Description

Technical Field

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

[0002] Battery pack insulators are devices used to isolate battery cells within a battery pack, preventing direct contact between the positive and negative electrodes and short circuits. They are typically designed to be inserted into the gaps between battery cells or between a battery cell and the battery pack casing to provide the necessary electrical insulation. Insulators in battery packs effectively isolate battery cells, preventing direct contact between them and thus avoiding short circuits. They also prevent direct contact between battery cells and the battery pack casing, further reducing the risk of short circuits. In addition to their insulating function, insulators also secure battery cells, preventing them from moving or loosening within the battery pack, thereby improving the pack's stability and safety.

[0003] Battery pack insulators are often produced using injection molding, primarily made from high-performance insulating materials such as polypropylene, polyimide, and polyamide. These materials have stringent temperature requirements during the molding process, requiring the injection mold temperature to be controlled within a certain range to ensure optimal performance of the resulting insulator.

[0004] The mold forming system for producing insulators includes an upper mold plate, a mold core, and a lower mold plate. In the existing mold, the temperature measurement and heating positions during the production process are mostly located outside the upper mold plate. This may cause the temperature measured by the upper mold plate to meet the injection molding requirements while the temperature of the mold core does not. The performance of insulators produced at this temperature cannot be guaranteed. Utility Model Content

The performance of the insulators produced at this temperature cannot be guaranteed.

[0006] The utility model provides the following technical solution: a mold with a temperature control structure, comprising an upper template, a first wire-burying groove is formed at the top of the upper template, a second wire-burying groove is formed on the side of the first wire-burying groove, a plurality of first mounting grooves are evenly formed on the first wire-burying groove, and a first closing cover is provided on the upper side of the first wire-burying groove;

[0009] Preferred technical solution 2: A side connecting frame is provided on the side of the upper template, and a constant temperature controller connector is provided on the side connecting frame.

[0010] Preferred technical solution three: the side opening of the first wire-burying groove extends to the side wall of the upper template, and the first wire-burying groove and the second wire-burying groove are connected.

[0011] This solution can better accommodate the wire harnesses arranged in the first wire burying trough and the second wire burying trough.

[0012] Preferred technical solution four: the end of the thermostat connector extends to the side opening of the first buried cable trough.

[0013] This solution can make it easier for the thermostat connected to the thermostat connector to be connected to the wiring harness arranged in the first and second wire burying troughs.

[0025] A heating rod mounting groove 15 is opened on the side of the bottom connecting groove 14, and two heating rod bodies 16 are inserted in the heating rod mounting groove 15. The top end of the heating rod body 16 passes through the middle through hole 10 and extends to the second buried wire groove 3. A thermocouple body 17 is provided on the side of the heating rod body 16, and the bottom end of the thermocouple body 17 is inserted into the thermocouple mounting groove 13. The top end of the thermocouple body 17 passes through the middle through hole 10 and extends to the second buried wire groove 3. A side connecting frame 18 is provided on the side of the upper template 1, and a constant temperature controller connector 19 is provided on the side connecting frame 18.

[0026] Embodiment 2: The difference between this embodiment and embodiment 1 is that the side opening of the first cable burying groove 2 extends to the side wall of the upper template 1, and the first cable burying groove 2 and the second cable burying groove 3 are connected.

[0027] The wire harnesses arranged in the first wire burying groove 2 and the second wire burying groove 3 can be better stored.

[0028] Embodiment 3: The difference between this embodiment and embodiment 1 is that the end of the constant temperature controller connector 19 extends to the side opening of the first buried cable groove 2.

[0029] This makes it easier for the thermostat connected to the thermostat connector 19 to be connected to the wiring harnesses arranged in the first buried wire trough 2 and the second buried wire trough 3 .

[0030] Embodiment 4: The difference between this embodiment and embodiment 1 is that a mounting hole is provided on the side of the side connecting frame 18 and a mounting hole is provided on the side of the upper template 1.

[0031] This makes it more convenient for users to install the side connecting frame 18 and the upper template 1.

[0032] In this embodiment, since the temperature measurement and heating positions of the existing mold during the production process are mostly located outside the upper mold plate, there will be a problem that the temperature measured by the upper mold plate has reached the injection molding requirements but the core temperature has not reached it. The performance of the insulator produced at this temperature cannot be guaranteed.

[0033] In summary, in the specific implementation, when the user needs to heat and measure the internal temperature of the molding core 12 inserted into the lower mold groove, the user first needs to insert the heating rod body 16 into the heating rod mounting groove 15 respectively, and the top of the heating rod body 16 passes through the middle through hole 10 and extends into the second buried wire groove 3, and the connecting wire harnesses will be arranged in advance in the first buried wire groove 2 and the second buried wire groove 3, so that the connecting wire harnesses can be regularly arranged in the first buried wire groove 2 and the second buried wire groove 3.

[0034] The end of the constant temperature controller connector 19 will be connected to an external constant temperature controller, and temperature measurement and temperature control will be performed through the constant temperature controller. The wiring harness arranged in the first buried wire groove 2 and the second buried wire groove 3 will be connected to the constant temperature controller through the constant temperature controller connector 19, and the heating of the heating rod body 16 will be controlled by the constant temperature controller. The top of the thermocouple body 17 inserted into the thermocouple mounting groove 13 also passes through the middle through hole 10 and extends to the second buried wire groove 3, and is connected to the wiring harness arranged in the second buried wire groove 3.

[0035] The end of the wiring harness is connected to the constant temperature control instrument through the constant temperature control instrument connector 19, and the temperature inside the molding core 12 measured by the thermocouple body 17 is transmitted to the constant temperature control instrument in real time, thereby facilitating subsequent users to control the overall temperature of the molding core 12, ensuring that the insulators produced on the molding core 12 have higher performance and are convenient for users' subsequent use.
