Description

Technical Field

[0001] The utility model relates to the technical field of brick making, and particularly relates to a die matching machine for molds. Background Art

[0002] As a main material in the building materials industry, block bricks are produced by using a block forming machine in cooperation with corresponding molds. The product features are diverse, and it is impossible to design and produce all the molds at the time of equipment factory shipment and perform die matching and debugging on the equipment. Often, when the equipment is already in operation and the customer has new requirements, the mold is made. After the mold is produced, it needs to be die-matched in the mold factory and then sent to the customer.

[0003] The traditional die matching method is as follows: Invert the press head on the workbench, use a crane to lift the mold frame through a chain, put the mold frame on the press head, and perform up and down lifting actions through the crane to check the fit between the press head platen and the mold frame cavity. This die matching method has a defect: Since the chain is a flexible connection, if there is a slight mold jamming during die matching, there will be no mold jamming during die matching inspection. However, when the mold is sent to the site, since the block forming machine is guided by guide columns, when there is a slight mold jamming between the press head and the mold frame, due to the inability to yield, the situation of mold jamming between the press head and the mold frame will be reflected at the site. After this situation occurs, the die matching needs to be readjusted on site. If the on-site die matching adjustment is not successful, it needs to be sent back to the mold factory for re-die matching, which affects the customer's product production and increases the cost of the mold factory at the same time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a die matching machine for molds, which can simulate on-site operation of the mold, timely detect the phenomena of mold jamming and scraping, and the die matching speed is controllable.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The die matching machine for molds includes a frame, a guide column assembly, an electric hoist, a mold frame assembly for placing the mold frame, and a press head assembly for installing the press head, which are arranged on the frame. The mold frame assembly is arranged at the lower part of the frame. The press head assembly is located on the frame directly above the mold frame assembly, and the press head assembly is slidably matched with the guide column assembly. The electric hoist is installed on the frame above the press head assembly, and its lower hook is connected to the top of the press head assembly.

[0007] Further, the press head assembly includes an upper press frame and a slide rail installed and fixed at the bottom of the upper press frame, and the lower hook is connected to the upper press frame.

[0008] Further, the slide rail is detachably installed on the upper press frame through a movable hanger, and the installation position of the slide rail on the upper press frame is adjustable. The movable hanger is slidably matched with the slide rail.

[0009] Furthermore, the upper pressing frame includes a left beam, a right beam, a front beam, a rear beam and a middle beam. The left beam, the front beam, the right beam and the rear beam are sequentially connected by connecting pieces to form a rectangular frame. The middle beam spans above the rectangular frame and the center of gravity of the rectangular frame lies on the middle beam. The lower hanging hook is connected to the position of the middle beam corresponding to the center of gravity of the rectangular frame.

[0010] Furthermore, there are four groups of guide post assemblies, and the four groups of guide post assemblies are respectively arranged at the four columns of the machine frame. The upper pressing frame is slidably matched with the four groups of guide post assemblies through four slider assemblies.

[0011] Furthermore, each slider assembly respectively includes a slider, a positioning plate and a connecting frame. One end of the connecting frame is fixedly installed on the edge of the upper pressing frame, and the other end of the connecting frame is provided with a slider through the positioning plate. The slider is slidably matched with the guide post assembly.

[0012] Furthermore, the die frame assembly includes two support plates and two groups of adjusting cushion tubes. The two support plates are installed on the machine frame and the installation height of the support plates and the machine frame is adjustable. The two groups of adjusting cushion tubes are symmetrically installed on the top of the support plates, and the adjacent ends of the two groups of adjusting cushion tubes extend out of the support plates in opposite directions. The installation position of the adjusting cushion tubes and the support plates is adjustable.

[0013] Furthermore, the die matching machine further includes a synchronization assembly. The synchronization assembly includes a synchronization seat vertically fixed on the top of the pressing head assembly parallel to the guide post assembly, a synchronization shaft horizontally rotatably arranged on the machine frame, and synchronization gears respectively fixedly installed at both ends of the synchronization shaft. One side of the synchronization seat facing the synchronization gear has a synchronization rack, and the synchronization gear meshes with the synchronization rack on the corresponding side.

[0014] Furthermore, the die matching machine further includes two sets of safety assemblies. The safety assemblies include a cylinder seat fixedly installed on the machine frame, a cylinder hingedly installed on the cylinder seat, a movable hanging hook hinged to the end of the piston rod of the cylinder, and a toothed plate fixedly installed on the synchronization seat and having multiple upper and lower tooth-shaped grooves. The movable hanging hook is movably connected to the cylinder seat, and the hook head of the movable hanging hook abuts against a tooth-shaped groove of the toothed plate when the cylinder is in the locked working state.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The die matching machine of the present utility model includes a die frame assembly, a punch head assembly and an electric hoist arranged on a frame. During die matching, it can simulate the on-site operation effect of the punch head and the die frame when the block forming machine makes bricks. The punch head is installed on the punch head assembly, and the die frame is placed on the die frame assembly. The electric hoist drives the punch head assembly and the punch head thereon to move up and down. The electric hoist has a stable lifting, and has fast and slow functions, so that the die matching speed can be controlled. At the same time, compared with the hydraulic cylinder drive, the electric hoist has two advantages. First, when there is a problem of die jamming, since only the self-weight of the punch head exists, it will not cause external force extrusion damage to the die frame and the punch head. Second, there will be no phenomenon of the punch head squeezing and pushing the die frame to cause displacement and unable to reflect the die scraping during die matching.

