A core-drawing screen cloth structure

Abstract

This utility model discloses a core-pulling and pressing structure for mesh fabric, including a pin plate, a rear template, and an insert. Its key feature is that it further includes an inclined pin and an inclined pin head. The inclined pin head is fixed to both the insert and the inclined pin. The rear template has an inclined sliding hole that slides with the inclined pin. The pin plate and the inclined pin are slidably connected via a sliding guide structure. This utility model changes the side core-pulling mechanism to an inclined pin structure, altering the orientation of the insert's protrusion relative to the mesh fabric. Even when the mesh fabric is deformed, wrinkled, or its shape is unstable, the insert can provide a certain degree of flattening and correction without damaging the mesh fabric.

Description

Technical Field

[0001] This utility model relates to an injection mold, and more particularly to a core-pulling and mesh fabric structure. Background Technology

[0002] As shown in the figure, some special products need to be injection molded together with the mesh fabric 6. Therefore, the mesh fabric is laid in the molding cavity 5 before injection molding and is located below the insert 3 that constitutes the molding cavity. The insert 3 is fixed on the slider 33. The slider 33 is connected to the oil cylinder and the rear template 2 has a groove that matches the slider 33. Therefore, when the mold is opened, the oil cylinder will directly drive the slider 33 and the insert 3 to move in a direction perpendicular to the mold opening direction, thereby realizing the side core pulling action to facilitate the ejection of the subsequent products.

[0003] However, during mold closing, if the mesh fabric 6 below the slider 33 is slightly deformed and wrinkled, the deformed and wrinkled part will form a protrusion higher than the bottom surface of the slider. When the slider returns to its original position, it moves towards the protrusion in a horizontal direction perpendicular to the mold opening direction. As a result, it will push the protrusion from the side of the protrusion, causing the mesh fabric to deform and wrinkle more and more severely, which may damage the mesh fabric 6. Therefore, the requirements for the shape of the mesh fabric 6 during injection molding are also relatively high.

[0004] This application proposes a core-pulling and mesh fabric structure to address the aforementioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a core-pulling and mesh fabric structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A core-pulling mesh fabric structure includes a pin plate, a rear template, and an insert. The structure further includes an inclined pin and an inclined pin head, the inclined pin head being fixed to both the insert and the inclined pin. The rear template has an inclined sliding hole that slides with the inclined pin. The pin plate and the inclined pin are slidably connected via a sliding guide structure.

[0008] The sliding guide structure includes a slide block fixed to the ejector plate and a slide plate fixed to the inclined ejector rod. The slide block has a sliding groove, and the side wall of the sliding groove has a side groove. One side of the slide plate is located in the side groove and slides in cooperation with the side groove.

[0009] The inclined top is provided with a rod hole and a countersunk hole that passes through the rod. The end of the inclined rod is provided with a connecting screw hole, and a connecting screw that mates with the connecting screw hole is provided in the countersunk hole.

[0010] The beneficial effects of this utility model are: the side core pulling structure is changed to an inclined top structure, which changes the direction of movement of the insert relative to the mesh fabric. In the case of mesh fabric deformation, wrinkling and unstable shape, it can also be flattened and corrected to a certain extent by the insert, and will not damage the mesh fabric.

However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Furthermore, this disclosure is limited only by the scope of the claims.

[0019] The shapes, dimensions, scales, angles, and numbers disclosed in the accompanying drawings used to describe embodiments of this disclosure are merely examples, and therefore this disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that such detailed descriptions would unnecessarily obscure the focus of this disclosure. Where the terms “comprising,” “having,” and “including” are used in this specification, additional components may be added unless “only” is used. Unless otherwise indicated, singular terms may include plural forms.

[0020] When interpreting components, even if not explicitly described, the components are understood to include a range of tolerances.

[0021] When describing positional relationships, such as "on," "above," "below," and "adjacent to," one or more parts may be arranged between two other parts unless "immediately following" or "directly" is used.

[0022] When describing temporal relationships, such as when time sequence is described as “after,” “following,” “next,” and “before,” discontinuous cases may be included unless “exactly” or “directly” is used.

[0023] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from other elements. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0024] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0025] Reference Figures 1 to 6 This utility model discloses a core-pulling and pressing mesh structure, including a pin plate 1, a rear template 2, and an insert 3. The rear template 2 has a forming part 4, and the surface of the forming part 4 is also part of the forming cavity 5. The mesh 6 is laid on the surface of the forming part 4. When the forming cavity 5 is filled with adhesive, it will combine with the mesh 6 to form a product 15.

[0026] As shown in the figure, it also includes an inclined ejector rod 7 and an inclined ejector head 8. In this application, in order to ensure the balance of forces, there are two inclined ejector rods 7 arranged opposite each other. The inclined ejector head 8 is fixed to the insert 3 by screws, and the top end of the inclined ejector rod 7 is fixed to the inclined ejector rod 7. The rear template 2 is provided with an inclined sliding hole that slides with the inclined ejector rod 7. The ejector plate 1 and the inclined ejector rod 7 are slidably connected by a sliding guide structure. In this application, the angle between the inclined sliding hole and the mold opening direction is preferably 15 degrees. The mold opening direction is also the direction shown by the vertical single arrow in the figure. The movement direction of the inclined ejector rod 7 is shown by the double arrow in the figure.

[0027] Therefore, through the above structure, after the front template (not shown in the figure) opens along the mold opening direction, the ejector plate 1 also begins to move along the mold opening direction, thereby driving the inclined ejector rod 7 to move in a direction inclined to the mold opening direction. This causes the inclined ejector head 8 and the insert 3 to move in a direction inclined to the mold opening direction, thus enabling the insert 3 to exit from the product 15. Of course, the ejector plate 1 also ejects the product 15 synchronously through the ejector pin 9. When the mold is closed, the movement direction of the insert 3 is opposite. However, when the insert 3 is in its initial position, the height of its bottom surface is much higher than the top of the protrusion of the mesh fabric 6. In subsequent movements, the height gradually decreases until the bottom surface of the insert 3 contacts the top of the protrusion, thereby pressing down or even flattening the protrusion, improving the flatness of the mesh fabric 6, instead of causing the mesh fabric 6 to deform and wrinkle more and more severely as before when the insert 3 was reset. This achieves flattening and correction without damaging the mesh fabric 6, and also reduces the requirements for the shaping of the mesh fabric 6, improving the efficiency of workers installing the mesh fabric 6.

[0028] like Figure 6 As shown, the sliding guide structure includes a slide block 10 fixed to the ejector plate 9 by screws and a slide plate 11 fixed to the inclined ejector rod 7 by screws. The slide block 10 is provided with a sliding groove 12, and the side wall of the sliding groove 12 is provided with a side groove. One side of the slide plate 11 is located in the side groove and slides with the side groove. Therefore, the ejector plate 9 moves in the vertical direction. Therefore, the inclined ejector rod 7 needs to slide horizontally relative to the ejector plate 9 to achieve the inclined ejection without being stuck. The horizontal movement of the inclined ejector rod 7 relative to the inclined ejector rod 7 is achieved by the sliding of the slide plate 11 along the side groove.

[0029] As shown in the figure, the specific fixing structure of the inclined head 8 and the inclined rod 7 is as follows: the inclined head 8 is provided with a rod hole and a countersunk hole that passes through the rod, the end of the inclined rod 7 is provided with a connecting screw hole 13, and the countersunk hole is provided with a connecting screw 14 that mates with the connecting screw hole 13. The above structure is simple to process and easy to install.

[0030] The above provides a detailed description of a core-pulling and mesh fabric structure provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
