocked with a small hammer or pried with the steel pipe on one side of the axis to move it to the required position. In addition, it is also inconvenient to take out the bottom steel pipe after the template is moved into place. Utility Model Content

Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0038] For the convenience of description, as shown in the attached Figure 1 As shown, a first direction and a second direction perpendicular to each other are defined on a horizontal plane, and two sides along the second direction are defined as front and back, respectively.

[0039] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0040] Combine Figure 1-5 As shown, an embodiment of the present invention provides a hot press, comprising: a base plate 1, a mounting plate 2, a template 3, and a lifting assembly 4; the mounting plate 2 is mounted on the upper side of the base plate 1, and the template 3 is detachably mounted on the upper side of the mounting plate 2, and the outer peripheral side of the base plate 1 protrudes from the outer peripheral sides of the mounting plate 2 and the template 3; at least two mounting grooves 21 are spaced circumferentially along the outer periphery of the mounting plate 2, and the two ends of the mounting groove 21 respectively pass through the upper and lower sides of the mounting plate 2; the lifting assembly 4 is detachably provided in each of the mounting grooves 21, and the lifting assembly 4 comprises an adjusting bolt 41, a bearing seat 42, and a universal bearing 43, the bearing seat 42 is screwed to the top end of the adjusting bolt, and the universal bearing 43 is rotatably connected to the top end of the bearing seat 42; by rotating the adjusting bolt 41, the bearing seat 42 can be driven to move upward relative to the mounting plate 2, and then contact the template 3 through the universal bearing 43 and lift the template 3.

[0041] For example, the template 3 is fixedly connected to the mounting plate 2 via mounting bolts. To remove the template 3, first install the lifting assembly 4 in each mounting slot 21, then remove the mounting bolts. The adjusting bolt 41 is then rotated to drive the bearing seat 42 upward relative to the mounting plate 2. This, in turn, contacts the template 3 through the universal bearing 43 and lifts the template 3, freeing it from the contact surface of the mounting plate 2. This allows for easy removal of the template 3. This avoids the need to lift the template 3 with a crowbar and then place a steel pipe underneath it, reducing the risk of burns to the operator.

[0042] For example, there are four mounting grooves 21 arranged in the circumferential direction of the outer periphery of the mounting plate 2. When installing the template 3, the lifting assembly 4 is installed in each mounting groove 21, and the adjusting bolt 41 is turned so that the universal bearing 43 is higher than the upper end surface of the mounting plate 2. The template 3 is lifted by a manual hydraulic stacker so that one end of the template 3 falls on the two universal bearings 43 in front of the mounting plate 2. Then the template 3 is slowly pushed inward until the four universal bearings 43 all hold up the template 3. At this time, the template 3 can be easily moved by hand. After the template 3 is moved around until it is flush with the mounting plate 2, the four adjusting bolts 41 are adjusted so that the template 3 and the mounting plate 2 fit together and the installation work is completed. Finally, the lifting assembly 4 is taken out and put aside for next use. Because the temperature of the mounting plate 2 is high, long-term storage will cause the grease inside the universal bearing 43 to solidify and increase the resistance to movement. This avoids the use of hammering to adjust the installation position of the template 3, saving time and effort, and helping to improve production efficiency.

[0043] In some embodiments, the cross section of the mounting slot 21 is rectangular, and the mounting slot 21 can limit the rotation of the bearing seat 42. This is advantageous in that when the adjusting bolt 41 is rotated, the bearing seat 42 only rises or falls within the mounting slot 21.

[0044] In some embodiments, a limiting plate 22 is provided on the periphery of the mounting plate 2 , and the limiting plate 22 is connected to the mounting plate 2 and is used to cover the outer opening of the mounting slot 21 , which is conducive to better limiting the jacking assembly 4 in the mounting slot 21 .

[0045] In some embodiments, one end of the limiting plate 22 is rotatably connected to the mounting plate 2, and the outer opening of the mounting slot 21 can be closed or opened by rotating the mounting plate 2. This facilitates the installation of the lifting assembly 4 in the mounting slot 21 by rotating the limiting plate 22 to secure the lifting assembly 4 in the mounting slot 21.

