[0002] With the development of technology, more and more plastic products are replaced by paper products. For paper products with high aesthetic requirements (such as barreled paper products, cylindrical products, etc.), the preparation accuracy requirements are also correspondingly high. In order to ensure the preparation of high-precision paper products, it is necessary to make several sub-molds (at least including the hot pressing upper mold and the hot pressing lower mold) tightly closed when preparing the paper bottle wet blank hot pressing shaping, and use the internal high-pressure forming technology device to apply outward pressure inside the paper bottle wet blank. The internal high-pressure forming technology device is a device that uses air pressure and hydraulic forming technology. It A process in which ultra-high pressure gas or liquid is applied inside the wet blank so that the wet blank fits tightly against the inner wall of the mold cavity, making the inner and outer wall surfaces of the blank smooth and the wall thickness uniform. The existing wet blank hot pressing shaping device adopts an upper pressing plate and a lower pressing plate to apply force to the hot pressing upper mold and the hot pressing lower mold respectively to make the two molds close together. Since the internal high-pressure forming technology device applies outward pressure inside the paper bottle wet blank, a large gap exists in some areas between the hot pressing upper mold and the hot pressing lower mold after the two are closed, resulting in an obvious mold line on the outside of the prepared paper mold product. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provides a paper bottle mold locking mechanism for locking a hot pressing upper mold and a hot pressing lower mold to reduce the gap between the hot pressing upper mold and the hot pressing lower mold after the two are molded together.

[0042] Furthermore, there are two locking claws c19, which are relatively arranged on both sides of the second locking component c17; there are two locking grooves c5, which are relatively arranged at opposite positions on the inner side walls of the insertion hole c6.

[0043] The utility model can ensure the structural strength of the locking groove c5 and protect the locking groove c5 by arranging the locking groove c5 to be located on the inner side wall of the insertion hole c6; in addition, by arranging two locking claws c19 and two locking grooves c5 matched therewith, two fixing points are provided, thereby improving the locking strength of the first clamping member c3 and the second clamping member c17, and preventing the first clamping member c3 and the second clamping member c17 from loosening after being connected and impacted.

[0046] Specifically, two adjacent tensioning members c13 are arranged so that the angle (wrapped angle) between the first end point and the end point of the first clamping member c3 between the two tensioning members c13 contacting the strip-shaped transmission member c12 is not greater than 90°.

[0047] The rotary drive device c8 has a small number of parts, a simple structure, low cost, and is easy to assemble and maintain. When the strip transmission member c12 is respectively connected to the outer end faces or inner end faces of several driven tooth members c7, the effective contact area between the driven tooth member c7 and the strip transmission member c12 is limited. If the effective contact area between the driven tooth member c7 and the strip transmission member c12 is small, it will lead to the inability to accurately control the rotation of the first clamping member c3.

[0052] Furthermore, the rotary drive device c8 also includes a tensioning adjustment mechanism c20, which includes a mounting seat c21, a sliding seat c22 and a tensioning wheel c23. The mounting seat c21 is arranged on the hot pressing upper mold d1, and the tensioning wheel c23 is arranged on the mounting seat c21 through the sliding seat c22 and is in the same horizontal plane as the strip transmission member c12. The tensioning wheel c23 presses against the outer end face or inner end face of the strip transmission member c12. A slide groove c30 is provided on the sliding seat c22 or the mounting seat c21, and the sliding seat c22 and the mounting seat c21 are fixedly connected by a fastener c24 inserted into the slide groove c30.

[0053] The sliding seat c22 is provided with a slot (not shown in the figure) arranged along the length direction, and the axis of the tensioning wheel c23 is set in the middle of the slot. This setting method can use the left and right side walls of the slot to limit the two sides of the tensioning wheel c23 to prevent the tensioning wheel c23 from swinging to both sides and affecting the tensioning adjustment effect.

The adjusting component c26 is horizontally screwed on one end of the adjusting component fixing seat c27 facing the sliding seat c22. The adjusting component c26 is used to apply a force to the sliding seat c22 in the direction of pushing the strip transmission member c12.

[0056] The setting of the tensioning adjustment mechanism c20 can ensure that the strip-shaped transmission member c12 remains tensioned, thereby preventing the loosening of the strip-shaped transmission member c12 from affecting the rotation drive device c8 in driving the first clamping member c3 to rotate.

[0057] Furthermore, the upper locking mold part c1 also includes an upper locking mold frame c2, which is installed on the upper end surface of the hot pressing upper mold d1, and a plurality of first locking mold components c3 and a rotation drive device c8 are located on the upper locking mold frame c2, and the first locking mold component c3 can be axially rotated relative to the upper locking mold frame c2; the lower locking mold part c15 also includes a lower locking mold frame c16, which is installed on the lower end surface of the hot pressing lower mold d2, and a plurality of second locking mold components c17 are located on the lower locking mold frame c16.

If the lower end surfaces on both sides of the locking claw c19 are right angles, when the locking claw c19 and the locking groove c5 The engaging surface is not in the same plane (the engaging surface of the locking groove c5 is closer to the bottom wall of the insertion hole c6 than the engaging surface of the locking claw c19), the locking claw c19 cannot be engaged with the locking groove c5.

When the wet paper bottle blank is hot pressed and shaped, no obvious mold line will appear at the position of the mold area corresponding to the upper hot pressing mold d1 and the lower hot pressing mold d2 on the outer side of the wet paper bottle blank, thereby improving the aesthetics of the product;

[0063] (2) The existing wet blank hot pressing shaping device is not equipped with a locking mechanism suitable for locking the internal high-pressure mold, resulting in poor quality of the finished product.

In addition, after the hot pressing shaping is completed, the rotary drive device c8 drives the mold locking member on the mold locking part to rotate again, so that the hot pressing upper mold d1 and the hot pressing lower mold d2 can be quickly separated and released;

[0065] (4) The contact surface between the locking claw c19 and the locking groove c5 of the utility model can be set to a plane, that is, the rotation drive device c8 can drive the locking member on the locking mold member to rotate in one direction to achieve repeated locking and unlocking, and it is convenient to independently adjust the contact surface of the locking claw c19 and the locking groove c5 to obtain a unified locking surface;

[0066] (5) The first clamping member c3 and the second clamping member c17 are arranged in a symmetrical structure, so that the mold is evenly stressed at all locations, can withstand a large clamping force, and make the wall thickness of the product uniform.
