Description

Technical Field

[0001] This utility model relates to the field of molding dies, and more specifically to a handle mold. Background Technology

[0002] The core characteristics of die casting are high pressure and high speed, which allows liquid or semi-liquid metal to quickly fill the mold cavity and cool and solidify under high pressure, thereby ensuring the density and surface finish of the parts. Die casting can produce parts with thin walls and complex shapes, such as automobile engine blocks and instrument housings.

[0003] In die-casting handles, the outer frame of the handle has uneven thickness. Typically, material is injected into the lower part of the mold cavity, where the larger portion of the part is formed, while the smaller portion is formed in the upper part. However, existing handle molds have runners concentrated in thin-walled and thick-walled areas, making it difficult to effectively adjust the handle forming process. Utility Model Content

[0027] Example 1: See details Figures 1 to 6 This explains the working process of the mold used for casting the handle;

[0028] The handle mold includes a fixed mold 11 with a casting hole 41 at the bottom and a movable mold 21 corresponding to the fixed mold 11. The movable mold 21 can slide linearly and couple with the fixed mold 11. A molding cavity I 14 is provided on the surface where the fixed mold 11 and the movable mold 21 are coupled. A molding cavity II 24 corresponding to the molding cavity I 14 is provided on the movable mold 21. Two liquid supply cavities 43 communicating with the molding cavity II 24 are provided at the bottom of the movable mold 21. A blind hole 42 corresponding to the casting hole 41 is provided at the bottom of the movable mold 21 to supply fluid to the two liquid supply cavities 43. The two liquid supply cavities 43 correspond to the thick-walled area of ​​the molding cavity II 24 respectively. The upper part of the moving mold 21 is provided with two fixed sliders I 31, and the two fixed sliders I 31 are slidably connected to the moving sliders I 27. The lower part of the moving sliders I 27 is provided with forming blocks I 44, and forming blocks II 46 are provided on the forming blocks I 44. The lower part of the moving mold 21 is provided with two pairs of fixed sliders II 32, and each pair of fixed sliders II 32 is slidably connected to the moving sliders II 28. Each moving slider II 28 is provided with a forming block III 47.

[0029] The handle includes a handle body 01. The lower part of the handle body 01 has through holes 02 on both sides. The through holes 02 are rectangular and have arcs at the right angles. The shape of the through holes 02 is not convenient to obtain in subsequent processing, so it needs to be formed by casting to realize the rapid processing of the two through holes 02 and speed up the processing speed of the two through holes 02 on the handle body 01. The upper part of the handle body 01 has a protrusion 03 formed in one piece on one side. The protrusion 03 is spline column-shaped. The middle part of the protrusion 03 has a central hole 04 formed in one piece. The middle part of the handle body 01 is hollow. The thickness of the lower part of the handle body 01 is greater than the thickness of the upper part, and the width of the lower part of the handle body 01 is greater than the width of the upper part.

[0030] The fixed mold 11 is used for fixing and rapidly adding liquid raw materials through the casting hole 41 on the fixed mold 11 under high pressure. The moving mold 21 can slide linearly under external force and couple with the fixed mold 11. The molding cavity II 24 on the moving mold 21 is coupled with the molding cavity I 14 on the fixed mold 11 to form a cavity for molding the handle body 01. The handle body 01 has thick-walled structures on both sides. The two liquid supply cavities 43 correspond to the thick-walled areas of the molding cavity II 24, which can improve the filling efficiency and molding effect of the area.

[0031] When the moving mold 21 slides and couples with the fixed mold 11, the moving slider I 27 slides on the two fixed sliders I 31, and the moving slider I 27 drives the forming block I 44 to slide. After the forming cavity I 14 on the fixed mold 11 is coupled with the forming cavity II 24 on the moving mold 21, it is provided to accommodate the sliding of the forming block I 44 for forming the protrusion 03. The stopping position of the forming block I 44 after sliding is used to control the length of the formed protrusion 03. The forming block II 46 on the forming block I 44 is used to form the central hole 04. When the moving mold 21 slides and couples with the fixed mold 11, the two moving sliders II 28 slide on the two fixed sliders II 32. The two forming blocks III 47 on the two moving sliders II 28 are used to form two through holes 02, which facilitates the direct forming of two rectangular through holes 02 with arcs at the right angles on the handle body 01, thus speeding up the processing efficiency of the handle.

[0032] Liquid raw material flows through casting hole 41 into blind hole 42 and two liquid supply channels 43, and then flows from the two liquid supply channels 43 into molding channel II 24 on moving mold 21 and molding channel I 14 on fixed mold 11 to couple and form a cavity, which simultaneously covers the outside of molding block II 46 and two molding blocks III 47, thus forming the handle in one step. The setting of two liquid supply channels 43 can ensure that when liquid raw material is injected into the cavity formed by molding channel II 24 on moving mold 21 and molding channel I 14 on fixed mold 11, it can be quickly supplied from the middle of the lower part of the cavity to both sides of the lower part of the cavity. This ensures that the lower part of the handle, which requires more raw material, and the upper part, which requires less raw material, have similar molding times. This ensures that the cooling time of the upper and lower parts of the handle is similar during molding, thus avoiding the handle's performance deviation caused by different cooling times, which would result in the processed handle not meeting production requirements and affecting the processing efficiency of the handle.

