Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to a mold with a bottom drainage structure with a slider. Background Technology

[0002] In the metal die casting production process, in order to ensure smooth demolding of castings, protect the mold, and extend its service life, it is an essential step to spray a release agent on key parts such as the mold cavity, runner, and slide block before each injection. The release agent is usually in the form of a water-based emulsion, which is atomized by mixing with compressed air through spraying equipment and evenly covering the mold surface.

[0003] However, in practice, excess release agent and cooling water from the spraying process easily remain at the bottom of the mold slider. When the slider resets, the residue at the bottom is pushed into the mold cavity, where it encounters the high-temperature molten aluminum and creates pores, affecting the quality of the casting. Traditional compressed air purging is insufficient to effectively penetrate and remove the residual liquid at the bottom of the slider.

[0004] To address the aforementioned issues, existing technologies typically involve creating a drainage groove at the bottom of the slider and drilling holes in the bottom of the drainage groove to guide residual liquid to the ejector plate area for drainage. However, while this method can remove liquid accumulation at the bottom of the slider, it leads to contamination of the ejector plate area, increasing the workload for cleaning and maintenance. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and provide a mold with a bottom drainage structure for directly discharging accumulated liquid to the outside of the mold without contaminating the ejector plate area.

[0006] The objective of this application is achieved through the following technical solution: A mold with a bottom drainage structure for sliders includes: a mold frame, a mold core, and at least one slider. The mold core is embedded in the mold frame. At least one groove is provided on both sides of the mold frame. Each slider is slidably disposed in one of the grooves. The mold with the bottom drainage structure for sliders further includes at least one bottom drainage structure for sliders. Each of the slide grooves is provided with a slider bottom drainage structure at the bottom, and each slider bottom drainage structure has a first drainage groove and a second drainage groove that are connected to each other; The first drainage groove is located at one end of the corresponding slide near the mold core, and the extension direction of the first drainage groove is perpendicular to the movement direction of the slider; The second drainage groove is located on the side of the corresponding slide groove that is close to the ground. One end of the second drainage groove is connected to the end of the first drainage groove that is close to the ground. The other end of the second drainage groove extends to the outside of the mold frame. The extension direction of the second drainage groove forms an angle with the movement direction of the slider.

[0007] In one embodiment, the angle between the extension direction of the second drainage groove and the movement direction of the slider is greater than or equal to 5°.

[0008] In one embodiment, the width of both the first drainage channel and the width of the second drainage channel are greater than or equal to 20 mm.

[0009] In one embodiment, the depth of both the first drainage trough and the second drainage trough is greater than or equal to 15 mm.

[0010] In one embodiment, the first drainage channel has an opening on the side near the mold core.

[0011] In one embodiment, the sidewall and bottom of the first drainage trough are connected by a first arc surface, and the sidewall and bottom of the second drainage trough are connected by a second arc surface.

[0012] In one embodiment, the sidewall of the first drainage channel at the end away from the second drainage channel is connected to the sidewall of the first drainage channel at the end away from the mold core via a third arc surface.

[0013] In one embodiment, the sidewall of the first drainage channel and the sidewall of the second drainage channel are connected by a fourth arc surface.

[0014] In one embodiment, the second drainage groove is located between the mounting position of the wear-resistant block of the mold and the side wall of the chute.

[0015] In one embodiment, the bottom of the chute also has a drainage ramp, which is located at the end of the chute near the ground and is disposed between the second drainage trough and the side wall of the chute.

[0016] Compared with the prior art, this application has at least the following advantages: 1. The aforementioned mold with a slider bottom drainage structure features a slider bottom drainage structure at the bottom of the slide groove. By creating a first drainage groove perpendicular to the slider's movement direction at the end of the slide groove near the mold core, residual liquid or residue is prevented from being carried into the mold cavity during slider movement, thus ensuring product quality. Simultaneously, a second drainage groove extending to the outside of the mold and inclined to the slider's movement direction utilizes gravity to discharge residue and residual liquid to the outside of the mold with the slider bottom drainage structure, eliminating the need to discharge to the ejector plate area, preventing contamination of the ejector plate area, and reducing cleaning and maintenance difficulties.

