Embodiment 1

[0040] refer to figure 1 and figure 2, a separation box cover injection mold includes a movable mold 1, a fixed mold 2, an ejection mechanism and a slider mechanism, and the necessary structures and systems in the remaining injection molds, because those skilled in the art know, so this patent is no longer repeat. The slider mechanism includes two main sliders 3 that are oppositely arranged and slidably connected to the movable mold 1, and two auxiliary sliders 4 that are slidably connected to the movable mold 1. The sliding direction of the main slider 3 is parallel to the width direction of the movable mold 1 , the auxiliary slider 4 moves on the middle vertical plane in the width direction of the movable mold 1 .

[0041] refer to image 3 and Figure 4 , a first molding cavity 5 is formed between the two opposite main sliders 3 and the movable mold 1, the first molding cavity 5 has a molding position 51 for forming two separate lids, and the two molding positions 51 c...

Embodiment 2

[0052] A kind of separation box cover injection mold, refer to Figure 7 and Figure 8 The difference from Embodiment 1 is that the protruding forming post 141 includes a protruding post 142 integrally formed on the mounting block 15, and a sliding ring 143 that is slidably connected to the end of the protruding post 142 away from the mounting block 15, for forming a part The sub-molding cavity 17 of the connecting pipe 13 is opened at the end of the extending column 142 away from the mounting block 15, and the inner wall of the sub-molding cavity 17 is provided with an outer ring piece 144 that is arc-shaped in section and is used for forming the convex ring 14. The outer ring piece 144 It is ring-shaped, and the outer ring piece 144 is made of a material with deformability, but the deformability is relatively weak; the outer wall of the outer ring piece 144 is fixedly connected with the extension column 142 near the mounting block 15, and a hoop 146 is connected at the other...

Embodiment 3

[0054] A kind of separation lid injection mold, and the difference of embodiment 1 is, with reference to Figure 9 , the adjusting member 23 is a cylinder, and the edge of the adjusting member 23 facing the end face of the positioning column 22 is provided with a protruding point 231 protruding from the end face of the adjusting member 23, and the protruding point 231 is eccentric to the rotation center of the adjusting member 23, protruding The point 231 is in the shape of a cone, the adjusting member 23 is rotatably connected to the positioning plate 10, a linkage rod 26 is fixedly connected to the side wall of the ejector rod 242, and the end of the linkage rod 26 away from the ejector rod 242 is hinged with a linkage slider 261, The linkage slider 261 is fixedly connected with a driving rod 262 to the adjusting member 23, and a groove parallel to the sliding direction of the positioning column 22 is provided on the movable mold 1, and the linkage slider 261 moves in the gro...

Abstract

The separation box cover injection mold comprises a movable mold body, a fixed mold body and an ejection mechanism, the movable mold body is slidably connected with two oppositely-arranged main sliding blocks, the movable mold body is slidably connected with an auxiliary sliding block in the direction perpendicular to the sliding direction of the main sliding blocks, and a first forming cavity is formed between the two main sliding blocks and the movable mold body; the auxiliary sliding block is connected with a communicating cavity forming column which extends into the main sliding block and is used for forming an inner cavity of a communicating pipe, the auxiliary sliding block is connected with an outwards-protruding forming column which extends into the main sliding block, an annular groove used for forming a protruding ring of the communicating pipe is formed in the inner wall of the outwards-protruding forming column, and the communicating cavity forming column penetrates through the outwards-protruding forming column and is slidably connected to the outwards-protruding forming column; the fixed mold is connected with an inclined guide column for driving the auxiliary sliding block to move; and the movable mold is provided with a driving mechanism for driving one of the main sliding blocks to move. The mold has the good effect of forming the communicating pipe and the convex ring.

Description

technical field [0001] The application relates to the field of moulds, in particular to an injection mold for separating lids. Background technique [0002] Injection molds are used to form various product parts. According to the structural shapes of different product parts, different molds will be designed and manufactured for molding. [0003] Conventional molds generally include a movable mold, a fixed mold, a molding cavity between the movable mold and the fixed mold, and according to the structure of different products, different structures of sliders, cooling systems and ejection mechanisms are selectively designed to facilitate the production of products. Better forming and demoulding. [0004] refer to figure 1 One of the separation box covers includes a main cover 11, a round platform 12 integrally formed on the upper end surface of the main cover 11, a connecting tube 13 integrally formed on the side wall of the round platform 12 and connected to the inside of th...
