[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0017] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like 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 a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

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

[0019] like Figures 1 to 5 As shown, the gas self-closing valve cover mold of this embodiment includes an upper mold 1 and a lower mold 2. The upper mold 1 includes an upper mold core 3, and the lower mold 2 includes a lower mold core 4. The upper mold 1 is provided with a positioning rod 11, and the lower mold 2 is provided with a positioning hole 12 that cooperates with the positioning rod 11. After the upper mold core 3 and the lower mold core 4 are closed, a cavity is formed, and the positioning rod 11 is located in the positioning hole 12 for positioning.

[0020] A feed channel 5 connected to the cavity is provided on the upper mold 1; the cavity includes four rows of product cavity groups, each row of product cavity groups includes four product cavities, totaling 16 product cavities, a branch channel 6 is provided between the first row of product cavity groups and the second row of product cavity groups, a branch channel 6 is also provided between the third row of product cavity groups and the fourth row of product cavity groups, both branch channels 6 are connected to the feed channel 5, each product cavity in each row of product cavity groups is connected to the branch channel 6 on one side thereof, and when working, 16 products can be produced at one time by opening the mold, and the efficiency is greatly improved.

[0021] The product cavity is formed by closing the concave mold 7 of the upper mold core 3 and the convex mold 8 of the lower mold core 4. The convex mold 8 is provided with a material-reducing protrusion 9. The grooves between the material-reducing protrusions 9 are connected to form a reinforced surface groove 10. The material-reducing protrusions 9 correspond to the material-reducing grooves on the gas self-closing valve cover. The reinforced surface grooves 10 correspond to the reinforcing ribs on the gas self-closing valve cover. The reinforcing ribs increase the strength of the product and ensure that the product is not easily deformed during production. By setting the material-reducing grooves, the weight of the improved product is 230 grams per piece, reducing unnecessary cost waste.

[0022] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model.
