[0002] A special device, carrier mould frame, is needed in sunroof hemming production. The mould needs to be placed on the carrier mould frame fixing plate. Since the mould is large in size and heavy in weight, manpower cannot complete the task, and external mechanism is usually needed to complete the task.

[0003] Most of the existing carrier mould frames use forklifts to change the mould. Since there is no buffering and sliding function, the carrier mould frame fixing plate and the mould are easily damaged, thereby damaging the equipment and the mould. Therefore, the utility model provides a quick die changing mechanism for carrier mould frame. UTILITY MODEL CONTENTS

[0005] Rollers are used to support the mould and reduce friction when sliding;

[0006] A main body is used to fix and install the rollers and the elastic sheets;

[0007] The elastic sheets are arranged below the rollers and are used to provide buffering and adjust the elastic force;

[0008] Screws are used to fix the elastic sheets and allow the shafts of the rollers to slide and be connected;

[0009] The shafts of the rollers are slidably connected to the screws at both ends, the elastic sheets are arranged below the shafts, and the shafts are pressed and compressed by the elastic sheets when the rollers are pressed downward by the mould.

[0010] Preferably, the elastic sheets are a multi-layer combined structure and are suitable for different mould weights.

[0011] Preferably, the sliding mechanism is symmetrically installed on the left and right sides of the carrier mould frame lower magnetic plate, thereby ensuring that the mould is uniformly stressed and preventing single-sided jamming.

[0012] Preferably, the sliding mechanism is embedded in the carrier mould frame lower magnetic plate, and the top of the roller is higher than the upper surface of the carrier mould frame lower magnetic plate, thereby avoiding hard contact between the mould and the magnetic plate and protecting the surface precision.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] When the mold is placed on the mold carrier, the lower plate of the mold directly presses on the rollers of the sliding mechanism, the rollers are sleeved on the screws through the sliding sleeves at both ends of the shaft, at this time the elastic sheets are in a natural state or a slightly compressed state, the weight of the mold presses down the rollers to compress and deform the lower elastic sheets, the elastic deformation of the elastic sheets absorbs impact energy, avoiding rigid collision between the mold and the lower magnetic plate of the mold carrier, the cumulative elastic force of the multiple elastic sheets increases with the increase of the compression amount, when the total elastic force of the elastic sheets is greater than the weight of the mold, the rollers are lifted by the elastic force, the lower plate of the mold is separated from the lower magnetic plate of the mold carrier, at this time the weight of the mold is completely supported by the rollers, and the mold can be horizontally slid by manpower, after the mold is moved out, the rollers are reset along the screws by the elastic sheets, and the next mold changing is prepared, the rollers are floating, when the lower plate of the mold presses on the rollers, the elastic sheets are compressed to prevent the mold from colliding with the rollers, when the mold gradually slides forward, more and more rollers support the mold, and the elastic force is greater than the weight of the mold, so that the mold is supported, and a gap is formed between the lower plate of the mold and the lower magnetic plate of the mold carrier, so that the mold can be slid forward, not only having a buffering effect, but also having a sliding effect, and the mold can be pushed and the position of the mold can be adjusted during mold changing.

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0020] By Figs. 1-2 It is given that the present application comprises a lower plate of mold 5 and a lower magnetic plate of mold carrier 6, a sliding mechanism 7 is arranged between the lower plate of mold 5 and the lower magnetic plate of mold carrier 6, and the sliding mechanism 7 comprises:

[0021] Roller 1, used to support the mold and reduce friction when sliding;

[0022] Main body 2, used to fix and install the roller 1 and the elastic sheet 3;

[0023] Elastic sheet 3, arranged below the roller 1, used to provide cushioning and adjust the elastic force;

[0024] Screw 4, used to fix the elastic sheet 3 and allow the shaft of the roller 1 to slide and fit;

[0025] The shaft of the roller 1 is slidably fitted at both ends on the screw 4, and the elastic sheet 3 is arranged below the shaft. When the roller 1 is pressed down by the mold, the shaft is lowered to press the elastic sheet 3.

[0026] The elastic sheet 3 is a multi-layer combined structure, suitable for different mold weights.

[0027] The sliding mechanism 7 is symmetrically installed on the left and right sides of the lower magnetic plate 6 of the mold carrier, ensuring that the mold is evenly stressed and preventing single-sided jamming.

[0028] The sliding mechanism 7 is embedded in the lower magnetic plate 6 of the mold carrier, and the top of the roller 1 is higher than the upper surface of the lower magnetic plate 6 of the mold carrier, avoiding hard contact between the mold and the magnetic plate and protecting the surface precision.

[0029] Working principle: When the mold is placed in the mold carrier, the lower plate 5 of the mold directly presses on the roller 1 of the sliding mechanism 7. The roller 1 is slidably fitted at both ends on the screw 4, and the elastic sheet 3 is in a natural state or slightly compressed state. The weight of the mold presses down the roller 1, and the roller shaft slides down along the screw 4 to compress and deform the elastic sheet 3 below. The elastic deformation of the elastic sheet 3 absorbs impact energy, avoiding rigid collision between the mold and the lower magnetic plate 6 of the mold carrier. The cumulative elastic force of the multi-layer elastic sheet 3 combination increases with the increase of the compression amount. When the total elastic force of the elastic sheet 3 is greater than the weight of the mold: the roller 1 is lifted by the elastic force, the lower plate 5 of the mold is separated from the lower magnetic plate 6 of the mold carrier, and a gap is generated. At this time, the weight of the mold is completely supported by the roller 1, and the mold can be pushed horizontally by human power. After the mold is moved out, the elastic sheet 3 rebounds, the roller 1 shaft slides up along the screw 4 to reset, preparing for the next mold change. When the roller 1 is pressed by the pressure of the lower plate 5 of the mold, it will press the elastic sheet 3 downward to prevent the mold from colliding with the roller 1. As the mold gradually slides forward, more and more support rollers are supported, and the elastic force will be greater than the weight of the mold, supporting the mold and creating a gap between the lower plate 5 of the mold and the lower magnetic plate 6 of the mold carrier. This allows the mold to be pushed and slid forward. Not only does it have a cushioning effect, but it also has a sliding effect, allowing the mold to be pushed and adjusted in position during mold changing.
