[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] In this embodiment, if Figure 1-Figure 7As shown, the nail-removed latex pillow mold includes a mold support plate 11, a lower mold base 16, and an upper mold base 28. Support legs 12 are symmetrically fixed on the left and right sides of the upper end of the mold support plate 11, the lower mold base 16 is installed on the upper end of the support legs 12, the upper end of the lower mold base 16 is installed on the upper end of the upper mold base 28, and an injection pipe 29 is fixedly installed on the upper end of the upper mold base 28. The lower mold base 16 and the upper mold base 28 are detachably connected, such as hinged.

[0031] A movable plate 13 is installed between the mold support plate 11 and the lower mold base 16. A plurality of pins 27 are fixedly installed on the upper end of the movable plate 13. A plurality of lower mold pin holes corresponding to the pins 27 are opened at the lower end of the lower mold base 16. The plurality of pins 27 slide through the lower mold pin holes and extend to the interior of the lower mold base 16.

[0032] The nail-removing latex pillow mold also includes a nail-removing structure, which is arranged between the movable plate 13 and the lower mold base 16 and is used to adjust the position of the pin 27 so that it extends into the lower mold base 16 or withdraws from the lower mold base 16.

[0033] The nail-removing latex pillow mold also includes a guide structure, which is arranged at the upper corner of the movable plate 13. The guide structure is slidably arranged on the inner wall of the lower mold base 16 to guide the movable plate 13 and the pin 27 to move up and down.

[0034] In this embodiment, the mold support plate 11 is placed on a stable workbench, and the upper mold base 28 is installed on the upper end of the lower mold base 16, and the two are combined to form a complete latex pillow mold cavity.

[0035] The pin 27 enters the lower mold base 16 through the lower mold pin hole; the liquid latex is injected into the mold cavity through the injection tube 29 at the upper end of the upper mold base 28 until the latex completely fills the mold cavity; after curing is completed, the pin withdrawal structure is started; under the action of the pin withdrawal structure, the pin 27 begins to slowly withdraw from the lower mold pin hole; during the pin withdrawal process, the guide structure ensures that the movable plate 13 moves smoothly and in the correct direction; when all the pins 27 are completely withdrawn, the upper mold base 28 is gently lifted to separate the latex pillow from the upper mold base 28; the molded latex pillow is taken out from the lower mold base 16 to complete the demolding process.

[0036] Example 2

[0037] In this embodiment, the nail withdrawal structure is further optimized.

[0038] like Figure 1-Figure 7As shown, the nail withdrawal structure includes two racks 18, a handle 35 is provided on the upper part of one side of the rack 18, the two racks 18 are symmetrically slidably installed on the front and rear sides of the lower end of the lower mold base 16, the lower end of the rack 18 is meshed and connected with two gears 19, the positions of the two gears 19 are symmetrical, one end of the gear 19 is rotatably connected to the cam support seat 21, the cam support seat 21 is fixedly installed at the lower end of the lower mold base 16, the other end of the gear 19 is fixedly connected to the cam 22 through a movable shaft 20, a movable pin 24 is installed at the bottom of the end of the cam 22 away from the movable shaft 20, the movable pin 24 is slidably installed inside the lower movable seat 23, the lower movable seat 23 is fixedly installed at the lower end of the movable plate 13, and the lower end of the rack 18 is clamped with a limiting component.

[0039] Two racks 18 are symmetrically slidably mounted on the front and rear sides of the lower end of the lower die seat 16. This design ensures the balance and stability of the nail withdrawal action and avoids jamming or damage caused by uneven force on one side. The meshing connection between the rack 18 and the gear 19 realizes the transmission and conversion of power, converting the linear motion (sliding of the rack 18) into rotational motion (rotation of the gear 19), thereby driving the subsequent nail withdrawal mechanism. The gear 19 is fixedly connected to the cam 22 through the movable shaft 20, and the rotational motion of the cam 22 is transmitted to the lower movable seat 23 through the movable pin 24, thereby driving the movable plate 13 to move up and down to realize the nail withdrawal operation.

