Description

Technical Field

[0001] The invention relates to the field of shoe nail production, in particular to a spot casting injection automatic dehydration outlet shoe heel nail top leather mold. Background Art

[0002] Most existing shoe spikes are made by injection molding. The molten TPU material is injected into the mold cavity by an injection machine, cooled and formed, and then the injection port section is cut off, resulting in a cut mark on the finished product. This mark makes the outer surface of the heel pad uneven. Especially for round heel pads, the installer can easily install the cut mark on the outside of the heel, thereby affecting the aesthetics of the entire shoe. Since the sales price of the shoe spike is relatively low, if the injection port mark is processed by polishing technology, the cost of the shoe spike will be greatly increased.

[0003] A Chinese invention patent with publication number "CN201669840U" discloses a shoe heel stud mold, including a mold frame, a mold base arranged on the mold frame and a top mold mechanism under the mold base. The mold base is provided with a groove consistent with the heel pad, and a heel stud hole is provided in the middle of the bottom of the groove. The top mold mechanism is composed of a lift plate, a top piece and a lift plate lifting device. The top piece is fixed on the lift plate and faces the heel stud hole, and the lift plate lifting device is connected to the lift plate.

[0004] However, the above-mentioned shoe spike heel mold still has the following defects: First, the groove is directly opened on the mold base, and the heel of the shoe stud needs to be poured gradually. The pouring of the shoe stud heel is cumbersome and cannot meet the needs of rapid production. In addition, manual pouring needs to be repeated after each demoulding, which greatly increases the complexity of shoe stud production. At the same time, the overall volume of the mold base is large, and the groove is set on the mold core. The hot melt is easy to remain on the surface of the mold base, which pollutes the mold. The existing pouring also adopts the pouring channel method. However, when the shoe stud cools, the hot melt will also cool in the pouring channel, causing the pouring channel to be blocked, affecting the production of the shoe stud; Second, the heel nail is directly placed in the heel nail hole. During the casting process of the heel of the shoe nail, the heel nail will swing, causing the heel nail of the shoe nail to deviate from the heel of the shoe nail, resulting in a high defective rate of the shoe nail production, which increases the production cost; Third, the studs are cooled naturally during the casting process. The hot melt takes a long time to cool in the casting groove. During the cooling process, the heat is transferred to the mold base, which can easily cause the groove on the mold base to deform and cause irregular shape of the stud heel.

[0005] Therefore, it is necessary to make improvements to the above-mentioned defects. Summary of the invention

[0006] The purpose of the present invention is to provide a spot-casting injection automatic dehydration outlet heel nail top leather mold to solve the above problems existing in the prior art.

[0008] By adopting the above technical solution: by installing the mold core on the mold frame, first placing the heel nail on the mold frame during the shoe nail casting, the hot melt flows into multiple casting grooves through the flow holes connected to the casting channel on the mold core, and the hot melt will not flow to the mold surface, thereby improving the overall cleanliness of the mold. When the hot melt is cooled, the mold frame can separate the first mold core from the second mold core through the inner mold frame, and the cooled glue column in the casting channel stays in place. The top mold device demolds the shoe nail in the casting groove and ejects the glue column, thereby achieving efficient production of the shoe nail. Compared with the prior art method of directly opening a groove on the mold base and gradually casting the groove, the present invention can achieve hidden incisions by placing the mold core on the mold base and the casting channel on the mold core, and can also achieve high adaptability of the mold frame by replacing the mold core, thereby improving the diversity of shoe nail production methods.

[0010] By adopting the above technical solution: the inclined guide column and the first inclined guide groove cooperate with each other, when the mold is opened, the mold frame is always maintained in the vertical direction of the mold core, and at the same time the inner mold frame moves left and right relative to the mold frame, the first mold core is separated from the second mold core, and the rear mold ejecting device can eject the shoe spikes and the rubber column in the casting channel, thereby realizing efficient production of shoe spikes. In addition, by dividing the mold core into an upper mold and a lower mold, and the glue inlet of the upper mold can realize the rapid glue injection into the pouring channel, because the cover plate covers the upper mold, the pouring groove of the upper mold is closed, and the hot melt will not overflow when filling the pouring groove, thereby reducing the defective rate of the nail heel during the pouring process, and the pouring channel is located in the space between the bottom end face of the pouring groove and the farther end face of the lower mold, and the flow hole and the heel nail hole are on the same side of the pouring groove. After the pouring is completed, the cut mark is located on the connecting surface between the heel of the nail and the heel nail. When the shoe nail is assembled, the cut mark is hidden at the connection. The overall integrity of the outer side of the shoe nail is high and the shape is more beautiful. At the same time, the shoe nail can be directly taken out from the pouring groove, which can save the operation of manual shearing and simplify the production process. In addition, the top mold device can separate the upper mold from the lower mold through the top mold hole, quickly eject the cooled glue column in the pouring channel, and quickly clean the pouring channel.

