[0008] In the above-mentioned synchronous sliding ejection demolding mold for thick-walled light-guiding structural parts, the No. 1 synchronous sliding core-pulling assembly also includes a No. 1 driving rod fixed on the upper template, and the No. 1 driving rod is tilted and inserted into the No. 1 core-pulling slider.

[0009] In the above-mentioned synchronous sliding ejection demolding mold for thick-walled light-guiding structural parts, the No. 2 synchronous sliding core-pulling assembly includes a No. 2 core-pulling slider that is obliquely slidably arranged on the lower template, and the inner end of the No. 2 core-pulling slider is connected to the molding cavity and is provided with a number of core rods inserted into the molding cavity.

The bottom of the upper template is fixedly connected with an inclined No. 2 driving rod, and the No. 2 driving rod is inserted into the core-pulling seat and slides with the core-pulling seat.

[0011] In the above-mentioned thick-walled light-guiding structural component synchronous sliding ejection demolding mold, the inclined guide structure includes an inclined guide groove obliquely arranged at the outer end of the No. 2 core-pulling slider and an inclined guide slider obliquely arranged on the core-pulling seat, and the inclined guide slider is inserted into the inclined guide groove.

[0012] In the above-mentioned die for synchronous sliding ejection of thick-walled light guide structural parts, the cross-sections of the oblique guide sliding blocks and the oblique guide sliding grooves are T-shaped.

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 5As shown, a synchronous sliding ejection demolding mold for thick-walled light-guiding structural parts includes an upper template 1 and a lower template 2. Two molding cavities 3 are symmetrically arranged between the upper template 1 and the lower template 2. Two No. 1 synchronous sliding core-pulling components 4 are respectively connected to the outer sides of the two molding cavities 3 on both sides of the lower template 2. Two No. 2 synchronous sliding core-pulling components 5 are also provided on the lower template 2, which are respectively connected to the inner ends of the two molding cavities 3. The two No. 1 synchronous sliding core-pulling components 4 are oppositely arranged, and the two No. 2 synchronous sliding core-pulling components 5 are arranged in parallel.

[0028] In the present invention, the No. 1 synchronous sliding core pulling component 4 on the outside of the two molding cavities 3 and the No. 2 synchronous sliding core pulling component 5 on the inner ends of the two molding cavities can realize synchronous sliding and core pulling when the mold is opened. Compared with the core pulling component powered by the cylinder, this structure can improve the synchronization between the core pulling components.

[0029] Specifically, combined Figure 2-Figure 5 As shown, the No. 1 synchronous sliding core-pulling assembly 4 includes a No. 1 core-pulling slider 6 horizontally slidably arranged on the lower template 2, the inner end of the No. 1 core-pulling slider 6 is connected to the outer side of the molding cavity 3 and the inner end of the No. 1 core-pulling slider 6 has a side light guide molding surface 7, the No. 1 synchronous sliding core-pulling assembly 4 also includes a No. 1 driving rod 8 fixed to the upper template 1, the No. 1 driving rod 8 is tilted and inserted into the No. 1 core-pulling slider 6. When the mold is opened, the upward movement of the upper template can synchronously drive the No. 1 driving rods corresponding to the two molding cavities to move vertically upward. The vertical upward movement of the two No. 1 driving rods can drive the No. 1 core-pulling sliders in the two No. 1 synchronous sliding core-pulling assemblies 4 to move synchronously outward, thereby realizing the synchronous sliding and core pulling of the two No. 1 core-pulling sliders.

[0030] Specifically, the No. 2 synchronous sliding core-pulling assembly 5 includes a No. 2 core-pulling slider 9 that is obliquely slidably arranged on the lower template 2. The inner end of the No. 2 core-pulling slider 9 is connected to the molding cavity 3 and the inner end is provided with a number of core rods 10 inserted into the molding cavity 3. The No. 2 synchronous sliding core-pulling assembly 5 also includes a core-pulling seat 11 horizontally arranged on the lower template 2. An oblique guide structure is provided between the core-pulling seat 11 and the No. 2 core-pulling slider 9. The bottom of the upper template 1 is fixedly connected with a No. 2 driving rod 12 that is obliquely arranged. The No. 2 driving rod 12 is inserted into the core-pulling seat 11 and slides with the core-pulling seat 11. When the mold is opened, the upward movement of the upper mold plate can synchronously drive the No. 2 drive rods corresponding to the two molding cavities to move vertically upward. The vertical upward movement of the two No. 2 drive rods can drive the two No. 2 synchronous sliding core-pulling seats 11 in the core-pulling assembly 5 to slide horizontally outward. The horizontal outward sliding of the two core-pulling seats can drive the two No. 2 core-pulling sliders 9 to move synchronously obliquely downward through the oblique guide structure, thereby realizing the synchronous sliding and core pulling of the two No. 2 core-pulling sliders and the core rod.

