[0002] The molding mechanism of the enamel molding machine is the core equipment for heating and solidifying the material into a specific shape. Its working efficiency and operation convenience directly affect the production rhythm and product quality. In the existing technology, enamel molding usually requires processes such as raw material injection, mold closing and heating, cooling and solidification, and mold opening and demolding.

[0003] When it is necessary to inject the ethylene-vinyl material into the molding groove of the mold, the operator needs to manually open the mold cover. After the raw material is injected, the mold cover is manually reset and closed. After the material is heated and cured, the mold cover needs to be manually opened again to take out the molded product.

[0004] Manual control of the opening and closing of the mold cover has poor consistency, affecting production efficiency. At the same time, it is labor-intensive and prone to operational errors. In addition, during manual operation, the operator needs to come into close contact with the heated mold, posing a safety hazard of being burned by high temperature. Utility Model Content

[0005] The purpose of the utility model is to solve the following shortcomings in the prior art: the poor consistency of manually controlling the opening and closing of the mold cover affects production efficiency; the labor intensity is high and it is easy to cause operating errors; and during manual operation, the operator needs to come into close contact with the mold in a heated state, which poses a safety hazard of being burned by high temperature. An environmentally friendly molding mechanism for an enameling machine is proposed.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0024] Reference Figure 1 , an environmentally friendly enameling machine forming mechanism, including a table 1, a mold 2 is fixedly installed on the upper surface of the table 1, and a molding groove 3 is opened on the top of the mold 2. The inner side wall and bottom of the molding groove 3 are embedded with a graphene electric heating film for heating the material (the graphene electric heating film is disclosed in the patent publication number CN217338773U, and the patent name is a constant temperature egg retrieval device. It belongs to the prior art and its working principle is not described in detail here). A mold cover 4 is symmetrically and slidably installed on the top of the mold 2. An L-shaped plate is fixedly installed on the upper surface of the table 1, and a telescopic cylinder 5 is fixedly installed on the lower surface of the L-shaped plate. An L-shaped mounting plate 6 is fixedly installed on the driving shaft of the telescopic cylinder 5. A mounting ring 7 is fixedly installed on one end of the mounting plate 6. A discharge head 8 is fixedly installed on the inner wall of the mounting ring 7. The discharge head 8 is connected to an extrusion device (not shown) for extruding the material through a hose. A through hole 9 is opened on the upper surface of the mold cover 4. The two through holes 9 are combined into a through hole for the end of the discharge head 8 to pass through.

[0025] Reference Figure 3 and Figure 5The lower surface of the mold cover 4 is fixedly installed with an integrally formed oblique rod 10 and a vertical rod 11. The surfaces of the oblique rod 10 and the vertical rod 11 are provided with sliding openings, which are composed of a connected oblique opening 12 and a vertical opening 13. A U-shaped rod 15 is fixedly installed on the lower surface of the mounting plate 6 through a connecting rod 14. The two ends of the U-shaped rod 15 are respectively slidably configured in the two sliding openings.

[0026] In the initial state, the telescopic cylinder 5 is in a fully retracted state, the mounting plate 6 is at the highest point, and the discharge head 8 is synchronously at the highest position. The two ends of the U-shaped rod 15 connected by the connecting rod 14 on the lower surface of the mounting plate 6 are at the uppermost end of the oblique opening 12 of the sliding opening on the surface of the oblique rod 10 and the vertical rod 11. Under the pulling action of the U-shaped rod 15, the distance between the two mold covers 4 is the largest, and the notch of the forming groove 3 is completely in an open state, which is convenient for subsequent operations.

[0027] When it is necessary to inject material into the forming groove 3, the telescopic cylinder 5 is started to stretch its drive shaft, driving the mounting plate 6 to move vertically downward. During the descending process, the mounting plate 6 drives the mounting ring 7 and the discharge head 8 to move downward synchronously on the one hand, and drives the U-shaped rod 15 to move vertically downward through the connecting rod 14 on the other hand. At this time, both ends of the U-shaped rod 15 slide downward along the oblique openings 12 on the oblique rod 10 and the vertical rod 11. Since the oblique opening 12 is inclined, it generates a horizontal component of force on the U-shaped rod 15, pushing the two symmetrically arranged mold covers 4 to approach each other along the sliding track at the top of the mold 2.

[0028] As the driving shaft of the telescopic cylinder 5 continues to contract, the two ends of the U-shaped rod 15 slide from the oblique opening 12 into the vertical opening 13. At this time, the mold cover 4 is completely closed, and the two through openings 9 are combined into a complete through opening. Then, as the discharge head 8 continues to move downward, the two ends of the U-shaped rod 15 will move vertically in the two vertical openings 13 respectively, and the two mold covers 4 will not move again at this time until the end of the discharge head 8 passes through the through opening and extends into the appropriate position in the molding groove 3. At this time, the stretching action of the telescopic cylinder 5 is stopped, and the extrusion equipment connected to the discharge head 8 is started to inject the material into the molding groove 3 through the discharge head 8.

