Description

Technical Field

[0001] The invention belongs to the field of saddle production, in particular to a replaceable silicone part forming mold suitable for producing various types of silicone saddles and an application thereof. Background Art

[0002] Traditional molds used to produce silicone (GEL) saddles lack a clear separation between the silicone and foam components. Therefore, during the traditional silicone saddle production process, silicone is injected directly into the mold cavity at the arrow mark, while the mold cavity is positioned horizontally. The foam material is then injected, producing a finished saddle with silicone. However, this method has the disadvantage that the liquid silicone flows naturally within the mold cavity, resulting in uncontrolled shapes, such as highly irregular shapes. Furthermore, this method requires a high injection volume, resulting in significant cost. However, the area where silicone actually reduces riding fatigue is typically the left and right sides of the rear end of the saddle, where it meets the buttocks. Therefore, a solution is sought to address the existing process's issues of high silicone raw material consumption, high costs, uncontrollable shape, and relatively heavy product weight. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings of the existing problems, the present invention provides a replaceable silicone partial molding mold and its application suitable for the production of various types of silicone saddles.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A replaceable silicone partial molding mold suitable for the production of various types of silicone saddles, including a leather pressing plate 1 and a lower mold 2 that are arranged in an upper and lower manner. A gap equivalent to the thickness of the saddle leather surface 3 is left at least in the middle between the lower mold 2 and the leather pressing plate 1 to facilitate placing the saddle leather surface 3 therebetween. An inwardly concave silicone injection mold cavity 4 is provided on the upper surface of the lower mold 2, and an inwardly concave vacuum cavity 5 is also provided on the lower surface of the lower mold 2. Several through holes 6 that connect the silicone injection mold cavity 4 and the vacuum cavity 5 are provided between the silicone injection mold cavity 4 and the vacuum cavity 5. The leather pressing plate 1 also has a An opening 13 is provided to fully expose the silicone injection mold cavity 4 on the lower mold, and a lower mold plate 7 that is sealed with the vacuum cavity 5 on the lower mold 2 is detachably provided below the lower mold 2. The lower mold 2 is also provided with a vacuum hole 14 that is connected to the vacuum cavity 5. The outer side of the vacuum hole 14 is connected to a vacuum pump to achieve vacuuming of the vacuum cavity 5, so that the saddle leather surface 3 above the silicone injection mold cavity 4 can be sucked to the bottom of the silicone injection mold cavity 4 by the vacuum negative pressure, thereby pre-injecting silicone on the saddle leather surface 3 according to the shape of the silicone injection mold cavity 4.

[0006] Preferably, the silicone injection mold cavity 4 includes two parts corresponding to the left and right sides of the saddle and the shape of the buttocks.

[0007] As preferred, a sealing ring 8 is arranged between the lower mold 2 and the lower mold plate 7 to seal the cavity formed between the vacuum cavity 5 on the lower mold 2 and the upper surface of the lower mold plate 7.

[0008] As preferred, a plurality of pin holes are arranged on the upper surface of the lower mold 2 to allow pins 9 to be inserted into the pin holes to fix the saddle skin 3, and corresponding long grooves 15 are arranged on the pressing plate 1 to allow the pins 9 to be inserted into the pin holes. By selecting the positions of the pins 9, the front and back positions of the saddle skin can be adjusted to adapt to different sizes or shapes of the saddle skin.

[0009] As preferred, a mold lifting plate 10 is connected to the pressing plate 1 to facilitate lifting of the pressing plate 1, and more preferably, the mold lifting plate 10 is fixed to the pressing plate 1 by screws.

[0010] As preferred, the lower mold 2 is fixed to the lower mold plate 7 by a locking member 16 to achieve detachability, and more preferably, screw holes are arranged on the lower mold 2 and the lower mold plate 7.

[0011] As preferred, the lower mold 2 and the pressing plate 1 are connected by a hinge 11 to achieve opening and closing of the lower mold 2 and the pressing plate 1, and a set of lock structures are arranged on the opposite side of the hinge 11 to allow the lower mold 2 and the pressing plate 1 to be locked together or released as needed. A cylinder 12 is fixed to the lower mold 2 on the side adjacent to the hinge 11, and the movable end of the cylinder 12 is connected to a pin shaft on the side of the pressing plate 1 to facilitate lifting or lowering of the pressing plate 1 by the extension and retraction of the cylinder 12.

[0012] The application also discloses a production method of the saddle skin with silica gel by using the mold.

[0013] 1) Lifting the pressing plate, laying the saddle skin on the upper surface of the lower mold, ensuring that the back of the saddle skin faces upward, and then lowering the pressing plate to press the saddle skin between the pressing plate and the lower mold;

[0014] 2) Opening the vacuum pump connected to the vacuum cavity to tightly adsorb the saddle skin above the silica gel injection mold cavity to the mold cavity wall of the silica gel injection mold cavity arranged on the upper surface of the lower mold due to the negative pressure;

[0015] 3) Inject silicone onto the saddle leather surface adsorbed on the cavity wall of the silicone injection mold as needed, thereby obtaining a saddle leather surface with silicone; then adsorb the saddle leather surface with silicone into a traditional cushion mold, and then inject the foaming material to obtain the desired saddle cushion with silicone.

[0016] The beneficial effects of the present invention are:

[0017] The replaceable silicone partial molding mold suitable for the production of various types of silicone saddles of the present invention has an ingenious structure. By newly designing a set of special silicone injection molds, silicone can be injected only at the required position of the saddle (obtained through design calculation), so that the required silicone cushion can be obtained through a simple process. Specifically, the saddle leather surface is first adsorbed into the mold, and silicone is injected at the required position in the silicone injection mold cavity to obtain a saddle leather surface with silicone. The saddle leather surface with silicone is then adsorbed into a traditional cushion mold, and foaming raw materials are injected to obtain the saddle cushion with silicone that we actually want. In this way, the silicone injection amount can be effectively controlled, and the cost and product weight can be controlled to the greatest extent. Moreover, the saddle leather surface with silicone produced by this silicone mold can be shared by various types and models of products. The mold is modularly designed. According to the requirements of different silicone shapes, this mold only needs to replace the lower mold, and other components can be used universally. The mold has strong versatility and has the following advantages:

[0018] 1. The mold structure is simple, easy to use and the equipment cost is low;

[0019] 2. The lower mold of the mold can be replaced according to different needs to adapt to various application scenarios;

[0020] 3. The desired shape of the silicone during production is controllable and can meet customer customization requirements;

[0021] 4. The amount of silicone injection is less than that of traditional processes, which can effectively reduce costs and reduce resource waste. BRIEF DESCRIPTION OF THE DRAWINGS
