Description

Technical Field

[0001] This invention relates to the field of foaming mold frame technology, and more particularly to a chain-driven electric foaming mold frame. Background Technology

[0002] Foaming molds are mainly used for the foaming process of products. They are generally installed on a mold frame, and the opening and closing of the upper and lower molds are achieved by lifting the upper mold frame with a hydraulic cylinder. However, this lifting foaming mold structure is very inconvenient when removing parts and spraying release agent, mainly because the lower surface of the upper mold faces directly downwards. This structure greatly reduces the production efficiency of foamed products. Therefore, a foaming mold frame structure that facilitates demolding is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a chain-driven electric foaming mold frame, which can solve the problems of the traditional foaming mold frame structure having an upper mold frame facing the ground for demolding operation and the inconvenience of spraying release agent.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a chain-driven electric foaming mold frame, the innovation of which is: including a frame, an upper mold frame, a lower mold frame, a drive motor assembly and a chain and sprocket assembly;

[0005] The frame has a portal frame structure and includes a base, side frames, and a top beam. The base is horizontally placed on the ground, and the side frames are a pair and vertically arranged on both sides of the base. The crossbeam is arranged horizontally on the top of the side frames. The side frames are provided with guide grooves vertically.

[0006] The upper mold frame is horizontally positioned below the top beam. The upper mold frame has a cuboid frame structure. A pair of guide blocks are connected to the end corners of the upper mold frame along its length via a pivot, and the guide blocks cooperate with guide grooves. The upper mold frame can rotate around the guide blocks. Lifting lugs are provided on the upper surface of the upper mold frame.

[0007] The lower mold frame is horizontally positioned above the base and below the upper mold frame; the lower mold frame has a cuboid frame structure, and a pair of end corners along the length of the lower mold frame are connected to the side frame via pivots, allowing the lower mold frame to rotate around the side frame;

[0008] The drive motor assembly includes a first motor, a second motor, and a third motor; the first motor and the second motor are both mounted on the top beam; the output end of the first motor is connected to a first gearbox, and the first gearbox has two output ends set at 180°, with a synchronous drive shaft passing through the two output ends of the first gearbox, and the synchronous drive shaft is rotated by the first motor driving the first gearbox; the output of the second motor is connected to a second gearbox, and the second motor is located on one side of the first motor; the second gearbox has one output end; the third motor is mounted on the side frame, and the output end of the third motor is connected to a third gearbox;

[0009] The chain and sprocket assembly includes a first chain and sprocket unit, a second chain and sprocket unit, a third chain and sprocket unit, and a fourth chain and sprocket unit. Each chain and sprocket unit has a pair of sprockets and a pair of chains, with the chains wound around the sprockets. The first chain and sprocket units are respectively located at both ends of the synchronous drive shaft. One end of the chain in the first chain and sprocket unit and one end of the chain in the second chain and sprocket unit are respectively connected to lifting lugs located along the length of the upper mold frame. The synchronous drive shaft is rotated by a first motor to realize the chain... The chains on the first chain sprocket unit and the second chain sprocket unit drive the upper mold frame to move up and down synchronously. The third chain sprocket unit is located at the output end of the second gearbox, and one end of the chain of the third chain sprocket unit is connected to the side of the upper mold frame in the width direction. The second motor drives the upper mold frame to move up, down, and rotate. The fourth chain sprocket unit is located at the output end of the third gearbox, and one end of the chain of the fourth chain sprocket unit is connected to the side of the lower mold frame. The third motor drives the fourth chain sprocket unit to rotate the lower mold frame around the side frame.

[0010] Furthermore, an electrical control box is installed on the top of the top beam.

[0011] Furthermore, a protective net is installed on the side frame, and a central control touch screen is installed on the protective net.

[0012] The advantages of this invention are:

[0013] 1) In this invention, a motor-driven chain serves as the transmission structure, replacing the conventional hydraulic cylinder-type lifting and mold-closing structure. This chain-driven foaming mold frame can be directly lifted and lowered by the motor. When the upper mold frame and the lower mold frame are separated to a certain distance, one of the motors can be controlled to continue lifting, thereby achieving an inclined state for either the upper or lower mold frame. This inclined state of the upper and lower mold frames makes it easier to remove the foamed parts and facilitates the spraying of release agent without requiring the operator to lie on their back. This chain-driven electric foaming mold frame greatly improves the production efficiency of foamed products. Attached Figure Description
