Background technique

Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape, and the application of the contour shape with cutting edges can separate the blank according to the contour line shape, and the application of the inner cavity shape can make the blank obtain a corresponding three-dimensional shape. It is cumbersome to take out the existing plastic injection mold during injection molding, and the position cannot be moved. Therefore, we propose a more practical plastic injection mold.

In order to achieve the above object, the utility model provides the following technical solutions: a mold for plastic injection molding, including a mold upper cover, a moving guide rail, a cooling pipe and a push rod, the bottom of the mold upper cover is equipped with a mold main body, and the mold main body The two sides of the mold body are provided with fixed rods, the moving guide rails are connected with the fixed rods, reinforcing ribs are installed on both sides of the mold body, and the bottom end of the mold body is provided with a mold bottom plate, and the cooling pipe is placed on the bottom of the mold bottom plate. Below, and the bottom side of the cooling pipe is fixed with a buffer block, the bottom of the buffer block is provided with a vent hole, the push rod is embedded in the bottom end of the mold body, and the push rod is connected with the connecting pin, the mold body A vibration transmission rod is fixed on the lower right, and the outer wall of the upper cover of the mold is provided with an injection port, and a limited hole is installed on the left side of the injection port.

Preferably, the cooling pipe is designed in a curved shape.

Preferably, the push rod is a telescopic device, and the telescoping range is 0-10cm.

Preferably, the connecting pin is a detachable device.

Preferably, an overflow port is provided at the bottom of the limiting hole.

Compared with the prior art, the beneficial effect of the utility model is that the structure of the mold for plastic injection molding is simple and novel, the position of the mold can be conveniently fixed by the fixing rod during the injection molding process, and the mold can move up and down with the moving guide rail, effectively increasing the The flexibility of the injection molding process and the design of the cooling pipe can effectively dissipate the high-temperature heat generated during injection molding, and the cooling pipe is designed in a curved shape, which increases the contact area between the cooling pipe and the mold, thereby improving the effect of heat dissipation. There are reinforcing ribs on both sides, which can ensure the firmness of the injection mold and prevent the mold from cracking during use. After the injection molding is completed, the push rod can be stretched to separate the mold from the object quickly and prevent the molded object from staying in the mold. The quality is affected, and the limit hole can accurately fix the position of the injection molding machine, which greatly improves the practicability of the injection mold.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a mold for plastic injection molding, including a mold upper cover 1, a mold body 2, a fixed rod 3, a moving guide rail 4, a reinforcing rib 5, a mold bottom plate 6, a cooling Tube 7, buffer block 8, vent hole 9, push rod 10, connecting pin 11, vibration conduction rod 12, injection molding port 13, limit hole 14 and overflow port 15, the bottom end of mold upper cover 1 is equipped with mold main body 2, And the both sides of mold main body 2 are provided with fixed bar 3, and moving guide rail 4 is connected with fixed bar 3, and the both sides of mold main body 2 are provided with reinforcing rib 5, and the bottom end of mold main body 2 is provided with mold bottom plate 6, and cooling pipe 7 is placed under the mold bottom plate 6, and the bottom side of the cooling pipe 7 is fixed with a buffer block 8, the cooling pipe 7 is designed in a curved shape, the bottom of the buffer block 8 is provided with a vent 9, and the push rod 10 is embedded in the mold body 2 The bottom end, and the push rod 10 is connected with the connecting pin 11, the connecting pin 11 is a detachable device, the push rod 10 is a telescopic device, and the telescopic range is 0-10cm, and the bottom right of the mold body 2 is fixed with a vibration conducting rod 12 , the outer wall of the mold upper cover 1 is provided with an injection port 13, and a limit hole 14 is installed on the left side of the injection port 13, and an overflow port 15 is provided at the bottom of the limit hole 14.
