[0028] like Figures 1-2 As shown, a mold-opening tool for molding gourd molds includes a clamping frame 1 and a movable rod 2. The clamping frame 1 includes an upper horizontal plate 1.1, a lower horizontal plate 1.2, and a vertical plate 1.3 connecting the upper horizontal plate 1.1 and the lower horizontal plate 1.2. A notch 2.2 is opened on the upper horizontal plate 1.1. The movable rod 2 passes through the lower horizontal plate 1.2. A push block 3 is installed at its upper end and a gripping rod 5 is installed at its lower end. A threaded groove 4 is opened on the push block 3, and the threaded groove 4 opens upward.

[0029] The molded gourd mold includes an inner core and a mold outer sleeve 6. The inner core is installed inside the mold outer sleeve 6 and is tapered with the mold outer sleeve. A bolt is installed at the lower part of the inner core, which passes through the mold outer sleeve 6 and is exposed at the bottom. The upper horizontal plate 1.1 is clamped to the outer surface of the mold outer sleeve 6 through a bayonet 2.2. The threaded groove 4 of the push block 3 matches the external thread of the bolt. By rotating the movable rod 2, the push block 3 is tightened onto the bolt, and the push block 3 is pushed upward to push the inner core out of the mold outer sleeve 6.

[0030] Furthermore, a vertical through hole is made on the lower horizontal plate 1.2, and the movable rod 2 is mounted on the lower horizontal plate 1.2 through the through hole.

[0031] Example 2

[0032] Figures 3-8 This embodiment provides the gourd molding mold described in Embodiment 1, including an inner core and a mold outer sleeve 6. The inner core is installed inside the mold outer sleeve 6, and a square head bolt 22 is installed inside the inner core. The square head bolt 22 passes through the mold outer sleeve 6, and the inner core and the mold outer sleeve 6 are fastened together by a nut 23. Specifically, a flat washer 26 is provided between the nut 23 and the inner core. The inner core and the mold outer sleeve 6 are made of transparent plastic material, which facilitates observation of the gourd growth inside.

[0033] The inner core includes an inner core body 7. The outer surface area of ​​the inner core body 7 gradually decreases from top to bottom, forming a cone shape. Inside the inner core body 7, a central cavity 8, a guide hole 9, and an assembly cavity 10 are arranged sequentially from top to bottom. The free end (upper end) of the central cavity 8 is open for placing the gourd. The guide hole 9 connects the central cavity 8 and the assembly cavity 10 and is used to insert a guide needle 24. The free end (lower end) of the assembly cavity 10 is open for placing the square head bolt 22. The square head bolt 22 has a through hole inside. The guide needle 24 passes through the through hole of the square head bolt 22 and enters the gourd inside the central cavity 8. The assembly cavity 10 includes an upper cavity 11 and a lower cavity 12 that are interconnected. The diameter of the upper cavity 11 is larger than the diameter of the lower cavity 12, and they are arranged in a stepped shape. The upper cavity 11 is used to place the head of the bolt, and the lower cavity 12 is used to place the bolt shank.

[0034] Furthermore, the inner core body 7 includes multiple core shells 13. Each core shell 13 has a gourd-placement groove, a needle insertion groove, and an assembly groove on its inner surface from top to bottom. After the multiple core shells 13 are assembled by the cooperation of positioning pins 14 and positioning holes 15, the gourd-placement grooves are connected together to form a central cavity 8, the needle insertion grooves are connected together to form a needle hole 9, and the assembly grooves are connected together to form an assembly cavity 10.

[0035] The mold jacket 6 includes a jacket body 16 and a handle 20. The handle 20 is disposed on the jacket body 16. The jacket body 16 has a stepped storage cavity 21 inside (because the mold jacket 6 is made of transparent plastic, from...). Figure 8 The outer surface of the mold outer sleeve reveals an internal stepped storage cavity 21. The stepped storage cavity 21 has openings at its upper and lower ends, serving as an inlet and an outlet, respectively. An inner core, fitted with bolts, is inserted into the stepped storage cavity 21 through the inlet. The lower part of a square-headed bolt 22 passes through the outlet, and a nut 23 secures the inner core to the mold outer sleeve 6. Furthermore, the outer sleeve body 16 is stepped, comprising an upper body 17, a middle body 18, and a lower body 19, with their outer diameters gradually decreasing from top to bottom. The outer surface of the middle body 18 is hexahedral, and the outer surface of the lower body 19 has a slot 25 for matching with the bayonet 2.2 of the mold opening tool in Embodiment 1.

