Description

Technical Field

[0001] The utility model belongs to the technical field of helmet processing, in particular to a thermoplastic plastic helmet mould. Background Art

[0002] During the production process of thermoplastic plastic, the mold body is first heated through a heating pipeline to make the raw materials in the mold in a molten state, and then the mold is cooled through a cooling inner pipeline to solidify the molten thermoplastic plastic. The thermoplastic plastic helmet mold currently used includes a mold body with a cooling inner pipeline and a heating pipeline, and a cooling outer pipeline located outside the mold body. The cooling inner pipeline is connected to the cooling outer pipeline to form a closed cooling circuit, and a cooling water tower is arranged on the cooling outer pipeline. The hot water heated in the cooling inner pipeline is cooled by the cooling outer pipeline and the cooling tower and then enters the cooling inner pipeline of the mold body again to cool the mold body. In order to reduce energy consumption, the cooling outer pipeline adopts a natural cooling method, and the cooling outer pipeline is placed in a cool place. In the cold winter, the water in the cooling outer pipeline cools down very quickly, and the temperature of the water entering the cooling inner pipeline from the cooling outer pipeline is low. The mold body cools down quickly, the cooling time is short, the helmet quality is good, and the production efficiency is high. In spring and autumn, the temperature difference between day and night is large, the temperature at night is low, and the cooling effect basically meets the needs; but in the hot summer or during the daytime in spring and autumn, the temperature is relatively high, which causes the water in the cooling outer pipeline to cool down slowly, the water inlet temperature in the cooling inner pipeline is high, the mold body cools down slowly, the cooling time is long, the helmet quality is poor, and the production efficiency is low. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a thermoplastic plastic helmet mold which has high production efficiency, good product quality, energy saving and convenient use.

[0004] In order to solve the above problems, the technical solution adopted by the thermoplastic plastic helmet mold of the utility model is: it includes a mold body with a cooling inner pipeline and a heating pipeline, and a cooling outer pipeline located outside the mold body, the cooling inner pipeline is connected with the cooling outer pipeline to form a closed cooling circuit, a cooling water tower is arranged on the cooling outer pipeline, a cooling tank is connected in parallel on the cooling outer pipeline on the water inlet side of the cooling inner pipeline, a first regulating valve is arranged on the cooling tank, and a second regulating valve is arranged on the cooling outer pipeline in parallel with the cooling tank.

[0005] Its additional technical features are:

[0006] A temperature control probe is provided at the water inlet end of the cooling tank, and the temperature control probe is connected to the refrigeration variable frequency compressor of the cooling tank through a control mechanism;

[0007] A water-dividing tee is arranged at the place where the cooling external pipeline is connected in parallel with the cooling tank, and a bimetallic strip is arranged in the water-dividing tee.

[0008] Compared with the prior art, the thermoplastic plastic helmet mold provided by the utility model has the following advantages: first, since it includes a mold body with a cooling inner pipeline and a heating pipeline, and a cooling outer pipeline located outside the mold body, the cooling inner pipeline is connected with the cooling outer pipeline to form a closed cooling circuit, a cooling water tower is arranged on the cooling outer pipeline, a cooling tank is connected in parallel on the cooling outer pipeline at the water inlet side of the cooling inner pipeline, a first regulating valve is arranged on the cooling tank, and a second regulating valve is arranged on the cooling outer pipeline in parallel with the cooling tank. In cold winter, the second regulating valve is opened and the first regulating valve is closed, and the hot water heated in the cooling inner pipeline is cooled by the cooling outer pipeline and the cooling tower and then directly enters the cooling inner pipeline of the mold body again. Since the outside temperature is relatively low, the product quality is high; in hot summer and during the daytime in spring and autumn, the temperature is relatively high, the first regulating valve is opened and the second regulating valve is closed, and the hot water heated in the cooling inner pipeline is cooled by the cooling outer pipeline and the cooling tower and then enters the cooling inner pipeline of the mold body after passing through the cooling tank. In the pipeline, the cooling tank adopts the principle of a refrigerator. Water passes through the cooling tank for heat exchange, and the temperature is further reduced. In the nights of spring and autumn, although the temperature is low, the cooled water cannot meet the cooling needs of the mold body. The first regulating valve and the second regulating valve are opened at the same time, and a part of the water is cooled through the cooling tank, and then mixed with the water in the cooling outer pipeline and enters the cooling inner pipeline to cool the mold. The product quality is high, the production efficiency is high, and the energy-saving effect is good; secondly, since a temperature control probe is provided at the water inlet end of the cooling tank, and the temperature control probe is connected to the refrigeration variable frequency compressor of the cooling tank through a control mechanism, the power of the refrigeration variable frequency compressor of the cooling tank can be controlled according to the water temperature at the water inlet end of the cooling tank, and the temperature in the cooling tank can be adjusted in a targeted manner, and the energy-saving effect is better; thirdly, since a water-dividing tee is provided at the parallel connection between the cooling outer pipeline and the cooling tank, and a bimetallic strip is provided in the water-dividing tee, the first regulating valve and the second regulating valve are opened at the same time, and the bimetallic strip is bent to one side according to the temperature of the water flowing through, and the amount of water entering the cooling tank is adjusted, which is more convenient to use.

[0013] like Figure 1 and Figure 2 As shown, a schematic structural diagram of a thermoplastic plastic helmet mold of the utility model, the thermoplastic plastic helmet mold of the utility model comprises a mold body 3 with a cooling inner pipeline 1 and a heating pipeline 2, and a cooling outer pipeline 4 located outside the mold body 3, the cooling inner pipeline 1 is connected with the cooling outer pipeline 4 to form a closed cooling circuit, a cooling water tower 5 is arranged on the cooling outer pipeline 4, a cooling tank 6 is connected in parallel to the cooling outer pipeline 4 on the water inlet side of the cooling inner pipeline 4, a first regulating valve 7 is arranged on the cooling tank 6, and a second regulating valve 9 is arranged on the cooling outer pipeline 8 connected in parallel with the cooling tank 6.

[0014] In the cold winter, the second regulating valve 9 is opened and the first regulating valve 7 is closed. The hot water heated in the cooling inner pipeline 1 is cooled by the cooling outer pipeline 4 and the cooling tower 5, and then directly enters the cooling inner pipeline 1 of the mold body again.

[0015] A temperature control probe 10 is provided at the water inlet end of the cooling tank 6.
