Description

Technical Field

[0001] The invention relates to a die-casting mould with a slag removal structure. Background Art

[0002] At present, most die-casting molds with sliders, whether they are inclined pin core pulling or cylinder core pulling, will have the phenomenon of mold sliders escaping and not being able to be fully laminated after a long period of production, resulting in unqualified die-casting parts. There are many reasons for this situation, the most important of which is the excessive accumulation of garbage inside the slider and chute. Therefore, most molds will regularly clean the slider area during the production process. Although the bottom surface of the slider of the die-casting mold is generally equipped with an escape space with the bottom surface of the mold frame, the waste slag cannot be discharged well. Over time, it will inevitably lead to the accumulation of garbage in the chute, and the slider cannot be reset, which seriously affects the product quality. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a die-casting mold with a slag removal structure in order to overcome the defect in the prior art that excessive garbage accumulation inside the slider and the chute causes the slider travel to be blocked.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A die-casting mold with a slag discharge structure is characterized in that the die-casting mold with a slag discharge structure comprises a fixed mold, an upper slider, a lower slider, a movable mold core, a movable mold frame and an upper drainage channel, wherein:

[0006] The movable mold frame includes a receiving cavity, an upper end platform adjacent to the upper part of the receiving cavity, and a lower end platform adjacent to the lower part of the receiving cavity;

[0007] One side of the movable mold core is buried in the accommodating cavity, the upper end platform is attached to the upper end of the movable mold core, and the lower end platform is attached to the lower end of the movable mold core;

[0008] The upper slider and the lower slider are respectively located at the upper and lower sides of the movable mold core, and the upper slider and the lower slider are slidably arranged on the movable mold frame;

[0009] The upper drainage channel extends through the upper end surface of the movable mold core and the movable mold frame. A mold frame drainage hole is opened below the upper end platform, and the drainage channel is communicated with the mold frame drainage hole.

[0010] During the cleaning process of the die-casting mold, due to the obstruction of the upper end surface of the movable mold core, the dirt flowing down from the upper cleaning is easy to accumulate on the upper end surface of the movable mold core, especially at the junction of the movable mold core and the upper end of the movable mold frame. At this time, the movement of the slider will be blocked, affecting the stroke.

[0011] In this solution, by setting the upper drainage channel, the dirt left on the upper end surface of the movable mold core after washing will be guided to flow into the mold frame drainage hole and discharged. At this time, the residue at the junction of the upper end surface of the movable mold core and the upper end table will no longer accumulate, thereby ensuring that the travel of the upper slider will not be blocked.

[0012] Preferably, the upper drainage channel is a guide groove opened at the lower edge of the upper end platform, and the guide groove is adjacent to the upper end surface of the movable mold core. Thus, the guide groove is completely located at the position where the residue is most likely to accumulate, so that the washed residue can be well guided into the mold frame drainage hole.

[0013] Preferably, the die-casting mold with slag discharge structure further includes a lower drainage channel, wherein:

[0014] The lower drainage channel is formed on the surface of the movable mold core and the lower end platform;

[0015] The lower drainage channel sequentially extends through the front end surface of the movable mold core, the lower end surface of the movable mold core and the surface of the lower end platform.

[0016] Although the residue at the junction of the lower end surface of the movable mold core and the lower end platform will fall due to gravity, it is still easy to accumulate after long-term accumulation.

[0017] In this solution, by setting up the lower drainage channel, the dirt left at the junction of the lower end surface of the movable mold core and the lower end table will be guided downward to flow into the lower end table and discharged. At this time, the residue at the junction of the lower end surface of the movable mold core and the lower end table will no longer accumulate, thereby ensuring that the travel of the lower slider will not be blocked.

[0018] Preferably, the lower end platform is provided with an escape position, and the lower drainage channel is connected to the escape position. The escape position has a larger space, so that the lower drainage channel can more easily discharge the residue.

[0019] Preferably, the lower drainage channel includes a core drainage groove and a mold frame drainage groove that are interconnected, wherein the core drainage groove is opened in the movable core, and the mold frame drainage groove is opened in the lower end platform. The core drainage groove and the mold frame drainage groove cover all positions where residues are easily accumulated.

[0020] Preferably, the mold core drainage groove extends through the front end surface of the movable mold core and the lower end surface of the movable mold core. Thus, the mold core drainage groove is completely located at the position where the movable mold core is most likely to accumulate residues, thereby being able to well guide the washed residues.

[0021] Preferably, the mold frame drainage groove is opened at the upper edge of the lower end platform, so that the mold frame drainage groove is completely located at the position of the lower end platform where the residue is most likely to accumulate, so that the washed residue can be well guided.

[0022] Preferably, the mold frame drainage hole extends downwardly in an inclined manner, thereby guiding the discharge of residues.

[0023] Preferably, the die-casting mold with a slag removal structure includes a slider parting mechanism, and the slider parting mechanism connects the upper slider and the lower slider.

[0024] Preferably, the slider parting mechanism is a cylinder or an inclined guide column.

[0025] The positive improvement effect of the present invention is that through the use of the present invention, the accumulation of garbage inside the die-casting mold is reduced, especially the frequency of cleaning the garbage inside the slider is reduced, thereby improving production efficiency.

