Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with rapid cooling function. Background Technology
[0002] An injection mold is a type of mold used for injection molding, and it is widely used in the production of plastic products. An injection mold injects molten plastic material into a mold cavity, which then cools and solidifies to produce the desired plastic product.
[0003] However, existing injection molds often use coolant to cool the inside of the mold. Over time, the cooling effect of the coolant will decrease, so the coolant needs to be replaced regularly. However, when replacing the coolant, the injection mold needs to be stopped, which reduces the injection efficiency of the injection mold and slows down the work progress. Utility Model Content
[0004] The purpose of this invention is to provide an injection mold with a rapid cooling function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold with rapid cooling function, comprising a mold frame, a motor fixedly mounted on the top of the mold frame, a reciprocating lead screw fixedly mounted on the bottom of the motor output shaft, a control block threadedly connected to the surface of the reciprocating lead screw, the control block slidably connected to the surface of the mold frame, an upper mold fixedly mounted on the bottom of the control block, a fixing block fixedly mounted inside the mold frame, a lower mold fixedly mounted on the top of the fixing block, and a fixing component and a movable component disposed inside the fixing block. When the cam rotates, the convex surface at the top of the cam abuts against the fixing plate and slides upward. When the fixing plate slides upward, it drives the cooling pipe to slide upward, thereby driving the hole on the left side of the cooling pipe to connect with the right side of the connecting pipe, achieving the effect of water flow. When the cooling pipe and the connecting pipe are connected, the water flows to the interior of the cooling tank through a water pump, and the coolant inside the cooling tank flows to the interior of the connecting block and the cooling pipe. The movable component includes:
[0006] A cooling box is fixedly installed on the inner wall of a fixing block and at the bottom of a lower mold. A connecting block is fixedly installed inside the cooling box and penetrates the bottom of the cooling box.
[0007] A cooling pipe is slidably connected inside a connecting block. The cooling pipe passes through the bottom of the connecting block and is fixedly mounted on the bottom of the cooling pipe. A fixing spring is fixedly mounted on the surface of the cooling pipe and is fixedly mounted on the bottom of the connecting block. A connecting pipe is fixedly mounted on the left side of the connecting block and fits against the left side of the cooling pipe. A water pump is fixedly mounted on the bottom of the connecting pipe and is fixedly mounted inside the fixing block. A conduit is fixedly mounted on the top of the water pump and is fixedly mounted on the bottom of the cooling tank.
[0008] A control lever is rotatably connected to the right side of a fixed block and passes through the right side of the fixed block. A cam is fixedly installed on the left side of the control lever and fits against the bottom of a fixed plate, thereby enabling the replacement of coolant. This improves the efficiency of the injection mold during use, accelerates the cooling effect, and enhances the convenience and work progress for operators.
[0009] Preferably, the fixing component includes: a turntable, the turntable being fixedly installed on the right side of the control lever, a handle being fixedly installed on the right side of the turntable, a slider being slidably connected to the surface of the handle, a movable spring being fixedly installed on the left side of the slider, and the movable spring being fixedly installed on the surface of the handle.
[0010] Preferably, a plug rod is fixedly installed on the left side of the slider, a top block is fixedly installed on the left side of the plug rod, a sliding block is slidably connected to the surface of the plug rod, a control spring is fixedly installed on the right side of the sliding block, and the control spring is fixedly installed on the surface of the plug rod.
[0011] Preferably, a limiting block is fixedly installed on the right side of the fixing block, and a limiting rod is slidably connected inside the limiting block. A return spring is fixedly installed on the surface of the limiting rod and is fixedly installed on the inner wall of the limiting block. When the insert rod penetrates the limiting block, the semi-circular tangent of the top block can abut against the conical tangent of the limiting rod, thereby driving the limiting rod to slide away from the limiting block. When the top block penetrates to the bottom of the limiting block, the limiting rod will reset under the action of the return spring, thereby making the limiting rod snap into the surface of the insert rod for restriction, improving the stability of the moving component during use, preventing accidental contact by outsiders from affecting the cooling efficiency of the injection mold, and improving the protection strength and protective effect of the injection mold.
[0012] Preferably, the surface of the cooling pipe has holes, which can be used to communicate with the connecting pipe.
[0013] Preferably, the surface of the limiting block has an insertion hole, which can drive the insertion rod through the limiting block for fixation.
