Description

Technical Field

[0001] The invention relates to the technical field of hand mold manufacturing, and in particular to a hand blank punching and shaping device for a metal hand mold and metal hand mold manufacturing equipment. Background Art

[0002] Glove molds are a type of mold used by glove factories to assist in glove dipping. Currently, glove molds are mainly divided into ceramic glove molds and metal glove molds. Metal glove molds are suitable for various PU, PVC, nitrile, latex, film and other glove processing fields. Because metal glove molds have higher structural strength and better temperature and heat dissipation performance than ceramic glove molds, they are more common in actual applications.

[0003] Metal glove molds are generally manufactured through a casting process. After the molten metal is introduced into the mold, the blank of the hand mold is obtained after cooling. Existing hand mold blanks generally include a left half of the hand mold, a right half of the hand mold (the left half of the hand mold and the right half of the hand mold do not correspond to the left and right hands, but refer to the two basic symmetrical components that constitute the hand mold, both including the arm, palm and finger parts) and a base. The two hand mold halves of the hand mold blank have excess metal at the fingertips and wrist positions of the fingers, and the fingers are generally connected to each other. The excess metal of the hand mold blank needs to be cut to obtain the final hand mold product. Due to the complexity of the hand mold structure, the cutting process is time-consuming and labor-intensive, and the efficiency is low, which increases the production cost of the hand mold, and thus a device for punching the hand mold blank has emerged.

[0004] During the welding process of the two hand model halves, the finger parts are difficult to weld and the weld seam is difficult to process, which results in a long welding time between the two hand model halves, high production costs, and also affects the quality of metal hand model products. Therefore, the applicant has developed a new type of metal hand model consisting of a hand blank (fingers and part of the hand) and an arm blank (arm and part of the hand). In production and manufacturing, only the left arm blank and the right arm blank need to be welded, without welding the hand blank with a more complex structure, which greatly improves the production efficiency of the hand model.

[0005] The removal method of the nozzle and runner of traditional die-casting products is directional punching. Because this method only punches part of the product, the edge of the product will have ups and downs and uneven thickness. If laser welding is performed on this type of product, the quality is very unsatisfactory. There will be sand holes, insufficient penetration, or perforation at the welding port, and the weld will be difficult to handle, which will increase the production cost and affect the quality of the metal hand mold product.

[0006] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0007] The existing hand mold blank punching and shaping device is not suitable for the production of new metal hand molds, which affects the efficiency of hand mold production and increases the production cost of the hand mold. Summary of the invention

[0040] In order to illustrate the technical solution of the present invention, a specific embodiment is used below for description, and only the parts related to the embodiment of the present invention are shown.

[0041] Embodiment 1:

[0042] like Figure 1-7As shown, the present invention provides a hand blank punching and shaping device for a metal hand mold, comprising a first auxiliary fixing component 1, a hand tool component 2, a second auxiliary fixing component 3 and a fastening component 4, wherein the first auxiliary fixing component 1 and the second auxiliary fixing component 3 are used to fix the hand blank 5, the fastening component 4 is used to enhance the fixing effect of the hand blank 5, and the hand tool component 2 is used to punch the hand blank 5, so as to facilitate obtaining the hand 51 for the subsequent hand mold manufacturing process. The first auxiliary fixing component 1, the hand tool component 2 and the second auxiliary fixing component 3 are sequentially detachably connected, which is convenient for the installation and disassembly of the present invention. The first auxiliary fixing component 1 and the second auxiliary fixing component 3 fix the hand tool component 2 on both sides, so that the hand tool component 2 is not easy to shake during the punching process, which is convenient for accurate punching. The hand tool component 2 matches the shape of the hand blank 5, which is convenient for the smooth completion of punching. The fastening component 4 is connected to the hand blank 5 and can fasten the hand blank 5, which is convenient for improving the punching quality and precision. The hand tool assembly 2 can punch and trim the hand blank 5 under the action of force to obtain the hand 51 of the metal hand mold. After the hand 51 and the arm are welded to each other, the finished metal hand mold can be obtained. The device for applying force to the hand tool assembly 2 can be a punching machine, a cylinder, an air hammer, etc. After the external force acts on the first auxiliary fixing assembly 1, the force is transmitted to the hand tool assembly 2, and the hand tool assembly 2 moves downward to achieve punching and trimming of the hand blank 5. The second auxiliary fixing assembly 3 achieves buffering during the punching process. The device for applying force can also restore the position of the hand tool assembly 2 after the punching is completed, so as to facilitate punching the next hand blank 5 again. The present invention can obtain a hand after a one-time punching of the hand blank 5 by the hand tool assembly 2, and is suitable for the production and manufacturing of new metal hand molds, which improves the efficiency of hand mold production and manufacturing and reduces the cost of hand mold production. At the same time, the first auxiliary fixing component 1 and the second auxiliary fixing component 3 fix the hand tool component 2 and the hand blank 5, and the fastening component 4 strengthens the fixation of the hand blank 5, ensuring the accuracy of the stamping and trimming position of the hand blank 5 and ensuring product quality.

