Description

Technical Field

[0001] The utility model relates to the technical field of silicone molds, in particular to a silicone mold heating structure. Background Art

[0002] At present, silicone molds are one of the equipment used for the production and processing of electronic cigarette shells. The silicone molds are equipped with corresponding electronic cigarette mold cavities, which are fed into the silicone injection molding machine through a special mixing system, and injected into the heated liquid silicone mold by the injection molding machine at a certain pressure and speed. The silicone mold is heated by the heater to keep the mold at a corresponding temperature, which is convenient for silicone mixing and injection molding. The heater includes a control box, cables and heating tubes, which are distributed in the silicone mold to facilitate heating of the mold.

[0003] There are many existing technologies for the heating structure of silicone molds, such as:

[0004] Chinese patent publication number CN205021871U discloses a heating structure for silicone molds, which includes a heat-conducting copper plate, a heating rod, a thermocouple and a core template to form a quickly assembled and disassembled integrated structure. The heating rod and the thermocouple are hidden in a heat-conducting copper plate, separated from the core template to form a separate integrated heating structure template. The heat-conducting copper plate and the core template are fastened with screws. The structure is simple and easy to assemble and disassemble, ensuring its thermal conductivity, improving work efficiency and reducing manufacturing costs.

[0005] It can be seen that most silicone mold heating structures use heating rods and thermocouples for heating, but during use, uneven heating may occur. Over a long period of time, some heating rods may be damaged, which is not only inconvenient to replace, but also affects the heating effect of the silicone mold, reducing the flexibility of the heating structure, thereby reducing the practicality of the silicone mold heating structure.

[0006] In view of this, we propose a silicone mold heating structure. Utility Model Content

[0010] The upper installation box and the lower installation box are both provided with heating plates for dissipating heat to the silicone mold body, and the clamping assembly is used to assist the upper installation box and the lower installation box in clamping and installing the silicone mold body.

[0012] As a further improvement of the technical solution, a plurality of nano heating materials for improving heating efficiency and response speed are arranged inside the heating plate.

[0013] As a further improvement of the technical solution, the lower surface of the upper installation box and the upper surface of the lower installation box are both provided with anti-slip pads for increasing friction. The heating plate is honeycomb-shaped.

[0014] As a further improvement of this technical solution.

[0024] Most silicone mold heating structures use heating rods and thermocouples for heating, but during use, uneven heating may occur. Over a long period of time, some heating rods may be damaged, which is not only inconvenient to replace, but also affects the heating effect of the silicone mold, reducing the flexibility of the heating structure and thus reducing the practicality of the silicone mold heating structure.

[0025] See also Figure 1-Figure 3 The embodiment of the utility model shown in the figure comprises a silicone mold body 10 and an upper mounting box 11, both sides of the upper mounting box 11 are provided with clamping components 20, and one side of the clamping component 20 is provided with a lower mounting box 12; the interiors of the upper mounting box 11 and the lower mounting box 12 are provided with heating plates 13 for dissipating heat to the silicone mold body 10, and the clamping components 20 are used to assist the upper mounting box 11 and the lower mounting box 12 in clamping and mounting the silicone mold body 10.

[0026] First, the specific structure of the clamping assembly 20 is disclosed. The clamping assembly 20 at least includes a connecting box 21. Connecting boxes 21 are provided on both sides of the upper mounting box 11, and plug-in boxes 22 for plugging with the connecting box 21 are provided on both sides of the lower mounting box 12. A cylinder 23 is provided inside the connecting box 21, and a piston rod of the cylinder 23 is fixedly connected to the inner wall of the plug-in box 22.

[0027] The improvement lies in: connecting the cylinder 23 to a power source to make it work, and through the work of pushing the piston rod of the cylinder 23, the plug-in box 22 is moved away from the interior of the connecting box 21. At this time, the silicone mold body 10 can be placed inside the upper mounting box 11 and the lower mounting box 12, and through the work of resetting the piston rod of the cylinder 23, the upper mounting box 11 and the lower mounting box 12 are brought close to each other. At the same time, the silicone mold body 10 is clamped to complete the installation of the heating structure and the silicone mold body 10. It is not only simple to operate and improves the work efficiency of installation and disassembly, but also convenient for replacing the heating structure, thereby improving the flexibility of using the heating structure.

[0028] In order to improve the heating efficiency of the silicone mold, a plurality of nano heating materials 15 for improving the heating efficiency and response speed are arranged inside the heating plate 13 .

[0029] The improvement lies in that: by setting up the nano heating material 15, not only the heating efficiency and response speed are improved, but also the volume and weight are reduced. These nano heating materials 15 have a large surface area and excellent thermal conductivity, which improves the practicality of the heating structure, thereby improving the working efficiency of the silicone mold heating. The above-mentioned nano heating material 15 preferably uses metal nanoparticles, and carbon nanotubes can also be used.

[0030] When the upper mounting box 11 and the lower mounting box 12 clamp the silicone mold body 10, considering that the surface of the silicone mold body 10 may slip, which will affect the stability of the silicone mold body 10 in the fixed position, the lower surface of the upper mounting box 11 and the upper surface of the lower mounting box 12 are both provided with anti-slip pads 14 for increasing friction.

[0031] The improvement lies in that the anti-slip pad 14 is arranged to fit with the silicone mold body 10, thereby increasing the friction between the upper mounting box 11, the lower mounting box 12 and the silicone mold body 10, thereby preventing the silicone mold body 10 from being disengaged from the clamp and affecting the normal use of the heating plate 13. In severe cases, the silicone mold body 10 presses on the heating plate 13, causing damage to the heating plate 13, thereby improving the protection of the heating structure and thus increasing the service life of the heating structure.

[0032] In order to evenly distribute the heat inside the upper mounting box 11 and the lower mounting box 12 , the heating plate 13 is honeycomb-shaped.

[0033] The improvement lies in that the small holes of the honeycomb heating plate 13 can evenly distribute the heat inside the upper mounting box 11 and the lower mounting box 12, avoiding the occurrence of hot spots or cold spots, and making the silicone mold body 10 evenly heated, avoiding local overheating or low temperature problems. It not only improves the heat conduction efficiency and increases the heat conduction area, but also improves the energy utilization efficiency and saves energy consumption. It can also transfer heat to the silicone mold body 10 faster, achieving higher heating speed and efficiency, thereby improving the practicality of the heating structure.

[0034] In summary, the working principle of the present scheme is as follows: first, the cylinder 23 is powered on to make it work, and the plug-in box 22 is moved away from the interior of the connecting box 21 by the pushing work of the piston rod of the cylinder 23. At this time, the silicone mold body 10 can be placed inside the upper mounting box 11 and the lower mounting box 12, and the upper mounting box 11 and the lower mounting box 12 are brought close together by the resetting work of the piston rod of the cylinder 23. At the same time, the silicone mold body 10 is clamped, and then, the heating plate 13 is powered on to make it work. The heating work of the heating plate 13 can complete the heating of the silicone mold body 10.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model.
