[0025] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model will be described in detail as follows in combination with the drawings and preferred embodiments.
[0026] Please refer to Figures 1-6 The embodiment aims to provide a high-efficiency heat-insulating shunt plate pad, which comprises a heat-conducting layer 1, the bottom of the heat-conducting layer 1 is provided with a thermal insulation layer 2 through clamping, the bottom of the thermal insulation layer 2 is provided with a bottom layer 3 through clamping, and a sealing ring 4 is fixedly arranged on the outer wall of the shunt plate pad, the thermal insulation layer 2 comprises a first thermal insulation layer 21 connected with the heat-conducting layer 1, the other side of the first thermal insulation layer 21 is fixedly connected with an interlayer 22, and the other side of the interlayer 22 is fixedly connected with a second thermal insulation layer 23 connected with the bottom layer 3.
[0027] The shunt plate pad mainly insulates the heat in the hot runner system, the bottom layer 3 of the shunt plate pad directly contacts with the mold base of the hot runner system, the heat-conducting layer 1 directly contacts with the shunt plate, and the thermal insulation layer 2 is located between the bottom layer 3 and the heat-conducting layer 1, and the main purpose is to reduce or block the heat transfer between the mold and the shunt plate.
[0028] The interlayer 22 is fixedly provided with a bubble structure 221, the bubble structure 221 is filled with inert gas, has an extremely low thermal conductivity, such as argon, krypton or helium, and the like, the inert gas has an extremely low thermal conductivity, which means that it hardly transfers heat, so that the heat transfer in the thermal insulation layer 2 can be effectively blocked, and the bubble structure 221 makes the heat have to bypass the bubbles when passing through the thermal insulation layer 2, thereby greatly increasing the path length and difficulty of heat transfer, not only improving the heat insulation efficiency, but also enabling the thermal insulation layer 2 to have excellent heat insulation performance while maintaining lightness and thinness
[0029] The first thermal insulation layer 21 adopts aerogel material, which can further reduce the heat transfer rate from the bottom layer 3 to the heat-conducting layer 1, improve the heat insulation effect of the whole pad, and the second thermal insulation layer 23 adopts foam ceramic material, which can further enhance the heat insulation performance of the thermal insulation layer 2, and ensure that the heat is effectively isolated in the thermal insulation layer 2.
[0030] The upper surface of the heat-conducting layer 1 is wavy, which can significantly reduce the contact area with the flow distribution plate, and can more effectively reduce the heat transfer. The lower end of the heat-conducting layer 1 and the upper end of the bottom layer 3 are both provided with two symmetrically arranged clamping grooves 12.
[0031] The upper end of the first heat insulation layer 21 and the lower end of the second heat insulation layer 23 are both symmetrically provided with two clamping blocks 24, which are clamped in the clamping grooves 12. The clamping blocks 24 on the first heat insulation layer 21 are clamped in the clamping grooves 12 on the heat-conducting layer 1, and the clamping blocks 24 on the second heat insulation layer 23 are clamped in the clamping grooves 12 on the bottom layer 3. The outer wall of the clamping block 24 is fixedly connected with symmetric limiting protrusions 241. The limiting protrusions 241 are made of elastic materials such as rubber, silicone or thermoplastic elastomer, which have certain flexibility and recovery. When the clamping block 24 is clamped into the clamping groove 12, the limiting protrusion 241 will be extruded and deformed, but will quickly recover to the original shape, thereby tightly fitting on the side wall of the clamping groove 12. Not only does it increase the friction between the clamping block 24 and the clamping groove 12, preventing the heat insulation layer 2 from moving vertically, but also improves the sealing of the connection, preventing heat from leaking from the connection gap. This detachable structure further improves the installation convenience and replacement efficiency.
[0032] The lower surface of the bottom layer 3 is provided with a hexagonal honeycomb-shaped recess 31, which increases the path length and complexity of heat transfer, thereby improving the thermal resistance. Although the hexagonal honeycomb structure increases the thermal resistance, it also promotes the uniform distribution of heat to some extent, which helps to transfer heat to the mold base more quickly, thereby improving the heat conduction efficiency. However, it should be noted that this effect of promoting heat conduction is achieved while maintaining the overall heat insulation performance.
[0033] Two screw holes 11 are symmetrically provided through the flow distribution plate pad, and the screw holes 11 pass through the heat-conducting layer 1, the heat insulation layer 2 and the bottom layer 3. Screws 5 are screwed into the screw holes 11, which further enhances the connection strength between the heat-conducting layer 1, the heat insulation layer 2 and the bottom layer 3.
[0034] The sealing ring 4 is tightly installed on the side wall of the pad, forming an effective barrier that can prevent molten plastic from leaking from the side wall of the pad during the injection molding process. At the same time, the sealing ring 4 also plays a role in heat insulation, reducing the possibility of heat transfer from the side wall of the pad. In order to further enhance the heat insulation effect of the flow distribution plate pad, a flow channel 41 is fixedly arranged in the sealing ring 4. The flow channel 41 is spiral-shaped, and is used for further heat insulation. The flow channel 41 is filled with low-thermal-conductivity solid material.
[0035] The utility model discloses in specific use, the clamping block 24 on first heat insulation layer 21 is clamped in the clamping groove 12 on the heat conduction layer 1, and the clamping block 24 on second heat insulation layer 23 is clamped in the clamping groove 12 on the bottom layer 3, thereby preliminarily fixed the overall structure of the flow guide plate cushion block, then the screw 5 is screwed in the screw hole 11 and is screwed down to further fixed, then installs the sealing ring 4 in the cushion block outer wall, prevents molten plastic leakage and heat transfer, finally places the shunt plate cushion block on the mould base, ensures that the heat conduction layer 1 corresponds with the shunt plate, and the bottom layer 3 is closely contacted with the mould base.
[0036] The above is only the preferred embodiment of the utility model, and does not limit the utility model in any form, although the utility model has disclosed as above with the preferred embodiment, however, is not used to limit the utility model, any person skilled in the art, in the range of the utility model technical scheme, when can utilize the above-mentioned disclosed technical content to make a little more change or modification for equivalent embodiment of equivalent change, but as long as not departing from the utility model technical scheme content, according to the technical essence of the utility model to the above embodiment of any brief introduction modification, equivalent change and modification, still belong to the range of the utility model technical scheme.
