DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1 and Figure 2 The utility model provides a technical solution: a mold for a pipe joint, comprising: a lower mold base 1 and an upper mold base 3, a positioning rod 2 is inserted through a through hole on the top of the lower mold base 1, and the upper mold base 3 is installed on the top of the positioning rod 2;

[0023] A pull rod 4 is connected to one side of the lower die base 1, and a movable block 5 is connected to one side of the pull rod 4. A movable spring 6 is connected between the movable block 5 and the groove of the lower die base 1. The top of the movable block 5 is connected to a connecting rod 7 through a rotating shaft, and the end of the connecting rod 7 away from the movable block 5 is connected to a connecting rod 8 through a rotating shaft. A clamping block 9 is installed on one side of the connecting rod 8, and a docking block 10 is sleeved on the side of the clamping block 9 away from the connecting rod 8. A reset spring 11 is connected between the docking block 10 and the groove of the lower die base 1, and a top block 12 is installed on the top of the docking block 10. The clamping block 9 is plugged into one side of the docking block 10 through a groove matching the size of the clamping block 9.

[0024] During specific implementation, when the mold of the pipe joint needs to be demoulded, the pull rod 4 can be pulled upward, and the pull rod 4 drives the movable block 5 to move upward. Since the top of the movable block 5 is connected to the connecting rod 7 through the rotating shaft, and the other end of the connecting rod 7 is connected to the connecting rod 8 through the rotating shaft, the movable block 5 moves upward at this time, and the connecting rod 7 will rotate through the rotating shaft, and then the connecting rod 7 will push the connecting rods 8 on both sides to both sides, and at the same time move the block 9 on one side of the connecting rod 8 out of the groove of the docking block 10. Then, without the block 9 limiting the docking block 10, the docking block 10 will be reset by the reset spring 11 at the bottom, and drive the top block 12 moves upward, at this time, the pipe joint in the groove of the lower mold base 1 can be pushed out of the groove, so that the user can quickly demould. Conversely, the top block 12 can be squeezed downward, and the top block 12 moves downward and squeezes the clamping block 9 to one side through the arc surface, and at the same time, the connecting rod 8 drives the movable block 5 to move upward through the connecting rod 7. When the clamping block 9 moves to one side of the docking block 10, the movable block 5 is reset by the movable spring 6, and the movable block 5 moves downward, so that the clamping block 9 is connected to the groove of the docking block 10 through the connecting rod 7 and the connecting rod 8, and the top block 12 is limited, which will not affect the normal processing of the pipe joint.

[0025] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 It can be seen that when demoulding is required, the movable block 5 is pulled, and then the docking block 10 is reset by the reset spring 11, so that the pipe joint is pushed out from the lower mold base 1, which is convenient for users to demould.

[0026] Fixed blocks 13 are installed on both sides of the lower mold base 1, and a screw 14 is connected to the inside of the fixed block 13. A pressure block 15 is connected to one side of the screw 14 through a bearing. The pressure block 15 passes through the lower mold base 1 away from the screw 14 and connects to one side of the positioning rod 2. A sealing strip 16 is installed on the top of the lower mold base 1 through a groove, and a protrusion 17 is provided on the top of the sealing strip 16. The protrusion 17 and the upper mold base 3 are an integrated structure.

[0027] In a specific implementation, when the mold of the pipe joint is sealing the gap between the upper mold base 3 and the lower mold base 1, the positioning rod 2 at the bottom of the upper mold base 3 can be docked with the lower mold base 1, so that the upper mold base 3 and the lower mold base 1 are docked, and at the same time, the groove of the positioning rod 2 also moves to one side of the pressing block 15, and the screw rod 14 is rotated at this time. Since the screw rod 14 and the fixed block 13 are threadedly connected, and the screw rod 14 and the pressing block 15 are connected by a bearing, the rotating screw 14 will drive the pressing block 15 to move, and the pressing block 15 passes through the inclined surface. The groove is connected to the groove of the positioning rod 2. When the pressure block 15 moves, it will push the positioning rod 2 downward through the inclined groove, so that the positioning rod 2 drives the upper mold base 3 to move downward, so that the upper mold base 3 and the lower mold base 1 are tightly fitted, and the protrusion 17 at the bottom of the upper mold base 3 is connected to the groove of the lower mold base 1, which squeezes the sealing strip 16 in the groove of the lower mold base 1. The sealing strip 16 is deformed when squeezed, so that the sealing effect of the entire mold is better, and damage is avoided during the production of pipe joints.

[0028] See also Figure 1 , Figure 2 and Figure 4 It can be known that when in use, the screw rod 14 can drive the pressing block 15 to move, and the pressing block 15 can make the lower die base 1 and the upper die base 3 fit closely, and make the sealing effect better.

[0029] To sum up: when the mold of the pipe joint is in use, the raw materials for producing the pipe joint can be poured into the groove of the lower mold base 1, and then the upper mold base 3 is moved downward by the positioning rod 2, so that the upper mold base 3 and the lower mold base 1 are closely connected. At this time, the pipe joint can be extruded and formed by relying on the upper mold base 3 and the lower mold base 1. This is the prior art and will not be elaborated on here. This is the use feature of the mold of the pipe joint. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may 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 shall be included in the protection scope of the present invention.
