Description

Technical Field

[0001] The invention belongs to the technical field of molds, and in particular relates to a combined spring block structure for obliquely inserting a mold core. Background Art

[0002] The spring block is a common core-pulling structure used to solve the undercut problem of the product, and is usually installed on the fixed mold side. The traditional single spring block core-pulling structure is generally used to solve the undercut problem of the vertically installed mold core, but due to product requirements and mold cost considerations, the mold core often needs to be designed in an oblique manner, so undercuts will also be added to the mold core, making it difficult to directly use a single spring block on the mold.

[0003] The design of the above-mentioned oblique mold core requires that all interfering parts on the mold frame be avoided on the installation path of the mold core, and in order to facilitate the installation of the spring block structure, the mold core undercut position must also be completely cut off, so that the spring block structure does not have sufficient support, causing structural failure. At the same time, when the traditional single core-pulling spring block structure is used on the mirrored headlight mold, two sets of mirrored structures need to be designed to complete the core-pulling action, resulting in an increase in mold size and a significant increase in mold cost. Summary of the invention

[0004] The purpose of the present invention is to solve the defects and shortcomings existing in the prior art and to provide a combined spring block structure for obliquely inserted mold cores, which not only solves the problem of difficulty in core pulling of obliquely inserted mold cores, but also the combined structural design can reduce the overall size of the mold, thereby effectively controlling the mold cost.

If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0036] like Figure 1-4As shown, the present invention provides a combined spring block structure for obliquely inserting mold cores, including a spring block body 1, a spring block guide block 2, a T-shaped guide, an equal height screw 4, a spring 5 and an oblique wedge 6. The spring block body 1 has two, and the left and right mirror images are distributed. Since the combined spring block structure is subjected to twice the force of a single spring block structure during operation, the design requirements of the spring block guide block 2 are relatively high. The spring block guide block 2 is arranged between the two spring block bodies 1, and is used to guide the two spring block bodies 1 to move upward along their left and right sides respectively to complete the release action. Specifically, the spring block guide block 2 is provided with a spring block fixed to the mold frame. The screw holes for connection are provided at the bottom, and the first boss 7 which is installed in cooperation with the mold frame is provided. The two adjacent side surfaces of the first boss 7 are straight surfaces, and the other two adjacent side surfaces of the first boss 7 are inclined surfaces, and the inclined surface angle is 3°. At the same time, in order to ensure the stability of the structure, the four side surfaces of the front, back, left and right of the spring block guide block 2 are all inclined surface designs, and the inclined surface angle is 3°, wherein the front and back side surfaces are respectively matched with the inclined wedge 6 and the mold frame, and a T-block 3 is provided at the center position of the left and right side surfaces of the spring block guide block 2. The inclination angle of the T-block 3 is 2° smaller than the inclination angle of the left and right side surfaces of the spring block guide block 2, so as to prevent the spring block from getting stuck during movement.

[0037] The mirror-image-arranged headlight mold requires the structure to be cored at the same time, so the present invention adopts two bullet bodies 1 distributed in left and right mirror images to reduce the product arrangement. The bullet body 1 is designed on both sides of the bullet guide block 2, which saves mold space and greatly reduces mold cost. In order to meet the requirement of simultaneous movement, the combined bullet structure is provided with a second boss 8 on the side of the bullet body 1 away from the bullet guide block 2. The side of the second boss 8 is inclined, and the inclination angle is 3°, which is convenient for repair. The side of the bullet body 1 close to the bullet guide block 2 is provided with a T-slot that slides with the T-block 3, and the bullet body 1 is provided with equal height screws 4 and springs 5. The bullet body 1 can slide upward along the T-block 3 under the action of the equal height screws 4 and springs 5. The calculation formula of the movement stroke of the bullet body 1 is as follows: L 弹块水平运动距离 =S 弹簧行程 ×sinα, where α is the angle of the bullet body 1.

[0038] At the same time, the mold core is an obliquely inlaid structure, so it is necessary to avoid all the interfering parts on the mold frame on the installation path of the mold core, and in order to facilitate the installation of the spring block structure, it is also necessary to cut off all the inverted positions of the mold core, so that the spring block structure does not have sufficient support, resulting in the failure of the structure. Therefore, the design of the composite spring block structure cannot be without the side bevel 6, which is matched with the end of the spring block guide block 2 to provide support for the spring block body 1. The side of the bevel 6 close to the spring block body 1 is inclined with an inclination angle of 3°, and the other sides are all straight faces. The bottom of the bevel 6 is provided with a third boss 9 that is installed in cooperation with the mold frame. The two adjacent side surfaces of the third boss 9 are straight faces, and the other two adjacent side surfaces of the third boss 9 are inclined faces.

[0039] The present invention discloses a combined spring block structure for obliquely inserted mold cores, which is applied to the undercut area of ​​the fixed mold of the obliquely inserted mold core. The obliquely inserted mold core needs to be installed vertically along the installation path, so the excess iron on the mold frame needs to be avoided. At the same time, in order to facilitate the installation of the spring block structure, the undercut position of the mold core also needs to be completely cut off.

[0040] Next is the combined spring block structure. The inclined wedge 6 supporting the side of the spring block body 1 is installed from the front. Due to the oblique mold core, the iron on the side wall of the spring block body 1 is completely hollowed out. Therefore, the stability of the structure supporting the spring block body 1 is required. The inclination angle of the inclined wedge 6 close to the side of the spring block body 1 is 3°, which is consistent with the side of the spring block body 1. Then the spring block guide 2 is repaired and assembled. Since the force received by the combined spring block structure during operation is twice that of the single spring block structure, two straight and two oblique repair first bosses 7 are designed on the bottom surface, and two screws are designed on the front to fix it. Then the T-block 3 is installed. To prevent the structure from getting stuck, the angle of the T-block 3 and the T-slot is 2° smaller than the inclined surface of the spring guide block 2. Then the mirrored spring block body 1 is installed. The second boss 8 needs to be repaired first to ensure that the mirrored spring block body 1 can be disengaged at the same time. The equal height screws 4 and spring 5 can be installed at the same time with the spring block body 1.

[0041] When the mold is opened, under the action of the spring 5, the left and right mirror-image spring block body 1, relying on the support of the side inclined wedge 6 and the mold frame, moves upward along the spring block guide block 2 to complete the release action.

[0042] The combined spring block structure for the obliquely inserted mold core provided by the present invention can not only solve the problem of difficult core pulling of the obliquely inserted mold core, but also reduce the mold size and mold cost; at the same time, the structure can be reused on the same type of mold with significant effect.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
