Constant temperature cooling device for daily chemical packaging injection mold

Abstract

The invention discloses a constant temperature cooling device for a daily chemical packaging injection mold. The device comprises a cooling water tower, a water tower steel platform, a cooling water tank, a cooling device and a detection device. The cooling water tower is installed above the water tower steel platform and used for cooling water completing primary cooling circulation. The cooling water tank is mounted at the bottom of the water tower steel platform and used for storing cooling water. The cooling device is mounted at the end, far away from the water tower steel platform, of the cooling water tower and is used for cooling water; The detection device is installed at the bottom of the cooling water tank and used for detecting the water temperature of the bottom of the cooling water tower, the water temperature can be detected by detecting the water density of the regional position through a buoyancy pipe,the detection precision is high, the detection range is large, and waste caused by the fact that cooling water meeting the requirement cannot directly flow out is avoided. Water delivery to the cooling water tank can be automatically stopped through a driving device when the water temperature in the cooling water tower is too high, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of plastic products, in particular to a constant temperature cooling device for daily chemical packaging injection molds. Background technique [0002] With the wide use of plastic products, the requirements for injection molding machines are also increasing. The temperature of the upper hopper of the injection molding machine will continue to rise with the increase of the working time of the injection molding machine, especially in the hot summer. The temperature of the upper hopper will rise faster. , and it is not easy to control, if the time is long, it is easy to cause the temperature of the raw material between the hopper mouth and the barrel inlet to rise, resulting in difficulty in feeding, and eventually leading to poor feeding. [0003] To sum up, in the process of production and processing, it is necessary to use the cooling system to cool the injection molding machine...

Problems solved by technology

[0002] Plastic products are widely used, and the requirements for injection molding machines are also increasing. The temperature of the hopper on the injection molding machine will continue to rise with the increase of the working time of the injection molding machine. Especially in the hot summer, the temperature rise rate of the upper hopper will be relatively fast, and it is not easy to control. If the time is long, the temperature of the raw material between the hopper mouth and the barrel inlet will easily rise, resulting in difficulty in unloading, and eventually lead to lower Unsatisfactory

[0003] In summary, the cooling system needs to be used to cool the injection molding machine at a constant temperature during the production process, but as the processing time increases during the cooling process, It often leads to insufficient cooling efficiency inside the cooling water tower, and then there is a situation where the temperature cannot be kept constant. When water needs to be replenished, it is impossible to measure the water at the water outlet of the cooling water tank in a large range. Only using a thermometer for detection can only detect the water temperature in one location. , the detection range is small, and it is easy to cause the cooling water that meets the requirements to be wasted because it cannot be used directly. Therefore, we propose a constant temperature cooling device for daily chemical packaging injection molds