[0014] Preferably, the top block has a semi-circular cross-section, allowing it to slide against the limiting rod; the sliding block has a rectangular cross-section, allowing it to move against the limiting rod; and the limiting rod has a conical cross-section, which improves the sliding effect of the limiting rod.
[0015] Compared with the prior art, this utility model provides an injection mold with rapid cooling function, which has the following beneficial effects:
[0016] 1. This injection mold with rapid cooling function utilizes the convex surface at the top of the cam to slide upward against the fixed plate when the cam rotates. As the fixed plate slides upward, it drives the cooling pipe to slide upward, thereby connecting the hole on the left side of the cooling pipe with the right side of the connecting pipe, achieving water flow. When the cooling pipe and the connecting pipe are connected, the water flows through the water pump into the interior of the cooling tank, and the coolant inside the cooling tank flows into the connecting block and the interior of the cooling pipe, thus achieving coolant replacement. This improves the efficiency of the injection mold during use, accelerates the cooling effect, and enhances the convenience and work progress for operators.
[0017] 2. This injection mold with rapid cooling function allows the top block's semi-circular tangent to abut against the tapered tangent of the limiting rod when the insert rod penetrates the limiting block. This causes the limiting rod to slide away from the limiting block. When the top block penetrates to the bottom of the limiting block, the limiting rod will reset under the action of the return spring, thus locking the limiting rod onto the surface of the insert rod for restriction. This improves the stability of the moving components during use, prevents accidental contact by outsiders from affecting the cooling efficiency of the injection mold, and enhances the protection and safety of the injection mold.

Detailed Implementation
[0022] like Figures 1-3 As shown, this utility model provides a technical solution: an injection mold with rapid cooling function, including a mold frame 1, a motor 2 fixedly installed on the top of the mold frame 1, a reciprocating screw 3 fixedly installed on the bottom of the output shaft of the motor 2, a control block 4 threadedly connected to the surface of the reciprocating screw 3, the control block 4 slidably connected to the surface of the mold frame 1, an upper mold 5 fixedly installed on the bottom of the control block 4, a fixing block 6 fixedly installed on the inside of the mold frame 1, a lower mold 7 fixedly installed on the top of the fixing block 6, and a fixing component 8 and a movable component 9 provided inside the fixing block 6. When the cam 910 rotates, the convex surface at the top of the cam 910 will abut against the fixing plate 94 and move upwards. When the fixed plate 94 slides upward, it will drive the cooling pipe 93 to slide upward, thereby connecting the hole 930 on the left side of the cooling pipe 93 with the right side of the connecting pipe 96, and realizing the effect of water flow. When the cooling pipe 93 and the connecting pipe 96 are connected, the water will flow to the interior of the cooling box 91 through the water pump 97, and the coolant inside the cooling box 91 will flow to the interior of the connecting block 92 and the cooling pipe 93. The movable component 9 includes: cooling box 91, connecting block 92, cooling pipe 93, fixed plate 94, fixed spring 95, connecting pipe 96, water pump 97, conduit 98, control rod 99, and cam 910.
[0023] The cooling box 91 is fixedly installed on the inner wall of the fixing block 6 and at the bottom of the lower mold 7. A connecting block 92 is fixedly installed inside the cooling box 91, penetrating the bottom of the cooling box 91. A cooling pipe 93 is slidably connected inside the connecting block 92, penetrating the bottom of the connecting block 92. A fixing plate 94 is fixedly installed at the bottom of the cooling pipe 93. A fixing spring 95 is fixedly installed on the surface of the cooling pipe 93, and is fixedly installed at the bottom of the connecting block 92. A connecting pipe 96 is fixedly installed on the left side of the connecting block 92, and the connecting pipe 96 is attached to the cooling pipe 93. On the left side, a water pump 97 is fixedly installed at the bottom of the connecting pipe 96. The water pump 97 is fixedly installed inside the fixed block 6. A conduit 98 is fixedly installed at the top of the water pump 97. The conduit 98 is fixedly installed at the bottom of the cooling box 91. The control rod 99 is rotatably connected to the right side of the fixed block 6 and passes through the right side of the fixed block 6. A cam 910 is fixedly installed on the left side of the control rod 99. The cam 910 is attached to the bottom of the fixed plate 94, thereby realizing the replacement of coolant, improving the efficiency of the injection mold during use, accelerating the cooling effect, and improving the convenience and work progress of the staff.
