Description

Technical Field

[0001] The utility model relates to a mold, more specifically, to a rain boot mold. Background Art

[0002] Rain boots are a common type of footwear in everyday life. Their primary function is to be waterproof and non-slip. Unlike ordinary shoes, rain boots are often produced directly through injection molding. However, due to their different shape, the injection molds used for rain boots are also different. This means that the molds for rain boots require different closing and releasing methods than those for ordinary shoe molds.

[0003] For example, the prior art discloses a horizontal rain boot two-color injection molding machine, with the application number being CN201410216202.X, which records a mold comprising two left and right modules and a middle module. The three are clamped to form an injection cavity, and the corresponding two-color rain boots are formed by injecting materials into the injection cavity in batches.

[0004] However, existing molds have the following disadvantages: 1. They require an external switch to push the module closed and pull the module open. If the external switch fails to work properly, all molds in the entire system will not function properly. 2. The molds are of a single size, and the rain boots produced are all of the same specifications. To produce rain boots of different specifications, corresponding molds must be prepared, which is inflexible and inconvenient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a rain boot mold, which can independently control the opening and closing and can adjust the mold cavity size.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rain boot mold, comprising a mounting base, a central module, a first module, and a second module, wherein the central module is fixedly connected to the mounting base, the first module and the second module are respectively located on either side of the central module, and a synchronization component for driving the first module and the second module to move synchronously is provided on the mounting base;

[0007] The central module includes a mounting rod and a mold block, and the mold block is detachably connected to the mounting rod;

[0008] The first module and the second module both include a mounting plate, a mold plate and a mounting base plate. The mold plate is detachably mounted on the mounting plate. The two mounting base plates are combined to form a mounting hole for the mounting rod to pass through.

[0009] To sum up, the utility model has the following beneficial effects: through the design of the synchronization component, each rain boot mold is independently controlled, and the first module and the second module can be controlled by the synchronization component to move closer to or away from the central module at the same time, thereby meeting the injection molding and mold opening operations after molding.

[0010] And because the mold block and the mounting rod are detachable, and the mold plate and the mounting plate are detachable, the mold block and the mold plate in a single rain boot mold can be replaced to form injection cavities of different sizes, thereby meeting the needs of different sizes.

DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0016] Reference Figures 1 to 3 As shown, in order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rain boot mold, comprising a mounting base 1, a central module 2, a first module 3, and a second module 4, wherein the central module 2 is fixedly connected to the mounting base 1, the first module 3 and the second module 4 are respectively located on both sides of the central module 2, and a synchronization component 5 for driving the first module 3 and the second module 4 to move synchronously is provided on the mounting base 1;

[0017] The central module 2 includes a mounting rod 21 and a mold block 22. The mold block 22 is detachably connected to the mounting rod 21.

[0018] The first module 3 and the second module 4 each include a mounting plate 31 , a mold plate 32 and a mounting base plate 33 . The mold plate 32 is detachably mounted on the mounting plate 31 . The two mounting base plates 33 together form a mounting hole 6 for the mounting rod 21 to pass through.

[0019] The design of the present invention is based on the design of the synchronization component 5. Each rain boot mold is independently controlled, and the first module 3 and the second module 4 can be controlled by the synchronization component 5 to move closer to or away from the central module 2 at the same time, thereby meeting the injection molding and mold opening operations after molding.

[0020] And because the mold block 22 and the mounting rod 21 are detachable, and the mold plate 32 and the mounting plate 31 are detachable, the mold block 22 and the mold plate 32 in a single rain boot mold can be replaced to form injection cavities of different sizes, thereby meeting the needs of different sizes.

[0021] The design of the mounting base plate 33 is such that when the first module 3 and the second module 4 abut against each other, the mounting base plate 33 can be fitted with the mounting rod 21 through the mounting hole 6, and can also be fitted with the mold block 22 through the upper end surface of the mounting base plate 33, thereby enhancing the sealing effect of the injection cavity and preventing material leakage.

[0022] The sealing conditions are divided into the following situations according to the structure of the mold plate 32: 1. A mold groove is provided on the mold plate 32, and the mold groove is provided through the mold plate 32 from top to bottom. In this case, the sealing at the lower end is provided by the mounting base 33;

[0023] 2. The mold groove does not penetrate the mold plate 32 downward. At this time, the seal at the lower end is formed by the abutment of the two mold plates 32. At this time, the purpose of installing the bottom plate 33 is to enhance the sealing effect.

[0024] The advantage of the above situation 1 is that the injection of high-temperature materials will cause the lower end of the plate to be affected by the high temperature, thereby causing concave and convex holes to appear on the lower end of the plate. At this time, the installation base plate 33 can be replaced to ensure the flatness of the injection-molded product port.

[0025] Further preferably, the mounting base plate 33 is detachably mounted on the lower end of the mounting plate 31 , so as to facilitate replacement and maintenance of the mounting base plate 33 .

[0026] The first module 3 further includes a first cover plate 34 and a first motor 35 . The first cover plate 34 is hingedly disposed on the upper end of the corresponding mounting plate 31 . The first motor 35 is used to drive the first cover plate 34 to flip.

