Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, and in particular to a vacuum hot press molding machine. Background Technology

[0002] Molding machines are simple and common processing devices in the plastics processing industry. They mainly utilize the heating and processing of molds, the injection of test material, and the pressure to fix the mold on the heating plate. The melting temperature and time of the test material are controlled to achieve melting, hardening, cooling, and then the finished product can be removed from the mold.

[0003] Existing Chinese patent CN206937788U, published on January 30, 2018, discloses a high-precision automatic rapid vacuum hot pressing molding machine, including a machine casing, a pull rod, and a booster cylinder. Dust collection hoods are installed on both sides of the upper end of the machine casing. A pull rod is installed inside the dust collection hood, and a fixed pad is fixedly connected to the top of the pull rod. A booster cylinder is installed at the upper end of the fixed pad, and a movable pad is bolted to the bottom end of the booster cylinder. An upper vacuum hood is installed at the lower end of the movable pad. This invention, through the installation of a dust collection box, can prevent dust from entering the rubber product, improving processing precision. It also allows air circulation at the upper end of the machine casing, preventing moisture buildup. The installation of a first and second insulation layer effectively prevents heat loss from the upper and lower vacuum hoods, while also preventing the surrounding side walls of the upper and lower vacuum hoods from getting too hot. The installation of heat-insulating gloves effectively prevents burns to the hands caused by excessive temperature, and also improves work efficiency.

[0004] However, when the upper vacuum cover of the above-mentioned device moves downward, it can be limited in movement because it is sleeved on the pull rod. However, when the whole device moves, the contact between the two makes the movement not very fast and convenient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vacuum hot press forming machine. The upper rolling vacuum cover is raised and lowered on the positioning support rod by an upper hydraulic cylinder, which makes the raising and lowering process more stable and convenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vacuum hot press forming machine includes a lower vacuum hood, which is fixedly mounted on the upper part of a bottom machine body. A positioning support rod is provided on the outer side of the bottom machine body, and an upper rolling vacuum hood is provided around the positioning support rod. A top panel is provided above the upper rolling vacuum hood on the positioning support rod, and an upper hydraulic cylinder is provided on the inner side of the top panel. A side vacuum cleaner is provided at the left end of the bottom machine body, and a vacuum body is provided at the right end of the bottom machine body.

[0007] The above technical solution involves using a side vacuum cleaner to remove dust from the lower vacuum hood at the top of the bottom of the machine body. Then, the upper hydraulic cylinder extends, causing the upper rolling vacuum hood to move to its upper limit on the positioning support rod. The upper rolling vacuum hood then closes with the lower vacuum hood, creating a vacuum in the closed area between the upper and lower vacuum hoods. This facilitates vacuum hot pressing of the workpiece inside the upper and lower vacuum hoods. The upper rolling vacuum hood rolls up and down on the positioning support rod via the upper hydraulic cylinder, making the lifting and lowering process more stable and convenient.

[0008] The present invention is further configured such that the positioning support rod includes a support rod, a locking nut and a metal screw, the upper end of the support rod is provided with a metal screw, the metal screw is provided with a locking nut on its periphery, the support rod is connected to the bottom body, and the metal screw is connected to the top panel through the locking nut.

[0009] The above technical solution facilitates the use of positioning support due to the positioning support rod structure.

[0010] The present invention is further configured such that the upper rolling vacuum cover includes a lower cover body, rolling balls, ball sleeves and an upper panel. Ball sleeves are provided at the four corners of the upper panel, and rolling balls are provided inside the ball sleeves. The lower cover body is provided at the lower end of the upper panel. The upper panel is connected to an upper hydraulic cylinder. The ball sleeves are in rolling contact with the positioning support rod through the rolling balls.

[0011] The above technical solution utilizes a rolling vacuum cover structure, which facilitates rolling and movement, making it more convenient to move.

[0012] The present invention is further configured such that the side vacuum cleaner includes a mounting base plate, a dust collection box, an outer dust collection groove, a dust collection head, and a connecting hose. The dust collection box is provided at the upper end of the mounting base plate, the connecting hose is provided at the upper end of the dust collection box, the dust collection head is provided at the outer end of the connecting hose, and the outer dust collection groove is provided on the inner side of the outer end of the dust collection head. The mounting base plate is connected to the bottom body.

[0013] The above technical solution facilitates side-mounted vacuum cleaner use due to the side-mounted vacuum cleaner structure.

[0014] The present invention is further configured such that the four corners of the upper rolling vacuum cover are fitted onto the positioning support rod.

[0015] Through the above technical solution, the four corners of the upper rolling vacuum cover are fitted onto the positioning support rods, thus making the upper rolling vacuum cover more stable when it rolls and moves.

[0016] The present invention is further configured such that the upper hydraulic cylinder and the upper rolling vacuum cover are connected by screws, and a sealing gasket is provided at the connection between the upper hydraulic cylinder and the upper rolling vacuum cover.

[0017] The above technical solution is effective because the upper hydraulic cylinder and the upper rolling vacuum cover are connected by screws, and a sealing gasket is provided at the connection between the upper hydraulic cylinder and the upper rolling vacuum cover. This makes it easy to install and fix, and the fixing is more tight and secure.

[0018] The present invention is further configured such that the upper rolling vacuum shroud and the lower vacuum shroud are connected to the vacuum machine body via rubber tubes.

[0019] The above technical solution facilitates vacuuming because the upper and lower vacuum hoods are connected to the vacuum machine body via rubber tubing.

[0020] The present invention is further configured such that there are four positioning support rods, and the positioning support rods are symmetrically arranged at the four corners of the upper end of the bottom body.

[0021] The above technical solution provides a stable positioning solution because there are four positioning support rods, which are symmetrically positioned at the four corners of the upper part of the bottom body.

[0022] The beneficial effects of this utility model are as follows: By incorporating an upper rolling vacuum cover structure, it facilitates rolling movement. The upper panel of the upper rolling vacuum cover is connected to the upper hydraulic cylinder, which effectively changes the position of the upper panel when the upper hydraulic cylinder extends or retracts. The ball bearing sleeve at the corner of the upper panel rolls into contact with the positioning support rod through rolling balls, making the upper panel more stable when moving up and down. The upper panel then facilitates stable vacuum hot pressing of the lower cover body below.

[0023] The side-mounted vacuum cleaner structure facilitates vacuuming. The mounting base plate of the side-mounted vacuum cleaner is welded to the bottom of the main body, allowing the dust collection box at the top of the mounting base plate to be placed stably. When the fan inside the dust collection box generates suction, the suction is transmitted to the vacuum head through the connecting hose, and then through the outer suction groove of the vacuum head, thus adsorbing external dust for cleaning. The dust is then filtered by the filter element above the fan in the dust collection box. Attached Figure Description
