[0006] Preferably, an upper hard ring is fixedly connected to the edge of the first soft cover, and a lower hard ring is fixedly connected to the edge of the second soft cover. The upper hard ring and the lower hard ring are suitable for clamping the first sealing film and the second sealing film, on the one hand to prevent the liquid paraffin from flowing out, and on the other hand to facilitate the separation of solid paraffin.

[0007] Preferably, the lower hard ring is provided with a plurality of rolling grooves equidistantly arranged around the axis, and a roller is provided in each rolling groove of the lower hard ring, and the rotation axis of the roller is skewed and perpendicular to the axis of the lower hard ring, and the roller rolls along the shrinkage direction of the sealing film.

[0008] Preferably, the lower hard ring is provided with a plurality of groups of shaft frames on the end surface facing away from the second sealing film, the number of the shaft frames corresponds to the rolling groove, and the two shaft frames in the same group are respectively located at the two ends of the rolling groove, and the roller comprises a drum wheel, the outer side surface of the drum wheel protrudes from the end surface of the lower hard ring facing the second sealing film, and the two ends of the drum wheel have end shafts suitable for cooperating with the shaft frames to form a rotating pair, thereby limiting the freedom of movement of the roller.

[0009] Preferably, the lower hard ring is made of metal material, and the end surface of the upper hard ring facing away from the first sealing film is fixedly connected with a magnetic ring, which is suitable for using magnetic attraction to tightly absorb the lower hard ring, thereby compressing the two layers of sealing film between the upper hard ring and the lower hard ring.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By using paraffin wax instead of gypsum as the molding material of the cavity, after solidification, the original specimen for the mold can be taken out without cutting and destroying the structure of the cavity because the texture of paraffin wax is softer. The new replica can also be easily taken out, and the demolding process is simpler, effectively reducing labor costs;

[0014] (2) By wrapping the paraffin in a soft mask, after it melts, workers can squeeze the soft mask to make the paraffin more fully wrap the surface of the original specimen. Therefore, the replica formed by the mold has more detailed features that are closer to the original specimen, effectively improving the quality of the specimen replica.

[0028] like Figure 1-8 The mold for making small reptile and primate specimens using the paraffin method shown in the figure comprises three main parts: an upper mold 1, a lower mold 2 and an electric heating pan 3. The electric heating pan 3 can be one or two. Using one will have a lower cost, while using two will have a higher efficiency. The upper mold 1 comprises a first soft cover 103 made of silicone material. The thickness of the first soft cover 103 is within the range of 1 to 2 mm, which is convenient for extrusion deformation. The first soft cover 103 made of silicone can fully withstand the temperature of paraffin. An upper paraffin core 104 is arranged in the first soft cover 103. It is solid at room temperature and changes into a fluid state when an external heat source is provided. The end face where the opening of the first soft cover 103 is located is covered with a first sealing film 101 made of a PET plastic film. The thickness of the first sealing film 101 is thinner, only about 0.1mm, and it is easier to deform, but the PET plastic film is more resistant to high temperatures, so even if it comes into contact with melted paraffin, about seventy degrees, the first sealing film 101 will not be melted through; the lower half mold 2 also includes a second soft cover 203 made of silicone material, and a lower paraffin core 204 is also arranged in the second soft cover 203. The end face where the opening of the second soft cover 203 is located is covered with a second sealing film 201 also made of PET plastic film. Specimens of small reptiles and primates can be placed between the first sealing film 101 and the second sealing film 201. When the upper paraffin core 104 and the lower paraffin core 204 melt into liquid, they can apply pressure to the first sealing film 101 and the second sealing film 201, so as to fit tightly to the outer surface of the specimen.

