Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1~Figure 4 As shown, this embodiment provides a hot press for processing automobile sound-absorbing cotton, comprising

[0027] An equipment rack, wherein a pair of movable holes are opened on the surface of the equipment rack, a movable column is connected to the movable sleeve in the movable hole, and a pressing mold is connected to the lower end of the movable column;

[0028] A driving assembly, the driving assembly being arranged outside the equipment rack and the movable column;

[0029] A switching component is arranged outside the equipment frame, and the switching component includes a pair of fixed plates, the fixed plates are fixed to the side surface of the equipment frame, the surface of the equipment frame is fixedly connected to a driving motor, the driving motor is fixedly connected to a transmission rod, the bottom of the equipment frame is fixedly connected to a base frame, the surface of the base frame is provided with an arc groove, a pair of track rods are fixedly connected in the arc groove, the outer sliding sleeve of the track rod is connected to a movable sleeve frame, the upper end surface of the movable sleeve frame is fixedly connected to a lower mold, and the lower mold is fixedly connected to one end of the transmission rod.

[0030] In this embodiment, in order to achieve the effect of intermittent switching of loading and unloading of the two lower molds, a switching component is designed. A base frame is fixedly connected to the bottom of the equipment frame, and an arc groove is opened on the surface of the base frame. A slide rod is arranged in the arc groove. The lower mold is slidably connected to the outside of the slide rod through a movable sleeve. Two slide rods and two movable sleeves are arranged, which are more stable when moving. Two driving motors are arranged at the center position of the equipment frame. The two driving motors are respectively connected to the lower molds on both sides through transmission rods at the output ends. The two driving motors are started separately, one rotates to the middle part of the base frame to wait for loading and unloading, and the other performs processing. Repeated switching can achieve the effect of uninterrupted processing, which can improve processing efficiency.

[0031] Specifically, in order to achieve the effect of intermittent pressing processing by the two pressing dies, a driving component is designed to drive the two upper dies, one of which is in a processing state and the other is in a waiting state.

[0032] Furthermore, the driving assembly includes a swing frame, which is rotatably connected to the side surface of the equipment frame, and grooves are provided on both opposite end surfaces of the swing frame. A connecting rod is rotatably connected to a pin shaft in the groove, and the lower end of the connecting rod is rotatably connected to the movable column through a pin shaft. A supporting frame is fixedly connected to the side surface of the equipment frame, and a groove is provided on the bottom surface of the swing frame. A hydraulic cylinder is rotatably connected to the groove and the swing frame through a pin shaft.

[0033] In this embodiment, the surface of the equipment frame is rotatably connected to a swing frame, and two hydraulic cylinders are rotatably connected to the support frame in the groove of the swing frame through a pin shaft. The two ends of the swing frame are rotatably connected to the movable column through a connecting rod. The two hydraulic cylinders will extend and retract respectively to drive the swing frame to swing to the left or right. On the downward tilted side, the movable column will move downward to press the pressing mold down to cooperate with the lower mold to complete hot pressing, and the pressing mold on the other side will be lifted, and loading and unloading can be carried out during this period.

[0034] Furthermore, the base frame is an overall semicircular structure.

[0035] In this embodiment, a semicircular structure is used to coordinate the movement stroke and angle of the lower mold, thereby reducing the occupied space of the equipment.

[0036] Furthermore, the pressing mold and the lower mold are located at the same axial position.

[0037] In this embodiment, the axis position is ensured so that misalignment does not occur when the pressing mold and the lower mold are replaced.

[0038] Furthermore, the maximum rotation angle of the lower mold with the output end shaft of the driving motor as the axis is 90°.

[0039] In this embodiment, the lower mold can be moved to the middle position of the base frame through a rotation angle of 90°, which facilitates loading and unloading operations.

[0040] Furthermore, the maximum rotation angle of the swing frame to both sides about the connecting axis is 45°.

[0041] In this embodiment, the maximum swing angle of 45° is used to ensure the descending depth of the movable column and the pressing mold at the lower end.

[0042] When processing is required, first drive one of the drive motors, slide the lower mold on the surface of the track rod to the middle position through the moving sleeve, put the material to be processed into the lower mold, and then reset it. After resetting, start the hydraulic cylinder, the hydraulic cylinder on the corresponding side contracts, and the other hydraulic cylinder extends, so that the corresponding pressing mold falls down for hot pressing. At the same time, the other drive motor is started to drive the lower mold on the other side to move to the middle position to load the material. After pressing is completed, switch, and then keep switching in a cycle to maintain an efficient processing speed.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
