Description

Technical Field

[0001] The utility model patent relates to the technical field of composite material molding, and specifically, to a composite material tie rod compression molding die. Background Art

[0002] At present, most traditional tie rods are made of metal, that is, they are processed from metal. The raw materials of composite tie rods are carbon fiber, epoxy resin or other materials. The characteristics of composite materials are: high specific strength, high specific modulus, light weight; good fatigue resistance; excellent high temperature characteristics; good shock absorption; good breaking safety; good dimensional stability and good chemical stability.

[0003] When preparing composite material pull rods, they need to be compounded under high temperature and high pressure, so it is necessary to develop new molding dies that are suitable for the product. Utility Model Content

[0004] The utility model aims to provide a composite material pull rod compression molding die, aiming to solve the problem.

[0005] The utility model is implemented as follows: it comprises an upper die and a lower die, a positioning pin and a guide pin are arranged between the upper die and the lower die, an upper forming plate is fixedly installed on the surface of the upper die by bolts, a lower forming plate is fixedly installed on the surface of the lower die by bolts, a positioning hole and a guide hole are opened on the surface of the lower forming plate relative to the position of the positioning pin and the guide pin, two upper forming plates are arranged, a pair of the upper forming plates are symmetrically distributed with respect to the central axis of the upper die, two lower forming plates are also arranged, a pair of the lower forming plates are symmetrically distributed with respect to the central axis of the lower die, a fractal line is arranged in the middle position of the cavity of the upper die and the lower die, and the upper die and the lower die are respectively Place it on the workbench to lay the product, and then place two forming plates on the surface of the upper mold and the lower mold respectively. At this time, the guidance of the guide pin can improve the installation efficiency of the forming plate, and then lay the product. After the laying is completed, install the positioning pins to close the mold, pressurize, and finally put it into the furnace for curing, and then take out the mold and demold it, filling the gap in the forming of composite material tie rods. In addition, this mold is easy to assemble and disassemble, has reliable connection, high rigidity, small deformation, light weight and low cost, is relatively simple to operate and use, the overall structure of the tooling is simple, the production cycle is short, and solving technical problems is faster, simpler and more environmentally adaptable than the production cycle.

[0006] Furthermore, the surfaces of the upper mold and the lower mold are both provided with steps, and the upper molding plate and the lower molding plate are both positioned and installed through the steps. The upper molding plate and the lower molding plate can be quickly positioned through the steps to further improve the installation efficiency.

[0007] Furthermore, threaded holes are provided on both sides of the upper mold and the lower mold, and the positioning pins and guide pins are each provided with no less than two and are staggered in arrangement. A sliding shaft is slidably connected to the threaded hole through a spring, and a baffle is fixedly connected to the other end of the sliding shaft, and a baffle is fixedly connected to the surface of the baffle. After the product is formed, a bolt or a lifting ring is screwed into the threaded hole for mold separation or transportation. When the bolt is screwed into the threaded hole, the bolt will squeeze the baffle, causing the baffle to retract into the threaded hole and at the same time squeeze the spring to generate elastic force. The baffle is driven by the spring to improve the bolt fixing effect. After the bolt is removed, the threaded hole can be blocked by the baffle to prevent debris from entering the threaded hole and affecting the subsequent installation of the bolt. Through a number of staggered guide pins and positioning pins, the downward force generated when the upper and lower forming plates are installed can be evenly distributed to prevent one side from sinking and getting stuck.

[0008] Furthermore, a plurality of anti-skid pads are fixedly connected to the surface of the baffle, and the anti-skid pads are made of high temperature resistant material. The baffle is hollow in design, and a feed port is provided on the surface of the baffle, and a scraper is fixedly connected to one side of the feed port, and the scraper cooperates with the inner wall thread of the threaded hole. A slot is provided on one side of the feed port, and a sealing plate is rotatably connected in the slot. When the bolt is screwed in, the friction force generated by the anti-skid pad can make the bolt drive the baffle to rotate, and the scraper will be driven to rotate at the same time as the baffle rotates, so that the scraper scrapes off the debris in the thread groove to avoid excessive wear of the bolt by the iron filings remaining in the threaded hole over time, which affects the bolt fit and reduces the service life of the bolt. When the baffle rotates to an angle of 180°, the sealing plate will automatically rotate under the influence of gravity to open the feed port. At this time, the debris accumulated on the surface of the baffle falls into the baffle for collection.

[0009] Furthermore, there are two feed ports, a pair of which are symmetrically arranged with respect to the central axis of the baffle. The sealing plate is designed to be narrow at the top and wide at the bottom. The design of narrow at the top and wide at the bottom can increase the inertia generated by the sealing plate when it rotates downward, hit the inner wall of the baffle, and then shake off the impurities on the scraper surface. The design of two feed ports can improve the debris collection efficiency.

[0010] Compared with the prior art, the utility model fills the blank in composite material tie rod forming, and the mold is easy to assemble and disassemble, has reliable connection, high rigidity, small deformation, light weight and low cost, is relatively simple to operate and use, has a simple overall structure of the tooling, and a short production cycle. It is faster and simpler to solve technical problems than the production cycle, and has stronger environmental adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
