Description

Technical Field

[0001] The utility model relates to the technical field of water tank processing, and more specifically to a mold for water tank processing. Background Art

[0002] At present, when processing the sink, most of them rely on molds. In the prior art, the Chinese patent announcement number CN219188366U discloses a front flow sink processing mold. The utility model can drive the movable plate to move downward by extending the piston rod end of the electric cylinder, and the movable plate drives the upper mold to move downward and complete the mold closing with the lower mold. During the mold closing process, the cutting knife of the trimming part of the upper mold and the cutting knife of the trimming part of the lower mold bite and shear to achieve the trimming of the front flow sink product; the cutting knife of the side trimming part of the upper mold and the cutting knife of the side trimming part of the lower mold bite and shear to achieve the side trimming of the front flow sink product; the punching column and the punching groove cooperate to achieve the punching of the front flow sink product; and the trimming, side trimming and punching operations of the front flow sink product are completed at the same time, without the need to equip special trimming, side trimming and punching processing molds respectively.

[0003] In the above-mentioned prior art, the trimming part is used to synchronously trim the edge of the sink, but the trimming part and the mold move synchronously. Under this structure, when the mold falls on the surface of the material, the trimming part also reaches the surface of the material synchronously. When the mold continues to fall, the trimming part also continues to fall. At this time, the mold has just begun to contact the material, and the deformation of the material has not been completely completed, but the bottom of the trimming part falls synchronously below the upper surface of the material, which will form an obstruction around the material, thereby easily causing material piling to form around the material (when the material is plastically deformed, it can only spread to other gaps due to the obstruction of the trimming part to form a burr edge). In summary, it still has certain defects in use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a mold for processing a water tank to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a water tank processing mold, comprising: an upper mold, a lower mold, a frame, a stamping assembly, and a trimming assembly, wherein the lower mold is fixedly installed at the bottom of the frame, the upper mold is located directly above the lower mold and is connected to the stamping assembly, and the stamping assembly is installed above the frame, and the upper mold is driven to move up and down by the stamping assembly, and the trimming assembly is installed around the upper mold and the lower mold, and the burr edge of the material is trimmed by the trimming assembly.

[0006] Furthermore, the stamping assembly includes a hydraulic cylinder, which is fixedly installed above the frame, and the movable end of the hydraulic cylinder is fixedly connected to the upper die.

[0007] Furthermore, the stamping assembly also includes a guide rod, which is slidably inserted on the frame, and the guide rod is parallel to the movable end of the hydraulic cylinder, and the bottom end of the guide rod is fixed to the upper die.

[0008] Furthermore, the trimming assembly includes a trimming frame and a trimming groove. The trimming frame is slidably mounted on the side of the upper mold, and the lower surface of the trimming frame is higher than the lower surface of the upper mold. The trimming groove is opened around the upper surface of the lower mold. The trimming frame is equipped with a lag assembly, which causes the trimming frame to lag behind the upper mold when falling.

[0009] Furthermore, the bottom surface of the trimming groove is an inclined structure, and the inner frame edge of the trimming frame overlaps with the outer frame edge of the trimming groove, and the trimming groove overlaps with the edge of the lower mold.

[0010] Furthermore, the lag assembly includes a lag rod and a connecting plate. One end of the lag rod is fixed to the upper surface of the upper mold, and the other end is slidably inserted in the movable end of the hydraulic cylinder. The connecting plate is fixedly installed on the movable end surface of the hydraulic cylinder. A connecting rod is fixedly installed on the lower surface of the connecting plate, and the end of the connecting rod away from the connecting plate is fixedly connected to the trimming frame.

[0011] Furthermore, a limit plate is slidably installed in the movable end of the hydraulic cylinder, and the limit plate is fixed to the hysteresis rod, and the diameter of the limit plate is greater than the diameter of the hysteresis rod.

[0015] 2. During use of the utility model, the buffer spring in the trimming assembly can also form a buffer between the upper die and the hydraulic cylinder to prevent the reaction force generated by the upper die from directly acting on the hydraulic cylinder, which will effectively reduce the wear of parts inside the hydraulic cylinder and thus extend its service life.

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The water tank processing mold involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] Reference Figure 1-4 The utility model provides a mold for sink processing, including: an upper mold 1, a lower mold 2, a frame 3, a stamping assembly, and a trimming assembly. The lower mold 2 is fixedly installed at the bottom of the frame 3, the upper mold 1 is directly above the lower mold 2, and is connected to the stamping assembly. At the same time, the stamping assembly is installed above the frame 3, and the upper mold 1 is driven up and down by the stamping assembly. The trimming assembly is installed around the upper mold 1 and the lower mold 2, and the burr edge of the material is trimmed by the trimming assembly.

