In addition, the embodiments of the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0036] The front, rear, left and right directions mentioned below refer to Figure 2 , Figure 2 The front, rear, left and right directions mentioned below refer to Figure 2 The vertical direction of the paper mentioned below refers to the up and down direction.

[0037] Referring to Figure 1 , the present embodiment provides a mold quick-change mechanism for locking a mold 1 in a housing 2. The mold 1 and the housing 2 are connected by matching the circular-arc grooves 11 and the circular-arc flanges 21 provided thereon one by one. The mold 1 can rotate along the circumference of the housing 2. Specifically, the housing 2 and the mold 1 are both semi-circular-arc-shaped vertical columns. The upper inner side (i.e. the rear side) of the housing 2 is provided with a circular-arc flange 21, and the upper outer side (i.e. the front side) of the mold 1 is provided with a circular-arc groove 11. The circular-arc flange 21 can be matched and clamped into the circular-arc groove 11. The mold 1 can rotate along the circumference of the housing 2 at the connection between the mold 1 and the housing 2, so as to realize the relative assembly and disassembly of the two.

[0038] Referring to Figures 1-3 As shown in the figure, the above-mentioned mold quick-change mechanism includes a first limiting mechanism 3 and a second limiting mechanism 4 respectively arranged at the left and right ends of the shell 2 and used for limiting the left and right ends of the mold 1 one by one, and the mold 1 is correspondingly provided with limiting grooves 12 used for being clamped into the first limiting mechanism 3 and the second limiting mechanism 4.

[0039] Among them, the first limiting mechanism 3 includes a fixed seat 31 arranged at the left end of the shell 2 and having a hollow inner cavity, a limiting shaft 32 slidably arranged in the fixed seat 31 along the left-right direction, and an elastic member 33 arranged in the fixed seat 31 and used for providing driving force to drive the limiting shaft 32 to slide to the right. The left and right ends of the limiting shaft 32 can respectively extend out of the left and right ends of the fixed seat 31, and the first limiting mechanism 3 further includes a blocking member 34 arranged outside the left end of the fixed seat 31 and used for connecting the left end of the limiting shaft 32. The blocking member 34 is blocked outside the fixed seat 31.

[0040] In this embodiment, the elastic member 33 is a spring sleeved on the limiting shaft 32. Referring to Figure 4 As shown in the figure, a limiting convex ring 321 for abutting against the right end of the elastic member 33 is radially and convexly arranged at the middle right position of the limiting shaft 32.

[0041] Referring to Figures 2-3 As shown in the figure, the first limiting mechanism 3 further includes a bearing 35 arranged in the fixed seat 31 and used for abutting against the left end of the elastic member 33. The limiting shaft 32 is not only slidably arranged in the bearing 35 along the left-right direction, but also rotatably arranged in the bearing 35 around the axis of the limiting shaft 32.

[0042] Based on the above structure, the limiting shaft 32 has a limiting state and an unlocking state:

[0043] Referring to Figure 2 As shown in the figure, the limiting shaft 32 is in the limiting state. Since the left end of the elastic member 33 remains stationary, under the elastic force of the elastic member 33, the right end of the limiting shaft 32 extends out of the right end of the fixed seat 31 to the right and is used for covering the left end of the mold 1 along the front-back direction. At this time, the blocking member 34 is pulled to the left end of the fixed seat 31 by the limiting shaft 32;

[0044] Referring to Figure 3 As shown in the figure, the limiting shaft 32 is in the unlocking state. The blocking member 34 is spaced apart from the left end of the fixed seat 31 by pulling it to the left, and the limiting shaft 32 moves to the left synchronously. The right end of the limiting shaft 32 moves away from the mold 1 to the left, and at this time the elastic member 33 is pushed to the left by the limiting convex ring 321 and compressed.

[0045] When the above-mentioned limiting shaft 32 is in the limiting state, the limiting shaft 32 covers the left end of the mold 1 through the part located to the right of the limiting convex ring 321.

[0046] Referring to Figures 4-5 As shown in the figure, in the embodiment, a threaded hole 342 is formed in the blocking piece 34, and an outer thread 322 is arranged at the left end of the limiting shaft 32. The blocking piece 34 and the limiting shaft 32 are screwed together. Through this arrangement, the quick assembly and disassembly between the two can be achieved.

[0047] The above-mentioned blocking piece 34 includes a plate body 341 perpendicular to the limiting shaft 32. When the limiting shaft 32 is in the unlocked state, the plate body 341 is used to hook the left side of the left end of the shell 2 after being turned through a set angle. Through this arrangement, the mold 1 can be conveniently taken out, avoiding interference and damage caused by the rebound of the limiting shaft 32 during the taking-out process.

[0048] Referring to Figure 5 As shown in the figure, in the embodiment, the plate body 341 is rectangular. When the limiting shaft 32 is in the limiting state, the plate body 341 is used to abut against the back side of the left end of the shell 2 through its long side; when the limiting shaft 32 is in the unlocked state, the plate body 341 is pulled out and rotated by 90°, and the plate body 341 can be hooked on the left side of the left end of the shell 2.

[0049] Referring to Figure 1 As shown in the figure, the first limiting mechanism 3 is multiple, two in the embodiment, and the two first limiting mechanisms 3 are arranged in sequence at the left end of the shell 2 along the length extension direction of the shell 2 (i.e. the up-down direction). Through the arrangement of multiple first limiting mechanisms 3, the limiting effect on the mold 1 can be ensured.

[0050] Referring to Figure 1 As shown in the figure, the second limiting mechanism 4 includes a pressing plate 41 for covering the right end of the mold 1 along the front-back direction, and a fixing piece 42 for installing the pressing plate 41 on the shell 2. The pressing plate 41 is generally not removed, and is only used to limit the right end of the mold 1. When the mold 1 needs to be replaced, only the limiting shafts 32 in the multiple first limiting mechanisms 3 on the left side need to be adjusted to the unlocked state respectively.

[0051] The working process of the embodiment will be specifically described below:

[0052] When the mold 1 needs to be replaced, the blocking piece 34 is pulled to move to the outside of the left end of the shell 2, and then the blocking piece 34 is rotated to hook on the left end of the shell 2. At this time, the elastic member 33 is compressed and stored, the right end of the limiting shaft 32 is away from the left end of the mold 1, and the mold 1 can be taken out and replaced by rotating along the circumferential direction of the shell 2 to the left;

[0053] After the replacement is completed, the blocking piece 34 is pulled out to the left and rotated to reset. Under the driving of the elastic restoring force of the elastic member 33, the limiting shaft 32 drives the blocking piece 34 to move to the right as a whole until the blocking piece 34 abuts against the left end outside of the fixed seat 31. At this time, the limiting shaft 32 realizes the limiting of the mold 1 through the right end part thereof.

[0054] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
