DETAILED DESCRIPTION

[0021] The present application is further described below in combination with the accompanying drawings and examples, and the mode of the present application includes but is not limited to the following examples.

[0022] Example 1:

[0023] As Figures 1-5As shown, this utility model provides a plastic heat-sealing mold for processing automotive interior panels, comprising: an operating table 1, an upper template assembly 2 for mounting an upper mold and an installation cavity 3 for mounting a lower mold on the operating table 1, the upper template assembly 2 being able to rise and fall, the upper mold and the lower mold closing together to perform heat-sealing processing on the automotive interior panel, multiple adjustable heat dissipation plates 4 installed in the installation cavity 3, the top of the heat dissipation plates 4 being provided with a flexible heat-conducting layer, the flexible heat-conducting layer being thermally conductive silicone grease or a similar material, adjacent heat dissipation plates 4 being connected to a circulating water cooling device through a telescopic pipe 16, the circulating water cooling device providing circulating coolant to the heat dissipation plates 4 to dissipate heat to the parts of the lower mold that require heat dissipation, a support mechanism provided between the heat dissipation plates 4 and the installation cavity 3, the support mechanism including a frame 5 fixedly installed in the installation cavity 3, the heat dissipation plates 4 being located inside the frame 5, slide rails 6 being provided on both sides of the frame 5, sliders 7 being installed on the slide rails 6, a support plate 8 being installed at the bottom of the heat dissipation plates, the end of the support plate 8 being fixedly connected to the slider 7, two clamping plates 11 being installed in the slider 7, and a first clamping plate 11 being installed between the clamping plate 11 and the slider 7. Spring 12 and two clamping blocks 11 are respectively clamped at the top and bottom of slide rail 6, allowing slider 7 to move along slide rail 6, thereby adjusting the position of heat sink 4 laterally and achieving stillness through the first spring 12. In use, thermally conductive material (such as thermally conductive silicone grease) is evenly applied to the top of heat sink, and the lower mold is installed in the mounting cavity 3, so that the bottom of the lower mold is pressed against the top of heat sink 4. The thermally conductive silicone grease compensates for the influence of the part's machining accuracy, making the heat sink 4 and the lower mold as fully contacted as possible, thereby improving the heat conduction efficiency. Under the pressure of the lower mold, the support plate 8 is pressed down, thereby driving slider 7 to descend and further compressing the first spring 12 above slide rail 6 and extending the first spring 12 below slide rail 6. Through the extension and contraction of the first spring 12, the adverse effects of the part's machining accuracy and installation accuracy can be effectively compensated, so that the heat sink 4 can maintain as full contact as possible with the lower mold, which is conducive to improving the heat conduction efficiency between heat sink 4 and lower mold, improving heat dissipation efficiency, and allowing the parts of the plastic part that need heat dissipation to dissipate heat more quickly.

[0024] By setting up frame 5, slide rail 6, slider 7, support plate 8, clamping plate 11 and first spring 12, the heat sink 4 can be supported and the lateral position of the heat sink 4 can be easily adjusted. The extension and retraction characteristics of the first spring 12 can compensate for the adverse effects caused by the machining accuracy and installation accuracy of the parts, so that the heat sink 4 can fit better with the lower mold, and the plastic part can dissipate heat better.

[0025] Example 2:

[0026] like Figure 4 As shown, the top of the slider 7 is provided with anti-slip teeth 13. When in use, press the anti-slip teeth 13 on the top of the slider 7 and push it horizontally, so that the slider 7 can drive the clamping plate 11 to move horizontally through the first spring 12.

[0027] By setting anti-skid teeth 13 on the top of the sliding block 7, the anti-skid effect is achieved, and the sliding block 7 can be conveniently pushed to move.

[0028] Embodiment 3:

[0029] As shown in Figure 3 and Figure 5 , a back clamp 14 is installed at the bottom of the heat dissipation disc 4, the supporting plate 8 passes through the back clamp 4, a pressing plate 10 is arranged between the back clamp 4 and the supporting plate 8, a second spring 15 is installed between the pressing plate 10 and the back clamp 14, and the second spring 15 is compressed to make the pressing plate 10 extrude and fix the supporting plate 8 at the bottom of the heat dissipation disc 4, thereby fixing the heat dissipation disc 4. It is worth noting that the telescopic pipe 16 passes through the movable hole of the pressing plate 10, and in use, the two ends of the pressing plate 10 are pressed downward, so that the second spring 15 is further compressed, the pressure between the supporting plate 8 and the heat dissipation disc 4 is reduced, at this time, the heat dissipation disc 4 can be pushed to slide longitudinally on the supporting plate 8 until the heat dissipation disc 4 moves to the position where the lower mold needs to be enhanced to dissipate heat, and then the pressing plate 10 is released, and under the action of the second spring 15, the pressing plate 10 is raised and extruded to the supporting plate 8, so that the supporting plate 8 is connected and fixed with the heat dissipation disc 4.

[0030] By setting the pressing plate 10, the back clamp 14 and the second spring 15, the longitudinal position of the heat dissipation disc 4 can be conveniently adjusted.

[0031] Working principle: in use, the top of the heat dissipation disc is evenly coated with a heat-conducting material, the lower mold is installed in the installation cavity 3, the bottom of the lower mold is extruded on the top of the heat dissipation disc 4, the influence of part machining precision is compensated by the heat-conducting silicone grease, the heat dissipation disc 4 and the lower mold are in complete contact as much as possible, and the heat conduction efficiency is improved, under the pressure of the lower mold, the supporting plate 8 is pressed downward, thereby driving the sliding block 7 to descend, and the first spring 12 above the sliding rail 6 is further compressed, and the first spring 12 below the sliding rail 6 is elongated, through the extension and contraction of the first spring 12, the adverse effects of part machining precision and installation precision can be effectively compensated, the heat dissipation disc 4 can be kept in complete contact with the lower mold as much as possible, which is conducive to improving the heat conduction efficiency between the heat dissipation disc 4 and the lower mold, improving the heat dissipation efficiency, and enabling the parts needing heat dissipation to dissipate heat faster.
