[0027] Specifically, the die-casting mold has a movable mold assembly and a fixed mold assembly. The movable mold assembly is provided with a movable mold core plate, and the fixed mold assembly is provided with a fixed mold cavity plate. The movable mold assembly can move relative to the fixed mold assembly to achieve mold closing and opening. The sliding assembly 1 has a slider 100 and a first slide 101 that are connected to each other. The first slide 101 is connected to an externally arranged driving cylinder, so that the first slide 101 drives the slider 100 to move through the driving cylinder, and the core pulling assembly 2 is obliquely arranged below the sliding assembly 1. The core pulling assembly 2 has a core pulling rod 200 and a second slide 201, and the first slide 101 is movably connected to the second slide 201. When a die-cast product is needed, the movable mold assembly will move toward the fixed mold assembly, and the movable mold core plate and the fixed mold core plate will be abutted against each other. Then, the driving cylinder arranged on the movable mold assembly will drive the first slide 101 to move and the slider 100 connected to the first slide 101 to move to a preset position. At this time, the first slide 101 can drive the second slide 201 to move, so that the second slide 201 drives the core pulling rod 200 to move at an angle relative to the slider 100, which can ensure the stable movement of the sliding assembly 1 and the core pulling assembly 2 and achieve a one-to-two effect. The movable mold core plate, the fixed mold cavity plate, the slider 100 and the core pulling rod 200 form a product cavity, and the required product can be cast and formed in the product cavity with ease, thereby ensuring the quality of the product.

[0028] Specifically, Figures 1 to 5 The sliding assembly 1 has a pair of first guide blocks 102, which are located on both sides of the first slide 101, and the lower end of the first slide 101 is detachably connected with a guide block 103, which is located between the pair of first guide blocks 102 and movably connected to the second slide 201.

[0029] The first guide block 102 is used to guide the movement of the first slide 101, ensuring that the slider 100 with the first slide 101 can stably move to a preset position when the mold is closed, thereby ensuring the quality of the product after die-casting. The guide block 103 helps the first slide 101 to move to the preset position, and can drive the core pulling rod 200 to move, achieving a one-to-two effect.

[0030] Furthermore, if Figures 3 to 5 As shown, a first inclined wedge portion 104 is provided below the guide block 103, a second inclined wedge portion 105 is provided at the end of the guide block 103 close to the slider 100, a groove 202 is provided on the second slide seat 201, the guide block 103 moves in the groove 202, a third inclined wedge portion 203 is provided at the end of the groove 202 away from the core pulling rod 200, a fourth inclined wedge portion 204 is provided at the end of the groove 202 close to the core pulling rod 200, the first inclined wedge portion 104 is slidably connected to the third inclined wedge portion 203, and the second inclined wedge portion 105 is slidably connected to the fourth inclined wedge portion 204.

[0031] The lower end of the first slide 101 is connected to the guide block 103 by bolts, and the guide block 103 is located in the groove 202. When the mold is opened, the externally arranged driving cylinder will pull the first slide 101 and the slider 100 to move outward. When the first slide 101 moves, the guide block 103 will also move synchronously until the first inclined wedge portion 104 of the guide block 103 abuts against the third inclined wedge portion 203 arranged at the end of the groove 202 away from the core pulling rod 200 (that is, the first slide 101 moves to the preset position). When the first slide 101 continues to move outward, the first inclined wedge portion 104 will abut against the third inclined wedge portion 203, and the inclined wedge surface on the first inclined wedge portion 104 and the inclined wedge surface of the third inclined wedge portion 203 slide and cooperate, so that the second slide 201 located below the slider 100 in an inclined state drives the core pulling rod 200 to move outward synchronously; when the mold is closed. , the externally arranged driving cylinder will push the first slide 101 and the slider 100 to move inwardly. When the first slide 101 moves, the guide block 103 will also move synchronously, and the guide block 103 moves in the groove 202 until the second bevel portion 105 of the guide block 103 abuts against the fourth bevel portion 204 provided at the end of the groove 202 close to the core pulling rod 200 (that is, the first slide 101 moves to the preset position). When the first slide 101 continues to move inwardly, the second bevel portion 105 will abut against the fourth bevel portion 204, and the bevel surface on the second bevel portion 105 and the bevel surface of the fourth bevel portion 204 are slidably matched, so that the second slide 201 located in an inclined state below the slider 100 drives the core pulling rod 200 to move inward synchronously, so that the movable model core plate, the fixed model cavity plate, the slider 100 and the core pulling rod 200 are enclosed to form a product cavity.

[0032] Furthermore, if Figure 2 , Figure 4 as well as Figure 6 As shown, the core pulling assembly 2 has a pair of second guide blocks 205, and the pair of second guide blocks 205 are inclinedly arranged below the first slide 101, and one of the second guide blocks 205 is connected to a first guide block 102 on the same side, the second slide 201 is located between the pair of second guide blocks 205, and guide portions 206 are provided on both sides of the second slide 201, and guide grooves 207 are opened on the ends of the pair of second guide blocks 205 close to each other, and the guide portions 206 are slidably connected to the guide grooves 207.

[0033] The guide portion 206 of the second guide block 205 is slidably connected to the guide groove 207 of the second guide block 205, which can provide guidance for the movement of the second slider 100, ensure that the core pulling rod 200 can be in a preset position in the product cavity, and ensure the quality of the product formed by subsequent die casting.

[0034] Furthermore, if Figure 6As shown, a clamping groove 208 is provided on the end of the second slide seat 201 close to the fourth inclined wedge portion 204 , and a clamping head 209 is provided on the core pulling rod 200 , and the clamping head 209 is clamped with the clamping groove 208 .

[0035] One end of the core pulling rod 200 is used for forming the side hole of the product, and the other end of the core pulling rod 200 is provided with a clamping head 209, which is detachably clamped with the clamping slot 208. The core pulling rod 200 will be damaged under long-term use, so that the operator can inspect and replace the core pulling rod 200 later.

[0036] Furthermore, if Figure 6 As shown, the core pulling assembly 2 has a fixed block 210 , and a pair of second guide blocks 205 are connected to the fixed block 210 at the ends close to the core pulling rod 200 , and the core pulling rod 200 movably passes through the fixed block 210 .

[0037] The fixing block 210 can further help the core pulling rod 200 to be better fixed on the second slide 201, so that the core pulling rod 200 can stably perform core pulling.

[0038] Furthermore, if Figure 4 and Figure 6 As shown, a sleeve 211 is provided on the end of the fixing block 210 away from the second guide block 205 , and the sleeve 211 is sleeved on the core pulling rod 200 .

[0039] The sleeve 211 is sleeved on the outer side of the core pulling rod 200 to protect the core pulling rod 200 and also guide the core pulling rod 200 to effectively prevent the core pulling rod 200 from being damaged, thereby extending the service life of the core pulling rod 200.

[0040] Furthermore, if Figure 1 , Figure 5 as well as Figure 6 As shown, an oblique groove 106 is formed at the lower end of the slider 100 , and an oblique convex portion 212 is formed on the fixing block 210 , and the oblique groove 106 is slidably connected to the oblique convex portion 212 .

[0041] When the external driving cylinder drives the first slide 101 to move and the slider 100 connected to the first slide 101 moves to a preset position, the first slide 101 can drive the second slide 201 to move. An inclined groove 106 is provided at the lower end of the slider 100, and an inclined convex portion 212 is correspondingly formed on the fixed block 210. The inclined groove 106 is slidably connected with the inclined convex portion 212 to ensure that the slider 100 does not collide with the fixed block 210 during movement, and to ensure that no interference occurs during the one-to-two process.
