Description

Technical Field

[0001] This utility model relates to the field of silicone foam preparation technology, and in particular to a mold for preparing controllable density silicone foam material. Background Technology

[0002] According to Chinese Patent No. CN219191031U, a foaming mold for easy material handling includes a base, a frame fixedly mounted on the upper end of the base, symmetrically arranged on both sides of the frame, a mold assembly on the upper end of the base, located inside the frame, a top-ejector assembly at the lower end of the mold assembly, a demolding assembly at the lower end of the top-ejector assembly, and drive assemblies on both sides of the demolding assembly. The beneficial effects are: when the sliding block slides to the bottom of the half-groove, it stops sliding; the second sliding plate drives the connecting plate to move upward synchronously via a lead screw; when the gear moves to the height of the rack, the rack drives the gear to rotate, causing the worm to rotate, which in turn drives the worm wheel to rotate, causing the lead screw to rotate, reducing the distance between the connecting plate and the second sliding plate. This causes the second connecting block to drive the top-ejector plate to move upward relative to the movable plate, allowing the top-ejector plate to lift the foaming material, detaching the foaming material from the movable plate, preventing the foaming material from sticking to the top-ejector plate or the movable plate, and facilitating material unloading by workers.

[0003] The above-mentioned documents and existing technologies have the following technical problems: In the current mold technology for preparing silicone foam materials, it is difficult to ensure that the raw materials are fully and evenly mixed before foaming after pouring them into the lower mold, which leads to deviations in the density of the final product and uneven distribution and poor density consistency of the silicone raw materials in the mold. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mold for preparing controllable density silicone foam material.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold for preparing controllable density silicone foam material, comprising a base, a sleeve on the surface of the base, a vibration spring inside the sleeve, a lower mold at the top of the vibration spring, an electric heating wire inside the lower mold, a fixing plate on the surface of the base, a vibration assembly on the surface of the fixing plate, a connecting plate on the surface of the vibration assembly, sliding blocks on both sides of the connecting plate, a guide block on the surface of the base, and a guide groove on the side of the guide block.

[0006] Preferably, the vibration assembly includes a servo motor, a drive rod, a crank, a connecting rod, and a moving block. The output end of the servo motor is provided with a drive rod, the end of the drive rod is provided with a crank, the surfaces of the two cranks are provided with connecting rods, and the surfaces of the connecting rods are provided with moving blocks.

[0007] Preferably, the surface of the base is provided with a bracket, and a guide rod is provided between the bracket and the base.

[0008] Preferably, the bottom surface of the bracket is provided with a cylinder, the bottom surface of the cylinder is provided with a mounting plate, the bottom surface of the mounting plate is provided with an upper mold, and the guide rod is connected through the surface of the mounting plate.

[0009] Preferably, one end of the connecting rod is rotatably connected to the surface of the crank, and the other end of the connecting rod is rotatably connected to the surface of the moving block.

[0010] Preferably, the top surface of the movable block is connected to the bottom surface of the connecting plate, and the top surface of the connecting plate is connected to the bottom surface of the lower mold.

[0011] Preferably, the shape and position of the sliding block are adapted to the guide groove, and the sliding block is slidably connected to the guide block through the guide groove.

