Several insert rods are fixed at equal angles on the right end of the die-casting head, and these insert rods are movably inserted into grooves on the side wall of the extrusion cylinder. The die-casting head and the extrusion cylinder are in contact. A fixing ring is fixedly sleeved on the left end of the extrusion cylinder, and a groove is formed on the fixing ring. Several positioning grooves are formed at equal angles on the inner wall of the groove. One end of a positioning plate is screwed into a positioning groove using a spring-loaded rotating rod, and a positioning rod is fixed on the positioning plate. A positioning ring is fixedly sleeved on the die-casting head, and the positioning ring is movably engaged in the groove. The positioning plate and the positioning ring are in contact. Using the guiding action of the insert rods, the die-casting head is quickly installed at the end of the extrusion cylinder. Rotating the positioning plate causes it to contact the positioning ring, restricting the position of the positioning ring, thereby quickly fixing the die-casting head onto the extrusion cylinder. This facilitates quick replacement of different die-casting head models.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes an extrusion cylinder 1; the extrusion cylinder 1 is a cylindrical structure with an opening at the left end and a hollow interior;

[0028] It also includes:

[0029] The die head base 2 has several insertion rods 3 fixed at equal angles on its right end, and the insertion rods 3 are movably inserted into the groove on the side wall of the extrusion cylinder 1. The die head base 2 and the extrusion cylinder 1 are fitted together and abutted against each other. The positioning effect of the insertion rods 3 is used to movably insert the die head base 2 into the end of the extrusion cylinder 1.

[0030] The fixing ring 4 is fixedly sleeved on the left end ring wall of the extrusion cylinder 1, and the fixing ring 4 has a groove 5. Several positioning grooves 6 are opened through the inner wall of the groove 5 at equal angles. The fixing ring 4 plays a positioning role. Several clamping plates 20 are provided on the ring wall of the fixing ring 4 at equal angles using bolts. The clamping plates 20 are set to cooperate and abut against the positioning plate 7, which facilitates the restriction of the position of the positioning plate 7 and improves the stability of the position of the positioning plate 7.

[0031] Positioning plate 7, there are several positioning plates 7, one end of which is screwed into the positioning groove 6 by a spring-loaded rotating rod. Positioning rod 8 is fixed on the positioning plate 7. The positioning plate 7 rotates in the positioning groove 6 by the action of the spring-loaded rotating shaft.

[0032] The positioning ring 9 is fixedly sleeved on the headstock 2 and is movably locked in the groove 5. The positioning plate 7 and the positioning ring 9 are engaged in abutment. The rotation of the positioning plate 7 restricts the positioning ring 9 in the groove 5. Several positioning plates 7 have protrusions 21 fixed at their ends, and the protrusions 21 are engaged in abutment with the positioning ring 9. The protrusion of the protrusions 21 increases the contact area between the positioning plate 7 and the positioning ring 9.

[0033] Positioning component 10, wherein the positioning component 10 is disposed on the outer ring wall of the headstock 2, and the positioning component 10 is configured to abut against the positioning rod 8, the positioning component 10 comprising:

[0034] Positioning blocks 11, there are several positioning blocks 11, and they are fixed at equal angles on the outer ring wall of the machine head base 2. The positioning blocks 11 are provided with slots 12, and the positioning rods 8 are movably locked in the slots 12. The positioning blocks 11 restrict the end position of the positioning rods 8, thereby restricting the position of the positioning plate 7. The ring walls of the several positioning rods 8 and the inner wall of the slots 12 are provided with magnetic blocks 17, and the corresponding two magnetic blocks 17 are mutually attracted. The magnetic attraction of the magnetic blocks 17 is used to temporarily fix the positioning rods 8 and the positioning blocks 11.

[0035] The rotating ring 13 is screwed onto the ring wall of the machine head seat 2 using a bearing. Several arc-shaped plates 14 are fixed at equal angles on the rotating ring 13. The arc-shaped plates 14 are movably inserted into one end of the positioning block 11. The arc-shaped plates 14 are engaged with the positioning rods 8. The position of the arc-shaped plates 14 can be adjusted by the rotating ring 13 to facilitate the simultaneous fixing of several positioning rods 8. A rotating hole 18 is opened through the rotating ring 13, and a protective pad 19 is provided inside the rotating hole 18 to facilitate the operator to hold the rotating hole 18 and drive the rotating ring 13 to rotate.

[0036] The limiting block 15 is fixed on the ring wall of the machine head seat 2, and the positioning screw 16 passes through the limiting block 15 and is threaded onto the rotating ring 13. The position of the rotating ring 13 is fixed by the cooperation between the positioning screw 16 and the limiting block 15.

[0037] When using this utility model, the headstock 2 is quickly installed at the end of the extrusion cylinder 1 by positioning the insertion rod 3. After the positioning ring 9 is movably locked in the groove 5, the positioning rod 8 drives the positioning plate 7 to rotate, so that the protrusion 21 of the positioning plate 7 abuts against the positioning ring 9. With the magnetic attraction of the magnetic block 17, the end of the positioning rod 8 is temporarily fixed in the slot 12. Then, the rotation of the rotating ring 13 is controlled by the rotating hole 18. The rotating ring 13 drives several arc plates 14 to rotate synchronously, so that the arc plates 14 are movably inserted into the positioning block 11. The arc plates 14 restrict the positioning rod 8 in the slot, thereby limiting the position of the positioning plate 7. Then, the operator uses bolts to install the clamping plate 20 on the fixing ring 4, so that one end of the clamping plate 20 abuts against the corresponding positioning plate 7, limiting the position of the positioning plate 7 and preventing the positioning plate 7 connected to the spring-loaded shaft from being loosened by force, which would affect the sealing performance of the positioning ring 9.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] Using the guiding effect of the insert rod 3, the die head seat 2 is quickly installed at the end of the extrusion cylinder 1. Then, the positioning plate 7 is rotated so that the positioning plate 7 abuts against the positioning ring 9, restricting the position of the positioning ring 9, thereby quickly fixing the die head seat 2 on the extrusion cylinder 1, which facilitates the quick replacement of different models of die head seats 2.

[0040] The positioning component 10 is set up, and the position of the arc plate 14 is controlled by the rotating ring 13, so that the arc plate 14 closes the opening of the slot 12 and simultaneously restricts the ends of several positioning rods 8 on the positioning block 11, which facilitates the quick fixing of the positioning rods 8.

[0041] Magnetic blocks 17 are provided. Through the mutual attraction of the magnetic blocks 17, the positioning rod 8 is temporarily fixed in the slot 12.

[0042] The protrusion 21 is provided to increase the contact surface between the positioning plate 7 and the positioning ring 9, thereby improving the stability of the support provided by the positioning plate 7 to the positioning ring 9.

[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
