Technical Field

[0001] The invention relates to the field of molds, and in particular to a mold which is convenient for rapid cooling. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed. It is known as the "mother of industry".

[0003] When the mold is in use, it will cool down the injection molded workpiece. There are many ways to cool down the workpiece, one of which is water cooling. When water enters the mold, the heat is transferred to the water, but the heat cannot be transferred to the water evenly. In this way, the cooling water cannot be fully utilized to cool down the mold. It takes a certain amount of time for the cooling water to fully absorb the heat of the mold, which will affect the processing efficiency. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by arranging the mold body, the cover plate and the piston assembly to cooperate with each other, when the cooling water enters the cooling tank through the water inlet pipe, a part of the heat of the mold will be absorbed by the cooling water. In this process, the heat cannot be evenly distributed in the cooling water. The electric telescopic rod is started by an external device, so that the plug is close to the electric telescopic rod. At this time, part of the cooling water flows into the liquid storage pipe, and the flowing cooling water can drive the spiral rod to rotate, so that the cooling water can be stirred for the first time.

In this way, the cooling water can be efficiently used to quickly cool the mold. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-5 A mold that is easy to cool quickly is shown, including a mold body 1, a cover plate 2, a piston assembly 3, a cushion block 4 and a base 5.

[0022] A mold groove 101 is provided on the upper surface of the mold body 1, a cooling groove 102 is provided on the upper surface of the mold body 1 and located at the periphery of the mold groove 101, spiral rods 104 are movably installed on both sides of the cooling groove 102, a threaded groove 103 is provided on the upper surface of the mold body 1 and near the four corners, a water inlet pipe 105 is fixedly installed on the front surface of the mold body 1 and near the other side, a drain pipe 106 is fixedly installed on the front surface of the mold body 1 and located below the water inlet pipe 105, and a through hole 107 is provided on one side surface of the mold body 1. When the piston assembly 3 draws the cooling water in the cooling groove 102 into the liquid storage pipe 301, the flowing cooling water can drive the spiral rod 104 to rotate, so that the cooling water can be stirred for the first time, so that the cooling water can be better used to cool the mold. When the piston assembly 3 pushes the cooling water out of the liquid storage pipe 301, the flowing cooling water can drive the spiral rod 104 to rotate again, so that the heat can be evenly distributed in the cooling water; the upper surface of the cover plate 2 A rotating groove 201 is provided on the surface and near the four corners, a rotating rod 203 is movably embedded in the rotating groove 201, a rotating ring 204 is fixedly sleeved on the surface of the rotating rod 203 and near the upper end, and a guide rod 202 is fixedly installed on the upper surface of the rotating rod 203; the piston assembly 3 includes a liquid storage tube 301, an electric telescopic rod 302 and a plug block 303, the front surface of the liquid storage tube 301 is fixedly installed with the electric telescopic rod 302, the telescopic end of the electric telescopic rod 302 extends into the liquid storage tube 301, and the electric telescopic rod 302 is fixedly installed on the upper surface of the liquid storage tube 301. The plug 303 is fixedly installed at the telescopic end of the piston 202. The electric telescopic rod 302 can control the plug 303 to make piston movement in the liquid storage tube 301, so as to draw and push the cooling water in the cooling tank 102 into and out of the liquid storage tube 301; the piston assembly 3 is fixed to the mold body 1 through the liquid storage tube 301, and the liquid storage tube 301 is connected to the cooling tank 102 through the through hole 107; the surface of the rotating rod 203 and below the rotating ring 204 are provided with threads, and the lower end of the rotating rod 203 is embedded in the thread groove 103. Preferably, there are two spiral rods, which are respectively arranged on both sides of the piston assembly, and the spiral directions of the blades on the spiral rods are the same, so as to push the water to flow in the same direction, for example, clockwise.

[0023] It should be noted that the present invention is a mold that is easy to cool quickly. When in use, when the cooling water enters the cooling tank 102 through the water inlet pipe 105, a part of the heat of the mold will be absorbed by the cooling water. In this process, the heat cannot be evenly distributed in the cooling water. The electric telescopic rod 302 is started by an external device, so that the plug 303 is close to the electric telescopic rod 302. At this time, part of the cooling water flows into the liquid storage tube 301, and the flowing cooling water can drive the spiral rod 104 to rotate, so that the cooling water can be stirred for the first time. In this process, the stirred cooling water can continue to absorb heat better. When the piston assembly 3 pushes the cooling water out of the liquid storage tube 301, the flowing cooling water can drive the spiral rod 104 to rotate again, so that the cooling water is stirred again, and in this way until the cooling water stays in the cooling tank 102 for a set time and then is discharged. In this way, the cooling water can be efficiently used to quickly cool down the mold.

[0024] A directional assembly for directional flow of the coolant may be provided in the cooling tank, and the directional assembly includes a baffle 701, a movable plate 702, a rotating shaft 703, and a limiting plate 704, wherein the movable plate is rotatably connected to the outer wall of the cooling tank through the rotating shaft, the baffle is fixed to the inner wall of the cooling tank, the baffle is located on the side of the movable plate away from the piston assembly, and the side of the movable plate close to the piston assembly is fixedly connected to the limiting plate. When the electric telescopic rod becomes shorter, the coolant pushes the movable plate to rotate toward the piston assembly until the end of the limiting plate away from the movable plate abuts against the outer wall of the cooling tank. At this time, there is a gap between the movable plate and the baffle, and the coolant passes through the gap and enters the liquid storage tube 301. When the electric telescopic rod becomes shorter, the coolant pushes the movable plate to rotate toward the baffle until the movable plate abuts against the baffle, cutting off the cooling tank, thereby forcing the coolant to flow to the side of the unset directional assembly. The movable plate and the wall of the cooling tank where the movable plate is located are at an angle, and the angle is preferably 30°-90°. That is, when the limit plate is against the groove wall, it is 30°, and when the movable plate is against the baffle, it is 90°. Therefore, there is no need to set up a separate component to drive the movable plate. This structure is also conducive to increasing the pressure of the coolant in the cooling tank, so that the pressure of the coolant can better drive the screw rod to rotate, and at the same time, the impurities or scale in the screw rod or the cooling tank can be impacted. The rotation of the screw rod can also cause the coolant to be subjected to the action of centrifugal force, thereby impacting the upper part of the cooling tank, thereby allowing the coolant to not completely fill the cooling tank. The width of the baffle is preferably not more than one-fourth of the width of the cooling tank. The width of the movable plate is preferably not less than one-fifth of the width of the cooling tank. Thereby, it is ensured that the movable plate and the baffle can be against each other, and the gap between the two is ensured when they are opened. Preferably, the directional assembly also includes a square frame, and the movable plate and the baffle are both connected to the square frame. The outer contour of the square frame is interference fit with the inner contour of the cooling tank, so as to facilitate the installation of the movable plate and the baffle. Yes, a limited support is connected to the square frame, the end of the liquid storage tube is exposed in the cooling tank, and the limited support is against the liquid storage tube. This interferes with the positioning of the square frame.
