Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, for the utility model discloses an injection mold with temperature control's embodiment is shown the intention, and this injection mold includes mould 1, lower mould 2 and temperature control device 3, all be provided with runner 4 in going up mould 1 and lower mould 2, through set up the heat-conducting medium in runner 4, adjust the temperature of heat-conducting medium and flow back to last mould 1 and lower mould 2 by temperature control device 3 after exporting mould 1 and lower mould 2 with the heat-conducting medium to reach the purpose of control mold temperature. In this embodiment, in order to lead out the heat-conducting medium in the flow channel 4 of the upper die 1 and the lower die 2, the inlet and the outlet of the flow channel 4 are both connected with the quick connectors 5. In order to adjust the temperature of the flowing heat-conducting medium conveniently, the temperature control device 3 comprises a circulating pump 31, a spiral pipe 32 and a temperature control box 33. The heat-conducting medium in the pumping flow channel 4 of the circulating pump 31 is conveyed to the spiral pipe 32, the total length of the spiral pipe 32 is long, the heat-conducting medium can be fully heated or cooled in the spiral pipe 32, and then the heated or cooled heat-conducting medium flows back to the upper die 1 and the lower die 2 to preserve heat or cool the upper die 1 and the lower die 2. Specifically, circulating pump 31 one end is connected 4 export quick-operation joint 5 of runner, the circulating pump 31 other end is connected spiral pipe 32 one end, the spiral pipe 32 other end with the quick-operation joint 5 of 4 imports of runner links to each other. The circulating pump 31 is arranged at the outlet of the flow channel 4 so as to prevent the heat generated by the working of the circulating pump 31 from influencing the heat-conducting medium flowing through the circulating pump, the circulating pump 31 is arranged at the outlet of the flow channel 4, even if the heat of the circulating pump 31 influences the flowing heat-conducting medium, the temperature of the heat-conducting medium flowing out of the circulating pump 31 still needs to be adjusted through the spiral pipe 32, and the heat-conducting medium after the temperature of the heat-conducting medium is adjusted through the spiral pipe 32 flows into the upper die 1 and the lower die 2 again, so that the temperature of the heat-conducting medium. And the use of the circulating pump 31 enables the heat-conducting medium to be recycled, and the using amount of the heat-conducting medium is greatly reduced. The temperature of the heat transfer medium passing through the spiral tube 32 is adjusted because the spiral tube 32 is disposed in the temperature control box 33 through the bracket, and the temperature control range of the temperature control box 33 is wide, so that the spiral tube 32 can be heated, and the spiral tube 32 can be cooled at the same time. In this embodiment, the temperature control range of the temperature control box 33 is 0-100 ℃. To ensure rapid heat conduction of the coil 32, the coil 32 is an aluminum tube.
Referring to fig. 2, in order to improve the heat preservation or cooling efficiency of the upper die 1 and the lower die 2, a plurality of flow passages 4 are provided in the upper die 1 and the lower die 2, and the spiral pipe 32 and the circulating pump 31 are respectively connected with the plurality of flow passages 4 through the shunt pipes, so that the same temperature of the heat-conducting medium entering each flow passage 4 is ensured.
