Description

Technical Field

[0001] This utility model relates to the technical field of ABS shoe heel molding equipment, specifically an ABS shoe heel hydraulic molding machine with a high-strength locking structure. Background Technology

[0002] ABS shoe heels are widely used in various shoe products due to their advantages such as high strength, impact resistance, and ease of processing. Their molding process mainly relies on hydraulic molding machines, which use hydraulic pressure to drive the mold to close and apply a certain pressure to solidify the ABS raw material in the mold.

[0003] Because ABS shoe heels require high-pressure molding during the molding process, existing ABS shoe heel hydraulic molding machines mainly rely on the unidirectional pressure drive of the main hydraulic cylinder when closing the mold, lacking a mold-locking function. When the main hydraulic cylinder experiences a slight pressure decay due to oil pressure fluctuations (such as a momentary drop in hydraulic pump pressure or oil circuit leakage), a gap is easily generated between the upper and lower molds, causing molten material to overflow from the gap, thereby reducing the molding quality of ABS shoe heels. Therefore, in order to solve the above-mentioned problems, an ABS shoe heel hydraulic molding machine with a high-strength mold-locking structure has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide an ABS shoe heel hydraulic molding machine with a high-strength locking structure. By setting four sets of high-strength locking mechanisms around the molding die, and combining them with the structure of the main hydraulic cylinder driving the moving table to close the upper die and the lower die of the fixed table, the defects of pressure attenuation of the main hydraulic cylinder can be compensated, the locking strength can be strengthened, and the problems mentioned in the background art can be solved.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 The ABS shoe heel hydraulic molding machine shown includes a frame 1, a main hydraulic cylinder 2, a molding die 3, and a high-strength locking mechanism 4.

[0025] A fixed platform 5 is fixedly connected to the bottom of the frame 1, and a movable platform 6 is slidably connected to the middle of the frame 1. The forming mold 3 includes an upper mold 31 and a lower mold 32. The upper mold 31 is installed on the lower surface of the movable platform 6, and the lower mold 32 is installed on the fixed platform 5.

[0026] The main hydraulic cylinder 2 is installed on the top of the frame 1, and the piston rod of the main hydraulic cylinder 2 passes through the frame 1 and is fixedly connected at the center of the upper surface of the moving table 6.

[0027] The high-strength clamping mechanism 4 is provided in four sets, and the four sets of high-strength clamping mechanisms 4 correspond to the four sides of the forming mold 3 respectively;

[0028] The power source of this molding machine is an external hydraulic control system. The hydraulic control system consists of a hydraulic pump, oil tank, reversing valve, pressure sensor, overflow valve, and pipelines, etc., which provides power and precise control for the mold closing, mold opening, and mold locking auxiliary actions of the equipment. When performing ABS shoe heel molding, the hydraulic pump starts and draws hydraulic oil from the oil tank. After being pressurized, it is delivered to the main oil cylinder 2 through the pipeline. The main oil cylinder 2 drives the moving table 6 to move up and down, realizing the closing or opening of the upper mold 31 and the lower mold 32. At the same time, four sets of high-strength mold locking mechanisms 4 are set around the molding mold 3 to help enhance the mold locking effect during mold closing. The main oil cylinder 2 provides the mold closing power, and the four sets of mold locking mechanisms assist in mold locking from all sides of the mold, which can significantly improve the mold locking strength, meet the mold locking force requirements of ABS shoe heel hydraulic molding, and ensure the stability of the molding process.

[0029] Four sets of high-strength mold-locking mechanisms 4 are arranged between the moving platform 6 and the fixed platform 5. The high-strength mold-locking mechanisms 4 are used to lock the relative positions of the upper mold 31 and the lower mold 32 after the mold is closed.

[0030] Four sets of high-strength mold-locking mechanisms 4 are installed between the moving platform 6 and the fixed platform 5. When the upper mold 31 and the lower mold 32 are closed, the mold-locking mechanism is activated and acts on the moving platform 6 and the fixed platform 5, thereby locking the relative position of the upper mold 31 and the lower mold 32 and preventing relative displacement between the two after mold closing.

[0031] By specifically locking the relative position of the mold after mold closing, mold displacement caused by molding pressure can be avoided, ensuring the molding accuracy of ABS shoe heels, and further enhancing the stability and reliability of mold locking.