[0043] As an optional implementation, Figure 8 As shown, the hand blank 5 includes a hand 51 and a slug 52. The hand 51 and the slug 52 are an integrally cast structure, and the slug 52 is punched when the hand blank 5 is punched. The slug 52 is an extra structure formed during the casting process of the hand blank 5 to facilitate the flow and molding of the molten metal, so it needs to be removed during the processing of the hand 51. After the slug 52 of the hand blank 5 is punched, it is attached to the hand 51, and then welded with the arm to obtain the final hand mold structure.

[0044] As an optional implementation, Figure 1-3As shown, the hand tool assembly 2 includes a cutting edge plate 21, a contour limiter 22, a clamping plate 23 and a tool which are connected in sequence, and the connection methods are all detachable connections to facilitate installation and disassembly. Specifically, the hand tool assembly 2 is connected to the first auxiliary fixing assembly 1 via the sixth connecting column 26, the cutting edge plate 21 and the clamping plate 23 are connected via the seventh connecting column 28, and the hand tool assembly 2 is connected to the second auxiliary fixing assembly 3 via the eighth connecting column 29. The hand tool assembly 2 is used to implement punching of the hand blank 5, remove excess material 52, and obtain a hand 51. The contour limiter 22 matches the shape of the hand blank 5, and limits and fixes the hand blank 5 on both sides. Specifically, as Figure 9-10 As shown, the profiling stopper 22 includes an upper profiling member 221 and a lower profiling member 222. The upper profiling member 221 and the lower profiling member 222 are separated from each other, respectively corresponding to the upper and lower parts of the hand blank 5, and matching the shape of the hand blank 5, so as to limit the hand blank 5. Under the action of external force, the hand blank 5 can be pressed against each other, so as to achieve accurate fixation, thereby avoiding shaking during the punching process that affects the punching quality. Figure 11-14 As shown, the hand mold blank 7 includes a hand 51 and an arm 71. The hand 51 is obtained by punching the hand blank 5, and then welded with the arm 71 to obtain the hand mold blank 7. The welding position between the hand 51 and the arm 71 can be Fig.11 The straight line shown, Fig.12 The oblique line shown (angle α is set as required), Fig.13 The one end shown is tilted, Fig.12 The two ends shown can be selected according to the needs of welding, punching process, production efficiency, and production cost to improve the applicability of the product. At this time, the shapes of the upper profiling member 221 and the lower profiling member 222 also need to be matched according to the various shapes of the hand 51 to fix the entire hand blank 5 well. The blade plate 21 and the clamping plate 23 are both provided with a hollow structure that matches the outer contour of the hand 51. The hollow structure provides a space for the tool to move, which is convenient for the tool to punch the hand blank 5. At the same time, the punching surface of the hand blank 5 is exactly the area to be welded, which solves the problems of sand holes, insufficient penetration, or perforation, and difficult weld processing in the conventional punching processing method. By adding material to compensate for the punching surface of the die-casting blank, the method and equipment of punching the surplus material as a whole greatly improve the production efficiency and quality of the hand mold.

[0045] As an optional implementation, Figure 3As shown, the tool includes a first tool 24, a second tool 25, and a third tool 26. The first tool 24 and the second tool 25 are fixed to the first auxiliary fixing component 1, and the third tool 26 is fixed to the second auxiliary fixing component 3. Therefore, when the first auxiliary fixing component 1 moves downward, it drives the first tool 24 and the second tool 25 to move downward synchronously. The first tool 24, the second tool 25, and the third tool 26 can cooperate with each other to punch and separate the hand 51 and the material head 52 from each other. The first tool 24 matches the finger part of the hand blank 5, that is, the first tool 24 is a tool combination composed of five finger-shaped structures, all of which are arc-shaped. The second tool 25 and the third tool 26 match the hand 51 of the hand blank 5, and are all straight-line-shaped. The second tool 25 and the third tool 26 cooperate with each other to facilitate rapid punching and improve punching efficiency.