[0040] Example 3

[0041] In this embodiment, if Figure 1-Figure 7 As shown, the limit assembly includes two limit seats 25, which are fixedly installed on the right side of the upper end of the mold support plate 11, and the front and rear positions of the two limit seats 25 correspond to each other. An active plate 31 is slidably installed inside the limit seat 25, and an active rod 32 is fixedly installed on the upper end of the active plate 31. The outer wall of the active rod 32 is slidably connected to the limit seat 25, and the upper end of the active rod 32 slides through the upper end of the limit seat 25 and is fixedly connected to the limit movable block 26, which matches the rack 18. A fixed plate 34 is fixedly installed on the outer wall of the active rod 32, and the fixed plate 34 is slidably installed inside the limit seat 25 and on one side of the outer wall. The upper end of the fixed plate 33 is fixedly connected to a reset spring 34, and the reset spring 34 can be sleeved on the periphery of the active rod 32. The upper end of the reset spring 34 is fixedly connected to the top of the limit seat 25.

[0042] The limit movable block 26 matches the rack 18 and limits the range of motion of the rack 18 during the sliding process through physical contact interference. This ensures that the rack does not slide excessively during the nail withdrawal action, thereby avoiding mold damage or inadequate nail withdrawal caused by sliding too far. When the nail withdrawal action is completed, the elastic force of the reset spring 34 can push the rack 18 back to the initial position through the active rod 32, the active plate 31, and the limit movable block 26, realizing the automatic reset function.

[0043] Example 4

[0044] In this embodiment, if Figure 1-Figure 3 As shown, the guide structure includes a guide rod 14, which is fixedly installed at the upper corner of the movable plate 13, and an auxiliary plate 17 is fixedly installed on the upper end of the guide rod 14. The outer wall of the guide rod 14 is slidably connected to a lubricating sleeve 15, and the lubricating sleeve 15 is fixedly installed inside a fixed block 30, and the fixed block 30 is fixedly installed on the left and right sides of the lower mold base 16.

[0045] The close cooperation between the guide rod 14 and the lubricating sleeve 15 can ensure the precise positioning of the movable plate 13 during the movement, thereby avoiding problems such as inadequate nail withdrawal or mold damage caused by inaccurate positioning.

[0046] As a preferred embodiment, the lubricating sleeve 15 is made of graphite copper.

[0047] Graphite copper graphite material as a solid lubricant, can form an effective lubricating film under oil-free or low-oil conditions, significantly reducing the friction coefficient and wear between mold components, which is beneficial to the long-term stable operation of the mold and extending its service life.

[0048] As a preferred method, Figure 1-Figure 2 As shown, the taper of the pin 27 is consistent with the taper of the lower die pin hole of the lower die seat 16. By making the taper design of the pin 27 consistent with the taper of the lower die pin hole, a sealed state is achieved to prevent latex from flowing out through the lower die pin hole.

[0049] As a preferred method, Figure 7 As shown, spacing grooves are provided on four sides of the upper end of the lower die base 16. By providing spacing grooves on four sides of the upper end of the lower die base 16, the material around the mold is separated to reduce glue overflow.

[0050] As a preferred method, Figure 1-Figure 5 As shown, an anti-skid layer is provided at the bottom of the mold support plate 11. By providing an anti-skid layer at the bottom of the mold support plate 11, the friction between the bottom of the mold support plate 11 and the work surface is increased, thereby preventing the mold from moving during operation and ensuring that the mold can work normally.

[0051] The above embodiment discloses a latex pillow mold for removing nails, wherein the mold support plate 11 supports the lower mold base 16 through the support legs 12, and the upper mold base 28 is installed on the upper end of the lower mold base 16, and the two are combined to form a complete latex pillow mold cavity. The movable plate 13 is installed between the mold support plate 11 and the lower mold base 16, and a plurality of pins 27 are fixedly installed on its upper end, and the pins 27 enter the lower mold base 16 through the lower mold pin holes.

[0052] Liquid latex is injected into the mold cavity through the injection pipe 29 at the upper end of the upper mold base 28 until the latex completely fills the mold cavity.

[0053] The latex gradually solidifies in the mold to form the shape of the latex pillow.

[0054] After curing is completed, the pin withdrawal mechanism is activated. The gear 19 in the pin withdrawal mechanism rotates under the drive of the rack 18, thereby driving the cam 22 to rotate, and the movable pin 24 slides inside the lower movable seat 23, thereby driving the movable plate 13 to descend, and then the pin 27 slowly withdraws from the lower mold pin hole. In this process, the guide structure ensures that the movable plate 13 moves smoothly and in the correct direction.

[0055] After all pins 27 are fully withdrawn, upper die holder 28 is lifted gently to separate the latex pillow from upper die holder 28. Subsequently, the latex pillow of molding is taken out from lower die holder 16 to complete the demoulding process.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
