Description

Technical Field

[0001] This utility model belongs to the field of casting mold technology, and more specifically, it relates to a flow divider cone for aluminum alloy die casting mold. Background Technology

[0002] Nowadays, more and more automotive parts are made of aluminum or magnesium alloys, such as the housings of engines, transmissions, or motors. These aluminum alloy automotive parts are mass-produced using large high-pressure die-casting molds. During production, the flow divider cone is subjected to frequent high-temperature and high-pressure erosion, resulting in a relatively short lifespan for the flow divider cone. With continued use, problems such as cracks and leaks will appear, requiring replacement with new flow divider cone parts. The appearance of cracks and leaks is due to the flow divider cone's inability to fully meet the high-temperature and high-pressure operating requirements. Local temperature differences can easily occur in different parts of the flow divider cone, causing changes in the molecular structure of the material in areas with larger temperature differences, thus leading to cracks.

[0003] Based on the above, the following problems were found: When using existing flow dividers, the flow rate is fixed. When dividing different raw materials, different flow rates are required due to the different viscosities of the raw materials. Flow dividers usually have cooling channels inside the cone for cooling. However, the contact area between the cooling channels and the cone is small, resulting in poor cooling effect. Furthermore, because flow dividers are frequently subjected to high temperatures and high pressures, they are prone to damage and need to be replaced frequently. Replacing the entire flow divider also results in a waste of resources.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an aluminum alloy die-casting mold flow divider cone to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an aluminum alloy die-casting mold flow divider cone, which solves the problems of fixed flow rate and poor cooling effect caused by the small contact area between the cooling channel and the flow divider cone during use.

[0006] This utility model provides an aluminum alloy die-casting mold flow divider cone, which is achieved by the following specific technical means:

[0007] A flow divider cone for aluminum alloy die casting includes a cone base and a cone head. A flow channel is provided on one side of the top of the cone head. The middle part of the cone base and the bottom of the slot are movably connected. A slot is provided at the bottom of the cone base. A locking block is fixed at the bottom of the cone head. A limit ring is fixed at the middle of the cone head. A water outlet and a water inlet are provided through the bottom of the cone head. A cooling channel is provided inside the cone head. A connecting ring is detachably installed on the outer wall of the cone head. A flow block is fixed on one side of the connecting ring. The flow block is located inside the flow channel.

[0008] Furthermore, a groove is provided at the bottom of the cone-shaped body, the locking block is located inside the groove, the outer wall of the locking block is arc-shaped, and a spring is fixed to the inner wall of the locking block. One end of the spring is fixed to the inner wall of the locking block, and the other end of the spring is fixed to the groove.

[0009] Furthermore, multiple card slots and multiple card blocks are provided, with each of the multiple card blocks corresponding to one of the multiple card slots.

[0010] Furthermore, the cooling channel is arranged in a spiral filling shape inside the cone-shaped body, with one end of the cooling channel connected to the water outlet and the other end connected to the water inlet.

[0011] Furthermore, one side of the drainage block is fitted to the inner wall of the drainage channel, and an arc-shaped pad is fixed on the top of the drainage block to cover the gap between the drainage block and the top of the drainage channel.

[0012] Furthermore, multiple drainage blocks are provided, and the curvature of each drainage block near its outer wall is adapted to the curvature of the drainage channel. The curvature of the inner wall of each drainage block is arranged in a progressively decreasing manner.

[0013] Furthermore, the outer wall of the connecting ring is threaded with a fastening bolt, one end of which is threaded to the outer wall of the cone head.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, a cooling channel is set inside the cone body by spiral ring, which increases the contact area between the water flow and the inside of the cone body. This allows the water entering from the inlet to fully contact the inside of the cone body, absorb the heat of the cone body, and then be discharged from the outlet. The original diverting cone is divided into a cone base and a cone body. When damaged, the cone body can be replaced separately, and the replacement method is simple. This achieves the effect of rapid cooling and improved service life. Furthermore, the diverting cone is set in two parts, and the cone body can be replaced separately, making replacement more convenient and saving resources.

[0016] 2. In this utility model, when changing production raw materials, a diversion block can be used. The diversion block is placed on the diversion channel for use. The diversion block is suitable for diverting a small amount of raw materials. Multiple diversion blocks with different curvatures can be selected according to the viscosity of the production raw materials to ensure effective control of the diversion flow rate of the diversion cone. This allows for the selection of the diversion slope according to the diverted raw materials, thereby quickly adjusting the flow rate. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an aluminum alloy die-casting mold flow divider cone, including a cone base 1 and a cone head 3. A flow guide groove 6 is provided on one side of the top of the cone head 3. The middle part of the cone base 1 and the bottom of the slot 2 are movably connected. A slot 2 is provided at the bottom of the cone base 1. A locking block 4 is fixed at the bottom of the cone head 3. A limit ring 5 is fixed in the middle of the cone head 3. A water outlet 7 and a water inlet 8 are provided through the bottom of the cone head 3. A cooling flow channel 13 is provided inside the cone head 3. A connecting ring 9 is detachably installed on the outer wall of the cone head 3. A flow guide block 10 is fixed on one side of the connecting ring 9. The flow guide block 10 is located inside the flow guide groove 6.

