[0026] Example 1:

[0027] like Figures 1 to 4 As shown, the utility model provides a packaging mold, comprising a box body 1 and a cover plate 2, wherein the cover plate 2 is arranged on top of the box body 1;

[0028] A cavity 11 for accommodating the inner core is formed downwardly on the top surface of the box body 1; an injection connector 3 and an exhaust connector 4 are connected to the side surface of the box body 1, and one end of the injection connector 3 and the exhaust connector 4 can be connected to the cavity 11, the other end of the injection connector 3 is connected to the injection equipment, and the other end of the exhaust connector 4 is connected to the vacuum generating equipment;

[0029] The injection device is used to inject packaging material into the cavity 11. In this embodiment, the packaging material is epoxy resin. In other embodiments, the packaging material may also be other resin materials or modified resin materials.

[0030] The vacuum generating device is used to extract the air in the cavity 11, so that the cavity 11 is in a state close to vacuum, so that the packaging material can fill the gap between the cavity 11 and the inner core, ensuring a better packaging effect; in this embodiment, the vacuum generating device can be a vacuum pump, and in other embodiments, the vacuum generating device can also be an exhaust fan, etc.

[0031] Among them, the injection connection part 3 needs to be set on the side of the box body 1 near the bottom, and the exhaust connection part 4 needs to be set on the side of the box body 1 near the top; the injection connection part 3 and the exhaust connection part 4 can be set on the same side or on different sides; in this embodiment, the injection connection part 3 is set on the left side of the box body 1 near the bottom, and the exhaust connection part 4 is set on the right side of the box body 1 near the top.

[0032] A plurality of connecting plates are provided on the outside of the box body 1 , and the connecting plates are respectively attached to one side of the box body 1 . At least some of the connecting plates are provided with a plurality of mounting cavities 5 , and the mounting cavities 5 can be used to install the heating structure 6 .

[0033] By installing the heating structure on the connecting plate attached to the box body 1, it is ensured that heat can be transferred to the cavity 11 in time, the curing effect of the packaging material in the cavity 11 is optimized, the curing speed of the packaging material is increased, the product is packaged efficiently, and a good yield is guaranteed.

[0034] Furthermore, it also includes a lifting mechanism 9, which is arranged below the box body 1; the lifting mechanism 9 includes a lifting rod 91, and a section of the lifting rod 91 extends into the mold cavity 11.

[0035] The lifting mechanism 9 is used to lift the product after packaging is completed to facilitate demoulding of the product.

[0036] Preferably, the cover plate 2 includes a main body 21 , a first positioning plate 22 and a second positioning plate 23 , and the first positioning plate 22 and the second positioning plate 23 constitute positioning holes 24 for positioning the inner core.

[0037] The positioning hole 24 formed by the cooperation of the first positioning plate 22 and the second positioning plate 23 limits the position of the inner core in the cavity 11, without the need for manual adjustment, thereby ensuring a better packaging effect and improving the packaging efficiency.

[0038] In another embodiment, at least five connecting plates are provided on the outside of the box body 1, namely a first mounting plate 71 provided above the box body 1, a second mounting plate 72 provided in front of the box body 1, a third mounting plate 73 provided behind the box body 1, a fourth mounting plate 74 provided on the left side of the box body 1 and a fifth mounting plate 75 provided on the right side of the box body 1; a plurality of mounting cavities 5 are provided on the first mounting plate 71, the second mounting plate 72, the third mounting plate 73, the fourth mounting plate 74 and the fifth mounting plate 75.

[0039] The top, front, back, left and right sides of the box body 1 are heated by the first mounting plate 71, the second mounting plate 72, the third mounting plate 73, the fourth mounting plate 74 and the fifth mounting plate 75 to ensure that heat can be transferred to the cavity 11 from five directions in a timely manner, optimize the curing effect of the packaging material in the cavity 11, increase the curing speed of the packaging material, efficiently package the product, and ensure a good yield rate.

[0040] Furthermore, at least a portion of the installation cavity 5 is used to install a heating structure 6 ; in this embodiment, a heating structure 6 is provided in each installation cavity 5 .

[0041] In this embodiment, the heating structure is a PTC heating element. In other embodiments, the heating structure may also be other structures that can generate heat.

[0042] All heating structures 6 are connected to the controller, and the temperature of the heating structure 6 is set by the controller to form a temperature gradient on the box body 1, which is convenient for controlling the curing sequence of the packaging material in the cavity 11, avoiding the occurrence of material shortages, flow marks, etc. that lead to unqualified products, and ensuring a better packaging effect.

[0043] Furthermore, a plurality of temperature sensors are provided on the box body 1 for measuring the temperature at different positions on the basic box body 1 , so as to facilitate the controller to control the heating structure 6 .

[0044] like Figure 5 As shown, in yet another embodiment, a sixth mounting plate 76 is provided below the box body 1 .

[0045] Furthermore, a plurality of mounting cavities 5 are formed on the sixth mounting plate 76. One of two adjacent mounting cavities 5 is used to mount the heating structure 6, and the other is used to mount the first thermal insulation structure 8.

[0046] The bottom and left and right sides of the box body 1 can also be heated to ensure that the packaging material at the bottom of the cavity 11 is solidified first, ensuring that the bottom of the product has a better packaging effect.

[0047] A lifting structure 9 needs to be installed at the bottom of the box 1, so a heating structure is generally not set at the bottom of the box 1. However, during the packaging process, material shortages are likely to occur at the bottom. After adding a sixth mounting plate 76 with a heating structure 6 to the bottom of the box 1, the material shortages at the bottom of the product after packaging are greatly reduced, resulting in a higher yield rate.