[0017] 2. The mold with the bottom drainage structure of the slider has a simple structure. It does not require drilling to drain the sewage. It only needs to process the first drainage groove and the second drainage groove on the surface of the mold frame, which reduces the processing difficulty. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 This invention relates to a mold 10 with a bottom drainage structure for sliders, comprising: a mold frame 100, a mold core 200, at least one slider 300, and at least one bottom drainage structure 400 for sliders. The mold core 200 is embedded in the mold frame 100. At least one groove 101 is provided on both sides of the mold frame 100, and each slider 300 is slidably disposed in a groove 101. A bottom drainage structure 400 for sliders is provided at the bottom of each groove 101, and each bottom drainage structure 400 for sliders has a first drainage groove 410 and a second drainage groove 420 that are connected to each other. The first drainage groove 410 is located at one end of the corresponding groove 101 near the mold core 200 of the mold, and the extending direction of the first drainage groove 410 is perpendicular to the movement direction of the slider 300. The second drainage groove 420 is located on the side of the corresponding slide 101 near the ground. One end of the second drainage groove 420 is connected to the end of the first drainage groove 410 near the ground. The other end of the second drainage groove 420 extends to the outside of the mold frame 100. The extension direction of the second drainage groove 420 is at an angle to the movement direction of the slider 300.

[0024] In this embodiment, the mold 10 with a slider bottom drainage structure has a slider bottom drainage structure 400 at the bottom of the slide groove 101. By opening a first drainage groove 410 perpendicular to the movement direction of the slider 300 at one end of the slide groove 101 near the mold core 200, residual liquid or residue is prevented from being carried into the mold cavity when the slider 300 moves, thus ensuring product quality. At the same time, by extending to the outside of the mold and inclined to the movement direction of the slider 300, the residue and residual liquid are discharged to the outside of the mold 10 with the slider bottom drainage structure by gravity, without needing to be discharged to the ejector plate area, thus avoiding contamination of the ejector plate area and reducing cleaning and maintenance difficulty. Furthermore, the slider bottom drainage structure 400 has a simple structure, does not require drilling for drainage, and only requires machining the grooves of the first drainage groove 410 and the second drainage groove 420 on the surface of the mold frame 100, reducing the machining difficulty.

[0025] Specifically, in this embodiment, the mold 10 with a bottom drainage structure for sliders has two grooves 101 and two sliders 300. The two grooves 101 are located on both sides of the mold 10 with the bottom drainage structure for sliders, and the two sliders 300 correspond one-to-one with the two grooves 101. Each groove 101 has a bottom drainage structure 400 for sliders.

[0026] like Figure 3As shown, in one embodiment, the angle between the extending direction of the second drainage channel 420 and the moving direction of the slider 300 is greater than or equal to 5°. During use, the slider 300 moves parallel to the ground, meaning the second drainage channel 420 is inclined towards the ground. Increasing the slope of the second drainage channel directly increases the water flow velocity, thereby flushing residue out of the second drainage channel 420, preventing blockage, and ensuring that residual liquid and residue in the second drainage channel 420 are discharged along the inclined second drainage channel 420 to the outside of the mold 10 with the bottom drainage structure of the slider. Specifically, in this embodiment, the angle between the extending direction of the second drainage channel 420 and the moving direction of the slider 300 is 5°.

[0027] like Figure 3 As shown, in one embodiment, the width of the first drainage channel 410 and the width of the second drainage channel 420 are both greater than or equal to 20 mm. It can be understood that by increasing the width of the first drainage channel 410 and the second drainage channel 420, blockages caused by residue retention are avoided, ensuring smooth drainage and slag removal from the first drainage channel 410 and the second drainage channel 420, and improving the reliability of the bottom drainage structure 400 of the slider.

[0028] like Figure 3 As shown, in one embodiment, the depth of both the first drainage channel 410 and the second drainage channel 420 is greater than or equal to 15 mm. It is understood that by increasing the depth of the first drainage channel 410 and the second drainage channel 420, an ideal flow rate and capacity are provided for the bottom drainage structure 400 of the slider, reducing the difficulty of cleaning.

[0029] Specifically, in this embodiment, the depth of the first drainage channel 410 and the depth of the second drainage channel 420 are both 20mm, and the width of the first drainage channel 410 and the width of the second drainage channel 420 are both 15mm, which improves the reliability of anti-clogging while ensuring drainage.

