Description

Technical Field

[0001] This utility model relates to die casting machine technology, specifically a positioning structure for die casting machine mold opening. Background Technology

[0002] Die casting machines are machines used for pressure casting. Their working principle is to cool and solidify molten metal in a mold. Die casting machines are equipped with a positioning structure consisting of guide pillars and guide sleeves to limit the movement path of the moving mold base and prevent misalignment between the moving mold base and the fixed mold base, thereby avoiding uneven load distribution of the equipment caused by misalignment between the moving mold and the fixed mold.

[0003] The existing positioning structure can only limit the movement mold base and the fixed mold base. The movement mold and the fixed mold are manually and detachably installed on the movement mold base and the fixed mold base respectively. However, the installation accuracy of the mold cannot be guaranteed when the mold is installed manually. Moreover, the movement mold and the fixed mold itself do not have a positioning structure. Therefore, the existing positioning structure cannot guarantee that the movement mold and the fixed mold can be perfectly aligned. Utility Model Content

The two templates are respectively installed on the moving mold base and the fixed mold base. A moving mold or a fixed mold is fixed on each of the two templates. The moving mold and the fixed mold cooperate with each other. Through holes are provided on both sides of the top of the templates, and limiting grooves are provided on both sides of the bottom of the templates. The openings of the limiting grooves are set downwards. Guide rods are passed through the limiting grooves and through holes. One end of the guide rod is fixed to the fixed mold base, and the other end of the guide rod passes through the moving mold base.

[0006] Preferably, the bottom opening of the limiting groove is funnel-shaped.

[0007] Preferably, both sides of the template are provided with fixing plates, which are fixed to the moving mold base or the fixed mold base by fastening bolts.

[0008] Preferably, the guide rod has a threaded portion at one end facing the fixed mold base, and the fixed mold base has a threaded hole, with the threaded portion threadedly engaging with the threaded hole.

[0022] like Figure 1As shown in Figure 2, a positioning structure for mold opening in a die-casting machine is provided in the die-casting machine. The die-casting machine is provided with a moving mold 10 seat 7 and a fixed mold 11 seat 4, including two templates 8. The two templates 8 are respectively provided in the moving mold 10 seat 7 and the fixed mold 11 seat 4. The moving mold 10 or the fixed mold 11 is fixed on the two templates 8 respectively. The moving mold 10 and the fixed mold 11 cooperate with each other. The top two sides of the template 8 are provided with through holes 14, and the bottom two sides of the template 8 are provided with limiting grooves 13. The limiting grooves 13 are set with their openings facing downwards. Guide rods 9 are passed through the limiting grooves 13 and the through holes 14. One end of the guide rod 9 is fixed to the fixed mold 11 seat 4, and the other end of the guide rod 9 passes through the moving mold 10 seat 7.

[0023] When installing the moving mold 10 and the fixed mold 11, first screw in the two guide rods 9 located at the bottom. The guide rods 9 pass through the moving mold 10 seat 7 and are fixed to the fixed mold 11 seat 4. Then, insert the template 8. Through the limitation of the limiting groove 13, the guide rods 9 support the template 8, the moving mold 10 and the fixed mold 11, which facilitates the installation of the moving mold 10 and the fixed mold 11. Next, insert the two guide rods 9 located at the top. The guide rods 9 pass through the moving mold 10 seat 7 and the two templates 8 in sequence and are fixed to the fixed mold 11 seat 4. Then, push the two templates 8 close to the moving mold 10 seat 7 and the fixed mold 11 seat 4 and fix them by the fixing plate 12 and the fastening bolts.

[0024] The positioning structure for die-casting machine mold opening in this embodiment uses a guide rod 9 passing through the template 8 to limit the moving mold 10 and the fixed mold 11, improve the mold closing accuracy of the moving mold 10 and the fixed mold 11, and ensure that the moving mold 10 and the fixed mold 11 can be completely aligned. In addition, a limiting groove 13 is provided at the bottom of the template 8 to facilitate the installation of the template 8 and ensure the installation accuracy of the moving mold 10 and the fixed mold 11.

[0026] Both sides of the template 8 are provided with fixing plates 12, which are fixed to the moving mold 10 seat 7 or the fixed mold 11 seat 4 by fastening bolts.

[0027] The guide rod 9 has a threaded part at one end facing the fixed mold 11 seat 4, and the fixed mold 11 seat 4 has a threaded hole, with the threaded part threaded into the threaded hole.

[0028] The die-casting machine includes a base 1, a fixed mold 11 seat 4 disposed at one end of the base 1, a mounting seat 2 disposed at one end of the base 1 relative to the fixed mold 11 seat 4, a moving mold 10 seat 7 disposed between the fixed mold 11 seat 4 and the mounting seat 2, guide posts 6 disposed around the mounting seat 2, the two ends of the guide posts 6 being fixed to the mounting seat 2 and the fixed mold 11 seat 4 respectively, the guide posts 6 passing through the moving mold 10 seat 7, the fixed mold 11 seat 4 being provided with a liquid injection assembly 5, the mounting seat 2 being provided with a hydraulic cylinder 3, the piston rod of the hydraulic cylinder passing through the mounting seat 2 and being fixedly connected to the moving mold 10 seat 7, and the liquid injection assembly 5 communicating with the fixed mold 11.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
