Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts manufacturing technology, and in particular relates to a molding die structure for automotive wire groove clips. Background Technology
[0002] Existing injection molds consist of two parts: a moving mold and a fixed mold. The moving mold is installed on the moving platen of the injection molding machine, and the fixed mold is installed on the fixed platen of the injection molding machine. During injection molding, the moving mold and the fixed mold close to form a gating system and a cavity. When the mold is opened, the moving mold and the fixed mold separate to remove the plastic product.
[0003] Currently, many companies face challenges in manufacturing automotive wire groove tongue-coating injection molds. Due to unreasonable mold structure design, high temperature at the tongue root, and slow heat dissipation, the molds deform after cooling due to shrinkage, resulting in inconsistent product quality. Furthermore, existing molds are prone to air entrapment, often requiring subsequent mold repair and adjustments, which increases cost pressure.
[0004] Therefore, it is necessary to provide a mold structure with a split structure and venting grooves. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a molding die structure for automotive wire groove clips.
[0006] To solve the above problems, the present invention adopts the following technical solution: A molding die structure for a vehicle wire groove latch includes a wire groove latch insert. The insert is integrally formed, with its upper half being a fixing plate and its lower half being the main body. The fixing plate is designed with positioning bosses, locking grooves, and several auxiliary surfaces to assist in the forming of the wire groove latch. The outer wall of the main body is designed and formed with a recessed venting groove structure. There are two venting grooves: a first venting groove extends circumferentially along the main body, and a second venting groove extends axially along the main body, with the first and second venting grooves connected. The overall size of the fixing plate is 5% to 15% larger than the standard size of the wire groove latch.
[0007] Preferably, a water channel can be provided at the bottom of the main body to assist in heat dissipation.
[0008] Beneficial effects of this utility model Compared with existing technologies, the advantages of this utility model are: When the grooved tongue cools, it deforms due to thermal expansion and contraction. Therefore, this invention solves the shrinkage problem after cooling by increasing the overall size of the fixing plate, i.e., pre-deformation design. This can offset the shrinkage deformation during the subsequent cooling process of the grooved tongue and ensure that the cooled tongue meets product quality requirements. In addition, through detailed design, this invention forms an effective and unobstructed venting groove after being inserted into the outer insert or mold core. Specifically, it has a first venting groove and a second venting groove that are connected to each other. This guides the gas generated at the fixing plate to be discharged during the molding process, and then discharges the gas inside the mold through the venting groove. This design improves the venting performance of the mold and ensures the production efficiency and quality of the mold. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model.
[0010] Figure 2 This is a partially enlarged structural schematic diagram of the present invention. Detailed Implementation
[0011] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.
[0012] like Figures 1 to 2 As shown, the present invention discloses a molding die structure for a vehicle wire groove latch, including a wire groove latch insert (10). The wire groove latch insert (10) is integrally formed, with the upper part being a fixing plate (1) and the lower part being a main body (2). The fixing plate (1) is designed with a positioning boss (12), a locking groove (11), and several auxiliary surfaces to assist in the forming of the wire groove latch. The outer wall of the main body (2) is designed and formed with a recessed exhaust groove. There are two exhaust grooves. The first exhaust groove (20) extends along the circumference of the main body (2), and the second exhaust groove (21) extends along the axial direction of the main body (2). The first exhaust groove (20) and the second exhaust groove (21) are connected. The overall size of the fixing plate (1) is 5% to 15% larger than the standard size of the wire groove latch.
[0013] The above technical solution can achieve the following: when the groove tongue is cooled, it will deform due to thermal expansion and contraction. Therefore, this utility model solves the shrinkage problem after cooling by increasing the overall size of the fixing plate (1), that is, the pre-deformation design, so as to offset the shrinkage deformation during the subsequent cooling process of the groove tongue and make the cooled tongue meet the product quality requirements.
[0014] It is also worth mentioning that this utility model, through detailed design, forms an effective and unobstructed venting groove after being inserted into the outer insert or mold core. Specifically, it consists of a first venting groove (20) and a second venting groove (21) that are connected to each other. This guides the gas generated at the fixed plate (1) during production molding and discharges the gas inside the mold through the venting groove. This design improves the venting performance of the mold and ensures the production efficiency and quality of the mold. Another design that works in conjunction with this to increase the mold's lifespan is that a water channel can be opened at the bottom of the main body (2) to assist in heat dissipation, which is beneficial for heat dissipation during and after the mold is working and after the groove tongue is formed.
[0015] The molding die structure for automotive wire groove clips developed using the above solution has the following advantages: 1. The insert can adjust the processing dimensions in advance according to the deformation direction of the product, i.e., pre-deformation design, thereby improving the deformation problem of the product after thermal expansion and contraction; 2. The main body (2) is designed and formed with exhaust grooves, which can improve the trapped air during product production and assist in heat dissipation to a certain extent; 3. The design has been changed from a single integrated structure for inserts and mold cores to a separate structure. This structure makes disassembly easier, processing simpler, and reduces maintenance costs.
[0016] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
