Embodiment 1

[0024] like figure 1 , figure 2 , image 3 , Figure 5 In the embodiment shown, an automatic insert injection mold includes an upper mold 1, a lower mold 2, a cylinder 3, and a blanking mechanism. The blanking mechanism includes a blanking pipe 4 connected to a vibration plate. The lower end of the feeding tube 4 is provided with a feeding push block 5 with a feeding hole, and the feeding push block 5 is located in a push block groove slidingly connected with the feeding push block 5. There is a push plate 6, the front of the push plate 6 is in contact with the upper die block 7 in the upper die 1, the back of the push plate 6 is provided with a spring 8, and the spring 8 is in a compressed state when the mold is closed, and the described push plate 6 is in a pressed state. The feeding mechanism also includes a feeding push rod 9 driven by the air cylinder 3. The lower end of the feeding push rod 9 is facing one end of the material holding hole, and the pre-embedded positi...

Embodiment 2

[0027] In this embodiment, the basic structure and implementation are the same as those in Embodiment 1, and the differences are as follows: Figure 4 , Image 6 , Figure 7 Shown in: the feed pipe 4 is provided with an air intake push structure, and the air intake push structure includes a main air pipe 14, the main air pipe 14 is connected to a number of inclined air pipes 15, the inclined air pipe 15 and the feed pipe 4 is connected, and the communication position between the inclined gas pipe 15 and the feeding pipe 4 is located at the lower part of the inclined gas pipe 15 and above the pre-embedded position. The main air pipe 14 is used to connect the air supply device such as an air pump. When feeding, the air supply device supplies air, and the air is blown into and pressed into the lower part of the feeding pipe 4 through the inclined air pipe 15 to push the ceramic insert 17 . The assembly and connection accuracy of the ceramic ferrule 17 is relatively high. In ord...

Abstract

The invention discloses an automatic member-embedding injection mould. The automatic member-embedding injection mould has the advantages of automatic blanking, accurate positioning, high cooperation precision, and continuous and high efficiency injection moulding process. The automatic member-embedding injection mould comprises an upper die, a lower die, a cylinder and a blanking mechanism; the blanking mechanism comprises a blanking tube, a feeding push block with an accommodation hole is arranged at the lower part of the blanking tube, the feeding push block is positioned in a block pushing groove connected to the feeding push block in a slide mode, a compression extrusion plate is arranged besides the feeding push block, the right side of the compression extrusion plate is contacted to an upper die briquetting in the upper die, a spring is provided at the back of the compression extrusion plate, the spring is in a compaction state while the mould is closed, the blanking mechanism also comprises a feeding push rod driven by the cylinder, the lower end of the feeding push rod just faces to one end of the accommodation hole, a pre-embedding position in the mould cavity is positioned at the lower part of the accommodation hole, and a discharging push rod is provided on the lower die. The automatic member-embedding injection mould has the advantages of automatic feeding and blanking, rapid blanking in place and accurate positioning, the stability is high while injection moulding, and the cooperation precision of the molded product is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mold forming, and in particular relates to an automatic insert injection mold. Background technique [0002] Optical fiber quick connector is one of the key components in the field of optical fiber to the home. Among the current optical fiber quick connectors, one is more commonly used, which is composed of a ceramic ferrule insert and a flange core base plastic part. The ceramic ferrule insert is provided with an optical fiber hole. In some cases, the hole diameter is very small or the precision is very high. In the case of , one end of the ceramic ferrule is also provided with a chamfered groove to facilitate the entry of the optical fiber. There are roughly two ways to form the quick connector, one is to glue the ceramic ferrule and the plastic part of the flange core with glue, and the other is to directly inject the ceramic and plastic parts. Although both can realize the combination of product man...
