Description

Technical Field

[0001] The utility model relates to the technical field of traffic cone moulds, in particular to a burr-proof and quickly demoulding traffic cone mould. Background Art

[0002] Traffic cone molds are industrial molds specifically designed for manufacturing traffic cones. They are primarily used to shape raw materials (such as plastic and rubber) through injection molding, blow molding, or compression molding. As a common traffic safety device, traffic cones are widely used in various situations, including road construction, temporary parking, and traffic accident scene warnings, to alert drivers and prevent accidents.

[0003] Chinese utility model patent application number CN214266464U discloses a road cone mold, comprising an upper mold, a core block, and a lower mold. The core block is positioned between the upper and lower molds and consists of a core rod and a core holder. A pull rod and a slideway are located at the rear of the upper mold, and the core holder is mounted on the slideway for vertical movement. The lower end of the pull rod extends into the core holder to hold it in place. A spring is attached to the pull rod, with its ends respectively pressing against the upper mold and the core holder. After the upper and lower molds are separated, the core block separates from the upper mold under the combined action of its own weight and the spring, leaving the road cone encased in the core rod free to expand. The upper mold uses the pull rod to hold the core block in place, maintaining a certain distance from the upper and lower molds. The slideway defines the direction of movement of the core block as it separates from the upper mold, and in conjunction with the pull rod, limits the movement of the heavy core block. This also prevents the overhanging end of the core block from swaying and causing the outer end of the core rod to contact the upper or lower molds, thus preventing deformation of the cone tip.

[0004] Existing road cone demolding devices primarily utilize a cover-type demolding method to produce road cones. However, during the mold forming process, various burrs form on the mold surface due to various factors, such as thermal deformation and structural defects within the mold itself. These burrs remain on the cone surface after demolding, affecting its smoothness and subsequent use. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1: Reference Figure 1 - Figure 4 A burr-proof and quickly demoulding road cone mold includes a tripod 1, which is a supporting component of a mold assembly 2, and further includes:

[0028] Mold assembly 2, which is the injection molding site. Mold assembly 2 includes a traffic cone mold 4. The molding chamber 20 formed between the mold 4 and the inner liner 8 is where the cone is formed. An injection tube 5 is attached to one side of the mold 4, where the hot melt adhesive is injected. A frame 6 is installed on one side of the mold 4 to support the main body and the embedded mounting plate 10. Frame 6 is an embedded structure.

[0029] The road cone mold 4 is embedded with an inner shell 8, which is the forming support component of the road cone. One side of the inner shell 8 is provided with a groove 9, which is the location where the insert 12 is embedded and docked.

[0030] The track-type polishing assembly 3 utilizes the structural characteristics of the injection molding device itself to achieve the effect of polishing a rotating body. The track-type polishing assembly 3 includes a slide bar 15 arranged on one side of the frame 6. The slide bar 15 is a component for sliding and positioning the slide plate 14. The slide plate 14 is slidingly provided on the surface of the slide bar 15. The control motor 13 on one side of the slide plate 14 moves left and right, thereby realizing the insertion of the plug 12 inside the embedded groove 9. A motor bracket 19 is provided on one side of the slide plate 14. The motor 13 is provided inside the motor bracket 19. The output end of the motor 13 is provided with an insert block 12. The insert block 12 is embedded and docked inside the embedded groove 9 by magnetic adsorption. The material of the insert block 12 is a magnetic material, and the inner liner 8 is an adsorbable metal material.

[0031] A burr-proof and quickly demoulding road cone mold. The road cone mold 4 is made of high-strength hard material, which can ensure the molding effect of the road cone and prepare for subsequent polishing.

[0032] A burr-proof and quickly demoulding road cone mold, further comprising:

[0033] The anti-leakage component can prevent hot melt glue from leaking during the injection molding process. The anti-leakage component includes a gusset plate 10 that covers the interior of the frame 6 and is used to achieve a docking seal. Handles 11 are provided on both sides of the gusset plate 10, which are the control parts of the gusset plate 10. The gusset plate 10 is embedded in the slot of the frame 6.

[0034] A burr-resistant, quickly demoldable road cone mold features a bearing seat 17 on one side of the slide 14. This seat houses and positions a bearing 18. Bearing 18 is inserted into the interior of bearing seat 17, ensuring the positioning and stable rotation of the main shaft of motor 13. The output shaft of motor 13 is inserted into bearing 18.

[0035] A burr-resistant, quickly demoldable road cone mold. A back plate 16 is provided at the end of a slide bar 15, which acts as a stop for the sliding plate 14. The length between the slide bar 15 and the back plate 16 is determined by allowing the inner container 8 to extend and be demolded, ensuring that the device can be polished and demolded normally.

[0036] A burr-resistant, quickly demoldable road cone mold features a barrier at the top of the injection tube 5 to prevent leakage during hot melt adhesive injection. Braces 7 are installed between the tripods 1 to support them. Braces 7 are welded between the tripods 1.

A corresponding polygonal recess 9 is designed as a recessed, plug-in structure. The insert 12 and recess 9 adhere to each other, ensuring easy disassembly. A forming chamber 20 is located between the inner liner 8 and the road cone mold 4. This chamber is where the cone is cooled and formed.

[0038] Working principle:

[0039] During the actual design process of the present invention, in order to avoid the following technical defects in the prior art: "The prior art road cone demoulding device mainly adopts a cover-type demoulding method to produce the road cone. However, during the molding process of the road cone inside the mold, various burrs are formed on the mold surface due to various reasons such as thermal deformation and structural defects of the mold itself. These burrs will remain on the surface of the road cone after demoulding, affecting the smoothness and subsequent use of the road cone." Therefore, the mold assembly 2 and the track-type polishing assembly 3 are specifically proposed;

[0040] Mold assembly 2: The mold assembly 2 of the present invention improves upon the traditional closed-cover mold. This is mainly because traditional closed-cover molds are prone to burrs and corners at the joints during the demolding process of the road cone, and subsequent polishing by sandpapering or other methods is required, which complicates the process and increases production costs. The road cone mold 4 of the present device is an integrated conical structure. During injection molding, the inner liner 8 is pre-inserted and installed inside the road cone mold 4. The molding chamber 20 reserved between the inner liner 8 and the road cone mold 4 is the molding site of the road cone. Hot melt adhesive is injected into the molding chamber 20 through the injection tube 5, and then cooled to form an integrated mold inside the molding chamber 20. The road cone molded in this way can ensure integrity and avoid the appearance of a large number of burrs. In addition, the molded road cone is attached to the surface of the inner liner 8, which facilitates demolding of the road cone.

[0041] However, even with integrated molding, it is still possible to cause certain burrs on the surface of the road cone. Therefore, we have a slide plate 14 on the surface of the slide rod 15, and the slide plate 14 drives the plug 12 at the end of the motor 13 to be sucked in and inserted into the inside of the embedding groove 9. Start the motor 13, and the motor 13 can drive the inner liner 8 to rotate at high speed inside the road cone mold 4. The road cones attached to the surface of the inner liner 8 will rub against the mold during the rotation process, and the parts with burrs will be polished during the continuous friction process, thereby ensuring the smoothness of the finished road cone. In addition, due to the continuous friction of the road cone during the continuous grinding process, the adsorption force between the road cone and the inner liner 8 will be reduced, which will make it easier to demold later, increasing the practicality of the device.
