Description

Technical Field

[0001] This utility model relates to the field of core-pulling structure technology, and in particular to a core-pulling assembly with multiple insert rods. Background Technology

[0002] In conventional die-casting molds, insert rod structures are usually chosen to assist in the forming of holes on the product. Conventional holes are installed in one direction, so the insert rods used for forming can be directly installed on the core-pulling block. However, when there are angled holes on the product, due to the different inclination directions, multiple different core-pulling structures need to be designed to pull the holes individually. This will greatly increase the cost of the mold, and the entire mold does not have much space to arrange too many independent hole core-pulling structures. To solve the above problems, the core-pulling components need to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a core-pulling assembly with multiple insert rods, which has the characteristics of saving internal space of the mold, reducing overall cost, and avoiding interference between core pullers.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a core-pulling assembly with multiple insert rods is provided, including a slider seat, a core-pulling block and a first insert rod core. The core-pulling block is installed on the left end of the slider seat, and a main hydraulic cylinder that connects the main shaft and the slider seat is installed on the right side of the slider seat. A first insert rod core with its left end tilted backward is installed at the front end of the middle part of the slider seat. A second insert rod core with its pin end facing left is installed at the rear end of the middle part of the slider seat. A third insert rod core with its lower end tilted to the left is installed at the upper left end of the slider seat. The core-pulling ends of the first insert rod core, the second insert rod core and the third insert rod core all pass through the slider seat and the core-pulling block.

[0005] The third core-pulling mechanism includes a core-pulling seat, a third core-pulling rod, and a transmission block. The core-pulling seat is embedded in the upper surface of the slider seat. The core-pulling seat has a slanted hole structure with the left end tilted downwards. The core-pulling seat has a docking base that can move up and down. The transmission block is installed in the slanted hole structure of the core-pulling seat. The lower end of the transmission block extends from the left end of the slanted hole structure. The third core-pulling rod, which is tilted, is installed on the lower end of the transmission block. A pull rod that passes through the transmission block is installed on the lower end of the docking base. The lower end of the pull rod is tilted to the right.

[0006] When the docking base rises, the pull rod at the lower end of the docking base will pull the transmission block and the third core-pulling rod, so that the transmission block and the third core-pulling rod can rise along the inclined hole structure.

[0007] This technical solution ensures that the holes on the product are formed by installing independently operable first, second, and third core-pulling rods. It also simplifies the core-pulling structure, saves space within the mold, and reduces manufacturing costs. Furthermore, a docking base is installed to connect with the upper mold structure, facilitating the lifting of the docking base after mold opening. A pull rod at the lower end of the docking base drives a transmission block, which in turn moves the third core-pulling rod, allowing it to detach from the product.

[0008] As a supplement to this technical solution, the slider seat is provided with an upwardly protruding mounting platform, and the right side of the mounting platform is provided with a flush mating surface. The four corners of the mating surface are provided with mating holes, and the center of the mating surface is provided with an insertion interface that matches the second insertion rod core puller.

[0009] In this technical solution, an installation platform is set up to facilitate the connection of the second insert rod core pulling. The second insert rod core pulling includes a second core pulling rod and a second core pulling cylinder. The main shaft of the second core pulling cylinder is connected to the second core pulling rod, and the second core pulling cylinder is installed on the installation platform.

[0010] As a supplement to this technical solution, the front and rear sides of the transmission block are provided with inclined protrusions, and the side wall of the inclined hole structure of the core-pulling seat is provided with a guide groove structure that matches the inclined protrusions.

[0011] In this technical solution, inclined protrusions and guide grooves are used to facilitate the smooth movement of the transmission block.

[0012] As a supplement to this technical solution, a guide bolt for inserting into the upper part of the inclined hole structure is installed on the right end of the core-pulling seat, and a bolt guide groove corresponding to the guide bolt is provided on the lower right end of the transmission block.

[0013] In this technical solution, guide bolts and bolt guide grooves are installed to facilitate the smooth movement of the transmission block.

[0014] As a supplement to this technical solution, the transmission block is provided with a transmission inclined hole that matches the lower end of the lever. In this technical solution, the transmission inclined hole is used to facilitate transmission matching with the lower end of the lever. When the lever moves upward, it is used to facilitate the transmission block to tilt upward.

[0015] As a supplement to this technical solution, the first core-pulling rod includes a double-rod hydraulic cylinder, a main shaft, a connecting sleeve, and a first core-pulling rod. The double-rod hydraulic cylinder has two main shafts located at the left and right ends of the cylinder. The main shaft at the left end is connected to the first core-pulling rod via the connecting sleeve. The main shaft at the right end has an upwardly extending connecting rod. Two first contact switches with forward-facing contact heads are installed side by side on the upper surface of the cylinder body of the double-rod hydraulic cylinder. Two upwardly extending docking seats are provided at the front of the upper surface of the cylinder body of the double-rod hydraulic cylinder. A transverse transmission shaft that slides left and right is installed between the two docking seats. The right end of the transverse transmission shaft is connected to the upper end of the connecting rod. Two trigger rings corresponding to the first contact switches are welded side by side on the connecting rod.

[0016] As a supplement to this technical solution, the main cylinder includes a cylinder body structure, a docking spindle, and a spindle coupling. The docking spindle is located at the left end of the cylinder body structure, and a spindle coupling is installed at the end of the docking spindle. An upwardly extending transmission sleeve docking seat is installed on the rear side of the spindle coupling. A transmission sleeve extending horizontally to the right is installed at the upper end of the transmission sleeve docking seat. A protective shell is installed on the cylinder body structure. Two rearward-facing second contact switches are installed side by side on the bottom front end of the protective shell. The transmission sleeve is inserted into the protective shell. A transmission sleeve guide shaft matching the transmission sleeve is installed inside the protective shell. Two trigger rings matching the second contact switches are installed side by side on the transmission sleeve.

[0017] In this technical solution, a protective shell is installed to protect the second contact switch and prevent it from being contaminated by the external environment. A main shaft coupling is installed to facilitate connection with the transmission sleeve docking seat. When the docking main shaft extends or retracts, it can drive the transmission sleeve docking seat to connect. Through the transmission sleeve and the transmission sleeve guide shaft, the transmission sleeve can move back and forth on the transmission sleeve guide shaft, thereby enabling the trigger ring to contact the second contact switch.

[0018] As a supplement to this technical solution, the protective shell is equipped with a flip cover, the rear end of which is connected to the protective shell via a hinge structure, a locking pin is installed on the front of the protective shell, and a pin insertion sleeve corresponding to the locking pin is installed on the flip cover.

By installing a first, second, and third insert rod core-pulling assembly that can operate independently, it ensures that the holes on the product are formed. At the same time, it simplifies the core-pulling structure, saves space within the mold, and reduces the manufacturing cost of the core-pulling structure. Furthermore, by installing a docking base for docking with the upper mold structure, it is convenient to lift the docking base after the mold is opened. The pull rod at the lower end of the docking base can drive the transmission block, which can drive the third core-pulling rod to move, thereby realizing the third core-pulling rod detaching from the product. It has the characteristics of saving internal mold space, reducing overall cost, and avoiding interference between core-pulling components. Attached Figure Description
