Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically a multi-cavity metal gravity casting mold. Background Technology

[0002] Gravity casting is a process in which molten metal is poured into a mold under the influence of Earth's gravity; it is also known as gravity pouring. Gravity casting includes sand casting, metal mold casting, investment casting, lost foam casting, clay casting, etc. Metal mold gravity casting is a process in which hollow molds made of heat-resistant alloy steel are used for casting, and molten metal is poured into the hollow molds under the influence of Earth's gravity.

[0003] A search revealed that patent application CN207288803U discloses a metal gravity casting mold, including a base, a lower mold on the upper surface of the base, first protrusions at both ends of the lower mold, a piston rod passing through the first protrusions, a spring and a baffle sleeved on the piston rod, the baffle being positioned above the spring, an upper mold above the lower mold, and a magnet mounting block at one end of the rotating rod located inside the piston rod. This facilitates mold closing and opening, improving convenience.

[0004] However, due to the setting of the lower mold and the upper mold, after the molten metal is poured into the mold cavity, the molten metal cools and solidifies, which makes the surface of the metal casting prone to defects. The finished product of the casting is of poor quality and has a low pass rate. At the same time, after casting, the finished product needs to be manually removed from the mold cavity, which is inconvenient, time-consuming and labor-intensive.

[0005] Therefore, we propose a multi-cavity metal gravity casting mold. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-cavity metal gravity casting mold, which solves the problems of poor casting effect and inconvenient removal in existing methods.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-cavity metal gravity casting mold, including a mechanical box, wherein four sets of hydraulic telescopic rods in opposite positions are fixedly installed on the top surface of the mechanical box, and a top seat is fixedly installed on the top of each hydraulic telescopic rod;

[0008] A lower mold base is fixedly installed on the top surface of the machine box. The top surface of the lower mold base has four sets of lower mold cavities with opposite positions. An upper mold base with matching specifications is fixedly installed on the bottom surface of the top mold base. The bottom surface of the upper mold base has four sets of upper mold cavities with matching specifications. A pouring channel penetrating the top mold base is opened on the top surface of the upper mold cavity. A pouring port is fixedly installed on the top surface of the pouring channel. A pouring riser with opposite positions is opened on the top surface of the upper mold cavity. A connecting branch channel is opened between the pouring riser and the pouring channel. The pouring riser is spherical.

[0009] Support plates are fixedly installed on the left and right sides of the mechanical box. Two sets of electric telescopic rods with opposite positions are fixedly installed on the top surface of the support plates. A connecting block is fixedly installed at the top of the electric telescopic rod. A cylinder is fixedly installed on the right side of the connecting block. A fixing plate is fitted on the output end of the cylinder. A clamping block with the same specifications is fixedly installed on the right side of the fixing plate. A groove with the same specifications is opened on the right side of the clamping block.

[0010] Preferably, the inner wall of the lower mold cavity is provided with a vent riser, and the outer wall of the lower mold base is provided with four sets of vent holes connected to the vent riser. This allows the gas in the casting to be discharged, thereby improving the quality of the produced product.

[0011] Preferably, four sets of positioning rods are fixedly installed on the top surface of the lower mold base, which are positioned opposite each other and pass through the upper mold base and the top base. The positioning rods are slidably connected to the upper mold base and the top base, so as to accurately position the lower mold base and the upper mold base and ensure the accuracy of casting.

[0012] Preferably, a limit block is fixedly installed at the top of the positioning rod to prevent the upper mold base from falling off the positioning rod.

[0013] Preferably, the front of the mechanical box is equipped with control buttons, which facilitates the control of each component.

[0014] Preferably, the casting riser is made of refractory fiber material, which can improve the heat preservation effect of the casting riser, prolong the solidification time of the molten metal, improve the feeding effect, and thus improve the casting effect.

[0015] 1. This multi-cavity metal gravity casting mold, through the setting of an upper mold base, a pouring riser and a runner, allows molten metal to be injected into the mold cavity through the pouring channel. A portion of the liquid enters the pouring riser through the runner. The liquid in the mold cavity cools and solidifies. When defects occur, the liquid in the pouring riser, due to its slow solidification, automatically feeds back under the action of gravity, thereby improving the casting effect.

[0016] 2. Simultaneously, through the setting of electric telescopic rod, cylinder and clamping block, after casting is completed, the hydraulic telescopic rod drives the top seat to move upward, the cylinder drives the clamping block to move towards the connection between the pouring riser and the finished product, thereby clamping it, and then the electric telescopic rod drives the finished product to move upward, thereby completing the removal, which is simple and convenient and reduces labor.

Four sets of lower mold cavities 5 are formed on the top surface of the lower mold base 4, positioned opposite each other. An upper mold base 6 of the same specifications is fixedly installed on the bottom surface of the top base 3. Four sets of upper mold cavities 7 of the same specifications are formed on the bottom surface of the upper mold base 6. A pouring channel 8 penetrating the top base 3 is formed on the top surface of the upper mold cavity 7. A pouring port 9 is fixedly installed on the top surface of the pouring channel 8. A pouring riser 11 is formed on the top surface of the upper mold cavity 7, positioned opposite each other. A connecting channel 10 is provided between the casting riser 11 and the casting channel 8.

A part of the liquid enters the casting riser 11 through the channel 10. The liquid in the mold cavity cools and solidifies. When defects occur, the liquid in the casting riser 11 will automatically shrink under the action of gravity due to slow solidification, thereby improving the casting effect.

[0027] Example 2:

[0028] like Figure 2-6 As shown: Support plates 16 are fixedly installed on the left and right sides of the machine box 1. Two sets of electric telescopic rods 17 with opposite positions are fixedly installed on the top surface of the support plates 16.

With the electric telescopic rod 17, cylinder 19 and clamping block 21, after casting is completed, the hydraulic telescopic rod 2 drives the top seat 3 to move upward. The cylinder 19 drives the clamping block 21 to move towards the connection between the pouring riser 11 and the finished product, thereby clamping it. Then the electric telescopic rod 17 drives the finished product to move upward, thereby completing the removal. It is simple and convenient and reduces labor.

[0029] Example 3:

This allows the gas in the casting to be discharged, thereby improving the quality of the produced products.

[0031] The working principle and usage process of this utility model are as follows: When the device is required to work, molten metal is injected into the mold cavity through the casting channel 8. A portion of the liquid enters the casting riser 11 through the diversion channel 10. The liquid in the mold cavity cools and solidifies. When defects occur, the liquid in the casting riser 11 automatically feeds back under the action of gravity due to slow solidification, thereby improving the casting effect. After casting is completed, the hydraulic telescopic rod 2 drives the top seat 3 to move upward, and the cylinder 19 drives the clamping block 21 to move towards the connection between the casting riser 11 and the finished product, thereby clamping it. Then, the electric telescopic rod 17 drives the finished product to move upward, thereby completing the removal. It is simple and convenient, reducing labor.
