Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely with reference to fig. 4 and 5 of the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

For a clearer explanation, the present embodiment is described with reference to a direct joint mold, and as shown in fig. 4 and 5, a PVC pipe joint forming mold includes a mold plate 1, where the mold plate 1 is made of a ferrous material, and is usually formed by grinding a square iron block to form a hole and a groove. The die plate 1 is provided with a feed inlet 10 and a forming cavity 13 in a penetrating way, and a feed chute is arranged on the surface of one side of the die plate. The forming chamber 13 is connected to the feed chute via an oblique feed opening 14. The inclined feed hole 14 is located at one side of the forming cavity 13, the top of which is not in communication with the forming cavity 13, and only the bottom of which is in communication with the forming cavity. The central axis of the oblique feeding hole 14 forms an included angle of 15-45 degrees, preferably 30 degrees with the surface of the template 1. That is, the slant feed hole 14 is obliquely inserted into the molding cavity 13.

Specifically, in order to facilitate the processing and improve the production efficiency, the feed chute includes a main feed chute 11 and a branch feed chute 12, and the feed inlet 10 is connected with the branch feed chute 12 through the main feed chute 11. Two adjacent forming cavities 13 are communicated with each other through a branch feeding groove 12 and two oblique feeding holes 14. The inclined feeding hole 14 penetrates through one side wall of the forming cavity 13, and the top of the inclined feeding hole 14 is communicated with the branch feeding groove 12.

In order to reduce the contact surface and ensure the beauty of the final product, the inclined feeding hole 14 is in a conical structure, and the top is small and the top is large. The forming cavity 13 of the direct joint is of a cylindrical cavity structure.

Of course, as in the prior art, the mold should further include an ejection mechanism movably disposed on the other side of the mold plate 1, having a shape matching the molding cavity 13 of the mold plate 1, and capable of being inserted into the molding cavity 13 to eject the product in the molding cavity 13. The ejection mechanism can be directly designed without modification.

During production, raw materials are injected from the feed inlet 10 after the mold is closed, the raw materials flow into the branch feed grooves 12 from the main feed groove 11, and then flow into the molding cavity 13 from the inclined feed holes 14 at the end parts of the branch feed grooves 12. After the forming cavity 13 is filled with the raw materials, after the raw materials are cooled to reach a preset temperature, the mold is opened, the cooled products are ejected out of the forming cavity 13 by the ejection mechanism, a certain shearing force is formed between the material column in the oblique feeding hole 14 and the products when the products are ejected out due to the fact that a certain inclination exists between the oblique feeding hole 14 and the forming cavity 13, the material column is automatically cut off after the products are extruded, and the final pipe joint 21 is free of manual cutting.

The utility model discloses an ingenious design, with original feed chute and the mode that becomes die cavity 13 and directly communicate at the template upper surface change into and adopt slant feed port 14 to connect, the stock column of automatic cutout pan feeding mouth when extrusion mechanism extrudes the product to a large amount of cost of labor have been saved, the qualification rate of product has been improved.
