Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a quick prototyping mold with replaceable cores. Background Art

[0002] A mold is a tool for making formed articles. A mold core is a precision part for key operations in the central part of the mold. The mold core and the mold cooperate with each other to compress and form the product. Generally, the structure of the mold core is complex, the processing difficulty is very high, and the cost is very high. Often, the labor cost for manufacturing is much higher than the material itself. Currently, when using a handle injection mold, there is one mold core for one mold, and there are also molds with replaceable mold cores.

[0003] The utility model with the application number CN202223580831.X relates to the field of die-casting molds, and particularly relates to a die-casting mold with replaceable cores, including a fixed mold, a hollow mold core and a mold core. The hollow mold core is fixedly installed in the fixed mold. Two clamping components are symmetrically arranged at the bottom of the mold core. Two clamping holes adapted to the clamping components are formed in the hollow mold core. A driving device is fixedly installed on the side surface of the fixed mold. An unlocking component is arranged in the hollow mold core. The output end of the driving device is connected with the unlocking component. By using the cooperation between the clamping components and the clamping holes, the utility model can realize the fixed installation of the mold core on the hollow mold core, and drive the unlocking component to move through the driving device, so as to realize the unlocking of the buckling connection between the unlocking component and the clamping holes, thereby facilitating the removal of the mold core from the inside of the fixed mold, facilitating the quick replacement of the mold core, and effectively improving the working progress of the staff.

[0004] This application drives the buckle to engage through an oil cylinder, so as to quickly replace the core. However, when replacing the core, the center positioning of the mold core cannot be carried out. When the mold die-casts and forms the workpiece, the position of the workpiece placed in the mold will affect the forming quality of the workpiece. When the mold core is not in the center position, the workpiece is unbalanced in force and is prone to an inclined state during forming.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a quick prototyping mold with replaceable cores that can effectively solve the above technical problems.

[0025] As Figures 1 to 5 shown, a quick prototyping mold with a replaceable core includes: an upper cover plate 1 for installing the mold, and a forming assembly 2 for forming a workpiece.

[0026] The upper cover plate 1 includes a plate body 11, a clamping component 12, and a positioning rod 13; the clamping component 12 is composed of a locking member 121, a first clamping plate 122, a second clamping plate 123, a spring 124, and a rotating shaft 125; the bottom of the locking member 121 is provided with threads, the plate body 11 is threadedly connected to the locking member 121, the positioning rod 13 is fixedly connected to the plate body 11, the locking member 121 is slidably connected to the first clamping plate 122, the first clamping plate 122 is fixedly connected to the second clamping plate 123, and there are two sets of the first clamping plate 122 and the second clamping plate 123. The two sets of clamping plates are fixedly connected to the spring 124, and the spring 124 is placed in the middle of the two sets of second clamping plates 123. Both the first clamping plate 122 and the second clamping plate 123 are rotatably connected to the rotating shaft 125. Two sets of columns are also installed on the top of the locking member 121; when the mold needs to be re-cored, the staff manually rotates the two sets of columns counterclockwise, and at the same time presses the second clamping plate 123 to make the second clamping plates 123 approach each other. At the same time, according to the lever principle, the first clamping plate 122 and the second clamping plate 123 rotate around the rotating shaft 125, and the first clamping plates 122 move away from each other, so that the locking member 121 is disengaged from the plate body 11. Since the mold is a layered structure, the whole mold can be disassembled at this time, and the inner core can be replaced at the same time.

[0027] As a supplement: when the mold core needs to be installed, by rotating the two sets of columns clockwise, the locking member 121 is fitted into the inside of the plate body 11, and the first clamping plate 122 clamps the locking member 121, so that the two sets of first clamping plates 122 abut against the outer edge of the locking member 121. At the same time, horizontal and vertical fixing members are installed on the first clamping plate 122 to limit the locking member 121 horizontally and vertically, and the distances between the two sets of first clamping plates 122 when they contact the locking member 121 are the same, so as to position the locking member 121 and keep the center of the locking member 121 always at the center position, so that the bottom of the locking member 121 always contacts the four sets of molds to keep the mold balanced for the forming of workpieces.

[0028] The forming component 2 is composed of a mounting frame 21, a fixing plate 22, a positioning column 23, and a forming table 24; the mounting frame 21 is fixedly connected to the fixing plate 22, the positioning column 23 is fixedly connected to the forming table 24, positioning grooves are opened at the four corners of the fixing plate 22 and can cooperate with the positioning rod 13, the forming table 24 is divided into upper and lower layers, and a groove is opened in the center of the positioning column 23 and is threadedly connected to the center of the locking member 121; the mounting frame 21 is used to fix the side of the forming table 24. When the locking member 121 is disengaged from the plate body 11, the forming table 24 can be separated, and the positioning column 23 at its center is disengaged from the locking member 121 to disassemble and assemble the whole mold, so that the whole mold can be disassembled;

[0029] At the same time, lifting the plate body 11 can also separate the plate body 11 from the fixing plate 22 to reduce the separation difficulty. At the same time, the base 3 can fix the forming table 24 to prevent the bottom of the forming table 24 from slipping off.

[0030] Working principle:

[0031] When the mold needs to be re-cored, the staff manually rotates two sets of columns counterclockwise, and at the same time presses the second engaging plate 123 to make the second engaging plates 123 approach each other. At the same time, according to the lever principle, the first engaging plate 122 and the second engaging plate 123 rotate around the rotating shaft 125, and the first engaging plates 122 move away from each other, so that the locking member 121 disengages from the plate body 11. Since the mold is a layered structure, the whole mold can be disassembled at this time, and the inner core can be replaced. The mounting frame 21 is used to fix the side of the forming table 24. When the locking member 121 disengages from the plate body 11, the forming table 24 can be separated, and the positioning column 23 at its center disengages from the locking member 121 to disassemble and assemble the whole mold, so that the whole mold can be disassembled.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
