[0002] Squeeze casting machines are generally divided into high-pressure casting, low-pressure casting and differential pressure casting, all of which are to fill liquid metal or metal alloy into the mold cavity and squeeze casting through pressurized shrinkage pins. The extruder generally includes a dynamic mold and a static mold. The dynamic mold and the static mold have a cavity respectively, or the cavity is only set on the dynamic mold or the static mold, forming a complete cavity when the mold is closed.

[0003] The patent with application number 202320556515.4 discloses an extrusion molding machine, including a casing body; the top end of the inner wall of the casing body is fixedly connected to an upper mold body through a hydraulic cylinder; the bottom end of the inner wall of the casing body is fixedly connected to a square plate through a column; the top end of the outer wall of the square plate is fixedly connected to a group of round rods through a group of first springs.

[0004] In the above technical solution, when the hollow aluminum rod is formed, the hollow aluminum rod is extruded only through the upper mold body. Since the hollow aluminum rod lacks a positioning mechanism and cannot support the inner wall of the hollow aluminum rod, the hollow aluminum rod is prone to sliding and excessive deformation when extruded, thereby affecting the forming effect of the hollow aluminum rod. Utility Model Content

[0005] The purpose of the utility model is to provide a hollow aluminum rod extrusion forming machine in view of the shortcomings of the prior art. The function of positioning the outer wall and inner wall of the hollow aluminum rod body is achieved through a detachable extrusion die structure in cooperation with a support frame structure fixed on the inner wall of the extrusion die, thereby solving the problem of sliding and excessive deformation of the hollow aluminum rod when it is extruded.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hollow aluminum rod extrusion forming machine, comprising a base and a lifting plate slidably arranged on the top of the base, a hydraulic mechanism for driving the lifting plate to move is arranged on the top of the base, and mounting grooves are provided on the side surfaces facing the lifting plate, an extrusion die is detachably embedded and fixed in the mounting groove, and receiving grooves are provided on both sides of the inner wall of the mounting groove, and positioning grooves are provided on the inner walls of the two extrusion dies, a support frame is fixed to the inner wall of one of the positioning grooves, a hollow aluminum rod body is slidably sleeved on the support frame, and a card block that is clamped with the extrusion die is elastically inserted in the receiving groove.

[0007] Preferably, positioning rods are fixed to the top of the base in a rectangular array, and a plurality of the positioning rods are slidably inserted in the lifting plate.

[0008] Furthermore, the hydraulic mechanism includes a top plate fixed on the top ends of the plurality of positioning rods and a hydraulic rod fixed on the top plate, and the hydraulic rod passes through the top plate and is fixedly connected to the lifting plate.

[0009] Furthermore, the outer walls of the base and the lifting plate are both protrudingly provided with a pull plate, and a pull rod fixed to the pull plate is slidably inserted in the accommodating groove.

[0010] Furthermore, a card slot is provided on the outer wall of the extrusion die, one end of the card block is fixedly connected to the pull rod, and the other end of the card block is fitted and inserted in the card slot.

[0011] Furthermore, the inner wall of the accommodating groove is symmetrically provided with telescopic holes, and a plurality of the telescopic holes respectively penetrate the base and the lifting plate.

[0012] Furthermore, telescopic rods are symmetrically fixed to the inner wall of the block, and the telescopic rods are slidably inserted in the telescopic holes.

[0013] Furthermore, a spring is sleeved and installed on the telescopic rod, and two ends of the spring are respectively in contact with the clamping block and the inner wall of the accommodating groove.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model provides mounting grooves on both the base and the lifting frame, in which an extrusion die is detachably fixed, and the outer wall of the hollow aluminum rod body is positioned through the mounting groove on the extrusion die. At the same time, the hollow aluminum rod body is sleeved on the support frame fixed on the inner wall of the mounting groove during extrusion molding, so that the support frame supports the inner wall of the hollow aluminum rod body, thereby reducing the problem of sliding and excessive deformation of the hollow aluminum rod due to extrusion.

[0016] (2) The utility model provides receiving grooves on both sides of the inner wall of the installation groove, and elastically inserts a card block that is engaged with the card slot in the receiving groove. The spring in the receiving groove pushes the card block to fit in the card slot on the outer wall of the extrusion die, so that the extrusion die remains fixed. When processing hollow aluminum rod bodies of different models, the pull plate is held by hand to drive the pull rod to move the card block out of the card slot. During the moving process, the telescopic rod slides in the telescopic hole, and the extrusion die is disassembled at the same time. The extrusion die with positioning grooves and support frames of different sizes can be replaced. The utility model is suitable for processing hollow aluminum rod bodies of different models.

[0017] In summary, the utility model has the advantages of reducing the problem of sliding and excessive deformation of the hollow aluminum rod caused by extrusion, being suitable for processing the main body of hollow aluminum rods of different models, and the like.
