Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment mold technology, specifically to a quick mold changing tooling for a mold pressing device. Background Technology

[0002] Currently, the mold installation for fuel tank blow molding equipment uses bolts to fix the mold to the equipment back plate. This method has the following drawbacks: Firstly, manually tightening the bolts results in low mold-changing efficiency, directly impacting production efficiency. Secondly, the threads on the equipment back plate often strip after long-term use, and due to the high-speed operation and frequent mold closing during production, the mold fixing bolts are prone to loosening, which can easily damage the equipment and mold over time. Utility Model Content

[0003] The purpose of this invention is to provide a quick mold changing fixture for a mold pressing device. This quick mold changing fixture not only improves mold changing efficiency but also reduces the risk of equipment and mold damage caused by loose bolts during production.

[0004] To achieve the above objectives, this utility model provides a quick mold changing fixture for a mold pressing device. The quick mold changing fixture includes a hydraulic cylinder and a T-shaped mounting block formed on the hydraulic cylinder. The hydraulic cylinder is equipped with a clamping column, and is configured to drive the clamping column to push out or retract to approach or move away from the clamping surface on the T-shaped mounting block. The hydraulic cylinder has an interface for connecting to an oil inlet pipe and a pressure regulating valve for adjusting the oil pressure. The T-shaped mounting block is configured to mate with a T-slot on the mold mounting back plate, and a planar groove is formed on the pressing surface of the clamping column.

[0005] Preferably, a proximity switch is provided on the outer wall of the connection between the T-shaped mounting block and the hydraulic cylinder, and a sensor light is connected to the proximity switch. The sensor light is set to illuminate when the mold is pressed tightly.

[0006] Preferably, the proximity switch is connected to an alarm device on the equipment and is configured to trigger an alarm when the mold is not properly clamped.

[0007] Preferably, the interface is provided with a quick-release connector.

[0008] Preferably, the T-shaped mounting block and the hydraulic cylinder are integrally formed.

[0009] Preferably, the T-shaped mounting block is detachably connected to the hydraulic cylinder.

[0010] Preferably, the T-shaped mounting block is connected to the hydraulic cylinder by bolts.

[0011] Preferably, the end of the pressure regulating valve has anti-slip embossed texture.

[0012] According to the above technical solution, this utility model improves mold changing efficiency and reduces the risk of equipment and mold damage due to loose bolts during production by adding a hydraulic cylinder clamping device and processing the mold clamping installation position into a flat groove shape to facilitate mold clamping.

[0013] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. Attached Figure Description

[0020] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0021] In this utility model, unless otherwise stated, directional words such as "inner", "outer", "far", and "near" included in the terminology only represent the orientation of the term in its normal use state, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0022] See Figure 1This utility model provides a quick mold changing fixture for a mold pressing device. The quick mold changing fixture includes a hydraulic cylinder 1 and a T-shaped mounting block 5 formed on the hydraulic cylinder 1. The hydraulic cylinder 1 is provided with a clamping column 6. The hydraulic cylinder 1 is configured to drive the clamping column 6 to push out or retract to approach or move away from the clamping surface on the T-shaped mounting block 5. The hydraulic cylinder 1 has an interface 4 for connecting to an oil inlet pipe and a pressure regulating valve 3 for adjusting the oil pressure. The T-shaped mounting block 5 is configured to cooperate with a T-slot on the mold mounting back plate for quick installation onto the equipment back plate. A planar groove is formed on the pressing surface of the clamping column 6.

[0023] Through the above technical solution, this utility model adds a hydraulic cylinder clamping device and processes the mold clamping installation position into a flat groove shape to facilitate mold clamping (the clamping column 6 will be pushed out when clamping and will be retracted when unloading the mold). This replaces the existing method of manually tightening bolts to secure the mold, which not only improves the mold changing efficiency, but also reduces the risk of equipment and mold damage caused by loose bolts during the production process.

[0024] In this embodiment, since the mold closes frequently and at high speed during production, to prevent the quick-pressing device from failing to properly clamp the mold during operation, preferably, a proximity switch 2 is provided on the outer wall of the connection between the T-shaped mounting block 5 and the hydraulic cylinder 1. The proximity switch 2 is connected to a sensor light, which is set to illuminate when the mold is clamped. Furthermore, the proximity switch 2 is connected to an alarm device on the equipment and is configured to sound an alarm when the mold is not properly clamped.

[0025] After hoisting the mold to the installation position on the back plate of the equipment, move the hydraulic cylinder 1 to the mold clamping position and operate the clamping switch. When the mold is clamped in place, the sensor light will show yellow, indicating that it has been clamped in place. If the mold is not clamped in place, the equipment will alarm and the equipment will not be able to operate fully automatically.

[0026] In this embodiment, to simplify installation and shorten the production cycle, the interface 4 is preferably equipped with a quick-connect connector. The quick-connect connector allows for fast, accurate, and efficient connection, saving time and effort.

[0027] In one embodiment, in order to improve the overall integrity of the mold changing fixture of the rapid molding device and the stability during installation and use, it is preferable that the T-shaped mounting block 5 and the hydraulic cylinder 1 are integrally formed.

[0028] In another embodiment, in order to reduce the complexity of processing each component and to facilitate disassembly and installation during replacement or maintenance, the T-shaped mounting block 5 is preferably detachably connected to the hydraulic cylinder 1.

[0029] The aforementioned detachable connection method can be any structure commonly found in the art that enables quick connection. However, from the perspective of ease of operation and cost savings, it is preferable that the T-shaped mounting block 5 is connected to the hydraulic cylinder 1 by bolts.

[0030] The pressure regulating valve 3 is used to adjust the oil pressure of the mold. To prevent slippage of the fingers when manually adjusting, the end of the pressure regulating valve 3 is preferably formed with anti-slip texture.

[0031] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0033] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
