[0050] The present invention provides a multi-stage slider demolding device 100.

[0051] As Figures 1 to 2As shown in the figure, a multi-stage slider demolding device 100 includes: a rear mold core 10, on which a first plastic surface A and a second plastic surface B are provided. The first plastic surface A and the second plastic surface B are arranged at an angle. A contact surface C is horizontally arranged on the rear mold core 10. Both the first plastic surface A and the second plastic surface B are arranged at an angle with the contact surface C; a first slider 20, which is slidably arranged on the contact surface C. One end of the first slider 20 facing the first plastic surface A forms a first mold cavity with the first plastic surface A; a second slider 30, which penetrates through the first slider 20 and is slidably connected to the first slider 20. One side of the second slider 30 facing the rear mold core 10 forms a second mold cavity with the second plastic surface B; a demolding assembly 40, which penetrates through the first slider 20. A first inclined surface D is provided on the demolding assembly 40. The first inclined surface D is perpendicular to the contact surface C. The second slider 30 is slidably connected to the first inclined surface D. The second slider 30 can move closer to or away from the second plastic surface B relative to the demolding assembly 40; wherein, when the demolding assembly 40 moves away from the first plastic surface A relative to the second slider 30, the longer the distance between the demolding assembly 40 and the first plastic surface A, the shorter the distance from the first inclined surface D to the second plastic surface B. When the demolding assembly 40 moves away from the rear mold core 10, the second slider 30 moves away from the second plastic surface B. After that, when the first slider 20 moves away from the rear mold core 10, the first slider 20 moves away from the first plastic surface A.

[0052] In this embodiment, a first plastic surface A and a second plastic surface B are provided on the rear mold core 10. The first plastic surface A and the second plastic surface B are arranged at an angle. And ribs (or deep ribs) are formed on the first plastic surface A and / or the second plastic surface B. The first slider 20 is slidably arranged on the rear mold core 10. The plane where the first slider 20 slides with the rear mold core 10 is the abutting surface C, and the abutting surface C is a horizontal plane. Both the first plastic surface A and the second plastic surface B are arranged at an angle with the abutting surface C. For example, both the first plastic surface A and the second plastic surface B are perpendicular to the abutting surface C. After the first slider 20 is installed on the abutting surface C, one end of the first slider 20 facing the first plastic surface A forms a first mold cavity with the first plastic surface A. Injection mold grooves and the like for injection molding can be arranged at one end of the first slider 20 facing the first plastic surface A. And the second slider 30 penetrates through the first slider 20. One end of the second slider 30 facing the rear mold core 10 extends partially outside the first slider 20. And one side of the second slider 30 facing the rear mold core 10 forms a second mold cavity with the second plastic surface B. The first mold cavity and the second mold cavity can be communicated or independent of each other. Of course, injection mold grooves and the like for injection molding can also be arranged on the side surface of the second slider 30 facing the rear mold core 10. To form a complete injection mold cavity, a mold closing part (not shown in the figure) is also required. Injection mold grooves are also provided on the surface of the mold closing part. The mold closing part, the rear mold core 10, the first slider 20 and the second slider 30 are assembled to realize the mold closing of the entire injection mold and form a complete injection mold cavity. After injecting the injection liquid with strong pressure, the injection liquid fills the injection mold cavity. Rib structures or deep rib structures of the product are formed in both the first mold cavity and the second mold cavity and are integrally formed with the product in the injection mold cavity. After the products are all cooled, the mold closing part is opened for demolding operation. During this process, in order to reduce the core-pulling demolding process, the present invention adopts a demolding assembly 40. The demolding assembly 40 also penetrates through the first slider 20 and is slidably connected with the first slider 20. A first inclined surface D is provided on the demolding assembly 40. The first inclined surface D is perpendicular to the abutting surface C. The second slider 30 is slidably arranged on the first inclined surface D. In order to realize two-way demolding, the second slider 30 can be slidably arranged relative to the demolding assembly 40. When the demolding assembly 40 moves away from the rear mold core 10, it drives the second slider 30 to move away from the second plastic surface B. Among them, the inclination direction of the first inclined surface D is the same as the direction in which the second slider 30 moves away from the second plastic surface B. That is, in the sliding direction of the demolding assembly 40 moving away from the rear mold core 10, the demolding assembly 40 moves away from the first inclined surface A, and the longer the distance from the first plastic surface A, the shorter the distance between the first inclined surface D and the second plastic surface B. Therefore, during the process of the demolding assembly 40 moving away from the rear mold core 10 (the sliding direction is as Figure 2In the F0 direction in it), the demolding assembly 40 gradually withdraws the first slider 20, and a demolding area is generated between the demolding assembly 40 and the first slider 20 (the demolding area is the original assembly position of the demolding assembly 40 on the first slider 20), so that the second slider 30 slides along the first inclined surface D. The sliding direction of the second slider 30 is perpendicular to the sliding direction of the demolding assembly 40, so that the second slider 30 continuously moves towards the demolding area, and the second slider 30 gradually moves away from the second glue surface B (the sliding direction is as Figure 2 the F1 direction in it), until the product in the second mold cavity is demolded, and then the first slider 20 is driven away from the rear mold core 10 until the product in the first mold cavity is demolded.

