Description

Injection molding machine mode locking mechanism Technical Field The utility model relates to the technical field of injection molding machines, in particular to a mold locking mechanism of an injection molding machine. Background Disposable articles, generally referred to as a type of low-cost, durable and disposable articles, are disposable plastic bags, snack boxes, paper cups, sanitary chopsticks, etc., and currently, for the production of disposable cutlery boxes and disposable cups, it is necessary to use an injection molding machine to make thermoplastic or thermosetting plastic into plastic products of various shapes using plastic molding dies. Through investigation, china patent utility model discloses an injection molding machine (publication number: CN 213291126U) for producing disposable cutlery boxes, which comprises a machine body, wherein a pushing device and an injection molding device are arranged in the machine body, a controller is arranged on one side surface wall of the machine body, a mounting plate is arranged at the top of the machine body, a through hole is formed in the surface wall of the mounting plate, a support is arranged at the top of the mounting plate, and one side, far away from the mounting plate, of one end of the support is rotationally connected with a driving wheel through a rotating shaft. In the above-mentioned patent, although compare with prior art, stir leaf turns over stir-fry in the inner tube back and forth through the drive of first motor, prevent that the material from sticking together and influencing the injection molding, the ventilation hole has been seted up to the inner tube surface wall that sets up simultaneously, the air inlet machine and the play fan that the cooperation urceolus surface wall set up, can strengthen the inside circulation of air of inner tube, prevent inside damp and hot influence injection molding quality, but the injection molding machine that is used for disposable cutlery box production among the prior art mostly does not normally possess the function of mode locking, result in the injection molding in-process, the raw materials can produce a power that props the mould when injecting into the die cavity with high pressure, so that the mould exists the risk of being strutted, thereby can cause the movable mould to take place elastic deformation and influence the quality of moulding plastics.
