However, there is no device for demolding between the existing upper mold and the lower mold. When the pressing plate is raised, the upper mold and the lower mold need to be separated from the wooden product manually. Since the upper mold and the lower mold have a certain temperature, during the demolding operation of the upper mold and the lower mold, the gloves cannot effectively isolate the temperature of the upper mold and the lower mold, resulting in the risk of burns to the operator.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] refer to Figure 1-2 As shown, the utility model provides a pressing machine for wood product processing, comprising: an equipment body with a pressing area, in which a pressing plate 3, an upper mold 7 and a lower mold 2 are installed in sequence from top to bottom, the pressing plate 3 is installed above the upper mold 7 for lifting, and the four corners of the bottom of the upper mold 7 are provided with longitudinally retractable split mold assemblies, and the four split mold assemblies are all arranged on the outside of the lower mold 2, so that the upper mold 7 can be moved closer to or away from the lower mold 2 based on the extension and retraction.

[0028] Combination Figure 4 As shown, the mold splitting assembly includes a retractable lifting rod 11 and a support rod 12. The bottom of the support rod 12 is detachably installed in the pressing area away from the bottom of the lifting rod 11. The bottom of the upper mold 7 is respectively placed against the top of the four lifting rods 11. The interior of the support rod 12 is provided with an elastic member for retracting the lifting rod 11.

[0029] As mentioned above, when using the equipment body, pressing plate 3, upper mold 7, lower mold 2 and four mold splitting assemblies provided by the utility model, the upper mold 7 is suspended above the lower mold 2 through the four mold splitting assemblies, and the wooden product is placed on the top of the lower mold 2. At this time, the pressing plate 3 descends, thereby driving the upper mold 7 to press on the wooden product. At this time, the lifting rod 11 in the mold splitting assembly is retracted into the support rod 12 and compresses the spring 14. When the pressing plate 3 is raised, the downward pressure on the upper mold 7 is released. At this time, the elastic force of the spring 14 is released, thereby driving the lifting rod 11 to extend outward on the support rod 12, thereby facilitating the upper mold 7 to be pushed away from the wooden product, thereby realizing the mold splitting operation of the upper mold 7, the wooden product and the lower mold 2, without the need for manual mold splitting.

[0030] Further, in order to facilitate the driving of the lifting rod 11 to telescopically adjust the support rod 12, refer to Figure 4 As shown, the elastic member includes a spring 14, and the spring 14 is longitudinally installed inside the support rod 12. The elastic member can be a spring 14, and the elastic force compressed by the spring 14 plays a parting role between the upper mold 7 and the lower mold 2.

[0031] Further, in order to facilitate the detachable installation of the support rod 12 in the pressing area, refer to Figure 4 As shown, four external thread seats 17 are respectively provided in the pressing area, and the bottom ends of the four support rods 12 are screwed on the corresponding external thread seats 17. The support rods 12 can be detachably installed in the pressing area through the external thread seats 17. After the support rods 12 are removed from the external thread seats 17, the springs 14 in the support rods 12 can be replaced or repaired.

[0032] Further, in order to facilitate the positioning of the upper mold 7 above the lower mold 2, refer to Figure 1 and Figure 3-4 As shown, support seats 10 for positioning are also installed at the four corners of the bottom of the upper mold 7, and a groove 13 for accommodating the top of the lifting rod 11 is opened at the bottom of each support seat 10. When the upper mold 7 is placed on the top of the lifting rod 11 through the groove 13 on the support seat 10, the upper mold 7 cannot be displaced horizontally or vertically, so that it is convenient to guide and position the upper mold 7 above the lower mold 2.

[0033] In the present utility model, combined with Figure 1 and Figure 3 As shown, in the present embodiment, handles 8 for preventing scalding are installed on both symmetrical sides of the upper mold 7 , and a gripping area is provided on the handle 8 , and a rubber ring 9 is wrapped in the gripping area.

[0034] As described above, when the handle 8 provided by the present invention is used, the handle 8 and the rubber ring 9 prevent the operator from directly contacting the upper mold 7, and the upper mold 7 can be easily taken out or put in from the pressing area through the handle 8.

[0035] In the present utility model, combined with Figure 4 As shown, the support rod 12 of this embodiment is also equipped with an adjustment mechanism for adjusting the longitudinal compression stroke of the spring 14 , and the adjustment mechanism is arranged on the top of the external thread seat 17 .

[0036] Combination Figure 4 As shown, the adjustment mechanism includes a backing plate 15 and a screw rod 16 installed in sequence from top to bottom, the bottom end of the spring 14 abuts against the top of the backing plate 15, and a threaded hole 18 for accommodating the screw rod 16 is longitudinally opened at the top of the external threaded seat 17, and one end of the screw rod 16 at least partially extends into the threaded hole 18.

[0037] As mentioned above, when using the adjustment mechanism provided by the utility model, the pad 15 is screwed into the threaded hole 18 on the external threaded seat 17 through the screw 16, and the screw 16 is rotated in the threaded hole 18 to adjust the height of the pad 15 at the top of the external threaded seat 17, thereby adjusting the installation space of the spring 14 in the support rod 12. When the installation space becomes smaller, the parting force between the upper mold 7 and the lower mold 2 becomes larger. When the installation space becomes larger, the parting force between the upper mold 7 and the lower mold 2 becomes smaller, thereby allowing the equipment to be suitable for different types of molds.

[0038] In the present utility model, combined with Figure 1 As shown, the equipment body of this embodiment includes an operating table 1 and a mounting frame 6 longitudinally installed on the rear side of the operating table 1. The mounting frame 6 is an inverted L-shaped structure. A lifting mechanism for lifting is installed between the mounting frame 6 and the top of the ironing plate 3. The ironing area is formed between the ironing plate 3 and the top of the operating table 1.

[0039] Combination Figure 1 As shown, the lifting mechanism includes a hydraulic cylinder 5 and a mounting plate 4 installed at the bottom end of the hydraulic cylinder 5 , the top end of the hydraulic cylinder 5 is longitudinally mounted on a mounting frame 6 , and the pressing plate 3 is fixedly mounted below the mounting plate 4 .

[0040] As mentioned above, when using the equipment body and lifting mechanism provided by the utility model, the operating table 1 in the equipment body provides an installation position for the mounting frame 6, the lower mold 2 and the external threaded seat 17. The hydraulic cylinder 5 is suspended above the pressing plate 3 through the mounting frame 6, and the pressing plate 3 is installed at the bottom of the hydraulic cylinder 5 through the mounting plate 4. The mounting plate 4 is used to prevent the temperature of the pressing plate 3 from acting on the hydraulic cylinder 5. When the wooden product is placed on the lower mold 2, the hydraulic cylinder 5 is started, driving the pressing plate 3 to descend, thereby driving the upper mold 7 to press on the wooden product, realizing the pressing operation of the wooden product.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
