Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically a die casting mold. Background Technology

[0002] Die casting molds are a method of casting liquid forging, a process completed on a dedicated die casting and forging machine. Die casting molds are one of the three essential elements of die casting production, and none can be omitted. The so-called die casting process is to organically integrate these three elements to stably, rhythmically, and efficiently produce qualified castings, or even high-quality castings, with good appearance and internal quality and dimensions that meet the requirements of drawings or agreements.

[0003] Existing die-casting molds require manual demolding of the product after die-casting, which is time-consuming and labor-intensive and cannot achieve fast and automatic demolding. Therefore, this utility model proposes a die-casting mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a die-casting mold that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-casting mold, including a lower mold base, and further comprising:

[0006] An upper mold base, which is located above the lower mold base, and an upper template is connected to the bottom of the upper mold base;

[0007] The lower template is located at the upper end of the lower mold base;

[0008] A demolding assembly, wherein the demolding assembly is located in the middle of the lower mold base;

[0009] The demolding assembly includes an extrusion block, an extrusion groove at the upper end of the lower template, an auxiliary slide groove inside the extrusion groove, a force-bearing block inside the extrusion groove, an auxiliary slider and a first support column connected to the outside of the force-bearing block, a base plate connected to the bottom of the first support column, a second support column at the upper end of the base plate, a moving hole, a first spring on the outside of the second support column, a demolding template connected to the end of the second support column, a compression groove, and a second spring inside the compression groove.

[0010] Furthermore, a die-casting mold also includes:

[0011] Inserted columns are located at the bottom of the upper template, and there are four sets of inserted columns arranged in an array. The inserted columns are fixedly connected to the upper template.

[0012] Furthermore, a die-casting mold also includes:

[0013] The slots are located at the upper end of the lower template, and the number of slots is equal to the number of pins, and the pins and slots are adapted to each other;

[0014] The inner cavity is located at the upper end of the lower template;

[0015] A limiting block is located at the bottom of the upper template and is adapted to the inner cavity.

[0016] Furthermore, a die-casting mold also includes:

[0017] The injection port penetrates the middle of the upper mold base, the upper template, and the limiting block.

[0018] Furthermore, the extrusion block is connected to the extrusion groove, the lower mold base has an inner cavity, and the inner cavity is connected to the die casting cavity through a moving hole, and the inner cavity is connected to the extrusion groove through a moving hole.

[0019] Furthermore, the auxiliary slider and the auxiliary slide groove are adapted to each other, the first support column is fixedly connected to the base plate, the second support column is fixedly connected to the demolding template, the two ends of the first spring are respectively connected to the inner cavity and the base plate, and the two ends of the second spring are respectively connected to the base plate and the compression groove.

[0020] Compared to the aforementioned background technology, the die-casting mold provided in this application includes a lower mold base, an upper mold base, an inner cavity, a limiting block, and a demolding assembly. In order to achieve automatic demolding of the die-cast product, when the lower mold base and the upper mold base are engaged, the extrusion block squeezes the force block, causing the first support column and the base plate to descend, which in turn causes the base plate to drive the demolding plate to descend. At the same time, the first spring is stretched and the second spring is compressed. After the product is die-cast, when the lower mold base is removed, the first spring and the second spring reset, causing the demolding plate to push the product out, thereby achieving automatic demolding of the product.

[0021] This invention provides a die-casting mold. Compared with the prior art, it has the following advantages:

