Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-7 This utility model discloses a high-precision molding machine with real-time adjustable molding pressure, including a frame 1 and a housing 2 mounted on the frame 1, and also including a molding pressure adjustment component 3, a rapid cooling component 4, an upper mold component 5, and a lower mold component 6, wherein:

[0025] The housing 2 includes a hydraulic tank 21, a water tank 22, and a control box 23;

[0026] Please refer to the appendix. Figure 3 The molding adjustment component 3 includes a solenoid valve 31, which is electrically connected to a manual pressure regulator 32 and a control box 23. The solenoid valve 31 is connected to a cylinder 33 via an oil pipe. The cylinder 33 is welded to the bottom of a bearing plate 61 via a hydraulic shaft. The bearing plate 61 is welded to the bottom of a lower mold back plate 62 via several steel columns.

[0027] Please refer to the appendix. Figure 4 A sleeve 34 is fixed to one side of the lower mold back plate 62 by screws. A pressure sensor 35 is provided directly above the sleeve 34. The pressure sensor 35 is fixed to one side of the upper mold back plate 51 by screws. The rapid cooling component 4 includes several heat dissipation columns 41. The heat dissipation columns 41 are welded to the top surface of the heat dissipation plate 42. The bottom surface of the heat dissipation plate 42 abuts against the heat dissipation pipe 43. A cooling fan 44 is provided below the heat dissipation pipe 43.

[0028] The two ends of the heat dissipation pipe 43 are connected to the water tank 45 and the water pump 46 through water pipes. The water pump 46 is connected to the water tank 45. The top of the heat dissipation column 41 abuts against the bottom of the lower mold 63. Specifically, the water pump 46 makes the cold water in the water tank 45 continuously circulate in the heat dissipation pipe 43 to exchange heat with the heat conducted down from the heat dissipation column 41.

[0029] In this embodiment, during molding, the pressure sensor 35 is inserted into the sleeve 34 and subjected to a reaction force, thereby measuring the real-time molding pressure. The pressure sensor 35 feeds back the pressure signal to the control box 23 and displays it in real time through the pressure gauge 36. The control box 23 can compare the feedback value with the preset pressure data, and then control the solenoid valve 31 to make the cylinder 33 move, so that the pressure is always maintained within the preset standard pressure range, thereby improving the molding quality. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 5 as well as Figure 6 The control box 23 is electrically connected to the pressure gauge 36 installed on one side. A contact plate 341 is fitted inside the sleeve 34. The bottom of the contact plate 341 is welded to the sleeve 34 via a spring 342. Specifically, the bottom end of the pressure sensor 35 presses against the contact plate 341 and compresses the spring 342. The compression spring 342 gives the pressure sensor 35 a reaction force.

[0031] The lower mold 63 is provided with a lower mold groove 631, and the lower mold groove 631 is provided with an anti-slip pad 7. The lower mold 63 is fixed to the top surface of the lower mold back plate 62 by screws.

[0032] The lower mold back plate 62 has a hollow design inside and is fitted with a heat sink 42 and a heat sink pipe 43. The heat sink fan 44 is welded to the top of the support plate 61. The heat sink pipe 43 and the heat sink fan 44 are directly provided with a grid-shaped air vent 621. Specifically, the heat sink fan 44 blows air from the grid-shaped air vent 621 to the heat sink pipe 43 and the heat sink 42 to accelerate air circulation and thus accelerate heat dissipation, so that the water heated in the heat sink pipe 43 can be cooled down so that it can continuously absorb heat.

[0033] The frame 1 includes a base 11, and the oil cylinder 33 is nested inside the base 11. A fixing plate 12 is welded to the outside of the base 11. Limiting posts 13 are fastened to the four corners of the fixing plate 12 by screws. The limiting posts 13 pass through the four corners of the lower mold back plate 62 and slide together.

[0034] The upper mold back plate 51 is fixed to the top of the limiting post 13 by bolts, and the upper mold 52 is fixed to the bottom surface of the upper mold back plate 51 by screws. The upper mold 52 and the lower mold 63 are arranged symmetrically.

[0035] In this embodiment, the hydraulic cylinder 33 drives the bearing plate 61 to rise, which in turn drives the lower mold 63 on the lower mold back plate 62 to rise continuously until the upper mold 52 is fitted into the lower mold groove 631 to hot press and shape the rubber material. The lower mold back plate 62 rises and falls under the limit of the limiting post 13 to ensure that the molding track will not deviate and the molding accuracy is higher.

[0036] The working principle and usage process of this utility model are as follows: First, start the equipment and set the molding temperature, molding pressure and molding time through the control box 23. The upper mold back plate 51 preheats the upper mold 52 by electric heating. Then, weigh an appropriate weight of rubber raw material and pour it into the lower mold groove 631. Start the oil cylinder 33 to drive the bearing plate 61 to rise, which in turn drives the lower mold 63 on the lower mold back plate 62 to rise continuously until the upper mold 52 is fitted into the lower mold groove 631, and the rubber raw material is hot-pressed and shaped.

[0037] When the upper mold back plate 51 and the lower mold back plate 62 abut, the pressure sensor 35 on the upper mold back plate 51 is simultaneously inserted into the sleeve 34 on the lower mold back plate 62. The bottom end of the pressure sensor 35 presses against the contact plate 341 and compresses the spring 342. The compression spring 342 gives the pressure sensor 35 a reaction force, thereby measuring the real-time pressure of the molding. The pressure sensor 35 feeds back the pressure signal to the control box 23 and displays it in real time through the pressure gauge 36. The control box 23 compares the feedback value with the preset pressure data, and then controls the solenoid valve 31 to make the cylinder 33 move, so that the pressure is always maintained within the preset standard pressure range, thereby improving the molding quality. At the same time, when the automatic control molding fails, the molding pressure can be adjusted by the manual pressure regulator 32.

[0038] After a certain period of molding, the raw material is formed into the anti-slip mat finished product 7. The hydraulic cylinder 33 is activated to separate the upper and lower molds. At this time, the control box 23 controls the cooling fan 44 and the water pump 46 to work. The water pump 46 draws water from the water tank 45 into the cooling pipe 43 and forms a circulation. At this time, the heat of the anti-slip mat finished product 7 is quickly conducted to the cooling plate 42 through the cooling column 41 on the bottom surface of the lower mold 63 for heat dissipation, which increases the heat dissipation area. At the same time, it exchanges heat with the contacting cooling pipe 43. The cold water in the cooling pipe 43 quickly carries away the heat and accelerates the heat dissipation. Meanwhile, the cooling fan 44 below accelerates the air circulation and further improves the heat dissipation efficiency, so that the anti-slip mat finished product 7 can be quickly cooled and removed, which greatly improves the molding efficiency.
