Problems solved by technology
There are two disadvantages: first, if the standard of engraving first and the standard of drilling machine processing are inconsistent, deviations will easily occur, resulting in eccentric screw holes, and the assembly screw holes will be cracked by screws during production and assembly; During the drilling process, if the drill bit is installed off-position, the hole diameter of the drilling process is larger than the outer diameter of the push tube, resulting in flashing at the mouth of the assembly screw during injection molding.
The above defects will make it difficult to assemble such products during assembly, waste manpower and working hours, and increase product costs

Embodiment Construction
[0012] Such as figure 1 , figure 2 As shown, the push tube insert structure of the resin lens injection mold of the present invention is composed of a movable mold frame, a push tube insert 1 , a hexagon socket set screw 2 and a copper block 3 .
[0013] In the structure of the present invention, the push tube insert is the key point, and the fixed screw column of the push tube on the movable mold frame is used as an inlaid structure. The matching part of the push tube 4 is designed on the push tube insert 1, and the movable mold frame is pushed Tube 4 avoids the void, that is, the push tube 4 has no contact with the movable mold frame, and the push tube 4 is only matched with the push tube hole on the push tube insert 1. 2. The inner hexagonal fixing screw 2 passes through the counterbore to fix the push tube insert 1 on the movable mold frame. The counterbore is provided with steps for the copper block 3 to be embedded and sealed in the counterbore. The copper block 3 The...

The invention discloses a pushing pipe inert block structure for a resin lens injection mould. The pushing pipe inert block structure for the resin lens injection mould consists of a pushing pipe inert block (1), a hexagonal socket fixing screw (2) and a copper plug block (3), and is characterized in that a counter bore is formed in the pushing pipe inert block (1); when the hexagonal socket fixing screw (2) passes through the counter bore, the pushing pipe inert block (1) is fixed to a moving mould frame; a step is arranged in the counter bore, and the copper plug block (3) seals the counter bore. According to the pushing pipe inert block structure for the resin lens injection mould, the problem of burrs of a fixing screw and stud and the problem of eccentricity of a fixing screw hole of the injection mould when the resin lens injection mould is assembled can be solved; later-period completion and maintenance of the mould are facilitated.
Description
technical field [0001] The invention relates to the technical field of resin lens injection molds, in particular to a push tube insert structure. [0002] technical background [0003] Since the resin lens injection mold is assembled with reinforcing ribs around the screw holes on the mold, it is more laborious to eject the product after injection molding. If the mold is not properly handled here, the product will appear white and reinforced. Fracture, screw column deformation and other poor molding phenomena, so in order to ensure smooth product ejection, the general assembly screw hole is designed as a push tube structure on the mold structure. The traditional assembly screw hole push tube processing process mainly adopts the following two methods: 1) First Drilling machine to process the push tube hole, and then finely engraving and machining the front forming part of the assembly screw hole; 2) First CNC finely engraving and machining the front forming part of the assembl...
