Description

Technical Field

[0001] The utility model relates to the technical field of salt carving forming molds, in particular to a rapid demolding structure of a salt carving forming mold. Background Technique

[0002] With the development of society, the market's pursuit of handicrafts is increasing. Salt carving, as a new popular handicraft, is more and more liked by people in the increasingly commercialized modern society. Currently, salt carving production usually divides a set of molds into an upper mold and a lower mold, and then forms the salt carving.

[0003] Among them, a salt carving forming mold of a Chinese patent, application number <2020208>61840.8>, includes a support frame. A hydraulic pump is fixedly installed at the bottom of the support frame. The bottom of the hydraulic pump is fixedly connected with a connecting block through a hydraulic rod. One side of the connecting block is fixedly connected with a first feeding cylinder. A conical feeding port is arranged at the top of the first feeding cylinder. The surface of the first feeding cylinder is fixedly connected with a fixing plate through a flange. By arranging the conical feeding port at the top of the feeding cylinder in the utility model, large-particle foreign matters in the material can be intercepted. By arranging a mixing box, the material inside the mixing box is stirred and mixed through the output end of the motor, which facilitates the forming of salt carving, is beneficial to improving the forming efficiency and the convenience of using the device. Through the operation of the hydraulic pump, the upper template is driven to move through the connecting block. At this time, the pressure on the lower template decreases, and the compression spring can assist in supporting the lower template, thereby being beneficial to the demolding of the salt carving forming.

[0004] In the above patent, the demolding mainly relies on the cooperation of the compression spring and the hydraulic pump, relying on the elastic restoring force of the compression spring. The demolding speed is slow and the efficiency is low. If the force application points of the compression spring are uneven, it will cause excessive local force on the salt carving and damage it. Therefore, we propose a rapid demolding structure of a salt carving forming mold. Content of the Utility Model

[0027] Example 1

[0028] like Figure 1-4As shown, this utility model provides a technical solution: a quick demolding structure for a salt carving mold, including an operating table 1, a lower template 2 on the top of the operating table 1, an intermediate template 201 pressed against the top of the lower template 2, an upper template 202 on the top of the intermediate template 201, a support frame 3 fixedly connected to the top of the operating table 1 and located behind the lower template 2, a fixed seat 4 below the support frame 3, feeding hoppers 401 on both sides of the top of the fixed seat 4, a mixing tank 402 below the fixed seat 4, and a hydraulic cylinder 301 on the top of the support frame 3. One end of the hydraulic cylinder 301 extends from the bottom of the support frame 3 and connects to the bottom of the fixed seat 4. The hydraulic cylinder 301 is located on the top of the support frame 3 and is connected to the fixed seat 4 through the extended piston rod, providing stable pressure to the mold and ensuring the stability of the mold during the injection and molding process. At the same time, the precise control of the hydraulic cylinder 301 can ensure the tight fit of the mold, prevent salt leakage, and improve the molding quality. The mixing tank 402 is fixedly connected to both sides with first connecting rods 6. The top end of each first connecting rod 6 is connected to the fixed seat 4, and the first connecting rods 6 connect the mixing tank 402 to the fixed seat 4. The fixed base 4 is firmly connected, enhancing the overall stability of the structure. A second connecting rod 601 is fixedly connected to the bottom of the fixed base 4 and to the outside of the first connecting rod 6. One end of the second connecting rod 601 is fixedly connected to the upper template 202. A first drive motor 4021 is installed on the outer wall of the mixing tank 402. The output end of the first drive motor 4021 is connected to a stirrer 4022 located inside the mixing tank 402. The first drive motor 4021 drives the stirrer 4022 to rotate inside the mixing tank 402, achieving uniform mixing of the salt and ensuring that the salt is mixed evenly. The process ensures thorough stirring and mixing, thereby improving the uniformity and quality of the salt sculpture. A connecting pipe 403 is provided between the feed hopper 401 and the mixing tank 402. The bottom of the mixing tank 402 is provided with an outlet pipe 404 that is connected to the upper template 202. A switch valve 4041 is provided on the outlet pipe 404. The feed hopper 401 is connected to the mixing tank 402 through the connecting pipe 403, which facilitates the injection of salt into the mixing tank 402. At the same time, the outlet pipe 404 at the bottom of the mixing tank 402 is connected to the upper template 202, and the flow of salt is controlled by the switch valve 4041.

[0029] Example 2

[0030] like Figure 1-4As shown, a quick demolding structure for a salt carving mold is provided. An ejector plate 203 is located at the bottom of the lower mold plate 2. A demolding assembly 5 is located at the bottom of the operating table 1 and connected to the ejector plate 203. The demolding assembly 5 includes a fixed bracket 501, a second drive motor 502 at the bottom of the fixed bracket 501, and a threaded rod 503 at the top of the fixed bracket 501. A movable sleeve 504 is threadedly connected to the threaded rod 503. One end of the movable sleeve 504 is connected to the top of the ejector plate 203. The output end of the second drive motor 502 is connected to the threaded rod 504. 3. The bottom end is connected; the threaded rod 503 is threadedly connected to the movable sleeve 504. The second drive motor 502 drives the threaded rod 503 to rotate, so that the movable sleeve 504 moves vertically on the fixed bracket 501, thereby driving the ejector plate 203 to eject the salt sculpture from the mold. The structure is simple and the demolding is stable, which significantly improves the demolding efficiency and the integrity of the salt sculpture. The multiple support legs 7 and the base 701 set around the bottom of the operating table 1 can provide stable support and load-bearing capacity, ensuring the stability of the mold during the injection, molding and demolding process.

[0031] The working process of this utility model is as follows: When using a quick demolding structure for a salt carving mold, firstly, an appropriate amount of salt is poured into the feeding hopper 401 for mixing. The first drive motor 4021 is started, driving the stirrer 4022 to rotate inside the mixing tank 402. The salt enters the mixing tank 402 from the feeding hopper 401 through the connecting pipe 403 and is evenly mixed under the stirring of the stirrer 4022. After mixing is completed, the switch valve 4041 on the outlet pipe 404 is opened, and the mixed salt flows into the mold cavity between the upper mold plate 202 and the lower mold plate 2 through the outlet pipe 404. The piston rod of the hydraulic cylinder 301 is adjusted as needed, and the mold is subjected to pressure through the fixed seat 4. Appropriate pressure ensures a tight fit between the mold and the salt material, preventing leakage. Hydraulic cylinder 301 maintains pressure on the mold to ensure the quality of the salt sculpture's molding. Once the salt sculpture is fully cured, hydraulic cylinder 301 gradually releases pressure, preparing for demolding. The second drive motor 502 is started, driving the threaded rod 503 to rotate. Due to the threaded connection between the threaded rod 503 and the movable sleeve 504, the movable sleeve 504 moves vertically upward on the fixed bracket 501. The movable sleeve 504 drives the ejector plate 203 to move upward, thereby ejecting the salt sculpture from the mold. After demolding, the second drive motor 502 is turned off, and the salt sculpture is removed from the operating table 1 for further processing or display.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
