Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin molding equipment technology, specifically an epoxy resin pressure gel molding machine. Background Technology
[0002] The automatic pressure gelation process for epoxy resin is a relatively new technology that produces epoxy products with good mechanical and electrical properties, and is widely used in the electrical appliance industry.
[0003] Its process is similar to that of thermoplastic injection molding. First, various materials are mixed evenly in a mixing tank. After vacuum degassing, the liquid material is injected into the mold under a certain pressure. While the air is expelled from the mold cavity, the liquid material fills the entire cavity. At a high mold temperature, the liquid material solidifies rapidly after contacting the mold wall.
[0004] The epoxy resin pressure gel molding machine is the main production equipment for automatic epoxy resin pressure gel. It is mainly used to support the module and open and close the mold. The mold is fixed on the mold mounting plate inside the equipment. After the mold is pushed to close by a hydraulic cylinder, the liquid material is injected. In actual use, there are some functional deficiencies and room for improvement. For example, during long-term use, the piston position of the hydraulic cylinder is prone to deviation, which will reduce its accuracy. This is reflected in the equipment as a poor mold closing effect and problems such as liquid and air leakage. It does not have the function of electrical clamping to prevent deviation.
[0005] Now, a novel epoxy resin pressure gel molding machine is proposed to solve the above problems. Utility Model Content

A third electric cylinder is fixedly connected to the middle position of the top of the internal nut sliding plate. A top pressing plate is fixedly connected to the output end of the third electric cylinder. Limiting guide rods are vertically welded to the front and rear ends of the top of the top of the top pressing plate. Limiting tube seats are welded to the front and rear ends of the top of the internal nut sliding plate.
[0009] As a further technical solution of this utility model, the first mold fixing plate and the second mold fixing plate have the same shape and size, and the horizontal center lines of the first mold fixing plate and the second mold fixing plate coincide.

[0012] As a further technical solution of this utility model, two sets of metal guide plates are fixedly connected inside the left side of the second mold fixing plate, two sets of ultrasonic transducers are fixedly connected to the right side of the second mold fixing plate, an ultrasonic generator is horizontally placed at the top of the controller, and transducer wiring is movably connected between the ultrasonic transducer and the ultrasonic generator.
[0013] As a further technical solution of this utility model, the right side of the second mold fixing plate and the metal guide plate are flush, the left side of the ultrasonic transducer and the right side of the metal guide plate are fixedly connected, and the ultrasonic transducer, transducer wiring and ultrasonic generator are electrically connected.
[0014] As a further technical solution of this utility model, a cylindrical fixing block is fixedly connected to the bottom of the steel support leg, a fourth electric cylinder is fixedly connected to the top of the cylindrical fixing block, and a columnar support block is fixedly connected to the output end of the fourth electric cylinder.

[0017] (1) By setting up a first electric cylinder, a second electric cylinder, a servo motor and a third electric cylinder, when in use, the left and right sets of molds are fixed on the first mold fixing plate and the second mold fixing plate respectively.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the ultrasonic generator 23 continuously supplies power to the ultrasonic transducer 21 through the transducer wiring 22. The high-frequency vibration emitted by the ultrasonic transducer 21 is transmitted to the liquid material in the mold through the metal guide plate 20 and spreads rapidly with the liquid material as the medium.

[0034] Working Principle: In use, the two sets of molds are first fixed on the first mold fixing plate 4 and the second mold fixing plate 19, respectively. The second electric cylinder 8 pushes the left mounting plate 5 to the right, causing the first mold fixing plate 4 and the second mold fixing plate 19 to come close together, and the molds close. The first electric cylinder 2 pushes the bottom support plate 3 upward to press against the bottom of the mold, and the third electric cylinder 15 pushes the top pressing plate 18 downward to press against the top of the mold. The first electric cylinder 2, the second electric cylinder 8, and the third electric cylinder 15 replace the original hydraulic cylinder, making it easier to control the precision. Moreover, the equipment does not require additional hydraulic devices, resulting in lower costs. After the two sets of molds close, liquid is injected. At the same time as the liquid is injected, the ultrasonic generator 23 is activated. The ultrasonic generator 23 continuously supplies power to the ultrasonic transducer 21 through the transducer wiring 22. The high-frequency vibration emitted by the ultrasonic transducer 21 is transmitted to the liquid inside the mold through the metal guide plate 20 and spreads rapidly with the liquid as the medium. The vibration accelerates the diffusion of the liquid and eliminates internal air bubbles. When the equipment shakes during operation, locate the suspended steel support leg 25 and activate the corresponding fourth electric cylinder 27. The fourth electric cylinder 27 pushes the columnar support block 28 to extend downward along the cylindrical fixing block 26 and press against the ground, forming an upward support force to ensure the stable operation of the equipment.
