Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a slide seat and mold with an oil guide groove structure. Background Technology

[0002] Currently, in commonly used molds, mold structures with relative movement are set on the mold for the needs of product molding or demolding, such as slide seats and lower mold plates. When the mold is closed or opened, the slide seats slide on the lower mold plate to realize product molding and demolding.

[0003] In the existing technology, since the slide seat slides relative to the lower template, there will be friction due to the relative movement. The slide seat is generally recessed with an oil guide groove, which contains lubricating oil. The oil guide groove serves to lubricate the slide seat and the lower template, thereby reducing the friction between the slide seat and the lower template and avoiding the phenomenon of "iron powder scraping" caused by excessive wear between the slide seat and the lower template. This extends the service life of the mold and reduces production and maintenance costs.

[0004] However, the current oil guide groove structure on the slide seat is relatively simple, generally wavy, and its oil guiding effect is generally poor. Sometimes uneven lubrication will occur, resulting in poor lubrication effect. Long-term operation of the mold may even cause wear of the slide seat and lower platen, or even cause the slide seat to jam, reducing the service life of the mold and affecting production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a slide seat and mold with an oil guide groove structure, which aims to solve or at least partially solve the shortcomings of the above-mentioned background technology. It can improve the lubrication effect between the slide seat and the lower mold plate, thereby preventing mold wear and extending the service life of the mold.

[0006] This utility model provides a sliding seat with an oil guide groove structure. The sliding seat is disposed on a lower template and can slide back and forth on the lower template in the front-to-back direction. The sliding seat has multiple oil guide groove structures recessed on the contact surface that contacts the lower template. The oil guide groove structures are used to contain lubricating oil. Each oil guide groove structure has a first oil guide groove and two second oil guide grooves that are connected to the first oil guide groove. The multiple first oil guide grooves are distributed in parallel on the contact surface. The first oil guide grooves are straight and extend in the front-to-back direction. The second oil guide grooves are wavy, and the two second oil guide grooves are mirror images of the first oil guide grooves that are connected to them. The second oil guide grooves have a crest end and a trough end. The crest end is disposed away from the first oil guide groove, and the trough end is connected to the first oil guide groove.

[0007] Furthermore, the second oil guide groove is in the form of a curved wave shape or a broken line wave shape.

[0008] Furthermore, the distance L1 between the two wave crests that are mirror-symmetric is equal to the distance L2 between the two adjacent wave troughs.

[0009] Furthermore, a buffer groove is recessed at the junction of the first oil guide groove and the trough end to prevent excessive lubricating oil from overflowing at the junction.

[0010] Furthermore, a first chamfer structure is provided at the connection between the second oil guide groove and the contact surface.

[0011] Furthermore, the first chamfer structure is a rounded corner, and the radius R1 of the rounded corner is 0.25mm-0.50mm.

[0012] Furthermore, a second chamfer structure is provided at the connection between the bottom wall and the side wall of the second oil guide groove.

[0013] Furthermore, the second chamfer structure is a rounded corner, and the radius R2 of the rounded corner is 0.50mm-0.70mm.

[0014] Furthermore, the depth of the first oil guide groove is the same as the depth of the second oil guide groove.

[0015] This utility model also provides a mold, including an upper template, a lower template, and a sliding seat with an oil guide groove structure, wherein the upper template, the lower template, and the sliding seat together form a molding cavity for molding products.

[0016] The sliding seat with an oil guide groove structure provided by this utility model can guide a portion of the lubricating oil to flow in the front-back direction during the sliding process of the sliding seat through the cooperation of the first oil guide groove and the second oil guide groove, thereby meeting the lubrication requirements of the contact surface in the front-back direction. It can also distribute and guide another portion of the lubricating oil away from the first oil guide groove in the left-right direction and diffuse it, thereby meeting the lubrication requirements of the contact surface in the left-right direction. This achieves uniform lubrication of the contact surface, thereby improving the lubrication effect and playing a role in preventing mold wear and extending the service life of the mold.

[0027] Please see Figure 1 , Figure 2 and Figure 5 A sliding seat with an oil guide groove structure, the sliding seat 10 is disposed on the lower template 20 and can slide back and forth on the lower template 20 in the front-back direction.

[0028] The slide seat 10 has multiple oil guide groove structures recessed on the contact surface 11 that contacts the lower template 20. The oil guide groove structures are used to contain lubricating oil. Each oil guide groove structure has a first oil guide groove 12 and two second oil guide grooves 13 that are connected to the first oil guide groove 12. The multiple first oil guide grooves 12 are distributed in parallel on the contact surface 11. The first oil guide grooves 12 are straight and extend in the front-back direction. The second oil guide grooves 13 are wavy, and the two second oil guide grooves 13 are mirror images of the first oil guide grooves 12 that are connected to them. The second oil guide grooves 13 have a crest end 131 and a trough end 132. The crest end 131 is located away from the first oil guide groove 12, and the trough end 132 is connected to the first oil guide groove 12.