[0031] Specifically, the oblique guide structure includes an oblique guide slot 13 obliquely disposed at the outer end of the second core-pulling slider 9 and an oblique guide slider 14 obliquely disposed on the core-pulling seat 11. The oblique guide slider 14 is inserted into the oblique guide slot 13, and the cross-section of the oblique guide slider 14 and the oblique guide slot 13 is T-shaped. When the core-pulling seat moves horizontally outward, the oblique guide slider 14 and the oblique guide slot 13 cooperate to drive the second core-pulling slider to move obliquely downward, thereby enabling the second core-pulling slider and the core rod to slide back and pull the core.

[0032] Preferably, a gas-top demoulding structure is further provided in the No. 2 core-pulling slider 9, and the gas-top demoulding structure includes a gas-top cavity 15 provided in the No. 2 core-pulling slider 9, and a gas-top block 16 for fixing the core rod 10 is provided in the gas-top cavity 15. The bottom of the No. 2 core-pulling slider 9 is connected to a plurality of high-pressure air pipes 17 respectively connected to the front and rear sides of the gas-top block 16, and the bottom of the high-pressure air pipe 17 is connected to the joint seat 19 through a hose 18. Before opening the mold, high-pressure gas is introduced into the gas-top cavity through the joint seat, the hose and the high-pressure air pipe to drive the gas-top block to move away from the molding cavity so that the core rods connected to the gas-top block can be separated from the molding cavity in advance. Subsequently, when opening the mold, the No. 2 core-pulling slider moves obliquely downward to separate the No. 2 core-pulling slider and the core rod from the product. The use of a secondary core-pulling method can prevent the product from being damaged during core pulling.

[0033] Preferably, the oblique guide slider 14 is detachably fixed to the core-pulling seat 11 by a plurality of screws.

[0034] The working principle of the utility model is as follows: the first synchronous sliding core pulling assembly 4 outside the two molding cavities 3 and the second synchronous sliding core pulling assembly 5 at the inner ends of the two molding cavities can realize synchronous sliding and core pulling when the mold is opened. Compared with the core pulling assembly powered by the oil cylinder, this structure can improve the synchronization between the core pulling assemblies;

[0035] When the mold is opened, the upper template moves upward and can synchronously drive the No. 1 driving rods corresponding to the two molding cavities to move vertically upward. The vertical upward movement of the two No. 1 driving rods can drive the No. 1 core-pulling sliders in the two No. 1 synchronous sliding core-pulling assemblies 4 to move synchronously outward, thereby realizing the synchronous sliding and core-pulling of the two No. 1 core-pulling sliders. When the mold is opened, the upper template moves upward and can synchronously drive the No. 2 driving rods corresponding to the two molding cavities to move vertically upward. The vertical upward movement of the two No. 2 driving rods can drive the core-pulling seats 11 in the two No. 2 synchronous sliding core-pulling assemblies 5 to slide horizontally outward. The two core-pulling seats slide horizontally outward and can drive the two No. 2 core-pulling sliders 9 to move synchronously obliquely downward through the oblique guide structure, thereby realizing the synchronous sliding and core-pulling of the two No. 2 core-pulling sliders and the core rod. The horizontal outward movement of the core-pulling seat can drive the No. 2 core-pulling slider to move obliquely downward through the cooperation of the oblique guide slider 14 and the oblique guide slot 13, thereby realizing the sliding and core-pulling of the No. 2 core-pulling slider and the core rod;

[0036] Before opening the mold, high-pressure gas is introduced into the gas top cavity through the joint seat, hose and high-pressure air pipe to drive the gas top block to move away from the molding cavity, so that several core rods connected to the gas top block can be separated from the molding cavity in advance. Then, when the mold is opened, the No. 2 core-pulling slider moves obliquely downward to separate the No. 2 core-pulling slider and core rod from the product. The use of secondary core pulling can prevent the product from being damaged during core pulling.