[0014] By adopting the above technical solution: the pouring channel is divided into the main pouring channel and the auxiliary pouring channel, which can accurately control the pouring position and flow, reduce material waste, and reduce production costs. At the same time, multiple auxiliary pouring channels can realize the diversion of hot melt, reduce the resistance of hot melt during the flow process, and improve the material flow efficiency. In addition, the glue inlet is located in the upper mold, and the hot melt can flow quickly from the glue inlet to the pouring channel, reducing the intervention of manual pouring and speeding up the production rhythm.

[0016] By adopting the above technical solution: the ejector device improves the demoulding efficiency and accuracy through the ejector rod and the ejector rod, reduces manual operation, and improves the level of production automation. The fixed connection between the ejector rod, the mold core and the ejector plate ensures the accuracy and consistency of demoulding, improving product quality.

At the same time, the mold opening device on the mold base can clamp the clamping block and the fixed block of the lower mold, so that the heel nail in the heel nail hole is limited, effectively preventing the heel nail from shifting during the casting process, and reducing the defective rate of the shoe spikes.

[0021] The above-mentioned spot-casting injection automatic dehydration outlet heel nail top leather mold can be further configured as: the mold opening device includes a first moving block, the first moving block is detachably connected to the inner mold frame, a first placement hole is opened in the middle of the first moving block, and a second placement hole is opened in the sliding groove at a position corresponding to the first placement hole, a slider spring is arranged in the first placement hole and the second placement hole, a second moving block is arranged on the side of the first moving block away from the mold base, the first moving block and the second moving block are slidably connected by a connecting rod, and a moving piece is slidably connected to the end of the second moving block away from the first moving block, and the second moving block drives the movement of the first moving block through the moving piece to realize the opening and closing movement between the clamping block and the lower module.

Since the circulation hole is located on the end surface connected to the pouring groove and the heel nail hole, when the shoe nail is demoulded, the incision mark is on the connecting surface of the heel nail and the heel block. When the shoe nail is assembled, the outer surface of the heel pad is complete, and the overall appearance of the shoe nail is high; Second, the upper mold and the lower mold of the mold core are divided into multiple parts, and the lower mold is divided into a clamping block and a fixing block. An elastic member is arranged between the clamping block and the fixing block, so that the heel nail hole is enlarged and the heel nail can be quickly placed therein. Then the mold opening device re-attaches the clamping block and the fixing block, so that the heel nail is tightly clamped by the heel nail hole. The heel nail will not shift during the casting process, and the overall appearance of the produced shoe spikes is consistent, thereby reducing the defective rate of the shoe spikes. Third, when the inner mold frame of the mold opening device slides in the slide groove of the mold base, the marbles in the marble holes at the bottom of the slide groove are bounced into the positioning holes of the inner mold frame, thereby limiting the maximum sliding distance of the inner mold frame, thereby preventing the problem of unstable placement of the heel pins caused by the excessive separation distance between the clamping block and the fixed block in the lower mold, and at the same time preventing the mold opening device from separating from the mold base, thereby improving the stability of the mold opening device; Fourth, the cooling pipe in the top block cooperates with the heat dissipation groove on the mold base to quickly cool the mold core, improve the cooling efficiency of the hot melt in the casting groove, and cool the mold at the same time to prevent deformation and damage of the mold due to excessive temperature, thereby increasing the service life of the mold; Fifth, the mold frame, mold base and mold core cooperate with each other. By setting the mold core on the mold base, the production needs of various shoe spikes can be met by replacing the mold core. The mold frame and the mold base have high adaptability, and the overall volume of the mold frame and the mold base is small, and can be placed in various small spaces.