[0012] Beneficial effects

[0013] In this invention, a vibration assembly, a vibration spring, and a guide groove are employed. A servo motor drives a drive rod to rotate, and the crank at the end of the drive rod performs circular motion. The circular motion is converted into the vertical linear movement of the moving block via a connecting rod, which in turn causes the connecting plate to vibrate the lower mold vertically. Simultaneously, the vibration spring buffers the impact force generated by the vibration of the lower mold and assists the lower mold in achieving more stable and efficient vibration. This applies a continuous and regular force to the silicone raw material poured into the lower mold, promoting thorough mixing of the raw material within the lower mold. Furthermore, the sliding connection between the guide groove and the sliding block strictly limits the movement direction of the lower mold, ensuring that it can only perform stable vertical vibration and avoiding deviation or wobbling. This guarantees the stability of the mold closing process between the upper and lower molds. Through the coordinated work of these structures, the silicone raw material is fully and uniformly mixed before foaming, significantly improving the consistency of the final product density and thus significantly improving the overall quality of the silicone foam material.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4A mold for preparing controllable density silicone foam material includes a base 1, with a support 6 on the surface of the base 1. The base 1 serves as the basic support component of the entire mold, providing an installation platform for other components and ensuring structural stability. The support 6 is mainly used to support and fix other components. A guide rod 5 is provided between the support 6 and the base 1, guiding the vertical movement of the mounting plate 4 and ensuring the straightness and stability of the upper mold 3 during vertical movement, enabling the upper mold 3 to accurately close with the lower mold 2. A cylinder 16 is provided on the bottom surface of the support 6, serving as the power source for the vertical movement of the upper mold 3. Through the extension and retraction of the cylinder 16, the mounting plate 4 and the upper mold 3 mounted on its bottom surface are moved vertically, realizing the mold closing and opening operations with the lower mold 2. The mounting plate 4 is located on the bottom surface of the cylinder 16, and the upper mold 3 is located on the bottom surface of the mounting plate 4. The upper mold 3 cooperates with the lower mold 2, forming a closed space when the mold is closed. The silicone raw material foams and is formed within this space, determining the silicone... The upper surface shape and size of the silicone foam material are defined. The guide rod 5 is connected to the surface of the mounting plate 4. The surface of the base 1 is provided with a sleeve 14, which is used to accommodate the vibration spring 15, providing a stable installation space for the vibration spring 15 and also providing a certain degree of protection for the vibration spring 15. The vibration spring 15 is located inside the sleeve 14. The main function of the vibration spring 15 is to buffer the impact force generated when the lower mold 2 vibrates, extending the service life of the mold. At the same time, the vibration spring 15 can also assist the lower mold 2 to achieve more stable and efficient vibration, optimizing the vibration effect. The lower mold 2 is located at the top of the vibration spring 15. The lower mold 2 is the supporting component for the silicone raw material. The silicone raw material is placed inside. It cooperates with the upper mold 3 to jointly determine the final shape and size of the silicone foam material. The lower mold 2 is provided with an electric heating wire 13 inside. The electric heating wire 13 heats the silicone raw material inside the lower mold 2, causing the foaming agent in the silicone raw material to decompose, triggering a foaming reaction, and causing the silicone raw material to foam and form.

[0024] A fixing plate 8 is provided on the surface of the base 1. The fixing plate 8 is used to fix the vibration assembly 9, ensuring that the vibration assembly 9 is stable in position during operation and can function normally. The vibration assembly 9 includes a servo motor 901, a drive rod 902, a crank 903, a connecting rod 904, and a moving block 905. The output end of the servo motor 901 is provided with the drive rod 902, and the end of the drive rod 902 is provided with the crank 903. The surfaces of the two cranks 903 are provided with the connecting rod 904, and the surfaces of the connecting rod 904 are provided with the moving block 905. The movable block 905 has one end of the connecting rod 904 rotatably connected to the surface of the crank 903, and the other end of the connecting rod 904 rotatably connected to the surface of the movable block 905. The servo motor 901 serves as a power source, providing rotational power. Its output drives the drive rod 902 to rotate. The drive rod 902 connects the servo motor 901 and the crank 903, transmitting the rotational power of the servo motor 901 to the crank 903, causing the crank 903 to perform circular motion. This circular motion converts the rotational motion into the oscillation of the connecting rod 904, which in turn oscillates the crank 903. The circular motion of the handle 903 is converted into the vertical linear movement of the moving block 905. This vertical linear movement drives the connecting plate 10 and the lower mold 2 to vibrate vertically. The surface of the vibration assembly 9 is provided with the connecting plate 10. The top surface of the moving block 905 is connected to the bottom surface of the connecting plate 10, and the top surface of the connecting plate 10 is connected to the bottom surface of the lower mold 2. The connecting plate 10 connects the moving block 905 and the lower mold 2, transmitting the vertical linear motion of the moving block 905 to the lower mold 2, enabling the lower mold 2 to vibrate vertically in sync with the movement of the moving block 905. Sliding blocks 11 are provided on both sides of plate 10, and guide blocks 7 are provided on the surface of base 1. Guide grooves 12 are provided on the side of guide blocks 7. The shape and position of sliding blocks 11 are adapted to guide grooves 12. Sliding blocks 11 are slidably connected to guide blocks 7 through guide grooves 12. When the connecting plate 10 drives the lower mold 2 to vibrate, sliding blocks 11 slide along guide grooves 12, strictly limiting the movement direction of the lower mold 2, ensuring that the lower mold 2 can only make stable up and down vibrations, avoiding deviation or shaking, and ensuring the stability of the mold closing process of upper mold 3 and lower mold 2.