[0033] After the handle is formed and cooled, the moving mold 21 slides linearly to separate from the fixed mold 11. Then the handle is demolded and collected. The moving slider I 27 and the two moving sliders II 28 are reset. After cooling and cleaning, it is ready for the next handle forming process. The sliding and limiting of the moving mold 21 adopts the power structure and limiting structure in the existing aluminum die casting process to ensure the stable sliding of the moving mold 21.

[0034] Example 2: See details Figure 1 and 3 This explains the process of increasing the accuracy of the coupling between the fixed mold 11 and the moving mold 21;

[0035] Positioning rods 12 are provided at each of the four corners of the fixed mold 11. Positioning holes 22, corresponding one-to-one with the positioning rods 12, are provided on the moving mold 21. Two rectangular holes 13 are provided on the coupling surfaces of the fixed mold 11 and the moving mold 21. Rectangular protrusions 23, which are coupled to the two rectangular holes 13, are provided on the moving mold 21. When the moving mold 21 slides linearly, the multiple positioning holes 22 gradually approach the multiple positioning rods 12 until they are fitted onto the multiple positioning rods 12. This serves to position the moving mold 21 when it is coupled with the fixed mold 11 during linear sliding, ensuring the accuracy of the coupling between the moving mold 21 and the fixed mold 11, thereby increasing the precision of the handle produced by molding.

[0036] When the moving mold 21 slides linearly and couples with the fixed mold 11, two rectangular protrusions 23 slide into two rectangular holes 13 for further positioning. This allows the fixed mold 11 to be further positioned and coupled with the moving mold 21 as the multiple positioning holes 22 gradually approach the multiple positioning rods 12 until they are fitted onto the roots of the multiple positioning rods 12. This increases the accuracy of the coupling between the fixed mold 11 and the moving mold 21 and ensures the accuracy of the handle produced by molding.

[0037] Example 3: See details Figure 1 , 3Sections 4 and 5 explain the process of driving the sliding block I27 to slide when the fixed mold 11 and the moving mold 21 are coupled.

[0038] The movable slider I27 is provided with a slope block I25, and the fixed mold 11 is provided with a slope hole I15 coupled to the slope block I25. When the movable mold 21 slides and couples with the fixed mold 11, the slope block I25 slides into the slope hole I15. The slope of the slope hole I15 guides the slope block I25, causing it to slide under the guidance of the slope block I25. The slope block I25 drives the movable slider I27 to slide, so that when the fixed mold 11 and the movable mold 21 are fully coupled, it can move to the position of the forming protrusion 03 to form the protrusion 03.

[0039] Example 4: See details Figure 3 , 4 Sections 5 and 6 explain the process of driving the two molding blocks Ⅲ47 to slide when the fixed mold 11 and the moving mold 21 are coupled;

[0040] Each movable slider II28 is provided with a slope block II26, and the fixed mold 11 is provided with a slope hole II16 corresponding to each slope block II26.

[0041] When the moving mold 21 slides and couples with the fixed mold 11, the slope block II 26 slides into the slope hole II 16. The slope of the slope hole II 16 guides the slope block II 26 to slide under the guidance of the slope block II 26. The slope block II 26 drives the moving slider II 28 to slide, so that when the fixed mold 11 and the moving mold 21 are fully coupled, it can move to the position of forming the through hole 02 and form the through hole 02.

[0042] Example 5: See details Figure 6 This explains the process of placing the slag bag;

[0043] The moving mold 21 is provided with multiple slag-filled cavities 45 that communicate with the forming cavity II 24. The multiple slag-filled cavities 45 are used to place slag, and the slag is used to filter impurities and oxides. It can discharge the gas generated during the flow of molten aluminum and reduce defects such as porosity. The multiple slag-filled cavities 45 around the forming cavity II 24 can ensure that the forming cavity II 24 is fully connected to the outside and ensure the full forming of the handle.

[0044] Example 6: See details Figure 4 , 5 Sections 6 and 6 illustrate the process of forming the spline-shaped protrusion 03;

[0045] Molding block I 44 is spline-shaped. This allows a protrusion 03, identical in shape to molding block I 44, to be formed within the sliding cavity of molding block I 44. Molding block II 46 is cylindrical. A central hole 04, fitting onto molding block II 46, can be formed on the protrusion 03. Molding block III 47 is rectangular prism-shaped. Two through holes 02, fitting onto the outside of molding block III 47, can be formed using two molding blocks III 47.

[0046] Example 7: See details Figure 4 , 5 Section 6 explains the process of optimizing the supply of material to the cavity of the molded handle:

[0047] Two liquid supply channels 43 are located in the middle of the lower part of the forming channel II 24. This allows the material for forming the handle to be supplied to the handle body through a larger flow channel, which can more quickly meet the lower part of the cavity that has a greater demand for forming the handle. At the same time, it can quickly supply the material for forming the handle from the middle to both sides, and supply the material from both sides to the upper part, which fits the shape of the handle better and ensures the quality and speed of forming the handle.

[0048] The width at the connection between the two liquid supply channels 43 and the forming channel II 24 is greater than the width at the connection with the blind hole 42. This allows the material to be supplied to the two liquid supply channels 43 through the blind hole 42, and then quickly and evenly and stably supplied to both sides of the upper end of the liquid supply channels 43 to form the handle, thus achieving stable, fast and precise forming of the handle.

[0049] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
