Description

Technical Field

[0001] The present application relates to the field of seals. Background Art

[0002] When users make wax seal coins, they need wax seal heads for stamping. Wax seal heads currently have many limitations and problems. Wax seal heads are made of metal, which is expensive and expensive. The market generally uses precision engraving machines or laser engraving machines to engrave the patterns on wax seal heads. It takes a long time to process a head, and mass production will result in slow production and high costs. Wax seal heads on the market are limited by production processes and manufacturing costs. For example, metal is not easy to engrave, and it is difficult to engrave sufficiently fine grooves. The depth of the pattern on the head is generally around 0.4mm-1.5mm. If users want to use it to print deeper, more styling, or 3D patterns, there is no way. When users use wax seal heads to stamp, it is easy to stick to the wax seal coins and it is difficult to remove them. Even if an angle is made to facilitate demolding when designing the wax seal head, the same problem will occur.

[0003] The pattern of the metal seal head will have a draft angle when it is produced and designed, so that it can be easily separated from the wax seal coin. The pattern of the metal seal head will have a draft angle when it is produced and designed, so that it can be easily separated from the wax seal coin. However, the draft angle will affect the formation of the pattern. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and disclose a seal head, which is characterized by:

[0005] It is processed and formed from rubber material;

[0006] It includes a groove for pattern forming, and the depth of the groove is at least 2mm;

[0007] The shape of the groove is set so that the molded product cannot be demoulded from the groove along the Z-axis direction, and the Z-axis is a direction perpendicular to the bottom surface of the seal head.

[0008] In a specific embodiment, the opening of the slot has a smaller size than the interior of the slot.

[0009] In another specific embodiment, at least one protrusion is disposed on the surface of the groove.

[0010] In the improved solution, the depth of the groove is 2mm-16mm.

[0011] In the improved solution, the rubber material is food grade silicone.

[0012] In the improved solution, the Shore hardness of the rubber material is 20-90.

[0013] In the improved solution, the wax seal head is provided with a threaded hole fixedly connected to the handle.

[0014] In an improved solution, the sealing wax seal head does not have a draft angle.

[0015] The application also discloses a seal, comprising:

[0016] The sealing wax seal head;

[0017] A handle fixedly connected to the wax seal head.

[0018] In a preferred solution, the handle is detachably connected to the wax seal head via a thread. More specifically, a threaded hole is provided at the upper portion of the wax seal head, and a threaded rod is provided at the handle, and the threaded hole and the threaded rod are fixedly connected.

[0019] Since the present application is made of silicone, the pattern part (slot) of the seal head is already engraved when the silicone mold is made. The silicone itself will have a pattern when it is produced and formed, and no secondary engraving is required. The production time cost is greatly reduced and it can be applied to large-scale production. The seal head of the present application is based on silicone material. Based on the existing production process, it can be made in various colors, and is not limited to the phenomenon that the seal head in the existing wax seal field can only be selected in copper color.

[0020] In a preferred embodiment, a transparent seal head can be made, and the user can directly observe the process of sealing wax forming when stamping, which will greatly increase the user's preference. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1: The present application discloses a wax seal head 10, characterized in that:

[0028] The sealing wax seal head is formed by processing rubber material

[0029] It includes a groove for pattern forming, and the depth of the groove is at least 2mm;

[0030] The opening of the slot has a smaller size than the interior of the slot.

[0031] The sealing wax seal head has no draft angle.

[0032] like Figure 3 and Figure 4 As shown, it can form a plug molded product, which is an example of a slot opening having a smaller size than the inside of the slot, and the molded product 30 is a product that the wax seal head 10 can be molded. Figure 3 As shown, the second slot 13 is in the shape of a truncated cone with a relatively small opening. If the wax seal head 10 is made of a hard material such as metal, normal demoulding will not be possible due to the relatively small opening. However, the present embodiment uses food-grade silicone material, which is elastic in itself and can be demoulded for small slots, making the molded products more abundant. During molding of the present embodiment, if the depth of the seal head is relatively deep, the seal head can be inverted first, and the melted wax liquid can be poured into it; after solidification, the wax liquid can be applied to the pad, and the seal can be stamped for the second time. At this time, the already formed wax will solidify with the wax liquid on the pad (because the wax liquid on the pad has a high temperature, and after contacting the already solidified surface, the wax in contact with the surface will melt and blend together).

