Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically a production mold that is easy to demold. Background Technology

[0002] Stamping is a metalworking process that uses stamping equipment and dies to apply external force to metal sheets, strips, tubes, or profiles, causing them to undergo plastic deformation or separation, thereby obtaining parts or semi-finished products with specific shapes, dimensions, and properties. Stamping typically requires the use of production dies. However, existing production dies often result in low efficiency because the pressure exerted on the product within the die after stamping makes it difficult to demold and remove the product. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a production mold that is easy to demold, which solves the problem that after the stamping is completed, the product inside the production mold is under great pressure, making it difficult to demold and resulting in low work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a production mold that facilitates demolding, comprising a box body, four electric push rods fixedly connected inside the box body, a movable plate fixedly connected to the output ends of two electric push rods, an inclined plate fixedly connected to the top of the movable plate, a cylinder fixedly connected inside the box body, a movable rod slidably connected to the cylinder body, a lifting plate fixedly connected to the top of the movable rod, and two brackets fixedly connected to both sides of the lifting plate;

[0005] The bracket is rotatably connected to four rollers. The inclined plate is in contact with two of the rollers. Several ejector rods are fixedly connected to the top of the lifting plate. The ejector rods are evenly distributed on the top of the lifting plate. The ejector rods are slidably connected to the box body. A lower mold is fixedly connected to the top of the box body. An upper mold is provided on the top of the box body.

[0006] As a further embodiment of this utility model: four support columns are fixedly connected to the top of the box body, the four support columns are located at the four corners of the top of the box body, and a top plate is fixedly connected to the top of the four support columns.

[0007] As a further embodiment of this utility model: a hydraulic rod is fixedly connected to the top plate, and the output end of the hydraulic rod is fixed to the upper mold.

[0008] As a further embodiment of this utility model: the lower mold has a plurality of through holes, the through holes being positioned corresponding to the ejector rods.

[0009] As a further embodiment of this utility model: a spring is sleeved on the movable rod, and a circular plate is fixedly connected to the bottom end of the movable rod.

[0010] As a further embodiment of this utility model: one end of the spring is fixedly connected to the top of the circular plate, and the other end of the spring is fixedly connected to the inside of the cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This easy-to-demold production mold, through the setting of electric push rod, inclined plate, moving plate, lower mold and ejector rod, places the blank on the top of the lower mold, and activates the hydraulic rod to drive the upper mold to move down to stamp the blank. The stamped product will be located inside the lower mold. At this time, the electric push rod is activated to drive the moving plate and inclined plate to move, so that the two inclined plates are brought closer to each other. Under the action of the inclined surface of the inclined plate, the inclined plate will push the roller, causing the roller, lifting plate, ejector rod and moving rod to move up. The moving rod drives the circular plate to move up, and the circular plate will compress the spring. At the same time, the ejector rod moves up to push the product inside the lower mold, completing the product demolding. This mold, by pushing the product inside the lower mold out by the upward movement of the ejector rod, facilitates demolding and improves work efficiency.

[0013] 2. This easy-to-demold production mold, through the setting of a circular plate, a movable rod and a spring, after the product is demolded, the electric push rod is activated to drive the moving plate and the inclined plate to move, so that the two inclined plates move away from each other. During the process of the two inclined plates moving away from each other, the roller gradually loses the squeezing effect of the inclined plates, so that the spring returns to its original position and pushes the circular plate down. The circular plate drives the movable rod, the lifting plate and the ejector rod to move down, so that the ejector rod returns to its original position. This mold uses the return action of the spring to assist the ejector rod to move down, thereby realizing the rapid return of the ejector rod, which is convenient for the next use.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a production mold that is easy to demold, including a box body 1. Four electric push rods 7 are fixedly connected inside the box body 1. The output ends of two electric push rods 7 are fixedly connected to a moving plate 9. An inclined plate 8 is fixedly connected to the top of the moving plate 9. Due to the inclined surface design of the inclined plate 8, when the two inclined plates 8 approach each other, the inclined surface of the inclined plate 8 will give the roller 16 an upward force, which facilitates the upward movement of the roller 16, the lifting plate 14 and the ejector rod 17. Four support columns 2 are fixedly connected to the top of the box body 1. The four support columns 2 are located at the four corners of the top of the box body 1, and the top of the four support columns 2 are fixedly connected to a top plate 3.

