Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to an energy-saving heating mechanism for a rubber machine. Background Art

[0002] Injection molds usually heat the mold plates. The general structure is as follows: a hot plate is fixedly installed on the moving template, a drag plate is placed above the hot plate, and a mold plate is provided on the drag plate. During injection molding, the mold plate is heated by the hot plate (heating wires are installed in the hot plate), so that the mold plate reaches a predetermined temperature. However, sometimes mold moving operations are required, such as taking products or placing inserts, etc. At this time, the drag plate will move away from the hot plate by the push of the oil cylinder and the support of the slide rail structure, and after taking the product or placing the insert, it is pushed back onto the hot plate by the oil cylinder. In the above process, the heating surface of the hot plate is exposed, resulting in accelerated heat loss, and the fact that the hot plate cannot directly heat the mold plate will also cause heat loss, leading to increased energy consumption and lack of energy conservation and environmental protection. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an energy-saving heating mechanism for a rubber machine.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

However, the present disclosure can be embodied in different forms and should not be construed as limited to the implementation schemes set forth herein. On the contrary, these implementation schemes are provided so that the present disclosure will be comprehensive and complete, and will fully convey the scope of the present disclosure to those skilled in the art. In addition, the present disclosure is only limited by the scope of the claims.

[0017] The shapes, sizes, proportions, angles, and numbers disclosed in the drawings used to describe the implementation schemes of the present disclosure are only examples, so the present disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, when the detailed description of related known functions or configurations is determined to unnecessarily obscure the key points of the present disclosure, the detailed description will be omitted. In the case of using "comprising", "having", and "including" described in this specification, unless "only" is used, other components can be added. Unless otherwise indicated, terms in the singular form can include the plural form.

[0018] When interpreting elements, although not explicitly described, the elements are understood to include an error range.

[0019] When describing the positional relationship, for example, when the positional relationship is described as "on...", "above...", "below...", and "adjacent to...", unless "immediately" or "directly" is used, one or more other parts can be arranged between the two other parts.

[0020] When describing a time relationship, for example, when a time sequence is described as “after,” “subsequently,” “next,” and “before,” discontinuous cases may be included unless “just” or “directly” is used.

[0021] 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 only used 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 the present disclosure.

[0022] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0023] Reference Figures 1 to 3 The utility model discloses an energy-saving heating mechanism for a rubber machine, comprising a driving unit 1, a slide rail structure, a carriage 2, a hot plate 3, a movable template 4 and a mold plate (not shown in the figure), a pad 5 fixed to the movable template 4 is provided between the carriage 2 and the movable template 4, because the carriage 2 will have a distance to generate friction with the movable template 4 during the process of mold transfer, and thus a pad 5 is provided to protect the movable template 4, and the pad 5 can be made of softer metal, such as copper or aluminum.

[0024] As shown in the figure, the carriage 2 can be moved to or away from the pad 5 by the driving of the driving unit 1 and the sliding support of the slide rail structure. The above process realizes the process of mold shifting. The hot plate 3 is fixed on the carriage 2. Of course, the present application fixes the hot plate 3 to the carriage 2 by screws, and the movable mold plate 4 is also set on the hot plate 3 by screws. A number of heating tubes or heating wires are provided in the hot plate 3, so that the mold plate can be heated. Of course, the heating structure of the hot plate 3 has not changed and is the prior art, so it is not described in detail. The driving unit 1 is preferably a hydraulic cylinder.

[0025] Of course, because the hot plate 3 now needs to be moved outside the injection station, the bottom surface of the hot plate 3 will be exposed to the outside world. Although there is a drag plate 2 for isolation, the heat loss will be greater than before when it does not move. Therefore, a bottom insulation plate 6 is fixed between the hot plate 3 and the drag plate 2 by screws. The bottom insulation plate 6 can greatly reduce the heat loss of the bottom surface of the hot plate 3 after it is moved out of the injection station. The bottom insulation plate 6 is preferably made of glass fiber material and a highly heat-resistant composite material. Of course, the above-mentioned materials are also available. As a preference, side insulation plates 7 are fixed around the hot plate 3 by screws, which reduces the heat loss around the hot plate 3 and reduces energy consumption.

[0026] As shown in the figure, the slide rail structure includes a guide rail 8 relatively fixed on the movable mold plate 4, and a plurality of bearings 9 are arranged on the guide rail 8. The bearings 9 are fixed on the inner side of the guide rail 8 by screws. Of course, the highest point of the outer ring of the bearing 9 is slightly higher than the pad 5. When the mold is moved, the driving unit 1 drives the carriage 2 to move. After the carriage 2 moves a certain distance, it will be squeezed with the outer ring of the bearing 9 and move to the top of the bearing 9. The bottom surface of the carriage 2 can roll and rub with the bearing 9, and is supported by the bearing 9 and continues to move until it moves into place.

[0027] As shown in the figure, a guide bar 10 is provided on the guide rail 8, and a guide groove 11 cooperating with the guide bar 10 is provided on the side wall of the carriage 2. The guide bar 10 cooperates with the guide groove 11 to guide the carriage 2 to move along the guide rail 8. For greater reliability, a guide groove 2 12 is provided on the side of the guide bar 10, and the groove wall of the guide groove 11 is inserted into the guide groove 2 12. In this way, the guide bar 10 and the carriage 2 form a mutually interlocking structure, which improves the reliability of the cooperation and prevents the carriage 2 from derailing.

The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