[0030] like Figures 2 to 4 As shown, in one embodiment, the first drainage groove 410 has an opening 411 on the side near the mold core 200. The sidewall portion of the mold core 200 facing the slide 101 serves as the sidewall of the first drainage groove 410. The first drainage groove 410 is located at the end of the slide 101 and has no groove wall, thus preventing the formation of residual liquid or residue on the side of the slide 101 near the mold core 200. This prevents residual liquid or residue from being carried into the mold cavity when the slider 300 moves, thereby ensuring product quality. At the same time, the open structure simplifies the processing technology.

[0031] like Figure 4As shown, in one embodiment, the sidewall and bottom of the first drainage groove 410 are connected by a first arc surface 412, and the sidewall and bottom of the second drainage groove 420 are connected by a second arc surface 421. It is understood that the transition through the first arc surface 412 and the second arc surface 421 eliminates the sharp corners at the bottom of the first drainage groove 410 and the second drainage groove 420, avoiding stress concentration and extending the service life of the mold 10 with the slider bottom drainage structure. Furthermore, the arc corners facilitate the smooth passage of residual liquid and residue, reducing resistance and wear, and preventing residue or liquid from accumulating in the sharp corners at the bottom of the first drainage groove 410 and the second drainage groove 420, facilitating cleaning and maintenance. Simultaneously, the arc transition surfaces facilitate processing and improve processing efficiency.

[0032] like Figure 4 As shown, in one embodiment, the sidewall of the first drainage groove 410 away from the second drainage groove 420 and the sidewall of the first drainage groove 410 away from the mold core 200 are transitionally connected by a third arc surface 413. The two sidewalls are transitionally connected by setting the third arc surface 413 at the corner position of the first drainage groove 410 away from the second drainage groove 420. This eliminates sharp corners, simplifies processing, avoids stress concentration, and extends the service life of the mold 10 with the slider bottom drainage structure.

[0033] As shown in the figure, in one embodiment, the first drainage groove 410 is transitionally connected to the side wall of the second drainage groove 420 via a fourth arc surface 422. The fourth arc surface 422 is provided at the intersection of the side walls of the first drainage groove 410 and the second drainage groove 420 to disperse stress at the connection point and extend the service life of the mold 10 with the slider bottom drainage structure. Simultaneously, the arc surface is easy to process and shape, reducing processing difficulty.

[0034] like Figure 3 As shown, in one embodiment, the second drainage groove 420 is located between the mounting position of the wear-resistant block (not shown) of the mold 10 with the slider bottom drainage structure and the side wall of the slide 101. It is understood that the second drainage groove 420 communicates with the first drainage groove 410 between the wear-resistant block and the side wall of the slide 101, preventing the second drainage groove 420 from disrupting the mounting position of the wear-resistant block and affecting its stability. Simultaneously, it prevents the second drainage groove 420 from extending obliquely to the side wall of the slide 101 and then from inside the side wall of the slide 101 to the outside of the mold, thereby ensuring the structural strength of the slide 101 and reducing processing difficulty.

[0035] like Figure 3As shown, in one embodiment, the bottom of the chute 101 also has a drainage slope 1011, which is located at the end of the chute 101 near the ground and is disposed between the second drainage channel 420 and the side wall of the chute 101. A clearance area (not shown) is formed between the two sides of the chute 101 and the slider 300. In actual use, the clearance area near the ground of the mold 10 with the slider bottom drainage structure is prone to water accumulation. By providing a drainage slope 1011 inclined towards the thickness direction of the mold 10 at the bottom of the chute 101 near the ground, the water accumulated in the clearance area can be discharged along the drainage slope 1011 to the outside of the mold 10 with the slider bottom drainage structure, preventing residual liquid or residue from accumulating in the clearance area.

[0036] Compared with the prior art, this application has at least the following advantages: 1. The aforementioned mold with a slider bottom drainage structure features a slider bottom drainage structure at the bottom of the slide groove. By creating a first drainage groove perpendicular to the slider's movement direction at the end of the slide groove near the mold core, residual liquid or residue is prevented from being carried into the mold cavity during slider movement, thus ensuring product quality. Simultaneously, a second drainage groove extending to the outside of the mold and inclined to the slider's movement direction utilizes gravity to discharge residue and residual liquid to the outside of the mold with the slider bottom drainage structure, eliminating the need to discharge to the ejector plate area, preventing contamination of the ejector plate area, and reducing cleaning and maintenance difficulties.

[0037] 2. The mold with the bottom drainage structure of the slider has a simple structure. It does not require drilling to drain the sewage. It only needs to process the first drainage groove and the second drainage groove on the surface of the mold frame, which reduces the processing difficulty.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
