Description

Technical Field

[0001] This utility model relates to the field of mold demolding technology, specifically to a demolding device for mold processing. Background Technology

[0002] A mold is a tool used to mold, shape, or stamp materials. It is usually made of metal, plastic, or other materials. Mold processing is widely used in the automotive, electronics, construction, aerospace, and other fields and is an indispensable part of the manufacturing industry. After a product is molded by a mold, it needs to be removed by demolding. It is difficult to achieve automatic demolding. The molded part needs to be removed from the mold manually before the next workpiece can be injection molded. This method is time-consuming, labor-intensive, and has its drawbacks.

[0003] Existing technologies, such as the utility model disclosed in patent publication number CN222156367U, disclose a mold processing equipment for easy demolding, including a base, a mold collection plate, and a demolding assembly. An L-shaped mounting plate is fixedly connected to the outside of the base, and a hydraulic cylinder is fixedly connected to the top outer wall of the L-shaped mounting plate. The output end of the hydraulic cylinder passes through the side wall of the L-shaped mounting plate and is fixedly connected to an upper mold base. Two rows of circular grooves are formed on the upper surface of the base, with two grooves in each row. Damping rods are fixedly connected to the bottom inner wall of the circular grooves, and a placement plate is fixedly connected to the top of the four damping rods. A through groove is formed on the surface of the placement plate. Compared with the prior art, this application can realize automatic demolding of mold parts, which is convenient and fast, saving time and labor costs.

[0004] When processing thinner mold parts, the placement plate pushes the edge of the mold part after it has been formed, which can easily cause uneven stress on the mold part, leading to deformation and a decrease in the quality of the mold part.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a mold release device for mold processing that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a mold release device for mold processing, comprising: a frame, a lower mold, and a mold release mechanism for facilitating the removal of thinner mold parts;

[0008] The demolding mechanism includes a first steel wire rope and a second steel wire rope, which are respectively connected to the upper and lower sides of both ends of the mounting plate. Insert rods are evenly installed on the mounting plate. The mounting plate is aligned with the fixing plate. The lower mold is fixedly installed on the fixing plate.

[0009] Furthermore, the fixing plate and the lower mold are uniformly provided with aligned through holes, and the insertion rod slides through the through holes.

[0010] Furthermore, the top of the insert matches the shape of the inner wall of the lower mold.

[0011] Furthermore, the first wire rope and the second wire rope are respectively folded by a rotating shaft, which is rotatably mounted on a fixed frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention is a demolding device for mold processing. During the upward movement of the upper mold, the mounting plate drives the insertion rod to descend synchronously, forming a negative pressure environment between the upper mold and the lower mold. Air enters the lower mold through the through hole and pushes the thinner mold part, making it easier to remove the thinner mold part and avoiding deformation of the thinner mold part when it is removed.

[0021] like Figures 1 to 4 As shown, this utility model discloses a demolding device for mold processing, including: a frame 1, a lower mold 12, and a demolding mechanism 4 for facilitating the removal of thinner mold parts.

[0022] A workbench 13 is fixedly installed on the frame 1. A power distribution cabinet 3 is fixedly installed on the frame 1. A mounting frame 2 is fixedly installed on the workbench 13. A cylinder 14 is fixedly installed on the top of the mounting frame 2. Guide rails 11 are symmetrically fixedly installed on the mounting frame 2. The piston rod of the cylinder 14 is hinged to the lifting plate 5. The two ends of the lifting plate 5 are fixedly connected to the slider 6. The slider 6 is slidably installed on the guide rail 11. A connector is installed at the bottom of the lifting plate 5. The connector is connected to the connecting plate 7. An upper mold 8 is fixedly installed on the connecting plate 7. The upper mold 8 is aligned with the lower mold 12. A limit rod 10 is fixedly installed on the lower mold 12. The limit rod 10 slides and passes through the upper mold 8. A damping spring 9 is sleeved on the limit rod 10. The two ends of the damping spring 9 are fixedly connected to the upper mold 8 and the lower mold 12.

