Description

Technical Field

[0001] This utility model relates to the field of large-size irregular composite material molding technology, specifically a mold for preparing the net size of large-size irregular composite materials. Background Technology

[0002] Large-size irregular-shaped composite materials refer to composite material products with special shapes and sizes, typically used to meet specific application requirements. These materials require overcoming numerous technical challenges during design and manufacturing to ensure their performance and reliability. To produce large-size irregular-shaped composite materials, a mold is needed to prepare the net dimensions of these composite materials.

[0003] The mold for preparing large-size irregular composite materials, disclosed in publication number CN209682962U, features timely venting, high precision, and no need for machining. The grid-shaped overflow groove on the female mold, combined with the glue-holding groove, can recover excess resin, avoiding material shortages or resin overload in the finished product due to insufficient or uneven glue usage. Furthermore, the mold's internal cavity is connected to the external cavity, allowing for rapid venting of heated gases, preventing gas from entering the product and forming pores. Adhesive is used at the joints of the female mold to reduce sharp edges, preventing slippage and cutting of the product due to excessive clamping force or clamping direction. Demolding is performed using demolding fixtures and lifting tools, ensuring uniform stress on the product. This solves the problems of untimely venting, surface defects in the finished product, and the need for subsequent machining inherent in existing molds, thus meeting the needs of composite material molding.

[0004] However, this mold for preparing large-sized irregular composite materials has the following disadvantages:

[0005] (1) The mold for preparing large-size irregular composite material net size molding has weak maintenance and upgrade functions. When using the device, the main body of the mold cannot be disassembled for internal maintenance and upgrade, which may cause the mold production to be too simple.

[0006] (2) The mold for preparing large-sized irregular composite material net size molding has a weak cooling function. When using the device, it needs to be cooled after heating. The device cannot uniformly cool the material produced inside, which may cause defects in the material production. Utility Model Content

[0007] The purpose of this invention is to provide a mold for preparing large-sized irregular composite materials with net dimensions, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mold for preparing large-sized irregular composite material net-size molding, comprising a base plate, a mounting frame fixedly connected to the top edge of the base plate, a fixing frame snapped onto the side of the mounting frame, a mold A fixedly connected to the top end of the fixing frame, mounting components snapped onto the center of both ends of the mold A, a mold B snapped onto one end of the mounting components, threaded grooves opened at both ends of the top of the base plate, mounting bolts threadedly connected to the inner wall of the threaded grooves, a mounting block threadedly connected to one end of the mounting bolts, a fixing cover fixedly connected to one end of the mounting block, and a fixing tube fixedly connected to the outer surface of the fixing cover.

[0009] Preferably, a rectangular groove is provided at the top center of the base plate, and a bottom mold is fixedly connected to the inner wall of the rectangular groove. The bottom mold is connected to the mold body to provide a bottom model for material production.

[0010] Preferably, a connecting frame is fixedly connected to the top of mold A, and one end of the connecting frame is snapped into the top of mold B. The connecting frame is installed on the top of both mold A and mold B.

[0011] Preferably, a slot is provided at the other end of the top of the fixing frame, and an insert block is engaged with the inner wall of the slot. The top of the insert block is fixedly connected to both ends of the bottom of the mold B. The insert block on the mold B is inserted into the slot on the fixing frame, which facilitates the splicing of the mold B and the device.

[0012] Preferably, rectangular grooves are formed at both ends of the mold A, and a sealing gasket is fixedly connected to the inner wall of the rectangular groove. The sealing gasket needs to be made of ultra-high temperature material to prevent defects at the connection between mold A and mold B.

[0013] Preferably, the top of the connecting frame is provided with a through groove, and the inner wall of the through groove is fitted with a top mold. The top mold is fitted on the top of the device to provide a top model for material production.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This mold for preparing large-sized irregular composite material net-size molding, through the setup of a base plate, mounting frame, fixing frame, mold A, mounting components, and mold B, allows operators to rotate the mounting components on mold A and mold B to disengage the fixing bolt and nut at one end of the insert rod, enabling maintenance and upgrades to the interior of molds A and B. After the upgrade, the two are reconnected, the insert rod is inserted into the connection positions at both ends of mold A and mold B, and the fixing bolt and nut at one end of the insert rod are connected, thus completing the connection of the fixing frame, mold A, mounting components, and mold B. The fixing frame is then secured to the mounting frame, completing the assembly of the device. This setup facilitates maintenance and upgrades to the interior of the mold.

[0016] 2. This mold for preparing large-sized irregular composite materials is configured with a base plate, mounting bolts, mounting blocks, a fixing cover, and a fixing pipe. During use, after the mold is installed, the mounting blocks at the bottom of the fixing cover are mounted on the base plate using the mounting bolts. After the internal part of the device is heated to a high temperature, cooling water can be introduced into the fixing pipe on the fixing cover, allowing the cooling water to flow along the inside of the fixing pipe and uniformly cool the material generated inside the device. This configuration can improve the yield rate of the produced material and prevent damage to the material caused by uneven cooling. Attached Figure Description
