Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to an injection mold for a rubber part. Background Art

[0002] An injection mold is a tool for producing plastic products. It is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. It mainly achieves the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained.

[0003] After searching, the patent document with the authorization announcement number CN220720165U discloses a rubber part injection mold, and the technical solution adopted is as follows: it includes a bottom plate, a lower mold is fixedly provided on the top surface of the bottom plate, a top plate is slidably provided in the lower mold, a sleeve is fixedly provided on the bottom surface of the top plate, a threaded rod is rotatably connected in the lower mold, and the threaded rod is threadedly inserted in the sleeve, a first bevel gear is fixedly provided on the outer surface of the bottom end of the threaded rod, a rotating rod is rotatably inserted in the lower mold, and a turntable is fixedly provided at one end of the rotating rod. After the injection molding is cooled, the rotating rod drives the second bevel gear to rotate by rotating the turntable, and the first bevel gear and the second bevel gear are meshed, so that the threaded rod rotates in the movable groove and drives the sleeve to rise at the same time, and then the top rod demolds the molded rubber part to avoid manually pulling out the rubber part, causing partial structural damage to the rubber part, resulting in the rubber part being unusable and increasing material waste.

[0004] When the above-mentioned injection mold is used, after injection molding, the rubber parts are often tightly fitted in the inner cavity of the mold, so that when the rubber parts are taken out, there is a certain friction between the rubber parts and the inside of the mold. At the same time, when the above-mentioned injection mold is used, when the rubber parts are ejected, the rubber products may be deformed or damaged during the ejection process due to uneven force. Therefore, in order to facilitate the removal or ejection of the molded products after injection molding, it is necessary to improve the existing injection molds, thereby providing an injection mold different from the prior art to meet the actual use needs, which is very necessary and also has broad promotion value.

[0008] Furthermore, a rubber part injection mold described in the present invention is used, and protective covers are fixedly connected to the outside of the first injection mold and the second injection mold, and cooling pipes are fixedly installed on the outer sides of the first injection mold and the second injection mold; wherein the two cooling pipes are both located inside the corresponding protective covers, and inlet and outlet pipes are fixedly connected at both ends of the two cooling pipes, and the four inlet and outlet pipes extend to the outside of the corresponding protective covers.

[0009] Furthermore, using the rubber part injection mold described in the present invention, two limit grooves are also opened on the top of the processing table, and the two limit grooves are symmetrically distributed on both sides of the sliding groove, and a limit block is fixedly connected on both sides of the first injection mold and the second injection mold, and the four limit blocks are slidably connected in the corresponding limit grooves.

[0011] Furthermore, a rubber part injection mold described in the present invention is adopted, and the injection interface is set to a semicircular columnar structure. Under the action of the driving motor, when the first injection mold and the second injection mold move relative to each other on the processing table with the sliding block, the injection interface at the top of the first injection mold is connected to the semicircular injection interface at the top of the second injection mold, forming a circular columnar injection interface communicating with the injection cavity.

When mold closing and injection molding is required, the first injection mold and the second injection mold can be moved relative to each other. When demolding is required, the first injection mold and the second injection mold can be moved oppositely. In this way, it is convenient to remove the injection-molded rubber parts from the inside of the first injection mold and the second injection mold, so that the rubber parts at this time can be easily demolded.

[0016] Compared with the prior art, the rubber part injection mold of the present invention has the following beneficial effects: since two sliding blocks are provided on the threaded rod, the first injection mold and the second injection mold are respectively connected to the threaded rod through the sliding blocks, and under the action of the driving motor, the two sliding blocks are driven to move axially with the threaded rod through the rotation of the threaded rod, thereby realizing the relative or reverse movement of the first injection mold and the second injection mold on the processing table; in addition, through the cooperation of the sealing strip and the sealing groove, when the first injection mold and the second injection mold move relative to each other, a sealed cavity can be formed when the first injection mold and the second injection mold are molded together, which is useful for injection molding, and when the first injection mold and the second injection mold move in opposite directions, it is convenient to disassemble the rubber part from the inside of the first injection mold and the second injection mold, so that the disassembled rubber part can be easily demolded, and the rubber part can be subjected to uniform force during demolding, thereby avoiding deformation or damage of the rubber product, thereby further improving the demolding quality of the rubber part.
