[0035] In one embodiment of the present invention, Figure 1-Figure 6 As shown, a shoe mold with temperature detection is provided, comprising an upper mold base 10 and a lower mold base 20. The upper mold base 10 is arranged at the top of the lower mold base 20, and the upper mold base 10 is provided with symmetrically distributed molding protrusions 11. Two groups of molding grooves 21 corresponding to the molding protrusions 11 are arranged in the lower mold base 20. A lifting mechanism 40 for ejecting the sole is connected in the molding groove 21. A detection mechanism is provided on one side of the molding groove 21.

[0036] The detection mechanism includes a heat conducting plate 31, a temperature sensor 32 and a digital display 33. The heat conducting plate 31 is arranged outside the molding groove 21, and is used to quickly transfer the temperature in the molding groove 21 to the temperature sensor 32. The temperature sensor 32 is arranged on the side of the heat conducting plate 31 away from the molding groove 21, and is used to detect the temperature in the molding groove 21. The digital display 33 is arranged on the lower mold base 20, and is electrically connected to the temperature sensor 32, and is used to display the temperature in the shoe mold.

[0037] When the upper mold base 10 and the lower mold base 20 are closed, the molding die transfers the temperature in the molding groove 21 to the temperature sensor 32 through the heat conduction plate 31 on one side. The temperature in the molding groove 21 is detected by the temperature sensor 32, and the detection signal is transmitted to the digital display 33. The real-time temperature is displayed by the digital display 33, which is convenient for the staff to timely understand the internal temperature in the shoe mold and make corresponding judgments and operations based on its internal temperature, so that the quality of the injection molded soles is better, the defective rate of the soles is reduced, and the production efficiency is improved.

[0038] Specifically, in another embodiment of the present invention, Figure 4-Figure 6 As shown, a limit plate 22 is provided on the outside of the temperature sensor 32, and a dustproof plate 23 is provided on the outside of the limit plate 22 to prevent dust from entering the lower mold base 20. A symmetrical installation cavity 201 is provided on the outside of the lower mold base 20, and the temperature sensor 32 and the limit plate 22 are sequentially arranged in the installation cavity 201 from the inside to the outside. The temperature sensor 32 is used to detect the temperature in the shoe mold, so that the staff can timely understand the temperature in the shoe mold and make judgments and operations according to the temperature value. A dustproof plate 23 is also provided to block dust, so as to prevent dust from entering the installation cavity 201 and affecting the detection effect of the temperature sensor 32.

[0039] The dustproof plate 23 is provided with a plurality of sets of fixing rods 231, and the dustproof plate 23 is provided outside the installation cavity 201, and the inner side of the dustproof plate 23 conflicts with the limiting plate 22. In this embodiment, there are four sets of fixing rods 231, and the fixing rods 231 are fixedly installed outside the installation cavity 201, so that the dustproof plate 23 can be securely installed, and the dustproof plate 23 is prevented from falling off the installation cavity 201 easily. At the same time, when the temperature sensor 32 is disassembled, the dustproof plate 23 can also prevent dust from entering the installation cavity 201.

[0040] Specifically, in another embodiment of the present invention, Figure 4As shown, the lifting mechanism 40 includes a lifting drive member 41, a connecting rod 42 and a push plate 43. The lifting drive member 41 is a cylinder, which is arranged in the lower mold base 20 and is located below the molding groove 21. The output end of the lifting drive member 41 is connected to the connecting rod 42, and the connecting rod 42 is connected to the push plate 43. The push plate 43 is slidably connected in the molding groove 21. When the lifting drive member 41 is started, the output end of the lifting drive member 41 drives the push plate 43 to lift up relative to the molding groove 21, and lifts up the sole in the molding groove 21, so that the staff can take out the sole from the shoe mold and simplify the sole removal steps.

[0041] A fixing plate 44 is provided on the connecting rod 42 for fixing. The fixing plate 44 is slidably connected to the lower die base 20. By providing the fixing plate 44, the connecting rod 42 can stably move up and down during the jacking process, avoiding excessive force on the push plate 43 during jacking to cause deformation of the connecting rod 42, thereby improving the service life of the connecting rod 42.

[0042] Specifically, in another embodiment of the present invention, Figure 2-Figure 3 As shown, a protrusion 111 is provided on the outer side of the molding protrusion 11. A mounting groove 211 corresponding to the protrusion 111 is provided on the top edge of the molding groove 21. When the upper mold base 10 and the lower mold base 20 are molded together, the protrusion 111 is tightly connected with the mounting groove 211. The coordinated use of the protrusion 111 and the mounting groove 211 plays a positioning role when the upper mold base 10 and the lower mold base 20 are molded together, preventing the upper mold base 10 and the lower mold base 20 from having a position deviation that affects the production quality of the sole. At the same time, the protrusion 111 is sealed and connected with the mounting groove 211, reducing the generation of flash during the molding of the sole and improving the production quality of the sole.

[0043] Specifically, in another embodiment of the present invention, Figure 1-Figure 2 As shown, the detection mechanism also includes several groups of signal lights 34. Several groups of signal lights 34 are arranged on the lower mold base 20 and located on one side of the digital display 33, and are used to display the working status of the shoe mold. In this embodiment, there are two groups of signal lights 34 with different colors, one group indicates that the shoe mold is in working state, and the other group indicates that the injection molding of the shoe mold has been completed. The staff can judge the working state of the shoe mold by the color of the signal lights 34, which is convenient for the staff to observe and improve the applicability of the shoe mold.

[0044] By setting up a detection mechanism, when the upper mold base 10 and the lower mold base 20 are closed, the molding die transmits the temperature in the molding groove 21 to the temperature sensor 32 through the heat conduction plate 31 on one side. The temperature in the molding groove 21 is detected by the temperature sensor 32, and the detection signal is transmitted to the digital display 33. The real-time temperature is displayed by the digital display 33, which is convenient for the staff to timely understand the internal temperature in the shoe mold and make corresponding judgments and operations according to its internal temperature, so that the quality of the injection molded sole is better, the defective rate of the sole is reduced, and the production efficiency is improved.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
