Abstract
A pad printing carrier including a bucket mold and at least one breathing valve assembly. The bucket mold is used for holding a bucket-shaped workpiece and defines a cavity, an air inlet hole, at least one air outlet hole, and an airflow channel, the air inlet hole, the at least one air outlet hole, and the airflow channel are communicated with the cavity. The at least one breathing valve assembly is coupled with the at least one air outlet hole and each includes a counterweight unit, the weight of the counterweight unit is greater than the thrust generated by the air flow passing through the air outlet hole during demolding. A transmission device including the pad printing carrier is also provided.
Claims15
A pad printing carrier, comprising:
- a bucket mold (11), used for holding a bucket-shaped workpiece and defining a cavity (1111), an air inlet hole (1131), at least one air outlet hole (1121), and an airflow channel (1141);
- the air inlet hole (1131), the at least one air outlet hole (1121), and the airflow channel (1141) are communicated with the cavity (1111);
- and
- at least one breathing valve assembly (19), coupled with the at least one air outlet hole (1121) and each comprising a counterweight unit (12), the weight of the counterweight unit (12) is greater than the thrust generated by the air flow passing through the air outlet hole (1121) during demolding.
A pad printing carrier, comprising:
- a bucket mold (11), used for holding a bucket-shaped workpiece and defining:
- an air inlet hole (1131), facing the workpiece when the workpiece is loaded;
- a cavity (1111), communicated with air inlet hole (1131);
- at least one air outlet hole (1121), communicated with the cavity (1111);
- and
- an airflow channel (1141), through which the cavity (1111) communicating with an air pump (102);
- and
- at least one breathing valve assembly (19), coupled with the least one air outlet hole (1121) and each comprising:
- a breathing sheet (13), movably covering at least one of the at least one air outlet hole (1121);
- an elastic unit (15);
- and
- a counterweight unit (12), connected to the breathing sheet (13) through the elastic unit (15);
- wherein a pressure on the breathing sheet (13) generated by a weight of the counterweight unit (12) is greater than a thrust on the breathing sheet (13) generated by air in the cavity (1111) when the air pump (102) is inflating the cavity (1111) for demolding the workpiece.
