[0002] At present, as the key connecting element in hydraulic or lubricating system, the structure of filter seat gradually develops towards multi-interface, high sealing and personalization. The traditional injection mold generally adopts straight-through structure design, mainly applicable to the filter seat product with oil inlet and oil outlet respectively arranged at both ends of the filter seat, and less number of interfaces. This kind of mold usually adopts simple core-pulling mechanism to realize demolding, which meets the molding demand of conventional structure, but for new filter seat products with complex undercut structure or multi-hole interface, it is difficult to realize high-precision injection and smooth demolding, and there are great design and application limitations.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] The specific implementation of the utility model will be described in detail below in combination with specific examples.

[0024] As Figures 1-6 shown, the utility model example provides a high-precision injection mold for multi-inlet and outlet oil filter seat, including mold base plate 1, the side of mold base plate 1 is provided with oil cylinder seat 4, and the surface of oil cylinder seat 4 is installed with telescopic oil cylinder 5, the position of mold base plate 1 surface close to oil cylinder seat 4 is provided with limiting pressing strip 3, and the surface of mold base plate 1 is slidably connected with sliding block seat 7, the surface of sliding block seat 7 is movably connected with small row position sliding block seat 6, and the telescopic end of telescopic oil cylinder 5 is connected with small row position sliding block seat 6. The surface of one end of sliding block seat 7 is slidably connected on mold base plate 1, and the side surface of sliding block seat 7 is slidably connected with the surface of limiting pressing strip 3.

[0025] The surface of small row position sliding block seat 6 is fixedly connected with oil outlet hole insert pin 11 and oil inlet hole insert pin 12, and the surface of sliding block seat 7 is provided with limiting column 15.

[0026] The surface of sliding block seat 7 is fixedly connected with row position driving block 14, and the surface of row position driving block 14 is slidably connected with oil hole part reverse locking row position block 13. The surface of row position driving block 14 is provided with T-shaped sliding groove, and the surface of oil hole part reverse locking row position block 13 is provided with T-shaped sliding block matched with the T-shaped sliding groove. The surface of oil hole part reverse locking row position block 13 is provided with arc-shaped recess matched with the shape of oil outlet hole insert pin 11 and oil inlet hole insert pin 12.

[0027] In an embodiment of the utility model, the surface of the mold base plate 1 is provided with a mounting bottom plate 9, the surface of the mounting bottom plate 9 is mounted with a filter seat inner insert 10 for forming the internal cavity structure of the multi-inlet-outlet oil port filter seat 2, and the mounting bottom plate 9 and the mold base plate 1 are in fixed connection, which ensures the stable structure positioning of the inner insert 10. To realize the accurate molding of the filter seat outer contour, the side surface of the small row position sliding block seat 6 is further provided with a filter seat outer insert 8, which cooperates with the filter seat inner insert 10 to form a complete molding structure of the multi-inlet-outlet oil port filter seat 2.

[0028] The structural feature of the multi-inlet-outlet oil port filter seat 2 is that the two ends of the body 21 are symmetrically provided with oil outlets 23 and oil inlets 22, and the middle surface of the body 21 is provided with a passage hole 24 for connecting with other pipeline structures. The oil outlet insert pin 11 and the oil inlet insert pin 12 are respectively embedded in the surface of the small row position sliding block seat 6 and correspond to the structures of the oil outlet 23 and the oil inlet 22, which ensures the molding accuracy and structural consistency. When the filter seat 2 is injection molded, the system will start the demolding process, and the embodiment is optimized for the process of accurately demolding the oil outlet insert pin 11 and the oil inlet insert pin 12 from the corresponding structure.

[0029] In the specific demolding process, first, the telescopic oil cylinder 5 is started, the telescopic end of the telescopic oil cylinder 5 drives the fixedly connected small row position sliding block seat 6 to slide along the surface of the sliding block seat 7, and the oil outlet insert pin 11 and the oil inlet insert pin 12 on the small row position sliding block seat 6 perform preliminary core pulling operations. The movement of the small row position sliding block seat 6 simultaneously drags the row position driving block 14 fixedly connected thereon to move along the sliding block seat 7, and the oil hole mouth part reverse row block 13 slidingly connected to the row position driving block 14 remains in place and slides relative to the row position driving block 14 during the movement of the row position driving block 14, thereby generating relative movement.

[0030] The cleverness of the above-mentioned structure cooperation is that the surface of the oil hole mouth part reverse row block 13 can just abut against the mouth part outer wall of the filter seat 2, forming an auxiliary support and guide structure, thereby providing a reverse limiting and reverse demolding effect for the filter seat structure during the core pulling process of the oil outlet insert pin 11 and the oil inlet insert pin 12. This structure not only avoids the structural damage or strain phenomenon of the reverse structure during the demolding process, but also greatly improves the molding accuracy and sealing performance.

[0031] When the small row position slider block seat 6 moves to the position in contact with the limiting column 15, the first stage demolding is completed, and the preliminary core-pulling position is formed. Thereafter, the telescopic oil cylinder 5 continues to push the small row position slider block seat 6, but since it has formed rigid contact with the limiting column 15, the pushing force will be transmitted to the slider block seat 7, driving the slider block seat 7 to continue to slide outward on the surface of the mold base plate 1. The slider block seat 7 can only move along the design preset track under the constraint of the double-side limiting strip 3, effectively avoiding the demolding obstruction caused by deviation or inclination. The movement of the slider block seat 7 in this stage finally realizes the complete core-pulling of the oil outlet hole insert pin 11 and the oil inlet hole insert pin 12, ensuring the complete demolding of the injection molded part.

[0032] Through the above structure combination and cooperation mode, the utility model effectively solves the problems of difficult demolding of the reverse buckle structure in the multi-inlet and outlet oil port filter seat injection mold, assembly error and poor sealing caused by flash and gap after forming, reduces the cost of manual trimming, improves the reliability and service life of the mold operation. The whole core-pulling and demolding mechanism is designed ingeniously, the cooperation between structures is orderly and the movement is accurate, which ensures the stable execution of high-precision forming and efficient demolding operation, and has remarkable practical value and popularization prospect.

[0033] In the embodiment, the oil outlet hole insert pin 11 and the oil inlet hole insert pin 12 are detachably connected to the slider block seat 7 through bolt connection. The oil outlet hole insert pin 11 and the oil inlet hole insert pin 12 are detachably installed on the slider block seat 7 through bolt connection, which is beneficial to quick replacement when the insert pin is worn or damaged, avoids overall disassembly of the mold, reduces the maintenance difficulty and labor cost, and can realize flexible replacement of different structure insert pins, improving the mold universality and maintenance efficiency.

[0034] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