[0029] As described above, the sliding seat with an oil guide groove structure provided in this embodiment of the present invention, through the cooperation of the first oil guide groove 12 and the second oil guide groove 13, can guide a portion of the lubricating oil to flow in the front-back direction during the sliding process of the sliding seat 10, thereby satisfying the lubrication requirements of the contact surface 11 in the front-back direction. It can also distribute and guide another portion of the lubricating oil away from the first oil guide groove 12 in the left-right direction and diffuse it, thereby satisfying the lubrication requirements of the contact surface 11 in the left-right direction. This achieves uniform lubrication of the contact surface 11, increases the lubrication area, thereby improving the lubrication effect and playing a role in preventing mold wear and extending the service life of the mold.

[0030] The second oil guide groove 13 is wavy and is located on the left and right sides of the first oil guide groove 12. It can guide the lubricating oil to flow not only in the front-back direction, but also in the left-right direction, so that the lubrication effect is more uniform.

[0031] Furthermore, please refer to Figure 2 The second oil guide groove 13 can be in a curved, wavy shape; please refer to [link / reference]. Figure 3 The second oil guide groove 13 can also be in the shape of a zigzag wave. In this embodiment, the second oil guide groove 13 is in the shape of a curved wave. This design allows the lubricating oil on the second oil guide groove 13 to flow more smoothly, further improving the lubrication effect.

[0032] Please see Figure 4 The distance L1 between the two mirror-symmetrical peaks 131 is equal to the distance L2 between the two adjacent troughs 132. This arrangement allows the second oil guide groove 13 to guide the lubricating oil away from the first oil guide groove 12 in the left-right direction and diffuse it, while also ensuring the smooth flow of the lubricating oil in the second oil guide groove 13.

[0033] Please see Figure 2 and Figure 7 During the sliding process of the slide seat 10, the lubricating oil on the first oil guide groove 12 and the second oil guide groove 13 will flow through the intersection. A buffer groove 121 is recessed at the intersection of the first oil guide groove 12 and the trough end 132. The buffer groove 121 is used to prevent excessive lubricating oil from overflowing at the intersection, so as to avoid the lubricating oil overflowing onto the mold surface and affecting the normal operation of the mold.

[0034] Please see Figure 6 A first chamfer structure 133 is provided at the connection between the second oil guide groove 13 and the contact surface 11. The first chamfer structure 133 can increase the contact area between the lubricating oil on the second oil guide groove 13 and the lower template 20. At the same time, by utilizing the surface tension and adhesion of the lubricating oil, the lubricating oil can be better diffused in the left and right directions, further improving the lubrication area in the left and right directions, thereby providing a lubrication effect.

[0035] The first chamfer structure 133 can be either a bevel or a rounded corner; in this embodiment, the first chamfer structure 133 is a rounded corner, and the radius R1 of this rounded corner is 0.25mm-0.50mm. If the radius R1 is too large, more lubricating oil needs to be added, increasing production and maintenance costs; if the radius R1 is too small, the diffusion effect of the lubricating oil is generally poor. After multiple tests, a radius R1 in the range of 0.20mm-0.60mm can meet the requirements of both production and maintenance costs and diffusion effect. Preferably, the radius R1 is 0.25mm-0.50mm. Those skilled in the art can specifically set the radius R1 to 0.25mm, 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm, etc., and no unique limitation is made here.

[0036] Please see Figure 6 A second chamfer structure 134 is provided at the connection between the bottom wall and the side wall of the second oil guide groove 13. The second chamfer structure 134 enables the lubricating oil to flow more smoothly in the second oil guide groove 13, thereby ensuring the lubrication effect.

[0037] In this embodiment, the second chamfer structure 134 is a rounded corner, and the radius R2 of this rounded corner is 0.50mm-0.70mm. If the radius R2 is too large, the volume of the second oil guide groove 13 will decrease, resulting in less lubricating oil flow and weakening the lubrication effect; if the radius R2 is too small, the improvement in the smoothness of lubricating oil flow will not be significant. After multiple tests, a radius R2 in the range of 0.45mm-0.80mm can meet the requirements of both lubricating oil flow and smoothness. Preferably, the radius R2 is 0.50mm-0.70mm. Those skilled in the art can specifically set the radius R2 to 0.50mm, 0.55mm, 0.60mm, 0.65mm, 0.70mm, etc., and no unique limitation is made here.

[0038] Please see Figure 5 and Figure 6 The depth of the first oil guide groove 12 is the same as the depth of the second oil guide groove 13. This setting allows the lubricating oil to flow smoothly between the first oil guide groove 12 and the second oil guide groove 13, thereby ensuring the lubrication effect.

[0039] The advantages of the sliding seat with oil guide groove structure provided by this utility model include: it can provide lubrication between itself and the lower template 20, thereby preventing mold wear and extending the service life of the mold.

[0040] In addition, this utility model also provides a mold, including an upper template, a lower template 20 and the above-mentioned sliding seat with an oil guide groove structure. The upper template, the lower template 20 and the sliding seat 10 together enclose a molding cavity for molding products.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
