Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic product production, in particular to a wear-resistant rubber and plastic base mould. Background Art

[0002] With the continuous development of industrial technology, the demand for wear-resistant rubber and plastic bases, as important components in mechanical equipment, is increasing. Wear-resistant rubber and plastic bases are not only required to have excellent wear resistance, but also good dimensional stability and processing accuracy. Therefore, the technical level of the wear-resistant rubber and plastic base mold is directly related to the quality and production efficiency of the product. However, the existing wear-resistant rubber and plastic base mold technology still has some problems that need to be solved, such as poor cooling effect, low production efficiency, and complex mold structure. These problems limit the further development of wear-resistant rubber and plastic base molds. Some molds rely solely on natural heat dissipation, which causes the mold temperature to rise rapidly during the production process, which not only affects the molding accuracy of the product and causes deviations in the size of the wear-resistant rubber and plastic base, but also extends the production cycle of a single product and reduces overall production efficiency. Utility Model Content

[0008] Preferably, the upper mold base is provided with injection holes having the same number as the mold grooves and corresponding positions.

[0014] Compared with the existing technology, the beneficial effects of the present invention are:

[0015] 1. In this wear-resistant rubber and plastic base mold, a number of evenly and equidistantly arranged mold grooves are opened on the lower mold base, so that multiple wear-resistant rubber and plastic bases can be produced at the same time; by the synchronously working lifting cylinders embedded in the four top corners of the lower mold base and the arrangement of their piston rods connected to the four top corners of the upper mold base, the upper mold base can cooperate with the lower mold base to complete the mold closing and opening actions under the drive of the lifting cylinders; by the hollow cooling cavity opened inside the lower mold base and the hydraulic pump installed at the bottom of the cooling liquid tank, the hydraulic pump outlet is connected to one end of the hollow cooling cavity through the liquid inlet pipe and the other end of the hollow cooling cavity is connected to the inside of the cooling liquid tank through the return pipe, so that the coolant can circulate in the hollow cooling cavity, thereby effectively taking away the heat generated by the mold during the production process and ensuring the normal progress of production.

[0016] 2. In this wear-resistant rubber and plastic base mold, two sets of synchronously working ejector cylinders are installed on both sides of the top surface of the base. The two sets of ejector cylinders are symmetrically arranged at both ends of the coolant tank, so that the mold can smoothly eject the formed wear-resistant rubber and plastic base after the mold is opened, thereby improving production efficiency.

[0017] 3. In this wear-resistant rubber and plastic base mold, the top surface of the movable plate is installed with ejector rods with the same number and corresponding positions as the mold grooves.

A base 30 is provided directly below the lower mold base 10, and a cooling liquid tank 40 for containing coolant is installed on the base 30; a number of mold grooves 11 are arranged evenly and equidistantly on the lower mold base 10, and synchronously working lifting cylinders 12 are embedded at the four top corners of the lower mold base 10. The piston rods 13 of the four groups of lifting cylinders 12 are connected to the four top corners of the upper mold base 20, and a hollow cooling cavity 14 is provided inside the lower mold base 10; a hydraulic pump 41 is installed at the bottom of the cooling liquid tank 40, and the outlet of the hydraulic pump 41 is connected to one end of the hollow cooling cavity 14 through a liquid inlet pipe 42, and the other end of the hollow cooling cavity 14 is connected to the inside of the cooling liquid tank 40 through a return pipe 43. The cooling liquid tank 40 for containing coolant installed on the base 30 can provide cooling liquid for mold cooling. ; By opening a number of evenly and equidistantly arranged mold grooves 11 on the lower mold base 10, multiple wear-resistant rubber and plastic bases can be produced at the same time; by the synchronously working lifting cylinders 12 embedded at the four top corners of the lower mold base 10 and the arrangement of their piston rods 13 connected to the four top corners of the upper mold base 20, the upper mold base 20 can cooperate with the lower mold base 10 to complete the mold closing and opening actions under the drive of the lifting cylinder 12; by the hollow cooling cavity 14 opened inside the lower mold base 10 and the hydraulic pump 41 installed at the bottom of the cooling liquid tank 40, the outlet of the hydraulic pump 41 is connected to one end of the hollow cooling cavity 14 through the liquid inlet pipe 42 and the other end of the hollow cooling cavity 14 is connected to the inside of the cooling liquid tank 40 through the return pipe 43, the coolant can circulate in the hollow cooling cavity 14, thereby effectively taking away the heat generated by the mold during the production process and ensuring the normal progress of production.

[0029] Furthermore, the upper mold base 20 is provided with injection holes 21 having the same number and corresponding positions as the mold grooves 11, so that the injection molding process is more accurate and efficient, and the molding quality of the wear-resistant rubber-plastic base is ensured.

[0030] Specifically, two sets of synchronously working ejection cylinders 31 are installed on both sides of the top surface of the base 30. The two sets of ejection cylinders 31 are symmetrically arranged at both ends of the coolant tank 40, so that the mold can smoothly eject the molded wear-resistant rubber and plastic base after the mold is opened, thereby improving production efficiency.

[0031] Among them, the ejection piston rod of the ejection cylinder 31 is connected to a movable plate 32 with adjustable height, which makes the ejection process more flexible, can adapt to wear-resistant rubber and plastic bases of different heights, and enhances the versatility of the mold.

[0033] The working principle of this wear-resistant rubber and plastic base mold:

[0034] First, place the mold in the appropriate position and ensure that the base 30 is placed stably. Next, check whether there is enough coolant in the coolant tank 40. If not, add coolant to the appropriate level.

[0035] Then, the hydraulic pump 41 is started, and the hydraulic pump 41 delivers the coolant in the coolant tank 40 to the hollow cooling cavity 14 inside the lower die base 10 through the liquid inlet pipe 42, so that the coolant circulates in the hollow cooling cavity 14, thereby cooling the lower die base 10 in advance;

[0036] After that, the wear-resistant rubber and plastic raw materials are placed into the die groove 11 of the lower die base 10; then the four sets of lifting cylinders 12 are started, and the piston rods 13 of the lifting cylinders 12 drive the upper die base 20 to move downward, closing the mold with the lower die base 10, and forming the raw materials in the die groove 11;

[0037] After the processing is completed, the lifting cylinder 12 drives the upper mold base 20 to rise and open the mold; finally, the hydraulic pump 41 is turned off, and the coolant flows back to the coolant tank 40 through the return pipe 43, completing the production process of the wear-resistant rubber and plastic base. The above steps can be repeated for subsequent production.
