[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a carbon dioxide foaming extruder mold that is easy to disassemble, including a body 1. The body 1 is the prior art and is the main body of the extruder. A feeding port is arranged on its surface so that the carbon dioxide foaming board can be extruded. The outer wall on the left side of the body 1 is detachably mounted with an outer mold 2 through a positioning component 4. The inner side wall of the outer mold 2 is fixedly connected with two groups of left and right guide blocks 6. The guide blocks 6 are convex in shape and fit with the corresponding slide grooves of the body 1. A threaded groove 7 is provided on the left side of the body 1. Four groups of bolts 3 are slidably connected to the surface of the outer mold 2. The outer walls of the four groups of bolts 3 are threadedly connected to the inner walls of the threaded grooves 7. The outer mold 2 can be quickly fixed and positioned on the outer wall of the body 1 through the four groups of bolts 3.

[0032] Reference Figure 2 and Figure 4 The guide block 6 is slidably connected to the inner wall of the body 1, and a groove that matches the size of the convex bottom of the guide block 6 is opened at the top of the body 1, so that the guide block 6 can enter the interior of the body 1. Secondly, a guide groove that matches the convex bottom of the guide block 6 is opened inside the body 1, so that the guide block 6 can slide upward when entering the interior of the body 1 and will not separate from the inner wall of the body 1. The inner side wall of the outer mold 2 is in contact with the outer wall of the body 1, and a shielding component 5 is provided on the outer wall of the body 1.

[0033] Reference Figure 2-Figure 3 The shielding assembly 5 includes a slider 51, which is slidably connected to the outer side wall of the body 1. The outer side wall of the body 1 is provided with a guide groove that fits the slider 51, so that the slider 51 can only move laterally on the inner wall of the guide groove and will not separate from its inner wall. The shielding plate 53 is slidably connected to the inner wall on the left side of the body 1, and a slide groove is provided on the surface of the body 1, so that the shielding plate 53 can only move vertically on the surface of the body 1 and cannot separate from its inner wall. The inner wall of the slider 51 is elastically connected to the limit block 55 through the return spring 54, and the limit block 55 passes through and is slidably connected to the inner wall of the slider 51. The outer side wall of the body 1 is provided with multiple groups of card grooves, and the bottom end of the outer wall of the limit block 55 is carded with the inner wall of the card groove. The card connection between the two allows the slider 51 to be fixed at the position where the outer side wall of the body 1 moves, and a one-way limit is applied to it.

[0034] Reference Figure 2-Figure 3 One end of the return spring 54 is fixedly connected to the surface of the limit block 55, and the other end of the return spring 54 is fixedly connected to the inner wall of the slider 51. The function of the return spring 54 is to reset the position of the limit block 55 after being squeezed and moved. The outer wall of the slider 51 is hinged with a hinge rod 52, and the end of the hinge rod 52 away from the slider 51 is hinged with a baffle plate 53. When the baffle plate 53 moves upward, it will synchronously drive the slider 51 to move laterally on the inner wall of the body 1 through the hinge rod 52. The top of the outer wall of the outer mold 2 contacts the inclined surface of the bottom end of the baffle plate 53, and the contact between the two drives the baffle plate 53 to move upward on the inner wall of the body 1 through the upward movement of the outer mold 2.

[0035] Reference Figure 2 and Figure 5The positioning assembly 4 includes a wedge block 43, which is elastically connected to the inner wall of the top end of the body 1 through a limit spring 42. One end of the limit spring 42 is fixedly connected to the outer wall of the wedge block 43, and the other end of the limit spring 42 is fixedly connected to the inner wall of the top end of the body 1. The function of the limit spring 42 is to automatically reset the position of the wedge block 43 after it is squeezed and moved. The outer side wall of the wedge block 43 is fixedly connected to a moving rod 41. By pulling the moving rod 41, the wedge block 43 can be driven to move synchronously. The moving rod 41 is slidably connected to the inner wall of the top end of the body 1, and the wedge block 43 is slidably connected to the inner wall of the top end of the body 1. The outer side wall of the guide block 6 is provided with a slot, and the wedge block 43 is clamped with the inner wall of the slot. The clamping between the two drives the guide block 6 to fix the outer mold 2 on the inner wall of the body 1, so that it is convenient to fix it by the bolt 3.

[0036] Working principle: When installing the outer mold 2, first pull the limit block 55 to allow its bottom end to disengage from the slot at the current position of the side wall of the body 1, and allow the return spring 54 to be elastically compressed. At this time, the two sets of guide blocks 6 on the inner side of the outer mold 2 can be plugged into the corresponding grooves at the bottom end of the outer wall of the body 1. When the guide blocks 6 enter the inner wall of the body 1, the inner side wall of the outer mold 2 will contact the outer wall of the body 1. At this time, the guide blocks 6 can be driven to move upward on the inner wall of the body 1 by directly pushing the outer mold 2, and during the rising process, the top end of the outer mold 2 contacts the inclined surface at the bottom end of the baffle plate 53, thereby driving the baffle plate 53 to move upward on the inner wall of the body 1, and at the same time, the baffle plate 53 When rising, the sliding block 51 will be driven by the hinge rod 52 to move laterally on the inner wall of the body 1 until the guide block 6 moves to the top end, and its outer wall will squeeze the arc surface of the wedge block 43 at the current position, thereby driving the moving rod 41 to move outward synchronously, and allowing the limit spring 42 to be elastically compressed until the guide block 6 is completely moved to the top end. The wedge block 43 will be elastically acted upon by the limit spring 42, and it and the moving rod 41 will be synchronously restored to the initial position, thereby engaging with the card slot at the current position of the guide block 6, thereby fixing the position of the guide block 6 and the outer mold 2. At this time, the bolt 3 can be used to penetrate the outer mold 2 to be threadedly connected to the thread groove 7 corresponding to the body 1, thereby firmly fixing the outer mold 2.

[0037] At the same time, when the outer mold 2 is disassembled by the opposite operation, the baffle plate 53 will drop due to the action of gravity, thereby driving the hinge rod 52 to move, thereby driving the slider 51 to move to the left in the guide groove of the side wall of the body 1, and at the same time, the inclined surface at the bottom end of the limit block 55 will disengage from the slot at the current position of the side wall of the body 1, allowing the return spring 54 to be elastically compressed until the next set of slots, when it will be elastically acted upon by the return spring 54 to restore it to its initial position, and so on, thereby removing the side wall of the body 1 through the inclined surface at the bottom end of the baffle plate 53, and at the same time protecting the exterior of the body 1 to prevent dust from entering its inner wall.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
