Description

Technical Field

[0001] The invention belongs to the technical field of injection molding machines, and particularly relates to a two-platen injection molding machine mold clamping structure with a Green column extraction function. Background Art

[0002] The mainstream two-platen machine structure on the market currently uses Green rods to achieve mold locking during the mold closing process, and the Green rods need to be pulled out when the mold is placed. Figure 1 As shown, the fixed plate 100 is fixed on the base of the fuselage, the mold-moving cylinder 500 is placed diagonally between the fixed plate 100 and the movable plate 200, the clamping cylinder 40 is fixed on the fixed plate 100, one end of the Green column 300 is built into the clamping cylinder 40, and the other end passes through the movable plate 200 and cooperates with the half brake nut 50; one end of the pull rod bracket 700 is fixed to the top of the fixed plate 100, and the other end is fixed to the ground through the support frame 900, one end of the pull column cylinder 431 is fixed on the pull rod bracket 700, and one end is fixedly connected to the clamping cylinder 40, and the hydraulic clamp 800 is fixed to the fixed plate 100. Under normal working conditions, the column extraction cylinder 431 moves to the bottom in the direction of the movable plate 200 until the clamping cylinder 40 sticks to the fixed plate 200, and the hydraulic clamp 800 clamps the clamping cylinder 40 and drives the mold-moving cylinder 40 to make the movable plate 200 reach the specified position. After the clamping cylinder 40 adjusts the position of the Green column 30, the half brake nut 50 clamps the Green column 30, and the clamping cylinder 40 generates high pressure to lock the mold; when the mold needs to be changed, the hydraulic clamp 800 is released, and the column extraction cylinder 431 is driven to pull out the clamping cylinder 40 and the Green column 30 until the Green column 30 enters the large plane of the fixed plate 100.

[0003] However, there are the following problems: because the Green column is built into the clamping cylinder, it must be pulled in and out together with the clamping cylinder when the Green column is withdrawn. The entire mechanism is relatively heavy, and a pull-out rod bracket needs to be installed above the fixed platen. The pull-out rod bracket mechanism must be safe and reliable enough. Because the pull-out rod bracket is in a cantilever beam state, a support needs to be installed at the other end of the pull-out rod bracket. The entire pull-out rod mechanism takes up a lot of space, which causes a lot of inconvenience to the arrangement of other components of the injection molding machine and also has certain requirements on the height of the customer's factory building; because the Green column is pulled in and out together with the clamping cylinder, it is very heavy, and the speed of pulling out the pull rod will be relatively slow, affecting the customer's mold changing efficiency; the mold shifting cylinder is placed between the movable platen and the fixed platen, distributed diagonally. The mold shifting cylinder above will affect the robot's removal of parts, and the mold shifting cylinder below will increase the hidden danger to the safety protection of the injection molding machine; there will be many water-oil devices between the movable platen and the fixed platen, and some mold products will also use mold drag agents. The working conditions are relatively harsh, which increases the risk of oil leakage in the mold shifting cylinder. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0037] Please refer to Figure 2-3 The present invention discloses a two-platen injection molding machine mold clamping structure with a Green column extraction function, comprising:

[0038] The fixed template 100 and the movable template 200 are arranged on one side of the fixed template 100, and the movable template 200 can move toward or away from the side of the fixed template 100. The movable template 200 opens the mold toward the side away from the fixed template 100, and closes the mold toward the side close to the fixed template 100.

[0039] The clamping mechanism includes a lower clamping assembly 300 and an upper clamping assembly 400. The upper clamping assembly 400 is located above the lower clamping assembly 300. The upper clamping assembly 400 is used to clamp the upper part of the movable template 200 and the fixed template 100, and the lower clamping assembly 300 is used to clamp the lower part of the movable template 200 and the fixed template 100. The two work together to perform the clamping action.

[0040] Preferably, the lower mold clamping assembly 300 includes at least two first Green columns 310 arranged in parallel and a first mold clamping member fixed to the movable mold plate 200. One end of the two first Green columns 310 are fixedly connected to the lower part of the fixed mold plate 100, and the other end of the two first Green columns 310 are fixedly connected to the fixed connecting plate. The lower part of the movable mold plate 200 is movably sleeved on the first Green columns 310. The first mold clamping member can tighten / release the first Green columns 310. The first One end of the Green column 310 is fixed on the fixed template 100, and the other end is fixed to the body of the injection molding machine through a connecting plate, that is, the first Green column 310 is fixed. During the opening and closing process of the movable template 200, the first Green column 310 can play a guiding role. When the movable template 200 is closed in place, the first clamping component holds the first Green column 310 tightly. At this time, the movable template 200 can no longer move, realizing the clamping of the lower part of the movable template 200. When the mold needs to be opened, the first clamping component releases the first Green column 310.

[0041] Preferably, the upper clamping mold assembly 400 includes at least two second Green columns 410, a second clamping mold part fixed on the movable template 200, and a column extraction part 430, one end of the two second Green columns 410 can be detachably connected to the upper part of the fixed template 100, the upper part of the movable template 200 is movably sleeved on the two second Green columns 410, the second clamping mold part can hold / release the second Green columns 410, and the column extraction part 430 is used to drive the second Green columns 410 to move away from / close to the side of the movable template 200, that is, the second Green column 410 can be fixedly connected to the fixed template 100 and can be separated from it. During the mold closing process, the second Green column 410 is inserted into the fixed template 100 and fixedly connected to the fixed template 100. At this time, the second clamping mold part The mold clamps the second Green column 410 to prevent the movable template 200 from continuing to move. During the mold opening process, the second mold locking component releases the second Green column 410, and the second Green column 410 is separated from the fixed template 100. First, the mold shifting cylinder 500 drives the movable template 200 to move to the side away from the fixed template 100, and the second Green column 410 also moves with the movable template 200. After the movable template 200 moves to the maximum mold opening distance, the column extraction component 430 drives the second Green column 410 to continue to move to the side away from the fixed template 100 until the second Green column 410 does not hinder the entry of the mold. The mold can be replaced by a robot. The overall weight of the two second Green columns 410 is low. When driving them to move, there is no need to set up a column extraction support frame 900, which reduces the occupied space and is suitable for factories with limited space.
