Abstract
The invention belongs to LED illumination device technical field, especially relate to a kind of LED lamp cover lower mould plate.This LED lamp cover lower mould plate includes the rectangle die casting of horizontally set, seal groove, be close to seal groove surrounding arrange fore-set, described in be close to seal groove surrounding arrange withstanding structure for cylinder.So change, from circular arc, the roof pillar configuration being originally close to the setting of seal groove surrounding into cylinder, increase the distance between fore-set and seal groove, when die casting, secondary operations, prevent from interfering between fore-set and seal groove phenomenon, facilitate the production of lampshade, processing.
Description
Technical field
The invention belongs to LED illumination device technical field, especially relate to a kind of LED lamp cover lower mould plate.
Background technology
At present, in LED lamp cover mould on market, the tongue of lower bolster placement LED lamp is arranged on the top of lower bolster, this lampshade structure is in press casting procedure, owing to the fore-set on lower bolster is circular arc, and arrange with seal groove laminating, so the distance between fore-set and seal groove is the least, in production, the course of processing, have interference.So when Die Casting, it may appear that following phenomenon: 1, often make the fore-set of product design lack material, time height time low wayward, polishing difficulty or act during a vacancy and cause product rejection；2, the fore-set that gluing, sealing groove is arranged is the most stuck, it is impossible to normally produce；3, there is assembly relation due to the left side of seal groove, cause on the left of gluing, sealing groove two fore-sets to process, and allowance is very big, causes production efficiency low；4, two fore-sets on the left of gluing, sealing groove need to machine away many surpluses, cause aluminum alloy materials every to consume about 20g more.
Summary of the invention
The present invention can provide one can conveniently produce, process, and improves the LED lamp cover lower mould plate of production efficiency.
In order to solve above-mentioned technical problem, LED lamp cover lower mould plate, including rectangle die casting, the seal groove of horizontally set, be close to the fore-set that seal groove surrounding is arranged, described in be close to the roof pillar configuration that seal groove surrounding arranges be cylinder.
Use above-mentioned technical scheme, in the present invention, change, from circular arc, the roof pillar configuration being originally close to the setting of seal groove surrounding into cylinder, increase the distance between fore-set and seal groove, when die casting, secondary operations, prevent from interfering between fore-set and seal groove phenomenon.Such as: avoid making the fore-set of product design to lack material, time height time low wayward, polishing difficulty or act during a vacancy and cause product rejection, improve the qualification rate of product；The fore-set avoiding gluing, sealing groove to arrange is the most stuck, it is impossible to normally produce；Simultaneously because there is assembly relation in the left side of seal groove, so two fore-sets on the left of gluing, sealing groove must be processed, but original fore-set and seal groove are same die casting chamber, so original fore-set height value is big, need the cutting output that machines away big, cause that production efficiency is low, waste aluminum alloy materials.Fore-set in this patent, when die casting, can reduce the height of fore-set, thus reduce cutting output, improves production efficiency, has saved aluminum alloy materials.
Further, because fore-set is cylindrical structural, so being directly connected to destroy the surface texture of fore-set between fore-set and seal groove, affect the dimensional accuracy of postorder processing, it is provided with connecting rod between place fore-set and seal groove, the length of connecting rod is set to 1～3mm, meet our processing dimension requirement.
Further, described connecting rod and fore-set are monolithic construction, facilitate die casting and Stability Analysis of Structures.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of LED lamp cover lower mould plate of the present invention；
Fig. 2 is the structural representation of LED lamp cover lower mould plate fore-set of the present invention.
Detailed description of the invention
As shown in Figure 1, 2: LED lamp cover lower mould plate, rectangle die casting 1, seal groove 2 including horizontally set, it is close to the fore-set 3 that seal groove 2 surrounding is arranged, fore-set 3 structure being close to the setting of seal groove 2 surrounding is cylinder, it is provided with connecting rod 4 between described fore-set 3 and seal groove 2, a length of the 1 of connecting rod 4～3mm, connecting rod 4 and fore-set 3 are monolithic construction.
In the present invention, change, from circular arc, fore-set 3 structure being originally close to the setting of seal groove 2 surrounding into cylinder, increase the distance between fore-set 3 and seal groove 2, when die casting, secondary operations, prevent from interfering phenomenon between fore-set 3 and seal groove 2.Such as: avoid making the fore-set of product design to lack material, time height time low wayward, polishing difficulty or act during a vacancy and cause product rejection, improve the qualification rate of product；The fore-set 3 avoiding gluing, sealing groove 2 to arrange is the most stuck, it is impossible to normally produce；Simultaneously because there is assembly relation in the left side of seal groove 2, so two fore-sets 3 on the left of gluing, sealing groove 2 must be processed, but fore-set originally 3 and seal groove 2 are same die casting chamber, so original fore-set 3 height value is big, need the cutting output machined away big, cause production efficiency low, waste aluminum alloy materials, fore-set 3 in this patent is when die casting, the height of fore-set 3 can be reduced, thus reduce cutting output, improve production efficiency, saved aluminum alloy materials, about can save the aluminum alloy materials of 20g by adding up each fore-set 3.Additionally because fore-set 3 is cylindrical structural, so being directly connected to destroy the surface texture of fore-set between fore-set 3 and seal groove 2, affect the dimensional accuracy of postorder processing, connecting rod 4 it is provided with between place fore-set 3 and seal groove 2, the length of connecting rod 4 is set to 1～3mm, meet our processing dimension requirement, when die casting, connecting rod 4 and fore-set 3 are cast into monolithic construction, Stability Analysis of Structures simultaneously.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; on the premise of without departing from present configuration; some deformation and improvement can also be made; also should be considered as protection scope of the present invention, these are all without affecting effect and the practical applicability that the present invention implements.
Claims (2)
1. Novel LED lampshade lower mould plate, including rectangle die casting, the seal groove of horizontally set, is close to the fore-set that seal groove surrounding is arranged, it is characterised in that: the roof pillar configuration being close to the setting of seal groove surrounding is cylinder, and the fore-set on the left of gluing, sealing groove is two；Connecting rod it is provided with, a length of the 1 of connecting rod～3mm between described fore-set and seal groove.