[0024] The fixing component 8 includes: a turntable 81, which is fixedly installed on the right side of the control lever 99; a handle 82 is fixedly installed on the right side of the turntable 81; a slider 83 is slidably connected to the surface of the handle 82; a movable spring 84 is fixedly installed on the left side of the slider 83 and is fixedly installed on the surface of the handle 82; an insertion rod 85 is fixedly installed on the left side of the insertion rod 85; a top block 86 is fixedly installed on the left side of the insertion rod 85; a sliding block 87 is slidably connected to the surface of the insertion rod 85; a control spring 88 is fixedly installed on the right side of the sliding block 87 and is fixedly installed on the surface of the insertion rod 85; a limiting block 89 is fixedly installed on the right side of the fixing block 89; a limiting rod 810 is slidably connected inside the limiting block 89; a return spring 811 is fixedly installed on the surface of the limiting rod 810 and is fixedly installed on the inner wall of the limiting block 89; when the insertion rod 85 penetrates the limiting block 89, the semi-circular tangent of the top block 86 can abut against the conical tangent of the limiting rod 810, thereby driving the limiting rod 810... The top block 86 slides away from the end of the limiting block 89. When the top block 86 passes through to the bottom of the limiting block 89, the limiting rod 810 will be reset by the return spring 811, so that the limiting rod 810 is locked on the surface of the insertion rod 85 for restriction, improving the stability of the moving component 9 during use, preventing accidental contact by outsiders from affecting the cooling efficiency of the injection mold, and improving the protection and protective effect of the injection mold. The cooling pipe 93 has a hole 930 on its surface, which can be used to communicate with the connecting pipe 96. The limiting block 89 has an insertion hole 890 on its surface, which can drive the insertion rod 85 through the limiting block 89 for fixation. The top block 86 has a semi-circular cross section, which can be used to slide against the limiting rod 810. The sliding block 87 has a rectangular cross section, which can be used to move against the limiting rod 810. The limiting rod 810 has a conical cross section, which can improve the sliding effect of the limiting rod 810.
[0025] When the injection mold is in use, the reciprocating screw 3 can be rotated by starting motor 2. When the reciprocating screw 3 rotates, it will cause control block 4 to slide downward on the surface of mold holder 1. When control block 4 slides downward, it will cause upper mold 5 to slide downward into the interior of lower mold 7, thus enabling operation. When the cooling effect of the coolant for mold cooling decreases, the turntable 81 can be rotated by turning handle 82. When turntable 81 rotates, it will cause control lever 99 to rotate. When control lever 99 rotates, it will cause cam 910 to rotate. When cam 910 rotates, the convex surface at the top of cam 910 will abut against the mold. The fixed plate 94 slides upward, which in turn drives the cooling pipe 93 to slide upward. This connects the hole 930 on the left side of the cooling pipe 93 with the right side of the connecting pipe 96, allowing water to flow. When the cooling pipe 93 is connected to the connecting pipe 96, the water flows through the water pump 97 into the cooling tank 91. The coolant inside the cooling tank 91 flows into the connecting block 92 and the cooling pipe 93, thus replacing the coolant. This improves the efficiency of the injection mold during use, accelerates the cooling effect, and enhances the convenience and work progress for the operators.
[0026] During coolant replacement, the slider 83 can be slid from the surface of handle 82 towards the surface of control block 4. When slider 83 slides, it will cause the insert rod 85 to slide to the left. When insert rod 85 slides, it will cause top block 86 and sliding block 87 to slide to the left, thereby causing insert rod 85 to pass through limiting block 89. When insert rod 85 passes through limiting block 89, the semi-circular tangent of top block 86 can abut against the conical tangent of limiting rod 810, thereby causing limiting rod 810 to slide away from limiting block 89. When top block 86 passes through to the bottom of limiting block 89, limiting rod 810 will be reset by the action of return spring 811, thereby causing limiting rod 810 to be locked onto the surface of insert rod 85 for restriction, improving the stability of moving component 9 during use, preventing accidental contact by outsiders from affecting the cooling efficiency of injection mold, and improving the protection and protective effect of injection mold.
[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
