Description

Technical Field

[0001] The utility model relates to the technical field of latex pillow production, in particular to a mold structure with switchable shapes. Background Art

[0002] A latex pillow is a pillow made from natural rubber tree sap through a specific process. It has many advantages, such as good elasticity, breathability, antibacterial and anti-mite properties. Therefore, it has become increasingly popular among consumers in recent years. During the production process of latex pillows, the latex needs to be placed in a mold and heated and steamed before it can be shaped into a latex pillow.

[0003] When currently used, due to the different shapes of latex pillows, multiple sets of molds with different shapes are needed to form latex pillows of different shapes. Although the current molds can change the shape of the molds according to the shape of the latex pillows to be produced, for children, raising the pillows can easily cause damage to the cervical spine. Therefore, children usually use shorter pillows. However, since the depth of the mold is fixed, the height of the latex pillows produced is also fixed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 In an embodiment of the utility model, a shape-switchable mold structure includes a mold shell 1, a cover plate 2, a mold plate 3, and an adjustment mechanism 4. The mold shell 1 is used to manufacture silicone pillows. The top and bottom ends of the mold shell 1 are both open structures. The cover plate 2 is rotatably connected to one side of the top surface of the mold shell 1 by a hinge to cover the top surface of the mold shell 1. A feed hole 21 is opened through the top surface of the cover plate 2. The mold plate 3 is detachably connected to the inside of the mold shell 1 to change the shape of the latex pillow. The adjustment mechanism 4 is arranged at the bottom end of the mold shell 1 to adjust the depth of the mold shell 1 to produce latex pillows of different thicknesses. The adjustment mechanism 4 includes a bottom plate 41. The top surface of the bottom plate 41 is fixedly connected to a bottom support 42 that is slidably sleeved with the inside of the mold shell 1.

[0026] Specifically, first, according to the height of the latex pillow to be produced, the depth of the bottom support 42 entering the mold shell 1 is adjusted, and then the cover plate 2 is used to cover the mold shell 1, and the latex raw material is poured into the mold shell 1 from the feed hole 21, and then placed in a steamer to steam the latex. After the latex is steamed, the mold shell 1 is taken out and the cover plate 2 is opened to take out the molded latex. If latex pillows of different shapes need to be made, the shapes of the multiple mold plates 3 can be replaced by different shapes so that the shapes between the multiple mold plates 3 are the required latex pillow shapes. The device makes latex pillows of different shapes by replacing mold plates 3 of different shapes, thereby realizing the function of one mold for multiple uses, and by changing the depth of the bottom support 42 extending into the mold shell 1, latex pillows of different thicknesses can be made, thereby making the applicability of the device wider.

[0027] Example 1

[0028] like Figure 3 and Figure 4As shown, in this embodiment, the outer side surface of the mold shell 1 is fixedly connected to the fixing frame 12, and the two ends of the top surface of the bottom plate 41 are fixedly connected to the threaded rods 43, and the two ends of the top surface of the fixing frame 12 are penetrated and fixed with threaded sleeves 44 that are screwed with the threaded rods 43 at the corresponding positions. The outer wall of the threaded sleeve 44 is fixedly connected to two one-way bearings 45 that are symmetrical up and down. The outer wall of the one-way bearing 45 is fixedly connected to a roller 46. The outer wall of the roller 46 is wrapped with a pull rope 47. A rubber sleeve is fixedly connected between the two pull ropes 47 at the same height. In the opposite direction to the bearing 45, the top surface of the fixed frame 12 is fixedly connected to the cylindrical sleeve 13, and the bottom surface of the roller 46 is fixedly connected to the fixed ring 48. A spring is provided between the fixed ring 48 and the cylindrical sleeve 13 at the corresponding position. One end of the spring is fixedly connected to the fixed ring 48 at the corresponding position, and the other end of the spring is fixedly connected to the cylindrical sleeve 13 at the corresponding position. The four corners of the top surface of the bottom plate 41 are fixedly connected to a cylindrical scale 49 that slides through the fixed frame 12. The length of the cylindrical scale 49 is the same as the height of the base 42.

[0029] In this embodiment, when it is necessary to adjust the depth of the bottom support 42 inserted into the mold shell 1, the staff can hold one of the rubber sleeves and pull it to make the two pull ropes 47 at the corresponding position drive the two rollers 46 at the corresponding position to rotate. The rotating rollers 46 can make the threaded sleeve 44 rotate. Since the threaded sleeve 44 is screwed together with the threaded rod 43 at the corresponding position, the rotating threaded sleeve 44 can make the bottom plate 41 drive the bottom support 42 to move, thereby changing the depth of the bottom support 42 inserted into the mold shell 1. Since a clockwork spring is provided between the fixing ring 48 and the cylindrical sleeve 13 at the corresponding position, When the rubber sleeve is released, the two rollers 46 at the corresponding positions return to their original positions under the action of the clockwork springs at the corresponding positions. Due to the action of the one-way bearing 45, the rollers 46 rotating in the opposite direction will not drive the threaded sleeve 44 to rotate, but will only reel in the pull rope 47 at the corresponding position. The staff can hold the rubber sleeve and pull it back and forth to move the base 42 up or down, while holding the other rubber sleeve and pulling it back and forth will reverse the direction of movement of the base 42. The cylindrical scale 49 allows the staff to observe the depth of the base 42 inserted into the mold shell 1, so that the height of the latex pillow produced can be more accurate.

[0030] Example 2

[0031] like Figure 2 As shown, in this embodiment, a threaded hole 31 is provided on the outer side of the template 3 , and a bolt 11 is provided on the outer side of the mold shell 1 to be screwed together with the threaded hole 31 at a corresponding position.

[0032] In this embodiment, the template 3 is fixed to the inside of the mold shell 1 by bolts 11 so that the staff can replace the template 3 according to production needs, thereby producing latex pillows of different shapes.
