Description

Technical Field

[0001] This utility model belongs to the field of die casting mold core pulling, and specifically relates to a die casting mold core pulling mechanism. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. In the die casting mold production process, in order to meet the requirements of stable and continuous use of various products, a core-pulling mechanism is often used. Existing core-pulling mechanisms include inclined guide post core-pulling mechanisms, bent pin core-pulling mechanisms, hydraulic core-pulling mechanisms, and manual core-pulling mechanisms.

[0003] According to Chinese Patent No. CN220049974U, a core-pulling mechanism for die-casting molds is disclosed, including a core-pulling mechanism body. A mounting plate is provided at the right end of the core-pulling mechanism body. A fixing plate is connected to the right side of the mounting plate. A telescopic mechanism is provided on the right side of the fixing plate. The telescopic mechanism is installed on the inner wall of the die-casting mold frame. Two insert plates are provided on the right side of the mounting plate. Slots corresponding to the insert plates are opened on the wall of the fixing plate. Limiting holes are opened on the walls of the two insert plates. Limiting pins are inserted into the limiting holes. The installation position of the core-pulling mechanism can be restricted by the cooperation of the mounting plate, fixing plate, insert plates, and slots. The position of the insert plates can be fixed by the cooperation of the limiting holes and limiting pins, thereby completing the installation of the core-pulling mechanism. The mounting cavity, spring, limiting plate, positioning block, and positioning hole ensure that the position of the limiting pin is fixed.

[0004] As can be seen from the above structure, the installation position of the core-pulling mechanism can be restricted by the cooperation of the mounting plate, fixing plate, insert plate, and slot. The position of the insert plate can be fixed by the cooperation of the limiting hole and the limiting pin, thereby completing the installation of the core-pulling mechanism. The setting of the mounting cavity, spring, limiting plate, positioning block, and positioning hole can ensure that the position of the limiting pin is fixed. However, the mold core-pulling structure is processed by high-precision equipment, and the above structure cannot guarantee its stability by plugging and connecting, which reduces the practicality of the device and the accuracy of the mold. Moreover, the die-casting mold is used frequently and the temperature rises rapidly. The core-pulling mechanism installed in the die-casting mold is prone to expansion due to heat, making it difficult to push and pull smoothly. This can easily lead to burn and jamming problems when the core is sliding. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A die-casting mold core-pulling mechanism includes a mounting plate. An electric push rod is fixedly connected to the front of the mounting plate. An installation assembly is fixedly connected to the other end of the electric push rod. A mold base is fixedly connected to the other end of the installation assembly. A mold core is fixedly connected to the other end of the mold base. A cooling assembly is disposed inside the mold core.

Locking holes are formed on the outer surface of each insertion pin. A bevel gear is fixedly connected to the outer surface of each mounting screw. A rotating handle is fixedly connected to the other end of the mounting screw through the mounting seat.

[0008] As a preferred technical solution, the cooling component includes a water inlet pipe disposed on the back of the mounting plate, a drain pipe fixedly connected to the back of the mounting plate, and a telescopic pipe fixedly connected to the other end of both the water inlet pipe and the drain pipe through the mounting plate, and a connecting pipe fixedly connected to the other end of the telescopic pipe.

[0009] As a preferred technical solution, a threaded mounting head is fixedly connected to the other end of the connecting pipe, a cooling pipe is fixedly connected inside the mold core, and threaded mounting cylinders are fixedly connected to both ends of the cooling pipe through the mold base. The threaded mounting cylinders and the threaded mounting head are threadedly connected to each other.

[0010] As a preferred technical solution, the front of the mounting plate is provided with a hidden groove, the inside of the hidden groove is provided with a mounting through hole, a mounting screw is inserted into the mounting through hole, and the mounting screw passes through the mounting through hole and is threadedly connected to the base layer.

[0011] As a preferred technical solution, the other end of the electric push rod is fixedly connected to a fixed plate. The outer surface of the fixed plate is provided with a fixed through hole. A fixing screw is inserted into the fixed through hole and is fixedly connected to the mounting component through the fixed through hole.

[0012] As a preferred technical solution, a connecting groove is provided on the outer side of the mounting plate, a connecting through hole is provided inside the connecting groove, a connecting screw is inserted into the connecting through hole, and the other end of the connecting screw passes through the connecting through hole and is threadedly connected to the mold seat.

