[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0028] like Figures 1 to 4 As shown, the utility model is a die-casting mold that is easy to form and quickly demold, comprising: a fixed die seat 1; a movable die seat 2, which is movably arranged below the fixed die seat 1, and when the movable die seat 2 is attached to the fixed die seat 1, a product cavity 20 is formed between the fixed die seat 1 and the movable die seat 2; a first molding component 3, a second molding component 4 and a third molding component 5, which are symmetrically distributed on the movable die seat 2 in an annular shape, the first molding component 3 is provided with a first molding block 30, the second molding component 4 is provided with a second molding block 41, and the third molding component 5 is provided with a third molding block 50, the first molding block 30, the second molding block 41, the ... The molding block 41 and the third molding block 50 are close to each other to enclose a ring-shaped product cavity 20; the core 7 is arranged in the movable mold base 2, and the top wall of the core 7 is provided with a first ejector hole 70, and the side wall is provided with a second ejector hole 71 and a molding groove 72 located above it, and the molding groove 72 is used to form the reinforcing ribs of the inner wall of the product. The core 7 is used to extend into the product cavity 20 to cooperate with the molding blocks to form the required product, and the first ejector hole 70 is pressed against the top wall of the product, and the second ejector hole 71 is pressed against the reinforcing ribs of the side wall of the product, so that the molded product can be smoothly separated from the product cavity 20.
[0029] This solution is mainly for forming hollow cylindrical products with thin wall thickness (not shown in the figure), such as Figure 1 and Figure 4As shown, the first molding component 3, the second molding component 4 and the third molding component 5 in this embodiment are distributed in an annular symmetrical manner, so that the three molding blocks at different positions on the movable mold base 2 are close to each other and cooperate with the core 7 to enclose the required product cavity 20. This design is conducive to reducing the clamping force between each molding block and the molded product, and avoiding damage to the product due to excessive clamping force when the molding block is away from the product cavity 20. In addition, the top wall and the side wall of the core 7 are respectively provided with a first ejector hole 70 and a second ejector hole 71. During the product molding process, the molding located above the second ejector hole 71 The groove 72 can form a reinforcing rib on the inner wall of the formed product (not shown in the figure). It is worth noting that the second ejector hole 71 is arranged corresponding to the reinforcing rib. While enhancing the wall thickness strength of the product to prevent the product from being deformed, the ejector in the second ejector hole 71 can be moved to press against the reinforcing rib to achieve pre-positioning of the formed product before ejection. The ejector in the first ejector hole 70 on the bottom wall of the core 7 is pressed against the top wall of the product, which effectively ensures that the product can be smoothly separated from the product cavity 20, improves the smoothness and stability of the product during demolding, and also provides a guarantee for the quality of the formed product and the product qualification rate.
[0030] The first molding assembly 3 , the second molding assembly 4 and the third molding assembly 5 all include: a fixed block 60 symmetrically arranged in the movable mold base 2 ; a movable block 61 movably clamped on the fixed block 60 , and the first molding block 30 or the second molding block 41 or the third molding block 50 is connected to the movable block 61 .
[0031] Furthermore, with regard to the movement of each of the above-mentioned molding blocks, the three molding blocks are respectively driven by the moving block 61 to approach or move away from the product cavity 20. Due to the movable clamping connection between the moving block 61 and the fixed block 60, a guiding effect is given to the moving block 61 during the reciprocating movement. Preferably, the fixed block 60 in this scheme can be a detachable installation method, so that when wear occurs between the fixed block 60 and the moving block 61, they can be disassembled and replaced in time, which is beneficial to improving the stability of the die-casting mold during operation.
[0032] Preferably, in this solution, a guide groove 600 is provided on the fixed block 60, and guide blocks 610 are formed on both sides of the movable block 61. The guide blocks 610 are movably connected to the guide grooves 600, so that the movable block 61 drives the molding block to move back and forth in the same direction during the process of approaching or moving away from the product cavity 20, thereby effectively ensuring the quality of the product molded in the product cavity 20 surrounded by the three molding blocks and the core 7, thereby improving the product qualification rate.
[0033] The moving block 61 is provided with an inclined guide hole 611 , and the fixed mold base 1 is provided with an inclined guide column 10 , which is movably inserted in the inclined guide hole 611 to drive the moving block 61 to approach or move away from the product cavity 20 .
[0034] Furthermore, with respect to the reciprocating movement of the molding blocks driven by the moving block 61, when the movable mold base 2 and the fixed mold base 1 are closing the mold, the present solution can insert the guide column 11 into the guide hole 22, so that the moving block 61 can drive the three molding blocks to approach the product cavity 20 at the same time. While realizing the driving function, the inclined guide column 10 can also be used to complete the locking function of the moving block 61 and the three molding blocks, thereby ensuring the stability of the die-casting mold during the product molding process.
[0035] Preferably, in addition to the above-mentioned driving methods, other driving devices such as hydraulic driving and cylinder driving can also be used to connect the moving block 61 to achieve the three molding blocks approaching or moving away from the product cavity 20.
[0036] The movable mold base 2 is also provided with an avoidance inclined groove 21 located below the moving block 61 , and the avoidance inclined groove 21 is used to prevent collision between the inclined guide column 10 and the movable mold base 2 .
[0037] Furthermore, when the movable mold base 2 and the fixed mold base 1 are in mold closing action, the inclined guide pin 10 is inserted into the inclined guide hole 611, and the design of avoiding the inclined groove effectively avoids the position between the inclined guide pin 10 and the movable mold base 2 and the jamming phenomenon, which provides sufficient space for the displacement of the inclined guide pin 10 and ensures the smoothness and stability of the die-casting mold during operation.
[0038] Preferably, the present solution further provides a guide column 11 on the fixed mold base 1, and a guide hole 22 on the movable mold base 2. When the fixed mold base 1 and the movable mold base 2 are in a mold closing action, the three molding components respectively drive the molding blocks to extend into the product cavity 20. At the same time, the guide column 11 is movably inserted in the guide hole 22, which plays a guiding effect during the mold closing action, thereby ensuring the quality of the molded product of the die-casting mold.

If the specific posture changes, the directional indication will also change accordingly.
[0040] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
