Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a self-opening structure of a casting pouring piece. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (e.g., copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramic. Depending on the requirements, the methods used will also be different.

[0003] Publication No. CN214684261U discloses an automatic pouring device and a casting production line for automatic quantitative pouring.

[0004] However, the above application still has the following problems: during pouring, the measuring cylinder is tipped by a mechanical arm, and the casting piece, i.e., the measuring cylinder itself, does not have a self-opening function. Pouring and tipping easily cause the casting liquid to flow down along the side wall of the outer peripheral side wall of the measuring cylinder, and the side wall is contaminated with the casting liquid, resulting in a reduction in the amount of casting liquid coming out of the original quantitative measuring cylinder. Therefore, the utility model proposes a self-opening structure for a casting casting piece. Utility Model Content

[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a self-opening structure of a casting pouring piece.

[0006] The utility model proposes a self-opening structure for a casting pouring part, comprising a moving part, a pouring measuring cup and a mold, wherein the moving part is used to drive the pouring measuring cup to move, the pouring measuring cup is used to put the pouring liquid into the mold cavity, the pouring measuring cup is open, a blocking structure is provided on the pouring measuring cup, and an opening mechanism is installed on the mold, and the opening mechanism is used to open the blocking structure.

[0007] Preferably, the sealing structure includes a sealing plate, and the sealing plate is used to seal the pouring measuring cup. A fixed plate is installed on the pouring measuring cup, and the sealing plate is connected to the fixed plate. The sealing plate rotates on the fixed plate, and an elastic part is installed between the side of the sealing plate away from the pouring measuring cup and the fixed plate.

[0008] Preferably, the opening mechanism comprises a connecting plate mounted on the mold, and a trapezoidal block is mounted on one side of the connecting plate.

[0009] Preferably, a sealing block is installed on the sealing plate, and the sealing block is set to a cone shape. The conical sealing block enhances the sealing effect of the pouring measuring cup. However, it should be noted that due to the conical protrusion of the sealing block, the scale of the pouring measuring cup needs to be changed during production.

[0010] Preferably, the fixing plate is configured to be L-shaped.

[0011] Preferably, the elastic member is a spring or an elastic rod.

[0012] Preferably, the diameter of the blocking plate is larger than the diameter of the pouring measuring cup.

[0013] In the utility model, the self-opening structure of the casting pouring part proposed has the following beneficial technical effects:

[0014] Through the bevel setting of the trapezoidal block, the part of the sealing block protruding from the pouring measuring cup contacts and slides with the bevel of the trapezoidal block, thereby driving the sealing plate rotatably connected to the fixed plate to rotate, thereby realizing the automatic opening of the pouring measuring cup. Moreover, since there is no need to tip the pouring measuring cup, the situation in which the outer peripheral side wall of the measuring cylinder is contaminated with pouring liquid due to pouring is avoided.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] like Figure 1-Figure 3The self-opening structure of a casting pouring part shown in the figure includes a moving part 1, a pouring measuring cup 2 and a mold 3. The moving part 1 is used to drive the pouring measuring cup 2 to move, and the pouring measuring cup 2 is used to put the pouring liquid into the mold cavity of the mold 3. The moving part 1 is a mechanical arm or a pneumatic cylinder in the prior art. The moving part 1, the pouring measuring cup 2 and the mold 3 are the prior art. The pouring measuring cup 2 is open, and a blocking structure 4 is provided on the pouring measuring cup 2, and an opening mechanism 5 is installed on the mold 3. The opening mechanism 5 is used to open the blocking structure 4.

[0022] A further improvement of the technical solution is that the sealing structure 4 includes a sealing plate 41, and the sealing plate 41 is used to seal the bottom of the pouring measuring cup 2, a fixed plate 42 is installed on the pouring measuring cup 2, and the outer periphery of the sealing plate 41 is rotatably connected to the fixed plate 42, the sealing plate 41 rotates on the fixed plate 42, and an elastic member 43 is installed between the side of the sealing plate 41 away from the pouring measuring cup 2 and the fixed plate 42.

[0023] A further improvement of the technical solution is that the opening mechanism 5 includes a connecting plate 51 installed on the mold 3, and a trapezoidal block 52 is installed on one side of the connecting plate 51, and the cross-section of the trapezoidal block 52 is a right-angled trapezoid.

[0024] A further improvement of the technical solution is that the opening mechanism 5 can be replaced by other existing inclined surface mechanisms having an inclined surface on which the blocking plate 41 can slide, such as a triangular or diamond-shaped plate instead of the trapezoidal block 52 .

[0025] A further improvement of the technical solution is that a sealing block 6 is installed on the sealing plate 41, and the sealing block 6 is configured to be conical. The conical sealing block 6 enhances the sealing effect of the pouring measuring cup 2. However, it should be noted that due to the conical protrusion of the sealing block 6, the scale of the pouring measuring cup 2 needs to be changed during production.

[0026] In an optional embodiment, the fixing plate 42 is configured to be L-shaped.

[0027] In an optional embodiment, the elastic member 43 is a spring or an elastic rod.

[0028] In an optional embodiment, the diameter of the blocking plate 41 is greater than the diameter of the pouring measuring cup 2 .

[0029] Through the bevel setting of the trapezoidal block 52, when working, the pouring measuring cup 2 moves toward the mold 3 under the drive of the moving part 1. At this time, the part of the blocking block 6 protruding from the pouring measuring cup 2 contacts and slides with the bevel of the trapezoidal block 52, thereby driving the blocking plate 41 rotatably connected to the fixed plate 42 to rotate, thereby realizing the automatic opening of the pouring measuring cup 2. At this time, the elastic part 43 is in a compressed state. After the pouring is completed, as the pouring measuring cup 2 leaves, under the action of the elastic part 43, the blocking plate 41 returns to its original position and re-seals the bottom of the pouring measuring cup 2.

[0030] Furthermore, since there is no need to pour the pouring measuring cup 2, the situation in which the outer peripheral side wall of the measuring cylinder is contaminated with pouring liquid due to pouring is avoided. Moreover, when pouring, the tilting angle required for more liquid or less liquid in the measuring cylinder is different, which increases the difficulty of operating the robot arm. By adopting this solution, the pouring step can be omitted, thereby reducing the difficulty of operating the process.