Detailed implementation mode

[0028] In order to make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0029] As Figures 1-10 shown, this embodiment provides a mold matching machine, including a frame 100, a guide post assembly 200 arranged on the frame 100, an electric hoist 500, a mold frame assembly 300 for placing a mold frame, and a punch head assembly for installing a punch head. The mold frame assembly 300 is arranged at the lower part of the frame 100, and the punch head assembly is located on the frame 100 directly above the mold frame assembly 300 and the punch head assembly is slidably matched with the guide post assembly 200.

[0030] In this embodiment, the mold frame assembly 300 includes two support plates 31 and two groups of adjusting pad tubes 32. The two support plates 31 are installed on the frame 100 and the installation height of the support plates 31 and the frame 100 is adjustable. Specifically, a plurality of installation holes are arranged at intervals up and down at the lower part of the columns of the frame 100. Fixed holes are opened at the positions of the support plates 31 corresponding to the columns. The support plates 31 and the frame 100 are fixed by passing a pin through the fixed holes and the installation holes at the appropriate height. The two groups of adjusting pad tubes 32 are symmetrically installed on the top of the support plates 31 and the adjacent ends of the two groups of adjusting pad tubes 32 extend out of the support plates 31 in opposite directions. The installation position of the adjusting pad tubes 32 and the support plates 31 is adjustable. Specifically, a plurality of fastening holes are arranged at intervals in the left - right direction on the support plates 31. Matching holes are opened on the adjusting pad tubes 32. The adjusting pad tubes 32 are fixed on the support plates 31 and the distance between the two adjusting pad tubes 32 is adjusted by passing fasteners through the matching holes and the fastening holes to complete the adjustment of the width of the support surface to match mold frames of different specifications. When matching molds, the mold frame is placed on the mold frame assembly 300.

[0031] In this embodiment, the indenter assembly includes an upper pressing frame and a slide rail 42. The upper pressing frame includes a left side beam 411, a right side beam 412, a front side beam 413, a rear side beam 414 and a middle beam 415. The left side beam 411, the front side beam 413, the right side beam 412 and the rear side beam 414 are sequentially connected by connectors 416 to form a rectangular frame. The middle beam 415 spans above the rectangular frame and the center of gravity of the rectangular frame is on the middle beam 415. Among them, the front side beam 413 and the rear side beam 414 are I-shaped steel materials.

[0032] The slide rail 42 is detachably installed on the upper pressing frame through a movable hanger 43, and the installation position of the slide rail 42 on the upper pressing frame is adjustable. The movable hanger 43 is slidably fitted on the slide rail 42. Specifically: both ends of the slide rail 42 respectively extend out of the front side beam 413 and the rear side beam 414. The slide rail 42 is arranged perpendicular to the front side beam 413 and the rear side beam 414. One slide rail 42 cooperates with two movable hangers 43. The movable hangers 43 slide in the front-back direction along the slide rail 42, and in the die matching working state, the two movable hangers 43 are respectively hung on the front side beam 413 and the rear side beam 414, and the installation position of the slide rail 42 on the front side beam 413 and the rear side beam 414 can also be adjusted left and right. Before installing the indenter, the fixed relationship between the movable hanger 43 and the upper pressing frame is released. At this time, the movable hanger 43 can slide along the slide rail 42 and remain on the slide rail 42 without falling off; when the slide rail 42 is inserted into the slot at the top of the indenter and the indenter is moved below the upper pressing frame, then slide one of the movable hangers 43 to the front side beam 413, and use a fastening screw to tightly lock the movable hanger 43 on the slide rail 42 and the front side beam 413 and lock the movable hanger 43 to the indenter. Then move the other movable hanger 43 to the rear side beam 414 and perform the same operation to lock the movable hanger 43 on the slide rail 42 and the rear side beam 414 and lock the movable hanger 43 to the indenter, so as to install the indenter on the indenter assembly. After the die matching is completed, the indenter can be removed by operating in the reverse direction. To improve versatility, in this embodiment, the slide rail 42 can be matched with multiple groups, such as 2 groups (two groups of slide rails 42 are shown on the upper pressing frame in the figure). Two in a group, and only one group is used during die matching. One group is suitable for the indenter with an airbag locking structure, and the other group is suitable for the indenter with a bolt locking structure.

[0033] The movable hanger 43 includes a sliding part slidably fitted on the slide rail 42, an upper hanging part located on one side of the top of the sliding part, and a lower locking part located on the other side of the bottom of the sliding part. The upper hanging part cooperates with a fastener to hang on the side strips of the front side beam 413 and the rear side beam 414, and the lower locking part cooperates with a fastener to lock and install the die matching indenter.