[0033] During demoulding in this embodiment, due to the elasticity of the silicone material itself, the small mouth has an expansion effect, which can achieve smooth demoulding in the Z-axis direction. During demoulding, the handle needs to be operated to move the seal head in the Z-axis direction, and the handle can be rotated to assist when necessary.

[0034] In the prior art, since the wax seal heads are usually made of hard metal, in order to facilitate demoulding, the wax seal heads are all equipped with draft angles, so the edge of the pattern will have a problem that the bottom edge area is larger than the top; usually the mouth is large, and the internal pattern is relatively small. At the same time, due to the draft angle, the draft angle will also affect the overall design of the pattern. Since the present application adopts rubber material, and the rubber material has a certain elasticity, the present application does not need to be designed with a draft angle first, which can avoid the influence of the draft angle on the pattern. At the same time, since rubber is elastic, the present invention can be designed with a small mouth shape, that is, the opening of the slot has a smaller size relative to the inside of the slot.

[0035] In a specific implementation scheme, the depth of the groove is 2mm-16mm. Compared with the existing seal heads, the present invention has a greater depth, and can form patterns with some 3D stereoscopic effects or patterns with height, which can be restored when making silicone molds, making the produced wax seal coins more vivid and cute. It is not limited by the traditional engraving process for making seal heads in the past (only very shallow patterns can be made). The designable form has been upgraded from 2D to 3D, which allows the wax seal coins to have more pattern designs, and also allows players in the wax seal field to have more creative design space. The present application also improves the color matching method of the wax seal. The existing wax seal color matching is achieved by stamping wax seal coins of different colors with the same wax seal head, cutting them with a carving knife, and then splicing and assembling them and stamping them again to form wax seal coins with multiple colors. It is relatively simple to use a silicone sealing wax seal head to achieve sealing wax seal color matching. Because the pattern itself is relatively three-dimensional, the groove is relatively deep. Different colors of sealing wax wax can be poured in separately. When all of them are solidified, a base plate can be covered to form a multi-color sealing wax seal.

[0036] The rubber material is food grade silica gel, and the Shore hardness of the rubber material is 20-90.

[0037] The sealing wax seal head is provided with a threaded hole fixedly connected with the handle.

[0038] The application also discloses a wax seal, comprising:

[0039] The sealing wax seal head and a handle fixedly connected to the sealing wax seal head.

[0040] In a preferred embodiment, the handle is detachably connected to the sealing wax seal head via a thread. Specifically, a screw is provided on the handle, the screw has threads, and a threaded hole is provided on the sealing wax seal head. The threaded hole and the screw are cooperatively connected so that the handle can be connected to the sealing wax seal head. When in use, the handle can be held for operation.

[0041] Embodiment 2: The difference of this embodiment is that the shape of the slot is different, such as Figure 2The schematic diagram of Example 2 is shown, the wax seal head 10 includes a first slot 11, the first slot 11 is a triangular prism structure, and a plurality of protrusions 12 are provided on the surface inside the first slot 11, and the protrusions 12 can form recesses on the surface of the molded product, making the product more diverse. If the wax seal head 10 is made of traditional hard materials, the protrusions 12 will make it impossible to demould the product normally. Since the present application uses rubber materials, it has a certain elasticity, so that it can be demoulded normally in the presence of the protrusions 12. In some specific embodiments, the surface of the protrusion 12 is smooth, such as a spherical structure. When demoulding, if the seal head moves along the Z-axis direction, the protrusion 12 and the first slot 11 can be squeezed and deformed, so that it can be demoulded normally in the Z-axis direction. When necessary, the handle can also be turned.
