The lower template 1 is also provided with a multi-point glue feeding structure.

[0027] In this utility model, two forming cavities 2 on the left and right sides of the slope can injection mold two headlight decoration frame products at one time. The double insert integrated core-pulling assembly 5 can achieve the core-pulling of two inserts at one time, which can reduce the number of core-pulling mechanisms on the mold and thus reduce the mold cost. After the product is injection molded, when the mold is opened, the upper template moves upward, and the automatic core-pulling can be realized through the first side core-pulling assembly 3, the second side core-pulling assembly 4 and the double insert integrated core-pulling assembly 5. The multi-point gating structure can increase the injection efficiency.

[0028] Specifically, the multi-point gating structure includes a first gating groove 6 arranged between the two forming cavities 2. The two sides of the first gating groove 6 are respectively connected to the inner sides of the two forming cavities 2 through first gating runners 7. The first gating groove 6 and the first gating runners 7 are recessed and arranged at the top of the slope. The multi-point gating structure further includes four second gating grooves 8 distributed in pairs on the outer sides of the two forming cavities 2. The second gating grooves 8 are connected to the outer sides of the forming cavities 2 through second gating runners 9. Through the first gating groove 6 and the first gating runners 7, the plastic can be injected into the forming cavity from the inner side of the forming cavity. Through the second gating grooves 8 and the second gating runners 9, the plastic can be injected into the forming cavity from the outer side of the forming cavity. The synchronous injection of the inner and outer sides of the forming cavity can improve the injection efficiency.

[0029] Specifically, the double insert integrated core-pulling assembly 5 includes a core-pulling slider 10 slidably arranged on the lower template 1. The upper side of the inner end of the core-pulling slider 10 is fixedly connected with an upper insert 11 inserted into the forming cavity 2. The lower side of the inner end of the core-pulling slider 10 is provided with a lower insert 12 horizontally penetrating the lower template 1 and inserted into the forming cavity 2. The lower insert 12 is cylindrical. The upper insert 11 and the lower insert are respectively arranged on the upper and lower sides of the core-pulling slider and are parallel. When the core-pulling slider moves away from the forming cavity, the synchronous core-pulling of the upper insert 11 and the lower insert can be realized.

[0030] Specifically, the double insert integrated core-pulling assembly 5 further includes a side driving rod 13 obliquely fixed on the upper template. The side driving rod 13 is inserted into the core-pulling slider 10 and is slidably matched with the core-pulling slider 10. When the mold is opened, the upward movement of the upper template can drive the side driving rod to move vertically upward, and the vertical upward movement of the side driving rod can drive the core-pulling slider to move away from the forming cavity.

[0031] Specifically, a connecting chute 14 with a T-shaped cross-section is recessed on the core-pulling slider 10. One end of the lower insert 12 away from the forming cavity 2 is fixedly connected with a connecting block 15 with a circular cross-section. The connecting block 15 is inserted into the connecting chute 14 and is slidably matched with the connecting chute 14. The connection of the lower insert 12 to the core-pulling slider through the connecting block and the connecting chute is convenient for assembly and disassembly.

[0032] Specifically, in combination with Figure 1 and Figure 2The shown No. 1 side core-pulling assembly 3 includes a No. 1 side insert block 16 slidably arranged on the lower template 1. The inner end of the No. 1 side insert block 16 is inserted into the molding cavity 2.

The No. 1 driving rod 17 is inserted into the No. 1 side insert block 16 and is slidably matched with the No. 1 side insert block 16. When the mold is opened, the upward movement of the upper template can drive the No. 1 driving rod to move vertically upward, and the vertical upward movement of the No. 1 driving rod can drive the No. 1 side insert block to move away from the molding cavity to realize the automatic core-pulling of the No. 1 side insert block 16.

[0033] Specifically, as shown in Figure 1 the figure, the No. 2 side core-pulling assembly 4 includes a No. 2 side insert block 18 slidably arranged on the lower template 1. The inner end of the No. 2 side insert block 18 is inserted into the molding cavity 2. The No. 2 side core-pulling assembly 4 further includes a No. 2 driving rod 19 obliquely fixed on the upper template. The No. 2 driving rod 19 is inserted into the No. 2 side insert block 18 and is slidably matched with the No. 2 side insert block 18. When the mold is opened, the upward movement of the upper template can drive the No. 2 driving rod to move vertically upward, and the vertical upward movement of the No. 2 driving rod can drive the No. 2 side insert block to move away from the molding cavity to realize the automatic core-pulling of the No. 2 side insert block.

[0034] The working principle of the present utility model is that two molding cavities 2 on the left and right sides of the slope can inject and mold two lamp decoration frame products at one time. The double insert integrated core-pulling assembly 5 can realize the core-pulling of two inserts at one time, which can reduce the number of core-pulling mechanisms on the mold and thus reduce the mold cost. After the product is injection-molded, when the mold is opened, the upward movement of the upper template can realize automatic core-pulling through the No. 1 side core-pulling assembly 3, the No. 2 side core-pulling assembly 4 and the double insert integrated core-pulling assembly 5. The multi-point feeding structure can increase the injection efficiency;

[0035] Through the No. 1 feeding groove 6 and the No. 1 feeding runner 7, the glue can be fed into the molding cavity from the inner side of the molding cavity. Through the No. 2 feeding groove 8 and the No. 2 feeding runner 9, the glue can be fed into the molding cavity from the outer side of the molding cavity. The synchronous feeding of the inner and outer sides of the molding cavity can improve the feeding efficiency. The upper insert 11 and the lower insert are respectively arranged on the upper and lower sides of the core-pulling slider and are arranged in parallel. When the core-pulling slider moves away from the molding cavity, the synchronous core-pulling of the upper insert 11 and the lower insert can be realized. When the mold is opened, the upward movement of the upper template can drive the side driving rod to move vertically upward, and the vertical upward movement of the side driving rod can drive the core-pulling slider to move away from the molding cavity. The lower insert 12 is connected to the core-pulling slider through the connecting block and the connecting chute, which is convenient for assembly and disassembly;

[0036] During mold opening, the upward movement of the upper template can drive the first driving rod to move vertically upward, and the vertical upward movement of the first driving rod can drive the first side insert to move away from the molding cavity to achieve the automatic core pulling of the first side insert 16. During mold opening, the upward movement of the upper template can drive the second driving rod to move vertically upward, and the vertical upward movement of the second driving rod can drive the second side insert to move away from the molding cavity to achieve the automatic core pulling of the second side insert.