After the hot melt is cooled, the mold frame 1 can separate the first mold core 23 from the second mold core 24 through the inner mold frame 27, and the cooled glue column in the casting channel 25 stays in place. The top mold device 3 demolds the shoe nail in the casting groove 21 and ejects the cooled glue column, thereby realizing efficient production of the shoe nail. Compared with the prior art method of directly opening a groove on the mold base 4 and gradually casting the groove, the present invention can achieve hidden incisions by placing the mold core 2 on the mold base 4 and the casting channel 25 on the mold core 2, and can also achieve high adaptability of the mold frame 1 by replacing the mold core 2, thereby improving the diversity of shoe nail production methods.

The mold core 2 is divided into an upper mold 231 and a lower mold 232, and the glue inlet 234 of the upper mold 231 can realize rapid glue injection into the pouring channel 25. Since the cover plate 28 covers the upper mold 231, the pouring groove 21 of the upper mold 231 is closed, and the hot melt will not overflow when filling the pouring groove, thereby reducing the defective rate of the heel of the nail during the pouring process. The pouring channel 25 is located in the space between the bottom end face of the pouring groove and the farther end face of the lower mold 232, and the flow hole 26 and the heel nail hole 22 are on the same side of the pouring groove.

After the pouring in the pouring groove 21 is completed, the shoe nail is ejected through the top mold device 3. The pouring channel 25 is divided into a main pouring channel 251 and an auxiliary pouring channel 252, which can accurately control the pouring position and flow rate, reduce material waste, and reduce production costs. At the same time, multiple auxiliary pouring channels 25 can realize the diversion of hot melt, reduce the resistance of hot melt during the flow process, and improve the material flow efficiency. In addition, the glue inlet 234 is located in the upper mold 231, and the hot melt can quickly flow from the glue inlet 234 to the pouring channel 25, reducing the intervention of manual pouring and speeding up the production rhythm.

[0035] like Figure 7 , Figure 8The top mold device 3 shown includes a top mold plate 31 and a sliding plate 32. The top mold plate 31 is provided with a top mold column 311. The end of the top mold column 311 away from the top mold plate 31 is sleeved with a return spring 312. The sliding plate 32 is fixed with a top mold rod 322 and an ejector rod 321. One end of the top mold rod 322 is in contact with the mold core 2, and the other end is fixedly connected to the mold frame 1 that passes through the top mold plate 31. The outer periphery of the ejector rod 321 is sleeved with an ejector tube. One end of the top mold tube 323 is in contact with the sliding plate 32, and the other end is connected to the casting channel 25. The end of the ejector rod 321 away from the sliding plate 32 is placed below the mold core 2, and the other end is fixedly connected to the sliding plate 32. The ejector tube and the top mold rod 322 are used to realize the rapid demoulding of the shoe spikes. The top mold device 3 improves the demoulding efficiency and accuracy through the ejector rod 321 and the top mold rod 322, reduces manual operations, and improves the level of production automation. The fixed connection between the ejector rod 321, the mold core 2 and the ejector mold plate 31 ensures the accuracy and consistency of demoulding, and improves the product quality. The setting of the reset spring 312 quickly resets the sliding plate 32, and the ejector rod 321 can quickly and repeatedly demould the spikes, thereby improving work efficiency. In addition, the ejector mold device 3 has strong adaptability and can flexibly respond to different production requirements, ensuring the efficiency and safety of production.

