Description

Technical Field

[0001] The utility model belongs to the technical field of composite product mold forming, and particularly relates to an auxiliary device for demolding a rod-shaped core mold after a composite product is formed. Background Art

[0002] For a composite product with multiple long through holes, when forming with a mold, multiple rod-shaped core molds need to be configured to construct the multiple long through holes in the product. After forming, the multiple rod-shaped core molds need to be removed from the product in the mold set first, and then the product is separated from the mold set. After the composite product (such as composite products of carbon fiber, glass fiber, aramid fiber, etc.) is laminated and cured, it tightly wraps around the surface of the rod-shaped core mold, and the generated contact force is relatively large, resulting in increased difficulty in demolding the rod-shaped core mold.

[0033] Referring to Figure 1 as shown, the lower part of the liftable mobile vehicle 2 is moved through the universal wheels 22, and the lifting platform 21 is lifted through a scissor lifting mechanism.

[0034] The mold fixing plate 3 is fixed to the lifting platform 21 of the liftable mobile vehicle 2 by welding or nuts. The fixed mold fixing plate 3 is strong and reliable, and is not easy to deform or fall off; the mold group 1 is placed on the lifting platform 21 of the liftable mobile vehicle 2, and the mold fixing plate 3 is used to block and limit the mold group to prevent the mold group 1 from sliding toward the cylinder during the demolding process; the first cylinder fixed mounting bracket 5 and the second cylinder fixed mounting bracket 7 are fixed to the surface of the fixed platform 8 by welding. The fixed platform 8 is required to be a heavy-duty bench that can accommodate heavy goods weighing ≥1 ton. The installation positions of the first cylinder fixed mounting bracket 5 and the second cylinder fixed mounting bracket 7 need to be adjusted according to the length and size of the cylinder body 6, so as to facilitate the cylinder body 6 to be completely fixed to the surface of the fixed platform 8 through the first cylinder fixed mounting bracket 5 and the second cylinder fixed mounting bracket 7. The push rod 9 is fixed to the lower part of the fixed platform 8 by welding. During the demoulding process of the rod-shaped core mold, the top of the push rod 9 pushes against the lifting and lowering movable vehicle 2, so that it will not move with the pulling of the cylinder telescopic rod 61, ensuring smooth demoulding operation and improving the safety factor.

[0035] See also Figure 1 and Figure 2 The mold group 1 is a mold used for curing different composite products. At the same time, its structure plays a clamping role for the product during the demolding process. The overall appearance of the mold group varies according to the shape and size of the product, and the axis lines of the several rod-shaped core molds 11 clamped in the mold group 1 are not necessarily all located in the same horizontal plane. Therefore, a lifting and moving vehicle is required to adjust according to the situation so that the rod-shaped core mold 11 to be demolded and the cylinder telescopic rod 61 can be coaxial to ensure smooth demolding.

[0036] See also Figure 2 and Figure 3 As shown, each rod-shaped core mold 11 is provided with a screw hole 110 at the end exposed from the mold set 1, which is used for screwing the screw body 121 of the connecting ring 12 of the connecting assembly and is convenient for separation after demoulding.

[0037] refer to Figure 3 In addition to the connecting ring 12, the connecting assembly also includes a connecting frame 4, one side of the frame body passes through one end of a fixed connecting rod 63 through a fixing nut 64, and a universal joint 62 ( Figure 2 ); an embedding slot 41 is provided on the other side of the frame of the connecting frame 4; the connecting ring 12 includes an integrally formed screw body 121 and a circular ring body 122, a baffle body 123 is fixed between the screw body 121 and the circular ring body 122, the baffle body 123 and the circular ring body 122 are placed in the frame of the connecting frame 4, the screw body 121 passes through the embedding slot 41 and is exposed outside the frame, the baffle body 123 and the inner wall of the frame are blocked and limited, thereby preventing the connecting ring 12 from being detached from the embedding slot 41 as a whole.

[0038] See Figure 2 , when preparing to demold a certain rod-shaped core mold 11, by adjusting the positions of the liftable moving vehicle 2 and the mold set 1, the axis of the rod-shaped core mold 11 is made to be generally coaxial with the axis of the cylinder telescopic rod 61. Align the screw body 121 of the connecting lifting ring exposed at the left end of the connecting frame 4 with the screw connection hole 110 of the rod-shaped core mold. Manually rotate the ring body 122 to screw-fix the screw body 121 and the screw connection hole 110, so as to realize the sequential connection of the rod-shaped core mold 11, the connecting lifting ring 12, the connecting frame 4, the connecting rod 63, the universal joint 62, and the cylinder telescopic rod 61, that is, complete the connection of the rod-shaped core mold 11 and the cylinder through the connection assembly.

[0039] Refer to Figure 4 , the abutting rod 9 includes a mother rod 94 and a son rod 92. The son rod 92 is sleeved into the mother rod 94 and can relatively expand and contract. A plurality of corresponding pin holes are provided on the son rod 92 and the mother rod 94. The overall length of the abutting rod is locked by passing through and fixing the pin 93; the mother rod 94 is welded and fixed to the lower part of the fixed platform 8, and the baffle 91 is fixedly connected to the top end of the son rod 92, which is used to increase the force-bearing area when abutting against the liftable moving vehicle 2 to ensure greater safety and stability.

[0040] Working principle: After the product is cured, the cooled mold set 1 to be demolded is integrally placed on the lifting platform 21 of the liftable moving vehicle 2, and it is required to be placed at the central position without deviation or inclination, and the front edge of the mold set 1 is flush with the mold fixing plate 3, which is used to support and clamp the mold set 1; adjust the cylinder telescopic rod 61 of the cylinder to the maximum position of the cylinder stroke; adjust the left and right positions and the lifting height of the liftable moving vehicle 2 so that the axis of the rod-shaped core mold 11 clamped by the mold set 1 and the axis of the cylinder telescopic rod are basically on the same straight line; manually rotate the ring body 122 to screw-fix the screw body 121 and the screw connection hole 110, so as to realize the sequential connection of the rod-shaped core mold 11, the connecting lifting ring 12, the connecting frame 4, the connecting rod 63, the universal joint 62, and the cylinder telescopic rod 61, that is, complete the connection of the rod-shaped core mold 11 and the cylinder through the connection assembly; adjust the relative telescopic length of the son rod 92 of the abutting rod 9 so that the baffle 91 at the top end of the son rod can abut against the liftable moving vehicle, and lock the relative positions of the son rod and the mother rod with the fixing pin 93, that is, lock the overall length of the abutting rod 9; after the preparation work is completed, adjust the cylinder. As the cylinder telescopic rod 61 retracts into the cylinder body, the rod-shaped core mold 11 can be smoothly pulled out and demolded from the product in the mold set 1.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
