Description

Technical Field

[0001] This utility model relates to the field of mold blank transfer technology, specifically a mold blank transfer device for mold processing. Background Technology

[0002] In mold manufacturing workshops, mold blanks (also known as mold frames) are the skeleton of molds. They are responsible for installing all key components such as cores, cavities, guide pillars, and ejector pins. The weight of a standard mold blank can range from tens of kilograms to several tons. How to safely, efficiently, and accurately transfer these heavy and precise mold blanks between different processing equipment (such as CNC, deep hole drilling, EDM, grinding machines, and assembly areas) has become a core issue. Mold blank transfer devices were created to solve this problem.

[0003] Mold transfer devices are a general term for a series of mechanical and automated equipment used for handling, moving, positioning and storing mold blanks. There are many types of mold transfer devices. Among them, there is a mold transfer trolley (also known as a manual hydraulic lifting platform trolley), which includes a lifting platform, hydraulic cylinder, support frame, etc. It uses the hydraulic transmission principle to realize the lifting function. The lifting height is controlled by manually operating the hydraulic pump, which can meet the needs of transferring mold blanks on worktables at different heights.

[0004] During the process of transferring the mold blank using this mold blank transfer trolley, the mold blank placed on the platform needs to be positioned to avoid the mold blank shifting and sliding on the platform due to the inertia of movement, which could cause a safety accident. Based on this, a mold blank transfer device for mold processing is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a mold blank transfer device for mold processing in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold blank transfer device for mold processing, comprising a platform assembly consisting of a rectangular platform frame, a fixed side plate one-way limiting component, and support rollers. The fixed side plate one-way limiting component is symmetrically fixed to the top of both sides of the rectangular platform frame. Multiple support rollers are provided, and the multiple support rollers are evenly distributed along the long side of the rectangular platform frame and rotatably installed on the inner side of the rectangular platform frame via a rotating shaft. A one-way limiting component is installed on the inner side of the rectangular platform frame between two adjacent support rollers. The one-way limiting component is used to lock the mold blank on the top of the support roller in one direction.

[0007] The top end of the fixed side plate one-way limiting component is provided with an L-shaped guide groove, and the two sides of the fixed side plate one-way limiting component are provided with sealing components that extend through the L-shaped guide groove. The sealing components are used to seal one end of the two fixed side plate one-way limiting components and cooperate with the one-way limiting components to realize the limiting of the mold blank.

[0008] As a further embodiment of this utility model: the unidirectional limiting component includes an eccentric ratchet locking block, a connecting shaft, and a spacer ring block;

[0009] The eccentric ratchet locking block is distributed between two adjacent support rollers and is rotatably sleeved on the outside of the connecting shaft. The connecting shaft is fixedly connected to the rectangular platform frame. The bottom of the eccentric ratchet locking block is formed with a weight, one side of which contacts one support roller, and the other side of which does not contact the other support roller, so as to realize the unidirectional rotation of the eccentric ratchet locking block.

[0010] The top of the eccentric ratchet locking block has an arc-shaped protrusion on one side and a vertical plane on the other side. The vertical plane contacts the side of the mold blank to achieve unidirectional movement locking of the mold blank.

[0013] Two concave slides are provided. The two concave slides are respectively sleeved on the outside of the screw and the guide rail and are in contact with the outer wall of the fixed side plate one-way limiting component. The inner hole of the concave slide that contacts the screw is formed with an internal thread that matches the thread of the outer wall of the guide rail.

[0014] The hand-cranked worm gear reducer is installed on one side of the outer wall of the fixed side plate one-way limit assembly, and the output end of the hand-cranked worm gear reducer is fixedly connected to the screw. The operation of the hand-cranked worm gear reducer is used to drive the concave slide to move horizontally.

[0015] The limiting rod is engaged with the inner side of the two concave slides and horizontally passes through the two L-shaped guide grooves. The limiting rod is used to block one port of the one-way limiting assembly of the two fixed side plates. The limiting rod is in contact with the side of the mold blank to achieve one-sided limiting of the mold blank.

