Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold technology, and more specifically, it relates to a high-pore vulcanization mold structure of a new type of material. Background Technology
[0002] High-fidelity vulcanizing molds are specialized molds used in the vulcanization process of rubber products. The mold has a parting surface gap for venting. When the mold is closed, the rubber material fills into the mold cavity, and the gas in the cavity is expelled through the parting surface gap. The parting surface gap needs to be adjusted according to the rubber material to avoid excessive gaps that could cause the rubber material to flow out and produce flash. However, vulcanizing molds have a serious problem of trapped air. Trapped air not only causes defects such as air holes and insufficient rubber in the product, resulting in a high scrap rate, but also prolongs the production cycle, increases energy consumption, and significantly increases production costs. Utility Model Content
[0003] This disclosure relates to a novel high-pore vulcanization mold structure to address the serious air-sealing problem in vulcanization molds mentioned in the background art. Air-sealing not only leads to defects such as air holes and insufficient glue in the product, resulting in a high scrap rate, but also prolongs the production cycle, increases energy consumption, and significantly increases production costs.
[0004] This utility model discloses a novel high-pore vulcanization mold structure for a new material, achieved through the following specific technical means:
[0005] This utility model provides a novel high-pore vulcanizing mold structure, comprising: a vulcanizing mold base, the vulcanizing mold base being rectangular in shape; the vulcanizing mold base further comprising: two connecting side seats, the connecting side seats being symmetrically fixedly installed at the left and right ends of the vulcanizing mold base; and two fixing side seats, the fixing side seats being symmetrically fixedly installed at the upper and lower ends of the vulcanizing mold base.
[0006] As a preferred embodiment of this utility model, the vulcanizing mold base further includes: a vulcanizing mold body, which is fixed to the top of the vulcanizing mold base; and cavities, the number of which is set to eight, which are opened on the top of the vulcanizing mold body.
[0007] As a preferred embodiment of this utility model, the vulcanizing mold base further includes a feeding groove, which is located on the top of the vulcanizing mold body.
[0008] As a preferred embodiment of this utility model, the vulcanizing mold base further includes: an exhaust groove, which is formed in a ring shape on the top of the vulcanizing mold base.
[0009] As a preferred embodiment of this utility model, the vulcanizing mold base further includes: a connecting air groove, which is formed on the top of the vulcanizing mold base; the connecting air groove is connected and communicates with the cavity and the venting groove.
[0010] As a preferred embodiment of this utility model, the vulcanizing mold base further includes: positioning holes, the number of which is set to four, and the positioning holes are symmetrically opened on the top of the vulcanizing mold body; and sealing grooves, the sealing grooves being opened on the top of the vulcanizing mold body.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the actual use of vulcanizing molds, in order to effectively improve the quality and performance of vulcanized products, venting grooves are opened on the vulcanizing mold body to address the problem of trapped air that may occur during the vulcanization process. This ensures that trapped air can be guided out to the maximum extent. At the same time, sealing grooves are opened on the vulcanizing mold body to ensure good sealing at the connection points and prevent air leakage during the vacuuming process. This ensures the effective operation of the vacuum system. Through this connection method, the venting grooves become an important channel for air to be discharged from the mold cavity, which can guide the trapped air in the mold cavity to the vacuum system in a timely and efficient manner.