[0036] like Figure 1 , Figure 2 , Fig.11 The mold frame 1 shown is provided with a mold base 4, and the inner mold frame 27 is arranged above the mold base 4. A second inclined guide groove 41 is opened on the mold base 4, and slide grooves 42 are opened on both sides of the mold base 4. The inner mold frame 27 is slidably connected to the mold base 4 through the slide grooves 42. A plurality of marble holes 421 are arranged at the bottom of the slide groove 42, and marbles 422 are arranged in the positioning holes 272. Positioning holes 272 are arranged at intervals at the connecting part between the inner mold frame 27 and the slide groove 42. The positioning holes 272 are used to control the maximum stroke of the mold opening device 5. A core groove 273 for accommodating the mold core 2 is opened in the middle of the inner mold frame 27. A plurality of wedge blocks 274 are arranged on both sides of the inner mold frame 27. The wedge blocks 274 are used to make the clamping block 241 and the fixing block 242 tightly clamped. The inner mold frame 27 can move left and right through the slide groove 42 on the mold base 4. During the upward movement of the mold frame 1, the inclined guide column 11 can quickly separate the first mold core 23 and the second mold core 24 on the inner mold frame 27 through the first inclined guide groove 271 of the inner mold frame 27 and the second inclined guide groove 41 on the mold base 4, so that the shoe spikes in the casting groove 21 will produce an incision at the flow hole 26. In addition, the inner mold frame 27 will be stuck with the marble 422 through the positioning hole 272 at the bottom during the sliding process of the mold base 4, so as to control the sliding distance and effectively prevent production problems caused by the excessive sliding distance of the inner mold frame 27. The wedge block 274 can limit the inner mold frame 27 when the clamping part and the fixing part of the inner mold frame 27 and the lower mold 232 need to be tightly fitted, so as to prevent the inner mold frame 27 and the lower mold 232 from automatically popping open, thereby improving the stability during the casting process.

[0037] The mold frame 1 includes a bottom plate 12, fixed plates 13 are provided on both sides of the bottom plate 12 in the vertical direction, the top mold device 3 is arranged between the fixed plates 13, the mold base 4 is fixed to the side of the fixed plate 13 away from the bottom plate 12, and a plurality of heat dissipation grooves 43 are provided on the mold base 4.

A plurality of sliding holes 46 for the ejector rod 321 to pass through are provided between the movable hole 45 and the sliding groove 44. The top mold device 3 realizes a contact connection with the mold core 2 by inserting the ejector rod 321 and the top mold rod 322 into the movable hole 45 and the sliding hole 46. A mold opening device 5 is provided in the sliding groove 44. The mold opening device 5 is used to realize the automatic opening and closing of the clamping block 241 and the fixed block 242. The mold frame 1 supports the mold through the bottom plate 12 and the fixed plate 13, and reduces the overall volume of the mold frame 1. The mold frame 1 can be placed in a smaller space, and by providing a heat dissipation groove 43, a sliding hole 46 and a movable hole 45 on the mold base 4, the hot melt can be quickly cooled down during the stud casting process and the top mold device 3 can quickly eject the stud. At the same time, the mold opening device 5 on the mold base 4 can clamp the clamping block 241 and the fixing block 242 of the lower mold 232, so that the heel nail in the heel nail hole 22 is limited, effectively preventing the heel nail from shifting during the casting process, and reducing the defective rate of the shoe nail.

[0038] like Fig. 9 The mold opening device 5 shown includes a first movable block 51, which is detachably connected to the inner mold frame 27. A first placement hole 511 is opened in the middle of the first movable block 51, and a second placement hole 441 is opened in the sliding groove 44 at a position corresponding to the first placement hole 511. Slider springs 512 are arranged in the first placement hole 511 and the second placement hole 441. A second movable block 52 is arranged on the side of the first movable block 51 away from the mold base 4. The first movable block 51 and the second movable block 52 are slidably connected through a connecting rod 53. A movable sheet 54 is slidably connected to the end of the second movable block 52 away from the first movable block 51. The second movable block 52 drives the movement of the first movable block 51 through the movable sheet 54 to realize the opening and closing movement between the clamping block and the lower mold 232. When the shoe spike mold is opened, the slider spring 512 in the first connecting block cooperates with the inclined guide column 11 to move the first mold core 23 and the second mold core 24 on the inner mold frame 27 to the specified position, and the ejecting mold device 3 ejects the shoe spike, and then the mold opening device 5 moves toward the middle of the mold base 4 in the sliding groove 44 through the first connecting block, driving the inner mold frame 27 to fit again, and then the first mold core 23 and the second mold core 24 are re-synthesized into a complete casting whole, thereby achieving efficient repeated production.