[0028] The cone head 3 has a groove at its bottom, and the locking block 4 is located inside the groove. The outer wall of the locking block 4 is arc-shaped, and a spring is fixed to the inner wall of the locking block 4. One end of the spring is fixed to the inner wall of the locking block 4, and the other end of the spring is fixed to the groove. The spring supports the locking block 4. When the cone head 3 needs to be replaced, the old cone head 3 is removed, and the new cone head 3 is inserted into the cone base 1. The arc-shaped locking block 4 will squeeze the spring and enter the groove.

[0029] The device includes multiple slots 2 and multiple locking blocks 4, with each locking block 4 corresponding to a different slot 2. When the cone head 3 enters the cone base 1, the limiting ring 5 fits against the top of the cone base 1, and the spring releases its elastic potential energy, pushing the multiple locking blocks 4 into the slots 2 to connect the cone head 3 and the cone base 1, forming a whole for use. When damaged, only the cone head 3 needs to be replaced. The cone head 3 is produced faster using 3D printing.

[0030] The cooling channel 13 is arranged in a spiral filling shape inside the cone body 3. One end of the cooling channel 13 is connected to the outlet 7, and the other end of the cooling channel 13 is connected to the inlet 8. The cooling channel 13 is arranged in a spiral ring inside the cone body 3, which increases the contact area between the water flow and the inside of the cone body 3. This allows the water entering from the inlet 8 to fully contact the inside of the cone body 3, absorb the heat of the cone body 3, and then be discharged from the outlet 7.

[0031] The diversion block 10 is connected to the inner wall of the diversion channel 6 in a fitted manner on one side. An arc-shaped pad 11 is fixed on the top of the diversion block 10. The arc-shaped pad 11 is used to cover the gap between the top of the diversion block 10 and the top of the diversion channel 6. Under normal use, the diversion channel 6 is used alone for diversion. When changing the production raw materials, the diversion block 10 can be used. The diversion block 10 is placed on the diversion channel 6 for use. The diversion block 10 is suitable for diverting a small amount of raw materials during production.

[0032] The system includes multiple diversion blocks 10, each of which is adapted to the curvature of the diversion channel 6 near its outer wall. The curvature of the inner walls of the multiple diversion blocks 10 decreases sequentially, allowing the selection of multiple diversion blocks 10 with different curvatures to correspond to the viscosity of the raw materials and ensure effective control of the diversion flow rate of the diversion cone.

[0033] The outer wall of the connecting ring 9 is threaded with a fastening bolt 12. One end of the fastening bolt 12 is threaded to the outer wall of the cone body 3. When the drainage block 10 needs to be used or replaced, the connecting ring 9 is fitted onto the outer wall of the cone body 3, and the fastening bolt 12 is used to fix the connecting ring 9 onto the cone body 3, thereby fixing the drainage block 10 onto the drainage groove 6.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, during the initial flow division, the flow is divided through the diversion channel 6, while cooling water is injected through the inlet 8. A cooling channel 13 is spirally annularly arranged inside the cone body 3, increasing the contact area between the water flow and the interior of the cone body 3. This allows the water entering through the inlet 8 to fully contact the interior of the cone body 3, absorbing heat before being discharged from the outlet 7. When changing production materials, the diversion block 10 can be used, covering the diversion channel 6. The diversion block 10 is suitable for diverting small quantities of raw materials. Multiple diversion blocks 10 with different curvatures can be selected according to the viscosity of the production material, ensuring effective flow division by the diversion cone. The flow rate is effectively controlled. When the flow guide block 10 needs to be used or replaced, the connecting ring 9 is fitted onto the outer wall of the cone body 3, and then the connecting ring 9 is fixed to the cone body 3 by using the fastening bolt 12. In this way, the flow guide block 10 is fixed to the flow groove 6. When the cone body 3 is damaged after long-term use, the old cone body 3 is removed, and the new cone body 3 is inserted into the cone base 1. The arc-shaped locking block 4 will squeeze the spring and enter the groove. Multiple locking blocks 4 push into the locking groove 2, connecting the cone body 3 and the cone base 1 to form a whole for use. When damaged and replaced, only the cone body 3 needs to be replaced. The cone body 3 is produced faster when using 3D printing.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
