Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a large-angle inclined top steering core-pulling mechanism of an automobile pillar decorative plate injection mold. Background Art

[0002] Automobile pillar trim panels are generally injection molded by molds. During the injection molding, a hollow snap-in structure needs to be formed at the small-diameter end of the automobile pillar trim panel. The mold in the prior art will provide an insert at the small-diameter end of the pillar trim panel molding cavity, which is inserted into the small-diameter end of the molding cavity. During demolding, the insert is core-pulled through a side core-pulling assembly. However, since the snap-in position is relatively fragile and the connection surface with the lower template is an arc-shaped surface, directly applying a vertical thrust to the snap-in position by straight pushing can easily cause the nearly vertical portion of the connection between the outer side of the snap-in position and the lower template to be damaged due to the pulling force of adhesion with the lower template.

[0003] For example, a Chinese patent discloses an injection mold for an automobile pillar interior panel [application number: 202020801802.3], which includes a lower mold, an upper mold, a fastening edge, a bolt hole, a lifting ear, a groove, a lower mold surface, a connecting hole, a mold depression, a fastening column, an upper mold surface, a mold protrusion, a tightening groove, a snap groove, a support plate groove, a lifting plate, a reinforcing rib groove and a positioning column.

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 5 As shown, a large-angle inclined top and steering core-pulling mechanism of an automobile pillar trim injection mold includes an upper template 1 and a lower template 2. Two pillar trim molding cavities 3 are arranged between the upper template 1 and the lower template 2. The small-diameter end of the pillar trim molding cavity 3 is provided with a small-angle inclined core-pulling component 4 and a large-angle inclined top component 5 corresponding to the small-angle inclined core-pulling component 4. The large-diameter end of the pillar trim molding cavity 3 is provided with a steering core-pulling component 6.

[0028] In the present invention, the pillar trim molding cavity 3 can be injection molded to form the automobile pillar trim, and the small-angle oblique core-pulling component 4 can form an internal hollow snap-in structure at the small-diameter end of the automobile pillar trim. After the mold is opened, the small-angle oblique core-pulling component 4 can realize automatic core pulling. When the product is ejected, the large-angle oblique ejection component 5 can apply an oblique upward thrust to the nearly vertical part of the connection between the outer side of the snap position and the lower template to reduce the shear force caused by adhesion at the snap position, thereby cooperating with the original vertical ejection structure of the mold to achieve the purpose of preventing the snap position from being damaged; secondly, the steering core-pulling component 6 can form a through hole inclined from the inside to the outside on the large-diameter end and can realize automatic core pulling before demolding.

[0029] Specifically, the steering core-pulling assembly 6 includes a No. 1 insert 7 slidably mounted on the upper mold plate 1. The No. 1 insert 7 is arranged obliquely downward and its bottom end is connected to the upper surface of the large-diameter end of the pillar trim molding cavity 3. The bottom end of the No. 1 insert 7 faces the side away from the small-diameter end of the pillar trim molding cavity 3. The steering core-pulling assembly 6 also includes a steering drive assembly connected to the No. 1 insert 7. The No. 1 insert 7 can form a through-hole inclined from the inside to the outside on the large-diameter end of the product during product injection molding. Before mold opening, the steering drive assembly can drive the No. 1 insert 7 to move obliquely upward away from the through-hole to achieve core pulling of the No. 1 insert.

[0030] Specifically, the steering drive assembly includes a No. 1 translation driver 8 horizontally fixed on the upper template 1, and the No. 1 translation driver 8 is vertically arranged to the middle section of the column trim molding cavity 3. The output shaft end of the No. 1 translation driver 8 is fixedly connected to a core-pulling slider 9, and the core-pulling slider 9 is connected to the top of the No. 1 insert 7 through a steering drive structure. The steering drive structure includes a No. 1 push-pull slider 10 obliquely arranged on the inclined surface of the inner end of the core-pulling slider 9. The No. 1 push-pull slider 10 is inserted into the No. 1 push-pull groove 11 obliquely arranged on the inclined surface of the top of the No. 1 insert 7. The cross-sections of the No. 1 push-pull slider 10 and the No. 1 push-pull groove 11 are T-shaped. When the No. 1 push-pull slider 10 moves toward the middle section of the column trim molding cavity 3, the No. 1 insert 7 moves obliquely downward. The No. 1 translation driver 8 can drive the No. 1 push-pull slider 10 to move back and forth in a direction perpendicular to the middle section of the pillar trim panel forming cavity 3. When the No. 1 push-pull slider 10 moves toward the middle section away from the pillar trim panel forming cavity 3, it can drive the No. 1 push-pull slider 10 to move toward the middle section away from the pillar trim panel forming cavity 3. The No. 1 push-pull slider 10 with a T-shaped cross-section moves toward the middle section away from the pillar trim panel forming cavity 3 and cooperates with the No. 1 push-pull groove 11 with a T-shaped cross-section to pull the No. 1 insert 7 to move obliquely upward to disengage the No. 1 insert from the through hole.

[0031] Those skilled in the art should understand that the first translation driver may be an oil cylinder, an air cylinder or a linear motor, etc.

[0032] Specifically, a second push-pull chute 12 is vertically provided on the inclined surface at the inner end of the core-pulling slider 9 and runs through it from top to bottom. The second push-pull chute 12 is perpendicularly arranged with the first push-pull slider 10. The second push-pull slider 13 with a T-shaped cross section is integrally formed on the side of the first push-pull slider 10 away from the first insert 7. The second push-pull slider 13 is inserted into the second push-pull chute 12. The first push-pull slider 10 is connected to the second push-pull chute 12 on the core-pulling slider 9 through the second push-pull slider 13, which facilitates the quick removal of the first push-pull slider 10.

