Description
Technical Field
[0001] The present invention relates to the technical field of sculptures, in particular to a production process of a large-scale sculpture made of new materials. Background Art
[0002] Sculpture refers to ornamental objects and monuments carved to enhance the environment or commemorate events, bearing meaning, symbolism, or pictographic forms. Sculpture is a form of plastic art. Also known as carving, it encompasses three creative methods: engraving, carving, and shaping. It involves using various plastic materials (such as plaster, resin, and clay) or hard materials that can be carved or engraved (such as wood, stone, metal, jade, agate, aluminum, fiberglass, sandstone, and copper) to create visual and tangible artistic images within a defined space. These images reflect social life and express the artist's aesthetic perceptions, emotions, and ideals. While carving and engraving reduce the amount of material available for carving, shaping achieves its artistic purpose by increasing the amount of plastic material.
[0003] Currently, due to their sheer size, large sculptures are typically manufactured in factories from separate components, assembled and transported together. This results in high costs and the sculptures often risk damage during assembly and transportation. Furthermore, large sculptures produced in pieces and assembled on-site are prone to warping and cracking at the joints after a period of display, which degrades the sculpture's appearance. The sculptures are prone to fading over time, are difficult to transport, and are difficult for visitors to touch. This significantly limits their display options and methods. Summary of the Invention

[0023] As a preferred embodiment of the present invention, in step 600, the top of the gypsum mold after being assembled and wrapped with the silicone soft mold is determined according to a preset shape, and a feed opening is set on the gypsum hard mold and the silicone soft mold corresponding to the top end, and the second gypsum mixture is poured into the gypsum mold from top to bottom through the feed opening.
[0024] As a preferred solution of the present invention, in step 600, a plurality of support frames are provided on the outside of the complete plaster mold, and the support positions of the plurality of support frames are the splicing positions of two adjacent plaster hard molds.

Obviously, the drawings described below are merely exemplary, and those skilled in the art can derive other implementation drawings based on the provided drawings without inventive effort.
[0035] Figure 1 A production process flow chart provided for an embodiment of the present invention. DETAILED DESCRIPTION
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0037] like Figure 1 As shown, the present invention provides a production process for large-scale new material sculptures. Unlike the traditional large-scale sculpture production method that requires cutting the sculpture into several pieces after production and then splicing the sculpture at the installation site, the present application cuts the gypsum hard mold into several hard mold units, and the several hard mold units can be transported to the installation site to produce the sculpture at the installation site. The sculpture produced by the production process of the present application is a complete whole, and the installation and construction are quick, eliminating the risk of damage during transportation.
[0038] The specific steps include:
[0039] Step 100: Create a clay mold according to the pattern and shape of the sculpture.
[0040] Step 200: Brush liquid silicone on the clay mold to form a silicone soft mold with partitions on the surface of the clay mold, and set partition slices on the liquid silicone.
[0041] In step 200, the thickness of the partition slices is small, and the insertion depth of the partition slices is less than the brushing thickness of the liquid silicone, wherein the partition slices distributed along the height direction of the mud mold are used to cut off the first gypsum mixture to generate a plurality of gypsum hard molds that are segmented from top to bottom. The segmented gypsum hard molds are connected by embedded parts when forming the sculpture body to improve the fixity of the entire sculpture.
[0042] The partition slices distributed along the positions with fewer characteristic elements of each gypsum hard mold are used to divide each section of the gypsum hard mold into at least two hard mold units, so as to facilitate the demoulding and removal of the hard mold units from the surface of the silicone soft mold.
[0043] Among them, it should be added that the silicone soft mold has good integrity and the mud mold is not adhered to the plaster hard mold made subsequently, which facilitates the subsequent demoulding and separation of the plaster hard mold from the mud mold.
[0044] The thickness of the silicone soft mold is 3-6mm. The silicone soft mold has good elasticity and sealing properties, which makes it easy to lay the silicone soft mold on the spliced plaster mold in the subsequent process.
