Description

Technical Field

[0001] The invention mainly relates to the technical field of thermoforming dies, and in particular to a punching machine for thermoforming dies. Background Art

[0002] Thermoforming mold processing is a new type of component forming process with high precision and high processing efficiency. Thermoforming mold processing is a processing method in which liquid components are directly punched into the mold and then quickly cooled to form the corresponding component shape. The hole processing of the thermoforming mold requires punching again after cooling and forming to achieve high dimensional precision.

[0003] At present, punching machines used for thermoforming mold processing often press down the punching shaft to punch the thermoformed parts. In this way, the waste chips formed by the punching are easily retained on the base, thereby affecting the subsequent punching work of the thermoformed parts. Summary of the invention

[0004] The present invention mainly provides a punching machine for thermoforming die processing to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A punching machine for hot forming mold processing, comprising a base, a plurality of top corners of the upper surface of the base are connected with top columns, the top ends of the plurality of top columns are connected to a support plate, a punching mechanism is connected to the plate body of the support plate, and a slag discharge mechanism is provided at the bottom end of the punching mechanism;

[0007] The punching mechanism includes an oil cylinder connected to the top of the plate body of the support plate, a lifting shaft connected to the output end of the oil cylinder, and a punching shaft and a plurality of telescopic shielding rods connected to the bottom end of the lifting shaft;

[0008] The slag discharge mechanism comprises a slag discharge hole arranged on the base, a slag discharge cavity communicated with the slag discharge hole, and a negative pressure component connected to the cavity body of the slag discharge cavity.

[0009] Furthermore, the telescopic shielding rod includes a guide inner shell inserted into the bottom end of the lifting shaft, and a sliding outer shell slidably connected to the outside of the guide inner shell. In the present invention, the telescopic shielding rod is extended and retracted by sliding the sliding outer shell on the guide inner shell, so that the telescopic shielding rod can fit the surface of the thermoformed component through the extension and retraction of the telescopic shielding rod, thereby effectively shielding the punching position.

[0010] Furthermore, a plurality of sockets for inserting telescopic shielding rods are provided at the bottom end of the lifting shaft, the inner wall of the hole body of the socket is connected to one end of the guide inner shell, a spring is provided in the hole body of the socket, one end of the spring abuts against the inner wall of the hole body of the socket, and the other end of the spring abuts against the outer surface of one end of the sliding outer shell. In the present invention, the lifting shaft accommodates the guide inner shell through the setting of the socket thereon, and the sliding outer shell is pushed to extend automatically through the setting of the spring.

[0011] Furthermore, a rubber ring is connected to the outer surface of one end of the guide inner shell extending to the inside of the sliding outer shell. In the present invention, when the telescopic shielding rod is extended, the volume for storing air in the sliding outer shell increases, so that the external gas pushes the rubber ring and enters the space for storing air in the sliding outer shell.

[0012] Furthermore, a spacer is connected to the inner bottom end of the sliding shell, a rubber cover is connected to the bottom end of the spacer body, and a gas supply hole is provided on the spacer body, and the gas supply holes are symmetrically arranged. In the present invention, the spacer is used to provide support for the rubber cover, so that the telescopic shielding rod is shortened to cause gas to pass through the gas supply hole and push the rubber cover open to enter the space at the bottom end of the spacer, and the gas entering the space is output through the exhaust hole at the bottom end of the sliding shell, thereby utilizing the gas blown toward the punching position to guide the discharge of waste chips.

[0013] Furthermore, a connecting column is connected to the top of the rubber cover, and the connecting column is inserted into the sheet body of the diaphragm. The connecting column is located between the two air delivery holes. In the present invention, the rubber cover is connected to the diaphragm by setting the connecting column.

[0014] Furthermore, an exhaust hole is provided at the bottom end of the sliding shell, and the hole body of the exhaust hole is arranged toward the lifting shaft.

[0015] Furthermore, connecting plates are connected to both sides of the lifting shaft, and an air pumping rod is connected to one end of the connecting plate away from the lifting shaft, and one end of the air pumping rod away from the connecting plate is connected to the upper surface of the base. In the present invention, the connecting plate is driven to move up and down by the lifting shaft, so that the air pumping rod connected thereto is driven to extend and retract by the connecting plate, so that air is pumped by the extension and retraction of the air pumping rod.

[0016] Furthermore, the connecting plate is a hollow structure, and the air outlet end of the pumping rod extends to the interior of the connecting plate. An air outlet hole is provided at the bottom of one end of the connecting plate close to the lifting shaft. In the present invention, the gas pumped out by the pumping rod enters the hollow connecting plate and is discharged through the air outlet hole on the connecting plate, so that the gas flows along the lifting shaft to dissipate the heat of the lifting shaft.

[0017] Furthermore, the negative pressure component includes a negative pressure fan connected to the outside of the base, and an air pipe connected to the air inlet end of the negative pressure fan, the air pipe is connected to the slag discharge chamber, and a filter is connected to the inner wall of the tube body at one end of the air pipe extending to the inside of the slag discharge chamber. In the present invention, the negative pressure fan is used to make the inside of the air pipe connected to it negative pressure, and the connection between the air pipe and the slag discharge chamber makes the inside of the slag discharge chamber negative pressure, so as to accelerate the falling of waste formed by punching.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Firstly, the present invention realizes the extension and retraction of the telescopic shielding rod by sliding the sliding outer shell on the guiding inner shell, so that the telescopic shielding rod can fit the surface of the thermoformed component through the extension and retraction of the telescopic shielding rod, thereby effectively shielding the punching position and preventing the splashing of waste chips.

[0020] Secondly, when the telescopic shielding rod of the present invention is extended, the volume for storing air in the sliding shell increases, so that the external gas pushes the rubber ring and enters the space for storing air in the sliding shell. The telescopic shielding rod is shortened, causing the gas to pass through the gas transmission hole and push the rubber cover open, and enter the space at the bottom end of the partition. The gas entering the space is output through the exhaust hole at the bottom end of the sliding shell, so that the gas blown toward the punching position is used to guide the waste chips into the slag discharge hole for collection.