[0025] When using this controllable density silicone foam material to prepare the mold, the silicone raw material is first poured into the lower mold 2. The servo motor 901 is started, and the output end drives the drive rod 902 to rotate. The drive rod 902 causes the crank 903 at its end to move in a circular motion. This circular motion is converted into the vertical linear movement of the moving block 905 through the connecting rod 904. The moving block 905 drives the connecting plate 10, which in turn causes the lower mold 2 to vibrate up and down. During this process, the vibration spring 15 buffers the impact force and assists the lower mold 2 to vibrate smoothly and efficiently, allowing the raw material to be subjected to a continuous and regular force. The mixture is thoroughly mixed. At the same time, the sliding block 11 slides in the guide groove 12 to ensure that the lower mold 2 can only vibrate up and down stably. After the raw materials are mixed evenly, the electric heating wire 13 is activated to heat the raw materials in the lower mold 2, which promotes the decomposition of the foaming agent and triggers the foaming reaction. Then the servo motor 901 stops. At this time, the cylinder 16 works, and its extension and retraction action drives the mounting plate 4 and the upper mold 3 to move downward and close with the lower mold 2. The molding operation of silicone foam material is completed in the closed space. Throughout the process, the guide rod 5 ensures that the upper mold 3 moves smoothly and achieves precise mold closing. Specific Implementation Example 2:

[0027] A mold for preparing controllable density silicone foam material, based on the basic structure in Specific Embodiment 1, further discloses the following: In addition to the existing electric heating wire 13, a temperature sensor is embedded in the bottom of the lower mold 2. The temperature sensor can monitor the temperature inside the lower mold 2 in real time. The intelligent temperature control system automatically adjusts the power of the electric heating wire 13 according to the set temperature curve, so that the silicone raw material maintains a stable temperature during the foaming process and avoids product quality problems caused by temperature fluctuations.

[0028] In summary:

[0029] 1. The system employs a vibration assembly 9, a vibration spring 15, and a guide groove 12. A servo motor 901 drives a drive rod 902 to rotate, causing the crank 903 at the end of the drive rod 902 to rotate in a circular motion. The connecting rod 904 converts the circular motion into the vertical linear movement of the moving block 905, which in turn causes the connecting plate 10 to drive the lower mold 2 to vibrate up and down. Simultaneously, the vibration spring 15 buffers the impact force generated by the vibration of the lower mold 2 and assists the lower mold 2 to achieve more stable and efficient vibration. This applies a continuous and regular force to the silicone raw material poured into the lower mold 2, promoting thorough mixing of the raw material within the lower mold 2. Furthermore, the sliding connection between the guide groove 12 and the sliding block 11 strictly limits the movement direction of the lower mold 2, ensuring that it can only perform stable up and down vibrations, avoiding deviation or shaking, and ensuring the stability of the mold closing process of the upper mold 3 and the lower mold 2. Through the coordinated work of these structures, the silicone raw material is fully and uniformly mixed before foaming, significantly improving the consistency of the final product density and thus significantly improving the overall quality of the silicone foam material.