[0053] Therefore, in the present invention, the second slider 30 is slidably arranged on the first inclined surface D, and the second slider 30 can move away from the second glue surface B relative to the demolding assembly 40, realizing lateral (hereinafter referred to as the first direction) demolding. After the product in the second mold cavity is demolded, the first slider 20 is driven away from the rear mold core 10 to demold the product in the first mold cavity, realizing vertical (hereinafter referred to as the second direction) demolding. The linkage of multiple groups of sliders realizes multi-directional demolding, reduces the core-pulling demolding process, and also reduces the cost of the production mold.

[0054] As Figures 3 to 6 shown, specifically, one of the second slider 30 and the first inclined surface D is provided with a first chute E, and the other is provided with a first protrusion 4211. The first protrusion 4211 is arranged in the first chute E, and the first chute E is arranged along the sliding direction of the demolding assembly 40. In this embodiment, a first chute E can be opened on the second slider 30. Correspondingly, a first protrusion 4211 is arranged on the first inclined surface D. The first protrusion 4211 is slidably arranged in the first chute E to ensure that the second slider 30 is always connected to the demolding assembly 40, and as the demolding assembly 40 slides in the second direction, the second slider 30 moves away from the second glue surface B relative to the demolding assembly 40.

[0055] Specifically, the cross-section of the first protrusion 4211 is T-shaped. As an optional embodiment, the cross-section of the first protrusion 4211 is T-shaped. The plane where the cross-section is located is perpendicular to the abutting surface C and is arranged at an angle with the first inclined surface D, so that the first protrusion 4211 can only slide along the length direction of the first chute E to ensure that the second slider 30 is always slidably connected to the first inclined surface D.

[0056] Specifically, a limiting groove F is formed in the second slider 30. The limiting groove F is arranged along the sliding direction of the second slider 30. The multi-stage slider demolding device 100 further includes a limiting member 50. The limiting member 50 penetrates through the first slider 20 and extends into the limiting groove F. When the second slider 30 approaches or moves away from the second glue surface B relative to the demolding assembly 40, the limiting member 50 is always in sliding connection with the groove wall of the limiting groove F. In this embodiment, in order to define the sliding direction of the second slider 30, a limiting groove F can be formed in the second slider 30. The limiting groove F is arranged along the sliding direction of the second slider 30 (the sliding direction is, for example, Figure 2 the F1 direction in

[0057] ), and a limiting member 50 is added. The length direction of the limiting member 50 is perpendicular to the abutting surface C. The limiting member 50 penetrates through the first slider 20 and extends into the limiting groove F, so that the limiting member 50 can be fixedly arranged with the first slider 20. When the second slider 30 approaches or moves away from the second glue surface B relative to the demolding assembly 40, the limiting member 50 is always in sliding connection with the groove wall of the limiting groove F, thus defining the sliding direction of the second slider 30.

