Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of molding machines, and in particular relates to an installation mechanism for assembling a molding cavity of a molding machine. Background Art
[0002] Molding machines are divided into horizontal molding machines and vertical molding machines. Vertical molding machines mainly process products that require inserts, while horizontal molding machines mainly process products that do not require inserts. That is, vertical molding machines process secondary molding products, and horizontal molding machines process primary molding products.
[0003] Among them, the horizontal molding machine is divided into two parts, the moving side and the fixed side. The moving side and the fixed side are connected by a guide column. The fixed side is used to fix the cavity (fixed mold), and the moving side is used to fix the movable mold. After the moving side is close to the fixed side, the fixed mold and the movable mold can be combined into one piece.
[0004] At present, the cavity assembly structure of the horizontal molding machine includes a movable mold fixed on the movable side and a cavity fixed on the fixed side, wherein both the fixed side and the movable side are provided with horizontally and vertically arranged linear grooves, and the movable mold and the cavity are respectively fixed to the corresponding fixed side and movable side by the cooperation of the linear grooves and bolts.
[0005] In the above technical solution, the cavity and the movable mold are fixed by the cooperation of bolts and linear grooves. Although this method can fix molds of various specifications, in the process of fixing the mold, it is necessary to manually fix the bolts at the four corners of the movable side or the fixed side in turn, and due to the large weight and volume of the mold, it is cumbersome and difficult to quickly replace the mold, resulting in a long downtime period for the molding machine production. Utility Model Content
[0006] In order to solve the technical problem in the prior art that manually fixing a mold with a large weight and volume is cumbersome and complicated and takes too long a working time, the utility model provides an installation mechanism for assembling a mold cavity of a molding machine.
[0007] The purpose of the utility model can be achieved through the following technical solutions:
[0008] A mounting mechanism for assembling a cavity of a molding machine, comprising a fixing part for fixing the cavity mold;
[0009] The moving part fixes the movable mold;
[0010] A guide post is connected to the fixed part, and the movable part is slidably arranged on the guide post;
[0011] A pressure block is provided at a position in the middle and lower part of a side of the fixed part close to the movable part for vertical movement; a folding rod is slidably provided on the pressure block; a fixed rod is fixedly provided on the fixed part and the movable part corresponding to the bending part of the folding rod; a hinge rod is fixedly connected to the upper end of the folding rod; a hinge block is rotatably connected to the hinge rod; a clamp block is fixedly connected to the end of the hinge block away from the hinge rod, and the clamp block presents an L-shaped structure;
[0012] The fixed part and the movable part are both fixedly connected with fixed blocks at positions corresponding to the positions below the pressing block; and dampers are both fixedly connected with the upper surfaces of the fixed blocks.
[0013] Furthermore, the pressing block is provided with a first straight groove with a hollow top and two ends; a second straight groove is provided inside the first straight groove;
[0014] A movable slider is fixedly connected to the lower end of the folding rod. The lower end of the folding rod is slidably connected in the first straight groove, and the movable slider is slidably connected in the second straight groove.
[0015] Furthermore, the fixed part and the movable part are provided with arc grooves corresponding to the positions of the moving track of the hinged rod, and the cross section of the arc groove is T-shaped; a limiting slider is fixedly connected to one end of the hinged rod close to the arc groove, and the limiting slider is slidably connected inside the arc groove.
[0016] Furthermore, a curved spring is arranged on the upper part of the folding rod, and two ends of the curved spring are respectively connected to the clamping block and the bending part of the folding rod.
[0017] Furthermore, the upper part of the folding rod is fixedly connected to a limit plate, which has an arc-shaped structure and a right-angle structure on a side close to the clamping block, and a cross section of the limit plate has a concave shape; the limit plate fits the curved spring.
[0018] Beneficial effects of the utility model:
[0019] The utility model uses the cooperation of the clamping block, the folding rod, the pressure block and the damper, and utilizes the downward force applied by the cavity mold to the pressure block and the folding rod to drive the clamping block to fix the two sides of the cavity mold. The installation operation can be completed after reaching balance. When disassembling, the cavity mold only needs to be slid upward, and it can be reset under the action of the damper. The disassembly operation is completed from then on, and the rapid installation and disassembly of the cavity mold and the self-centering clamping can be realized.
[0020] The utility model can make the clamp block maintain a vertical state with the upper end of the folding rod when not affected by external force through the cooperation of the curved spring and the limit plate, so that the operator does not need to adjust the angle of the clamp block when installing the cavity mold or the movable mold, which is faster and more convenient. In addition, by setting the limit plate as an arc structure and the side close to the clamp block as a right-angle structure, the deformation angle of the curved spring can be guided and the maximum movement angle of the clamp block can be limited, ensuring that the clamp block is always at the optimal angle when no force is applied; the limit plate with a concave cross-section can limit the position of the curved spring to avoid falling off.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figure 1As shown, an installation mechanism for assembling a cavity of a molding machine includes a fixed part 1, a movable part 2, and a guide column 3 connecting the fixed part 1 and the movable part 2; a cavity mold 4 is fixedly arranged on the fixed part 1, and a movable mold (not shown in the figure) is fixedly arranged on the movable part 2.
