Description

Technical Field

[0001] This utility model relates to the field of wall lamp housing manufacturing technology, and in particular to a die-casting mold structure for wall lamp housings. Background Technology

[0002] The wall lamp housing's docking seat uses an inclined structure. Inclined structures typically employ an inclined core-pulling design. However, when the inclined hydraulic cylinder directly pulls out the core, it can damage the product. To solve this problem, a transitional core-pulling structure needs to be designed. This transitional core-pulling will extend the overall length of the core-pulling structure. Therefore, the transitional core-pulling needs to be modified to shorten the core-pulling stroke while avoiding direct demolding by the hydraulic cylinder, thereby reducing the overall cost of the mold and minimizing its size. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a die-casting mold structure for wall lamp housings, which has the characteristics of reducing mold cost, reducing mold volume, and facilitating oblique core pulling and demolding.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A die-casting mold structure for wall lamp housings is provided, including an upper mold, a lower mold, a left core-pulling structure, a right detachable core-pulling structure, and a demolding core-pulling structure. The upper and lower molds are stacked vertically. A mold foot structure is installed on the lower end face of the lower mold. An upper mold core and a lower mold core are installed between the upper and lower molds. A mold cavity structure is installed between the upper mold core and the lower mold core. A left core-pulling structure for inserting into the mold cavity structure is installed on the left side of the upper mold. A right detachable core-pulling structure is installed on the right side of the upper mold. A demolding core-pulling structure is installed on the right side of the lower mold. The core-pulling structure includes a right core-pulling slider, a right core-pulling bracket, and a right core-pulling cylinder. The right core-pulling slider is installed inside the right end of the upper mold. The left side of the right core-pulling slider is provided with a bottom-inclined right-facing inclined slider. A core-pulling slider is installed on the bottom-inclined slider. The side of the core-pulling slider near the mold cavity structure is provided with a right-end-inclined inclined core-pulling mechanism. The right side of the upper mold is provided with a right core-pulling bracket. The right core-pulling bracket is provided with a right core-pulling cylinder. A track through hole is provided on the right side of the core-pulling slider. The main shaft of the right core-pulling cylinder extends into the track through hole. The main shaft of the demolding core-pulling structure faces upward towards the lower side of the core-pulling slider.

[0005] In this technical solution, a right core-pulling slider is installed to drive the core-pulling slider to perform the demolding action. The demolding structure is controlled by the docking inclined slider of the core-pulling slider and the matching groove located at the left end of the right core-pulling slider. When the right core-pulling slider moves upward, the right core-pulling slider drives the core-pulling slider to tilt and pull out through the docking inclined slider, so that the core-pulling slider can tilt and pull the inclined core out of the mold cavity to achieve demolding. Then, the right core-pulling cylinder completely pulls out the right core-pulling slider, the core-pulling slider, and the inclined core. This operation method can avoid product damage while also ensuring a shorter overall stroke of the right disengagement core-pulling structure, reducing the overall cost of the mold, and reducing the overall size of the mold.

[0006] Meanwhile, the track through-hole is used to ensure that the core-pulling slider can move upwards.

[0007] As a supplement to this technical solution, the demolding and core-pulling structure includes a demolding cylinder, a sleeve mounting plate, and a pipe. The sleeve mounting plate is horizontally installed on the right side of the upper mold and is located below the right core-pulling slider. A pipe passing through the upper mold is installed on the sleeve mounting plate. A demolding cylinder corresponding to the main shaft and the pipe is installed on the right side of the lower mold.

[0008] In this technical solution, the demolding cylinder is used to facilitate the pushing of the core-pulling slider. The installation of the pipe sleeve mounting plate facilitates the installation of the pipe, and the installation of the pipe facilitates the extension of the main shaft of the demolding cylinder.

[0009] As a supplement to this technical solution, a gate structure is installed at the rear of the upper mold.

[0010] As a supplement to this technical solution, the left core-pulling structure includes a left support, a left hydraulic cylinder, a left core-pulling slider, and a left core. The left support is installed on the left side of the upper mold, and a left hydraulic cylinder with its main shaft facing right is installed on the left support. A left core-pulling slider that connects with the left hydraulic cylinder is installed on the left side of the upper mold, and a left core-pulling structure that inserts into the mold cavity is installed on the right side of the left core-pulling slider.

[0011] Beneficial Effects: This utility model relates to a die-casting mold structure for wall lamp housings. A right-side core-pulling slider is installed to drive the core-pulling slider in a demolding action. The demolding process is controlled by the connecting inclined slider and the matching groove located at the left end of the right core-pulling slider. When the right core-pulling slider moves upward, it tilts and pulls out through the connecting inclined slider, allowing the inclined core to be pulled out of the mold cavity, thus achieving demolding. Then, a right core-pulling cylinder completely pulls out the right core-pulling slider, the core-pulling slider, and the inclined core. This operation method avoids product damage while shortening the overall stroke of the right-side core-pulling structure, reducing the overall cost of the mold, and shrinking the overall size of the mold. It features reduced mold cost, smaller mold size, and convenient inclined core demolding. Attached Figure Description