[0058] Specifically, the demolding assembly 40 includes two guiding members 41 which are arranged on the first slider 20 at intervals; a demolding mechanism 42. A first inclined surface D is arranged on the demolding mechanism 42. The side of the demolding mechanism 42 away from the rear mold core 10 is located between the two guiding members 41. When the demolding mechanism 42 moves away from the rear mold core 10, the second slider 30 moves along the first chute E and away from the second glue surface B relative to the demolding mechanism 42. In this embodiment, in order to define the sliding direction of the demolding assembly 40, two guiding members 41 can be arranged on the first slider 20 at intervals. The length direction of the guiding members 41 is consistent with the sliding direction of the demolding mechanism 42. The side of the demolding mechanism 42 away from the rear mold core 10 is located between the two guiding members 41, and the two symmetric surfaces of the demolding mechanism 42 are respectively abutted against the corresponding guiding members 41. During the sliding process of the demolding mechanism 42, the demolding mechanism 42 will not be displaced.

[0058] Specifically, the demolding mechanism 42 includes: a third slider 421 that penetrates through the first slider 20. A first inclined surface D is provided on the third slider 421, and an adjustment hole G is also provided on the third slider 421; an adjustment rod 422 is inserted into the adjustment hole G. The adjustment rod 422 is inclined towards the rear mold core 10 and is arranged at an angle with the abutting surface C. Wherein, when the adjustment rod 422 moves vertically upward relative to the abutting surface C, the third slider 421 is forced to move away from the rear mold core 10. In this embodiment, the demolding mechanism 42 mainly includes a third slider 421 and an adjustment rod 422. Among them, the third slider 421 penetrates through the first slider 20, and a first inclined surface D is provided on the third slider 421. The second slider 30 is slidably connected to the third slider 421 through the first inclined surface D. An adjustment hole G is also formed on the third slider 421. The adjustment hole G can penetrate through the third slider 421. The adjustment hole G is inclined. The adjustment rod 422 is inserted into the adjustment hole G. The adjustment rod 422 is inclined towards the rear mold core 10, and the adjustment rod 422 is arranged at an angle with the abutting surface C. When the adjustment rod 422 moves vertically upward relative to the abutting surface C, the adjustment rod 422 moves away from the adjustment hole G. The outer wall of the adjustment rod 422 continuously rubs against the hole wall of the adjustment hole G, causing the third slider 421 to generate a force away from the rear mold core 10, driving the third slider 421 away from the rear mold core 10.

[0059] Specifically, an oil groove H is provided on the surface of the third slider 421, and the oil groove H is used for storing lubricating oil. In this embodiment, in order to improve the sliding efficiency of the third slider 421, an oil groove H can be formed on the surface of the third slider 421 to facilitate adding machine oil into the oil groove H, improving the lubrication degree between the third slider 421 and other components and improving the demolding efficiency.

[0060] Specifically, the multi-stage slider demolding device 100 further includes: a fixing member 60, which is connected to the end of the adjusting rod 422 away from the second slider 30; a shovel base 70, on which a first second inclined surface is provided, the first second inclined surface is inclined towards the rear mold core 10, and the inclination angle of the first second inclined surface is the same as that of the adjusting rod 422. The side of the third slider 421 away from the rear mold core 10 is slidably connected to the first second inclined surface, and the shovel base 70 is relatively fixed to the fixing member 60; wherein, after demolding, when the adjusting rod 422 and the shovel base 70 move vertically downward relative to the abutting surface C, both the adjusting rod 422 and the shovel base 70 drive the second slider 30 to approach the rear mold core 10. In this embodiment, a fixing member 60 can be provided at the end of the adjusting rod 422 away from the second slider 30, and a shovel base 70 can be provided on the side of the third slider 421 away from the rear mold core 10. The shovel base 70 is relatively fixed to the fixing member 60, and the two move synchronously. A first second inclined surface is also provided on the shovel base 70, and the first second inclined surface also inclines towards the rear mold core 10, and the inclination angle of the first second inclined surface is the same as that of the adjusting rod 422. During demolding, the shovel base 70 and the fixing member 60 move upward synchronously relative to the abutting surface C. At this time, the fixing member 60 drives the adjusting rod 422 away from the third slider 421, and the third slider 421 is forced to move away from the rear mold core 10; after demolding, the shovel base 70 and the fixing member 60 move downward synchronously relative to the abutting surface C, the adjusting rod 422 drives the third slider 421 to be forced to approach the rear mold core 10, and the first second inclined surface assembly of the shovel base 70 abuts against the third slider 421 and fixes the third slider 421 to prevent the position of the third slider 421 from shifting.