[0016] As a further improvement of this utility model: the limiting rod consists of a crossbar and a limiting block, the limiting block being symmetrically fixed on both sides of the crossbar, and the outer diameter of the crossbar matching the height of the horizontal groove of the L-shaped guide groove and the width of the concave slide.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4In this embodiment of the present invention, a mold blank transfer device for mold processing includes a platform assembly 1 consisting of a rectangular platform frame 101, a fixed side plate one-way limiting component 102, and support rollers 105. The fixed side plate one-way limiting component 102 is symmetrically fixed to the top of both sides of the rectangular platform frame 101. Multiple support rollers 105 are provided. The multiple support rollers 105 are evenly distributed along the long side of the rectangular platform frame 101 and are rotatably installed on the inner side of the rectangular platform frame 101 through a rotating shaft. A one-way limiting component 2 is installed on the inner side of the rectangular platform frame 101 between two adjacent support rollers 105. The one-way limiting component 2 is used to lock the mold blank on the top of the support roller 105 in one direction.

[0029] An L-shaped guide groove 103 is provided at one end of the top of the fixed side plate one-way limiting component 102. A sealing component 3 extending through the L-shaped guide groove 103 is provided on both sides of the fixed side plate one-way limiting component 102. The sealing component 3 is used to seal one end of the two fixed side plate one-way limiting components 102 and cooperates with the one-way limiting component 2 to realize the limiting of the mold blank.

[0030] One-way limiting component 2 includes an eccentric ratchet locking block 201, a connecting shaft 202, and a spacer ring block 203;

[0031] The eccentric ratchet locking block 201 is distributed between two adjacent support rollers 105 and is rotatably sleeved on the outside of the connecting shaft 202. The connecting shaft 202 is fixedly connected to the rectangular platform frame 101. The bottom of the eccentric ratchet locking block 201 has a weight formed, and one side of the weight is in contact with one support roller 105, while the other side of the weight is not in contact with the other support roller 105, so as to realize the unidirectional rotation of the eccentric ratchet locking block 201.

[0032] The eccentric ratchet locking block 201 has an arc-shaped protrusion on one side and a vertical plane on the other side. It contacts the side of the mold blank through the vertical plane to achieve unidirectional movement locking of the mold blank.

[0033] The sealing assembly 3 includes a screw 301, a guide rail 302, a bearing base 303, a concave slide 304, a hand-cranked worm gear reducer 305, and a limit rod 306;

[0034] Screws 301 and guide rails 302 are symmetrically distributed on the outside of the two fixed side plate one-way limiting components 102, and screws 301 and guide rails 302 are rotatably mounted on the outside of the fixed side plate one-way limiting components 102 through bearing bases 303. Screws 301 and guide rails 302 are distributed below the area where the L-shaped guide groove 103 is located.

[0035] Two concave slide blocks 304 are provided. The two concave slide blocks 304 are respectively sleeved on the outside of the screw 301 and the guide rail 302 and are in contact with the outer wall of the fixed side plate one-way limiting component 102. The inner hole of the concave slide block 304 in contact with the screw 301 is formed with an internal thread that matches the thread of the outer wall of the guide rail 302.

[0036] A hand-cranked worm gear reducer 305 is installed on one side of the outer wall of the fixed side plate one-way limit assembly 102, and the output end of the hand-cranked worm gear reducer 305 is fixedly connected to the screw 301. The operation of the hand-cranked worm gear reducer 305 is used to drive the concave slide 304 to move horizontally.

[0037] The limiting rod 306 is engaged with the inner side of the two concave slides 304 and horizontally passes through the two L-shaped guide grooves 103. The limiting rod 306 is used to block one port of the two fixed side plate one-way limiting components 102. The limiting rod 306 is in contact with the side of the mold blank to achieve one-sided limiting of the mold blank.

[0038] In this embodiment, it should be noted that when this platform component 1 is in use, the bottom of the rectangular platform 101 is installed on the mobile trolley via a hydraulic lifting system (such as a scissor-type hydraulic lifting system). The lifting and lowering of the platform component 1 can be achieved through the hydraulic lifting system to match processing platforms of different heights. The transfer of the mold blank can be achieved by moving the mobile trolley. This structure is an existing structure, so it will not be described in detail here.

