Technical Field

[0001] This utility model relates to the field of stainless steel powder technology, specifically to an automatic injection molding device for stainless steel powder. Background Technology

[0002] Stainless steel powder is a fine particulate substance made of stainless steel material. It has unique physical and chemical properties and is widely used in many industrial fields.

[0003] Currently, in order to improve product production efficiency, stainless steel powder is injected into the mold cavity, and after extrusion, a blank can be obtained directly. After sintering the blank, the finished product can be obtained directly.

[0004] However, current injection molding equipment has a simple structure and cannot be linked with the conveyor. As a result, after molding, the blank needs to be placed on the conveyor manually or by mechanical grippers for subsequent operations, which affects production efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an automatic injection molding device for stainless steel powder, which can directly pour out the internal blank by rotating the ball and make it directly contact the conveyor, so as to solve the problems mentioned in the background art.

[0010] As a preferred technical solution, fixing plates are installed on both sides of the fixing base, and each fixing plate is provided with multiple straight slots.

[0011] As a preferred technical solution, a clearance space is formed between the end of the extrusion column away from the fixed seat and the end of the cylinder away from the fixed seat to allow the extrusion column to rise.

[0012] As a preferred technical solution, a second cylinder is installed on the end face of the cylinder, and the piston rod of the second cylinder passes through the cylinder and is fixedly connected to the extrusion column.

[0013] The beneficial effects of this utility model are: This utility model has a simple structure.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses an automatic stainless steel powder injection molding device, including a fixed base 1 mounted on a conveyor. The fixed base 1 has a discharge groove 2 on one end face facing the conveyor belt. A ball groove is provided at the center of the discharge groove 2. A ball 9 is provided in the ball groove. A mold cavity 10 is provided on the ball 9. The fixed base 1 has a feed hole 11 communicating with the mold cavity 10 on one end face away from the conveyor belt. A cylinder 3 communicating with the feed hole 11 is installed on one end face of the fixed base 1. An extrusion column 12 is provided inside the cylinder 3. An injection tube is installed on one side face of the cylinder 3. The opening at one end of the injection tube is sealed by the extrusion column 12.

[0024] The fixed base is equipped with a vibrator. The vibration energy generated by the vibrator acts on the fixed base, the ball, and the feed pipe. After the ball rotates, the vibration energy acting on the ball will shake the formed blank out of the mold cavity and drop it onto the conveyor belt of the conveyor. Since the conveyor belt is made of rubber, it can play a buffering role. In addition, the distance between the ball and the conveyor belt is relatively close, less than 4 cm, which reduces the falling height and avoids the probability of the blank being damaged.

[0025] The vibration acting on the feed pipe allows the stainless steel powder to quickly pass through the feed pipe and the cylinder into the mold cavity.

[0026] In this embodiment, the inner ring surface of the ball groove is provided with a positioning hole and a shaft hole, which are arranged opposite to each other. A positioning rod 13 is installed on the outer ring surface of the ball 9, which is directly opposite the positioning hole. The positioning rod 13 is inserted into the positioning hole. A motor 8 is installed on the outer wall surface of the fixing seat 1, which is directly opposite the shaft hole. The rotating shaft of the motor 8 passes through the shaft hole and is installed on the outer wall surface of the ball 9.

[0027] The positioning rod can be used to position the ball, so that the ball can only rotate around the positioning rod.

[0028] In this embodiment, a through hole is provided on the inner ring surface of the ball groove, and an insertion hole is provided on the outer wall surface of the ball 9 opposite to the through hole. A first cylinder 7 is installed on the outer wall surface of the fixing base 1 opposite to the through hole. The piston rod of the first cylinder 7 passes through the through hole and is inserted into the insertion hole.

[0029] The piston rod of the first cylinder can position the ball, preventing the ball from rotating around the positioning rod, thus ensuring that the extrusion column can smoothly enter the mold cavity.

[0030] In this embodiment, the inner walls of the cylinder 3, the feed port, and the mold cavity 10 are flush, so that the extrusion column can smoothly pass through the cylinder and the feed port into the mold cavity.

[0031] In this embodiment, fixing plates 6 are installed on both sides of the fixing base 1. Each fixing plate 6 has multiple straight slots and can be fixed to the frame of the conveyor by screws.

[0032] In this embodiment, a clearance space is formed between the end of the extrusion column 12 away from the fixed seat 1 and the end of the cylinder 3 away from the fixed seat 1, allowing the extrusion column 12 to rise.

[0033] In this embodiment, a second cylinder 4 is installed on the end face of the cylinder 3. The piston rod of the second cylinder 4 passes through the cylinder 3 and is fixedly connected to the extrusion column 12.

[0034] The feed pipe is equipped with a metering valve. The metering valve, the first cylinder, the second cylinder, and the motor are all controlled by a microcontroller. The above components are controlled by programming so that they can start and stop automatically and gradually. The metering valve can control the amount of stainless steel powder injected at one time.

[0035] The other end of the feed pipe is connected to the storage hopper, which contains stainless steel powder. Therefore, after the piston rod of the second cylinder retracts, it can drive the extrusion column to rise. As the extrusion column rises, the opening of the feed pipe can connect with the cylinder. At this time, the stainless steel powder can enter the cylinder through the feed pipe and be automatically injected into the mold cavity through the feed hole. As the piston rod of the second cylinder extends, it can drive the extrusion column to descend and block and seal the opening of the feed pipe to prevent further entry. The descending extrusion column can also compress the stainless steel powder inside the mold cavity to form a blank.

[0036] After the above is completed, the first cylinder is activated, causing the piston rod of the first cylinder to be pulled out of the insertion hole. After the obstruction of the first cylinder is removed, the motor can be started. The motor can drive the rotation of the ball, so that the opening of the ball is set downward. At this time, the blank inside can fall directly out and fall onto the conveyor belt of the conveyor, and can be directly transported to the next step, which greatly increases efficiency and reduces the waste of time in the intermediate process.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
