When the Molding Process Manufacturers push plate returns to the initial position, the switch on the mold operates..?Safety protection of injection molds in injection molding of plastic parts.In order to safely produce high quality and size qualified injection molded plastic parts, injection molds require special care during processing and storage as well as during production.

The safety device requires a receptacle provided on the movable mold fixing plate together with a switch provided on the mold. If the demolding part is placed behind the moving mold core or the slider, the push plate reset safety safety device is used to check whether the demolded part has returned to the initial position at the time of molding. Therefore, it is usually necessary to take measures to ensure that the mold is completely released and the mold part is reset before allowing the mold to close. At that time, the control system issued a command to 'close the mold.

However, the ejector plate reset safety device needs to change the mold structure. If this is not the case, then the molding cycle will be interrupted.' When the mold requires a long demolding stroke, the spring rest of the push plate is generally not very reliable. For a single cavity mold, it is sufficient to use a phototube for detecting whether the injection molded plastic part is dropped. When the mold is closed and the next cycle begins, the plastic parts retained in the mold will be damaged and such damage may further jeopardize the use of the mold. Only when the template light resetting device is applied during molding, that is, after the clamp is ejected, the mold clamping device is closed, and when the push plate is returned to the molding position by the spring force, the push plate reset safety device functions accordingly. To this end, a demolding reset mechanism is used to satisfy this function. This method cannot be used for multi-cavity molds
