Description

Technical Field

[0001] The utility model relates to the technical field of a die pressing device, in particular to a die pressing device for thermoforming. Background Art

[0002] Thermoforming is a plastic processing technology. The main principle is to heat and soften a flat plastic sheet, then use vacuum adsorption on the surface of the mold, and form after cooling. After thermoforming, die pressing is required, and a die pressing device for thermoforming is needed for workpieces

[0003] For example, a die pressing device for thermoforming with the authorization announcement number of "CN217226633U", through the transmission connection between the first sprocket and the second sprocket, the screw drives the supporting block to move downward through the threaded fit with the movable tube, so that the positioning strip disengages from the positioning hole, and there is enough spacing distance between the supporting block and the positioning pin. Then, the die is lifted upward. After the supporting block disengages from the corresponding mating groove, the die can be taken away. By reversing the operation, the installation of the die can be completed. The operation is simple and convenient. However, when disassembling the die pressing tool of this device, the die can only be disassembled after the screw drives the supporting block to move downward through the threaded fit with the movable tube, so that the positioning strip disengages from the positioning hole. The disassembly is relatively cumbersome, increasing the workload of the operator and reducing the working efficiency of this device. The cold air inhaled by the blower of this device is ejected downward from each air outlet to cool and lower the temperature of the formed plastic part. Due to the small cooling area, the cooling effect of this device is reduced. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the die can only be disassembled after the screw drives the supporting block to move downward through the threaded fit with the movable tube, so that the positioning strip disengages from the positioning hole, the disassembly is relatively cumbersome, increasing the workload of the operator and reducing the working efficiency of this device, and the cold air inhaled by the blower is ejected downward from each air outlet to cool and lower the temperature of the formed plastic part. Due to the small cooling area, the cooling effect of this device is reduced, and a die pressing device for thermoforming is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a die pressing device for thermoforming, including a box body and a frame. The upper end of the box body is fixedly connected with the frame. A cooling device is arranged on the left side of the frame. A hydraulic cylinder is fixedly connected to the inner wall of the frame.

[0012] A die pressing device for thermoforming proposed by the present utility model has the beneficial effects that: through the cooperation of the disassembly device and the mold, pulling the pull ring to move outward, the pull ring drives the insertion rod and the slide plate to move synchronously. While the slide plate moves, the spring is stretched. When the insertion rod no longer inserts into the through hole on the surface of the mold, the operator takes out the mold for replacement. After inserting the upper end of the new mold into the first outer shell and the upper end of the mold abuts against the upper inner wall of the first outer shell, the operator releases the pull ring.

The right end of the sliding rod 306 is fixedly connected to the air outlet box 8. When the sliding rod 306 moves, it drives the air outlet box 8 to move synchronously.

[0024] Refer to the appendix Figure 2 、 4 and Figure 5: The disassembly device 2 includes a first outer shell 201 and a fixing rod 202.

[0026] Working principle:

[0027] The process of disassembling and installing the mold 9:

[0028] When the mold 9 needs to be replaced, the operator pulls the pull ring 206 to move outward. The pull ring 206 drives the insertion rod 204 and the slide plate 203 to move synchronously. While the slide plate 203 moves, it stretches the spring 205. When the insertion rod 204 no longer plugs into the through hole on the surface of the mold 9, the operator removes the mold 9 for replacement. After inserting the upper end of the new mold 9 into the first housing 201, when the upper end of the mold 9 abuts tightly against the upper end inner wall of the first housing 201, the operator releases the pull ring 206. Under the reaction force of the spring 205, it drives the insertion rod 204 to move back to its original position. The insertion rod 204 passes through the through hole at the upper end of the mold 9 and abuts tightly against the groove at the left end inner wall of the first housing 201, completing the disassembly and installation process of the mold 9, making its disassembly and replacement more convenient.

[0029] The die pressing and cooling process of the workpiece:

[0030] The operator places the workpiece after blow molding on the surface of the support plate 6, and starts the telescopic end of the hydraulic cylinder 5 to extend, driving the mold 9 to move downward. After the mold 9 contacts the workpiece, die pressing operation is performed on it. The working principle during die pressing is the same as that in the patent with the authorized publication number "CN217226633U". After die pressing, control the telescopic end of the hydraulic cylinder 5 to shorten, driving the mold 9 to return to its original position. At the same time, connect the external power supply of the fan 7 and start the fan 7 to work. The air from the air outlet end of the fan 7 is discharged through the corrugated pipe and the air outlet box 8 to blow and cool the surface of the die-pressed workpiece. Connect the external power supply of the motor 301 and start the output shaft of the motor 301 to rotate, driving the turntable 303 to rotate synchronously. The turntable 303 drives the rotating rod 305 to rotate through the convex block 304. With the upper end of the rotating rod 305 as the rotation center, while the lower end of the rotating rod 305 moves, it drives the slide rod 306 to move. The movement of the slide rod 306 drives the air outlet box 8 to move synchronously. By driving the air outlet box 8 to move through the slide rod 306, the cooling area of the workpiece is increased, and the cooling effect is better, completing the die pressing and cooling process of the workpiece.
