Description

Technical Field

[0001] This invention belongs to the field of molding and processing technology, and in particular relates to an automatic leveling mold press for cones and circles based on the modification of a press. Background Technology

[0002] Compression molding is a molding method for thermosetting composite materials. It involves adding a certain amount of premixed or prepreg material into a metal mold and then curing it under pressure. Compression-molded products have high dimensional accuracy, good repeatability, and a smooth surface finish, and are easily mechanized and automated. It is mainly used for the production and processing of complex parts such as structural components, connectors, and protective components. Furthermore, it is widely used in many fields including industry, agriculture, electrical appliances, machinery, weaponry, aircraft, and transportation.

[0003] The mechanical equipment used in compression molding is called a mechanical press and a hydraulic press. Most existing top-mounted hydraulic presses have a three-beam, four-column frame structure. A piston cylinder is installed on the upper crossbeam, and the distance between the movable work platform and the base is adjusted via the piston rod to achieve mold processing.

[0004] With the continuous development and updating of molding technology, molding machines are gradually moving towards a more advanced level, and the precision requirements for molding machines are also getting higher and higher. However, in the existing molding process, the fitting accuracy between the upper and lower molds cannot be effectively controlled, resulting in inconsistent forming quality of molded parts, which also restricts the development of molding machines towards higher precision.

[0005] Therefore, it is essential to invent an automatic leveling molding press for cones and circles based on the modification of a press. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a cone-circle shared automatic leveling molding press based on a modified press, comprising a base, guide rods, and a crossbeam. The key features are: multiple guide rods are used, and the guide rods are installed at the four corners above the base; the crossbeam is installed on the upper end of the guide rods; a piston cylinder is installed at the middle position above the crossbeam; a piston rod is installed on the output component at the lower end of the piston cylinder; a movable working platform is installed at the lower end of the piston rod, and the four corners of the movable working platform are fitted onto the outside of the guide rods; a mounting plate is installed at the middle position of the lower side of the movable working platform; a spherical segment and an anti-detachment mushroom head limiting rod are installed at the middle position of the lower side of the upper mounting plate, and the lower end of the anti-detachment mushroom head limiting rod extends through to the spherical segment. The lower side of the spherical block is fitted with a spherical mating block, and the lower side of the spherical mating block is sleeved on the outer side of the lower end of the anti-detachment mushroom head limiting rod. The lower end of the spherical mating block is fitted with a lower mold. During the molding process, the upper mold automatically adjusts its position through the spherical mating block to keep it parallel to the lower mold. The lower mold is parallel to the base through the conical mating block and is restricted by the lower phenolic tile and the semi-circular cover plate, allowing the lower mold to move horizontally within a very small range. When the upper mold and the lower mold come into contact, the shape of the upper and lower molds affects the upper mold and the lower mold to fit together tightly, which improves the fitting accuracy of the upper and lower molds of the molding machine, improves the problem of large equipment assembly errors, and allows the molding machine to have a greater production capacity.

[0007] A lower mounting plate is installed at the center of the upper part of the base; a conical section and a semi-circular cover plate are installed at the center of the upper part of the lower mounting plate, with the upper end of the semi-circular cover plate extending to the top of the conical section; a conical mating block is installed inside the upper part of the conical section, with the upper end of the conical mating block engaged with the outer side of the upper end of the semi-circular cover plate; a lower mold is installed on the upper side of the conical mating block; a lower phenolic resin tile is installed between the conical section and the lower mounting plate; an upper phenolic resin tile is installed between the lower mold and the conical section; pressure is applied to the movable working platform by the piston rod, and the force is transmitted through the spherical mating block, allowing the upper and lower molds to mesh better, thereby stabilizing the pressure chamber, reducing overflow, improving the fit of the upper and lower molds of the molding press, improving the problem of large overflow of molding material along the seal, and further improving the dimensional accuracy and surface finish of the formed parts.

