Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically a temperature-measuring and heating plastic mold. Background Technology

[0002] Plastic molds are a general term for combination molds used in compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. Through the coordinated changes of the punch and die and auxiliary molding systems, plastic molds can produce a series of plastic parts of different shapes and sizes.

[0003] In the production process of plastic shoe soles, an appropriate amount of plastic raw material needs to be placed into the cavity mold. Then, the cavity mold is placed on the heating table and closed with the punch mold. Then, hydraulic cylinders and other devices are used to pressurize the punch mold, so that the plastic raw material is heated and formed in the mold cavity. Since the mold and the heating element in the heating table are indirectly in contact, the heating efficiency is low and it is not easy to control the temperature of the mold more precisely. At the same time, a lot of heat energy is lost. This needs to be improved. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a temperature-measuring and heating plastic mold includes a base frame 1. A lower mold base 11 is slidably installed inside the base frame 1. A plurality of columns 3 are fixedly connected to the outer wall of the base frame 1 via connecting seats 2. A top plate 4 is fixedly connected to the top of the plurality of columns 3. A hydraulic cylinder 5 is installed on the top plate 4. A flat plate 6 is fixedly connected to the push rod end of the hydraulic cylinder 5. An upper mold base 7 is fixedly installed at the bottom of the flat plate 6. An installation groove 15 is provided on the top surface of the lower mold base 11 and the bottom surface of the upper mold base 7. An upper mold 8 and a lower mold 12 are detachably installed in the two installation grooves 15 respectively. The bottom surface of the upper mold 8 is fixedly provided with a mold core 9. The top surface of the lower mold 12 is provided with a forming cavity 13 that is adapted to the mold core 9. The outer walls of the upper mold 8 and the lower mold 12 located in the mounting groove 15 are fixedly connected with an electric heating plate 19 and a temperature sensor 20. The outer walls of the upper mold base 7 and the lower mold base 11 are provided with a wire groove 21 that communicates with the mounting groove 15, so as to facilitate the wires of the electric heating plate 19 and the temperature sensor 20 to be passed out from the mounting groove 15. The outer walls of the upper mold 8 and the lower mold 12 located in the mounting groove 15 are covered with a heat insulation layer 22. The outer wall of the lower mold base 11 is fixedly installed with a handle 23.

[0021] By adopting the above-described scheme, in use, after placing an appropriate amount of plastic raw material into the molding cavity 13, the lower mold base 7 is pushed within the bottom frame 1 to align the lower mold 12 and the upper mold 8 vertically. Then, the hydraulic cylinder 5 is activated to push the platen 6 and the upper mold base 7 downwards, thereby closing the upper mold 8 and the lower mold 12 so that the mold core 9 can be inserted into the molding cavity 13. Afterwards, the electric heating plate 19 is activated to heat the upper mold 8 and the lower mold 12, thereby molding the plastic raw material within the molding cavity 13. Afterwards, the electric heating plate 19 is turned off, and the upper mold base 7 and the lower mold base 11 are reset, thus removing the molded plastic. The part is removed from the molding cavity 13, making the operation simple and convenient. Since the upper mold 8 and the lower mold 12 are directly heated by the electric heating plate 19, the heating efficiency is high. In addition, with the use of the temperature sensor 20, it is easy to monitor the temperature of the upper mold 8 and the lower mold 12, so as to make it easier to control the temperature of the upper mold 8 and the lower mold 12 more accurately. Through the setting of the heat insulation layer 22, the upper mold 8 and the lower mold 12 can be kept warm to reduce heat loss and prevent the temperature of the upper mold base 7 and the lower mold base 11 from getting too high, thereby reducing the chance of the operator being burned. The effect is good.