[0032] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0033] like Figure 1-Figure 6 As shown, this embodiment discloses a die-casting mold with a slag discharge structure, the die-casting mold with a slag discharge structure includes a fixed mold 5, an upper slider 31, a lower slider 32, a movable mold core 1, a movable mold frame 2 and an upper drainage channel, wherein:

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the movable mold frame 2 includes a receiving cavity 27, an upper end platform 21 adjacent to the upper part of the receiving cavity 27, and a lower end platform 22 adjacent to the lower part of the receiving cavity.

[0035] One side of the movable mold core 1 is buried in the accommodating cavity 27 , the upper end platform 21 is attached to the upper end of the movable mold core 1 , and the lower end platform 22 is attached to the lower end of the movable mold core 1 .

[0036] The upper slider 31 and the lower slider 32 are respectively located at the upper and lower sides of the movable mold core 1 , and the upper slider 31 and the lower slider 32 are slidably disposed on the movable mold frame 2 .

[0037] like Figure 6 As shown, the movable mold core 1 includes an upper end surface 11 , a lower end surface 12 and a front end surface 14 .

[0038] like Figure 2 As shown, the upper drainage channel extends through the upper end surface 11 of the movable mold core 1 and the movable mold frame 2 , and a mold frame drainage hole 24 is opened below the upper end platform 21 , and the drainage channel is connected to the mold frame drainage hole 24 .

[0039] During the cleaning process of the die casting mold, due to the obstruction of the upper end surface 11 of the movable mold core 1, the dirt flowing down from the upper cleaning is easy to accumulate on the upper end surface 11 of the movable mold core 1, especially at the junction of the movable mold core 1 and the upper end platform 21 of the movable mold frame 2. At this time, the movement of the slider will be blocked, affecting the stroke.

[0040] In this embodiment, by setting the upper drainage channel, the dirt left on the upper end surface 11 of the movable mold core 1 after washing will be guided to flow into the mold frame drainage hole 24 and discharged. At this time, the residue at the junction of the upper end surface 11 of the movable mold core 1 and the upper end platform 21 will no longer accumulate, thereby ensuring that the travel of the upper slider 31 will not be blocked.

[0041] like Figure 2 As shown, the upper drainage channel is a guide groove 23 opened at the lower edge of the upper end platform 21, and the guide groove 23 is adjacent to the upper end surface 11 of the movable mold core 1. Therefore, the guide groove 23 is completely in the position where the residue is most likely to accumulate, so that the washed residue can be well guided into the mold frame drainage hole 24.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, the die-casting mold with slag discharge structure in this embodiment also includes a lower drainage channel, wherein:

[0043] The lower drainage channel is formed on the surface of the movable mold core 1 and the lower end platform 22 .

[0044] The lower drainage channel sequentially extends through the front end surface 14 of the movable mold core 1 , the lower end surface 12 of the movable mold core 1 , and the surface of the lower end platform 22 .

[0045] Although the residue at the junction of the lower end surface 12 of the movable mold core 1 and the lower end platform 22 will fall due to gravity, it is still easy to accumulate after long-term accumulation.

[0046] In this embodiment, by setting the lower drainage channel, the dirt left at the junction of the lower end surface 12 of the movable mold core 1 and the lower end platform 22 will be guided downward to flow into the lower end platform 22 and discharged. At this time, the residue at the junction of the lower end surface 12 of the movable mold core 1 and the lower end platform 22 will no longer accumulate, thereby ensuring that the travel of the lower slider 32 will not be blocked.

[0047] In this embodiment, a clearance position 26 is provided on the lower end platform 22, and the lower drainage channel is connected to the clearance position 26. The clearance position 26 has a large space, so that the lower drainage channel can more easily discharge the residue.

[0048] like Figure 3 , Figure 5 and Figure 6 As shown, the lower drainage channel includes a core drainage groove 13 and a mold frame drainage groove 25 which are interconnected, wherein the core drainage groove 13 is opened on the movable core 1, and the mold frame drainage groove 25 is opened on the lower end platform 22. The core drainage groove 13 and the mold frame drainage groove 25 cover all positions where residues are easily accumulated.

[0049] like Figure 6 As shown, the mold core drainage groove 13 extends through the front end surface 14 of the movable mold core 1 and the lower end surface 12 of the movable mold core 1. Therefore, the mold core drainage groove 13 is completely located at the position where the movable mold core 1 is most likely to accumulate residues, so that the washed residues can be well guided.

[0050] like Figure 5 As shown, the mold frame drainage groove 25 is opened at the upper edge of the lower end platform 22. Thus, the mold frame drainage groove 25 is completely located at the position where the lower end platform 22 is most likely to accumulate residues, thereby being able to guide the washed residues well.

[0051] In this embodiment, the mold frame drain hole 24 extends downwardly in an inclined manner, thereby guiding the discharge of the residue.

[0052] In this embodiment, the die-casting mold with the slag removal structure may further include a slider parting mechanism, and the slider parting mechanism connects the upper slider 31 and the lower slider 32 .

[0053] The slider parting mechanism of the present embodiment is an inclined guide column 4. Of course, an oil cylinder may also be selected in other embodiments.

[0054] like Figure 4 As shown, after the die-casting mold with the slag discharge structure is opened, spraying is performed, and water flows out from the mold frame drainage holes 24 and the avoidance positions 26 along the directions of the arrows in the figure, thereby effectively avoiding the accumulation of residues.

[0055] The positive improvement effect of the present invention is that through the use of the present invention, the accumulation of garbage inside the die-casting mold is reduced, especially the frequency of cleaning the garbage inside the slider is reduced, thereby improving production efficiency.

[0056] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims.
