Specific embodiments

[0016] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. The components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] In the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0018] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0019] As Figures 1 to 3 shown, a kind of upper film cover mold of the present embodiment includes a feeding plate 1, an upper die frame 2 and a lower die frame 3 which are arranged in sequence from top to bottom. An upper die core 4 is arranged inside the upper die frame 2, and a lower die core 5 is arranged inside the lower die frame 3. The upper die core 4 and the lower die core 5 are closed to form a product cavity 6. A feeding port 7 is arranged on the feeding plate 1, a feeding hole 8 communicating the feeding port 7 and the product cavity 6 is opened on the upper die core 4, a flow splitting cone 9 is arranged on the lower die core 5, and the flow splitting cone 9 is arranged opposite to the feeding hole 8. The feeding hole 8 is designed at the important key wire picking part of the upper film cover product, ensuring the product quality. The flow splitting cone 9 is designed to be conical, with relatively small and uniform filling resistance and relatively small erosion to the mold. The flow splitting cone 9 is detachably installed on the lower die core 5, which is convenient for later maintenance.

[0020] There are two die feet 11 provided at the lower end of the lower die frame 3. The die feet 11 are connected to the bottom plate 12. There are support columns 13 provided between the lower die frame 3 and the bottom plate 12. The design of the support columns ensures the rigidity requirement of the mold, and the mold is not easily deformed. There is an ejector plate 14 provided between the two die feet 11. The ejector plate 14 is connected to the ejector rod 15, and the ejector plate 14 penetrates into the lower die frame 3; the support column 13 is movably arranged through the ejector plate 14.

[0021] There are three reinforcing rib grooves 10 provided on the upper die core 4. The three reinforcing rib grooves 10 are evenly distributed around the circumference of the flow splitter cone 9. As Figure 4 shown in the schematic diagram of the upper film cover product, in which the upper film cover product forms three reinforcing ribs 17 through the three reinforcing rib grooves 10. Without adding wall thickness, the rigidity of the force-bearing position of the product at this place is enhanced, the product is more stable and does not deform. Some ejector rods are designed under the reinforcing ribs, and the product is more powerful when ejected during production.

[0022] There is a slider 16 provided in the product cavity 6. The slider 16 is installed on the lower die frame 3. The main purpose of setting the slider is to reduce the weight and save materials of the product, ensure the uniform wall thickness of the product, facilitate molding, and also meet the requirements of the die-casting process.

[0023] The present utility model is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they are all within the protection scope of the present utility model.