[0046] As an optional implementation, Figure 1-5 As shown, the fastening assembly 4 includes a pushing part 41 and a connecting part 42. The fastening assembly can be a linear motor, a motor screw combination, a cylinder, a hydraulic cylinder and other devices, which are used to output linear reciprocating motion, realize the tightening of the hand blank 5, and cooperate with the contour limiter 22 to realize the firm fixation of the hand blank 5. The connecting part 42 can be sleeved with the head 52 of the hand blank 5, that is, the shape of the connecting part 42 matches the shape of the palm side of the head 52, and is slightly smaller than the head 52, so that it is embedded in the inside of the head 52 under the action of the pushing part 41 to achieve the tightening of the hand blank 5; the pushing part 41 can push the connecting part 42 to tighten with the head 52. Specifically, the fastening assembly 4 is connected to the head 52 through the inner support 43, and the inner support 43 includes a support body 431, a connecting hole 432, an air avoidance groove 433 and a support position 434. The support body 431, the connecting hole 432, the air avoidance groove 433 and the support position 434 are an integrated structure. The inner support member 43 is connected to the transmission shaft 44 of the pushing part 41 through the connecting hole 432 to realize the transmission of force and motion between the pushing part 41 and the inner support member 43. The other end of the inner support member 43 is sleeved with the material head 52 through the supporting position 434 to realize the fixation with the hand blank 5. The connection position between the inner support member 43 and the hand blank 5 is provided with an air avoidance groove 433 to avoid the punching edge of the hand blank 5. Before punching the hand blank 5, the upper profiling member 221 and the lower profiling member 222 are first closed to press the hand blank 5, and then the inner support member 43 is pushed into the inside of the hand blank 5 under the action of the force of the pushing part 41. Through the joint action of the inside and the outside, the punching surface of the hand blank 5 is shaped, which effectively ensures the punching accuracy and punching effect of the hand blank 5 and improves the product yield and quality.

[0047] As an optional implementation, Figure 2As shown, the hand blank 5 punching and shaping device also includes a limit assembly 6, which includes a fixing portion 61 and a limit rod 62. The fixing portion 61 is connected to the first auxiliary fixing assembly 1. The limit rod 62 can abut against the material head 52 when the first auxiliary fixing assembly 1 moves downward. The height of the limit rod 62 can be set as needed, and can also be a telescopic rod. The limit assembly 6 facilitates better control of the punching height, that is, the downward movement stroke of the first auxiliary fixing assembly 1.

[0048] As an optional implementation, Figure 1-6 As shown, the first auxiliary fixing assembly 1 includes an upper base plate 11, an upper panel 12 and an upper ejector panel 13 which are detachably connected in sequence, and the upper ejector panel 13 is connected to the hand tool assembly 2. Specifically, the upper base plate 11, the upper panel 12 and the upper ejector panel 13 are connected by a first connecting column 14, the upper base plate 11 and the upper panel 12 are connected by a second connecting column 15, and the upper panel 12 and the upper ejector panel 13 are also connected by a third connecting column 16, so that the first auxiliary fixing assembly 1 is a solid whole. At the same time, the upper ejector panel 13 is connected to the blade plate 21 through a fourth connecting column 17, and the upper ejector panel 13 is also connected to the contour limiter 22 through a fifth connecting column 18. This connection structure is compact, which facilitates smooth movement and force transmission between the first auxiliary fixing assembly 1 and the hand tool assembly 2.

[0049] As an optional implementation, Figure 1-6 As shown, the second auxiliary fixing assembly 3 includes a lower pad 31, a lower ejector plate 32 and a lower bottom plate 33 which are detachably connected in sequence; the lower pad 31 is connected to the hand tool assembly 2. Specifically, the lower pad 31, the lower ejector plate 32 and the lower bottom plate 33 are connected to the clamping plate 23 through the ninth connecting column 34, the lower ejector plate 32 and the lower bottom plate 33 are connected to the clamping plate 23 through the tenth connecting column 35, the lower ejector plate 32 and the lower bottom plate 33 are connected through the eleventh connecting column 36, and the lower pad 31 and the lower ejector plate 32 are connected through the twelfth connecting column 37. This connection structure is compact, so that the second auxiliary fixing assembly 3 is used as a whole, and it is convenient to coordinate the force and movement with the hand tool assembly 2.
