Description

Technical Field

[0001] This utility model relates to the field of automotive rearview mirror demolding technology, specifically to a composite core-pulling structure for automotive rearview mirrors with straight and angled tops. Background Technology

[0002] Car rearview mirrors are located on the left and right sides of the front of the car, as well as in the front of the interior. They reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas. They act as a "second eye," expanding the driver's field of vision.

[0003] Currently, existing car rearview mirror products have their edges turned upside down after injection molding, such as... Figure 5 As shown in section B, the screw-fixed column makes vertical demolding impossible, thus requiring a composite core-pulling structure for automotive rearview mirrors with straight and angled tops. Utility Model Content

[0004] The purpose of this utility model is to provide a composite core-pulling structure for automotive rearview mirrors with straight and angled tops, in order to solve the problem mentioned in the background art where the product's perimeter is flanged and undercut, and the screw fixing posts prevent vertical demolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite core-pulling structure for a car rearview mirror, comprising a base plate, on the surface of which a lower ejector plate, a middle ejector plate, and an upper ejector plate are respectively placed from bottom to top. A B plate is provided above the base plate, and a rear mold core is installed inside the B plate. A slanted and straight ejector mechanism is provided between the rear mold core and the base plate, which sequentially penetrates the B plate, the upper ejector plate, the middle ejector plate, and the lower ejector plate. This slanted and straight ejector mechanism is used for composite core-pulling of the product.

[0006] Preferably, square irons are bolted to both sides of the base plate surface, and the top of the square irons is fixed to the bottom of the B plate.

[0007] Preferably, the rear mold core is internally injection molded with a car rearview mirror product, and the inclined straight ejector mechanism is used to eject the injection-molded car rearview mirror product.

[0008] Preferably, the inclined straight-push mechanism includes a straight-push block, an inclined-push block, a straight-push rod, an inclined-push rod, an inclined-push universal seat, and a 90° universal water nozzle, wherein the inclined-push universal seat is fixed to the interior of the middle ejector plate and the lower ejector plate.

[0009] Preferably, the inclined ejector universal seat has two movable inclined ejector rods installed inside at an angle, and the bottom end of the inclined ejector rods passes through the inclined ejector universal seat and extends to the interior of the base plate and is equipped with a 90° universal water nozzle. The output end of the inclined ejector universal seat passes through the upper ejector plate and the B plate in sequence, extends to the interior of the rear mold core, and is equipped with an inclined ejector block. The inclined ejector block is used for the inclined ejection operation of the automotive rearview mirror product.

[0010] Preferably, two straight ejector rods are vertically mounted on the surface of the lower ejector plate by bolts, and the top of the straight ejector rods extends through the middle ejector plate, the upper ejector plate and the B plate in sequence to the interior of the rear mold core and is equipped with a straight ejector block. The straight ejector block is used for the straight ejection operation of the automotive rearview mirror product.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This automotive rearview mirror straight-top and angled-top composite core-pulling structure uses an angled-straight-top mechanism; when the product structure is limited and a through-type angled top cannot be designed, a middle ejector plate is used to achieve demolding. The upper ejector plate, middle ejector plate, and lower ejector plate form a combined secondary ejection system. The straight ejector block and the angled ejector block are fixed to the lower ejector plate by angled ejector blocks and angled ejector rods, respectively. When the upper ejector plate, middle ejector plate, and lower ejector plate move upward, the straight ejector block and the angled ejector block also move upward synchronously. The straight ejector block moves upward in a straight line, and the angled ejector block moves upward while also moving laterally backward because the angled ejector rod is angled. Therefore, the automotive rearview mirror product can be ejected. Thus, this utility model can realize the automatic ejection of automotive rearview mirror products, which facilitates the demolding of automotive rearview mirror products after injection molding.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] This utility model provides a composite core-pulling structure for a car rearview mirror with a straight top and angled top, as shown in the following figure. Figure 1 as well as Figure 2 As shown, the system includes a base plate 1. From bottom to top, a lower ejector plate 6, a middle ejector plate 5, and an upper ejector plate 4 are placed on the surface of the base plate 1, and the lower ejector plate 6, the middle ejector plate 5, and the upper ejector plate 4 are fixed to each other. A B plate 2 is provided above the base plate 1. Square iron 11 is bolted to both sides of the surface of the base plate 1, and the top of the square iron 11 is fixed to the bottom of the B plate 2. A rear mold core 3 is installed inside the B plate 2. A slanted straight ejector mechanism 7 is provided between the rear mold core 3 and the base plate 1, which passes through the B plate 2, the upper ejector plate 4, the middle ejector plate 5, and the lower ejector plate 6 in sequence. The slanted straight ejector mechanism 7 is used for the straight and slanted ejector combined core pulling operation of the product. A car rearview mirror product 12 is injection molded inside the rear mold core 3, and the slanted straight ejector mechanism 7 is used to eject the injection-molded car rearview mirror product 12.

