A positioning hole corresponding to the pin hole is provided inside the mold core. The positioning hole is connected to the pin hole. A pin passes through the inside of the pin hole, and both ends of the pin hole are inserted into the inside of the positioning hole.

[0008] Preferably, the connector includes an interface groove on one side of both the half-piece insert and the insert body, and a dovetail block is fixedly installed at the bottom of the half-piece insert. The mounting groove has a dovetail groove corresponding to the dovetail block inside.

[0009] Preferably, the top of the half-piece insert is rounded, and the slope of the positioning hole and the interface groove are both set to 5°~10°.

[0010] Preferably, the interface between the half-piece insert and the insert body is either wavy or sawtooth-shaped.

[0011] Preferably, both the main body of the insert and the half-insert are beryllium copper components.

[0012] Preferably, the diameter of the positioning hole matches the diameter of the pin hole, and the pin hole penetrates both the positioning hole and the pin hole.

[0013] The beneficial effects of this utility model are:

[0014] The insert body and half insert are installed using connectors. The insert body and half insert are designed with mutually matching mounting grooves to achieve self-locking. At the same time, the insert body and half insert are pressed together from the side of the mold core with pins to provide additional locking force and greatly enhance the overall rigidity. When there are design changes or damage to the insert glue position, and timely delivery is required, but the production time of new inserts is long, the combination of insert body and half insert can be used to solve the problems of urgent orders and repair of large insert damage.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a detachable half-section insert includes a mold core 1, an insert body 2 is snapped into the inside of the mold core 1, and an installation groove 11 is provided inside the insert body 2, and a half-section insert 3 is snapped into the inside of the installation groove 11.

[0022] A connector 4 is provided between the insert body 2 and the half insert 3, and a pin hole 7 is provided inside the insert body 2 and the half insert 3. A positioning hole 5 corresponding to the pin hole 7 is provided inside the mold core 1. The positioning hole 5 is connected to the pin hole 7. A pin 6 passes through the inside of the pin hole 7, and both ends of the pin hole 7 are inserted into the inside of the positioning hole 5.

[0023] In this embodiment, the insert body 2 and the half insert 3 are first installed by the connector 4. The mounting grooves 11 designed on the insert body 2 and the half insert 3 are designed to cooperate with each other, and the mounting grooves 11 are used to achieve self-locking. At the same time, the insert body 2 and the half insert 3 are pressed tightly from the side on the mold core 1 by the pin 6. When the design changes or the glue position of the insert is damaged, and it is necessary to deliver in time, and the new insert takes a long time to manufacture, the combination of insert body 2 and half insert 3 can be used to solve the problems of urgent orders and repair of large insert damage.

[0024] As one implementation method, such as Figure 2 As shown, the connector 4 includes an interface groove 8 on one side of both the half-insert 3 and the insert body 2. A dovetail block 9 is fixedly installed at the bottom of the half-insert 3, and a dovetail groove 10 corresponding to the dovetail block 9 is opened inside the mounting groove 11.

[0025] In this embodiment, when the half-piece insert 3 is installed into the mounting groove 11 of the insert body 2, the bottom of the half-piece insert 3 is designed as a dovetail block 9, which combines with the dovetail groove 10 in the mounting groove 11, which can effectively prevent lateral displacement and enhance impact resistance.

[0026] As one implementation method, such as Figure 2 As shown, the top of the half-piece insert 3 is rounded, and the slope of the positioning hole 5 and the interface groove 8 are both set to 5°~10°.

[0027] In this embodiment, both the half-insert 3 and the insert body 2 are designed with mutually cooperating inclined surfaces, which are used to achieve self-locking.

[0028] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the interface between the half-piece insert 3 and the insert body 2 is set to either a wavy shape or a sawtooth shape.

[0029] In this embodiment, the mating surface between the half-insert 3 and the insert body 2 is processed into a fine wave shape or sawtooth shape, which can make the fit tighter and reduce the possibility of slight displacement.

[0030] As one implementation method, such as Figure 1 As shown, both the main body 2 and the half-piece 3 are beryllium copper components.

[0031] In this embodiment, the insert is made of beryllium copper, a material with excellent thermal conductivity. It can quickly conduct heat to the cooling system of the mold template, thus alleviating the problem of local overheating to a certain extent.

[0032] As one implementation method, such as Figure 2 and Figure 3 As shown, the diameter of the positioning hole 5 matches the diameter of the pin hole 7, and the pin hole 7 penetrates the interior of both the positioning hole 5 and the pin hole 7.

[0033] In this embodiment, a pin 6 is used to pass through the positioning hole 5 and the pin hole 7 on the side of the mold core 1 to press the insert body 2 and the half insert 3 together, providing additional locking force and greatly enhancing the overall rigidity.

[0034] Working principle: In use, the main body 2 and the half-insert 3 are first installed through the connector 4. The mounting grooves 11 designed on the main body 2 and the half-insert 3 are designed to cooperate with each other, and the mounting grooves 11 achieve self-locking. At the same time, when the half-insert 3 is installed into the mounting groove 11 of the main body 2, the bottom of the half-insert 3 is designed as a dovetail block 9, which combines with the dovetail groove 10 in the mounting groove 11, which can effectively prevent lateral displacement and enhance impact resistance.

[0035] After installation, the insert body 2 and half insert 3 are pressed together from the side on the mold core 1 with pins 6 to provide additional locking force and greatly enhance the overall rigidity. When design changes or insert glue position is damaged, timely delivery is required and the new insert takes a long time to manufacture, the combination of insert body 2 and half insert 3 can be used to solve urgent orders and repair of large insert damage.