[0029] The edge of the first soft cover 103 is fixedly connected with the upper hard ring 102, and the upper hard ring 102 is used to limit the position of the edge of the first soft cover 103. The edge of the second soft cover 203 is fixedly connected with the lower hard ring 220, and the lower hard ring 220 is used to limit the position of the edge of the second soft cover 203. In general, the inner and outer diameters of the upper hard ring 102 and the lower hard ring 220 are equal. In order to allow the upper hard ring 102 and the lower hard ring 220 to clamp the first sealing film 101 and the second sealing film 201, and to ensure that the first sealing film 101 and the second sealing film 201 can be more deformed and moved, the following steps need to be performed. Structural design: A plurality of rolling grooves 221 arranged equidistantly around the axis are provided on the lower hard ring 220, and a roller 250 is provided in each rolling groove 221 of the lower hard ring 220, and the rotation axis of the roller 250 is skewed and perpendicular to the axis of the lower hard ring 220; in order to limit the position of the roller 250, the lower hard ring 220 is also provided with a plurality of groups of shaft frames 222 on the end surface facing away from the second sealing film 201, and the number of groups of the shaft frames 222 corresponds to the rolling grooves 221, and the two shaft frames 222 in the same group are respectively located at the two ends of the rolling groove 221, that is, each rolling groove 221 is located between two shaft frames 222, and the roller 250 has a plurality of groups of shaft frames 222. The main structure includes a drum wheel 251, the outer side surface of the drum wheel 251 protrudes from the end surface of the lower hard ring 220 facing the second sealing film 201, and usually protrudes 0.1 to 0.2 mm to ensure that the second sealing film 201 can directly contact the drum wheel 251, and the second sealing film 201 can also be supported by the end surface of the lower hard ring 220. The drum wheel 251 has end shafts 252 at both ends. The axis of the end shaft 252 is naturally colinear with the axis of the drum wheel 251, and is used to cooperate with the shaft frame 222 to form a rotating pair. The roller 250 can only rotate, and its position relative to the lower hard ring 220 will not change. The lower hard ring 220 is made of metal material, generally an alloy containing iron and nickel elements. The end surface of the upper hard ring 102 facing away from the first sealing film 101 is fixedly connected with a magnetic ring 105, and the lower hard ring 220 is sucked tightly by magnetic force, so that the first sealing film 101 and the second sealing film 201 are clamped between the upper hard ring 102 and the lower hard ring 220. The end surface of the upper hard ring 102 facing away from the first sealing film 101 is provided with a handle 106. There are two handles 106, which are symmetrical with respect to the axis center of the upper hard ring 102, so as to facilitate lifting the upper half mold 1 and realize the release of the adsorption state of the magnetic ring 105 and the lower hard ring 220.

[0030] The electric heating pan 3 is used to heat the upper paraffin core 104 and the lower paraffin core 204. The end face of the electric heating pan 3 has a hot melt groove 301, and the hot melt groove 301 is concave, which is easier to fit the soft cover with a curved surface, can reduce heat loss, and is more energy-efficient when used. The outer side of the electric heating pan 3 is also provided with a handle 302. There are two handles 302, which are symmetrically arranged, so that it is convenient to hold the electric heating pan 3 with both hands to lift it or slide it on the outer surface of the soft cover.

[0031] Working principle: Take two electric heating pans 3 as an example. When using, first let the hot melt groove 301 of the first electric heating pan 3 face upwards, and place the second soft cover 203 of the lower half mold 2 downwards and sit on the lower electric heating pan 3. Place the entire small reptile or the head of a primate to be replicated on the second sealing film 201 of the lower half mold 2, and start the lower electric heating pan 3 to heat the lower paraffin core 204 in the second soft cover 203. After the lower paraffin core 204 completely turns into liquid, gently apply downward pressure to the specimen to make it sink. Since the second sealing film 201 floats on the liquid lower paraffin core 204, the second sealing film 201 will shrink inwards. The upper mold 1 is then placed above the specimen, with the first sealing film 101 of the upper mold 1 facing downward, and the upper wax core 104 in the first soft cover 103 is heated with another electric heating pan 3 to gradually melt the upper wax core 104. In the process of the upper wax core 104 turning into a liquid state, the restraining effect of the first soft cover 103 itself is quickly lost, and the liquid upper wax core 104 presses down the first sealing film 101, causing it to shrink inward and cover the surface of the specimen. At this time, the upper hard circle 102 is tightly attached to the lower hard circle 220 under the magnetic force of the magnetic suction ring 105, and the second soft cover 203 is The greater the pressure, the more it will bulge downward. The upper and lower electric heating pans 3 are removed. The worker squeezes the internal paraffin core through the upper and lower soft covers to make the sealing film completely wrap all the details on the surface of the specimen. Since the liquid paraffin loses the heating and heat preservation effect of the electric heating pan 3, the paraffin will gradually cool down. When you feel that the curing depth of the liquid paraffin is getting bigger and bigger, you can let your hands leave the surface of the soft cover until the paraffin is completely cured and reaches room temperature or lower temperature. Then, you can apply pulling forces in opposite directions to the first sealing film 101 and the second sealing film 201 to separate the upper paraffin core 104 and the lower paraffin core 204. Since the texture of paraffin is softer, Compared with plaster, the specimen can be taken out without destroying its structure. The specimen will form a cavity through the sealing film, and the cavity will have rich details of the specimen. In this way, the cavity on the upper paraffin core 104 and the lower paraffin core 204 can be used to cast curable materials, such as epoxy resin or silicone. After the material is cured, the molded part can be taken out without destroying the paraffin core, and then the two molded parts can be spliced ​​and fixed. Finally, polishing and coloring can be performed to obtain a replica of the original specimen. The replica not only retains the details of the original specimen, but also has a lower production cost and is less susceptible to damage than the original specimen.