[0032] The high-strength mold clamping mechanism 4 includes a mold clamping column 41 and a locking cylinder 42. The bottom of the mold clamping column 41 is fixed on the fixed platform 5. Through holes 43 are opened around the surface of the moving platform 6 at positions corresponding to the mold clamping column 41. The upper end of the mold clamping column 41 passes through the through holes 43 and extends upward. The locking cylinder 42 is fixed around the outer wall of the moving platform 6. The piston rod of the locking cylinder 42 is fixedly connected to a locking block 44. The top of the mold clamping column 41 is provided with a positioning hole 45 that cooperates with the locking block 44.

[0033] In the high-strength mold clamping mechanism 4, the mold clamping column 41 is fixed on the fixed platform 5. When the moving platform 6 descends to close the mold, the upper end of the mold clamping column 41 passes through the through hole 43 of the moving platform 6. After the mold is closed, the locking cylinders 42 around the moving platform 6 drive the piston rod to move the locking block 44, so that the locking block 44 cooperates with the positioning hole 45 at the top of the mold clamping column 41 to achieve mechanical locking between the upper mold 31 and the lower mold 32.

[0034] Mechanical mold locking is achieved through the cooperation of the mold locking column 41 and the locking block 44. The structure is simple and the mold locking force is strong. It can effectively resist the internal pressure during hydraulic molding, prevent the mold from expanding, and improve the firmness and safety of the mold locking.

[0035] The locking block 44 includes a connecting plate 441 and a positioning post 442. One side of the connecting plate 441 is fixed to the piston rod of the locking cylinder 42, and the other side of the connecting plate 441 is fixedly connected to the positioning post 442. The end of the positioning post 442 away from the connecting plate 441 is inserted into the positioning hole 45.

[0036] The locking block 44 is composed of a connecting plate 441 and a positioning pin 442. The piston rod of the locking cylinder 42 drives the positioning pin 442 to move through the connecting plate 441, so that the end of the positioning pin 442 away from the connecting plate 441 is accurately inserted into the positioning hole 45 of the mold-locking pin 41. The mold-locking is completed by the insertion and cooperation between the positioning pin 442 and the positioning hole 45.

[0037] The insertion structure of the positioning pin 442 and the positioning hole 45 can achieve precise positioning. Together with the connecting plate 441, it transmits the locking force, making the mold clamping process more stable, reducing the gap between the locking block 44 and the mold clamping pin 41, and further ensuring the mold clamping accuracy and reliability.

[0038] The high-strength clamping mechanism 4 also includes a reinforcing rib 46, which is a triangular steel plate structure and is fixed to the clamping column 41.

[0039] The high-strength clamping mechanism 4 fixes the reinforcing ribs 46 of the triangular steel plate structure on the clamping column 41, and uses the stability of the triangle to enhance the overall structural strength of the clamping column 41 and reduce the deformation of the clamping column 41 caused by the force during clamping.

[0040] The reinforcing rib 46 effectively enhances the load-bearing capacity and deformation resistance of the clamping column 41, preventing damage to the clamping column 41 during long-term high-pressure clamping, extending the service life of the equipment, and ensuring the stable transmission of clamping force.

[0041] A collision protection strip 7 is provided on the inner top of the frame 1, and the collision protection strip 7 is movably connected to the upper end of the moving platform 6;

[0042] The anti-collision strip 7 at the top of the frame 1 is movably connected to the upper end of the moving platform 6. When the moving platform 6 moves upward to near the top of the frame 1, the anti-collision strip 7 first contacts the moving platform 6 and buffers the impact force of the moving platform 6 through its own deformation, so as to avoid the moving platform 6 from having a rigid collision with the top of the frame 1.

[0043] The anti-collision strip 7 can effectively absorb the impact force when the moving platform 6 rises, protect the structure of the moving platform 6 and the top of the frame 1, reduce equipment wear and collision noise, and extend the service life of the equipment.

[0044] The upper edge of the mold-locking column 41 is rounded.

[0045] The upper edge of the mold-locking column 41 is rounded. When the moving table 6 descends to close the mold, the rounded corner structure can reduce the frictional resistance between the mold-locking column 41 and the edge of the through hole 43 of the moving table 6, so that the mold-locking column 41 can pass through the through hole 43 more smoothly.

[0046] The rounded corner design reduces the difficulty of fitting the mold clamping column 41 and the through hole 43 of the moving table 6, reduces wear and jamming between the two, improves the smoothness of the mold closing process, and ensures the stability of equipment operation.
