Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine mold installation technology, specifically an automatic die-cutting machine mold installation mechanism. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, bonding, and automatic waste removal of various non-metallic materials, self-adhesive labels, double-sided tapes, electronic and mobile phone pads, etc. Die-cutting machines require the use of an installation mechanism during installation.

[0003] Currently, existing die-cutting machine molds are fixed using two methods during installation: First, double-sided tape is used for fixation. The advantage is simple and quick operation. Disadvantages include difficulty in removing the mold after production, easy damage during removal, inaccurate positioning, and increased mold adjustment time. Second, positioning pins and double-sided tape are used for fixation (e.g.,...). Figure 10 The advantages are simple and fast operation and accurate positioning. The disadvantages are: difficulty in removing the mold after production, easy damage to the mold during removal, and the mold plate is designed with fixed size, resulting in a large mold plate and increased mold cost.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] The present invention provides a structure for an automatic die-cutting machine mold mounting mechanism, as shown in the following figure. Figures 1 to 4 As shown, the device includes a mold base plate 1, with several through holes 11 at the center of its surface. A mold fixing plate 2 is placed on the surface of the mold base plate 1, with several fixing through holes 21 at the center of its surface. The mold base plate 1 is 20mm thick, and the mold fixing plate 2 is made of stainless steel with a thickness of 3mm. Both the base plate through holes 11 and the fixing plate through holes 21 have 12 holes each, divided into two groups of 6 holes each. The two groups of base plate through holes 11 and fixing plate through holes 21 are symmetrical about the center lines of the mold base plate 1 and the mold fixing plate 2, respectively. The cross-sectional shape of the base plate through holes 11 is trapezoidal, and the inner diameters of the base plate through holes 11 are 15mm and 10mm, respectively. The diameter of the fixing plate through holes 21 is 8mm.

[0031] The mold pad 1 and mold fixing plate 2 of this utility model can be made of any material and have any thickness. The through hole 11 of the pad is located at the center of the mold pad 1, which can ensure that the mold is installed at the center point of the die cutting pressure of the machine each time, and quickly ensure the balance of the die pressure. At the same time, the size and position of the through hole 11 of the pad are standardized and modularly designed, which can be used with molds of different sizes.

[0032] The 21-position trapezoidal structure of the fixing plate in this utility model has a diameter of 10mm and 15mm to make way for the structure of the fixing bolt 3; the 8mm diameter opening of the fixing plate through hole 21 is to ensure positioning accuracy and ensure that the position of the mold is consistent each time it is installed.

[0033] Furthermore, such as Figure 5 as well as Figure 9 As shown, a fixing bolt 3 is installed inside the through hole 11 of the pad plate, and a locking screw 4 is installed inside the through hole 21 of the fixing plate. The locking screw 4 is connected to the fixing bolt 3. The fixing bolt 3 is composed of a pad plate mating section 31, a coarse positioning mating section 32, and a fixing plate mating section 33. The pad plate mating section 31, the coarse positioning mating section 32, and the fixing plate mating section 33 are integrally injection molded from bottom to top. The dimensions of the pad plate mating section 31, the coarse positioning mating section 32, and the fixing plate mating section 33 are 15mm*5mm, 12mm*15mm, and 8mm*8mm in diameter, respectively. A through screw hole 301 is provided at the center of the fixing bolt 3. The inner diameter of the screw hole 301 is 4mm, and the locking screw 4 is screwed to the screw hole 301.

[0034] The fixing plate mating section 33 of the fixing bolt 3 in this utility model has a diameter of 8mm and a height of 8mm. It is mainly a tight positioning mating section between the mold and the mold fixing plate 2, with an accuracy error range of -0.02mm. The coarse positioning mating section 32 of the fixing bolt 3 has a diameter of 12mm and a height of 15mm. It is mainly a coarse positioning mating section between the fixing bolt 3 and the mold fixing plate 2, with an accuracy error range of +0.05mm. The coarser design of this section is to ensure the strength of the fixing bolt 3. The pad mating section 31 of the fixing bolt 3 has a diameter of 15mm and a height of 5mm. It is mainly a coarse positioning mating section between the fixing bolt 3 and the mold fixing plate 2, with an accuracy error range of +0.05mm. The coarser design of this section serves two purposes: first, to ensure the strength of the T-shaped fixing bolt; and second, to increase the contact area between the fixing bolt 3 and the pressure surface of the machine.

[0035] Working principle: When using, the center position of the die needs to be placed at the center position of the die fixing plate 2. Then, select the two nearest holes on the outside of the die to make holes for fitting with the die fixing plate 2. Next, insert the fixing bolt 3 into the through hole 11 of the pad plate corresponding to the die opening position. During fitting, the fixing plate mating section 33 of the fixing bolt 3 will pass through the two openings of the die. Then, use the locking screw 4 to tighten and fix it with the screw hole 301 in the fixing bolt 3. Finally, the installation of the automatic die cutting machine mold is completed.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
