Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is only intended to illustrate and explain embodiments of the present invention, and is not intended to limit embodiments of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, bottom" and "upper" are generally used with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, vertical or gravitational direction.
The invention will be described in detail below with reference to the accompanying drawings in conjunction with exemplary embodiments.
Referring to fig. 2 through 8, a first exemplary embodiment of the present invention provides an injection molding machine mold plate 100, the injection molding machine mold plate 100 including a mold plate code surface for fixing or clamping an injection molding machine mold. Wherein, the template code mold surface is at least partially formed with a crimping convex surface 11 protruding along the thickness direction of the injection molding machine template 100 in the central area, and the protruding amount or the specific protruding shape of the crimping convex surface 11 can be determined based on finite element simulation analysis or actual detection. Further, the crimp convex surface 11 may be formed by performing cutting work on the template code surface to form the crimp convex surface 11, for example, cutting from the periphery to the center at the time of the work so that the center protrusion thickness of the template code surface is larger than the center outer protrusion thickness. In the mold-closed state of the injection molding machine mold 200, the pressure contact convex surface 11 can be always brought into pressure contact with the mold mounting surface of the injection molding machine mold 200 whose center is aligned.
As can be seen, when the injection molding machine mold plate 100 is subjected to bending deformation by mold clamping force and pressing force from the injection molding machine mold during operation of the injection molding machine provided with the injection molding machine mold plate 100, the pressure contact convex surface can be formed into a shape such as a flat surface that contacts the mold mounting surface under pressure, thereby ensuring contact pressure contact with the mold mounting surface. In other words, by arranging the compression joint convex surface, a gap can be prevented from being formed between the template die stacking surface and the die mounting surface, and the tightness of the die in the cavity injection process is ensured, so that flash is prevented from being formed in the injection molding product, and the molding quality of the injection molding product is improved.
Referring to fig. 2 and 3, the convex crimping surface 11 may be formed as a continuous curved surface, and the convex thickness of the convex crimping surface 11 in the thickness direction gradually increases from the outer periphery to the center. Specifically, in the first example shown in fig. 2, the template code surface may be formed as the crimp convex surface 11, i.e., the entire template code surface may be formed as the crimp convex surface 11. In the second example shown in fig. 3, the outer region of the template code surface on the convex crimping surface 11 may be formed as an outer flat surface 12, and the inner edge of the outer flat surface 12 may be connected to the outer edge of the convex crimping surface 11. In other words, the template code surface in the present example may be composed of the convex crimping surface 11 and the outer side plane 12, and since the area of the convex crimping surface 11 is smaller than that in the first example, the difficulty of processing can be reduced.
Referring to the third example shown in fig. 4, the convex crimping surface 11 may be formed as a tapered surface, and in order to reduce the difficulty of processing, a portion of the template code surface located outside the convex crimping surface 11 may be formed as an outer flat surface 12, and an inner edge of the outer flat surface 12 may be connected to an outer edge of the convex crimping surface 11. Since the area of the crimping convex surface 11 in this example is relatively small, and the crimping convex surface 11 is a plane rather than a curved surface, the processing difficulty is smaller, and the improvement of the production efficiency and the saving of the production cost are facilitated.
Referring to a fourth example shown in fig. 5, the injection molding machine mold plate 100 may further include a spacer 13, one side wall surface of the spacer 13 being fitted to a central groove portion formed on the mold plate code surface and the other side wall surface being formed as a press-contact convex surface 11. Compared with the method of directly processing the crimping convex surface 11 on the template code mold surface, the injection molding machine template 100 in the example can process the crimping convex surface 11 on the cushion piece 13 with smaller volume, and the situation that the injection molding machine template 100 needs to be discarded due to processing errors can not occur, so that the method has the advantages of small processing difficulty, larger fault tolerance rate in the production and processing process and the like.
With the injection molding machine mold plate 100 according to the first exemplary embodiment of the present invention, the outer contour of the crimping convex surface 11 may be set to different shapes, for example, may be set to be circular or polygonal, etc., according to actual conditions.
Referring to the fifth example shown in fig. 6, a plurality of template step layers 14 that protrude layer by layer in the thickness direction and decrease in the outer dimension layer by layer may also be formed on the template code surface, and at this time, the plurality of step surfaces in the plurality of template step layers 14 collectively form the crimping convex surface 11. Compared with the machining of a continuous curved surface, the stepped crimping convex surface 11 of the present example has smaller precision requirements, so the machining difficulty is smaller, and the machining operation is easier to implement.
Similarly, the outer contour of the template stage layer 14 may be set to different shapes based on actual conditions, such as a circle or a polygon.
Referring to fig. 9, a second exemplary embodiment of the present invention provides a mold clamping apparatus including an injection molding machine mold 200 and the injection molding machine mold plate 100 described above. It can be seen that, in the mold closing state of the injection molding machine mold 200, the pressing convex surface 11 is in pressing fit with the mold mounting surface of the injection molding machine mold 200 aligned with the center, so as to ensure that the mold parting surface 21 is kept closed, thereby preventing flash from being formed in the injection molding product to ensure the molding quality of the injection molding product.
Furthermore, the utility model discloses third exemplary embodiment provides an adopt foretell MOLD CLAMPING APPARATUS's injection molding machine, owing to adopted in this injection molding machine the utility model discloses injection molding machine template 100 in the first exemplary embodiment consequently possesses all advantages that this injection molding machine template 100 brought, and here is no longer repeated repeatedly.
The above describes in detail optional implementation manners of embodiments of the present invention with reference to the accompanying drawings, however, the embodiments of the present invention are not limited to the details in the above implementation manners, and in the technical concept scope of the embodiments of the present invention, it is possible to perform various simple modifications on the technical solutions of the embodiments of the present invention, and these simple modifications all belong to the protection scope of the embodiments of the present invention.
It should be noted that, in the above-mentioned embodiments, the various technical features described in the above-mentioned embodiments can be combined in any suitable way without contradiction, and in order to avoid unnecessary repetition, the embodiments of the present invention do not separately describe various possible combinations.
In addition, various different implementation manners of the embodiments of the present invention can be combined arbitrarily, and as long as it does not violate the idea of the embodiments of the present invention, it should be considered as the disclosure of the embodiments of the present invention.
