Description

Technical Field

[0001] This utility model relates to the field of mold technology for hot press head machines, and in particular to a mold for a hot press head machine that facilitates the removal of the head. Background Technology

[0002] An end cap is a component used to seal the end of a container, isolating it from the internal and external media. It is also called an end cap. End caps of cylindrical containers are generally rotating shells. According to the shape of the end cap surface, they can be divided into convex, conical, flat, and combined types. Convex end caps refer to end caps with a convex outer surface, such as hemispherical, elliptical, dished, and spherical end caps without folded edges. Some gas cylinders use combined bottom end caps with convex surfaces facing inward, which can ensure strength and meet the requirements of safe use. The end cap hot press is a device for pressing end caps into shape.

[0003] The existing head hot press molds have the following shortcomings in use:

[0004] When the end cap is formed by pressing down on the end cap in the hot press, the heated end cap workpiece is first placed on the lower mold at the top of the support, and then pressed down by the upper mold to form the end cap. After forming, the end cap falls into the support, and the personnel use tools to pull it out. Then, a forklift is used to transport it to another location. However, when the end cap that has fallen into the support is taken out, the personnel use tools to pull it out. Since the end cap has a certain weight, it greatly increases the labor cost. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where, when a head is formed by pressing a head into shape using a head hot press, the heated head workpiece is first placed on the lower mold at the top of the support, and then pressed downwards by the upper mold. After being formed, the head falls into the support, and personnel use tools to pull it out and then use a forklift to transport it to another location. However, when removing the head that has fallen into the support, personnel use tools to pull it out, which greatly increases the labor cost due to the weight of the head. Therefore, this invention proposes a mold for a head hot press that facilitates the removal of the head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mold for a hot press for facilitating the removal of end caps includes a base. Four fixing rods are fixedly mounted on the top of the base. A single top plate is fixedly mounted on the top of each of the four fixing rods. A single movable plate is movably fitted onto each of the four fixing rods. A fixing block is fixedly mounted on the bottom of the movable plate. An mounting plate is fixedly mounted on the bottom of the fixing block. An upper mold is bolted to the bottom of the mounting plate. Two frames are fixedly mounted on the top of the base. A single support plate is welded to the top of the two frames. A through hole is formed at the center of the support plate. A lower mold is bolted to the top of the support plate and communicates with the through hole. A pull-out mechanism is provided on the base to pull out the end cap that falls out from the lower mold and the through hole.

[0008] To facilitate the removal of the end cap from the upper mold, a blocking mechanism is also included. When the upper mold rises, the blocking mechanism can block the end cap on the upper mold, making it easier for the end cap to fall off.

[0009] In one possible design, the pull-out mechanism includes a pull-out plate, a concave plate, and two support blocks. The bottoms of the two support blocks are fixedly connected to the top sides of the base, respectively. The concave plate is inverted concave, and its two ends are fixedly connected to the tops of the two support blocks, respectively. The pull-out plate is located between the two frames and directly below the support plate. Four movable wheels are fixedly installed at the bottom corners of the pull-out plate for easy movement. The movable wheels roll relative to the base. A motor is fixedly installed on one side of the concave plate. The output end of the motor passes through one side of the concave plate and is fixedly connected to a lead screw. One end of the lead screw is rotatably connected to the inner wall of one side of the concave plate. A movable block is slidably connected to the inner wall of the top of the concave plate. A lead screw nut is embedded in one side of the movable block, and the lead screw nut is threadedly connected to the lead screw. A U-shaped connecting frame is fixedly installed at the bottom of the movable block, and both ends of the connecting frame are fixedly connected to the bottom of the pull-out plate.

[0010] In one possible design, the blocking mechanism includes two electric push rods and two baffles. The fixed parts of the two electric push rods are fixedly connected to both sides of the support plate, and the baffles are L-shaped. The two baffles are fixedly connected to the telescopic parts of the two electric push rods, respectively.

[0011] In one possible design, frames for improving the stability of the baffle are welded to both sides of the bottom of the support plate. The frames are U-shaped, and one end of the baffle is slidably connected to the inner wall of the frame.

[0012] In one possible design, a driving component for driving the upper mold to press down is fixedly installed on the top of the top plate, and the telescopic part of the driving component passes through the bottom of the top plate and is fixedly connected to the top of the movable plate.

