Problems solved by technology

[0005] However, in the above-mentioned method, although the guide post not only plays a role in the convenient installation of the hot runner plate and the fixed mold, but also plays a role in protecting the hot nozzle when the hot runner plate is placed, but the guide post directly supports its entire The way of the weight of the fixed mold seat plate and the hot runner plate is easy to damage the guide post, so that the end of the guide post is deformed, thus affecting the guiding function of the guide post

Embodiment 1

[0037] Embodiment 1, a kind of guide post, see attached figure 1 and 2 , the guide post includes a cylinder 1, one end of the cylinder 1 is provided with an installation end 12, and the end of the installation end 12 is provided with an installation threaded hole 121; the other end of the cylinder 1 is an insertion end 11, through which the end is inserted into the The guide post cooperates with the guide hole to realize the guiding function; the end of the guide part is provided with a supporting foot, and the supporting foot can be directly fixed and installed on the end of the insertion end 11, or the supporting foot can be divided into two parts as in the first embodiment. It is a sliding block 22 and a supporting foot, wherein the sliding block 22 cooperates and slides in the sliding cavity 111 of the insertion end 11, and a spring 3 for reset is provided between the sliding block and the bottom of the sliding cavity 111; For details, see the attached figure 2 , an oil...

Embodiment 2

[0039] Embodiment two, a kind of guide post, see attached image 3 and 4 , the difference from Embodiment 1 is that the annular oil groove 13 originally arranged on the outer wall of the cylinder 1 is replaced by the spiral oil groove 14 surrounding the cylinder 1, and the first oil guide passage 51 and the spiral oil groove 14 pass through The third oil guide channel realizes Unicom. The third oil guide channel is arranged at intervals along the axial direction of the first oil guide channel 51, and the oil lubricating groove is arranged as a spiral oil groove 14 spirally rising along the column body 1, and the oil path lubricates The length is long, even if there are burrs and other phenomena in the oil groove, because it is not perpendicular to the guiding direction, but has a certain angle, the influence on the guiding accuracy is smaller than that of the horizontal annular oil groove 13.

Embodiment 3

[0040] Embodiment 3, a hot runner protection structure, see attached Figure 5 , what is used here is the guide post in the first embodiment, of course, the guide post in the second embodiment can also be selected, the hot runner protection structure includes a fixed mold seat plate 6, a hot runner plate 7, and a The hot runner, the hot nozzle 8 of the hot runner protrudes through the hot runner plate 7, and four guide posts in the first embodiment are arranged on the hot runner plate 7, and the length of the column 1 is longer than the length of the hot nozzle 8.

[0041] When installing the hot runner protection structure and the fixed mold, the guide post is installed in alignment with the guide hole on the fixed mold, which realizes the convenient installation effect of the hot runner protection structure and the fixed mold, and through the annular lubricating groove set on the column body 1, When inserting into the guide hole of the fixed mold, the problem of dry friction...

Abstract

The invention discloses a guide column. The guide column comprises a column body. One end of the column body is an insertion end. A supporting foot with the diameter being smaller than that of the insertion end is arranged at the end socket of the insertion end in the axial direction of the column body, and the supporting foot extends out of the insertion end. When the guide column is used as a bearing part to support objects, the supporting foot arranged at the insertion end is supported on the ground, and the insertion end of the column body is prevented from making contact with the ground directly, so that the condition that the insertion end bears excessive weight and then is deformed, and consequently the normal guiding function of the guide column is influenced is avoided; and the diameter of the supporting foot is smaller than that of the insertion end, the support foot does not interfere a guide hole when the guide column is used, and thus the normal guide function of the guide column can be achieved.

Description

technical field [0001] The invention relates to the technical field of moulds, more specifically, it relates to a hot runner protection structure and a guide post thereof. Background technique [0002] For injection molded parts with multiple cavities or large shapes, in order to improve the utilization rate of raw materials and reduce the waste of gate materials, molds with hot runner systems are often used. The hot runner is basically set in the front mold part. The setting method is usually the fixed mold, the hot runner plate and the fixed mold seat plate. The hot runner system is set in the hot runner plate, and then the hot runner plate and the fixed mold seat plate are fixed. There is a cavity for installing the hot runner plate. After the fixed mold is installed on the fixed mold seat plate, the hot runner plate cooperates with the cavity; the hot runner system will be equipped with nozzles, and the nozzles will enter the fixed mold after passing through the hot runn...
