Description

Technical Field

[0001] The utility model relates to the field of molds, and particularly relates to a test mold device for hot-melt road marking paint. Background Art

[0002] Hot-melt road markings are a widely used form of road markings, which have the advantages of fast construction, strong wear resistance, and relatively low cost. The hot-melt marking paint is in the form of solid powder at room temperature, and is melted into a liquid state during construction, and then cooled and solidified on the road surface to form a durable marking. This kind of marking usually contains reflective glass beads to improve visibility at night and in bad weather conditions.

[0003] To ensure the construction quality of road markings, before formal construction, it is necessary to conduct indoor tests on the raw material hot-melt road marking paint used, and the main test indicators include density, softening point, compressive strength, non-stick tire drying time, and fluidity, etc.

[0004] Among them, when testing the density and compressive strength indexes of the test hot-melt marking paint, it is necessary to prepare three cube specimens of 20mm×20mm×20mm. The structure of the sample maker recommended by the current specification is relatively complex. Four fixing screws are required to form one specimen at a time, and only one sample can be formed by one mold, resulting in low test efficiency. When demolding, it is necessary to loosen four fixing screws and other cumbersome operations, which easily cause the formed specimen to have the phenomenon of corner chipping. In addition, the fixing screws are prone to slipping after long-term use, affecting the sample accuracy and test accuracy. Summary of the Utility Model

[0030] To make the objectives, technical solutions and advantages of the utility model more clear, the utility model will be further described in detail below with reference to the accompanying drawings. It should be noted that the directional terms such as "upper", "lower", "left", "right", "front", "rear", "inner" and "outer" that appear or will appear in the text of the utility model are only based on the drawings of the utility model, and they do not specifically limit the utility model.

[0031] Refer to Figures 1-5 , the utility model discloses a test mold device for hot-melt marking paint, which includes a base 1, a magnetic attraction mechanism 2 and a mold assembly. The magnetic attraction mechanism 2 is installed in the base 1, and the mold assembly is detachably connected to the base 1 through the magnetic attraction mechanism 2.

[0032] The mold assembly includes a first mold part 3 and a second mold part 4. Both the first mold part 3 and the second mold part 4 are made of magnetic materials; the first mold part 3 and the second mold part 4 can be magnetically connected to the magnetic attraction mechanism 2 respectively, so that the first mold part 3 and the second mold part 4 can be fixed on the base 1; a sample preparation cavity 5 for carrying samples is formed among the first mold part 3, the second mold part 1 and the base 1.

[0033] The test die device for hot-melt marking paint of the utility model utilizes the magnetic attraction characteristics of the magnetic attraction mechanism and the die assembly. When the switch on the magnetic attraction mechanism is turned on, the first die part and the second die part are quickly adsorbed and fixed on the base. When the switch on the magnetic attraction mechanism is turned off, the first die part and the second die part are quickly separated from the base. This separable disassembly and assembly method saves disassembly and assembly time compared with the existing method of screwing, is simple to disassemble and assemble, improves the test efficiency, reduces the labor intensity, and also avoids the phenomenon of corner breakage during demolding. In addition, it also avoids screw thread slipping, improving the sample accuracy and test accuracy.

[0034] It should be noted that the magnetic attraction mechanism 2 is provided with a magnetic attraction switch, and the magnetic attraction switch is arranged outside the base 1. When the user turns on the magnetic attraction switch, the die assembly and the magnetic attraction mechanism are magnetically connected, so that the die assembly is fixed on the base. When the user turns off the magnetic attraction switch, that is, the magnetic attraction force between the die assembly and the magnetic attraction mechanism is turned off, so that the die assembly can be separated from the base, thus realizing the disassembly and assembly of the die device. The magnetic attraction mechanism 2 can adopt the existing technical structure and will not be introduced in detail here.

[0035] Preferably, the magnetic material is iron, but not limited thereto.

[0036] Among them, the first die part 3 and the second die part 4 are spliced to facilitate the formation of a sample-making cavity.

[0037] Specifically, as Figure 1 、 4 shown, the first die part 3 includes a first connecting strip 31 and first enclosing strips 32 respectively arranged at both ends of the first connecting strip 31, and the second die part 4 includes a second connecting strip 41 and second enclosing strips 42 respectively arranged at both ends of the second connecting strip 41; the first connecting strip 31 and the second connecting strip 41 are snap-connected, and the first enclosing strip 32 and the second enclosing strip 42 are abutted; a sample-making cavity 5 is formed between the first connecting strip 31, the first enclosing strip 32, the second connecting strip 41, the second enclosing strip 42 and the base 1. The splicing method of the first die part and the second die part by snap connection and abutment makes the structure of the die assembly reliable and compact, and the bottom wall of the base serves as the bottom surface to form the sample-making cavity. This connection method reduces the number of die accessories, which is convenient for management. It also reduces the screw slipping caused by long-term use, improves the die accuracy, and thus improves the sample accuracy and test accuracy.

