[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a plastic mold inclined guide column positioning structure includes a mold frame 1, and the mold frame 1 is respectively provided with a through groove 3 and a positioning groove 4, the through groove 3 and the positioning groove 4 are connected, and an inclined guide column 5 is inserted into the positioning groove 4, and a main slider 2 is provided on the outer peripheral sliding sleeve of the inclined guide column 5, and the bottom of the main slider 2 is clamped with the mold frame 1;

[0023] A notch 9 is formed on the outside of the inclined guide column 5 , a positioning plate 10 is clamped inside the notch 9 , a fastening screw 11 eccentrically penetrates the inside of the positioning plate 10 , and the fastening screw 11 is installed in the through slot 3 .

[0024] In this embodiment, before the main slider 2 is installed with the mold frame 1, the notch 9 on the outside of the inclined guide column 5 is brought into contact with the positioning plate 10, and the inclined guide column 5 and the positioning plate 10 are simultaneously inserted into the inside of the positioning groove 4 and the through groove 3, and then the fastening screw 11 is eccentrically passed through the positioning plate 10 and installed inside the through groove 3. With the combination of the eccentric positioning plate 10 and the notch 9, the main slider 2 can be quickly inserted, and while maintaining the stability of the inclined guide column 5, it is convenient for quick disassembly and assembly during mold closing and demolding.

[0025] As an implementation method, Figure 4 As shown, the oblique guide post 5 is composed of a guide post head 6 and a guide post rod 7, and the guide post head 6 and the guide post rod 7 are connected by threads.

[0026] In this embodiment, the length of the integral oblique guide column 5 can be adjusted by threaded connection between the guide column head 6 and the guide column rod 7, so as to facilitate the installation of different mold frames 1 and different main slide blocks 2 and improve applicability.

[0027] The length of the guide post head 6 is combined with the main slider 2, and the guide post rod 7 is inserted into the through slot 3. Since the length of the guide post head 6 is greater than the length of the guide post rod 7, it is convenient to take out the entire inclined guide post 5.

[0028] As an implementation method, Figure 2 , Figure 3 and Figure 4 As shown, the top of the guide pin head 6 is hemispherical, a threaded hole is provided on the top of the guide pin head 6 , and a notch 9 is provided at the bottom of the guide pin head 6 .

[0029] In this embodiment, the top of the guide pin head 6 is hemispherical. When the main slider 2 contacts the guide pin head 6, scratches on the inside of the main slider 2 are prevented and the main slider 2 can be quickly inserted. At the same time, the threaded hole on the top of the guide pin head 6 facilitates the connection between the other part of the mold frame (1) and the threaded hole after the entire mold is closed.

[0030] As an implementation method, Figure 3As shown, a through groove 8 corresponding to the inclined guide column 5 is provided inside the main sliding block 2 , the through groove 8 is provided at an angle, and the positioning groove 4 is connected to the through groove 8 .

[0031] In this embodiment, the inclined through groove 8 is combined with the positioning groove 4, the inclined guide column 5 is first inserted into the positioning groove 4, and then the through groove 8 in the main slider 2 is sleeved on the inclined guide column 5, so that the main slider 2 and the mold frame 1 are kept overlapped, thereby increasing the tightness of the connection between the main slider 2 and the mold frame 1.

[0032] As an implementation method, Figure 4 As shown, the positioning plate 10 is a circular structure, and the size of the positioning plate 10 is matched with the size of the through slot 3.

[0033] In this embodiment, the circular positioning plate 10 is engaged with the notch 9 on the inclined guide column 5, and the positioning plate 10 is connected to the through slot 3 by means of the fastening screws 11, so as to ensure the stability of assembly and disassembly during the mold closing or demolding process.

[0034] Working principle: When in use, before the main slider 2 is installed with the mold frame 1, the notch 9 outside the inclined guide column 5 is in contact with the positioning plate 10, and the inclined guide column 5 and the positioning plate 10 are simultaneously inserted into the inside of the positioning groove 4 and the through groove 3, and the inclined through groove 8 is combined with the positioning groove 4. The inclined guide column 5 is first inserted into the positioning groove 4, and then the through groove 8 in the main slider 2 is sleeved on the inclined guide column 5. The main slider 2 and the mold frame 1 are kept overlapped, thereby increasing the tightness of the connection between the main slider 2 and the mold frame 1;

[0035] Then, the fastening screw 11 is eccentrically passed through the positioning plate 10 and installed inside the through groove 3. With the combination of the eccentric positioning plate 10 and the notch 9, the main slider 2 can be quickly inserted, which not only maintains the stability of the inclined guide column 5, but also facilitates quick disassembly and assembly during mold closing and demolding.
