Description

Technical Field

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

[0002] The traditional mold used to produce silicone (GEL) cushions does not partition the silicone and foaming components well. Therefore, when using the traditional silicone cushion production process, the silicone is directly injected into the mold cavity at the arrow. At this time, the mold cavity is placed horizontally, and then the foaming raw material is injected. The finished cushion with silicone is produced. The disadvantage of this method is that the liquid silicone flows naturally in the mold cavity. The shape of the silicone molding is uncontrolled, such as some very irregular shapes. In addition, when doing so, the amount of silicone injection is large, which wastes costs. But in fact, the area where silicone actually relieves riding fatigue is usually the left and right sides of the rear end of the saddle where it contacts the buttocks. Therefore, people hope to find a way to solve the problems of large consumption of silicone raw materials, high cost, uncontrollable shape, and relatively heavy product weight in the existing process. Summary of the invention

A gap equivalent to the thickness of a saddle leather surface 3 is left at least in the middle between the lower mold 2 and the leather pressing plate 1, so that the saddle leather surface 3 can be placed 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. A plurality of through holes 6 connecting 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 cavity 4 on the lower mold, and a lower mold plate 7 is detachably provided below the lower mold 2 and sealed with the vacuum cavity 5 on the lower mold 2. The lower mold 2 is also provided with a vacuum hole 14 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 cavity 4 can be sucked to the bottom of the silicone injection 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 cavity 4.

[0005] Preferably, the silicone injection mold cavity 4 includes two parts corresponding to the shape of the buttocks on the left and right sides of the saddle.

By selecting the position where the pin 9 is inserted, the front and rear adjustment of the fixed position of the saddle leather surface can be realized to adapt to saddle leather surfaces of different sizes or saddle leather surfaces of different shapes.

[0009] Preferably, the lower die 2 is fixed to the lower die plate 7 by a locking member 16 to achieve detachability. More preferably, the lower die 2 and the lower die plate 7 are both provided with bolt mounting holes.

[0010] Preferably, the lower mold 2 and the leather pressing plate 1 are connected by a hinge 11 on one side so that the lower mold 2 and the leather pressing plate 1 can be opened and closed. On the side opposite to the hinge 11, a group of locking structures are provided between the lower mold 2 and the leather pressing plate 1 so that the lower mold 2 and the leather pressing plate 1 can be locked together or loosened as needed.