[0013] In one possible design, a stop plate is fixedly installed on one side of both of the frames to block the pull-out plate.

[0014] In this application, during use, the heated workpiece is placed on top of the lower mold. The drive unit is activated, and its telescopic part extends downward, pushing the moving plate downward along the four fixed rods. Since the fixed block is fixed to the bottom of the moving plate, the mounting plate is fixed to the bottom of the fixed block, and the upper mold is fixed to the bottom of the mounting plate, the upper mold moves downward along with the moving plate, gradually approaching the lower mold. When the upper mold contacts the lower mold, pressure is applied to the end cap material placed in the lower mold for thermoforming. During the forming process, the end cap moves downward along the through hole and is positioned above the pull-out plate, making the horizontal position of the end cap on the upper mold lower than the baffle. Then, the two electric push rods are activated, and their telescopic parts retract, driving the two baffles to move towards the upper mold, so that one end of the two baffles abuts against the top of the end cap. Figure 5 (As shown), then the telescopic part of the drive component begins to retract upwards, driving the moving plate, fixed block, mounting plate, and upper mold to move upwards together. As the upper mold continues to rise, the end cap is blocked by the baffle, thus detaching from the upper mold and falling to the top of the pull-out plate. Then the motor is started, and the output end of the motor begins to rotate, driving the lead screw to rotate within the concave plate. The rotation of the lead screw drives the moving block to move along the direction of the lead screw. The movement of the moving block drives the U-shaped connecting frame to move. The movement of the connecting frame drives the pull-out plate to move, pulling the end cap out from the bottom of the lower mold, the support plate, and the two frames. After the end cap is removed, the motor is started in reverse, causing the lead screw to... The lever rotates in the opposite direction, causing the moving block, connecting frame, and pull-out plate to move in the opposite direction. When the pull-out plate moves to below the lower die, it can be stopped by the stop plate, so that the pull-out plate is directly below the lower die. The driving component can be a hydraulic cylinder, an electric push rod, or a pneumatic cylinder. The hydraulic cylinder requires an external hydraulic pump station to operate, the pneumatic cylinder requires an air source, and the electric push rod requires a power source. The motor can be a stepper motor, which can rotate in both directions. The type of motor can be selected according to needs. It should be noted that the motor, electric push rod, and driving component require an external power supply and an external controller to operate.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model, the mold for a hot press for facilitating the removal of the end cap is provided. Through the pull-out mechanism, the screw is driven by a motor to rotate, which in turn moves the pull-out plate. This allows the end cap to be automatically pulled out from the bottom of the lower mold, the support plate, and the two frames without the need for manual pulling. This significantly reduces the labor intensity of personnel and improves work efficiency.

[0017] In this utility model, the mold for a hot press for facilitating the removal of the end cap is provided with a blocking mechanism. When the upper mold rises, an electric push rod pushes a baffle to move and block the end cap on the upper mold, so that the end cap can be smoothly removed from the upper mold.

[0018] In this invention, the pull-out mechanism can automatically pull the end cap out from the bottom of the lower mold, the support plate, and the two frames, eliminating the need for manual pulling and significantly reducing the labor intensity and improving work efficiency. The blocking mechanism can hold the end cap on the upper mold, allowing it to fall off smoothly from the upper mold. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] Referring to 1-5, a mold includes: a base 1, a top plate 4, a movable plate 3, an upper mold 6, a lower mold 9, a pull-out mechanism, a blocking mechanism, and a driving component 5. Through the coordinated work of these parts, the thermoforming of the end cap and the automatic detachment and pull-out of the end cap after forming are achieved, reducing manual labor intensity and improving production efficiency. The base 1 provides a stable support foundation for the entire mold. Four fixed rods 2 are fixedly installed on the top of the base 1, arranged in a rectangular shape, and their tops are all fixedly connected to the same top plate 4. The same movable plate 3 is movably sleeved on the four fixed rods 2, and the movable plate 3 can move vertically up and down on the fixed rods 2.

