Description

Technical Field

[0001] The utility model belongs to the technical field of plastic mold products, and in particular relates to a telescopic mechanism which can move in an inclination direction. Background Art

[0002] A telescopic mechanism is a structure that can adjust the length or change the shape. It achieves its function by increasing or decreasing the distance between components or adjusting the length of components. This mechanism is particularly important in situations where it is necessary to adjust the size of a space or change the shape of an object.

[0003] In the field of mold manufacturing, the telescopic mechanism can be used for demoulding the inner thread of the bottle cap membrane, as well as complex operations such as demoulding the entire circle of undercuts, to improve production efficiency and product quality. Due to the existence of various undercuts in plastic mold products, the complexity of the products makes it difficult for the products to be demoulded smoothly. In order to improve the producibility of the products, a new mold buckle position structure is designed to enable smooth product production.

[0004] After searching, the "a telescopic cover" disclosed in the application number "CN202221603405.0" belongs to the same technical field as the present technical solution. The utility model pushes the telescopic core to move in the telescopic sleeve, so that the telescopic sleeve expands radially and the product is successfully demoulded. The structure is simple and convenient. The telescopic sleeve and the flange assembly are detachably connected, which is easy to assemble and can improve work efficiency. The telescopic sleeve is a split structure, which is convenient for maintenance and replacement.

[0005] During the use of the existing telescopic cage mechanism, when the plastic mold is designed with an ordinary telescopic cage, the slider in the telescopic cage can only move horizontally. When the product buckle position needs to be demolded at an angle, the product and the slider will interfere, making the product unable to be demolded or damaging the product structure. Utility Model Content

[0006] The utility model aims to provide a telescopic mechanism that can move in an inclined direction, aiming to solve the problem in the prior art that the slider in the existing telescopic mechanism can only move in a horizontal direction, and when the product buckle position needs to be demolded at an inclined angle, the product and the slider will interfere, thereby making the product unable to be demolded or damaging the product structure.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a telescopic mechanism that can move in an inclined direction, comprising a first pressing block, a second pressing block, a third pressing block and a center pressing block, wherein the second pressing block is arranged on the bottom side of the first pressing block, the third pressing block is arranged on the bottom side of the second pressing block, and the first pressing block, the second pressing block and the third pressing block are penetrated by the center pressing block;

[0008] The side surface of the center frame is connected to a first guide rail, a first slider is arranged on the outer side of the center frame, a first guide groove is provided on the side surface of the first slider close to the first guide rail, a first limit block is connected to the outer surface of the first slider, a second slider is arranged on the side surface of the center frame, an inner wall of the second slider is connected to a second guide rail, a second guide groove is provided on the side surface of the center frame close to the second guide rail, and a second limit block is connected to the outer surface of the second slider.

[0009] As a preferred telescopic mechanism of the utility model that can move in an inclined direction, the first guide rail, the first slider, the first guide groove and the first limit block are arranged in four groups, and the first guide rail, the first slider, the first guide groove and the first limit block are distributed in a circular array with the central axis of the center rail as the center.

[0010] As a preferred telescopic mechanism of the utility model that can move in an inclined direction, the first slider is slidably connected to the first guide rail through the first guide groove, the first slider and the first limit block are an integral structure, and the first guide rail is obliquely arranged.

[0011] As a preferred telescopic mechanism of the utility model that can move in an inclined direction, the second slider, the second guide rail, the second guide groove and the second limit block are arranged in four groups, and the second slider, the second guide rail, the second guide groove and the second limit block are distributed in a circular array with the central axis of the center lever as the center.

[0012] As a preferred embodiment of the telescopic mechanism of the utility model that can move in an inclined direction, the second guide slide rail is slidably connected with the center slide rail through the second guide slide groove, and the second guide slide rail is arranged obliquely.

