Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a mold which is convenient for disassembly and assembly. Background Art

[0002] The mold used for casting or injection molding consists of two parts, namely, a movable mold and a fixed mold. In addition to the two sets of molds, there is also a mechanism for fixing the movable mold so that the movable mold and the fixed mold are tightly connected. For example, Patent No. CN219171485U discloses a mold that is easy to disassemble. The solution uses a screw drive to drive the upper mold to move vertically. Since the distance between the upper mold and the lower mold needs to be greater than the height of the object to remove the object, the upper mold needs to move a large distance, and the number of turns that the screw needs to rotate is also very large. In order to increase the speed of the screw rotation, a motor is used in this solution. Although it can increase the speed of lifting the upper mold, the cost is also greatly increased. If the motor is not used, the screw is manually rotated, which will cause the upper mold to lift very slowly, which is not convenient for demolding;

[0003] The root cause of this dilemma is the screw thread drive mode. For this reason, we have proposed a mold that is easy to disassemble and assemble. Utility Model Content

[0004] The purpose of the present invention is to provide a mold that is easy to disassemble and assemble in order to solve the above problems, as described below.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a conveniently disassembled mold, comprising a base, a fixed mold is arranged on the base, a movable mold is placed on the fixed mold, two fixed plates are fixed on the movable mold, and two pushing components are arranged on the fixed mold, which are respectively used to push the two fixed plates upward;

[0007] Two pressing assemblies are arranged between the fixed die and the movable die for pressing down the movable die;

[0008] The pressing assembly includes a bolt and a fixing block. The fixing block is installed on the movable mold and can be disassembled. The bolt is located on the upper side of the fixing block and the fixing block is pressed down by rotation.

[0009] The above-mentioned mold that is easy to disassemble and assemble is used to assemble the fixed mold and the movable mold together, and the movable mold is pressed downward by the pressing assembly to keep the movable mold and the fixed mold sealed, and the molten metal is injected between the fixed mold and the movable mold through the pouring port. When the molten metal is cooled, the fixed block is removed to avoid interference between the fixed block and the bolts, thereby preventing the movable mold from moving upward.

[0010] By pushing the fixed plate upwards through the pushing component, the pushing component uses the lever principle to easily move the movable mold upwards, so that the inner wall of the movable mold is separated from the surface of the casting, and then the movable mold can be removed by hand.

[0011] Preferably, the pushing assembly comprises a mounting frame, the mounting frame is fixed on the fixed mold, a top plate is rotatably provided on the mounting frame, and the top plate is located below the fixed plate.

[0012] Preferably, the end of the top plate is arc-shaped.

[0013] Preferably, a lever is threadedly connected to the top plate.

[0014] Preferably, there are two fixed plates, which are distributed on both sides of the movable mold.

[0015] Preferably, the movable mold is provided with a handle and a pouring port is opened on the movable mold.

[0016] Preferably, a plurality of positioning holes are provided on the upper side of the fixed mold, and a plurality of positioning columns are fixed on the bottom of the movable mold, and the positioning columns are plugged into the positioning holes.

[0017] Preferably, the pressing assembly comprises a fixing frame and a fixing sleeve, the fixing frame is threadedly connected with a bolt, the fixing sleeve is fixed on the movable mold, a fixing block is inserted in the fixing sleeve, and the lower end of the bolt corresponds to the fixing block.

[0018] The beneficial effects are:

[0019] The movable mold is squeezed downward by the pressing component to maintain a seal between the movable mold and the fixed mold. When demolding, the fixed block is directly removed to avoid interference between the fixed block and the bolts. The fixed plate is pushed upward by the pushing component to separate the inner wall of the movable mold from the surface of the casting. Then the movable mold can be removed by hand. The pushing component uses the principle of leverage to easily move the movable mold upward. This mold not only has a fast demolding speed, but also does not use an electric device, is more reliable, durable and has a low cost. BRIEF DESCRIPTION OF THE DRAWINGS
