Description

Technical Field

[0001] This utility model relates to the field of contour mark production technology, and in particular to a contour mark stamping die that is easy to demold. Background Technology

[0002] Delineators are markings used on roads, railways, and other transportation infrastructure, primarily to indicate lane boundaries and directions. These markings are typically placed along road edges, providing clear visual guidance at night or in low visibility conditions, thereby improving driving safety. Delineator stamping dies are tools used to manufacture delineators. They typically employ stamping processes to shape metal sheets or plastic materials into the required shapes and sizes using dies. Stamping is an efficient production method suitable for mass production, ensuring the accuracy and consistency of delineators. However, most existing delineator stamping dies still have problems that need to be solved.

[0003] Most existing contour stamping dies lack an effective unloading mechanism. During the stamping process, the surface of the contour material may adhere to the die due to factors such as temperature and material properties. Furthermore, the small gap between the die and the workpiece increases the difficulty of removing the stamped workpiece, requiring more time and effort to remove it, which to some extent affects work efficiency. Therefore, it is necessary to design a contour stamping die that is easy to demold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a contour stamping die that facilitates demolding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A contour stamping die for easy demolding includes a lower die base, a lower mold fixedly connected to the top of the lower die base, an upper die set on the top of the lower die, an upper die base fixedly connected to the top of the upper die, fixed plates fixedly connected to both sides of the upper die base, two insert rods fixedly connected to the bottom of the fixed plates, sleeves sleeved on the insert rods, the insert rods slidably connected to the sleeves, the sleeves slidably connected to the lower die base, and the bottom of the two sleeves on the same side fixedly connected to the same sleeve plate, the sleeve plate being provided with two... A first limiting rod is slidably connected to a sleeve plate. A first spring is sleeved on the first limiting rod. A support plate is fixedly connected to one side of the first limiting rod. One side of the support plate is inclined. The tops of two support plates on the same side are fixedly connected to the same pressure plate. One side of the pressure plate is inclined. A top plate is provided on the top of the pressure plate. The top plate is fixedly connected to the bottom of the lower mold base. A horizontal plate is provided at the bottom of the lower mold base. Four connecting rods are fixedly connected to the top of the horizontal plate. All four connecting rods pass through... The connecting rods slidably connect the lower mold base and the lower mold, and the tops of the four connecting rods are all fixedly connected to the same mold core. Because the upper mold rises while the mold core rises to eject the workpiece from the lower mold, the support plate rises along with the upper mold, carrying the horizontal plate, which in turn carries the connecting rods. The connecting rods then drive the mold core to rise, ejecting the formed contour mark workpiece, which the operator can then remove. This effectively solves the problem mentioned in the background art that most existing contour stamping dies lack an effective unloading mechanism. During the stamping process, the surface of the contour mark material may adhere to the mold due to factors such as temperature and material properties, and the gap between the mold and the workpiece is small, increasing the difficulty of removing the stamped workpiece and requiring considerable time and effort, thus affecting work efficiency. This solution achieves the technical effect of simple operation, easy removal of the stamped contour mark from the mold, reduced demolding time and effort, and effectively improved work efficiency.

[0007] As a further embodiment of this utility model, each of the four connecting rods is fitted with a second spring, which enables the horizontal plate and the die core to be reset and continue the stamping operation.

[0008] As a further embodiment of this utility model, a base is fixedly connected to the outer wall of the lower mold base.

[0009] As a further embodiment of this utility model, a marking line is provided on the outer wall of the bottom end of the insertion rod.

[0010] As a further embodiment of this utility model, four second limiting rods arranged in a square are fixedly connected to the top of the lower mold base. The second limiting rods pass through the upper mold base and are slidably connected to the upper mold base. By setting the second limiting rods, the stability of the upper mold during movement is ensured.

[0011] As a further embodiment of this utility model, a fixed base is fixedly connected to the top of the upper mold base.

[0012] As a further embodiment of this utility model, the fixing base is fixed to the output end of the drive component by screws.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model addresses the issue of existing contour stamping dies lacking effective unloading mechanisms. Specifically, it addresses the challenges of material adhesion during stamping, where the contour material may adhere to the die due to temperature and material properties. Furthermore, the small gap between the die and the workpiece increases the difficulty of removing the stamped workpiece, requiring considerable time and effort and impacting work efficiency. This invention simplifies operation, facilitates the removal of stamped contours from the die, reduces the time and effort required for demolding, and effectively improves work efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and implementing regulations.

