[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0033] Please see Figure 1 and Figure 2 This utility model embodiment provides a plastic mold maintenance structure for maintaining a plastic mold 5, including:
[0034] The machine casing 1 has multiple horizontally arranged bearing rollers 11 inside, which are used to support the plastic mold 5;
[0035] The maintenance component 2 is used to apply anti-rust oil to the surface of the plastic mold 5. The maintenance component 2 includes two rows of sponge rollers 21 arranged symmetrically and in parallel. The sponge rollers 21 are rotatably mounted in the housing 1 through corresponding oil injection shafts 22. The outer part of the oil injection shaft 22 located inside the sponge rollers 21 is fixedly provided with multiple oil injection holes 221. One end of the oil injection shaft 22 movably passes through the housing 1 and extends to the outside of the housing 1 and is rotatably connected to the connecting seat 23. The connecting seat 23 is connected to the external oil supply equipment through the oil supply pipe 24.
[0036] The cleaning component 3 is fixedly installed inside the chassis 1 and located on one side of the maintenance component 2, and is used to clean the surface of the plastic mold 5.
[0037] In practical application, the plastic mold 5 is placed on the support roller 11, and rust-preventive oil is introduced into the oil injection shaft 22 through the oil supply pipe 24. The rust-preventive oil penetrates through the oil injection hole 221 and is absorbed by the sponge roller 21, pushing the plastic mold 5 so that it moves horizontally on the support roller 11. When it passes through the cleaning component 3, the surface of the plastic mold 5 is cleaned by the cleaning component 3. When the plastic mold 5 moves between the two sets of horizontally arranged sponge rollers 21, the rust-preventive oil in the sponge rollers 21 is squeezed out by the plastic mold 5 and applied to the plastic mold 5, thereby achieving the maintenance of the plastic mold 5.
[0038] In this embodiment, the rust-preventive oil stored inside the sponge rollers 21 is evenly extruded onto the surface of the plastic mold 5 by the extrusion of two sets of symmetrically parallel sponge rollers 21. This achieves the maintenance of the plastic mold 5. Based on the adsorption and flexibility of the sponge rollers 21, they can adapt to the uneven surface of the plastic mold 5. While ensuring that the rust-preventive oil evenly covers the surface of the plastic mold 5, the amount of oil output is controlled by the extrusion of the sponge rollers 21 by the plastic mold 5, effectively avoiding the problems of oil splashing and excessive loss that exist in traditional spraying processes.
[0039] Please see Figure 2 In a preferred embodiment of the present invention, an oil collection tank 12 is fixedly provided at the bottom of the chassis 1. The oil collection tank 12 is used to collect dripping rust-preventive oil. An oil drain port 13 is fixedly provided on the outside of the chassis 1 at the position corresponding to the lowest end of the oil collection tank 12.
[0040] In practical applications, this embodiment uses an oil collection tank 12 in conjunction with an oil drain port 13 to collect the dripping rust-preventive oil and then discharge it through the oil drain port 13 for recycling, effectively reducing the waste of rust-preventive liquid.
[0041] Please see Figure 1 In another preferred embodiment of the present invention, the cleaning component 3 is configured to be at least one, and the cleaning component 3 includes:
[0042] The gas transmission pipe 31 has one end fixedly installed on the inner wall of the housing 1, and the other end of the gas transmission pipe 31 passes through the housing 1 and extends to the outside to connect with the gas transmission equipment.
[0043] Multiple air nozzles 32 are fixedly installed at equal intervals on the air supply pipe 31 for cleaning the plastic mold 5 by air jetting.
[0044] In practical application, this embodiment uses an external air supply device to input compressed air into the air supply pipe 31, and sprays it out through the air jet 32 to wash the surface of the plastic mold 5, removing the adhering fine particulate impurities and improving the cleanliness of the surface of the plastic mold 5, thereby further enhancing the maintenance effect in conjunction with the sponge roller 21.
[0045] In one embodiment, the cleaning method of the cleaning component 3 can be set to various forms, such as brushing or rinsing with water, as long as it can clean the plastic mold 5. This embodiment does not impose any additional limitations here.
[0046] Please see Figure 1 In another preferred embodiment of this utility model, the sponge roller 21 and the air conveying pipe 31 are both parallel to the axis of the bearing roller 11.
[0047] In practical applications, this embodiment utilizes the parallel arrangement of the bearing roller 11, sponge roller 21, and air supply pipe 31 to facilitate the movement of the plastic mold 5, thereby ensuring the normal progress of the maintenance work.
[0048] Please see Figure 1 In another preferred embodiment of this utility model, the chassis 1 further includes a positioning component 4 for positioning, the positioning component 4 comprising:
[0049] The positioning seat 41 has a handle 411 fixedly installed on its side. The inner side of the chassis 1 is fixedly provided with a sliding groove 14. The positioning seat 41 slides with the sliding groove 14 through a slider 42.
[0050] The clamping unit 43 is fixedly mounted on the positioning seat 41 and is used to fix the side of the plastic mold 5.
[0051] The positioning unit 44 is fixedly mounted on the positioning seat 41 and is used to further fix the side of the plastic mold 5 in conjunction with the clamping unit 43. The positioning unit 44 includes two symmetrically arranged adjusting bolts 441. Both adjusting bolts 441 are threadedly engaged with the positioning seat 41. The ends of the adjusting bolts 441 movably pass through the positioning seat 41 and extend to the inner side of the positioning seat 41 to be movably connected with the extrusion head 442. A reserved groove 15 is also fixedly opened on the side wall of the machine housing 1 at the position corresponding to the adjusting bolts 441.
[0052] Furthermore, the clamping unit 43 includes:
[0053] Two clamps 431, the middle of which are connected to the inner side of the positioning seat 41 through a mounting seat 432 that is movably hinged, and one end of each of the two clamps 431 is connected to the connecting block 434 through a connecting rod 433. The two ends of the connecting rod 433 are movably hinged to the ends of the clamps 431 and the connecting block 434, respectively.
[0054] The second adjusting bolt 435 has its end movably locked in the connecting block 434. The second adjusting bolt 435 is also threadedly engaged with the positioning seat 41. The second adjusting bolt 435 movably passes through the positioning seat 41 and extends to the outside of the positioning seat 41.
[0055] In practical application, this embodiment uses clamping unit 43 in conjunction with positioning unit 44 to clamp and fix the plastic mold 5, achieving a positioning effect. Based on the sliding engagement of slide groove 14 and slider 42, positioning seat 41 can move horizontally within the housing 1, thereby moving the plastic mold 5 to cooperate with sponge roller 21 to complete the curing of the plastic mold 5. The positioning of the plastic mold 5 by the positioning component 4 avoids affecting the uniformity of the anti-rust oil coating due to differences in the amount of pressure exerted on the sponge rollers 21 on both sides of the plastic mold 5.