[0038] More specifically, the first gaskets 32 are arranged in parallel and are respectively perpendicularly connected to the first connecting strip 31; the second gaskets 42 are arranged in parallel and are respectively perpendicularly connected to the second connecting strip 41. That is, the first module 3 and the second module 4 are in an "I" shape, and after being spliced, they form a "field" character structure, that is, there are four product cavities, enabling a mold to form four samples at one time. Compared with the existing mold that can only form one sample at one time, the utility model greatly improves the efficiency of single preparation, and the working efficiency is increased by 4 times, with high test efficiency.

[0039] Among them, the first connecting strip 31 and the second connecting strip 41 cross and overlap, and both ends of one second gasket 42 are respectively abutted against two first gaskets 32 to form the inner side wall of the closed sample preparation cavity.

[0040] Preferably, as Figures 2-3 shown, a first card interface 311 is provided at the top of the first connecting strip 31, and a second card interface 411 is provided at the bottom of the second connecting strip 41. The first connecting strip 31 and the second connecting strip 41 are snap-connected through the first card interface 311 and the second card interface 411. Through the settings of the first card interface and the second card interface, the first connecting strip and the second connecting strip can overlap and be placed on the same plane, making the inner wall of the enclosed product cavity complete and leak-free. Among them, the width d1 of the first card interface 311 is equal to the width of the second connecting strip, and the width d2 of the second card interface 411 is equal to the width of the first connecting strip.

[0041] Preferably, the cross-sectional shape and size of the base 1 are adapted to those of the mold assembly.

[0042] Preferably, the cross-sectional shape of the base 1 is square or rectangular. More preferably, the cross-sectional shape of the base 1 is square.

[0043] Preferably, the length of the second gasket 42 is equal to the length of the first connecting strip 31; the length of the first gasket 32 is equal to the sum of the length of the second connecting strip 41 and the width of the second gasket 42, ensuring the flatness of the four sides of the mold assembly, the maximization of the volume of the sample preparation cavity, and the sealing of the sample preparation cavity.

[0044] In order to make the mold assembly have balanced force and be not easily movable, preferably, as Figure 4 shown, the magnetic attraction mechanism 2 is respectively arranged corresponding to the first gasket 32 and the second gasket 42. Two first gaskets 32 and two second gaskets 42 are respectively arranged on the four sides of the base 1. In order to make the first module and the second module have balanced force and be not easily movable, magnetic attraction mechanisms are provided on the four sides of the base. Under the action of magnetic attraction, the first gasket and the second gasket are fixed on the four sides of the base, so that the first module and the second module are fixed on the base and the fixed connection structure is stable and reliable.

[0045] In order to further ensure that the first mold and the second mold do not move horizontally, preferably, the mold assembly further includes a positioning rod (not shown in the figure).

[0046] like Figure 1 、 4 As shown in FIG. 5 , the first module 3 is provided with a first positioning hole 6, and the base 1 is provided with a second positioning hole 11 corresponding to the first positioning hole 6. The positioning rods are respectively inserted through the first positioning hole 6 and the second positioning hole 11. The axis of the positioning hole is perpendicular to the plane of the base, that is, the positioning rod is perpendicular to the plane of the base. The positioning rods prevent horizontal displacement of the mold assembly under the limiting action of the positioning rods. It should be noted that the first positioning hole 6 extends through the upper and lower end surfaces of the first module 3 or the second module 4.

[0047] Therefore, the mold assembly is subjected to a vertical downward force from the magnetic attraction mechanism, and a horizontal force from the positioning rod. These two forces secure the mold assembly to the base. To disassemble, simply close the magnetic attraction mechanism and pull out the positioning rod to separate the mold assembly from the base. This simple structure makes assembly and disassembly easy and efficient.

[0048] Preferably, if Figure 5 As shown, the second positioning holes 11 are respectively provided at the corners and the center of the base 1. That is, the number of the second positioning holes 11 is 5, which are respectively distributed at the four corners and the center of the base 1, so that the mold assembly is subjected to balanced forces.

[0049] Accordingly, if Figure 1 、 4 As shown, first positioning holes 6 are provided at both ends of the first surrounding strip 32, a first positioning hole 6 is provided at the center of the first connecting strip 31, and a first positioning hole 6 is provided at the center of the second connecting strip 41. Specifically, the first positioning hole 6 of the first connecting strip 31 is provided at a position corresponding to the first card interface 311, and the first positioning hole 6 of the second connecting strip 41 is provided at a position corresponding to the second card interface 411. The first positioning holes 6 of the first connecting strip 31 and the second connecting strip 41 are provided in correspondence. Therefore, the positioning rod at the center of the mold device is respectively provided through the first positioning hole 6 of the first connecting strip 31, the first positioning hole 6 of the second connecting strip 41, and the second positioning hole 11 at the center of the base 1. This positioning rod serves to position the first module, the second module, and the base.

[0050] More preferably, the positioning rod is interference-fitted with the first positioning hole 6 and the second positioning hole 11 respectively.

[0051] In summary, the utility model provides a thermoplastic road marking paint test mold device, which is easy to assemble and disassemble and has high test efficiency.

[0052] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