[0046] In some embodiments, such as Figure 3As shown, the hot press also includes an adjusting component 5; the top surface of the base plate 1 is protruding from the position of the mounting plate 2 and is provided with a positioning groove 11; the adjusting component 5 includes a rotating shaft 51 and a handle 52, the bottom end of the rotating shaft 51 is rotatably arranged in the positioning groove 11, and a gap is left between the outer periphery of the rotating shaft 51 and the outer peripheral side of the mounting plate 2, and the handle 52 includes a first cantilever 521 and a second cantilever 522, one end of the first cantilever 521 is connected to one end of the second cantilever 522, and the position where the first cantilever 521 and the second cantilever 522 are connected is connected to the top of the rotating shaft 51; when the other end of the second cantilever 522 is rotated, the first cantilever 521 can be rotated, thereby driving the outer peripheral surface of the other end of the first cantilever 521 to be against the peripheral surface of the template 3.

[0047] During the process of disassembling or installing the template 3 , the movement direction of the template 3 can be roughly limited by rotating the handle 52 , which is conducive to cooperating with the jacking assembly 4 to smoothly complete the disassembly or installation steps.

[0048] In some embodiments, the mounting grooves 21 are respectively provided on both sides of the outer periphery of the mounting plate 2 along the first direction, and the adjustment components 5 are respectively provided on both sides of the outer periphery of the mounting plate 2 along the first direction; a positioning pin 23 is provided on one side of the outer periphery of the mounting plate 2 along the second direction, the positioning pin 23 is installed on the base plate 1, and the outer periphery of the positioning pin 23 is connected to the mounting plate 2 and the template 3.

[0049] For example, there are two positioning pins 23, and the positioning pins 23 are detachable. When installing the template 3, install the lifting assembly 4 in each installation groove 21, cover the limit plate 22, turn the adjustment bolt 41, so that the universal bearing 43 is higher than the upper end surface of the installation plate 2, install the adjustment assembly 5 in each positioning groove 11, hold the second cantilever 522 and turn the adjustment handle 52 to adjust the position. Figure 4 As shown, the position where the first cantilever 521 and the second cantilever 522 are connected can roughly abut against the circumference of the template 3 during the subsequent installation process, which is equivalent to moving the template 3 on the universal bearing 43 according to a roughly accurate limited position. The positioning pin 23 is installed at the corresponding position on the front side of the base plate 1. First, one end of the template 3 is lifted and placed on the two universal bearings 43 on the rear side of the mounting plate 2, and pushed forward. After the four universal bearings 43 have lifted the template 3, it can be easily pushed forward to the position of the positioning pin 23, indicating that the template 3 is roughly and accurately located above the mounting plate 2. This is conducive to the rapid completion of the fitting installation of the template 3 with the mounting plate 2 through the rolling of the universal bearing 43.

[0050] In some embodiments, two mounting grooves 21 are respectively defined on both sides of the outer periphery of the mounting plate 2 along the first direction, and on the same side, the two mounting grooves 21 are located between the two positioning grooves 11. The two lifting assemblies 4 are located between the two adjustment assemblies 5, which facilitates more labor-saving adjustment of the position of the template 3 on the universal bearing 43 via the handle 52.

[0051] In some embodiments, the adjustment assembly 5 includes a positioning shaft 53, the positioning shaft 53 is connected to the other end of the first cantilever 521, and the outer periphery of the positioning shaft 53 is a cylindrical surface. Figure 4 As shown, after the handle 52 has roughly positioned the template 3 and the template 3 is roughly and accurately located above the mounting plate 2, hold the second cantilever 522 and rotate the handle 52 to adjust the position, as shown in FIG. Figure 5 As shown, the outer circumference of one end of the first cantilever 521 is abutted against the circumference of the template 3. By rotating the positioning shaft 53, the cylindrical outer circumference of the positioning shaft 53 can fine-tune the position of the template 3, which is beneficial for the handle 52 to achieve precise positioning of the template 3.

[0052] In some embodiments, the adjustment assembly 5 includes fixing nuts 54, which are disposed on upper and lower sides of the first cantilever 521 relative to the positioning shaft 53, and the positioning shaft 53 is threadedly connected to the fixing nuts 54. When installing the template 3, after the positioning shaft 53 has been finely adjusted, it can be fixed with the fixing nuts 54 to prevent the adjusted position of the template 3 from changing in the horizontal direction during subsequent processes.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
