[0026] A first forming cavity part 101 and a clamping part groove 9 are arranged above the first core seat 1, and the first forming cavity part 101 communicates with the clamping part groove 9 in a circumferential manner. An end face opening part 102 is arranged below one side of the first core seat 1, and one end of the first positioning frame 3 is fixedly connected inside the end face opening part 102.

[0027] Furthermore, the middle part of the first telescopic cylinder 5 is fixedly connected inside the outer end of the first positioning frame 3, and the telescopic end of the first telescopic cylinder 5 is arranged inside the first positioning frame 3. The telescopic end of the first telescopic cylinder 5 is fixedly connected to the outer end of the core-pulling component 8, and a limiting through-hole part 801 is arranged in the middle of the core-pulling component 8.

[0028] Furthermore, a positioning through-hole part 12 is arranged inside one side of the first core seat 1, and the outer port of the positioning through-hole part 12 is arranged in the middle of the end face opening part 102. At the same time, the positioning through-hole part 12 is arranged below the first forming cavity part 101, and the core-pulling component 8 is inserted and slidably connected inside the positioning through-hole part 12.

[0029] The core-pulling component 8 is inserted into the first core seat 1, and the core-pulling component 8 is controlled by the first telescopic cylinder 5 and can move inside the first core seat 1. In this way, the core-pulling component 8 can position other components inside the entire mold. At the same time, after the core-pulling component 8 is pulled out, other components can be demolded and removed.

[0030] A positioning groove part 11 and an internal through-hole part 103 are respectively arranged on the side surface of one end of the first core seat 1, and the limiting block 7 is inserted and slidably connected inside the positioning groove part 11.

[0031] Furthermore, the second positioning frame 4 is fixedly connected to the other side surface of one end of the first core seat 1, and the second positioning frame 4 is arranged outside the internal through-hole part 103. The middle part of the outer end of the second positioning frame 4 is fixedly connected to the middle part of the second telescopic cylinder 6.

[0032] Further, the telescopic end of the second telescopic cylinder 6 is placed inside the second positioning frame 4, and one end of the limiting rod 13 is fixedly connected to the telescopic end of the second telescopic cylinder 6. At the same time, the limiting rod 13 is inserted into the built-in through-hole part 103.

[0033] Furthermore, the inner end of the limiting rod 13 is inserted into the limiting through-hole part 801, and the inner end of the limiting rod 13 is fixedly connected to the inner side of the limiting block 7. At the same time, the limiting block 7 is slidably connected inside the limiting through-hole part 801.

[0034] On one side surface of one end of the first core seat 1, there are provided a second positioning frame 4 and a second telescopic cylinder 6. The telescopic end of the second telescopic cylinder 6 is provided with a limiting rod 13. By connecting the limiting rod 13 to the limiting block 7 on the other side of the first core seat 1, under the action of the second telescopic cylinder 6, the limiting block 7 can be inserted into the core-pulling assembly 8. In this way, when the mold is closed, the core-pulling assembly 8 is made stable. At the same time, the limiting rod 13 and the limiting block 7 can be disconnected automatically, and the limiting block 7 withdraws from the core-pulling assembly 8 under an external force.

[0037] After the first molding cavity part 101 provided on the first core seat 1 and the second molding cavity part 201 provided on the second core seat 2 are combined, the cavity completed inside the mold is formed. At the same time, the second core seat 2 can be moved away when the mold is opened.

[0038] Working principle:

[0039] Above the first mold core base 1, within the clamping part groove 9, below the second mold core base 2, the two are integrated, such that the first molding cavity part 101 provided on the first mold core base 1 and the second molding cavity part 201 provided on the second mold core base 2 are combined. At one end of the first mold core base 1, there is a first positioning frame 3 and a first telescopic cylinder 5, and the core pulling assembly 8 connected to the first telescopic cylinder 5 is respectively inserted into the first mold core base 1 and the second mold core base 2. When the mold is closed, the second mold core base 2 is fixed on the first mold core base 1 by the core pulling assembly 8. On the side surface of one end of the first mold core base 1, there is a second positioning frame 4 and a second telescopic cylinder 6, and the second telescopic cylinder 6 is connected to the limit rod 13. Inside the other side surface of one end of the first mold core base 1, there is a limit block 7, and the limit block 7 and the limit rod 13 can be connected and disconnected. When the mold is closed, the limit rod 13 is driven to insert into the limit block 7, and then the limit rod 13 is pulled back to insert a part of the limit block 7 into the middle of the core pulling assembly 8, making the core pulling assembly 8 stable. When the mold is opened, the limit rod 13 releases the limit block 7, and the limit block 7 retracts into the positioning groove part 11 under the external force, so that the core pulling assembly 8 is pulled back a certain distance by the first telescopic cylinder 5 and exits from the positioning groove part 10 of the second mold core base 2, so that the second mold core base 2 can be moved away, and it prevents the movement of the second mold core base 2 during mold opening from affecting the quality of the product part.
