Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile seats, and particularly relates to a central armrest foam mold with a built-in core slider. Background Technique
[0002] When processing the central armrest on an automobile seat, a steel wire frame (skeleton) is usually arranged in a foam mold, and then a foaming material is injected into the foam mold. The steel wire frame is fixed in the foamed part by integral foaming molding, and then other components are installed and the skin is covered. To ensure the effective connection between the skin and the skeleton, during integral foaming molding, an avoidance position is usually set at the position where it needs to be fixed to the skin, so that the steel wire frame is exposed.
[0003] In the existing foam mold, an avoidance block is usually arranged on one side of the mold body facing the avoidance position, and the steel wire frame that needs to be exposed is arranged in the avoidance block. After integral foaming molding, a concave groove-shaped structure will be formed at the position of the avoidance block, and the steel wire frame at this position will be in an exposed state. However, the existing foam mold is only applicable to the central armrest with a large size. For the armrest with a narrow width, because the exposed part of the steel wire frame will tilt towards the core position of the foam mold and be fixed on the avoidance block, when the central armrest is taken out upward after integral foaming molding, the deformation amount of the steel wire frame in the narrow mold cavity is small, resulting in that the product part is easily damaged during the part-taking process. The taken-out part needs secondary repair, and some parts are directly scrapped due to serious damage, increasing the product manufacturing cost and affecting the production rhythm. Summary of the Invention
[0004] In view of the above technical problems and disadvantages, the purpose of the utility model is to provide a central armrest foam mold with a built-in core slider. The foam mold improves the core position of the existing mold to make it a sliding structure. Before injecting the foaming material, the sliding structure drives the avoidance block to complete the fixation of the position to be avoided by the steel wire frame. After integral foaming molding, the sliding structure drives the avoidance block to retreat, so as to smoothly take out the foamed part and avoid damaging the product part during the part-taking process.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A central armrest foam mold with a built-in core slider, including a foam mold body. The improvement is that an installation area is processed at the core position of the foam mold body, and a first double-rod piston cylinder and a second double-rod piston cylinder are arranged in the installation area. The first double-rod piston cylinder and the second double-rod piston cylinder are arranged side by side. One of the two piston rods of the first double-rod piston cylinder and the second double-rod piston cylinder is a left piston rod, and the other is a right piston rod. The left piston rod and the right piston rod face two opposite directions respectively. Left baffles are installed on the two left piston rods, and right baffles are installed on the two right piston rods. On the side of the left baffle and the right baffle facing the wire frame and opposite to the position to be cleared, left clearance blocks and right clearance blocks are provided. On the side of the left clearance block and the right clearance block facing the wire frame, left fixing slots and right fixing slots are provided. Before integral foam molding, the wire frame at the position to be cleared is arranged in the left fixing slot and the right fixing slot; after integral foam molding, the wire frame at the position to be cleared is separated from the left fixing slot and the right fixing slot.
[0007] As a preference of the present utility model, both the left clearance block and the right clearance block are provided with two, and the two left clearance blocks and the two right clearance blocks are respectively arranged near the two ends of the left baffle and the right baffle.
[0008] As a preference of the present utility model, both the first double-rod piston cylinder and the second double-rod piston cylinder are connected to compressed air through pipelines, and electromagnetic valves are provided on the pipelines, and the cylinders are controlled by a controller to act; and the piston rods of the first double-rod piston cylinder and the second double-rod piston cylinder move in two directions, with the same speed, stroke, pulling force and pushing force.
[0009] Advantages and beneficial effects of the present utility model: The foam mold provided by the present utility model improves the core position of the existing mold to make it a sliding structure. Before injecting the foaming material, the sliding structure drives the clearance blocks to complete the fixation of the wire frame at the position to be cleared, ensuring the stability of the wire in the cavity; after integral foam molding, the sliding structure drives the clearance blocks to retreat, so as to smoothly take out the foamed part, avoiding damage to the product part during the part-taking process (wire deformation caused by no part-taking), and ensuring the qualification rate of the product.

[0019] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0020] Such as Figures 1 to 5As shown in the figure, this embodiment provides a central armrest foam mold with an internal core slider, including a foam mold body 1. The improvement is that an installation area (not shown) is processed at the core position of the foam mold body 1. A first double-rod piston cylinder 2 and a second double-rod piston cylinder 3 are arranged in the installation area. The first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 are arranged side by side. One of the two piston rods of the first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 is a left piston rod 21, 31, and the other is a right piston rod 22, 32. The left piston rod and the right piston rod face two opposite directions respectively. Left baffles 5 are installed on the two left piston rods 21, 31, and right baffles 6 are installed on the two right piston rods 22, 32. On the side of the left baffle 5 and the right baffle 6 facing the wire frame 4, left avoidance blocks 7 and right avoidance blocks 8 are arranged at positions opposite to the to-be-avoided position A. On the side of the left avoidance block 7 and the right avoidance block 8 facing the wire frame 4, left fixing slots 71 and right fixing slots (not marked) are provided. Before integral foam molding, the wire frame 4 at the to-be-avoided position A is arranged in the left fixing slot 71 and the right fixing slot; after integral foam molding, the wire frame 4 at the to-be-avoided position A breaks away from the left fixing slot and the right fixing slot.
[0021] Furthermore, in this embodiment, according to the structure of the central armrest, both the left avoidance block 7 and the right avoidance block 8 are provided with two, and the two left avoidance blocks 7 and the two right avoidance blocks 8 are respectively arranged near the two ends of the left baffle 5 and the right baffle 6.
[0022] As a preference of the present utility model, both the first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 are connected to compressed air through pipelines. Solenoid valves are provided on the pipelines. The first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 are controlled by a controller to act. Moreover, the piston rods of the first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 perform bidirectional movement, with the same speed, stroke, pulling force, and thrust force. The common action of the two double-rod piston cylinders can ensure the stability of the wire in the cavity.
[0023] After adopting this foam mold, before injecting the foaming material, the first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 drive the left avoidance block 7 and the right avoidance block 8 to extend outwards to the left and right respectively. The left avoidance block 7 and the right avoidance block 8 complete the fixation of the wire frame 4 at the to-be-avoided position A by using the fixing slots in the structure, ensuring the stability of the wire in the cavity; after integral foam molding, the first double-rod piston cylinder 2 and the second double-rod piston cylinder 3 drive the left avoidance block 7 and the right avoidance block 8 to retract. At this time, the wire frame 4 breaks away from the fixing slot, and the foamed part can be directly taken out upwards. The operation process is simple, and the wire frame 4 will not be deformed during the part-taking process, avoiding damage to the foamed part and ensuring the qualification rate of the product.
[0024] The above are the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