[0013] As a preferred embodiment of the telescopic mechanism of the utility model that can move in an inclined direction, the second sliding block and the second limiting block are an integrated structure.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] According to the utility model, when the center bracket is contracted, the first limit block can be driven by the first guide slide rail and the first guide slot to realize oblique movement toward the center; at the same time, the second limit block can be driven by the second guide slot and the second guide slide rail to realize oblique movement toward the center. Since the inclination angles of the first guide slide rail and the second guide slot are different, the downward movement distances of the two are different, so that the movement between the first slider and the second slider will not affect each other. Through this structure, the first slider and the second slider can be moved at an oblique angle. This telescopic bracket oblique-out mechanism can complete the oblique buckling position required for the product, subverting the fact that the ordinary telescopic bracket position mechanism can only move in the horizontal direction, thereby improving the manufacturability of the product.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 11 The utility model provides the following technical solutions: a telescopic mechanism that can move in an inclined direction, comprising a first pressing block 1, a second pressing block 2, a third pressing block 3 and a center pressing block 4, the second pressing block 2 is arranged on the bottom side of the first pressing block 1, the third pressing block 3 is arranged on the bottom side of the second pressing block 2, and the first pressing block 1, the second pressing block 2 and the third pressing block 3 are penetrated by the center pressing block 4;

[0031] The side surface of the center frame 4 is connected to the first guide rail 5, the outer side of the center frame 4 is provided with a first slider 6, the side surface of the first slider 6 close to the first guide rail 5 is provided with a first guide groove 7, the outer surface of the first slider 6 is connected to a first limit block 8, the side surface of the center frame 4 is provided with a second slider 9, the inner wall of the second slider 9 is connected to the second guide rail 10, the side surface of the center frame 4 close to the second guide rail 10 is provided with a second guide groove 11, and the outer surface of the second slider 9 is connected to a second limit block 12.

[0032] Preferably: four groups of the first guide rail 5, the first slider 6, the first guide slot 7 and the first limit block 8 are arranged, and the first guide rail 5, the first slider 6, the first guide slot 7 and the first limit block 8 are distributed in a circular array with the central axis of the center Ke 4 as the center.

[0033] Preferably, the first sliding block 6 is slidably connected to the first guiding rail 5 via the first guiding groove 7, the first sliding block 6 and the first limiting block 8 are an integral structure, and the first guiding rail 5 is obliquely arranged.

[0034] During specific use, when the center link 4 contracts, it can drive the first guide rail 5 to slide inside the first guide groove 7. Since the first guide rail 5 is inclined, the first slider 6 can gather toward the center during this process. Similarly, under the action of the first limit block 8, the first slider 6 will move downward while gathering, so the first limit block 8 realizes oblique movement toward the center.

[0035] Preferably: four groups of the second slider 9, the second guide rail 10, the second guide groove 11 and the second limit block 12 are arranged, and the second slider 9, the second guide rail 10, the second guide groove 11 and the second limit block 12 are distributed in a circular array with the central axis of the center Ke 4 as the center.

[0036] Preferably, the second guide rail 10 is slidably connected to the center rail 4 through the second guide slot 11, and the second guide rail 10 is obliquely arranged.

[0037] Preferably, the second sliding block 9 and the second limiting block 12 are an integrated structure.

[0038] During specific use, when the center link 4 contracts, it can drive the second guide slot 11 to slide on the surface of the second guide rail 10. Since the second guide slot 11 is in an inclined setting, the second guide rail 10 can gather toward the center during this process. At the same time, under the limiting action of the second limit block 12, the second limit block 12 will move downward while gathering, so the second limit block 12 realizes oblique movement toward the center.

[0039] Working implementation principle: when using the telescopic mechanism that can move in the inclined direction, the telescopic mechanism is mainly divided into two steps to complete the movement structure. When the telescopic mechanism is in the mold closing state, the first slider 6, the second slider 9 and the center slider 4 maintain the original buckle state of the product, so that the injection molding can be completed smoothly; when the mold is opened, the center slider 4 can drive the first guide slide 5 to slide inside the first guide slide groove 7 when it shrinks. Since the first guide slide 5 is inclined, the first slider 6 can gather toward the center during this process. Similarly, under the action of the first limit block 8, the first slider 6 will move downward while gathering, so the first limit block 8 realizes oblique movement toward the center; at the same time, the center slider 4 can drive the second slider 5 to slide inside the first guide slide groove 7 when it shrinks. The guide groove 11 slides on the surface of the second guide rail 10. Since the second guide groove 11 is in an inclined setting, the second guide rail 10 can gather toward the center during this process. At the same time, under the limiting action of the second limit block 12, the second limit block 12 will move downward while gathering, so the second limit block 12 realizes oblique movement toward the center. Since the inclination angles of the first guide rail 5 and the second guide groove 11 are different, the downward movement distances of the two are different, so that the movement between the first slider 6 and the second slider 9 will not affect each other. Through this structure, the first slider 6 and the second slider 9 can be moved at an oblique angle, so that the product can be completely disengaged from the buckle position, and the product can be safely ejected to complete the production.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
