Abstract

The invention relates to the technical field of an injection molding machine, in particular to an electromagnetic mold locking injection molding machine. The electromagnetic mold locking injection molding machine comprises a machine frame, guide posts, a back seat and a movable plate and is characterized in that the four guide posts are arranged between the machine frame and the back seat; the movable plate movably sleeves on the guide post in a penetrating way; a walking trolley is arranged on the movable plate in a way of corresponding to the guide post so that the movable plate can move forwards and backwards along the guide posts; a fixed mold is arranged at one side, facing the movable plate, of the back seat; a movable mold is arranged at one side, facing the back seat, of the movable plate; a plurality of clamp grooves are respectively formed in the back seat and are positioned above and under of the screw bolts; the clamp grooves are connected with an electromagnet through clamp heads clamped into the clamp groove; the electromagnet is arranged at the front end of the back seat and is directly in contact with the movable plate; the locking capability is greatly improved; aplurality of clamp grooves are installed; the clamp grooves with the corresponding height can be selected for installing the electromagnet according to different molds; the transverse position of theelectromagnet in the clamp grooves can be selected according to the size of the molds.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an electromagnetic clamping injection molding machine. Background technique [0002] The mold of the injection molding machine is generally equipped with a movable mold and a fixed mold, and the two generally need to be locked during injection molding. In the prior art, toggle locks or hydraulic locks are generally used to lock the mold. The disadvantage of the above technical solution is that there is mechanical friction, which will inevitably lead to damage, slipping and other situations that affect the locking after long-term use. [0003] Improvements have been made in the industry, such as the electromagnetic clamping injection molding machine disclosed in the Chinese patent, application number 200610036130.6, which is characterized in that the electromagnet is installed on the back of the fixed mold, and when the movable mold is close to the fixed mold, ...
