Description

Mold insert is with shape structure of preapring for an unfavorable turn of events among injection mold

Technical Field

The utility model relates to an injection mold spare part field specifically is an injection mold middle mold insert is with shape structure of preapring for an unfavorable turn of events.

Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. The method specifically comprises the steps of injecting heated and melted plastics into a mold cavity from an injection molding machine at high pressure, cooling and solidifying to obtain a formed product, wherein the temperature in the injection mold is uneven at each point and is related to the time point in the injection cycle. The function of the mold temperature controller is to keep the temperature constant between 2min and 2max, i.e. to prevent the temperature difference from fluctuating during the production process or across the gap. The following control methods are suitable for controlling the temperature of the die, and the control of the fluid temperature is the most common method, and the control precision can meet the requirements of most cases. With this control method, it is shown that the temperature at the controller and the mold temperature are not consistent; the temperature fluctuations of the mold are considerable because the thermal factors affecting the mold are not directly measured and compensated for, including changes in injection cycle, injection speed, melting temperature, and room temperature. The second is direct control of the mold temperature. The method is to install a temperature sensor in the die, and the method is adopted only under the condition that the requirement on the control precision of the die temperature is higher. The main characteristics of the mold temperature control include that the temperature set by the controller is consistent with the mold temperature; the thermal factors affecting the mold can be directly measured and compensated for, and the insert is very important within the mold cavity.

The existing insert is easy to deform, the injection molding effect is influenced, and the quality of the product is visualized, so that an insert deformation prevention structure is needed.
