DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 In an embodiment of the present invention, a compression molding fixture includes a lower molding plate 1 and an upper molding plate 2 arranged in parallel, and a left molding plate 3 and a right molding plate 4 arranged in parallel, wherein the lower molding plate 1 and the upper molding plate 2 are both arranged perpendicularly to the lower molding plate 1, and the lower molding plate 1 and the upper molding plate 2 are both arranged perpendicularly to the upper molding plate 2, and the upper molding plate 2 is provided with a first movable groove 5 for the left molding plate 3 to pass through, and the upper molding plate 2 is provided with a second movable groove 6 for the right molding plate 4 to pass through, and a locking component for fixing the upper molding plate 2 is provided between the upper molding plate 2 and the lower molding plate 1.

[0025] A molding method proposed by the present invention comprises the following steps:

[0026] S1, placing the product to be packaged between the upper forming plate 2 and the lower forming plate 1;

[0027] S2, the pressure retaining buckle 9 is engaged with the engagement groove 12 in place by means of a downward pressure mechanism;

[0028] S3, after the pressure holding is completed, the pressure holding buckle 9 is separated from the engagement groove 12, and the spring 13 will bounce the upper forming plate 2 open;

[0029] S4. Take out the pressed product.

[0030] When in use, the product is placed between the upper molding plate 2 and the lower molding plate 1, and the pressure-maintaining buckle 9 is driven to engage with the engaging groove 12 by the downward pressure mechanism, so that the upper molding plate 2 squeezes the product between the upper molding plate 2 and the lower molding plate 1. After the extrusion is completed, the pressure-maintaining buckle 9 is opened to disengage the pressure-maintaining buckle 9 from the engaging groove 12, so that the upper molding plate 2 rebounds under the elastic restoring force of the spring 13. At this time, the upper molding plate 2 is separated from the product, and the product after compression molding can be taken out. The clamp effectively improves the efficiency and quality of compression packaging.

[0031] In this embodiment, the locking buckle assembly includes a pressure-maintaining buckle 9 provided on the lower forming plate 1 and an engaging groove 12 provided on the upper forming plate 2 and locked with the pressure-maintaining buckle 9, and a pressure-maintaining buckle seat 10 is installed between the pressure-maintaining buckle 9 and the lower forming plate 1. The upper forming plate 2 and the lower forming plate 1 are locked by the engagement of the pressure-maintaining buckle 9 and the engaging groove 12, so that the upper forming plate 2 can extrude the product between the upper forming plate 2 and the lower forming plate 1, thereby improving the efficiency and quality of product packaging.

[0032] In this embodiment, the pressure-maintaining buckle 9 includes a pressure-maintaining buckle body 901 and a limiting platform 903, and a rotating shaft 15 is connected between the pressure-maintaining buckle body 901 and the pressure-maintaining buckle seat 10. By connecting the pressure-maintaining buckle body 901 to the pressure-maintaining buckle seat 10 by the rotating shaft 15, the pressure-maintaining buckle body 901 can rotate around the rotating shaft 15, which facilitates the release of the pressure-maintaining buckle 9 so that the upper molding plate 2 is separated from the product.

[0033] In this embodiment, the second guiding inclined surface 902 is provided on the side of the limiting platform 903 away from the pressure retaining buckle body 901. The engaging block 11 is provided in the engaging groove 12, and the first guiding inclined surface 1101 is provided on one side of the engaging block 11 and is arranged offset with the second guiding inclined surface 902. By providing the engaging block 11 in the engaging groove 12, and providing the first guiding inclined surface 1101 on one side of the engaging block 11 and being arranged offset with the second guiding inclined surface 902, the limiting platform 903 is conveniently engaged with the engaging block 11.

[0034] In this embodiment, a guide rod 7 is provided on one side of the lower forming plate 1 close to the upper forming plate 2, and the guide rod 7 is arranged through the upper forming plate 2. A limiting sleeve 8 is provided on the upper forming plate 2 for the guide rod 7 to pass through. By providing the guide rod 7 on one side of the lower forming plate 1 close to the upper forming plate 2, the provision of the guide rod 7 makes the upper forming plate 2 more stable when moving, so that the upper forming plate 2 has better stability when extruding products.

[0035] In this embodiment, a spring 13 is provided between the limiting sleeve 8 and the lower forming plate 1, and the spring 13 is sleeved on the outer periphery of the guide rod 7. By providing the spring 13 between the limiting sleeve 8 and the lower forming plate 1, the setting of the spring 13 can give the upper forming plate 2 a springing force after the spring 13 is compressed, so as to facilitate the separation of the upper forming plate 2 from the lower forming plate 1 and to facilitate the removal of the product between the lower forming plate 1 and the upper forming plate 2.

[0036] It can be understood that one end of the left forming plate 3 and the right forming plate 4 are both provided with a third guiding inclined surface 14 , and such a configuration can facilitate the extension and retraction of the left forming plate 3 and the right forming plate 4 .

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
