Description
TECHNICAL FIELD
[0001] The utility model relates to the mould technical field that improves water mouth stress, concretely is a mould structure that improves water mouth stress. BACKGROUND
[0002] When manufacturing plastic products such as vehicle light guide plates, the design of the mold has a decisive influence on the quality and performance of the product. In traditional mold design, in order to ensure that the plastic melt can be uniformly filled into the mold cavity, a boss structure is usually designed at the gate of the mold.
[0003] However, this design has encountered special problems in vehicle light guide plate products. Due to the special structural requirements of the light guide plate, the boss design at the gate results in extremely uneven product glue distribution, causing severe stress concentration in the boss area. During the molding process of plastic products, this design causes the combination of inserts and inserts to produce a combination line, which reduces the strength of the product in these areas. This stress concentration can cause cracks during performance and durability testing of the product, thus failing to meet the customer's requirements for product quality.
[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a mold structure for improving water mouth stress. INVENTION CONTENTS

[0008] As a preferred technical scheme, the light guide plate placing area is used to place the light guide plate, the pouring groove is used to pour plastic to form the required product shape, and the integral column insert groove is used to form a boss with the light guide plate to enhance the strength of the gate fitting structure.
[0009] As a preferred technical scheme, the mold is installed in the light guide plate seat, and a positioning structure is arranged between the mold and the light guide plate seat to ensure accurate positioning of the mold on the light guide plate seat.
[0010] As a preferred technical scheme, the pouring groove and the column insert groove are used for one-piece molding of the product, without insert combination line, which increases the strength of the product and makes it less prone to breakage.
[0011] As a preferred technical solution, the mold is made of high-strength material, which can withstand a large injection pressure, ensuring that the mold is not easily deformed or damaged during use.
[0012] Compared with the prior art, the mold structure for improving the water port stress has the beneficial effects that:
[0013] The mold structure for improving the water port stress is provided with a pouring groove, a column insert groove and other structures, so that the plastic melt can be uniformly filled into the mold cavity, avoiding the stress concentration and the joint line problem caused by the boss structure in the traditional mold design. At the same time, the mold made of high-strength material can withstand a large injection pressure, ensuring that the mold is not easily deformed or damaged during use, thereby improving the quality and performance of the product. In addition, the mold structure has the advantages of simple structure, easy manufacturing and installation, and can be widely applied to the production of vehicle-mounted light guide plates and other plastic products, meeting the requirements of customers for product quality.
