Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a quick-changing device for replacing mold accessories. Background Art

[0002] The die casting mold needs to be replaced, but the mold replacement speed in the existing technology is slow. The reasons are:

[0003] Die casting molds are usually designed to be complex, and this complexity makes the mold disassembly and installation process cumbersome, requiring more time and manpower.

[0004] When replacing a mold, it is necessary to ensure that the new mold can be accurately positioned on the die casting machine. However, due to the complexity and weight of the mold, the positioning process becomes difficult and requires repeated adjustments and manual locking of the mold positioning mechanism, which increases the replacement time. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0006] To this end, one purpose of the present invention is to provide a quick-change device for replacing mold accessories to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a quick-change device for replacing mold parts, comprising a mold station and a bracket, wherein the front of the mold station is fixedly connected with a bracket, and the bracket is a bent structure;

[0008] A plurality of rollers are movably connected to the transverse part of the bracket, a hydraulic mechanism is installed on the front of the mold station, a plurality of hydraulic cylinders are arranged inside the mold station, and a plurality of slots are opened at the front edge of the inner side of the mold station;

[0009] A lock is movably connected to the inner side of the slot, and the lock is fixedly connected to the end of the corresponding hydraulic cylinder output end;

[0010] A card block is inserted into the card slot, and locking slots are provided on both sides of the card block, and the locking element is locked in the locking slots;

[0011] A bolt is fixedly connected to the top of the clamping block, a fastener is threadedly connected to the outer surface of the bolt, and a handle is fixedly connected to the top of the fastener.

[0012] Preferably, any of the above solutions has a bending angle of ninety degrees, and the top surface of the bracket is flush with the bottom surface of the inner side of the mold station.

[0013] Adopting the above technical solution: the core structure of the device is: a bracket, a roller, a hydraulic mechanism, a slot, a locking piece, a block, a locking slot, a bolt, a fastening rib and a handle.

[0014] This device is a quick-change device for mold accessories.

[0015] Preferably, any of the above schemes is that the back of the bracket is welded or riveted to the mold station, the roller is made of stainless steel, and the roller is arranged horizontally.

[0016] The above technical solution is adopted: when the device is implemented, the mold is placed flat on the roller of the bracket, and the mold is pushed toward the mold station along the roller. The design of the roller can effectively reduce the friction during the movement of the mold, thereby significantly reducing the thrust required for the mold to move, so that the mold can be quickly and easily pushed to the mold station;

[0017] After the mold is pushed into place, the block structure is inserted horizontally into the corresponding slot. At this time, the bolts of the block are threaded with fasteners, but they are not tightened. At this time, the hydraulic cylinder inside the mold station has not yet output. After the block is in place, the hydraulic cylinder outputs, the lock is pushed out, and it is stuck in the two lock slots of the block to lock the position of the block and the bolt. At this time, one side of the fastener is against the mold. By rotating the handle, the fastener can be tightened to position the mold against it, thereby realizing the rapid loading of mold accessories. When replacing mold accessories, you only need to loosen the fastener to make the lock retract. At this time, you can pull out the block and withdraw the mold along the bracket, so as to realize the rapid replacement of the mold.

[0018] Once the mold is pushed to the designated position, the mold can be quickly positioned and locked. This design avoids the tedious manual adjustment process and reduces the operation time. The positioning and locking process of the mold can be completed through simple clip-in and tightening operations, without the need for complex tools or professional skills, reducing the difficulty of operation and labor intensity. The output of the hydraulic cylinder and the locking mechanism of the lock ensure the stability and safety of the mold during the working process, reducing the risk of production accidents caused by mold displacement or loosening.

[0019] Preferably, according to any of the above schemes, the vertical cross-section of the slot is T-shaped, and the top and front of the slot are open.

[0020] Preferably, in any of the above schemes, the cross-sectional shape of the locking element is rectangular, and the shape of the locking element is matched with the shape of the locking slot.

[0021] Preferably, any of the above schemes is that the bottom surface of the fastener is screwed onto the bottom surface of the inner side of the mold station, and the fastener is formed by two cylinders connected up and down.

[0022] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0023] The quick-change device for replacing mold parts pushes the mold toward the mold station along the roller. The design of the roller can effectively reduce the friction during the movement of the mold, thereby significantly reducing the thrust required for the mold to move, so that the mold can be pushed to the mold station quickly and easily.

[0024] After the mold is pushed into place, the block structure is inserted horizontally into the corresponding slot. At this time, the bolts of the block are threaded with fasteners, but they are not tightened. At this time, the hydraulic cylinder inside the mold station has not yet output. After the block is in place, the hydraulic cylinder outputs, the lock is pushed out, and it is stuck in the two lock slots of the block to lock the position of the block and the bolt. At this time, one side of the fastener is against the mold. By rotating the handle, the fastener can be tightened to position the mold against it, thereby realizing the rapid loading of mold accessories. When replacing mold accessories, you only need to loosen the fastener to make the lock retract. At this time, you can pull out the block and withdraw the mold along the bracket, so as to realize the rapid replacement of the mold.

[0025] Once the mold is pushed to the designated position, the mold can be quickly positioned and locked. This design avoids the tedious manual adjustment process and reduces the operation time. The positioning and locking process of the mold can be completed through simple clip-in and tightening operations, without the need for complex tools or professional skills, reducing the difficulty of operation and labor intensity. The output of the hydraulic cylinder and the locking mechanism of the lock ensure the stability and safety of the mold during the working process, reducing the risk of production accidents caused by mold displacement or loosening.
