Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber product processing technology, specifically a rubber hydraulic molding device. Background Technology
[0002] Rubber products refer to various rubber products made from natural and synthetic rubber, and also include rubber products made from recycled waste rubber; a hydraulic molding device is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source to complete certain mechanical actions as a productive force; in the processing and production of rubber products, hydraulic molding devices are often used to press rubber raw materials into rubber products.
[0003] The published patent document CN215589765U discloses a hydraulic device for rubber product manufacturing. The top block of this patent document can eject the finished product from the mold without the need for manual demolding by the operator, which improves the demolding effect of the hydraulic device, reduces the labor intensity of the operator, and improves the working efficiency of the hydraulic device, effectively meeting the needs of the operator. However, the unloading method of using the top block to lift the molded product is prone to deformation of the lifted rubber product due to the softness of the rubber product itself. Utility Model Content
[0004] The purpose of this invention is to provide a rubber hydraulic molding device that solves the problems mentioned in the background art.
[0005] This application provides a rubber hydraulic molding device, including an operating table. A bellows is fixedly installed on the top of the operating table, and a lower mold and an upper mold are arranged above the operating table. An air pump is fixedly installed at the bottom of the operating table, and an air inlet pipe passes through the bottom of the operating table. The output end of the air pump is connected to the lower end of the air inlet pipe, and the upper end of the air inlet pipe communicates with the interior of the bellows. Several air ducts pass through and communicate with the top of the bellows. The upper end of each air duct passes through the bottom of the lower mold. A matching pipe plug is provided on the upper side of the interior of each air duct, and U-shaped parts are symmetrically fixedly connected to the inner walls of both sides of the air duct. A connecting shaft is fixedly connected to the bottom of each pipe plug, and ear pieces are symmetrically fixedly connected to both sides of the lower end of the connecting shaft. A vertical shaft is fixedly installed inside the U-shaped part, and the vertical shaft passes through the ear piece. A spring is sleeved on the vertical shaft, and the ear piece is slidably connected to the vertical shaft. The upper and lower ends of the spring are respectively connected to the top inner wall of the U-shaped part and the top of the ear piece.
[0006] By adopting the above technical solution, the air pump delivers air to the air duct through the air inlet pipe and the air box. The air causes the pipe plug to drive the lug to squeeze the spring through the connecting shaft and push the pipe plug up. At this time, the air duct remains unobstructed, which can blow up the rubber molded product in the mold groove of the lower mold. This not only facilitates unloading, but also makes the rubber molded product less prone to deformation.
[0007] Optionally, a support frame is fixedly installed on the top of the operating table, and a hydraulic cylinder is fixedly installed on the top of the support frame. The output end of the hydraulic cylinder passes through the support frame and is fixedly installed on the top of the upper mold. Limiting components are symmetrically fixedly installed on both sides of the upper mold. A limiting shaft passes through and is slidably connected to the limiting component. The upper and lower ends of the limiting shaft are fixedly installed to the support frame and the operating table, respectively.
[0008] By adopting the above technical solution, the hydraulic cylinder can easily drive the upper mold to move vertically, thereby facilitating mold closing and opening. Furthermore, the limiting function between the limiting component and the limiting shaft ensures the accuracy of the position between the upper mold and the lower mold, preventing the upper mold and the lower mold from shifting after long-term use.
[0009] Optionally, each of the four corners of the bottom of the operating table is fixedly connected to a support leg. The bottom of the support leg is provided with a threaded hole, and a matching threaded shaft is threaded into the threaded hole. The lower end of the threaded shaft is fixedly connected to a mounting base.
[0010] By adopting the above technical solution, the position of the rotating threaded shaft inside the threaded hole is adjusted, thereby adjusting the height of each mounting base so that the device can remain level even on uneven ground.
[0011] Optionally, support rods are symmetrically fixedly installed on both sides of the lower mold, and the bottom of the support rods is fixedly installed to the top of the operating table.
[0012] By adopting the above technical solution, support points are provided for the lower mold.
[0013] Optionally, the mounting base has four mounting holes equidistantly spaced.
[0014] By adopting the above technical solution, it is easy to fix the mounting base on the ground, ensuring the stability of the device during use.
[0015] Optionally, a foot switch is provided below the control panel, which is used to control the operation of the hydraulic cylinder and the air pump.
[0016] By adopting the above technical solution, it is convenient to control the operation of hydraulic cylinders and air pumps.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0018] 1. The technical solution of this application uses the cooperation of an air pump, an air inlet pipe, a bellows, an air duct, a pipe plug, a connecting shaft, a U-shaped part, an ear part and a spring to blow up the rubber molded product in the mold groove of the lower mold, which facilitates unloading and makes the rubber molded product less prone to deformation.
