Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision molds, specifically to a precision mold with a simple ejection mechanism. Background Technology
[0002] Precision molds are molds capable of precisely shaping complex shapes and requiring extremely high dimensional accuracy. They are widely used in fields such as electronics, optical instruments, medical devices, and aerospace. Simplified ejection mechanisms, on the other hand, are based on traditional ejection structures (such as rigid ejection and elastic ejection) and utilize innovative designs such as mechanical linkages and reset components to simplify the ejection process and improve ejection speed and stability.
[0003] Traditional precision molds mostly use pneumatic ejectors to eject materials from the product. However, ejector pin systems require pneumatic system components such as air pipes and valves, resulting in a relatively complex structure. This not only increases the difficulty of mold design and manufacturing but also raises the cost. Furthermore, pneumatic systems require regular maintenance and upkeep, such as cleaning the air passages and replacing seals. In addition, pneumatic components (such as valves) have a relatively high failure rate, leading to high repair and replacement costs when malfunctions occur.
[0004] Therefore, it is necessary to invent a precision mold with a simple unloading mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a precision mold with a simple ejection mechanism. The product requiring precision machining is placed above a flip plate, and then the upper mold is lowered and moved hydraulically. The upper mold's punch presses against the middle of the product to bend it. Simultaneously, the punch presses against the product, and the insert block inserts into the slot, pushing the contact plate down to press the damping rod. The flip plate, losing its support, flips over. When the stamping is complete and the upper mold leaves the mold base, the damping rod below the contact plate rebounds, pushing the flip plate and the internal product out for ejection. This method is faster and simpler than traditional pneumatic methods, addressing the problem mentioned in the background art where traditional precision molds mostly use pneumatic ejection pins to eject products. Ejector pin methods require air pipes, valves, and other pneumatic system components, resulting in a relatively complex structure. This not only increases the design and manufacturing difficulty of the mold but also raises its cost. Furthermore, pneumatic systems require regular maintenance, such as cleaning the air lines and replacing seals. In addition, pneumatic components have a relatively high failure rate, leading to high repair and replacement costs in case of failure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision mold with a simple unloading mechanism, including a mold base; A flip plate is rotatably connected to both sides inside the mold base. Blocks are fixedly connected to both sides inside the mold base. Damping rods are fixedly installed on both sides inside the mold base. A contact plate is fixedly connected to the upper end of the damping rod. Connecting blocks are fixedly connected to both sides of the contact plate. Slots are opened on the upper two sides of the mold base. A connecting rod is fixed to both sides of the mold base. A top plate is slidably connected to the outside of the connecting rod. An upper mold is fixedly connected to the lower end of the top plate. A punching head is fixedly connected to the lower part of the upper mold. Insert blocks are fixedly connected to both sides of the upper mold.
[0007] Preferably, the upper two sides of the mold base are provided with docking grooves, and the lower two sides of the upper mold are fixedly connected with docking columns, and the docking grooves and docking columns are used in conjunction.
[0008] Preferably, the abutment plate is slidably connected to the inside of the mold base, and the connecting block is located inside the slot.
[0009] Preferably, the inserts on both sides of the upper mold are movably inserted into the slots on both sides above the mold base, and the bottom of the inserts abuts against the connecting block.
[0010] Preferably, the front and rear surfaces of the mold base are provided with limit grooves, the front and rear surfaces of the mold base are slidably connected to sliders, the rear side of the sliders is fixedly connected to springs, and the upper side of the sliders is fixedly connected to push plates with the outer side of the push plates being set at an angle.
[0011] Preferably, a limiting block is fixedly connected below the stamping head, and the inner side of the limiting block is set at an angle, and the limiting block abuts against the rear side of the push plate.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the arrangement of a flap, damping rod, contact plate, upper die, punch head, and insert block, enables rapid product unloading, improving unloading efficiency. By placing the product requiring precision machining above the flap, the upper die is then hydraulically pushed downwards and moves. The punch head of the upper die presses down on the middle of the product to perform bending. While the punch head is pressing down on the product, the insert block is simultaneously inserted into the slot, pushing the contact plate down to press down the damping rod. The flap, losing its support, also flips over. When the punching is finished and the upper die leaves the die base, the damping rod below the contact plate rebounds, pushing the flap and the internal product out for unloading. This method is faster and simpler than the traditional pneumatic method. Attached Figure Description

Detailed Implementation
[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figure 1-5 The precision mold shown includes a mold base 1, which has a simple unloading mechanism. Flip plate 2 is rotatably connected to both sides inside the mold base 1. Blocks 3 are fixedly connected to both sides inside the mold base 1. Damping rods 4 are fixedly installed on both sides inside the mold base 1. Abutment plate 5 is fixedly connected to the upper end of the damping rod 4. Connecting blocks 6 are fixedly connected to both sides of the abutment plate 5. Slots 7 are opened on the upper two sides of the mold base 1. Connecting rod 13 is fixed on both sides of mold base 1. Top plate 14 is slidably connected to the outside of connecting rod 13. Upper mold 15 is fixedly connected to the lower end of top plate 14. Punching head 16 is fixedly connected to the lower part of upper mold 15. Insert blocks 17 are fixedly connected to both sides of upper mold 15. By placing the product that needs to be precision processed on top of flip plate 2, and then pushing upper mold 15 down and moving by hydraulic means, the punching head 16 of upper mold 15 presses on the middle of the product to perform bending. When the punching head 16 presses on the product, the insert blocks 17 are also inserted into slot 7 to push the abutment plate 5 down and press down the damping rod 4. Flip plate 2 loses support and flips. When the punching is finished, when upper mold 15 leaves mold base 1, the damping rod 4 under the abutment plate 5 rebounds and pushes flip plate 2 and the product inside to be ejected. This is faster and simpler than the traditional pneumatic method.