[0013] As a preferred technical solution, the upper end of the mounting base is fixedly connected to a limiting plate, and a limiting groove is formed on the outer surface of the limiting plate, and the limiting groove is inserted into the insertion post.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the installation components of this utility model allow for easy installation of the mold core. When the mold core needs to be installed, the insert pin is inserted into the limiting groove. Then, by turning the rotating handle, the installation screw is rotated. The rotation of the installation screw causes multiple bevel gears to move the threaded component. This movement of the threaded component causes the connecting plates to move closer together. Simultaneously, the moving connecting plates cause the locking pin to move into the locking hole. Once the locking pin and locking hole are engaged, the mold core can be installed. Furthermore, the clamping and locking installation method improves stability, thus preventing parts processing failures due to poor mold core installation stability.

[0016] Secondly, this utility model, through its cooling component, connects the inlet pipe to the inlet end of the water circulation equipment and the outlet pipe to the outlet end of the water circulation equipment. The coolant from the water cooling equipment is then transported to the inside of the connecting pipe through the telescopic pipe. After the coolant enters the inside of the connecting pipe, it enters the inside of the cooling pipe through the threaded mounting head and threaded mounting cylinder. This allows the coolant to cool the mold core after entering the cooling pipe, thus preventing sticking during core pulling. At the same time, the cooling component increases the processing efficiency of the parts. Attached Figure Description

[0024] refer to Figure 1 , Figure 2 and Figure 4The cooling component 6 includes a water inlet pipe 61 disposed on the back of the mounting plate 1, a drain pipe 62 fixedly connected to the back of the mounting plate 1, and a telescopic pipe 63 fixedly connected to the other end of both the water inlet pipe 61 and the drain pipe 62 through the mounting plate 1. A connecting pipe 64 is fixedly connected to the other end of the telescopic pipe 63, and a threaded mounting head 65 is fixedly connected to the other end of the connecting pipe 64.

The threaded mounting cylinders 67 and the threaded mounting head 65 are threadedly connected to each other. By connecting the water inlet pipe 61 to the water inlet of the water circulation equipment and the drain pipe 62 to the water outlet of the water circulation equipment, the coolant of the water cooling equipment is transported to the inside of the connecting pipe 64 through the telescopic pipe 63. After the coolant enters the inside of the connecting pipe 64, it enters the inside of the cooling pipe 66 through the threaded mounting head 65 and the threaded mounting cylinder 67, thereby achieving a cooling effect on the mold core 5 after the coolant enters the inside of the cooling pipe 66.

[0025] refer to Figure 2 The mounting plate 1 has a hidden groove 10 on its front side, and a mounting through hole 11 is provided inside the hidden groove 10. A mounting screw 12 is inserted into the mounting through hole 11 and is threaded through the mounting through hole 11 to the base layer. By placing the mounting plate 1 in a suitable position, and then threading the mounting screw 12 through the mounting through hole 11 to the mounting base layer of the mounting plate 1, the core pulling mechanism can be installed.

The limiting groove 14 allows the insert post 37 to be inserted into the limiting groove 14, making the installation of the mold core 5 through the mounting component 3 more stable. The limiting groove 14 and the limiting post 37 of the polygonal limiting groove make the installation effect of the mounting component 3 better.

[0029] Operating principle and advantages: During use, the fixing screw 9 and fixing through hole 8 allow for the installation of the mounting component 3 and the electric push rod 2. The connecting screw 17 and connecting through hole 16 facilitate the installation of the mold base 4 and the mounting component 3. Finally, by placing the mounting plate 1 in a suitable position and threading the mounting screw 12 through the mounting through hole 11 to the mounting base of the mounting plate 1, the core-pulling mechanism can be installed. When installing the mold core 5, the insert 37 is inserted into the limiting groove 14. Tightening the rotating handle 322 drives the mounting screw 33 to rotate. The rotation of the mounting screw 33, under the action of multiple bevel gears 311, drives the threaded component 34 to move. The movement of the threaded component 34 allows... The connecting plates 35 are brought together, causing the locking pins 36 to move into the locking holes 38 as the connecting plates 35 move. After the locking pins 36 and locking holes 38 are engaged, the mold core 5 can be installed. After fixing, the water inlet pipe 61 is connected to the water inlet of the water circulation equipment, and the drain pipe 62 is connected to the drain of the water circulation equipment. The coolant from the water cooling equipment is then transported to the inside of the connecting pipe 64 through the telescopic pipe 63.

This coolant can cool the mold core 5 after entering the inside of the cooling pipe 66, thus preventing sticking during core pulling. At the same time, the cooling component 6 increases the processing efficiency of the parts.