[0030] Please refer again Figure 1-Figure 3 As shown, a pressure block 5 is provided at a position in the middle and lower part of a side of the fixed part 1 close to the movable part 2, which can be moved up and down; a folding rod 6 is slidably provided on the pressure block 5; a first straight groove 501 with a hollow top and two ends is provided on the pressure block 5; a second straight groove 502 is provided inside the first straight groove 501; a movable slider 503 is fixedly connected to the lower end of the folding rod 6, and the lower end of the folding rod 6 is slidably connected in the first straight groove 501, and the movable slider 503 is slidably connected in the second straight groove 502.
[0031] Please refer again Figure 2 and Figure 4 As shown, a fixing rod 604 is fixedly provided on the fixed part 1 and the movable part 2 corresponding to the bending part of the folding rod 6, and the folding rod 6 is rotatably connected to the fixed part 1 or the movable part 2 through the fixing rod 604; a hinge rod 601 is fixedly connected to the upper end of the folding rod 6; a hinge block 603 is rotatably connected to the hinge rod 601; a clamping block 7 is fixedly connected to the end of the hinge block 603 away from the hinge rod 601, and the clamping block 7 is an L-shaped structure, which is used to cooperate with the pressure block 5 to fix the cavity mold 4 or the movable mold.
[0032] Please refer again Figure 2 and Figure 4 As shown, the fixed part 1 and the movable part 2 are provided with an arc groove 605 at the position corresponding to the moving trajectory of the hinged rod 601; the cross section of the arc groove 605 is T-shaped; one end of the hinged rod 601 close to the arc groove 605 is fixedly connected to a limiting slider 602, and the limiting slider 602 is slidably connected inside the arc groove 605 to prevent the folding rod 6 from being deformed due to force.
[0033] Please refer again Figure 4 As shown, the upper part of the folding rod 6 is fixedly connected to a limit plate 701, which has an arc-shaped structure and a right-angle structure on one side close to the clamping block 7, and a cross-section of the limit plate 701 has a concave shape; a curved spring 702 is movably arranged on the limit plate 701, and the two ends of the curved spring 702 are respectively connected to the clamping block 7 and the bending part of the folding rod 6, so as to prevent the clamping block 7 from sagging downward when it is not subjected to forces other than the curved spring 702.
[0034] Please refer again Figure 2 As shown, the fixed portion 1 and the movable portion 2 are fixedly connected with a fixed block 504 at positions corresponding to the positions below the pressing block 5 via reinforcing ribs; dampers 505 are fixedly connected with bolts on both sides of the upper surface of the fixed block 504, and the upper ends of the dampers 505 are connected to the pressing block 5.
[0035] When the cavity mold 4 or the movable mold is fixed, the cavity mold 4 or the movable mold is lifted by a crane, and then moved to the top of the fixed part 1 and the movable part 2 respectively, and dropped after aligning the position between the clamping block 7, and the pressing block 5 is pressed down by the weight of the cavity mold 4 itself. At this time, due to the downward movement of the pressing block 5, the corresponding upper part of the folding rod 6 moves inward synchronously under the restriction of the fixed rod 604, the first straight groove 501 and the second straight groove 502, until the clamping block 7 fits with the surface of the cavity mold 4 or the movable mold. At this time, the clamping block 7 can no longer move, and the folding rod 6 also prevents the pressing block 5 from moving downward. After reaching a balanced state, the self-centering clamping and fixing of the cavity mold 4 or the movable mold can be achieved;
[0036] When disassembling the cavity mold 4 or the movable mold, it can be quickly disassembled by directly lifting it from the inside of the clamp block 7 through a crane. In addition, the pressure block 5 rebounds under the action of the damper 505, causing the positions of the folding rod 6 and the clamp block 7 to be reset, and the clamp block 7 is kept in an open state, which is conducive to quickly replacing the cavity mold 4 or the movable mold. In addition, the setting of the damper 505 can also play a shock-absorbing role, and can provide a certain buffering effect when installing the cavity mold 4 or the movable mold to avoid damage.
[0037] Compared with the prior art, fast fixing and disassembly can be achieved without calibration and bolts, which greatly reduces the replacement time of the cavity mold 4 or the movable mold and shortens the downtime of the horizontal injection molding machine.
[0038] Through the cooperation of the curved spring 702 and the limit plate 701, the clamp 7 can maintain a vertical state with the upper end of the folding rod 6 when not affected by external forces, so that the operator does not need to adjust the angle of the clamp 7 when installing the cavity mold 4 or the movable mold, which is faster and more convenient. In addition, by setting the limit plate 701 to an arc structure and the side close to the clamp 7 to a right-angle structure, the deformation angle of the curved spring 702 can be guided and the maximum movement angle of the clamp 7 can be limited, ensuring that the clamp 7 is always at the optimal angle when not subject to force; the limit plate 701 with a concave cross-section can limit the position of the curved spring 702 to prevent it from falling off.
[0039] The upper part of the folding rod 6 can be supported and limited by the cooperation of the arc groove 605, the hinge rod 601 and the limiting slider 602, so that the clamping block 7 is always in contact with the surface of the fixed part 1 or the surface of the movable part 2, avoiding the clamping block 7 from falling off due to the force of the cavity mold 4.
