[0014] The present invention provides a rapid injection molding mold. It has the following beneficial effects:

[0015] 1. For the convenience of demoulding, when the movable mold drives the push block to contact the fixed plate, the push block will drive the sleeve rod to move into the demoulding column, so that the arc block will squeeze the transmission block back and forth to move downward.

[0016] 2. The rapid injection molding mold can drive the fixed rod to move when the demoulding column moves, and the C-rod can be moved in the inclined groove section of the slide groove through the fixed block, so that the slide plate can be squeezed to move downward, driving the L-shaped connecting rod to move, and the two sets of positioning plates can be close to each other through the cooperation of the connecting seat and the connecting column, so that the demoulding workpiece can be centered through the positioning plate, so that it is convenient for the staff to take it, and it can prevent the workpiece from falling off the demoulding and causing damage. During the injection molding operation, when the burr of the workpiece is too large, when the workpiece is centered, the positioning plate will move the burr of the workpiece, and the L-shaped limit rod can be moved out of the limit hole through the connecting column, so that the limit on the extrusion plate can be released, and the workpiece can be pushed to the back of the equipment through the extrusion plate, so as to prevent the staff from taking it, and it can also serve as a reminder for the staff to repair the mold.

[0017] 3. The rapid injection molding mold can prevent the disc from being blocked when the extrusion plate rotates, and through the cooperation of the fixed spring, the fixed spring can drive the card block to move downward, so that the card block is stuck in the button of the controller, thereby preventing the staff from accidentally starting the moving mold.

A moving block 17 is slidably installed on the inner side of the mold 4, a connecting rod 20 is fixed on the top of the moving block 17, a hinged rod 21 is hinged on the top of the connecting rod 20, and the end of the hinged rod 21 away from the connecting rod 20 is hinged on the slide rod 16, and a plurality of groups of knocking columns 22 in a linear array are fixed to the side wall of the moving block 17, and the side wall of the knocking column 22 is fitted with the inner side of the side wall of the movable mold 4, and a return spring 18 is fixed to the side wall of the moving block 17, and the side of the return spring 18 away from the moving block 17 is fixed to the inner side of the movable mold 4.

[0031] By setting up multiple groups of knocking columns 22, before the demolding operation is performed, the knocking columns 22 can be used to knock the inner side of the right side of the movable mold 4, so that the workpiece on the movable mold 4 can be knocked loose before demolding the workpiece, which is convenient for the subsequent demolding operation.

[0032] Two groups of demoulding columns 9 are provided, and the two groups of demoulding columns 9 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis, and the workpiece on the movable mold 4 can be ejected by the demoulding columns 9, so that the demoulding operation can be performed.

[0033] When the present embodiment is working, when the injection molding operation is required, the switch button on the controller 8 is used to start the cylinder 3, so that the cylinder 3 drives the movable mold 4 to approach the static mold 5, so that the convex part of the movable mold 4 extends into the mold groove of the static mold 5, and the injection liquid is poured into the mold groove of the static mold 5 through the injection tube 7, so as to start the injection molding operation. After the injection molding, the movable mold 4 is driven to move to the right by the cylinder 3, so that the movable mold 4 drives the push block 11 to move. When the push block 11 moves When the push block 11 comes into contact with the fixed plate 6, and when the push block 11 moves, because the elastic coefficient of the return spring 13 is larger than the elastic coefficient of the connecting spring 12, when the push block 11 is subjected to the extrusion force, the sleeve rod 10 will first move toward the demoulding column 9 to compress the connecting spring 12, and when the sleeve rod 10 moves, the arc block 15 can squeeze the top arc of the transmission block 19, and the elastic coefficient of the return spring 18 is smaller than the elastic coefficient of the connecting spring 12, when the transmission block 19 is subjected to the extrusion force, The transmission block 19 moves downward, causing the slide bar 16 to move downward, so that the slide bar 16 can squeeze the hinged rod 21 to rotate at the hinge, so that the hinged rod 21 can squeeze the connecting rod 20 to move, so that the moving block 17 can drive the knocking column 22 away from the right inner side of the movable mold 4, so that the moving block 17 squeezes the return spring 18 to stretch, and when the arc block 15 moves to not contact the top of the transmission block 19, because the return spring 18 is in a stretched state, the moving block 17 can drive the knocking column 22 to the movable mold 4 moves to the inner side of the right side of the movable mold 4 and knocks the inner side of the movable mold 4, so that the workpiece adhered to the movable mold 4 can be knocked loose, and when the sleeve rod 10 continues to move, when the connecting spring 12 is compressed to the complete state, so that when the sleeve rod 10 continues to move, the sleeve rod 10 can squeeze the connecting spring 12 to move, so that the connecting spring 12 drives the demoulding column 9 to move, so that the stopper 14 squeezes the reset spring 13 to be compressed, and the demoulding column 9 can move from the left side of the movable mold 4, so that the demoulding operation can be performed.

