Problems solved by technology

In the production process of existing injection molds, it is often necessary to move the movable mold towards the fixed mold driven by the injection molding equipment, so that the injection molding machine can be formed; in order to ensure good positional stability between the fixed mold and the movable mold , so it is necessary to set up a guiding system to assist in guiding processing; however, the existing guiding systems often use linear moving parts for guiding processing, which has insufficient guiding accuracy

Embodiment 1

[0016] Such as figure 1 A guide system for an injection mold that adopts a rotating guide structure is shown, and the injection mold includes a fixed mold 1 and a movable mold 2; The plurality of guide groove bodies 3 and the plurality of guide end bodies 4 on the movable mold 2 correspond to each other one by one; the inner wall of the guide groove body 3 is provided with There is a first connecting thread 5, the side end surface of the guide end body 4 is provided with a plurality of connecting grooves 6 adopting an annular structure, a guide sleeve 7 is arranged outside the guide end body 4, and a guide sleeve 7 is arranged on the inner wall of the guide sleeve 7 There are a plurality of connection end bodies 8 adopting an annular structure, and the plurality of connection end bodies 8 correspond to the plurality of connection groove bodies 6 one by one, and each connection end body 8 extends into the corresponding connection groove body 6; A second connecting thread 9 is ...

Embodiment 2

[0021] As an improvement of the present invention, such as figure 1 and figure 2 As shown, a lubricating groove body 10 is provided between the thread bottom and the thread crest of the second connecting thread 9, and the lubricating groove body 10 extends along the thread direction of the second connecting thread 9; the first connecting thread 5 The inside is filled with lubricating grease, and the end of the guide groove body 3 is provided with a blocking end body 11 , and when the first connecting thread 5 and the second connecting thread 9 engage with each other, the blocking end body 11 extends into the inside of the lubricating groove body 10 . Adopting the above-mentioned technical scheme, it can make the lubricating oil of the first connecting thread pass through the lubricating groove to move inside the second connecting thread through the setting of the lubricating groove, so that the connection between the first connecting thread and the second connecting thread I...

Embodiment 3

[0024] As an improvement of the present invention, among the second connecting thread 9 , between the crest of the thread and the lubricating groove body 10 and between the bottom of the thread and the lubricating groove body 10 are respectively provided with a support end body 901 adopting a curved surface structure. . Using the above technical solution, it can make the second connection thread contact with the first connection thread through the support end body through the setting of the support end body, and then reduce the contact area of ​​the second connection thread with respect to the first connection thread to The friction between them can be reduced, resulting in improved overall connection efficiency.

[0025] The remaining features and advantages of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses a guide system for an injection mold. By means of the guide system for the injection mold, a rotary guide structure is adopted, the injection mold includes a fixed mold and a movable mold, the guide system used for the injection mold and using the rotary guide structure includes a plurality of guide groove bodies and a plurality of guide end bodies which are correspondinglyarranged on the fixed mold and the movable mold correspondingly; a first connection thread is arranged on the inner wall of each guide groove body; the side end surface of each guide end body is provided with a connection groove body, the exterior of each guide end body is provided with a guide sleeve, and a plurality of connecting end bodies adopting ring structures are arranged on the inner walls of the guide sleeves; a second connection thread is arranged on the outer wall of each guide sleeve, and each second connection thread and the corresponding first connection thread are connected ina meshed manner; and by means of the guide system used for the injection mold and using the rotary guide structure, guide connection processing of the guide system is realized in a thread rotary connecting manner between the fixed mold and movable mold, and the overall guide accuracy is significantly increased.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to a guiding system for injection molds adopting a rotating guiding structure. Background technique [0002] Injection molds are molds used to produce plastic products, which can give plastic products complete structure and precise dimensions. In the production process of existing injection molds, it is often necessary to move the movable mold towards the fixed mold driven by the injection molding equipment, so that the injection molding machine can be formed; in order to ensure good positional stability between the fixed mold and the movable mold , so it is necessary to set up a guiding system to assist in guiding processing; however, the existing guiding systems often use linear motion components for guiding processing, which has insufficient guiding accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