[0021] A cylinder 10 is fixedly connected inside the housing 1. A movable rod 11 is slidably connected to the cylinder 10. A spring 12 is sleeved on the movable rod 11. Because of the spring 12, the spring 12 assists the ejector rod 17 to move down, thereby realizing the quick reset of the ejector rod 17 for easy use next time. A circular plate 13 is fixedly connected to the bottom end of the movable rod 11. Because of the circular plate 13, when the circular plate 13 moves upward in a predetermined direction, it can compress the spring 12, thereby ensuring the smooth progress of subsequent work. A lifting plate 14 is fixedly connected to the top end of the movable rod 11. Two brackets 15 are fixedly connected to both sides of the lifting plate 14.

[0022] Rollers 16 are rotatably connected to the support 15. Because of the rollers 16, the sliding friction between the lifting plate 14 and the inclined plate 8 is transformed into rolling friction, thereby reducing friction, decreasing wear on the inclined plate 8 and the lifting plate 14, and improving the smoothness of movement. There are four rollers 16, with the inclined plate 8 in contact with two of them. Several ejector rods 17 are fixedly connected to the top of the lifting plate 14. Because of the ejector rods 17, they cooperate with the movable rods 11. When the lifting plate 14 moves, the ejector rods 17 slide on the housing 1, while the movable rods 11 slide on the cylinder 10. The ejector rods 17 and the movable rods 11 move together. The lifting plate 14 is limited and guided, improving the stability and accuracy of its movement. Several ejector rods 17 are evenly distributed on the top of the lifting plate 14. By ejecting the product through these evenly distributed ejector rods 17, the product can be subjected to uniform force, and the pressure on each part is basically the same. This avoids the possibility of excessive local stress due to uneven force, and effectively prevents the product from being damaged due to uneven force. The ejector rods 17 are slidably connected to the box body 1. The lower mold 6 is fixedly connected to the top of the box body 1. Several through holes 18 are opened on the lower mold 6, and the through holes 18 correspond to the positions of the ejector rods 17.

[0023] The top of the box 1 is provided with an upper mold 5, and a hydraulic rod 4 is fixedly connected to the top plate 3. The output end of the hydraulic rod 4 is fixed to the upper mold 5. One end of the spring 12 is fixedly connected to the top of the circular plate 13, and the other end of the spring 12 is fixedly connected to the inside of the cylinder 10.

[0024] The working principle of this utility model is as follows:

[0025] The blank is placed on top of the lower mold 6. The hydraulic rod 4 is activated to drive the upper mold 5 to move down and stamp the blank. The stamped product will be located inside the lower mold 6. At this time, the electric push rod 7 is activated to drive the moving plate 9 and the inclined plate 8 to move, so that the two inclined plates 8 move closer to each other. Under the action of the inclined surface of the inclined plate 8, the inclined plate 8 will push the roller 16, causing the roller 16, the lifting plate 14, the ejector rod 17 and the movable rod 11 to move up. The movable rod 11 drives the circular plate 13 to move up, and the circular plate 13 will compress the spring 12. At the same time, the ejector rod 17 moves up to eject the product inside the lower mold 6, completing the demolding of the product.

[0026] After the product is demolded, the electric push rod 7 is activated to drive the moving plate 9 and the inclined plate 8 to move, so that the two inclined plates 8 move away from each other. During the process of the two inclined plates 8 moving away from each other, the roller 16 gradually loses the squeezing effect of the inclined plate 8, so that the spring 12 returns to its original position and pushes the circular plate 13 to move down. The circular plate 13 drives the movable rod 11, the lifting plate 14 and the ejector rod 17 to move down, so that the ejector rod 17 returns to its original position.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