[0024] Reference Figure 1 - Figure 6A contour stamping die for easy demolding includes a lower die base 1, a lower die 2 fixedly connected to the top of the lower die base 1, an upper die 3 set on the top of the lower die 2, an upper die base 4 fixedly connected to the top of the upper die 3, fixed plates 5 fixedly connected to both sides of the upper die base 4, two insert rods 6 fixedly connected to the bottom of the fixed plates 5, sleeves 7 sleeved on the insert rods 6, the insert rods 6 slidably connected to the sleeves 7, the sleeves 7 slidably connected to the lower die base 1, and the bottom of the two sleeves 7 on the same side fixedly connected to the same sleeve plate 8, the sleeve plate 8 being provided with two first limiters. Rod 9, first limiting rod 9 is slidably connected to sleeve plate 8, first limiting rod 9 is sleeved with first spring 10, support plate 11 is fixedly connected to one side of first limiting rod 9, one side of support plate 11 is inclined, the top of two support plates 11 on the same side is fixedly connected to the same pressure plate 12, one side of pressure plate 12 is inclined, top plate 1201 is provided on top of pressure plate 12, top plate 1201 is fixedly connected to the bottom of lower mold base 1, bottom of lower mold base 1 is provided with horizontal plate 13, top of horizontal plate 13 is fixedly connected to four connecting rods 14, four connecting rods 14 are fixedly connected to the top of horizontal plate 13. All rods 14 pass through the lower mold base 1 and the lower mold 2. The connecting rods 14 slidably connect the lower mold base 1 and the lower mold 2. The top of each of the four connecting rods 14 is fixedly connected to the same mold core 15. Because the upper mold is raised while the mold core is raised to eject the workpiece from the lower mold, when the upper mold rises, the support plate also rises. The support plate will raise the horizontal plate, which will raise the connecting rod. The connecting rod will then drive the mold core to rise and eject the formed outline workpiece. The operator can then remove it. This effectively solves the problem mentioned in the background art that most existing outline stamping dies lack an effective unloading mechanism. During the stamping process, the surface of the outline material may adhere to the mold due to factors such as temperature and material properties. In addition, the gap between the mold and the workpiece is small, which increases the difficulty of removing the stamped workpiece. It requires more time and effort to remove the workpiece, which affects the efficiency of the work to a certain extent. This achieves the technical effect of simple operation, easy removal of the stamped outline from the mold, reduced demolding time and effort, and effective improvement of work efficiency.

[0025] In this embodiment, each of the four connecting rods 14 is fitted with a second spring 16, which enables the horizontal plate and the die core to be reset so that the stamping work can continue.

[0026] In this embodiment, a base 17 is fixedly connected to the outer wall of the lower mold base 1.

[0027] In this embodiment, a marking line 601 is provided on the outer wall of the bottom end of the insertion rod 6.

[0028] In this embodiment, four second limiting rods 18 arranged in a square are fixedly connected to the top of the lower mold base 1. The second limiting rods 18 pass through the upper mold base 4 and are slidably connected to the upper mold base 4. By setting the second limiting rods 18, the stability of the upper mold during movement is ensured.

[0029] In this embodiment, a fixing seat 19 is fixedly connected to the top of the upper mold base 4.

[0030] In this embodiment, the mounting base 19 is fixed to the output end of the drive unit by screws.

[0031] Working principle: Before using this device, fix the fixed seat 19 to the output end of the hydraulic cylinder using screws. The outline marker material can be injected into the lower mold 2. The hydraulic system extends the output end of the hydraulic cylinder, causing the fixed seat 19 to descend. The fixed seat 19 then drives the upper mold seat 4 to descend, which in turn drives the upper mold 3 to descend for stamping. The cooperation between the upper mold 3 and the lower mold 2 shapes the outline marker material. When the upper mold seat 4 moves, it moves along the second limit rod 18, ensuring the stability of the upper mold seat 4 during movement, which in turn ensures the stability of the upper mold 3 during movement. The descent of the upper mold seat 4 also drives... As the fixed plate 5 descends, it causes the insert rod 6 to descend as well. When the bottom of the insert rod 6 contacts the sleeve plate 8, its continued descent causes the sleeve plate 8 to descend as well. The sleeve plate 8 then causes the first limiting rod 9 to descend, which in turn causes the support plate 11 to descend. The inclined edge of the support plate 11 contacts the horizontal plate 13. At this point, the bottom of the mold core 15 contacts the inner wall of the lower mold 2, causing the horizontal plate 13 to be compressed and descend. As the insert rod 6 continues to descend, the support plate 11 moves closer to the sleeve plate 8 and continues to descend until it passes the horizontal plate 13. When the support plate 11 moves closer to the sleeve plate 8, it compresses the first spring 10, causing the first spring 10 to contract. After passing the horizontal plate 13, the first spring 10 extends, placing the support plate 11 at the bottom of the horizontal plate 13. After completing the stamping operation, the output end of the hydraulic cylinder retracts, causing the upper mold 3 to rise, which in turn causes the insert rod 6 to rise. After the marking line 601 passes the sleeve 7, the insert rod 6 contacts the top inner wall of the sleeve 7. At this point, the insert rod 6 continues to rise, causing the support plate 11 to rise. The support plate 11 then drives the horizontal plate 13 to rise, which in turn drives the connecting rod 14 to rise. Simultaneously, the horizontal plate 13 compresses the second spring 16, causing it to contract. The rising connecting rod 14 then drives the mold core 15 to rise, thus... The outline formed in the lower mold 2 is ejected for demolding, making it easy for the operator to remove the outline. The rise of the support plate 11 will also drive the pressure plate 12 to rise. If the pressure plate 12 continues to rise when its inclined edge contacts the top plate 1201, the pressure plate 12 will move a distance towards the sleeve 7, which will allow the support plate 11 to move closer to the sleeve plate 8 again, so that the sleeve plate 8 is no longer directly below the horizontal plate 13. At this time, the second spring 16 will extend, which will allow the horizontal plate 13 to fall back to its initial position, and the mold core 15 will also return to its initial position. The outline stamping production work can then be carried out in the same manner.
