Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a mold for producing wear-resistant and shock-absorbing treadmill tracks. Background Technology

[0002] Extrusion dies are a type of forming die, and their material discharge is achieved through the extrusion action. They are widely used in the production of various profile structures. For example... Figure 1 As shown, this is a cross-section of a track profile for a wear-resistant and shock-absorbing treadmill. Since the profile 10 has four extended edges 101, and the thickness of the extended edges 101 is greater than the thickness of the main side wall 102, that is, the side walls of the profile 10 have different thicknesses, the surface of the extruded profile 10 will have defects such as surface roughness, dark marks and shadows during the production process using ordinary extrusion molds, which will affect the subsequent processing and manufacturing of the profile 10. Utility Model Content

[0003] The purpose of this invention is to provide a mold for producing wear-resistant and shock-absorbing treadmill tracks, which has the advantage of improving the quality of extruded products.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A mold for producing wear-resistant and shock-absorbing treadmill tracks includes an upper mold and a lower mold. The upper mold and the lower mold are fastened together. A male head on the upper mold is fitted into a forming hole on the lower mold. The male head is located at the center of the bottom end face of the upper mold. The male head has four through-holes around its perimeter, and adjacent through-holes are separated by ribs.

[0006] The lower mold has a welding chamber recessed on its top end face, and the welding chamber has a forming hole that runs vertically through it. Each of the flow holes of the upper mold is connected to the welding chamber.

[0007] The forming hole includes a central hole and four side holes. The central hole is located in the middle of the forming hole and is used to fit the male connector. The four side holes are located around the central hole. The width of the side holes is greater than the distance between the central hole and the adjacent side wall of the male connector.

[0008] Four flow-blocking blocks are protruding from the outer periphery of the forming hole in the welding chamber, and the four flow-blocking blocks are respectively located between each side hole and the side wall of the welding chamber.

[0009] Furthermore, the four side holes are located at the left and right ends of the front and rear sides of the central hole, and extend outward away from the central hole; the diversion holes are distributed around the male head in the front, rear, left and right directions.

[0010] Furthermore, the welding chamber is cross-shaped with four diversion holes corresponding to the front, back, left, and right sides, and has four outer side walls that are far away from the forming holes. Adjacent outer side walls are connected by bent side walls that protrude toward the forming holes. The flow blocking block is located between the bent side walls and each side hole.

[0011] Furthermore, of the four flow-blocking blocks, two are located on the front side of the two side holes spaced apart to the left and right, and two are located on the rear side of the two side holes spaced apart to the left and right; and the adjacent end faces of the flow-blocking blocks spaced apart to the left and right are all inclined surfaces, and the distance between the lower ends of the inclined surfaces spaced apart to the left and right is smaller than the distance between the upper ends.

[0012] Furthermore, the male head sidewall protrudes to form a flange, which is located inside the forming hole.

[0013] Furthermore, the side wall and bottom wall of the welding chamber have a circular arc transition.

[0014] By adopting the above technical solution, compared to the existing structure with only three flow diversion holes, the addition of four flow diversion holes connected to the welding chamber improves the welding effect, allows for full fusion of the metal materials, avoids poor welding, and eliminates shadows. Furthermore, by placing flow-blocking blocks on the outside of the edge holes, the flow velocity of the metal materials at the edge holes can be reduced, ensuring uniform flow velocity throughout the forming holes. This balances the impact of edge holes of different widths on the flow velocity, ensuring a smooth surface without shadows on the formed profile, thus ensuring that the product quality meets requirements.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] like Figures 2 to 5 As shown, a mold for producing wear-resistant and shock-absorbing treadmill tracks in this embodiment includes an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are fastened together, and the male head 11 on the upper mold 1 is fitted into the forming hole 21 on the lower mold 2.

[0023] The male head 11 is provided at the center of the bottom end face of the upper mold 1. The male head 11 has four vertically penetrating diversion holes 12 around its perimeter, and adjacent diversion holes 12 are separated by ribs 13. The top end face of the lower mold 2 is recessed with a welding chamber 22. The welding chamber 22 has vertically penetrating forming holes 21. Each diversion hole 12 of the upper mold 1 is connected to the welding chamber 22. Compared with the existing structure that only has three diversion holes 12, by setting four diversion holes 12 connected to the welding chamber 22, the welding effect can be improved, the metal material can be fully fused, poor welding can be avoided, and shadows can be eliminated.

[0024] The forming hole 21 includes a central hole 211 and four side holes 212. The central hole 211 is located in the middle of the forming hole 21 and is used for the male connector 11 to be fitted. The four side holes 212 are located around the central hole 211. The width of each side hole 212 is greater than the distance between the central hole 211 and the adjacent side wall 111 of the male connector. The forming hole 21 and the male connector 11 are used to form a shape such as... Figure 1 The track profile 10 shown has four extended edges 101 formed by four edge holes 212.

[0025] Four flow-blocking blocks 23 are protruding from the outer periphery of the forming hole 21 in the welding chamber 22. The four flow-blocking blocks 23 are respectively located between each side hole 212 and the side wall 221 of the welding chamber.

[0026] By setting a flow-blocking block 23 on the outside of the edge hole 212, the flow rate of the metal material at the edge hole 212 can be reduced, ensuring that the flow rate is uniform throughout the forming hole 21, thereby balancing the influence of edge holes 212 of different widths on the flow rate, and ensuring that the surface of the formed profile 10 is smooth and without shadows, etc.

[0027] like Figure 3 As shown, in this embodiment, the four side holes 212 are located at the left and right ends of the front and rear sides of the central hole 211, and extend outward away from the central hole 211, thereby forming the track profile 10. The diversion holes 12 are distributed around the male head 11 in the front, rear, left and right directions.

[0028] Of the four flow-blocking blocks 23, two are located on the front side of the two side holes 212 spaced apart to the left and right, and two are located on the rear side of the two side holes 212 spaced apart to the left and right. Furthermore, the adjacent end faces of the flow-blocking blocks 23 spaced apart to the left and right are all inclined surfaces 231, and the distance between the lower ends of the inclined surfaces 231 spaced apart to the left and right is smaller than the distance between the upper ends. The inclined surfaces 231 are provided to facilitate the flow of metal material to the central hole 211.

[0029] In this embodiment, the welding chamber 22 is cross-shaped corresponding to the four flow diversion holes 12 in the front, back, left, and right directions, and has four outer side walls 2211 that are far away from the forming hole 21. Adjacent outer side walls 2211 are connected by bent side walls 2212 that protrude toward the forming hole 21. The flow blocking block 23 is located between the bent side walls 2212 and each side hole 212. The outer side walls 2211 that are far away are provided to expand the welding chamber 22 so that the metal material can be fully fused. The bent side walls 2212 that are close to the forming hole 21 are provided to balance the overall flow rate and pressure in the welding chamber 22.

[0030] In this embodiment, the welding chamber sidewall 221 and the welding chamber bottom wall 222 form a circular arc transition. This is to increase the metal flow rate and balance the influence of the corner on the metal flow rate.

[0031] like Figure 5 As shown, in this embodiment, the male head sidewall 111 protrudes outward to form a flange 112, which is located inside the forming hole 21. This flange 112 is used to reduce wear on the male head 11 and improve the service life of the mold.
