[0002] The production mold for silicone products is mainly used to process different specifications of production tools with silicone as the main raw material. Silicone, also known as silicic acid gel, has stable chemical properties and is non-combustible. Therefore, many items in daily life are made of silicone, and most of them are produced by the production mold for silicone products.

[0003] Regarding the existing related technologies, the inventor believes that there are often the following defects: when using a mold to produce silicone products, due to the limitation of the shape of the silicone product, the mold cavity on the mold is arranged in an inward concave state. After the silicone product is formed, part of the silicone product is formed in the inward concave part of the mold cavity. At this time, when discharging, it can only directly pull the silicone product from the top to make it fall off. The hard-pulling type of discharging not only has the risk of breaking the silicone product, but also is not conducive to taking the formed silicone product off the mold. The material taking is relatively inconvenient and the work efficiency is low.

[0027] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification. Embodiment 1

[0028] Referring to Figures 1-5 , which is the first embodiment of the present utility model, a silicone product production mold is provided. Such a silicone product production mold includes a lower die 1 and an upper die 2. The upper die 2 is located above the lower die 1. The lower die 1 includes a die frame 11, and a forming main body 13 is slidably installed in the inner cavity of the die frame 11;

[0029] The forming main body 13 includes a fixed die strip 131 and a movable die strip 132. The movable die strip 132 is fixed at the rear side inside the die frame 11. A group of middle die strips 133 are arranged between the opposite surfaces of the fixed die strip 131 and the movable die strip 132. A row of forming grooves 134 are opened at the front and rear sides of the relative ends of the tops of the fixed die strip 131 and the movable die strip 132 and the top of the middle die strip 133. At the same time, a forming cavity is formed between two adjacent and opposite forming grooves 134.

[0030] Side blocks 135 are welded at the middle parts on both sides of the fixed die strip 131, the movable die strip 132, and the middle die strip 133. A first spring 136 is fixed between the opposite surfaces of two adjacent side blocks 135 on the same side.

[0031] The fixed die strip 131, the middle die strip 133, and the movable die strip 132 are brought together to form a cavity. When the movable die strip 132 moves, the first spring 136 will also be compressed. After the silicone product is formed, the card rod 35 is disengaged from the clamping inside the card hole 16. Under the elastic reset action of the first spring 136, the fixed die strip 131, the movable die strip 132, and the middle die strip 133 are separated and a gap appears, and the silicone product is directly exposed from the concave part of the cavity, which is convenient for unloading the silicone product, with high work efficiency, and also reduces the damage to the silicone product during unloading, improving the production quality.

[0032] Limiting grooves 14 for the side blocks 135 to slide are provided on both sides of the mold frame 11, and the molding body 13 slides between the limiting grooves 14 on both sides. A blocking strip 12 is detachably installed at one end of the mold frame 11 close to the movable mold strip 132. The blocking strip 12 is detachably installed. After the blocking strip 12 is removed, the molding body 13 can be easily removed from the mold frame 11.

[0033] During use, the fixed mold bar 131, the movable mold bar 132 and the middle mold bar 133 on the fixed card 3 are combined together, and a force is applied to the fixed mold bar 131 through the movable mold bar 132, so that the movable mold bar 132 moves toward the fixed mold bar 131 facing the middle mold bar 133, so that the fixed mold bar 131, the middle mold bar 133 and the movable mold bar 132 are close to each other to form a mold cavity. When the movable mold bar 132 moves, the spring 136 is also compressed. When the movable mold bar 132 moves, the fixed card 3 is also driven to move, and the mold cavity is formed;

[0034] The silicone strip is placed above a row of molding grooves 134, the mold is heated to melt the silicone strip, and the upper mold 2 presses down the lower mold 1 to form the silicone product. After the silicone product is formed, the clamping rod 35 is disengaged from the clamping connection inside the clamping hole 16, and under the elastic reset action of the spring 136, the fixed mold strip 131, the movable mold strip 132 and the middle mold strip 133 are stretched open and a gap is formed, and the silicone product is directly exposed from the inner concave part of the mold cavity. Example 2

[0035] Reference Figures 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0036] The movable mold strip 132 is fixedly installed with fixed cards 3 on both sides, and a concave cavity for accommodating the fixed card 3 is provided on the top of the upper mold 2, and a card hole 16 that is engaged with the card end of the fixed card 3 is provided at the bottom of the inner wall of the limiting slide groove 14, and a connecting cavity 15 for the fixed card 3 to pass through is provided on the top of the two side arms of the mold frame 11, and the connecting cavity 15 is connected with the interior of the limiting slide groove 14. When the mold cavity is formed, the card rod 35 and the card hole 16 are in a coaxial state, and the card rod 35 will enter the internal card hole 16 for engagement, and the position of the movable mold strip 132 is positioned and restricted, so that the fixed mold strip 131, the movable mold strip 132 and the middle mold strip 133 can be kept in a state of being close together, so as to avoid the fixed mold strip 131, the movable mold strip 132, and the middle mold strip 133 being forced to move during molding, resulting in a gap between the two close molding grooves 134, thereby ensuring the molded silicone product.

[0037] The fixed card 3 includes a hole block 31 slidably installed inside the limit chute 14. A U-shaped frame 32 passing through the inside of the communication cavity 15 is welded to the top of the hole block 31. A clamping rod 35 is arranged on the U-shaped frame 32 through a through hole opened at its top. The bottom end of the clamping rod 35 passes through the hole on the hole block 31 and enters the inside of the clamping hole 16 for clamping connection. A pull ring plate 34 is welded to the top of the clamping rod 35.

[0038] A convex ring 36 is welded on the outer wall of the clamping rod 35 and inside the U-shaped frame 32. A second spring 33 is sleeved between the top of the convex ring 36 and the top end of the inner wall of the U-shaped frame 32 on the outer wall of the clamping rod 35. Hold the pull ring plate 34 and pull the clamping rod 35 upward to disengage the clamping rod 35 and the universal ball 37 from the clamping hole 16. At the same time, the convex ring 36 compresses the second spring 33. When the pulling force on the pull ring plate 34 is released, under the elastic action of the second spring 33, the clamping rod 35 is reset downward, and clamping connection is carried out by means of elastic clamping, which facilitates the quick clamping connection or disengagement between the clamping rod 35 and the clamping hole 16.

[0039] A universal ball 37 is welded at the center of the bottom of the clamping rod 35, and the size of the universal ball 37 is smaller than the diameter of the clamping rod 35. The universal ball 37 rolls inside the limit chute 14, which is beneficial to reducing the friction during movement.

[0040] During use, hold the pull ring plate 34 and pull the clamping rod 35 upward to disengage the clamping rod 35 and the universal ball 37 from the clamping hole 16. At the same time, the convex ring 36 compresses the second spring 33. When the pulling force on the pull ring plate 34 is released, under the elastic action of the second spring 33, the clamping rod 35 is reset downward.

[0041] The rest of the structure is the same as that of Embodiment 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
