Sealing strip mould

Abstract

The invention provides a sealing strip mould. The sealing strip mould comprises an upper mould plate and a lower mould plate, the upper mould plate is provided with a plurality of strip-shaped protrusions, the lower mould plate is provided with a plurality of strip-shaped grooves, the strip-shaped protrusions are in one-to-one correspondence with the strip-shaped grooves, the strip-shaped groovesand the strip-shaped protrusions match to form a cavity, the two sides of the strip-shaped grooves are provided with a plurality of positioning protrusions, and the two sides of the strip-shaped protrusions are provided with a plurality of positioning grooves matched with the positioning protrusions. The positioning grooves and the positioning protrusions are in one-to-one correspondence; the twoends of the strip-shaped protrusions are provided with guiding strips, and the two ends of the strip-shaped grooves are provided with guiding grooves penetrating in the thickness direction of the lower mould plate; the guiding grooves and the guiding strips are in one-to-one correspondence; and the guiding strips penetrate through the corresponding guiding grooves and are in clearance fit with theguiding grooves. The sealing strip mould can mold vulcanize a plurality of molded parts at a time, position the upper mould plate and the lower mould plate accurately, avoid the deviation of the molded parts from the correct molding position, and the side walls of the positioning grooves play a role in assisting in sealing, so that the produced product quality is improved.

Description

technical field [0001] The invention relates to the field of molds, in particular to a sealing strip mold. Background technique [0002] The sealing strip for automobile radiator is one of the key components of the radiator. The material is generally EPDM rubber, which mainly plays a sealing role to prevent the leakage of the coolant inside the radiator. The production method of the product generally adopts the flat mold press vulcanization method, and the mold generally adopts the plane structure of the upper and lower molds. Due to the particularity of the product structure, the molded parts are generally linear and long. Due to the large distortion and deformation of the linear molded parts, during the process of vulcanization and production of fillers, it is easy to deviate from the correct molding position when filling, which makes the operation difficult and inefficient. In addition, if the molded part deviates from the correct position, it will easily lead to insuffi...

Problems solved by technology

Due to the particularity of the product structure, the molded parts are generally linear and long. Due to the large distortion and deformation of the linear molded parts, during the process of vulcanization and production of fillers, the filling is easily deviated from the correct molding position, which makes the operation difficult and inefficient.

In addition, if the molded part deviates from the correct position, it will easily lead to insufficient filling, cavitation, and poor product density, which will eventually lead to poor pressure change performance of key indicators of the product and great hidden dangers in quality
