DETAILED DESCRIPTION

[0026] like Figure 1-Figure 5 As shown, a straight ejector block core pulling mechanism of a car headlight decorative frame mold includes an upper template 1 and a lower template 2. Four molding cavities 3 are arranged between the upper template 1 and the lower template 2. The four molding cavities 3 are symmetrically arranged in pairs. Two lower ejector mechanisms 4 are arranged on the lower side of the lower template 2. Each lower ejector mechanism 4 corresponds to two molding cavities 3. Two side core pulling assemblies 5 are arranged between two molding cavities 3 corresponding to the same lower ejector mechanism 4. Two upper ejector mechanisms 6 corresponding to the two lower ejector mechanisms 4 are also arranged on the upper side of the upper template 1.

[0027] In the utility model, the four molding cavities 3 between the upper template 1 and the lower template 2 can be injection molded four decorative frame products at one time. After the products are injection molded, the upper template moves vertically upward under the drive of the injection molding machine. When the upper template moves upward, the side core pulling assembly 5 can automatically pull the core, and the upper ejection mechanism 6 can remain stationary relative to the upper template so as to resist the product, so that the product cannot adhere to the upper template. When the upper template moves to resist the upper ejection mechanism, it can drive the upper ejection mechanism to move upward and separate from the product, and then the product is ejected from the lower template through the lower ejection mechanism.

[0028] Specifically, the upper ejection mechanism 6 includes an upper ejector plate 7 disposed on the upper side of the upper mold plate 1, with a gap between the upper ejector plate 7 and the upper mold plate 1, and two upper straight ejector assemblies corresponding to the two molding cavities 3 are disposed on the upper ejector plate 7, respectively, and the upper straight ejector assemblies include an upper straight ejector rod 8, an upper straight ejector block 10 connected to the upper ejector plate 7 through an upper vertical ejector rod 9, a No. 1 insert ejector block 11 vertically inserted into the molding cavity 3, and a No. 2 insert ejector block 13 connected to the upper ejector plate 7 through a plurality of upper ejector pins 12. When the mold is opened, the upper mold plate moves vertically upward under the action of the injection molding machine. When the upper mold plate moves upward, the upper ejector plate remains stationary under the action of the injection molding machine so that the upper surface of the product can be pressed against by the upper straight ejector assembly to prevent the product from adhering to the upper mold plate. When the upper mold plate moves to abut against the upper ejector plate, the upper ejector plate can be driven to move upward to separate the upper ejector assembly from the product.

[0029] Specifically, when the mold is opened, the upper straight ejector rod 8, the upper straight ejector block 10, the No. 1 insert ejector block 11 and the No. 2 insert ejector block 13 on the upper ejector plate can resist the upper surface of the product.

[0030] Specifically, the molding cavity 3 is formed by a combination of a top mold 14 and a bottom mold 15 respectively arranged on the upper mold plate 1 and the lower mold plate 2. The top mold 14 is detachably connected to the upper mold plate 1 by a plurality of screws, and the bottom mold 15 is detachably connected to the lower mold plate 2 by a plurality of screws. The detachable connection between the top mold 14 and the upper mold plate can be easily disassembled, and the detachable connection between the bottom mold 15 and the lower mold plate can be easily disassembled, so that the top mold and the bottom mold can be easily replaced when they are damaged without replacing the upper mold plate and the lower mold plate as a whole.

[0031] Specifically, the lower ejection mechanism 4 includes a lower ejector plate 16, on which two lower straight ejector assemblies respectively connected to the two molding cavities 3 are arranged, and the lower straight ejector assemblies include a lower straight ejector rod 17 and a lower straight ejector block 19 connected to the lower ejector plate 16 through a lower vertical ejector rod 18. The vertical upward movement of the lower ejector plate can exert a vertical upward thrust on the product through the lower straight ejector rod, the lower vertical ejector rod 18 and the lower straight ejector block, so that the product can be ejected from the lower template.

[0032] Specifically, the side core pull assembly 5 includes a side core pull seat 20 arranged on the lower mold plate 2, and a side core rod 21 inserted into the side of the molding cavity 3 is arranged on the side core pull seat 20, and an inclined driving rod 22 is fixed on the upper mold plate 1. The upper mold plate moves upward to drive the driving rod to move vertically upward, and the driving rod moves vertically upward to drive the side core pull seat to move away from the molding cavity, and the movement of the side core pull seat can drive the side core rod to move so that the side core rod and the product can be separated.

[0033] Preferably, a connecting slot 23 with a T-shaped cross section is provided on the side core pull seat 20, the cross section of the outer end of the side core rod 21 is T-shaped and inserted into the connecting slot 23, and the upper and lower ends of the connecting slot 23 are penetrated. The connecting slot with a T-shaped cross section on the side core pull seat 20 makes the side core rod 21 and the side core pull seat slide in a sliding fit, and the side core rod and the side core pull seat can be separated by sliding the side core rod up and down.

[0034] The working principle of the utility model is as follows: the four molding cavities 3 between the upper template 1 and the lower template 2 can be used for injection molding four decorative frame products at one time. After the products are injection molded, the upper template moves vertically upward under the drive of the injection molding machine. When the upper template moves upward, the side core pulling assembly 5 can automatically pull the core, and the upper ejection mechanism 6 can remain stationary relative to the upper template so as to resist the product, so that the product cannot adhere to the upper template. When the upper template moves to resist the upper ejection mechanism, it can drive the upper ejection mechanism to move upward and separate from the product, and then the product is ejected from the lower template by the lower ejection mechanism.

[0035] When the mold is opened, the upper template moves vertically upward under the action of the injection molding machine. When the upper template moves upward, the upper top plate remains stationary under the action of the injection molding machine so that the upper straight top assembly can be used to press against the upper surface of the product to prevent the product from adhering to the upper template. When the upper template moves to press against the upper top plate, it can drive the upper top plate to move upward to separate the upper ejection assembly from the product. When the mold is opened, the upper straight ejector rod 8, the upper straight ejector block 10, the No. 1 insert ejector block 11 and the No. 2 insert ejector block 13 on the upper top plate can press against the upper surface of the product. The top mold 14 and the upper template are detachably connected to facilitate disassembly, and the bottom mold 15 and the lower template are detachably connected to facilitate disassembly, so that the top mold and the bottom mold can be easily replaced when they are damaged without replacing the upper mold and the lower mold as a whole.

[0036] The vertical upward movement of the lower ejector plate can exert a vertical upward thrust on the product through the lower straight ejector rod, the lower vertical ejector rod 18 and the lower straight ejector block, thereby ejecting the product from the lower template; the upward movement of the upper template can drive the driving rod to move vertically upward; the vertical upward movement of the driving rod can drive the side core pulling seat to move away from the molding cavity; the movement of the side core pulling seat can drive the side core rod to move, thereby separating the side core rod from the product; the T-shaped connecting groove on the cross-section of the side core pulling seat 20 enables the side core rod 21 to slide with the side core pulling seat, and the side core rod and the side core pulling seat can be separated by sliding the side core rod up and down.