[0023] The stamping assembly includes a hydraulic cylinder 4, which is fixedly mounted above the frame 3, and the movable end of the hydraulic cylinder 4 is fixedly connected to the upper die 1, so that the upper die 1 can be driven down to complete the stamping action by simply extending the movable end of the hydraulic cylinder 4.

[0024] The stamping assembly also includes a guide rod 13, which is slidably inserted on the frame 3 and parallel to the movable end of the hydraulic cylinder 4. At the same time, the bottom end of the guide rod 13 is fixed to the upper mold 1, so that the movement stability of the upper mold 1 can be greatly improved.

[0025] The trimming assembly includes a trimming frame 5 and a trimming groove 6. The trimming frame 5 is slidably mounted on the side of the upper mold 1, and the lower surface of the trimming frame 5 is higher than the lower surface of the upper mold 1. The trimming groove 6 is opened around the upper surface of the lower mold 2. The trimming frame 5 is equipped with a lag assembly, and the lag assembly is used to make the trimming frame 5 lag behind the upper mold 1 when falling. In this way, during the descent of the upper mold 1, the trimming frame 5 can be driven to move downward, and under the action of the lag assembly, it lags behind the lower mold 2 and closes with the trimming groove 6, thereby ensuring that the product is completely trimmed.

[0026] The bottom surface of the trimming groove 6 is an inclined structure, which is convenient for material cutting, and the inner frame edge of the trimming frame 5 overlaps with the outer frame edge of the trimming groove 6, and the trimming groove 6 overlaps with the edge of the lower mold 2, thereby facilitating the formation of shear force to trim the burrs of the material.

[0027] The hysteresis assembly includes a hysteresis rod 7 and a connecting plate 8. One end of the hysteresis rod 7 is fixed to the upper surface of the upper mold 1, and the other end is slidably inserted in the movable end of the hydraulic cylinder 4. The connecting plate 8 is fixedly installed on the movable end surface of the hydraulic cylinder 4, and a connecting rod 9 is fixedly installed on the lower surface of the connecting plate 8. The end of the connecting rod 9 away from the connecting plate 8 is fixedly connected to the trimming frame 5. In this way, when the upper mold 1 moves downward, it will first close the mold with the lower mold 2, and then the hysteresis rod 7 slides into the movable interior of the hydraulic cylinder 4, but the trimming frame 5 continues to move downward, so that a hysteresis action can be formed.

[0028] A limit plate 10 is slidably installed in the movable end of the hydraulic cylinder 4, and the limit plate 10 is fixed to the hysteresis rod 7. At the same time, the diameter of the limit plate 10 is larger than the diameter of the hysteresis rod 7, thereby preventing the hysteresis rod 7 from falling from the movable end of the hydraulic cylinder 4.

[0029] The movable end surface of the hydraulic cylinder 4 and the surface of the lag rod 7 are both fixedly mounted with mounting rings 11, and a buffer spring 12 is connected between the two mounting rings 11. At the same time, the buffer spring 12 is sleeved on the surface of the lag rod 7. The buffer spring 12 can effectively absorb the impact force generated when the upper die 1 is stamped, thereby protecting the hydraulic cylinder 4. At the same time, it can also give a pre-tightening force to the upper die 1, so that it can move synchronously with the movable end of the hydraulic cylinder 4.

[0030] Therefore, the complete usage process is to first place the steel plate of the raw material of the water tank on the lower die 2, and then drive the movable end of the hydraulic cylinder 4 to move downward to drive the upper die 1 to move downward. The downward movement of the upper die 1 will punch the material to form it according to the gap between the upper die 1 and the lower die 2, thereby making a water tank. After the upper die 1 overlaps with the lower die 2, the movable end of the hydraulic cylinder 4 will continue to extend. At this time, the upper die 1 will remain fixed, and the movable end of the hydraulic cylinder 4 will drive the trimming frame 5 to move downward through the connecting plate 8 and the connecting rod 9 until the trimming frame 5 overlaps with the trimming groove 6. During the overlapping process, a shear force will be formed at the overlapping surface of the trimming frame 5 and the trimming groove 6 to trim the burrs generated when the water tank is stamped. In this way, the entire processing process is completed.

[0031] In summary, when in use, the burrs of the sink after processing are trimmed through the trimming component. In comparison, it will not form an obstruction to the edge of the sink during the processing process, thereby ensuring stable trimming of the edge of the sink, and the function is more complete in use.

[0032] In addition, during use, the buffer spring 12 in the trimming assembly can also form a buffer between the upper mold 1 and the hydraulic cylinder 4 to prevent the reaction force generated by the upper mold 1 from directly acting on the hydraulic cylinder 4, which will effectively reduce the wear of parts inside the hydraulic cylinder 4 and thus extend its service life.