[0029] After the injection is completed, the extrusion equipment is turned off, and the graphene electric heating film embedded in the inner wall and bottom of the molding groove 3 starts to work to heat the injected material. After the material heating is completed, the telescopic cylinder 5 is started to shrink its drive shaft, driving the mounting plate 6 to move vertically upward. When the mounting plate 6 rises, the discharging head 8 is synchronously driven to move upward, and at the same time, the U-shaped rod 15 is driven to move vertically upward through the connecting rod 14. The two ends of the U-shaped rod 15 slide upward along the vertical opening 13. After sliding to the connection between the vertical opening 13 and the oblique opening 12, it continues to slide upward along the oblique opening 12. In the process of the U-shaped rod 15 sliding upward along the oblique opening 12, the oblique opening 12 produces a reverse horizontal component of force on the U-shaped rod 15, pulling the two mold covers 4 away from each other along the sliding track, gradually opening the notch of the forming groove 3. When the driving shaft of the telescopic cylinder 5 is fully extended, the mounting plate 6 and the discharging head 8 return to the initial highest position, and the two ends of the U-shaped rod 15 also return to the uppermost end of the oblique opening 12. The distance between the two mold covers 4 reaches the maximum again, and the notch of the forming groove 3 is fully opened. At this time, the heated and formed product in the forming groove 3 can be taken out.

[0030] During the entire process, the opening and closing of the mold cover 4 and the lifting and lowering of the discharge head 8 are achieved through the linkage of the telescopic cylinder 5, the U-shaped rod 15 and the sliding joints on the oblique rod 10 and the vertical rod 11. No manual intervention is required, which greatly shortens the operation time and improves the batch production efficiency. At the same time, it avoids the safety hazards caused by contact with the high-temperature mold 2 during manual operation.

[0031] Reference Figure 4 A spiral channel 16 is provided in the mold 2, and a cavity is provided in the platform 1. The cavity is divided into a water storage area 18 and an installation area 19 by a partition 17. The installation area 19 is provided with a water supply component for supplying water in the water storage area 18 to the top of the channel 16. A return pipe 20 is fixedly connected to the bottom of the channel 16, and the bottom end of the return pipe 20 penetrates into the water storage area 18.

[0032] Reference Figure 2 The water supply assembly includes a mounting column 21 and a plug rod 22. The top wall of the mounting area 19 is provided with a mounting opening. The mounting column 21 is vertically fixedly installed in the mounting opening, and a slot is vertically provided at the bottom of the mounting column 21. The plug rod 22 is sealed and slidably inserted in the slot. The plug rod 22 is controlled to move vertically back and forth through a connecting component. The connecting component includes a movable plate 25 fixedly installed at the bottom of the plug rod 22 and a connecting rod 26 fixedly installed on the upper surface of the movable plate 25. The top wall of the mounting area 19 is provided with a rectangular opening. The top of the connecting rod 26 passes through the rectangular opening and is fixedly connected to the lower surface of the mounting plate 6. The side wall of the mounting column 21 is fixedly mounted with an inlet pipe 23 and an outlet pipe 24. One end of the outlet pipe 24 passes through the top of the channel 16, and one end of the inlet pipe 23 passes through the water storage area 18. Both the inlet pipe 23 and the outlet pipe 24 are provided with a one-way valve. The conduction direction of the one-way valve in the inlet pipe 23 is from the water storage area 18 to the slot, and the conduction direction of the one-way valve in the outlet pipe 24 is from the slot to the channel 16.

[0033] When the telescopic cylinder 5 is stretched, the connecting rod 26 will move downward with the movable plate 25 and the insertion rod 22, the volume in the slot will gradually increase, the pressure will decrease, and the water in the water storage area 18 will be sucked into the slot from the water inlet pipe 23.

[0034] When the material is heated, the telescopic cylinder 5 is started to shrink its drive shaft, driving the mounting plate 6 to move upward, and the discharge head 8 moves upward synchronously. When the mounting plate 6 moves upward, the connecting rod 26 fixedly connected to its lower surface is pulled upward, and the connecting rod 26 drives the insertion rod 22 to slide upward in the slot of the mounting column 21 through the moving plate 25. As the insertion rod 22 moves upward, the space in the slot gradually shrinks and the internal pressure increases. Since the conduction direction of the one-way valve in the water outlet pipe 24 is from the slot to the channel 16, the water in the slot is pressed into the top of the channel 16 through the water outlet pipe 24. The water entering the channel 16 flows along the spiral channel 16, fully exchanges heat with the mold 2 and the molding tank 3, and absorbs the heat of the material in the molding tank 3.

[0035] As the insertion rod 22 continues to move upward, the water in the slot will be continuously pressed into the channel 16 through the outlet pipe 24. After the water flowing along the spiral channel 16 absorbs heat, it will flow back to the water storage area 18 from the bottom of the channel 16 through the return pipe 20, forming a water circulation. As a large amount of cold water continues to enter the channel 16, the temperature of the mold 2 drops rapidly, thereby accelerating the cooling speed of the material in the molding tank 3 and shortening the molding cycle.

[0036] The entire process does not require additional power to drive the water supply, and the upward movement of the mounting plate 6 is used to realize automatic water supply circulation, which is environmentally friendly and energy-saving, and can efficiently complete the cooling operation.

[0037] The inner wall of the channel 16 is coated with a smooth coating, which is polytetrafluoroethylene. Polytetrafluoroethylene can reduce the friction between the water and the contact surface of the channel 16, so that the water can flow back to the water storage area 18 along the channel 16 smoothly and reduce residue.

[0038] When the mounting plate 6 is lowered, the U-shaped rod 15 slides along the sliding surface, pushing the symmetrically arranged mold covers 4 to approach each other and close. At this time, the discharge head 8 injects material into the molding groove 3 through the through-opening formed by the through-opening 9. After the injection is completed and the material in the molding groove 3 is heated, the telescopic cylinder 5 drives the mounting plate 6 to rise, and the U-shaped rod 15 slides along the sliding surface. The two mold covers 4 will move away from each other and open. This structure does not require manual intervention, shortens the operation time, improves the efficiency of mass production, and avoids the safety hazards of manual operation.

[0039] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