[0034] When the cylinder 3 drives the dynamic mold 4 to approach the static mold 5, it will drive the push block 11 away from the fixed plate 6. Since the sleeve rod 10 is not subjected to the extrusion force and the connecting spring 12 is in a compressed state, the sleeve rod 10 can be driven to move out of the demoulding column 9 for resetting. When the demoulding column 9 is not subjected to the extrusion force, the reset spring 13 is in a compressed state, so that the demoulding column 9 can be reset by the reset spring 13 for the next demoulding operation.

[0035] See also Figure 1-Figure 10On the basis of the above embodiment, another embodiment of the present invention further includes a centering component and a control component, wherein the centering component includes a fixing rod 2301, a fixing block 2302, a C-shaped rod 2303, a slide plate 2304, a slide groove 2305, an L-shaped connecting rod 2306, a connecting seat 2307, a connecting column 2308, a baffle 2309, a positioning plate 2311, a transmission spring 2310, an L-shaped limiting rod 2312, a hinge seat 2313, an extrusion plate 2315, a torsion spring 2314 and a limiting Hole 2316; the fixed rod 2301 is fixed to the top of the demoulding column 9, the top of the fixed rod 2301 is fixed with a fixed block 2302, the side wall of the fixed block 2302 is fixed with a C-shaped rod 2303, the right side of the movable mold 4 is slidably mounted with a slide plate 2304, the slide plate 2304 is provided with a slide groove 2305, the C-shaped rod 2303 penetrates the slide groove 2305, and the penetration is fitted, the side wall of the slide plate 2304 is fixed with an L-shaped connecting rod 2306, and the end of the L-shaped connecting rod 2306 is away from the slide plate 2304 A connecting seat 2307 is fixed, an L-shaped connecting rod 2306 penetrates the movable mold 4, and the L-shaped connecting rod 2306 can move at the penetration point of the movable mold 4, a connecting column 2308 penetrates the connecting seat 2307, and the penetration point is slidably connected, a baffle 2309 is fixed to the top of the connecting column 2308, a transmission spring 2310 is fixed to the bottom of the baffle 2309, and the bottom of the transmission spring 2310 is fixed to the top of the connecting seat 2307, and a positioning plate 2311 is fixed to the bottom of the connecting column 2308.

An L-shaped limiting rod 2312 is fixed to the side wall of the baffle 2309, and the outer wall of the L-shaped limiting rod 2312 fits with the inner side of the limiting hole 2316.

[0036] There are two groups of positioning plates 2311, and the two groups of positioning plates 2311 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis. By bringing the two groups of positioning plates 2311 close to each other, the two groups of positioning plates 2311 can just fit with the workpiece demolded from the movable mold 4, so that the workpiece can be centered, making it convenient for the staff to take it.

[0037] There are two groups of extrusion plates 2315, and the two groups of extrusion plates 2315 are symmetrically arranged with the center line of the movable mold 4 in the vertical direction as the symmetry axis. The extrusion plates 2315 can be used to extrude workpieces with relatively large burrs, and the rotation of the extrusion plates 2315 can prevent the staff from taking the problematic workpiece from the front of the equipment, and can remind the staff to repair the mold.

Through the setting of the block 2401, when there is a problem with the mold, the block 2401 can be stuck into the control switch button, so that the switch button cannot be pressed, so that the cylinder 3 will not start, to prevent the mold from having problems and the movable mold 4 from starting, which will cause serious product accidents.