[0045] Step 300: Gypsum powder, glass fiber and water are mixed to form a first gypsum mixture, and multiple layers of the first gypsum mixture are applied to the surface of the silicone soft film. After the first gypsum mixture is cured, an automatically segmented gypsum hard mold is formed, and each segment of the gypsum hard mold is composed of multi-dimensionally segmented hard mold units.
[0046] When producing a three-dimensional sculpture, a silicone soft film with an integrated structure is formed on the surface of the clay mold, and is decomposed into multiple plaster hard molds in the height direction of the clay mold. Each plaster hard mold is composed of at least two hard mold units, so that the hard mold units are easily demolded from the surface of the silicone soft film.
[0047] Step 400: demold and remove the hard mold unit and the silicone soft mold from the clay mold respectively, set a binding mechanism on the connecting end faces of two adjacent hard mold units to form a single-segment plaster hard mold, and construct an embedded body on the connecting end faces of the two adjacent plaster hard molds to form a complete plaster mold of the corresponding sculpture body.
[0048] In step 400, the plaster hard mold is first demoulded and removed from the silicone soft mold in pieces and sections, and then the silicone soft mold is cut so that the silicone soft mold can be demoulded and removed from the clay mold without deformation.
[0049] The steps for implementing the arrangement of a binding mechanism on the connecting end surfaces of two adjacent hard mold units to form a single-segment plaster hard mold are as follows:
[0050] The hard mold units of each section of the gypsum hard mold are classified and stored, and fixing straps and mounting buckles are respectively provided on the connecting surfaces of two adjacent hard mold units;
[0051] A plurality of the hard mold units are connected by fixing straps and mounting buckles to form a single-segment plaster hard mold.
[0052] In addition, the steps for constructing the embedded body from the connecting end faces of two adjacent gypsum hard molds are as follows:
[0053] Determine in advance the cutting position of the clay mold along the height direction, apply the molding colloid at the cutting position to generate the rubber segment of the splicing area, and cut the rubber segment of the splicing area to demould from the clay mold;
[0054] Hardening the rubber segment in the splicing area;
[0055] The hardened rubber segment in the splicing area is feature-matched and buckled onto the connecting end faces of the two adjacent gypsum hard molds, and a clamp is assembled on the outer surface of the rubber segment in the splicing area to fix and assemble the two adjacent gypsum hard molds.
[0056] Step 500: At the installation site, multiple plaster hard molds are spliced into a complete plaster mold according to the shape of the sculpture, and the silicone soft mold is laid on the surface of the spliced plaster mold according to the shape of the sculpture and fits with the plaster mold.
[0057] The silicone soft mold is laid on the surface of the spliced gypsum mold, and the cut positions of the silicone soft mold are fastened together to make the inner surface of the silicone soft mold fit completely with the gypsum mold.
[0058] In this step, the hardened rubber segment of the splicing area is feature-matched and buckled onto the connecting end faces of the two adjacent gypsum hard molds, and a clamp is assembled on the outer surface of the rubber segment of the splicing area to fix and assemble the two adjacent gypsum hard molds, which can improve the stability of the complete gypsum mold and prevent the gypsum hard mold from tilting and shifting during splicing.
[0059] In addition, the silicone soft mold can further improve the stability of the spliced plaster mold, which is equivalent to adding a tights to the outside of the mold, which plays a certain role in fixing the splicing position of the mold. Of course, you can also add a tripod outside the plaster mold to ensure that the spliced plaster mold will not shift.
[0060] Most existing sculptures are produced, cut into several pieces, transported to the installation site and reassembled to form a complete sculpture. The problem with this sculpture production process is that the sculpture is made up of multiple templates, and if the stress at the splicing position does not meet the requirements, it is easy to break, affecting the service life and aesthetics.
[0061] Different from the prior art, this embodiment divides the mud mold into multiple gypsum hard molds from top to bottom according to the size of the mud mold in the factory, and each gypsum hard mold is composed of at least two cut hard mold units. The transportation process only requires transporting the lighter hard mold units and silicone soft molds, so it is convenient to transport and not easy to be damaged.
