Description

Technical Field

[0001] This utility model relates to the field of wing forming technology, and more specifically, to a wing forming mold device with expansion compensation function. Background Technology

[0002] Projectile wing molding is a process that uses molds to shape projectile wing materials such as thermosetting plastics, thermoplastic plastics, and rubber. Compression molding or combination molds are commonly used. The process involves steps such as material placement, mold closing, and pressure curing. The mold structure includes upper and lower molds, guide pillars, and guide sleeves. Precise cavity design and ensuring mold closing accuracy are required to produce projectile wing materials with accurate dimensions and smooth surfaces.

[0003] Existing molding dies cause variations in the contact pressure between the wing and the die surface during material expansion, affecting the wing's surface finish. Excessive expansion pressure can lead to indentations and dents on the wing surface; uneven pressure can cause surface ripples and warping, impacting the wing's aerodynamic shape and appearance, and increasing the difficulty and cost of subsequent grinding and finishing processes. Therefore, we propose a wing molding die device with expansion compensation function. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features sliding upper and lower limit plates within the upper and lower mold bases. These limit plates are fixed in position by injecting liquid through upper and lower infusion pipes. During the expansion of the thermoplastic material during heating and molding, the limit plates slide within the arc-shaped and straight plates, compensating for the pressure generated by the expansion in real time. This design effectively avoids defects such as indentations and dents on the wing surface caused by excessive expansion pressure, or surface ripples and warping due to uneven pressure.

[0021] like Figures 1 to 6 As shown, this utility model relates to a wing forming mold device with expansion compensation function, including a worktable 1, a movable component 2 and a lower mold component 4 disposed on the worktable 1, and an upper mold component 3 disposed on the movable component 2; the upper mold component 3 includes an upper mold base 301 installed at the bottom of the movable component 2, the upper mold base 301 is composed of an upper arc plate 3011 and an upper straight plate 3012, both the upper arc plate 3011 and the upper straight plate 3012 are slidably connected to an upper limit plate 302, the top of the upper arc plate 3011 is fixedly connected to an upper air storage pipe 304, the upper air storage pipe 304 is rotatably connected to a first valve 305, and the top of the upper straight plate 3012 is fixedly connected to an upper infusion pipe 303; the lower mold component 4 includes a lower mold base 401, the lower mold base 401 is fixedly connected to the top of the worktable 1.

[0022] This invention features a sliding upper limit plate 302 and a lower limit plate 402 within the upper mold base 301 and the lower mold base 401. These plates are fixed in position by liquid injection via the upper and lower infusion pipes 303 and 403. When the thermoplastic plastic expands during heating and molding, the upper limit plate 302 and the lower limit plate 402 slide within the upper arc-shaped plate 3011 and the upper straight plate 3012 to compensate for the pressure. This prevents defects such as indentations, dents, ripples, and warping from occurring on the warp wings due to excessive or uneven expansion pressure, ensuring surface smoothness and aerodynamic precision, and reducing the difficulty and cost of subsequent grinding and finishing.

[0023] In embodiments of this utility model, such as Figure 2 As shown, the movable component 2 includes a fixed frame 205, which is fixedly connected to the top of the worktable 1, and a mounting bracket 206 is fixedly connected to the top of the fixed frame 205. The fixed frame 205 facilitates the installation of the mounting bracket 206.

[0024] In embodiments of this utility model, such as Figure 3 , Figure 4As shown, a motor push rod 201 is fixedly connected to the top of the mounting bracket 206. Several limiting sleeves 203 are fixedly connected to both ends of the top of the mounting bracket 206, and the limiting sleeves 203 are slidably sleeved on the annular outer wall of the slide rod 202. The mounting bracket 206 facilitates the installation of the motor push rod 201, and the limiting sleeves 203 facilitate the vertical downward movement of the slide rod 202.

[0025] In embodiments of this utility model, such as Figure 3 , Figure 4 As shown, a fixed plate 207 is fixedly connected to the ends of the motor push rod 201 and the slide rod 202. Several limiting rods 204 are fixedly connected to the bottom of the fixed plate 207, and the ends of the limiting rods 204 are fixedly connected to the top of the upper mold base 301. By driving the motor push rod 201, the output end of the motor push rod 201 moves downward, causing the slide rod 202 to move synchronously, pushing the fixed plate 207 downward. When the fixed plate 207 moves, it causes the limiting rods 204 to move, making the upper mold base 301 closer to the lower mold base 401.

[0026] In embodiments of this utility model, such as Figure 5 As shown, the lower mold base 401 consists of a lower arc-shaped plate 4011 and a lower straight plate 4012. A lower limiting plate 402 is slidably connected inside both the lower arc-shaped plate 4011 and the lower straight plate 4012. A lower infusion pipe 403 is fixedly connected to the top of the lower straight plate 4012. When the worker places the projectile model to be shaped into the lower mold base 401, the lower limiting plate 402 changes according to the volume of the projectile model, ensuring that the lower limiting plate 402 is consistent with the surface of the projectile model. Then, a heavier liquid is delivered into the lower mold base 401 through the lower infusion pipe 403 to limit and fix the lower limiting plate 402. Afterward, the projectile model is removed, and thermoplastic material is placed on it for heating and shaping.

[0027] In embodiments of this utility model, such as Figure 5 As shown, a lower gas storage pipe 404 is fixedly connected to the top of the lower arc-shaped plate 4011, and a second valve 405 is rotatably connected inside the lower gas storage pipe 404. When there is gas inside the lower arc-shaped plate 4011, the gas is collected through the lower gas storage pipe 404, and then the second valve 405 prevents the gas from entering and exiting the lower gas storage pipe 404.

[0028] Working principle: This embodiment provides a wing forming mold device with expansion compensation function. In use, the wing model to be shaped is first placed in the lower mold base 401. The motor push rod 201 is started, and the output end of the motor push rod 201 moves downward, driving the slide rod 202 to move vertically downward along the limiting sleeve 203, thereby pushing the fixing plate 207 to move downward. The fixing plate 207 drives the upper mold base 301 to approach the lower mold base 401 through the limiting rod 204 until the upper mold base 301 and the lower mold base 401 are in contact with each other. During the contact process, the shaped wing model located between the upper mold base 301 and the lower mold base 401 will push the lower limiting plate 402 and the upper limiting plate 302, so that they move with the volume change of the shaped wing model, ensuring that the upper limiting plate 302 and the lower limiting plate 402 are consistent with the surface shape of the shaped wing model. Subsequently, heavier liquid is delivered to the lower mold base 401 through the lower infusion pipe 403. The pressure of the liquid fixes the lower limit plate 402 in the corresponding position, and then the plastic wing model is removed. Next, thermoplastic plastic is placed into the lower mold base 401, and the upper mold base 301 is closed. At this time, if the thermoplastic plastic expands during the heating and molding process, the pressure generated will cause the upper limit plate 302 and the lower limit plate 402 to slide in the corresponding arc plate and straight plate to compensate for the expansion and avoid problems such as indentation or dent on the surface of the wing due to excessive pressure, or surface ripples or warping due to uneven pressure. When gas is generated in the upper arc plate 3011 and the lower arc plate 4011 due to the expansion of thermoplastic plastic, the gas is collected through the upper gas storage pipe 304 and the lower gas storage pipe 404 respectively. By rotating the first valve 305 and the second valve 405, the entry and exit of gas in the gas storage pipe can be controlled to ensure the stability of the internal pressure of the mold. After the wing is formed, the motor push rod 201 is started in reverse to separate the upper mold base 301 from the lower mold base 401, and the formed wing can be taken out.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
