Description

Technical Field

[0001] This utility model relates to the technical field of circular lamp bodies, and in particular to a die-casting mold core structure for waterproof and explosion-proof circular lamp bodies. Background Technology

[0002] During the production of waterproof and explosion-proof lamp bodies, it is necessary to ensure that the product has a certain structural strength. Conventional die-casting molds usually place the gate structure at one end of the mold cavity structure. This results in a very large flow distance of molten aluminum during the product molding process, so a very large hydraulic pressure is required to fill the entire mold cavity with molten aluminum. This production method will cause some molten aluminum residue to appear at the edges of the product. To solve this problem, the mold needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a die-casting mold core structure for waterproof and explosion-proof circular lamp bodies, which has the characteristics of reducing the flow distance of aluminum liquid, increasing the filling speed of aluminum liquid, reducing the filling pressure required for the product and improving product quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a die-casting mold core structure for waterproof and explosion-proof circular lamp bodies is provided, including an upper mold core, a lower mold core and a gate structure. The upper mold core and the lower mold core are stacked vertically, forming a mold cavity between them. A gate structure is provided in the middle of the upper end face of the upper mold core. A forming boss is provided in the middle of the upper end face of the lower mold core. A planar structure is provided at the upper end of the forming boss. A downwardly curved arc side is provided on the outer ring of the forming boss. A flow divider cone structure that connects with the lower end of the gate structure is embedded in the middle of the upper end face of the forming boss. Two main channels are symmetrically arranged on the planar structure. The main channels are arc-shaped and arranged along the edge of the planar structure. Several injection nodes are provided on the main channels.

[0005] In this technical solution, a forming boss is set to facilitate the forming of the inner side of the product. At the same time, a flow divider cone structure is set in the middle of the upper end face of the forming boss to shorten the flow distance of the aluminum liquid and improve the filling efficiency of the aluminum liquid. An arc-shaped side is set to facilitate the outward flow of the aluminum liquid and further improve the filling efficiency of the aluminum liquid. Meanwhile, the main channel and injection node are set to facilitate the rapid filling of the mold cavity.

[0006] As a supplement to this technical solution, a number of reinforcing rib forming grooves are evenly provided on the arc-shaped side surface, and the reinforcing rib forming grooves are provided with ejector pin openings. The reinforcing rib forming grooves are provided to facilitate the forming of internal reinforcing ribs of the product, and the ejector pin openings are provided to facilitate ejector pin replenishment.

[0007] As a supplement to this technical solution, a ring of upward-protruding parting ribs is provided at the edge of the lower mold core, and an embedding groove matching the parting ribs is provided at the lower end face edge of the upper mold core. The parting ribs and embedding grooves are used to improve the sealing degree of the mold.

[0008] As a supplement to this technical solution, four sets of venting block assemblies are symmetrically arranged at the front and rear positions of the upper mold core and the lower mold core.

[0009] As a supplement to this technical solution, a number of venting slag packs are provided on the upper surface of the lower mold core. The venting slag packs are arranged around the forming boss and are divided into four groups. The four groups of venting slag packs are respectively connected to four groups of venting block assemblies through shallow venting grooves.

[0010] Beneficial effects: This utility model relates to a die-casting mold core structure for waterproof and explosion-proof circular lamp bodies. By setting a forming boss, the inner side of the product can be easily formed. At the same time, by setting a flow-diverting cone structure in the middle of the upper end face of the forming boss, the flow distance of the molten aluminum can be shortened, thereby improving the filling efficiency of the molten aluminum. By setting an arc-shaped side, the molten aluminum can flow outward, further improving the filling efficiency of the molten aluminum. At the same time, by setting a main channel and injection node, the mold cavity can be quickly filled. It has the characteristics of reducing the flow distance of the molten aluminum, increasing the filling speed of the molten aluminum, reducing the filling pressure required for the product and improving the product quality.