[0039] The operating principle of this platform component 1 when transferring the mold blank is as follows:

[0040] In the initial state of platform component 1, the limiting rod 306 is engaged with the inner side of the two concave slides 304 and horizontally penetrates the two L-shaped guide grooves (e.g. Figure 1 / 2), at this time, by adjusting the moving trolley, one end of the opening of the two fixed side plates 102 is aligned with the processing platform and aligned with the position of the mold blank;

[0041] Afterwards, the mold blank is manually (or transferred via external hoisting equipment) onto the platform assembly. During this process, the mold blank moves along the upper surface of the support roller 105 and contacts the arc surface of the eccentric ratchet locking block 201. The mold blank applies a compressive force to the eccentric ratchet locking block 201, causing it to rotate around the connecting shaft 202. The top protrusion of the eccentric ratchet locking block 201 flips downward without obstructing the movement of the mold blank. When the mold blank moves away from the eccentric ratchet locking block 201, the eccentric ratchet locking block 201 will return to its upright position under the weight of the bottom weight block (e.g., Figure 1-4 Finally, the mold blank makes contact with the limiting rod 306;

[0042] When the mold blank contacts the limiting rod 306, there is a space for movement between the other side of the mold blank and a row of eccentric ratchet locking blocks 201 on its rear side. At this time, the handwheel on the input shaft of the hand-cranked worm gear reducer 305 is rotated to drive a concave slide 304 to move. The limiting rod 306 and another concave slide 304 are driven to move. The limiting rod 306 pushes the mold blank to move backward and fits against the vertical plane of the eccentric ratchet locking block 201 (it should be noted that at this time, the bottom weight of the eccentric ratchet locking block 201 is in contact with the support roller 105 and cannot rotate), thereby achieving the limiting of the mold blank.

[0043] In this way, during the subsequent transfer process, the displacement of the mold blank in the rotation direction of the support roller 105 due to the inertia of movement can be effectively avoided, and the safety factor of the mold blank movement can be effectively improved. (It should also be noted that the eccentric ratchet locking blocks 201 distributed on both sides of the mold blank and not in contact with the mold blank remain in an upright state, and have a certain movement limit function in the lateral direction of the mold blank.)

[0044] Please refer to this carefully. Figures 1-4 The limiting rod 306 consists of a crossbar 3061 and a limiting block 3062. The limiting block 3062 is symmetrically fixed on both sides of the crossbar 3061. The outer diameter of the crossbar 3061 matches the height of the horizontal groove of the L-shaped guide groove 103 and the width of the concave slide 304.

[0045] A magnetic block 307 is installed on the top of a bearing base 303 corresponding to the guide rail 302, and an iron block 308 is installed on the side of a concave slide 304 corresponding to the guide rail 302.

[0046] When the groove of the concave slide 304 is aligned with the vertical opening of the L-shaped guide groove 103, the magnetic block 307 and the iron block 308 are attached and attracted to each other.

[0047] The fixed side plate one-way limiting assembly 102 has a placement groove 104 at the top of the end away from the L-shaped guide groove 103. The vertical plane of the top protrusion of the eccentric ratchet lock block 201 faces the L-shaped guide groove 103, and the arc surface of the top protrusion of the eccentric ratchet lock block 201 faces the groove 104.

[0048] In this embodiment: when it is necessary to transfer the mold blank placed on platform component 1 to the working platform, the operation is as follows:

[0049] With one end of the two fixed side plates 103 blocked facing and close to the work platform, the hand-cranked worm gear reducer 305 is operated to move the concave slide 304 close to the vertical slot of the L-shaped guide groove 103. When the groove of the concave slide 304 is aligned with the vertical slot of the L-shaped guide groove 103, the limit rod 306 can be taken out and temporarily placed inside the placement groove 104.

[0050] At this point, the movement limit on the mold blank is released, and the mold blank can then be smoothly transferred to the work platform.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
