Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a split-combination pulp molding mold. Background Technology

[0002] Gashapon blind boxes, also known as capsule toys, typically contain multiple toy models with the same theme, each packaged in a separate gashapon blind box.

[0003] A gashapon blind box is made up of two halves that fit together. One half has a connecting part at its open end, and the other half fits over the connecting part at its open end, thus connecting the two halves.

[0004] Existing molds can only produce half-bodies without connecting structures. Therefore, the half-bodies with connecting parts in existing gashapon blind boxes are usually composed of two overlapping structures, with the inner structure being higher than the outer structure. Thus, the part of the inner structure that is higher than the outer structure forms the connecting part. The overlapping structures are prone to detaching from each other, resulting in a poor user experience. Furthermore, the overlapping part in this structure is redundant, so the materials used are also more expensive from an overall structural perspective, and the processing steps are also increased (the half-bodies with connecting parts are composed of two structures, which need to be molded separately). Therefore, further optimization of the molds is needed. Utility Model Content

[0005] This utility model discloses a split-combination pulp molding die to solve the technical problems of poor performance and numerous processing steps in overlapping capsule toy blind box halves.

[0006] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution:

[0007] A split-type combined pulp molding die includes a punch, a die, and a movable die. The punch, the die, and the movable die are respectively separately arranged. The punch and the die are arranged vertically corresponding to each other, and the movable die is arranged between the punch and the die.

[0008] The punch has a protrusion, and the movable die is used to fit onto the protrusion; the die has a groove, and the groove corresponds to and matches the punch.

[0009] Furthermore, the protrusion is made of silicone.

[0010] Furthermore, the punch is also provided with a support member, which is inserted into the protrusion.

[0011] Furthermore, the support component is made of aluminum alloy.

[0012] Furthermore, the active module has a ring-shaped structure.

[0013] Furthermore, the punch is provided with a positioning groove, the positioning groove is arranged around the protrusion, and the movable die is provided with a positioning end, the positioning end is engaged in the positioning groove so that the movable die is installed on the punch.

[0014] Furthermore, the present invention also includes a capsule toy blind box half, which is used to cover the protrusion.

[0015] Furthermore, the open end of the capsule toy blind box half is provided with a connecting part, and the position of the connecting part corresponds to the position of the movable mold.

[0016] Furthermore, the outer surface of the connecting part is provided with threads or retaining rings, and the inner side of the movable mold is provided with grooves for forming the threads or retaining rings.

[0017] The present invention has the following advantages over the prior art:

[0018] This utility model provides a mold setting with a punch, a die, and a movable mold. First, the punch and die work together to form a half-body of a gashapon blind box without a connecting part. During the secondary forming, the half-body of the gashapon blind box is fitted onto the protruding part, and then the movable mold is fitted onto the main body of the gashapon blind box. When the die is pressed down, the movable mold is pressed under the half-body of the gashapon blind box. The secondary forming forms a connecting part of the half-body of the gashapon blind box between the protruding part and the movable mold, thereby producing an integrally formed half-body of the gashapon blind box. The connecting part and the half-body of the gashapon blind box will not detach, and it saves materials and simplifies the processing technology. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] See Figures 1-8 A modular pulp molding die includes a punch 1, a die 2, and a movable die 3. The punch 1, die 2, and movable die 3 are separately configured. The punch 1 is fixed on a frame. The die 2 is raised and lowered by a drive motor or other drive module. The movable die 3 is set separately and is manually placed between the punch 1 and the die 2 during use. The punch 1 and the die 2 are vertically aligned, and the movable die 3 is positioned between the punch 1 and the die 2. The punch 1 has a protrusion 4, and the movable die 3 is fitted onto the protrusion 4. The die 2 has a groove 5, which corresponds to and matches the punch 1.

[0030] In use, firstly, the concave mold 2 is pressed down and aligned with the convex mold 1, specifically, the groove 5 matches the protrusion 4. The material is formed between the groove 5 and the protrusion 4 to form the capsule blind box half 9. Then, the concave mold 2 is raised, and the movable mold 3 is placed on the capsule blind box half 9 (protrusion 4). The concave mold 2 is pressed down to press the movable mold 3 under the capsule blind box half 9. The material is formed between the movable mold 3 and the protrusion 4 to form the connecting part 10. The connecting part 10 is integrally formed with the capsule blind box half 9, thereby completing the production of the capsule blind box half 9.

[0031] In this embodiment, the protrusion 4 is made of silicone. The silicone protrusion 4 has a certain degree of elasticity and can produce slight deformation. Therefore, during molding, the silicone protrusion 4 can expand outward, which is more conducive to the molding of the gashapon blind box half 9.

[0032] In this embodiment, the punch 1 is further provided with a support member 6, which is inserted into the protrusion 4. The support member 6 serves to reinforce the connection between the protrusion 4 and the punch 1. It should be noted that the support member 6 has a channel for material passage along its axial direction.

[0033] In this embodiment, the support member 6 is made of aluminum alloy.

[0034] In this embodiment, the movable module 3 is a ring structure.

[0035] It should be noted that the cross-sectional shape of the protrusion 4 can be selected in various ways, such as circular, elliptical, polygonal, etc. The protrusion 4 with a circular cross-section is used for the semi-circular capsule blind box half 9, and two semi-circular capsule blind box half 9 are combined to form a circular capsule blind box half 9. The protrusion 4 with an elliptical cross-section is used for the semi-elliptical capsule blind box half 9, and two semi-elliptical capsule blind box half 9 are combined to form an elliptical capsule blind box half 9. The protrusion 4 with a polygonal cross-section is used for the semi-cylindrical capsule blind box half 9, and two semi-cylindrical capsule blind box half 9 are combined to form the main capsule blind box half 9. The shape of the movable mold 3 can also be selected in various ways, depending on the fit of the protrusion 4. For example, when the cross-sectional shape of the protrusion 4 is circular, the movable mold 3 is a ring structure. When the cross-sectional shape of the protrusion 4 is polygonal, the movable mold 3 is a polygonal ring structure.

[0036] In this embodiment, the punch 1 is provided with a positioning groove 7, which surrounds the protrusion 4. The movable mold 3 is provided with a positioning end 8, which is engaged in the positioning groove 7 to mount the movable mold 3 on the punch 1. When the movable mold 3 is fitted onto the capsule toy blind box half 9, the concave mold 2 presses down to press the movable mold 3 onto the punch 1. At this time, the positioning end 8 of the movable mold 3 is inserted into the positioning groove 7 of the punch 1 to perform a positioning function.

[0037] In this embodiment, the present invention also includes a capsule toy blind box half 9, which is used to cover the protrusion 4. This capsule toy blind box half 9 is a product formed through a secondary molding process.

[0038] In this embodiment, the open end of the gashapon blind box half 9 is provided with a connecting part 10, and the position of the connecting part 10 corresponds to the position of the movable mold 3. That is, the connecting part 10 is integrally formed with the gashapon blind box half 9.

[0039] In this embodiment, the outer surface of the connecting part 10 is provided with a thread or a retaining ring 11, and the inner side of the movable mold 3 is provided with a groove 12 for forming the thread or retaining ring 11. The material forms the outer surface thread or retaining ring 11 of the connecting part 10 in the groove 12 of the thread or retaining ring 11. The thread or retaining ring 11 is used to connect with another gashapon blind box half 9.

[0040] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