[0018] like Figure 1 and Figure 5 As shown, the upper two sides of the mold base 1 are provided with docking grooves 8, and the lower two sides of the upper mold 15 are fixedly connected with docking columns 18. The docking grooves 8 and docking columns 18 are used together. When the upper mold 15 descends, the four sets of docking columns 18 are inserted into the docking grooves 8 inside the mold base 1 to complete the docking of the two.
[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the contact plate 5 is slidably connected to the mold base 1, and the connecting block 6 is located inside the slot 7. When the upper mold 15 descends, it drives the insert block 17 to insert into the slot 7 above the mold base 1. When the insert block 17 contacts the connecting block 6 and the contact plate 5, it will squeeze the damping rod 4 below, so that the flip plate 2 loses the contact of the contact plate 5. At the same time, after the contact plate 5 loses the contact, it uses the damping rod 4 below to rebound and push the contact plate 5 and the flip plate 2, so that the flip plate 2 flips over to remove the product.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the insert blocks 17 on both sides of the upper mold 15 are movably inserted into the slots 7 on both sides of the upper mold base 1. The bottom of the insert block 17 abuts against the connecting block 6. When the insert block 17 contacts the connecting block 6 and the contact plate 5, it will squeeze the damping rod 4 below, so that the flip plate 2 loses its contact, thus facilitating the precision processing of the product.
[0021] like Figure 4 and Figure 5As shown, limit grooves 9 are provided on the front and rear surfaces of the mold base 1. Slider 10 is slidably connected to the front and rear surfaces of the mold base 1. Spring 11 is fixedly connected to the rear side of slider 10. Push plate 12 is fixedly connected above slider 10 and the outer side of push plate 12 is set at an angle. When the upper mold 15 descends, it drives the limit blocks 19 on the front and rear sides to squeeze and push push plate 12, so that push plate 12 moves to position the product in the middle and avoids the situation of displacement.
[0022] like Figure 4 and Figure 5 As shown, a limiting block 19 is fixedly connected to the lower part of the stamping head 16, and the inner side of the limiting block 19 is set at an angle. The limiting block 19 abuts against the rear side of the push plate 12. When the limiting block 19 descends, it uses the inner angle to contact the angle of the rear side of the push plate 12, thereby squeezing and pushing the push plate 12 to move to the front and rear sides of the product, thereby positioning the product.
[0023] The working principle of this utility model is as follows: First, the product is placed above the flip plate 2 inside the mold base 1. Then, the top plate 14 and the upper mold 15 are pneumatically pushed down. During the descent, the limiting blocks 19 on the front and rear sides contact the rear angle of the push plate 12 with their inner bevels, thereby squeezing and pushing the push plate 12 to move towards the front and rear sides of the product, thus positioning the product. Next, the inserts 17 on both sides of the upper mold 15 are inserted into the slots 7 on both sides inside the mold base 1, pushing the abutment plate 5 down to press down the damping rod 4. The flip plate 2 loses its support and flips over. At this time, the punch head 16 contacts the product for precision bending. The angle of rotation is exactly against the stop block 3. Finally, when the upper mold 15 leaves the mold base 1 after the stamping is completed, the connecting blocks 6 on both sides of the contact plate 5 lose the contact of the insert block 17. The damping rod 4 below rebounds and pushes the flip plate 2 and the product inside to be ejected. This is faster and simpler than the traditional pneumatic method. At the same time, after the limit block 19 disengages from the limit groove 9 inside the front and rear sides of the mold base 1, the push plate 12 also loses the contact and rebounds using the spring 11 below, allowing the push plate 12 to disengage from both sides of the product. Finally, the staff takes out the ejected product. In this way, the use process of the precision mold with a simple ejection mechanism is completed.
[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