[0008] Preferably, the crossbeam and the base are symmetrically arranged and parallel to each other; the guide rods are symmetrically arranged and have a cylindrical structure; the piston cylinder is connected to the air supply system through a pipe; the four corners of the movable work platform have through guide holes, which are aligned with the guide rods, and the size of the guide holes matches the size of the guide rods; when the piston rod moves up and down, the four corners of the movable work platform move along the guide rods, and the movable work platform, in conjunction with the guide rods, guides the piston rod, ensuring that the upper and lower molds are always aligned, thus guaranteeing the normal operation of the molding machine.

[0009] Preferably, the upper mounting plate and the lower mounting plate are arranged in parallel; a hemispherical groove is provided on the upper side of the interior of the spherical block; the lower end of the anti-detachment mushroom head limiting rod is movably connected to the spherical mating block; the upper end of the spherical mating block adopts a spherical structure, and the size of the upper end of the spherical mating block matches the size of the upper side of the interior of the spherical block; the lower mold is aligned with the lower mold, and the size of the lower mold matches the size of the lower mold.

[0010] Preferably, the upper end of the semi-circular cover plate is movably connected to the conical mating block; the upper side of the interior of the conical block adopts a conical structure; the lower end of the conical mating block adopts a conical structure, and the size of the lower end of the conical mating block matches the size of the upper side of the interior of the conical block; the upper phenolic resin tiles are symmetrically arranged, and the upper phenolic resin tiles are made of phenolic resin material; the lower phenolic resin tiles are symmetrically arranged, and the lower phenolic resin tiles are made of phenolic resin material.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this invention, during the molding process, the upper mold automatically adjusts its position through a spherical mating block to keep it parallel to the lower mold at all times; while the lower mold is parallel to the base through a conical mating block and is restricted by the lower phenolic resin tile and the semi-circular cover plate, allowing the lower mold to move horizontally within a very small range. When the upper mold and the lower mold come into contact, the shapes of the upper and lower molds affect the fit between them, improving the fitting accuracy of the upper and lower molds of the molding machine, improving the problem of large assembly errors, and allowing the molding machine to have a greater production capacity.

[0013] 2. In this invention, an upper-moving hydraulic press is used. Pressure is applied to the movable work platform through the piston rod, and the force is transmitted through the spherical mating block, so that the upper and lower molds can mesh better. This makes the pressure chamber stable, reduces the amount of overflow, improves the fit of the upper and lower molds of the molding press, and improves the problem of large overflow of molding material along the seal. It can further improve the dimensional accuracy and surface finish of the formed parts.

[0014] 3. In this invention, by setting up a movable work platform and guide rods, when the piston rod moves up and down, the four corners of the movable work platform move along the guide rods. The movable work platform, in conjunction with the guide rods, guides the piston rod, ensuring that the upper mold and the lower mold are always aligned, thus guaranteeing the normal operation of the molding machine.

[0029] Working principle

[0030] In this invention, during molding, the upper mold 11 automatically adjusts its position via the spherical mating block 10 to ensure it remains parallel to the lower mold 16. The lower mold 16, parallel to the base 1 via the conical mating block 15, is also restricted by the lower phenolic resin tile 18 and the semi-circular cover plate 13, allowing it to move horizontally within a very small range. When the upper mold 11 contacts the lower mold 16, the shapes of the upper and lower molds ensure a tight fit, improving the fitting accuracy of the upper and lower molds and mitigating the problem of large assembly errors. This allows for greater production capacity of the molding machine. The use of an upward-moving hydraulic press, via a piston rod... Pressure is applied to the movable work platform 5, and the force is transmitted through the spherical mating block 10, so that the upper and lower molds can mesh better, thereby stabilizing the pressure chamber, reducing overflow, improving the fit of the upper and lower molds of the molding machine, and improving the problem of large overflow of molding material along the seal. This can further improve the dimensional accuracy and surface finish of the formed parts. With the setting of the movable work platform 5 and the guide rod 2, when the piston rod 6 moves up and down, the four corners of the movable work platform 5 move along the guide rod 2. The movable work platform 5, together with the guide rod 2, guides the piston rod 6, so that the upper mold 11 and the lower mold 16 are always aligned, ensuring the normal operation of the molding machine.