[0039] When this embodiment is working: when the demoulding column 9 is squeezed to perform the demoulding operation, the demoulding column 9 can drive the fixed rod 2301 to move, so that the fixed block 2302 drives the C-shaped rod 2303 to move in the slide groove 2305 of the slide plate 2304, and when the C-shaped rod 2303 moves in the inclined groove section of the slide groove 2305, the slide plate 2304 will be squeezed and move downward, so that the L-shaped connecting rod 2306 can be driven to move, so that the L-shaped connecting rod 2306 drives the connecting seat 2307 and the connecting column 2308 to move, so that the two groups of positioning plates 2311 can be close to each other, so that the two groups of positioning plates 2311 and the demoulding column 9 can be demoulded. The top and bottom of the workpiece are fitted with the two sets of positioning plates 2311, so that the positioning plates 2311 fit exactly with the workpiece, the workpiece is centered, and the workpiece can be prevented from falling during demoulding. When the mold is used for a long time, the burrs of the workpiece produced may be too large. When the burrs of the workpiece produced are too large, the positioning plates 2311 and the workpiece will not fit together. When the two sets of positioning plates 2311 are close to each other, the positioning plates 2311 will squeeze the burrs of the workpiece, so that the positioning plates 2311 will be squeezed, and the positioning plates 2311 will move toward the connecting seat 2307 to make the transmission spring 2 310 is stretched, and the connecting column 2308 drives the baffle plate 2309 away from the connecting seat 2307, so that the baffle plate 2309 drives the L-shaped limiting rod 2312 to move upward, and the L-shaped limiting rod 2312 is moved out of the limiting hole 2316, so that the limiting of the extrusion plate 2315 can be released, and because the torsion spring 2314 is originally in a contracted state, the torsion spring 2314 can drive the extrusion plate 2315 to rotate, so that the extrusion plate 2315 can extrude the workpiece with a problem in demolding, and through the rotation of the extrusion plate 2315, the place where the staff at the front of the equipment take the material can be blocked, thereby preventing the staff from taking the material, and can It is enough to remind the staff to repair the mold, and when the movable mold 4 drives the extrusion plate 2315 to move, the extrusion plate 2315 can squeeze the baffle 2403 to move, so that the extrusion plate 2315 drives the baffle 2403 to move at the bottom of the block 2401, and when the extrusion plate 2315 rotates, the extrusion plate 2315 can stop squeezing the disc 2404, and because the fixed spring 2402 is in a stretched state, the fixed spring 2402 drives the block 2401 to move downward, so that the block 2401 is stuck in the switch button on the controller 8, so that the switch button cannot be pressed, so that the cylinder 3 will not start.

[0040] When the workpiece with problems is taken out, because the positioning plate 2311 is not in a squeezed state and the transmission spring 2310 is in a stretched state, the L-shaped limit rod 2312 will be pressed against the outer wall of the extrusion plate 2315. By rotating the extrusion plate 2315 to reset it so that the extrusion plate 2315 and the connecting seat 2307 are in a horizontal state, the limit hole 2316 can be aligned with the L-shaped limit rod 2312. Because the transmission spring 2310 is in a stretched state, the L-shaped limit rod 2312 can be extended into the limit hole 2316. Because the center of the limit hole 2316 is aligned with the center of the rotation of the extrusion plate 2315, when the L-shaped limit rod 2312 is extended into the limit hole 2316, the extrusion plate 2315 is fixed so that the next extrusion operation can be carried out, and when the extrusion plate 2315 rotates upward, the notch of the extrusion plate 2315 will be aligned with the baffle 2403, so that the baffle 2403 will pass through the notch of the extrusion plate 2315, and when the extrusion plate 2315 rotates to contact the bottom of the disc 2404, the extrusion plate 2315 squeezes the disc 2404 to move upward, so that the baffle 2403 can move upward, and the baffle 2403 drives the block 2401 to move upward, so that the fixing spring 2402 is stretched, so that the block 2401 does not jam the switch button on the controller 8, and when the extrusion plate 2315 is fixed, the disc 2404 can be fixed.