[0023] The demolding mechanism 4 includes: a first steel wire rope 41 and a second steel wire rope 42. The first steel wire rope 41 is fixedly connected to both ends of the bottom of the mounting plate 45, and the other end of the first steel wire rope 41 is fixedly connected to both ends of the bottom of the lifting plate 5. The first steel wire rope 41 passes through a rotating shaft 44 located below the mounting plate 45 and is folded. The second steel wire rope 42 is fixedly connected to both ends of the top of the mounting plate 45, and the other end of the second steel wire rope 42 is fixedly connected to both ends of the top of the lifting plate 5. The second steel wire rope 42 passes through a rotating shaft 44 located above the lifting plate 5 and is folded. The four rotating shafts 44 are respectively rotatably mounted. On two fixed brackets 43, one fixed bracket 43 is fixedly installed on the frame 1, and the other fixed bracket 43 is fixedly installed on the mounting bracket 2; the mounting plate 45 is evenly installed with insert rods 46, the mounting plate 45 is aligned with the fixed plate 47, the fixed plate 47 is fixedly installed with the lower mold 12, the fixed plate 47 and the lower mold 12 are evenly provided with aligned through holes 48, the insert rods 46 slide and pass through the through holes 48, when the upper mold 8 is inserted into the lower mold 12 to stamp the mold part, the insert rods 46 are completely inserted into the through holes 48, and the top of the insert rods 46 and the bottom of the inner wall of the lower mold 12 are in the same horizontal plane.

[0024] Furthermore, when the inner wall of the lower mold 12 is relatively complex, the top of the insert rod 46 matches the shape of the inner wall of the lower mold 12, so that the top of the insert rod 46 and the bottom of the inner wall of the lower mold 12 form a complete surface.

[0025] Furthermore, the diameter of the insert rod 46 is the same as that of the through hole 48, and the diameter of the insert rod 46 and the through hole 48 is smaller. The spacing between the through holes 48 is twice the diameter of the through hole 48. When the upper mold 8 rises, a negative pressure environment is formed in the sealed space formed by the inner walls of the upper mold 8 and the lower mold 12. Air can be evenly pushed through the through hole 48 to push the thinner mold part.

[0026] During the upward movement of the upper mold 8, the mounting plate 45 drives the insert rod 46 to descend synchronously, creating a negative pressure environment between the upper mold 8 and the lower mold 12. Air enters the lower mold 12 through the through hole 48 and pushes the thinner mold part, making it easier to remove and preventing deformation during removal. When the upper mold 8 slides in the lower mold 12, the upper mold 8 and the lower mold 12 fit tightly together. When the upper mold 8 descends in the lower mold 12 and completes the stamping, the descent of the lifting plate 5 pulls the mounting plate 45 upward through the second steel wire rope 42. The mounting plate 45 drives the insert rod 46 to insert into the through hole 48, gradually expelling the air from the sealed space formed by the inner walls of the lower mold 12 and the upper mold 8. When the upper mold 8 rises, the lifting plate 5 pulls the mounting plate 45 downward through the first steel wire rope 41. The mounting plate 45 drives the insert rod 46 to disengage from the through hole 48, allowing air to enter the lower mold 12 through the through hole 48 and push the thinner mold part.

[0027] Furthermore, a rectangular through slot is provided on one end of the fixed plate 47, and the through hole 48 is connected to the rectangular through slot, so that air can enter the lower mold 12 through the rectangular through slot and the through hole 48, without the insertion rod 46 needing to completely disengage from the through hole 48, thus improving the demolding speed.

[0028] Furthermore, fixed rods are symmetrically fixedly installed at the bottom of the workbench 13. The fixed rods slide and pass through both ends of the mounting plate 45 to position the mounting plate 45, so as to prevent the mounting plate 45 from shifting during the lifting and lowering process, which would prevent the insertion rod 46 from being inserted into the through hole 48.

[0029] Working principle:

[0030] When the piston rod of cylinder 14 pulls the lifting plate 5 upward, the lifting plate 5 pulls the connecting piece, the connecting piece pulls the connecting plate 7, and the connecting plate 7 pulls the upper mold 8 upward. When the upper mold 8 rises, the lifting plate 5 pulls the mounting plate 45 downward through the first steel wire rope 41. The mounting plate 45 drives the insertion rod 46 to disengage from the through hole 48. A negative pressure environment is formed in the sealed space formed by the inner walls of the upper mold 8 and the lower mold 12. Air can evenly push the thinner mold piece through the through hole 48, making the thinner mold piece easier to remove and avoiding deformation of the thinner mold piece when it is removed, thus improving the applicability of the device.
