Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a gourd growth molding mold. Background Art

[0002] With the continuous development of agricultural production, people's requirements for agricultural artworks are increasing. When the gourd matures, its surface is hard and shiny, which can be preserved and appreciated for a long time, and can also be used as a utensil. It has been very popular since ancient times. For this reason, some people take advantage of the plasticity of the gourd's growth process. After the gourd grows to a certain stage, it is covered with a mold, and the gourd can be given a variety of shapes through the different shapes of the mold.

[0003] At present, the molds used in the process of gourd growth and molding all have shortcomings. For example, CN201131191Y discloses a gourd growth and molding mold. Due to the large expansion force of the gourd during growth, the limited number of joints cannot ensure the stability of the mold. At the same time, a gap will be formed at the joint of the two sub-molds, which is also easily stretched open. During the growth process of the gourd, it will grow into the gap or the position where the gap is stretched open, and a bulge will be formed on the surface, causing a deformed shape and reducing the yield rate. For example, CN203692024U discloses a growth and molding mold for a human-shaped gourd. During the growth process, the gourd is completely sealed in the mold. The growth state of the gourd cannot be observed at any time during the growth, and the gourd is likely to break the mold. On the one hand, it causes damage to the mold, resulting in waste and increased costs. On the other hand, after the mold is damaged, the gourd will grow along the damaged position, forming a bulge on the surface, reducing the yield rate. At the same time, when the mold is put on the gourd, it is necessary to use a large number of bolts to fix them one by one, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a gourd growth forming mold, which can effectively control the growth of the gourd. The mold is easy to install and is relatively stable and not easy to fall off, thereby preventing the gourd from growing along the joints or damaged parts of the mold, preventing the gourd from being deformed, and improving the yield rate. The mold is not easily damaged, and if the gourd is too large, it is easy to observe, disassemble and replace, thereby reducing waste.

[0005] The technical solution of the utility model is as follows:

[0006] A gourd growth forming mold, the mold comprises two sub-molds, the mold comprises an end portion and a middle portion, the middle portion has a larger diameter, and the end portion has a smaller diameter; a fixing groove is arranged on the outer surface of the end portion, and a fixing piece is arranged in the fixing groove; the middle portion comprises a plurality of strip-shaped arc parts, there is a gap between adjacent strip-shaped arc parts, and both ends of the strip-shaped arc parts are respectively connected to the end portion; there are two end portions, the end portions are hollow cylinders, a supporting plate is arranged on the end surface of one end portion close to the middle portion, and a circular hole is arranged in the center of the supporting plate; the joint seam formed by the two sub-molds forming the mold is not on the same straight line as the strip-shaped arc parts.

[0007] Preferably, the two sub-moulds are connected by snap-fitting to facilitate installation.

[0008] Further preferably, a protrusion and a groove adapted to the protrusion are respectively provided on both sides of the end of the split mold.

[0009] Further preferably, bosses are provided at positions near the joints on the outer surfaces of the ends of the split molds, and protrusions and grooves adapted to the protrusions are provided on the bosses.

[0010] Preferably, an extended arc surface is provided at one end of the end portion close to the middle portion.

[0011] Preferably, the diameter of the middle part changes from small to large and then to small. Further preferably, the maximum diameter position of the middle part is close to the end where the support plate is set, and is designed according to the shape of the body of the gourd, which is more conducive to the growth and shaping of the gourd.

[0012] Preferably, the outer and inner diameters of both ends of the mould are the same.

[0013] Preferably, the fixing member is a buckle or a throat clamp.

[0014] Preferably, at least one strip-shaped arc-shaped component is provided on the split mold.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. By setting the clamping connection between the sub-molds and the coordination of the fixing grooves and the fixing parts, it is not only convenient for the mold to be put on the gourd for operation, but also conducive to the stability of the mold. It is also convenient to disassemble the mold and reuse it. In the process of gourd growth, if it is found that the mold selection is not suitable, the mold can be disassembled and replaced with a new one by controlling the fixing parts, and the replacement is also more convenient.

[0017] 2. By setting the strip-shaped arc parts, it is convenient to set the shape of the gourd, and the growth status of the gourd can be intuitively seen. There are gaps between the strip-shaped arc parts. Even if the gourd grows too large, the gourd can grow towards the gaps. Growing towards the gaps is more conducive to the growth and shaping of the gourd. It is not easy to break the mold or grow into a special shape, which reduces waste, effectively controls costs, and improves the pass rate.

[0018] 3. The middle part is where the gourd is located or formed. The strip-shaped arc-shaped parts and the splicing seams are not on the same straight line. The splicing seams of the mold are set above and below the body of the gourd. The splicing seams will not affect the growth of the gourd and the final forming of the gourd.
