Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion die technology, specifically a die with a raised platform on the outside of a small die core to prevent wall deviation. Background Technology
[0002] In many industrial production fields, such as injection molding, die casting, and stamping, molds are widely used to manufacture various parts. At present, in actual operation, the problem of mold core misalignment is quite prominent in traditional molds. In particular, smaller mold cores may be affected by the impact of materials during the blanking process, causing the small mold core to misalign, which in turn affects the wall thickness of the formed aluminum profile and the quality of the finished product.
[0003] In existing technologies, reinforcing beams or bridges are usually set on the small mold core to improve the structural strength of the small mold core and prevent it from swaying due to impact. However, the small mold core in this technical solution is still subject to material compression to some extent, which limits the effectiveness. Utility Model Content
[0004] The main technical problem to be solved by this utility model is to provide a mold with a raised platform on the outside of the small mold core to prevent wall deviation. This mold can prevent the small mold core from deflecting due to material impact and extrusion, thereby enabling stable control of the wall thickness of the molding material.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A mold with a raised platform on the outside of a small mold core to prevent wall deviation includes a detachable upper mold and a lower mold. The upper mold has a feed inlet assembly on the side away from the lower mold, and a mold core assembly on the other side of the upper mold. The mold core assembly includes two first mold cores symmetrically arranged along the center point of the upper mold. Each first mold core has two second mold cores on the side away from each other. A third mold core is symmetrically arranged on the side of the two first mold cores close to each other. Each second mold core has a boss near the feed inlet assembly at its lower part. The boss has an arc-shaped platform structure and its arc surface extends away from the second mold core.
[0007] The following are further optimizations of the above technical solution by this utility model:
[0008] The lower mold has a welding chamber on the side near the upper mold, and the lower mold cavity is located in the middle of the welding chamber.
[0009] Further optimization: The feed port assembly includes a first feed port located in the middle of the upper mold, and a reinforcing beam is provided inside the first feed port.
[0010] Further optimization: The upper mold is equipped with four second feed ports spaced apart from the first feed port. Each second feed port has a third feed port on the side away from the first feed port, and the four third feed ports are arranged symmetrically.
[0011] Further optimization: Each of the first, second, and third feed ports extends through the upper mold to the other side of the upper mold.
[0012] Further optimization: Each of the first, second, and third feed ports is equipped with an inverted bridge at the die head position near the die core assembly.
[0013] Further optimization: A gap is provided between the two first mold cores.
[0014] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. By setting a boss under the small mold core, it prevents the material from impacting the small mold core and causing the small mold core to wobble during the material feeding process. This prevents the wall thickness of the molding die from being affected, improves the quality and yield of the finished product, and is convenient to use.
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] like Figure 1-6As shown: A mold with a raised platform on the outside of a small mold core to prevent wall deviation, comprising a detachable upper mold 1 and a lower mold 2. The upper mold 1 has a feed inlet assembly on the side away from the lower mold 2, and a mold core assembly is provided on the other side of the upper mold 1. The mold core assembly includes two first mold cores 101 symmetrically arranged along the center point of the upper mold 1. Each first mold core 101 has two second mold cores 102 on the side away from each other. A third mold core 103 is symmetrically arranged on the side of the two first mold cores 101 that are close to each other. Each second mold core 102 has a boss 1020 at the position near the feed inlet assembly below it. The boss 1020 has an arc-shaped platform structure and its arc surface extends away from the position of the second mold core 102.
[0024] The lower mold 2 has a welding chamber 201 on the side near the upper mold 1, and a lower mold cavity 202 is formed in the middle of the welding chamber 201.
[0025] The feed port assembly includes a first feed port 104 located in the middle of the upper mold 1, and a reinforcing beam 108 is provided inside the first feed port 104.
[0026] In this embodiment, the reinforcing beam 108 can relieve pressure on the material during feeding to prevent the first mold core 101 from being damaged by the impact force of the material.
[0027] The upper mold 1 has four second feed ports 105 arranged at intervals around the first feed port 104. Each second feed port 105 has a third feed port 106 on the side away from the first feed port 104. The four third feed ports 106 are arranged symmetrically.
[0028] Each of the first feed port 104, the second feed port 105, and the third feed port 106 extends through the upper mold 1 to the other side of the upper mold 1.
[0029] Each of the first feed port 104, the second feed port 105, and the third feed port 106 is provided with an inverted bridge 107 near the die head position of the die core assembly.
[0030] This design, with multiple inverted bridges 107, allows materials to be fully filled into the mold, making it convenient to use.
[0031] A gap is provided between the two first mold cores 101.
[0032] In this embodiment, the gaps between the first mold cores 101 are used to ensure the forming of the aluminum profile mold.
[0033] During use, the material enters the upper mold 1 through the feed port assembly. Under the action of the boss 1020, the material will not directly impact the second mold core 102 during the feeding process, preventing the second mold core 102 from being directly squeezed by the material and causing the second mold core 102 to wobble. This ensures the wall thickness of the formed aluminum profile and improves the yield and quality of the finished product.
[0034] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