[0022] A die-casting mold, by setting a demolding component between the lower mold base and the upper mold base, when the product is demolded, moves the upper mold base and the upper template out, simultaneously moving the limiting block out of the inner cavity, and the extrusion block moving out along the extrusion groove. Under the elastic potential energy of the second spring and the first spring, the bottom plate rises, causing the first support column to drive the force-bearing block to rise along the extrusion groove, and simultaneously driving the auxiliary slider to slide along the auxiliary slide groove. Further, the second support column rises along the moving hole, and simultaneously drives the demolding template to push out the product. At this time, the stretching force of the first spring and the compression force of the second spring are reset, keeping both in their initial state. The structure is simple, the operation is convenient, and it is easy to automatically demold the product. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a die-casting mold technical solution: a die-casting mold, including a lower mold base 1, and further including: an upper mold base 2, the upper mold base 2 being located at the upper end of the lower mold base 1, and an upper template 4 connected to the bottom of the upper mold base 2; a lower template 3, the lower template 3 being located at the upper end of the lower mold base 1; and a demolding assembly 10, the demolding assembly 10 being located in the middle of the lower mold base 1; the demolding assembly 10 includes an extrusion block 101, an extrusion groove 102 opened at the upper end of the lower template 3, and an auxiliary sliding groove 103 opened inside the extrusion groove 102. The compression groove 102 includes a force-bearing block 104 inside, an auxiliary slider 105 and a first support column 106 connected to the outside of the force-bearing block 104, a base plate 107 connected to the bottom of the first support column 106, a second support column 108 at the upper end of the base plate 107, a moving hole 109, a first spring 1010 on the outside of the second support column 108, a release template 1011 connected to the end of the second support column 108, a compression groove 1012, and a second spring 1013 inside the compression groove 1012.

[0030] Among them, the insert 5 is located at the bottom of the upper mold plate 4, and there are four sets of insert 5 arranged in an array. The insert 5 is fixedly connected to the upper mold plate 4. The slot 6 is located at the upper end of the lower mold plate 3, and the number of slots 6 is equal to that of insert 5. The insert 5 and slot 6 are compatible. The limiting block 8 is located at the bottom of the upper mold plate 4 and is compatible with the die casting cavity 7. The injection port 9 penetrates the middle of the upper mold base 2, the upper mold plate 4 and the limiting block 8, which is conducive to the die casting of the product.

[0031] In addition, the extrusion block 101 is connected to the extrusion groove 102. The lower mold base 1 has an internal cavity, which is connected to the die casting cavity 7 through a moving hole 109. The internal cavity is connected to the extrusion groove 102 through a moving hole 109. The auxiliary slider 105 is adapted to the auxiliary slide groove 103. The first support column 106 is fixedly connected to the base plate 107. The second support column 108 is fixedly connected to the demolding template 1011. The two ends of the first spring 1010 are connected to the internal cavity and the base plate 107 respectively. The two ends of the second spring 1013 are connected to the base plate 107 and the compression groove 1012 respectively. This facilitates the demolding assembly 10 to automatically eject the product after die casting is completed, when the upper mold base 2 drives the upper template 4 and the limiting block 8 to leave the die casting cavity 7.

[0032] During use, the upper mold base 2 is placed on top of the lower mold base 1, the insert pin 5 is inserted into the slot 6, and the limiting block 8 is inserted into the die casting cavity 7. The demolding component 10 is further compressed. After the lower mold base 1 and the upper mold base 2 are fixed, liquid is injected into the die casting cavity 7 through the injection port 9. When the product is being formed, the demolding component 10 can automatically demold the product when the lower mold base 1 is removed.

[0033] It should be noted that, through the setting of the demolding component 10, when the product is demolded, the upper mold base 2 and the upper template 4 are moved out, and the limiting block 8 is moved out of the die-casting cavity 7. At the same time, the extrusion block 101 moves out along the inside of the extrusion groove 102. Under the elastic potential energy of the second spring 1013 and the first spring 1010, the bottom plate 107 rises, causing the first support column 106 to drive the force block 104 to rise along the inside of the extrusion groove 102. At the same time, the auxiliary slider 105 slides along the inside of the auxiliary slide groove 103, further causing the second support column 108 to rise along the inside of the moving hole 109. At the same time, the demolding template 1011 pushes the product out. At this time, the stretching force of the first spring 1010 and the compression force of the second spring 1013 are reset, keeping both in their initial state. The structure is simple, the operation is convenient, and it is easy to automatically demold the product.