[0019] 2. The technical solution of this application uses a hydraulic cylinder to easily drive the upper mold to move vertically, thereby facilitating mold closing and opening. The limiting function between the limiting component and the limiting shaft ensures the accuracy of the position between the upper mold and the lower mold and prevents the upper mold and the lower mold from shifting after long-term use.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Please see Figure 1-4This utility model provides a rubber hydraulic molding device, including an operating table 1. A bellows 2 is fixedly installed on the top of the operating table 1, and a lower mold 3 and an upper mold 4 are arranged above the operating table 1. An air pump 15 is fixedly installed at the bottom of the operating table 1, and an air inlet pipe 16 passes through the bottom of the operating table 1. The output end of the air pump 15 is connected to the lower end of the air inlet pipe 16, and the upper end of the air inlet pipe 16 is connected to the interior of the bellows 2. Several air ducts 5 pass through and connect to the top of the bellows 2, and the upper ends of the air ducts 5 pass through the bottom of the lower mold 3. The upper side of the inside of the duct 5 is provided with a matching pipe plug 19, and the inner walls of both sides of the duct 5 are symmetrically fixedly connected with U-shaped parts 20. The bottom of the pipe plug 19 is fixedly connected with a connecting shaft 21. The lower ends of the connecting shaft 21 are symmetrically fixedly connected with ear parts 24. A vertical shaft 22 is fixedly installed inside the U-shaped part 20. The vertical shaft 22 passes through the ear part 24, and a spring 23 is sleeved on the vertical shaft 22. The ear part 24 is slidably connected to the vertical shaft 22. The upper and lower ends of the spring 23 are respectively connected to the top inner wall of the U-shaped part 20 and the top of the ear part 24.
[0028] In this technical solution, air is delivered to the air duct 5 through the air inlet pipe 16 and the air box 2 by the air pump 15. The air causes the pipe plug 19 to drive the ear piece 24 to squeeze the spring 23 through the connecting shaft 21 and push the pipe plug 19 up. At this time, the air duct 5 remains unobstructed, which can blow up the rubber molded product in the mold groove of the lower mold 3. This facilitates unloading and makes the rubber molded product less prone to deformation.
[0029] In some technical solutions, such as Figure 1-2 As shown, a support frame 6 is fixedly installed on the top of the operating table 1, and a hydraulic cylinder 7 is fixedly installed on the top of the support frame 6. The output end of the hydraulic cylinder 7 passes through the support frame 6 and is fixedly installed on the top of the upper mold 4. Limiting components 11 are symmetrically fixedly installed on both sides of the upper mold 4. A limiting shaft 12 passes through and is slidably connected to the limiting component 11. The upper and lower ends of the limiting shaft 12 are fixedly installed on the support frame 6 and the operating table 1, respectively.
[0030] In use, the hydraulic cylinder 7 can easily drive the upper mold 4 to move vertically, thus facilitating mold closing and opening. The limiting effect between the limiting component 11 and the limiting shaft 12 ensures the accuracy of the position between the upper mold 4 and the lower mold 3, preventing the upper mold 4 and the lower mold 3 from shifting after long-term use.
[0031] In some technical solutions, such as Figure 1-2 As shown, support legs 8 are fixedly connected to the four corners of the bottom of the operating table 1. The bottom of the support legs 8 is provided with threaded holes 17. The threaded holes 17 are connected to matching threaded shafts 9. The lower end of the threaded shafts 9 is fixedly connected to mounting bases 10.
[0032] In use, the position of the threaded shaft 9 inside the threaded hole 17 is adjusted by rotating the threaded shaft 9, thereby adjusting the height of each mounting base 10 so that the device can remain level even on uneven ground.
[0033] In some technical solutions, such as Figure 1 As shown, support rods 13 are symmetrically fixedly installed on both sides of the lower mold 3, and the bottom of the support rods 13 is fixedly installed on the top of the operating table 1.
[0034] In use, the support rod 13 provides a support point for the lower mold 3.
[0035] In some technical solutions, such as Figure 2 As shown, the mounting base 10 has four mounting holes 18 at equal intervals.
[0036] When in use, the mounting base 10 can be easily fixed to the ground through the mounting hole 18, ensuring the stability of the device during use.
[0037] In some technical solutions, such as Figure 1 As shown, a foot switch 14 is provided below the control panel 1. The foot switch 14 is used to control the operation of the hydraulic cylinder 7 and the air pump 15.
[0038] In use, the foot switch 14 can be used to easily control the operation of the hydraulic cylinder 7 and the air pump 15.
[0039] Working principle: During use, the rubber raw material is placed on the lower mold 3. The hydraulic cylinder 7 drives the upper mold 4 to move down to close the mold and then moves the upper mold 4 up to open the mold. The limiting action between the limiting part 11 and the limiting shaft 12 ensures the accuracy of the position between the upper mold 4 and the lower mold 3. After the mold is opened, the air pump 15 delivers air to the air duct 5 through the air inlet pipe 16 and the air box 2. The air causes the pipe plug 19 to drive the ear piece 24 to squeeze the spring 23 through the connecting shaft 21 and push the pipe plug 19 up. At this time, the air duct 5 remains unobstructed, which can blow up the rubber molded product in the mold groove of the lower mold 3, which is convenient for unloading and prevents the rubber molded product from deforming.