[0027] The second module 4 preferably includes a second cover plate 41, a sole plate 42 and a second motor 43. The sole plate 42 is detachably mounted on the second cover plate 41. The second cover plate 41 is hingedly mounted on the upper end of the corresponding mounting plate 31. The second motor 43 is used to drive the second cover plate 41 to flip.

[0028] like Figure 1 As shown, the first cover plate 34 and the second cover plate 41 have different structures, but their functions are similar to those in the prior art, and they are used to form the shoe shaft cavity and the shoe sole cavity, respectively. For example, the first cover plate 34 is first placed on the two mounting plates 31. At this time, the two mounting plates 31, the mounting base plate 33, and the first cover plate 34 together form an injection molding cavity. The shoe shaft is formed by injecting a first color material into the first cover plate 34.

[0029] During the movement, the first cover plate 34 is opened and the second cover plate 41 is covered, and the second color material is injected into the second cover plate 41 to form the sole, thereby forming the two-color rain boots by injection molding.

[0030] Furthermore, the first cover plate 34 and the second cover plate 41 are controlled by the first motor 35 and the second motor 43 respectively. The external controller can control the opening and closing of the first motor 35 and the second motor 43 according to the mold movement position, so as to control the opening and closing of the first cover plate 34 and the second cover plate 41, thereby ensuring the stability of the equipment operation.

[0031] The differences between the first cover plate 34 and the second cover plate 41 are: 1. the depth of the groove; 2. the second cover plate 41 is provided with lines for forming anti-skid shoe lines on the sole; 3. the shape of the groove (shown in the figure).

[0032] The mounting rod 21 is provided with a slot, and the lower end of the mold block 22 is provided with a block. The mold block 22 is connected to the mounting rod 21 via the block, and the engagement of the slot and the block forms a lock (the structure can be provided with through holes in both the block and the mounting rod. When the two through holes correspond, a locking rod and nut pass through and lock. Because this structure is a common snap-fit ​​structure, it is shown in the figure. The through holes are preferably set below the position of the mounting base to prevent material leakage). This structural design can ensure the stability of the orientation of the mold block 22.

[0033] The mounting plate 31 is provided with a mounting groove 7 for mounting the mold plate 32. The mounting groove 7 is set through the mounting plate 31 in the up and down directions. The left and right sides of the mounting groove 7 are both protruded with limit rods 71, and the left and right sides of the mold plate 32 are both provided with limit grooves 8 that cooperate with the limit rods 71.

[0034] A limiting hole 72 is provided on the limiting rod 71 , and a limiting block 81 for blocking the limiting groove 8 is provided on the mold plate 32 . A bolt hole 82 is provided on the limiting block 81 , and the bolt hole 82 is connected to the limiting hole 72 via a limiting bolt.

[0035] like Figure 1 As shown, the mold plate 32 slides downward along the limiting rods 71 ​​on both sides and is connected to the installation groove 7. When it slides into place, the limiting blocks 81 on both sides respectively abut against the limiting rods 71 ​​on both sides. At this time, the limiting holes 72 and the bolt holes 82 are screwed together by limiting bolts, thereby ensuring the stability of the connection and preventing the mold plate 32 from falling out.

[0036] like Figure 1 and Figure 2 As shown, the upper end of the mounting plate 31 is concave to form a groove for placing the limit block 81 and the limit bolt. When the limit bolt is screwed into the bolt hole 82, the upper end of the limit bolt does not exceed the groove setting, thereby ensuring that when the first cover plate 34 or the second cover plate 41 is closed, the upper end surface of the mounting plate 31 is always in a flat state, ensuring the neatness of the first cover plate 34 or the second cover plate 41 when closed.

[0037] The synchronization assembly 5 includes a synchronization motor 51, a synchronization gear 52, a synchronization rack 53 and a synchronization rod 54. The mounting base 1 is provided with a mounting cavity 11. The mounting base 1 is provided with a sliding groove 12 connected to the mounting cavity 11. The synchronization motor 51 is used to drive the synchronization gear 52 to rotate.

[0038] There are two sets of synchronization racks 53 , which are respectively arranged on both sides of the synchronization gear 52 . The synchronization racks 53 are connected to the mounting plate 31 on the same side through a synchronization rod 54 .

[0039] like Figure 3 As shown, the design of this structure is that when the synchronous motor 51 is started, it will drive the synchronous gear 52 to rotate. Since the two synchronous racks 53 are installed on both sides of the synchronous gear 52, when one synchronous rack 53 moves to the left, the other synchronous rack 53 will move to the right, thereby making the synchronous rods 54 approach or move away from each other, achieving the effect of synchronous movement.

[0040] The synchronization rod 54 is arranged in an L-shaped structure. This structure can form a large distance between the sliding groove 12 and the central module 2 to prevent material overflow and affect the synchronization component 5 in the installation cavity 11.

[0041] Preferably, an arc-shaped slope is provided at the upper end of the mounting base 1. The arc-shaped slope is provided between the sliding groove 12 and the mounting rod 21, which can protect the sliding groove 12. When the material overflows onto the mounting base 1, it can be blocked by the arc-shaped slope and cannot flow toward the sliding groove 12 until it solidifies.

[0042] The mounting base 1 is provided with a guide groove, and the mounting plate 31 is provided with a guide portion extending downward, which is slidably connected to the guide groove. The design of this structure plays a guiding role and can ensure the stability of movement.

[0043] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
