DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] Reference Figure 1 and Figure 2, a quick-release upper mold structure includes a mold base 1 and an upper mold plate 2. The opposite side walls of the mold base 1 can be detachably fixed with a fixing component 3, and a locking block 4 can be detachably fixed on the fixing component 3. The locking block 4 is vertically arranged and its length extends out of the bottom surface of the mold base 1. The portion of the locking block 4 extending out of the bottom surface of the mold base 1 is provided with a first U-shaped groove 41 penetrating its side wall. The opposite side walls of the upper mold plate 2 can be detachably fixed with a cylindrical lock head 5 whose diameter matches the upper and lower side wall spacing of the first U-shaped groove 41. When installing the upper mold plate 2, the upper mold plate 2 is horizontally inserted between the locking blocks 4 on the opposite side walls of the mold base 1, and the top surface of the upper mold plate 2 is in contact with the bottom surface of the mold base 1. The locking blocks 4 on the opposite side walls of the mold base 1 are The blocks 4 are respectively attached to the opposite side walls of the upper template 2 to clamp the upper template 2, and the circular lock head is inserted into the first U-shaped groove 41 to obtain the support of the locking block 4 to realize the installation and fixation of the upper template 2. The upper template 2 can be driven to move up and down by the mold base 1. The technicians in this field can reasonably set the size and relative position of the locking block 4 and the cylindrical lock head 5 so that the cylindrical lock head 5 is in the first U-shaped groove 41 of the locking block 4 when the upper template 2 and the mold base 1 are accurately installed, and can provide better support to ensure the upper template 2 and the mold are stable; when removing the lower template, the upper template 2 and the mold base 1 can be disassembled and separated by pulling the upper template 2 horizontally to make the cylindrical lock head 5 leave the first U-shaped groove 41, which is simpler and faster;

[0017] Reference Figure 1 There are two fixing components 3 fixed on each side wall of the mold base 1, and the two fixing components are gradually arranged in a horizontal interval. The number of locking blocks 4 is correspondingly two, and the number of cylindrical locks 5 fixed on each side wall of the upper template 2 is correspondingly two. By adopting this design, while keeping the upper template 2 and the mold base 1 installed stably, the sizes of the fixing components 3, the locking blocks 4, and the cylindrical locks 5 are reduced to achieve the purpose of saving materials.

[0018] Reference Figure 1 A quick-release upper mold structure also includes two connecting rods 6. The two locking blocks 4 on the same side wall of the mold base 1 are fixedly connected to a connecting rod 6. The two locking blocks 4 are fixed by the connecting rod 6 so that the two locking blocks 4 are linked as a whole. When installing and fixing the locking blocks 4, only one locking block 4 needs to be located, which is more convenient.

[0019] Reference Figure 1 , Figure 2 and Figure 3Furthermore, each fixing component 3 includes a rectangular block 31, a first bolt 32 and a second bolt 33. Two installation grooves 11 are provided on the opposite side walls of the mold base 1 to respectively correspond to the installation and fixation of the two fixing components 3. The spacing between the upper and lower side walls of the installation groove 11 matches the height of the rectangular block 31. The length of the installation groove 11 matches the length of the rectangular block 31. The depth of the installation groove 11 is less than the width of the rectangular block 31. The rectangular block 31 is embedded in the installation groove 11. The rectangular block 31 is fixed to the mold base 1 by a first bolt 32. The upper and lower side walls of the rectangular block 31 protruding from the mounting groove 11 are both concavely provided with grooves 311 penetrating through the two end surfaces thereof. The locking block 4 is provided with a second U-shaped groove 42 penetrating through the side wall thereof. The spacing between the upper and lower side walls of the second U-shaped groove 42 matches the height of the rectangular block 31. The upper and lower side walls of the second U-shaped groove 42 are both convexly provided with limiting protrusions 43. The convex height of the limiting protrusions 43 matches the height of the rectangular block 31. The depth of the groove 311, the locking block 4 is inserted into the rectangular block 31 through the second U-shaped groove 42, and the limiting protrusions 43 convexly arranged on the upper and lower side walls of the second U-shaped groove 42 are respectively inserted into the grooves 311 concavely arranged on the upper and lower side walls of the rectangular block 31, and the rectangular block 31 and the locking block 4 are fixed by the second bolts 33. With the above design, the installation groove 11 locates the installation position of the rectangular block 31, so that the rectangular block 31 is accurately positioned on the mold base 1, and the locking block 4 withstands the upper template 2. The rectangular block 31 supports the locking block 4, and the rectangular block 31 is limited by the inner wall of the installation groove 11. The rectangular block 31 is not easily displaced when subjected to force, so that the installation of the rectangular block 31 is relatively stable; the locking block 4 is inserted into the rectangular block 31 from the end face of the rectangular block 31 to achieve installation, and the limiting protrusion 43 is limited by the groove 311. The locking block 4 is not easily displaced when subjected to force, and the installation is relatively stable. It is a well-known technology to use bolts to fix it detachably, and it is not repeated in this embodiment.

[0020] Reference Figure 4 Furthermore, the cylindrical lock head 5 includes a cylindrical lock head 5 body and a third bolt 52. The third bolt 52 penetrates the cylindrical lock head 5 body from the middle of the cylindrical lock head 5 body and is fixedly connected to the cylindrical lock head 5 body. The cylindrical lock head 5 body is fixed to the upper template 2 by the third bolt 52. Similarly, the use of bolt fixing for detachable fixing is a well-known technology and is not described in detail in this embodiment.