[0028] A fixing block 18 is fixedly installed at the bottom of the movable plate 3, and the mounting plate 8 is fixedly connected to the bottom of the fixing block 18. An upper mold 6 is fixedly installed at the bottom of the mounting plate 8 by bolts. This detachable connection method facilitates the replacement and maintenance of the upper mold 6 to meet the production needs of different specifications of end caps. Two frames 19 are fixedly installed at the top of the base 1, and the two frames 19 are symmetrically distributed. The same support plate 7 is welded to the top of the two frames 19, and a through hole is opened at the center of the support plate 7. A lower mold 9 is fixedly installed at the top of the support plate 7 by bolts, and the lower mold 9 is connected to the through hole, allowing the end cap to move smoothly downwards through the through hole during the hot pressing process.

[0029] The pull-out mechanism is used to pull out the end cap that has fallen out of the lower mold 9 and the through hole. This mechanism includes a pull-out plate 12, a concave plate 14, and two support blocks. The bottoms of the two support blocks are fixedly connected to the top sides of the base 1, respectively. The concave plate 14 is inverted concave, and its two ends are fixedly connected to the tops of the two support blocks, thus stably mounting the concave plate 14 above the base 1. The pull-out plate 12 is located between the two frames 19 and directly below the support plate 7. Four movable wheels are fixedly installed at the bottom corners of the pull-out plate 12 for easy movement. The movable wheels roll against the base 1, allowing the pull-out plate 12 to move smoothly on the base 1. A motor 13 is fixedly installed on one side of the concave plate 14. The output end of the motor 13 passes through one side of the concave plate 14 and is fixedly connected to a lead screw 15. One end of the lead screw 15 is rotatably connected to the inner wall of one side of the concave plate 14, ensuring that the lead screw 15 can rotate stably within the concave plate 14. A movable block 20 is slidably connected to the top inner wall of the concave plate 14. A lead screw nut is embedded in one side of the movable block 20, and the lead screw nut is threadedly connected to the lead screw 15. When the motor 13 drives the lead screw 15 to rotate, the lead screw nut converts the rotational motion of the lead screw 15 into the linear motion of the movable block 20, causing the movable block 20 to move along the direction of the lead screw 15. A U-shaped connecting frame 16 is fixedly installed at the bottom of the movable block 20, and both ends of the connecting frame 16 are fixedly connected to the bottom of the pull-out plate 12. Therefore, the movement of the movable block 20 will drive the connecting frame 16 and the pull-out plate 12 to move together, realizing the pull-out operation of the end cap.

[0030] The blocking mechanism is used to block the end cap on the upper mold 6 when the upper mold 6 rises, facilitating the detachment of the end cap. This mechanism includes two electric push rods 11 and two baffles 10. The fixed parts of the two electric push rods 11 are fixedly connected to both sides of the support plate 7. The baffles 10 are L-shaped, and each baffle 10 is fixedly connected to the telescopic parts of the two electric push rods 11. When the telescopic parts of the electric push rods 11 extend or retract, they drive the baffles 10 to move. To improve the stability of the baffles 10, frames 17 are welded to both sides of the bottom of the support plate 7 to enhance the stability of the baffles 10. The frames 17 are U-shaped, and one end of the baffle 10 is slidably connected to the inner wall of the frame 17, making the baffles 10 more stable during movement and accurately blocking the end cap.

[0031] This application is for use in the field of hot press molds for end caps, but can also be used in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figures 1-5 An improvement based on Embodiment 1: a mold for a hot press of end caps that facilitates end cap removal, which is used in the field of molds for hot presses of end caps.

[0034] A driving component 5 for driving the upper mold 6 downward is fixedly installed on the top of the top plate 4. The telescopic part of the driving component 5 passes through the bottom of the top plate 4 and is fixedly connected to the top of the movable plate 3. The driving component 5 can be selected from hydraulic cylinders, electric push rods, or pneumatic cylinders, and the user can choose according to actual production needs and site conditions. For example, if a hydraulic cylinder is selected, an external hydraulic pump station is required during use; if a pneumatic cylinder is selected, an air source needs to be connected; if an electric push rod is selected, it can be used simply by connecting a power source.

[0035] Each of the two frames 19 has a stop plate fixedly installed on one side to block the pull-out plate 12. When the pull-out plate 12 moves below the lower mold 9, the stop plate can limit the pull-out plate 12, so that the pull-out plate 12 is accurately located directly below the lower mold 9, which is convenient for catching the falling end cap.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 13, electric push rod 11 and drive component 5 are commonplace and belong to conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