[0033] Specifically, combined Figure 2-Figure 5 As shown, the small-angle oblique core-pulling assembly 4 includes an obliquely arranged inclined slide 14, the angle between the bottom surface of the inclined slide 14 and the horizontal plane is an acute angle, the inner end of the inclined slide 14 is fixedly connected to a No. 2 insert 15 parallel to the bottom surface of the inclined slide 14, the inner end of the No. 2 insert 15 is against the small diameter end of the column trim molding cavity 3, and the upper template 1 is also fixedly connected to a drive rod 16 arranged obliquely, the drive rod 16 is inserted into the inclined slide 14 and slidably cooperates with the inclined slide 14. The No. 2 insert 15 is inserted into the small diameter end of the column trim molding cavity 3 to form a hollow groove body with a snap-fit structure at the small diameter end of the column trim. When the mold is opened, the upper template 1 moves upward to drive the drive rod to move vertically upward, and the vertical upward movement of the drive rod can drive the inclined slide 14 and the No. 2 insert to move obliquely downward away from the small diameter end of the column trim, thereby realizing automatic core pulling of the No. 2 insert.

[0034] Specifically, the high-angle ejector assembly 5 includes an ejector insert 17 that slidably engages the lower mold plate 2. The ejector insert 17 is tilted and formed at an obtuse angle with the horizontal plane. A buckle-forming gap 18 is formed between the top of the ejector insert 17 and the lower surface of the inner end of the second insert 15. The high-angle ejector assembly 5 also includes an ejector drive assembly connected to the ejector insert 17. During product ejection, the ejector drive assembly drives the ejector insert 17 to apply an oblique upward thrust to the buckle at the buckle-forming gap 18, thereby reducing shear forces on the buckle caused by adhesion and preventing damage to the buckle during ejection.

[0035] Specifically, the inclined top drive assembly includes a No. 2 translational actuator 19 fixed to the lower mold plate 2. The output shaft end of the No. 2 translational actuator 19 is fixedly connected to a horizontally arranged inclined top slider 20. The inclined top slider 20 is connected to the inclined top insert 17 via an inclined guide structure. The inclined guide structure includes a No. 3 push-pull slider 21 tilted on the inclined surface of the inner end of the inclined top slider 20. The No. 3 push-pull slider 21 is inserted into a No. 3 push-pull slot 22 set on the inclined surface of the bottom end of the inclined top insert 17. The No. 3 push-pull slider 21 and the No. 3 push-pull slot 22 have a T-shaped cross-section. When the inclined top slider 20 moves toward the column trim molding cavity 3, the inclined top insert 17 moves diagonally upward. The No. 2 translational actuator 19 can drive the inclined top slider 20 to penetrate horizontally. When the inclined top slider 20 moves toward the column trim molding cavity 3, the No. 3 push-pull slider 21 cooperates with the No. 3 push-pull slot 22 to drive the inclined top insert 17 diagonally upward.

[0036] Those skilled in the art should understand that the second translation driver 19 can be an oil cylinder, an air cylinder or a linear motor, etc.

[0037] The working principle of the present invention is as follows: the pillar trim molding cavity 3 can be injection molded to form the automobile pillar trim, and the small-angle oblique core-pulling component 4 can form an internal hollow buckle structure at the small-diameter end of the automobile pillar trim. After the mold is opened, the small-angle oblique core-pulling component 4 can realize automatic core pulling. When the product is ejected, the large-angle oblique ejection component 5 can apply an oblique upward thrust to the nearly vertical part of the connection between the outer side of the buckle position and the lower template to reduce the shear force caused by adhesion at the buckle position, thereby cooperating with the original vertical ejection structure of the mold to prevent the buckle position from being damaged; secondly, the steering core-pulling component 6 can form a through hole inclined from the inside to the outside on the large-diameter end and can realize automatic core pulling before demolding;

[0038] When the first push-pull slider 10 is moved away from the middle section of the column trim panel forming cavity 3, it can drive the first push-pull slider 10 to move in the direction away from the middle section of the column trim panel forming cavity 3. When the first push-pull slider 10 is moved away from the middle section of the column trim panel forming cavity 3, the first push-pull slider 10 with a T-shaped cross-section moves in the direction away from the middle section of the column trim panel forming cavity 3. The first push-pull slide groove 11 with a T-shaped cross-section can pull the first insert 7 to move obliquely upward to separate the first insert from the through-hole. The first push-pull slider 10 is connected to the second push-pull slide groove 12 on the core-pulling slider 9 through the second push-pull slider 13, which can facilitate the quick disassembly of the first push-pull slider 10.

[0039] The second insert 15 is inserted into the small-diameter end of the column trim molding cavity 3 to form a hollow groove body with a snap-fit structure at the small-diameter end of the column trim. When the mold is opened, the upper template 1 moves upward to drive the driving rod to move vertically upward. The vertical upward movement of the driving rod can drive the inclined slide 14 and the second insert to move obliquely downward away from the small-diameter end of the column trim, thereby realizing automatic core pulling of the second insert;

[0040] When the product is ejected, the inclined top drive assembly can drive the inclined top insert 17 to apply an oblique upward thrust to the buckle at the buckle molding gap 18 to reduce the shear force caused by adhesion at the buckle position, thereby preventing the buckle part from being damaged during ejection. The No. 2 translation driver 19 can drive the inclined top slider 20 to penetrate in the horizontal direction. When the inclined top slider 20 moves toward the direction close to the column trim molding cavity 3, it can drive the inclined top insert 17 to move obliquely upward through the No. 3 push-pull slider 21 and the No. 3 push-pull slot 22.
