Description

Technical Field

[0001] The utility model relates to the technical field of liquid silicone processing equipment, in particular to a liquid silicone extrusion molding device. Background Art

[0002] Liquid silicone, due to its excellent physical and chemical properties, has been widely used in electronics, medical, automotive, and other fields. Extrusion molding is a common and important method in the processing of liquid silicone. An extruder squeezes the liquid silicone into a mold for molding and cooling. However, existing liquid silicone extrusion molding equipment has some shortcomings during use, mainly manifested in low mold replacement efficiency, low extrusion precision, and unstable cooling effect.

[0003] Traditional liquid silicone extrusion molding equipment typically uses a fixed mold. When changing molds of different sizes or shapes, the machine must be stopped for disassembly and assembly, which is not only time-consuming and labor-intensive, but also affects production efficiency. Secondly, the mold is often fixed with bolts or clamps, which is complicated to operate and can easily lead to inaccurate positioning, affecting product consistency. In addition, the cooling molding process is also inefficient. Especially when continuous production is required, the long cooling time will significantly affect production speed. Utility Model Content

[0004] The purpose of the present invention is to provide a liquid silicone extrusion molding device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a liquid silicone extrusion molding device, comprising a base, an extruder body and a machine table, wherein the extruder body is provided at one end of the top surface of the base, a cylinder is provided inside the extruder body, and the cylinder is fixed to the top surface of the base through a support, a slide rail is provided at the other end of the top surface of the base, and the machine table is slidably mounted on the surface of the slide rail, a bottom plate is provided inside the machine table, a turntable is provided in the middle of the surface of the bottom plate, the surface of the turntable is connected to the top plate, and a notch is provided on the side of the surface of the top plate.

[0006] When using a liquid silicone extrusion molding device in the present technical solution, the staff must first connect the external power supply of the utility model and control the operation of the utility model through the control panel. The staff pours the liquid silicone into the feed barrel in the extruder body. After pouring into the inside, it will be transmitted to the inside of the cylinder. After being transmitted to the cylinder, the staff starts the motor, and the motor will rotate the spiral blade connected to the output end. The spiral blade will rotate in the cylinder and extrude the liquid silicone inside it. During the transportation, the heating sleeve will heat the cylinder so that the liquid silicone can flow at a suitable temperature. When the liquid silicone is squeezed to the extruder by the spiral blade, the liquid silicone will be squeezed out. After the extruder is cooled and formed in the mold, the staff can control the slide rail to move the machine as a whole, so that the interface on one side of the mold will be disconnected from the extruder head. At this time, the staff controls the turntable to rotate the top plate. After the top plate rotates, the four molds installed on its surface will rotate and change positions. The mold being cooled and formed is removed from the extruder head, and the empty mold will rotate and move to the extruder head. After moving to this position, the staff controls the slide rail to move the machine again, so that the extruder head will be inserted into the interface, completing the connection between the mold and the extruder body, and the extrusion molding operation can continue.

[0007] Preferably, an electric push rod is fixed in the middle of both sides of the interior of the recess, and one end of the electric push rod is connected to a clamping plate, and a mold is provided on the surface of the clamping plate, and the mold is placed in the middle of the interior of the recess. Through the cooperation of the electric push rod and the clamping plate, molds of different sizes can be clamped and fixed after being placed in the recess, achieving the effect of adapting to the installation of molds of different sizes.

[0008] Preferably, an interface is provided on one side of the exterior of the mold, which allows the extrusion head to be inserted into the mold, facilitating the connection between the extruder body and the mold, and completing the extrusion and transmission of the liquid silicone.

[0009] Preferably, a telescopic rod is fixed at both ends of the inner side of the notch, and one end of the telescopic rod is connected to the clamping plate. The telescopic rod is composed of an inner rod inserted into a sleeve rod. By providing the telescopic rod, the electric push rod stabilizes both ends of the clamping plate when it is telescoped and moved, thereby achieving the effect of stabilizing the movement of the clamping plate.

[0010] Preferably, a roller is rotatably mounted on the side of the bottom plate, and a top plate is provided on the surface of the roller. The installation of the roller allows the turntable to stabilize the side of the bottom surface when the top plate is rotated, providing a stable support effect.

[0011] Preferably, a motor is provided at one end of the outer portion of the cylinder, the output end of the motor being connected to a spiral blade disposed within the inner portion of the cylinder, and an extrusion head is connected to the other end of the outer portion of the cylinder. The cooperation between the motor and the spiral blade allows the liquid silicone to be pushed forward and plasticized, achieving a transporting and moving effect, while the configuration of the extrusion head allows the liquid silicone to be squeezed into the interior of the mold after being pushed inside by the spiral blade.

[0012] Preferably, a feed barrel is connected to one end of the outer surface of the cylinder, and a heating jacket is provided on the other end of the outer surface of the cylinder. The feed barrel facilitates the entry of the liquid silicone to be processed into the interior of the cylinder, providing a feeding position, while the installation of the heating jacket allows the cylinder to be heated to keep the liquid silicone flowing at a suitable temperature.

[0013] Preferably, the bottom surface of the base is provided with a bottom pad, and four bottom pads are provided, and the four bottom pads are distributed in a rectangular shape. The installation of the four bottom pads enables the utility model to be stably placed off the ground for use.

A movable clamping plate is provided in the notch to clamp and fix molds of different sizes. After fixing the mold, the top plate is rotated to align and connect the mold with the extrusion head of the extruder. After connection, the extruder squeezes liquid silicone into the mold for cooling and molding. When liquid silicone is squeezed into a mold, the top plate can be immediately rotated to replace the next mold for extrusion and cooling molding, thereby realizing efficient continuous production.