[0036] Example 3

[0037] like Figures 3-8 This embodiment provides a method for assembling the molded gourd mold described in Embodiment 2, including the following steps:

[0038] Step 1: First, place the square head bolt 22 into the assembly slot of any core shell 13. Place the small gourd into the gourd placement slot of the core shell 13. Pass the umbilical needle 24 through the through hole of the square head bolt 22 and insert its tip into the gourd's navel to position the gourd in the mold. Connect multiple core shells 13 with positioning pins 14 and positioning holes 15 to form the inner core body 7. Place the head of the square head bolt 22 in the upper cavity 11 of the assembly cavity 10 and place the screw of the square head bolt 22 in the lower cavity 12 of the assembly cavity 10. The lower part of the screw protrudes out of the lower cavity 12 and is exposed. The inner core installation is now complete.

[0039] Step 2: Insert the assembled inner core containing the gourd into the mold outer sleeve 6 through the entrance of the stepped storage cavity 21 of the outer sleeve body 10. The guide pin 24 and the square head bolt 22 pass through the outlet of the stepped storage cavity 21 of the outer sleeve body 10, with the lower part of the square head bolt 22 exposed. Apply downward pressure to the inner core to press it tightly into the mold outer sleeve 6. Then, put the flat washer 26 and the ingot nut 23 onto the exposed bolt in sequence, and tighten the inner core and the mold outer sleeve 6 again through the ingot nut 23. At this time, the lower end face of the head of the square head bolt 22 is close to the lower end face of the lower cavity 12. Since the outer wall of the assembled inner core and the inner wall of the outer sleeve body 10 are tapered, after the two are assembled and locked, there is no gap between them, which is sufficient to overcome the outward growth force of the gourd in the inner core and prevent the mold from cracking due to the gourd filling up.

[0040] As the gourd grows and completely fills the central cavity 8 of the inner core, the navel needle 24 is pulled out from the outlet of the stepped receiving cavity 21. Because the gourd has already filled the central cavity 8, the navel of the gourd will not shift due to continued growth after the navel needle 24 is pulled out. Since the inner core and the outer mold 6 are made of transparent plastic, the growth of the gourd inside the mold can be observed, and gourds that are not growing well, are rotten, or have not filled the mold can be removed in time, thereby improving the success rate of gourd molding.

[0041] Example 4

[0042] like Figures 1-8 This embodiment provides a mold-opening method for the mold-opening tool of the molded gourd mold described in Embodiment 1, including the following steps:

[0043] The mold can be opened using a hoist frame. First, unscrew the ingot nut 23 from the square head bolt 22, remove the flat washer 26, and use the slot 2.2 of the upper horizontal plate 1.1 to engage the mold outer sleeve 6, so that the mold opening tool is installed on the mold outer sleeve 6. Rotate the movable rod 2 by holding the rod 5, which drives the push block 3 to tighten onto the square head bolt 22, applying an upward pushing force to the movable rod 2. The upper end face of the head of the square head bolt 22 contacts the upper end face of the upper cavity 11, gradually pushing the inner core upward out of the mold. Set 6, because the outer wall of the inner core and the inner wall of the outer mold 6 are tapered, after the tapered fit is released, the inner core can be taken out from the entrance of the stepped storage cavity 21. The multiple core shells 13 of the inner core are disassembled to expose the gourd that is not yet fully mature. The gourd can continue to grow and lignify on the gourd frame. Since the gourd is not wrapped by the mold at this time, it is not easy for the gourd to rot or become moldy. It grows naturally outside the mold, and the color of the gourd will be better and the skin will be better, which greatly improves the success rate of molded gourds.

[0044] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0045] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0046] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