[0061] Specifically, a wear-resistant member 80 is provided on the side of the third slider 421 away from the rear mold core 10; wherein, when the side of the third slider 421 away from the rear mold core 10 is slidably connected to the first second inclined surface, the wear-resistant member 80 abuts against the first second inclined surface. In this embodiment, in order to improve the service life of the third slider 421, a wear-resistant member 80 can be provided on the side of the third slider 421 away from the rear mold core 10, and the wear-resistant member 80 abuts against the first second inclined surface to prevent the third slider 421 from being damaged by friction.

[0062] Specifically, an adjustment groove K penetrating the first slider 20 is provided on one side of the first slider 20 away from the rear mold core 10. The multi-stage slider demolding device 100 further includes: a tapered guide pin 90, which includes a vertical portion 91 and an inclined portion 92. The vertical portion 91 is disposed in the adjustment groove K. The inclined direction of the inclined portion 92 is the same as the inclined direction of the adjusting rod 422. The vertical portion 91 is relatively fixed to the lifter base 70. Wherein, when the tapered guide pin 90 moves upward, the lifter base 70 and the fixing member 60 move upward synchronously, driving the third slider 421 away from the rear mold core 10. When the inclined portion 92 enters the adjustment groove K, the first slider 20 abuts against the inclined portion 92 and slides under force. The sliding direction of the first slider 20 is the same as the sliding direction of the third slider 421. In this embodiment, in order to reduce the demolding process, an adjustment groove K penetrating the first slider 20 can be provided on one side of the first slider 20 away from the rear mold core 10, and a tapered guide pin 90 having a vertical portion 91 and an inclined portion 92 is provided. Among them, the vertical portion 91 is relatively fixed to the fixing member 60, and the vertical portion 91 is disposed in the adjustment groove K. The inclined direction of the inclined portion 92 is the same as the inclined direction of the adjusting rod 422, and the height of the vertical portion 91 is less than the height of the inclined portion 92. The vertical portion 91 of the tapered guide pin 90 serves as a driving component for demolding the second glue surface B. When demolding the second glue surface B, the tapered guide pin 90 moves upward, and the vertical portion 91 drives the lifter base 70 and the fixing member 60 to move upward synchronously. The adjusting rod 422 is driven by force to drive the third slider 421 away from the rear mold core 10 until the second glue surface B is demolded. However, the product located in the first mold cavity has not been demolded yet. At this time, the inclined portion 92 is driven to continue to displace into the adjustment groove K until the inclined portion 92 abuts against the groove wall of the adjustment groove K. Since the inclined direction of the inclined portion 92 is the same as the inclined direction of the adjusting rod 422, the first slider 20 slides under force, and the sliding direction of the first slider 20 is the same as the sliding direction of the third slider 421, so that the first slider 20 is separated from the rear mold core 10, realizing the demolding of the first glue surface A.

[0063] The present invention provides an automotive functional part mold, including the multi-stage slider demolding device 100 described in any one of the above, and a bottom plate (not shown in the figure); a driving component (not shown in the figure), the driving component is disposed on the bottom plate, and the driving component is fixedly connected to the demolding component 40.
