[0004] 2. High cost: Due to complicated process, serious material waste and high labor cost, the manufacturing cost of the final product is high.
[0005] 3. Unstable quality: Manual operation and equipment precision limit the consistency and stability of product quality, which is prone to size deviation, internal defects and other problems.
[0006] 4. Poor design flexibility: For some special structure or complex geometric shape elbow, traditional method is difficult to realize accurate forming, which limits the freedom of product design.
[0007] In recent years, with the development of industrial automation and technological progress, die casting technology has gradually become an ideal choice to replace traditional processing methods. However, for the specific type of right angle steering elbow, the existing die casting mold on the market still has the following problems:

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.
[0035] like Figures 1-4 As shown, this utility model provides a die-casting mold for a right-angle steering bend, comprising:
[0036] The upper die 100 and the lower die 200 have the mold core 300 between them, and the mold core 300 encloses the cavity 310 for forming the product after the upper die 100 and the lower die 200 are closed;
[0037] The sliding blocks 210 are provided in plurality and distributed on the lower die 200, and the sliding blocks 210 can move towards the direction close to or away from the mold core 300, and each sliding block 210 is provided with the product shaping column 211 at the end close to the mold core 300, and when each sliding block 210 is moved to the position, the respective product shaping column 211 enters the cavity 310 and is spliced into the shape of the product, at this time, the structure spliced by the product shaping column 211 and the cavity 310 forms a gap, the casting liquid is injected into the cavity 310 and fills the gap, and the product of the right-angle turning elbow pipe is formed after the product is solidified.
[0038] That is, the die casting die provided by the embodiment can form the right-angle turning elbow pipe at one time, without the secondary processing of the bending part of the product, thereby improving the production efficiency and ensuring the product quality and the consistency of the product forming.
[0039] In addition, when the product is demolded, each sliding block 210 only needs to be controlled to move away from the mold core 300, and each product shaping column 211 can automatically separate outward from the formed product, thereby facilitating the demolding.
[0040] Preferably, the number of the sliding blocks 210 is four and is respectively located at each corner position of the lower die 200, and the top surface of each sliding block 210 is provided with the insertion hole 212, and correspondingly, the bottom surface of the upper die 100 is provided with four inclined guide columns 110, and the four inclined guide columns 110 are inclined and inserted into the insertion hole 212 one by one.
[0041] The linkage mechanism between the inclined guide column 110 and the sliding block 210 is specifically described as follows:
[0042] 1. Closing process:
[0043] When the upper die 100 is closed to the lower die 200, the four inclined guide columns 110 at the bottom of the upper die 100 are gradually inserted into the insertion hole 212 of the corresponding sliding block 210, and since the inclined guide column 110 is inclined, a horizontal component force is generated during the insertion process, which promotes the sliding block 210 to move along the predetermined path towards the mold core 300.
[0044] With the gradual approach of the sliding block 210, the product shaping column 211 installed thereon also enters the cavity 310 and finally splices the internal shape of the product.
[0045] 2. Opening process:
[0046] When the mold is opened, the upper mold 100 moves away from the lower mold 200, at this time, the inclined guide posts 110 are extracted from the insertion holes 212 of the sliding blocks 210, and the inclined angle of the inclined guide posts 110 is such that, in the process of extraction, the sliding blocks 210 are subjected to horizontal components in the opposite direction, thereby pushing them away from each other;
[0047] In this way, the product shaping columns 211 on the sliding blocks 210 will be separated from the formed product, facilitating the taking out of the finished product without damaging the surface or structural integrity.
[0048] That is, through the cooperation of the inclined guide posts 110 and the insertion holes 212 of the sliding blocks 210, the precise guidance and positioning of the sliding blocks 210 are realized, ensuring that each time the mold is closed, the ideal splicing effect can be achieved, and the entire closing and opening process does not require manual intervention, but is completely automatic according to the structural characteristics of the mold, thereby improving production efficiency.
[0049] Similarly, when the mold is opened, only the upper mold 100 needs to move away from the lower mold 200, and the sliding blocks 210 can automatically move outward under the action of the inclined guide posts 110, thereby causing the product shaping columns 211 to automatically separate from the formed product.
[0050] Preferably, the mold core 300 is also provided with a positioning member 320, and the product shaping columns 211 pass through the positioning member 320, and the positioning member 320 ensures that each movement of the product shaping columns 211 is along a precise path, thereby ensuring the precision of the splicing of the product shaping columns 211.
[0051] Preferably, the mold core 300 is also provided with a plurality of exhaust channels 330, one end of the exhaust channel 330 communicates with the cavity 310 and the other end extends outward, and the exhaust channel 330 is used to exhaust the air in the cavity 310, thereby reducing or avoiding defects such as air bubbles and shrinkage holes in the castings.
[0052] Preferably, the lower mold 200 is also provided with a feeding guide sleeve 220 and a feeding channel 230, both ends of the feeding channel 230 communicate with the feeding guide sleeve 220 and the cavity 310, and the upper mold 100 is also provided with a feeding port 120, the feeding port 120 is arranged in the upper and lower corresponding positions of the feeding guide sleeve 220, and after the casting liquid enters the feeding port 120, it can enter the cavity 310 along the feeding channel 230.
