Problems solved by technology

Therefore, during die-casting production, the following phenomena will occur: 1. The top column of the product shape is often short of material, and it is difficult to control when it is high and low, and it is difficult to polish or the top is missing, resulting in product scrap; The column is often stuck and cannot be produced normally; 3. Due to the assembly relationship on the left side of the sealing groove, the two top columns on the left side of the sealing groove must be processed, and the machining allowance is large, resulting in low production efficiency; 4. The two top pillars on the left side of the sealing groove need to be processed to remove the excess, resulting in an extra consumption of about 20g for each piece of aluminum alloy material

Embodiment Construction

[0011] Such as figure 1 , 2 As shown: the lower template of the LED lampshade mold, including a rectangular die-casting mold 1 arranged horizontally, a sealing groove 2, and a top pillar 3 arranged around the sealing groove 2, and the top pillar 3 arranged around the sealing groove 2 has a cylindrical structure. A connecting rod 4 is provided between the top post 3 and the sealing groove 2, the length of the connecting rod 4 is 1-3 mm, and the connecting rod 4 and the top post 3 are integral structures.

[0012] In the present invention, the structure of the top pillar 3 which is arranged close to the periphery of the sealing groove 2 is changed from a circular arc shape to a cylindrical shape, and the distance between the top pillar 3 and the sealing groove 2 is increased. During die-casting and secondary processing, The phenomenon of interference between the top post 3 and the sealing groove 2 is prevented. For example: to avoid the lack of material in the top column of th...

Abstract

The invention belongs to the technical field of light-emitting diode (LED) illumination equipment, and in particular relates to a novel lower die plate of an LED lamp shade die. The novel lower die plate of the LED lamp shade die comprises a transversely arranged rectangular pressure casting die, a sealing groove and cylindrical top pillars tightly attached to the periphery of the sealing groove. The top pillars tightly attached to the periphery of the sealing groove are cylindrical instead of arc, so that the distances between the top pillars and the sealing groove are increased, the phenomenon of interference between the top pillars and the sealing groove is avoided during pressure casting and secondary processing, and a lamp shade is convenient to produce and process.

Description

technical field [0001] The invention belongs to the technical field of LED lighting equipment, and in particular relates to a lower template of an LED lampshade mold. Background technique [0002] At present, in the LED lampshade molds on the market, the convex groove for placing the LED lamp on the lower template is set on the top of the lower template. Therefore, the distance between the top column and the sealing groove is very small, and there will be interference during production and processing. Therefore, during die-casting production, the following phenomena will occur: 1. The top column of the product shape is often short of material, and it is difficult to control when it is high and low, and it is difficult to polish or the top is missing, resulting in product scrapping; 2. The top column that fits the sealing groove The column is often stuck and cannot be produced normally; 3. Due to the assembly relationship on the left side of the sealing groove, the two top c...
