Pneumatic ejection mold

Abstract

The invention belongs to the technical field of molds and particularly relates to a pneumatic ejection mold. The pneumatic ejection mold comprises a push plate, a supporting plate A, a sliding plate,a push table, a piston A, a base, a shell A, a loudspeaker, a spring B, a rotary rod, a clamping block B, a shell C and the like. The pneumatic ejection mold is provided with the pneumatic alarm loudspeaker, a conical plug, a telescopic rod and the spring B. When equipment has an exception, the conical plug is pushed open by air pressure, the pneumatic alarm loudspeaker can give an alarm, and people can find an equipment failure more easily and can distinguish alarm sounds even in a noise environment. According to the pneumatic ejection mold, the piston A is reset through negative pressure; through cooperation of a sliding block A and an L-shaped plate A, the piston A in a cylinder block can do reciprocating motion only through an air charging device but without an air extraction device. Accordingly, the cost is reduced. Through design of a push disk, the rotary rod, a thread ring and a rotary disk, the air pressure alarm threshold value can be adjusted according to the weights of different workpieces, and it is ensured that the pneumatic ejection mold cannot give an alarm when the workpieces are ejected. The pneumatic ejection mold is simple in structure and has the good using effect.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a pneumatic ejection mould. Background technique [0002] At present, in the field of mold technology for fluid pressure to push out finished products, the injection of raw materials, the molding and pushing of products generally use timers, controllers, and actuators to automatically control the entire production process. Therefore, in the production process, the operator only needs to put The raw materials can be injected into the mold body, and the rest of the production process is completed by automatic control equipment. However, during the production process, problems such as equipment damage, circuit failure, and mold aging will inevitably occur. However, the production process is completely automated. , It is difficult for the operator to detect the abnormality of the equipment during the production process. If the abnormal problem of the equipment is not resolved quickly,...

Problems solved by technology

But this patent has the following problems: First, there is mechanical noise in the production process, and it is not easy for the staff on duty to distinguish whether the sound of the steel ball colliding with the metal contact piece is regular or not, so it is difficult to To distinguish whether the equipment is working normally; second, the ejection of the formed workpiece is completed by an air extraction device, the arrangement of the air extraction device leads to a redundant structure, high cost, and complicated maintenance; third, through the collision between the steel ball and the metal contact piece There is still such a disadvantage in judging whether the equipment is normal by the interval of the sound emitted. Due to human hearing fatigue, the judgment of the interval is easy to be inaccurate, and it is likely to make it difficult to find equipment failures.
