The Influence of the Temperature of Plastic Injection Molds on the Product

1. The composition of plastic injection molds

Although the structure of the mold may vary widely due to the variety and performance of the plastic, the shape and structure of the plastic injection molds for sale, and the type of injection machine, the basic structure is the same. The injection mold is mainly composed of a gating system, a temperature regulation system, molding parts and structural parts. Among them, the gating system and the molding parts are the parts that are in direct contact with the plastic, and change with the plastic and the product. They are the most complex and changeable parts in the mold, and require the highest processing finish and precision.

The injection mold consists of a movable mold and a fixed mold. The movable mold is installed on the moving template of the plastic mould tooling machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a casting system and a cavity. When the plastic product factory opens the mold, the movable mold and the fixed mold are separated to take out the plastic products. In order to reduce the heavy workload of mold design and manufacturing, most of the plastic injection molds use standard mold bases.

2. The influence of the temperature of plastic injection molds on the products

Does the abs injection molding temperature of the plastic processing mold affect the product? In our usual production process, when some products are relatively small and the requirements are not very high, the cooling water is not connected, which seems to have little effect. For example: the mold kernel is cracked, and there is a waterway passing through the cracked place. There is really no way to repair it. It can only be produced without water, and some may not need to extend the cooling time. Some require longer cooling time, resulting in longer production cycle and lower production efficiency. However, in the case of high requirements for the product, after the water is connected, the fluctuation of the water temperature still plays a crucial role in the impact of the product. Not to mention no water.

If the appearance and size of the product are not very demanding, plastic injection mold makers generally use a low mold temperature to fill the plastic mold, which can shorten the cooling time and improve production efficiency. The mode of filling the mold with high mold temperature can make the product cool uniformly, prevent internal stress, cracking, etc. caused by excessive temperature difference, and can improve the flow marks, bonding lines and other undesirable conditions of the product.

In general, high injection mold temperatures need to be guaranteed by external equipment. Now there are more used on the market, such as mold temperature machine. Mold temperature machine can be divided into water type and oil type. The maximum working temperature of the standard water-type mold temperature machine is 120 ℃, and the maximum working temperature of the high-temperature water-type mold temperature machine is 180 ℃. Using the mold temperature machine, the mold can be brought to the set temperature and the mold temperature can be kept constant.