[0062] During on-site installation, the raw materials of the sculpture are stirred on-site. Specifically, gypsum powder, resin, curing agent, glass fiber, carbon fiber and water are mixed to form a gypsum mixture, and the hard mold units are first assembled into a gypsum hard mold. Then, the gypsum hard mold is assembled in sequence to form a complete gypsum mold, and a silicone soft mold is set on the outside of the gypsum mold to form a complete and stable gypsum mold with multiple block hard mold units. The gypsum mixture is injected into the gypsum mold. After the gypsum mixture is solidified, the silicone soft mold and hard mold units are disassembled in turn to obtain the sculpture body that has been injected and produced.
[0063] The silicone soft mold and hard mold units can be reused within a certain range of times, so the sculpture can be replicated, making the production of the sculpture simpler and easier.
[0064] Step 600: Prepare a second gypsum mixture, and pour the second gypsum mixture into a complete gypsum mold from top to bottom. After the second gypsum mixture dries and solidifies, a sculpture body is formed. The silicone soft mold and the gypsum mold are removed.
[0065] It should be noted that the production process of the embodiment of the present invention adds glass fiber and carbon fiber to the gypsum powder used to shape the sculpture, which further improves the performance of the gypsum powder and improves the toughness and wear resistance of the produced sculpture. At the same time, it can effectively prevent problems such as cracking and warping on the surface of the sculpture, and improve the overall strength of the sculpture. Large sculptures are usually used outdoors. The strength of the large sculptures produced by this application is optimized, which can extend the time the sculpture is affected by environmental erosion, effectively extend the service life of the sculpture, and avoid quality problems such as cracking and warping of the sculpture during the display process, which affects the appreciation of the sculpture.
[0066] In step 600, the top of the gypsum mold that is assembled and wrapped with the silicone soft mold is determined according to a preset shape, and a feed opening is set on the gypsum hard mold and the silicone soft mold corresponding to the top, and the second gypsum mixture is poured into the gypsum mold from top to bottom through the feed opening.
[0067] When removing the plaster mold, first remove the silicone soft mold, then remove the clamp and the rubber section of the splicing area, and finally loosen the fixing straps and mounting buckles on the hard mold unit of each section of the plaster hard mold.
[0068] Further explanation is provided by providing multiple support frames on the outside of the complete plaster mold. These frames support the joints of two adjacent plaster molds. The support frames are stacked to form a three-dimensional support frame, and the support frames at two adjacent joints are connected by interlocking rods to form a support net for protecting the plaster mold.
[0069] In step 600, the second gypsum mixture is poured from top to bottom into the complete gypsum mold. The second gypsum mixture is dried and solidified to form a sculpture. The implementation method specifically includes the following steps:
[0070] Step 601: mixing gypsum powder, resin, curing agent, carbon fiber, glass fiber and water to prepare a second gypsum mixture;
[0071] Step 602: slowly pour the second gypsum mixture into the complete gypsum mold, and wait for the gypsum slurry layer to solidify and form a sculpture;
[0072] Step 603: removing the silicone soft mold and the plaster mold;
[0073] Step 604: Polish the solidified sculpture until a smooth sculpture is obtained.
[0074] In step 602, a negative pressure port is provided at one side of the feed opening at the uppermost end of the complete gypsum mold, and the second gypsum mixture is poured into the complete gypsum mold through the feed opening. The negative pressure port is connected to a suction pump to maintain negative pressure conditions in the complete gypsum mold, so that the gas in the second gypsum mixture overflows, thereby achieving defoaming treatment of the second gypsum mixture and enhancing the density of the sculpture after solidification.
[0075] This embodiment cuts the gypsum hard mold into several hard mold units, which can be transported to the installation site and the sculpture body can be produced at the installation site. The sculpture body produced by the production process of this application is a complete whole, which is quick to install and eliminate the risk of damage during transportation.
[0076] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
