Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.

As shown in fig. 1 to 4, the in-mold die of the present embodiment includes a first die structure 10, a second die structure 20, and an oil-way plate structure 30. The first mold structure 10 and the second mold structure 20 are stacked, and the oil circuit board structure 30 is located at the circumferential outside of the first mold structure 10. The oil passage plate structure 30 includes an oil passage plate 31, an oil passage 32, a seal 33, and an oil feed bolt joint 34, the oil passage 32 is a communication hole penetrating a first side of the oil passage plate 31 and a second side of the oil passage plate 31, an inlet of the oil passage 32 is located at the first side of the oil passage plate 31, an outlet of the oil passage 32 is located at the second side of the oil passage plate 31, the first side of the oil passage plate 31 faces away from the first mold structure 10, the oil feed bolt joint 34 is detachably mounted at the inlet of the oil passage 32, and the seal 33 is pressed between the oil feed bolt joint 34 and the oil passage plate 31.

By applying the technical scheme of the embodiment, the sealing piece 33 is extruded between the oil inlet bolt joint 34 and the oil circuit board 31, so that the phenomenon of oil leakage of the in-mold cutting die is avoided. In addition, the first side of the oil circuit board 31 faces away from the first mold structure 10, and the inlet of the oil circuit 32 is located on the first side of the oil circuit board 31, so that the acting force can be conveniently applied to the oil inlet bolt joint 34, namely, when oil leakage occurs, the oil inlet bolt joint 34 can be screwed in. The oil leakage problem of the in-mold cutting die can be effectively prevented by the two means. The technical scheme of the embodiment effectively solves the problem of oil leakage at the joint of the oil inlet bolt joint 34 and the oil circuit board 31 of the internal mold in the prior art.

It should be noted that the in-mold cutting die includes a die main body and a cutter disposed in the die main body, the cutter is movably disposed in the die main body, and the cutter is communicated with the oil path 32, so that the oil in the oil path 32 drives the cutter to work, and the internal structure such as the oil path and the like will not be described herein.

As shown in fig. 3 and fig. 4, in the technical solution of this embodiment, the oil inlet bolt joint 34 includes an external thread section 341, a limiting section 342 and a connecting section 343, the sealing member 33 is a metal sealing ring, the external thread section 341 and the connecting section 343 are respectively located at two sides of the limiting section 342, the metal sealing ring is sleeved on the circumferential outer side of the external thread section 341, and the metal sealing ring is propped between the oil circuit board 31 and the limiting section 342. The metal seal ring is used as the seal member 33 to effectively avoid leakage occurring when a rubber or the like is used as the seal pad.

The material of the metal seal ring is red copper. The sealing member 33 made of red copper has a good sealing effect on hydraulic oil. Other materials, such as rubber materials, can penetrate the rubber material and affect the seal. The outer diameter of the limiting section 342 is larger than the outer diameter of the externally threaded section 341, so that a force is easily applied. The oil feed bolt joint 34 is provided with an arrow, the direction of which is from the connecting section 343 to the externally threaded section 341.

As shown in fig. 3, in the technical solution of the present embodiment, the outer surface of the limiting section 342 is hexagonal. The above structure ensures that the outer surface of the oil feed bolt joint 34 has a force application surface, which is more convenient for force application. It should be noted that the outer surface of the limiting section 342 may be other polygons.

In the technical solution of this embodiment, the oil inlet bolt joint 34 further includes an arrow mark, the arrow mark is disposed on the outer surface of the limiting section 342, and the direction of the arrow mark is from the connecting section 343 to the external thread section 341. The above structure allows a user to visually know the direction in which the oil feed screw joint 34 is installed. This avoids misdirection of the oil feed bolt joint 34.

As shown in fig. 3, in the technical solution of the present embodiment, the diameter of the external thread segment 341 is smaller than the diameter of the connection segment 343. The structure can play a good foolproof role. For example, if the oil feed bolt joint 34 is reversed, the situation of no connection occurs, so that the situation of reversed connection of the oil feed bolt joint 34 can be effectively prevented.

As shown in fig. 1, in the technical solution of this embodiment, the first side of the oil circuit board 31 has a groove, the bottom surface of the groove is a plane, and the inlet of the oil circuit 32 is located at the bottom surface of the groove. The recess is provided for easy positioning, the inlet of the oil passage 32 is located at the bottom surface of the recess, and the bottom surface of the recess is a plane for easy sealing.

As shown in fig. 1, in the technical solution of the present embodiment, the depth of the groove is smaller than the length of the limiting section 342. This allows the spacing segment 342 to protrude from the recess, i.e., the spacing segment 342 is exposed to the outside of the recess for a distance that facilitates application of a force to the oil feed bolt joint 34. It is convenient to apply force when using a wrench to apply force to the spacing segment 342.

As shown in fig. 4, in the technical solution of this embodiment, the oil inlet bolt joint 34 further includes a filter plate 344, wherein a circumferential outer side of the filter plate 344 is connected to an inner wall of the limiting section 342, and a screen hole is provided on the filter plate 344. The filter plate 344 is arranged to effectively filter particulate impurities contained in the hydraulic oil, so as to effectively avoid the particulate impurities from damaging the in-mold cutting die.

The slag discharge hole 345 is a threaded hole, and the oil inlet bolt joint 34 further comprises a blocking wire which is matched with the slag discharge hole 345. The arrangement of the slag hole 345 has two functions: 1. impurities can be discharged without disassembling the oil feed bolt joint 34 and the oil passage plate 31; 2. whether the hydraulic oil external pipe is clear or not can be checked through the drain hole 345. The blocking wire may be a valve, that is, the valve is disposed at the position of the slag discharging hole 345, and the slag is discharged or an external pipeline is detected by opening or closing the valve. It should be noted that, the filter plate 344 is disposed obliquely from top to bottom, so that the impurities can slide down to the slag discharging holes 345 under the action of gravity, and then the impurities can be more conveniently discharged.