[0020] During implementation, the middle ejector plate 5 is used to achieve ejection. The upper ejector plate 4, the middle ejector plate 5, and the lower ejector plate 6 form a combined secondary ejection system. The straight ejector block 71 and the inclined ejector block 72 are fixed on the lower ejector plate 6 by the inclined ejector block 72 and the inclined ejector rod 74, respectively.

[0021] Furthermore, such as Figure 2 , Figure 3 as well as Figure 4As shown, the inclined straight-push mechanism 7 includes a straight-push block 71, an inclined-push block 72, a straight-push rod 73, an inclined-push rod 74, an inclined-push universal seat 75, and a 90° universal water nozzle 76. The inclined-push universal seat 75 is fixedly connected to the interior of the middle ejector plate 5 and the lower ejector plate 6. Two movable inclined-push rods 74 are installed at an angle inside the inclined-push universal seat 75, and the bottom end of the inclined-push rod 74 passes through the inclined-push universal seat 75 and extends to the interior of the base plate 1, where the 90° universal water nozzle 76 is installed. The output end of the device passes through the upper ejector plate 4 and the B plate 2 in sequence and extends into the interior of the rear mold core 3, where a slanted ejector block 72 is installed. The slanted ejector block 72 is used for the slanted ejection of the car rearview mirror product 12. Two straight ejector rods 73 are vertically installed on the surface of the lower ejector plate 6 by bolts. The top of the straight ejector rod 73 passes through the middle ejector plate 5, the upper ejector plate 4 and the B plate 2 in sequence and extends into the interior of the rear mold core 3, where a straight ejector block 71 is installed. The straight ejector block 71 is used for the straight ejection of the car rearview mirror product 12.

[0022] During implementation, when the upper ejector plate 4, the middle ejector plate 5, and the lower ejector plate 6 move upward, the straight ejector block 71 and the inclined ejector block 72 also move upward simultaneously. The straight ejector block 71 moves upward in a straight line, while the inclined ejector block 72 moves upward and backward laterally because the inclined ejector rod 74 rotates at an angle. Therefore, it can push out the car rearview mirror product 12.

[0023] Working principle: When the product structure is limited and a through-type angled ejector cannot be designed, the middle ejector plate 5 is used to achieve ejection. The upper ejector plate 4, the middle ejector plate 5, and the lower ejector plate 6 form a combined secondary ejection system. The straight ejector block 71 and the angled ejector block 72 are fixed on the lower ejector plate 6 by the angled ejector block 72 and the angled ejector rod 74, respectively. When the upper ejector plate 4, the middle ejector plate 5, and the lower ejector plate 6 move upward, the straight ejector block 71 and the angled ejector block 72 also move upward synchronously. The straight ejector block 71 moves upward in a straight line, while the angled ejector block 72 moves backward laterally while moving upward because the angled ejector rod 74 is angled. Therefore, the car rearview mirror product 12 can be ejected.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
