Description

Technical Field

[0001] The utility model relates to the field of rapid prototyping foam moulds, in particular to a rapid prototyping foam mould. Background Art

[0002] Plastic foaming molds are commonly known as foam molds. Foam molds are made by directly filling foaming resin into the mold of the mold, melting it under heat to form a gas-liquid saturated solution, and forming a large number of tiny bubble nuclei through nucleation. The bubble nuclei grow to make foam plastic, and then the foam of the model is compression molded by a pressure roller.

[0003] At present, when the foam mold is used for injection molding, the foam material is mostly poured into a modeler for molding. In this way, the foam material is not subjected to compression molding during molding, and the foam material needs to be slowly cooled before being taken out, which makes it inconvenient to mold it quickly. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a foam mold that can be quickly molded, so as to solve the problem raised in the above background technology that at present, when injecting foam molds, most of them are formed by pouring foam materials into a model machine, so that during molding, the foam materials are not subjected to compression molding treatment, and it is necessary to wait for the foam materials to slowly cool down before taking them out, which makes it inconvenient to quickly mold them.

[0005] To achieve the above-mentioned purpose, the utility model proposes a foam mold that can be quickly molded, including a mold box, upper mold plates are fixedly arranged on the inner walls of both sides of the mold box, and a pressing roller is fixedly arranged on the bottom of the upper mold plate;

[0006] The mold box is provided with a molding mechanism inside, and the molding mechanism includes a cylinder, a piston rod, a lower template, and a molder. The inner walls on both sides of the mold box are slidably connected with the lower template, and the inner wall of the lower template is slidably provided with a molder. Two cylinders are fixedly installed on the bottom inner wall of the mold box, and the output shafts of the two cylinders are fixedly installed with piston rods fixed to the lower template.

[0007] An electric push rod is fixedly installed on the inner wall of the bottom of the mold box, and a supporting circular plate fixed to the modeler is fixedly installed on the output shaft of the electric push rod.

[0008] In one example, both inner walls of the mold box are provided with limiting grooves, and the inner walls of the two limiting grooves are slidably connected to limiting plates.

[0009] In one example, a sealing baffle is fixedly installed on one side of the two limit plates close to each other, and the sealing baffle is interlaced and connected with the pressure roller.

[0010] In one example, two installation grooves are provided at the bottom of the upper template, and springs are fixedly installed at the tops of the inner walls of the two installation grooves.

[0011] In one example, one end of the two springs away from the mounting groove is fixedly connected to the sealing baffle.

[0012] In one example, a sealed box door is hinged on one side of the front face of the mold box, and a door handle is fixedly installed on one side of the front face of the sealed box door.

[0013] The rapid prototyping foam mold proposed by the utility model can bring the following beneficial effects:

[0014] 1. This foam mold that can be quickly formed can drive the lower template to move upward through the piston rod by starting the cylinder, and drive the modeler and the pressing roller to press the film. When the foam material in the modeler contacts the pressing roller, it continues to move upward, and the foam material on its inner wall is pressed, so that the foam material in the modeler can be quickly formed, reducing time cost.

[0015] 2. The foam mold that can be quickly formed can push the model upward through the circular plate by starting the electric push rod, and separate the model from the lower template to prevent the model from being fixed to the lower template, which makes it inconvenient to take out the mold that has been pressed. Therefore, the model can be taken out, and the mold after pressing inside it can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0024] like Figure 1 to Figure 5 As shown, the embodiment of the utility model provides a foam mold that can be quickly molded, including a mold box 1, an upper mold plate 9 is fixedly provided on the inner walls of both sides of the mold box 1, and a pressing roller 8 is fixedly provided on the bottom of the upper mold plate 9;

[0025] The mold box 1 is provided with a molding mechanism inside, and the molding mechanism includes a cylinder 3, a piston rod 4, a lower mold plate 5, and a molder 6. The inner walls on both sides of the mold box 1 are slidably connected with the lower mold plate 5, and the inner wall of the lower mold plate 5 is slidably provided with a molder 6. Two cylinders 3 are fixedly installed on the inner wall of the bottom of the mold box 1, and the output shafts of the two cylinders 3 are fixedly installed with piston rods 4 fixed to the lower mold plate 5;

[0026] An electric push rod 15 is fixedly mounted on the inner wall of the bottom of the mold box 1 , and a supporting circular plate 14 fixed to the model device 6 is fixedly mounted on the output shaft of the electric push rod 15 .

[0027] Specifically, both inner walls of the mold box 1 have limit grooves 13 , and the inner walls of the two limit grooves 13 are slidably connected to the limit plates 12 . The limit grooves 13 limit the limit plates 12 , and the limit plates 12 fix the sealing baffle 7 .

[0028] Specifically, a sealing baffle 7 is fixedly installed on the side where the two limit plates 12 are close to each other. The sealing baffle 7 is interlaced with the pressure roller 8. The sealing baffle 7 is used to block the model 6 when the film is formed, and the pressure roller 8 performs a film forming effect on the foam material in the model 6.

[0029] Specifically, two installation grooves 10 are provided at the bottom of the upper template 9 , and springs 11 are fixedly installed on the top of the inner walls of the two installation grooves 10 . The springs 11 are fixed by the installation grooves 10 , and the springs 11 return the sealing baffle 7 .

[0030] Specifically, one end of the two springs 11 away from the mounting groove 10 is fixedly connected to the sealing baffle 7 , and the sealing baffle 7 is connected and driven to return through the springs 11 .

[0031] Specifically, a sealed box door 2 is hinged on the front side of the mold box 1, and a door handle 16 is fixedly installed on the front side of the sealed box door 2. The sealed box door 2 is fixed by the mold box 1, the mold box 1 is sealed by the sealed box door 2, and the door handle 16 is fixed, and the door handle 16 facilitates the opening of the sealed box door 2.

[0032] Working principle: Pull the door handle 16 to open the sealed box door 2. At this time, pour the foam material into the model 6 and then start the cylinder 3 to drive the lower template 5 to move upward through the piston rod 4, and drive the model 6 and the pressure roller 8 to perform compression molding. When the model 6 moves upward to fit with the sealing baffle 7, continuing to move upward will drive the sealing baffle 7 to move upward, and squeeze the spring 11. When the sealing baffle 7 fits with the upper template 9, the pressure roller 8 completes the compression molding of the foam material inside the model 6. After molding, the cylinder 3 drives the lower template 5 to return. At this time, the sealing baffle 7 moves downward under the action of the spring potential 11, and the model 6 is separated from the pressure roller 8. With the closing of the cylinder 3, the model 6 and the lower template 5 return to the initial position. At this time, starting the electric push rod 15 can push the model 6 upward through the circular plate 14, and the mold of the model 6 is taken out. Therefore, the utility model can quickly extrude the mold and take out the mold after molding.
