Description

[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a mold injection structure. [Background Technology]

[0002] like Figure 1 The product 20 shown has a groove 30. The entire circumference of the product 20 is an external surface, and glue is not allowed to enter. Therefore, when molding the product 20, the glue entry position is set in the groove 30.

[0003] Generally, direct glue injection is used. However, the groove 30 of product 20 has a circular hole structure 40. Therefore, due to the constraint of the circular hole structure 40, the glue inlet must be located at a position that avoids the circular hole structure 40 within the groove 30. Figure 2 As shown, when the gate 50 is placed at any position within the groove 30, the mold core will have a thin wall due to the shape of the groove 30 of the product 20 and the presence of the gate 50. Therefore, during the injection molding of the product 20, the thin wall of the mold core is easily damaged, resulting in leakage of glue and causing defects in the product 20. The corresponding mold core needs to be remade. Furthermore, the thin wall of the mold core prevents it from being mass-produced, thus increasing the production cost of the product 20 and the timeliness of demand.

[0004] Submerged gate is a gate design evolved from point gate. Its runner is located on the parting surface (the contact surface between the moving and stationary molds when the mold is closed). The gate is submerged below the parting surface and enters the mold cavity at an angle. Common methods include... Figure 3 The product 20 is molded by injecting the glue through the submerged gate 60 shown, but there is no space for a runner in the groove 30 of this product 20.

[0005] In view of this, it is necessary to provide a mold injection structure to solve the above problems. [Summary of the Invention]

[0006] The technical problem this invention aims to solve is as follows: When the entire circumference of a product is an external surface where glue cannot be injected, a point-gating method is generally used, with the injection point located within a groove in the product. However, due to the limitations of the circular hole structure within the groove, placing the point gate anywhere within the groove results in a thin-walled mold core due to the groove shape and the provided injection point. This thin-walled section of the mold core is easily damaged during injection molding, leading to glue leakage and product defects. Furthermore, the mold core needs to be remade, increasing production costs. Additionally, when using a direct submarine injection method, there is no space within the product groove to create a runner. Therefore, this invention provides a mold injection structure to solve the above problems.

[0007] The solution to the technical problem of this invention is: a mold injection structure, comprising:

[0008] Insert module, the insert module is detachably connected to the mother mold core, the side of the insert module close to the product is shaped to the groove of the product, and is used to form the groove of the product;

[0009] The runner module is located inside the insert module. The runner module is connected to the runner in the mother mold on the side away from the product. The runner module is provided with a submarine gate module on the side closer to the product. The inlet group of the submarine gate module is located on the side wall inside the product groove.

[0010] Preferably, the insert module includes at least one first insert and at least one second insert. The runner module is provided with a first runner and a second runner according to the number of inserts in the insert module. The first runner is located in the first insert, and the second runner is located in the second insert. The first runner in the first insert and the second runner in the second insert are connected to each other. The submarine gate module includes a first submarine gate and a second submarine gate. The sprue group includes a first sprue and a second sprue. The first submarine gate and the first sprue are located on the first runner side of the first insert, and the second submarine gate and the second sprue are located on the second runner side of the second insert. The purpose is to facilitate the processing of the insert module.

[0011] Preferably, the first flow channel in the first insert and the second flow channel in the second insert are both formed by electrical discharge machining and CNC machining.

[0012] Preferably, the material of the insert module includes, but is not limited to, heat-treated S136.

[0013] The beneficial effects of this invention are that it provides a mold injection structure that employs a detachably connected insert module within the mother mold core. The side of the insert module closest to the product conforms to the groove of the product, forming the groove. The insert module also includes a runner module, with the side of the runner module furthest from the product connecting to the runner within the mother mold core. A submarine gate module is located on the side of the runner module closest to the product, and the injection port assembly of the submarine gate module is positioned on the sidewall within the product groove. This solves the problem of injection when the product groove is restricted by a circular hole structure. [Attached Image Description]