[0034] In this embodiment, there are four sets of guide post assemblies 200, and the four sets of guide post assemblies 200 are respectively arranged at the four columns of the frame 100. The upper pressing frame is slidably fitted to the four sets of guide post assemblies 200 through four slider assemblies. Each slider assembly respectively includes a slider 45, a positioning plate and a connecting frame 44. One end of the connecting frame 44 is fixedly installed on the edge of the upper pressing frame, and the other end of the connecting frame 44 is provided with a slider 45 through the positioning plate. The slider 45 is slidably fitted to the guide post assembly 200. The guide post assembly 200 can ensure the linearity of the lifting of the pressing head assembly, limit the horizontal offset of the pressing head assembly, and overcome the defect that the clamping die phenomenon caused by the horizontal movement of the flexible chain in the conventional gantry crane die matching method cannot be detected in time.

[0035] In this embodiment, the electric hoist 500 is installed on the frame 100 above the pressing head assembly. Specifically, a fixed frame is arranged across the top of the frame 100. An ear seat 11 is provided at the position of the fixed frame corresponding to the electric hoist 500. The upper hook 51 of the electric hoist 500 is hung on the ear seat 11, and the lower hook 52 of the electric hoist 500 is connected to the position corresponding to the center of gravity of the rectangular frame of the middle beam 415. In this way, the lifting control of the pressing head assembly and the pressing head can be realized through the electric hoist 500, and the lifting is stable, and it has fast and slow functions.

[0036] In addition, to ensure the balance during the lifting of the pressing head so that the pressing head is parallel to the mold frame, the mold matching machine of this embodiment further includes a synchronization assembly. The synchronization assembly includes a synchronization seat 61 fixedly installed on the top of the upper pressing frame vertically and parallel to the guide post assembly 200, a synchronization shaft 62 horizontally rotatably arranged on the frame 100, and synchronization gears 63 respectively fixedly installed at both ends of the synchronization shaft 62. The two synchronization seats 61 are respectively arranged in the middle of the left side beam 411 and the middle of the right side beam 412. The synchronization shaft 62 is parallel to the front side beam 413. One side of the synchronization seat 61 facing the synchronization gear 63 has a synchronization rack 64. The synchronization gear 63 meshes with the synchronization rack 64 on the corresponding side. In this way, when the upper pressing frame is lifted or lowered, it will drive the synchronization seat 61 to lift or lower, and the lifting or lowering action of the synchronization seat 61 will drive the synchronization gear 63 meshing with it to rotate, so as to realize the synchronous lifting or lowering of each part of the upper pressing frame and keep it parallel.

[0037] Furthermore, the mold matching machine of this embodiment further includes two sets of safety components. The safety components include a cylinder seat 71 fixedly installed on the frame 100, a cylinder 72 hingedly installed on the cylinder seat 71 through a hinge seat, a movable hook 73 hinged to the end of the piston rod of the cylinder 72, and a toothed plate 74 fixedly installed on the synchronous seat 61 and having multiple upper and lower tooth-shaped grooves. The movable hook 73 passes through the shaft on the cylinder seat 71 and is movably connected to the cylinder seat 71, and the hook head of the movable hook 73 abuts against one tooth-shaped groove of the toothed plate 74 when the cylinder 72 is in the locked working state. When the upper pressure frame stops, the cylinder 72 is started to be in the constant ventilation state, so that the movable hook 73 moves towards the toothed plate 74 and enters the tooth-shaped groove to lock the toothed plate 74 and maintain the position, which can also prevent the upper pressure frame from falling due to the breakage of the electric hoist 500 or the chain, playing a safety protection role. Since the stop position of the upper pressure frame is random, the hook head may not all enter the tooth-shaped groove at this time, but when the upper pressure frame slides downward, the cylinder 72 in the constant ventilation state will cause the movable hook 73 to continue to rotate until the hook head completely enters the tooth-shaped groove.

[0038] The working process of the mold matching machine of this embodiment is as follows: Select a set of slide rails 42 according to the structure of the press head and remove the other sets of slide rails 42. Move the press head below the upper pressure frame, slide the movable hanger 43 to the front beam 413 and the rear beam 414 and lock the movable hanger 43 to the press head and keep the relative position between the movable hanger 43 and the upper pressure frame, and then lock and fix to realize the hanging of the press head and keep it fixed on the upper pressure frame; Adjust the installation height and the width of the support surface of the mold frame assembly 300 according to the mold frame specifications, and place the mold frame on the mold frame assembly 300; Then control the electric hoist 500 to lower the press head for mold matching inspection. If there is a mold jam, stop and ventilate the cylinder 72 to lock the upper pressure frame to maintain the position; After the mold matching is completed, the safety component is unlocked, and the electric hoist 500 is controlled to drive the press head to rise, and the press head and the mold frame are removed.
