[0038] The technical solution of the present invention is further described below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 7 As shown, a combination and mold opening method of a mold-made gourd mold is implemented by a mold-made gourd mold, wherein the mold-made gourd mold includes an inner core and a mold outer sleeve, the inner core and the mold outer sleeve have a taper contact surface, the inner core is installed in the mold outer sleeve, a square head bolt 16 is installed inside the inner core, the square head bolt 16 passes through the mold outer sleeve, and the inner core and the mold outer sleeve are fastened together by a Yuanbao nut 17; specifically, a flat gasket 20 is arranged between the Yuanbao nut 17 and the inner core, and the inner core and the mold outer sleeve are made of transparent plastic material, which is convenient for observing the growth of the gourd therein.

[0040] The inner core comprises an inner core body 1, the outer surface of which gradually decreases in area from top to bottom and is cone-shaped. A central cavity 2, an umbilical hole 3 and an assembly cavity 4 are sequentially arranged in the inner core body 1 from top to bottom. The free end (upper end) of the central cavity 2 is open and is used to place a gourd. The umbilical hole 3 connects the central cavity 2 and the assembly cavity 4 and is used to insert an umbilical needle 18. The free end (lower end) of the assembly cavity 4 is open and is used to place the square head bolt 16. A through hole is arranged inside the square head bolt 16. The umbilical needle 18 passes through the through hole of the square head bolt 16 and enters the gourd in the central cavity 2. The assembly cavity 4 comprises an upper cavity 5 and a lower cavity 6 which are connected to each other. The aperture of the upper cavity 5 is larger than the aperture of the lower cavity 6 and is arranged in a stepped manner. The upper cavity 5 is used to place the head of the bolt, and the lower cavity 6 is used to place the screw of the bolt.

[0041] Furthermore, the inner core body 1 includes the plurality of core shells 7, and the inner surface of each of the core shells 7 is provided with a gourd groove, an umbilical needle insertion groove and an assembly groove from top to bottom. After the plurality of core shells 7 are assembled by means of positioning pins 8 and positioning holes 9, the gourd grooves are connected together to form a central cavity 2, the umbilical needle insertion grooves are connected together to form an umbilical hole 3, and the assembly grooves are connected together to form an assembly cavity 4. Preferably, in the present embodiment, the number of the core shells 7 is 2.

[0042] The mold jacket comprises a jacket body 10 and a handle 14. The handle 14 is arranged on the jacket body 10. A stepped receiving cavity 15 is arranged inside the jacket body 10 (since the mold jacket is made of transparent plastic, the stepped receiving cavity 15 is arranged inside the jacket body 10). Figure 7 The outer surface of the mold jacket can see the internal stepped storage cavity 15, the stepped storage cavity 15 has openings at the upper and lower ends, which are an inlet and an outlet respectively. The inner core installed with bolts is put into the stepped storage cavity 15 from the inlet, and the lower part of the square head bolt 16 passes through the outlet, and the inner core and the mold jacket are fastened by the ingot nut 17.

[0043] Furthermore, the outer sleeve body 10 is stepped and includes an upper body 11, a middle body 12 and a lower body 13 whose outer diameters gradually decrease from top to bottom. The outer surface of the middle body 12 is a hexahedron, and a slot 19 is provided on the outer surface of the lower body 13 for disassembling and assembling the gourd mold and cooperating with the disassembly tool.

[0044] The combination and mold opening method of the mold-making gourd mold comprises the following steps:

[0045] Combination method:

[0046] Step 1, first put the square head bolt 16 into the assembly groove of any core shell 7, put the young gourd into the gourd placement groove of the core shell 7, lead the umbilical needle 18 through the through hole of the square head bolt 16, and insert the needle head into the umbilical eye of the gourd to locate the position of the gourd in the mold, and connect multiple core shells 7 through the positioning pins 8 and the positioning holes 9 to form the inner core body 1, the head of the square head bolt 16 is placed in the upper cavity 5 of the assembly cavity 4, and the screw of the square head bolt 16 is placed in the lower cavity 6 of the assembly cavity 4, and the lower part of the screw passes through the lower cavity 6 to be exposed. At this point, the installation of the inner core is completed.

[0047] Step 2, place the installed inner core with the gourd placed on it into the mold jacket from the entrance of the stepped storage cavity 15 of the jacket body 10, lead the umbilical needle 18 and the square head bolt 16 through the outlet of the stepped storage cavity 15 of the jacket body 10, and expose the lower part of the square head bolt 16, exert downward pressure on the inner core, press the inner core into the mold jacket, and successively put the flat gasket 20 and the ingot nut 17 on the exposed bolt, and tighten the inner core and the mold jacket again through the ingot nut 17, at this time, the lower end face of the head of the square head bolt 16 is close to the lower end face of the lower cavity 6, because the outer wall of the combined inner core and the inner wall of the jacket body 10 are tapered, the two are locked after being combined, and there is no gap between them, which is enough to overcome the outward growth force of the gourd in the inner core, and the mold will not crack due to the swelling of the gourd.

[0048] As the gourd grows bigger and completely fills the central cavity 2 of the inner core, the umbilical needle 18 is pulled out from the exit of the stepped receiving cavity 15. Because the gourd has already filled the central cavity 2, the navel of the gourd will not continue to grow and be displaced after the umbilical needle 18 is pulled out. Because the inner core and the mold jacket are made of transparent plastic, the growth of the gourd in the mold can be observed, and gourds that are growing poorly, rotten, or have failed to fill the mold can be removed in time, thereby improving the success rate of mold-making gourds.

[0049] Mould opening method:

[0050] The mold can be opened on the gourd frame. First, unscrew the ingot nut 17 and the square head bolt 16, remove the flat washer 20, apply an upward thrust to the square head bolt 16, and the upper end surface of the head of the square head bolt 16 contacts the upper end surface of the upper cavity 5, gradually pushing the inner core upward out of the mold jacket. Because the outer wall of the inner core and the inner wall of the mold jacket are taper-matched, after being ejected until the taper fit is released, the inner core can be taken out upward from the entrance of the stepped storage cavity 15, and the multiple core shells 7 of the inner core can be disassembled to expose the gourd that is not yet fully mature. The gourd can continue to grow and lignify on the gourd frame. Since there is no mold wrapped outside the gourd at this time, the gourd is not easy to rot or mildew. It grows naturally outside the mold, the gourd will look better in color and the leather will be better, greatly improving the success rate of mold-making gourds.

[0051] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0052] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0053] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