[0039] like Fig.10The mold frame 1 shown is provided with a top block 14 above the inner mold frame 27, a top plate 15 is fixed to one end of the top block 14 away from the mold core 2, a glue inlet pipe 235 is provided in the middle of the top plate 15 and connected to the glue inlet 234, a fixing groove 141 is provided in the middle of the top block 14, the top block 14 is fixed on the mold base 4 and the mold core 2 is buckled through the fixing groove 141, the inclined guide column 11 is fixedly connected to the top plate 15, the top block 14 is provided with a third inclined guide groove 142, and the inclined guide column 11 is slidably connected with the inner mold frame 27 and the mold base 4 through the third inclined guide groove 142. The inclined guide column 11 cooperates with the third inclined guide groove 142, the top block 14 and the top plate 15 can always be kept in the vertical direction of the mold frame 1 when the mold is opened, reducing the deviation of the top block 14 and the top plate 15 when being lifted, and ensuring the stability of the overall structure of the mold frame 1. In addition, the fixing groove 141 in the middle of the top block 14 can completely accommodate the mold core 2, which can protect the mold core 2 and stabilize the top cover in the fixing groove 141, making it convenient to quickly demould the studs in the casting groove 21, thereby improving production efficiency.

[0040] A plurality of cooling pipes 143 are provided on one side of the top block 14 close to the top plate 15. The cooling pipes 143 are close to the fixed groove 141. Cooling interfaces 144 are fixed at both ends of the cooling pipes 143. The cooling pipes 143 cool the mold core 2 through the cooling interfaces 144. Stop blocks 145 are provided on both sides of the fixed groove 141. The stop blocks 145 can abut against the upper mold 231. The cover plate 28 is detachably connected between the stop blocks 145. The stop blocks 145 are provided with movable grooves 146. The cover plate 28 can be taken out from between the stop blocks 145 through the movable grooves 146. The cover plate 28 is placed in the fixed groove 141. The top block 14 can drive the cover plate 28 to move up and down during the movement, thereby realizing the automatic edge sealing of the casting groove 21. At the same time, the stop blocks 145 can limit the cover plate 28 to prevent the cover plate 28 from deviating in the top block 14 and causing inaccurate sealing of the casting groove 21. In addition, the top block 14 has multiple cooling pipes 143 and cooling water is introduced through the cooling interface 144, which can cool the core 2 during the casting process to prevent the core 2 from overheating and deformation, thereby reducing the defective rate of stud casting.

[0041] The specific implementation of the present invention is as follows: the mold frame 1 is placed at the shoe spike production site, and the mold opening device 5 and the top mold device 3 are connected to the driving system, and the glue feeding pipe 234 is connected to the glue feeding device. Then the mold opening device 5 cooperates with the slider spring 512 in the first moving block 511 and the inclined guide column 11 to move the top block 14 and the top plate 15 upward, and the inner mold frame 27 drives the first mold core 23 and the second mold core 24 to move left and right. At the same time, the clamping block 241 and the fixing block 242 of the lower mold 232 are placed through the elastic member 244 in the placement groove 243. The heel nail hole 22 is enlarged by a certain gap. After the heel nail is placed in the heel nail hole 22 through the casting groove 21, the mold opening device 5 moves in the sliding groove 44 toward the middle of the mold base 4, driving the inclined guide column 11 to move down and fit the inner mold frame 27, so that the first mold core 24 and the second mold core 25 are re-fitted into the mold core 2 as a whole. The wedge block 274 is buckled to limit the inner mold frame 27, and then the rubber inlet hose 235 starts to inject hot melt into the casting channel 25. The hot melt first moves from the main casting channel 251 to the auxiliary casting channel 252, and then The hot melt flows into the casting groove 21 through the flow hole 26 at the end of the auxiliary casting channel 252 until the casting groove 21 is filled with hot melt. At this time, the cooling pipe 143 on the top block 14 continuously passes cooling water through the cooling interface 144 to efficiently cool the mold core 2. After the follower block is cooled and formed, the wedge block 274 is opened, and the mold opening device 5 pulls the inner mold frame 27 to move left and right and moves the top block 14 to the top of the mold through the first inclined guide groove 271 and the inclined guide column 11. Since the cover plate 28 is detachably connected to the fixed groove 141, the cover plate 28 is synchronously moved to The casting groove 21 is exposed again when the inner mold frame 27 moves to a certain position relative to the slide groove 42 of the mold base 4, the positioning hole 272 is engaged with the marble 422 in the marble hole 421 to prevent the inner mold frame 27 from excessive movement, and then the top mold device 3 demoulds the shoe spikes in the casting groove 21 and the glue column in the casting channel 25 through the movable hole 45 and the sliding hole 46 on the mold base 4 through the ejector rod 321 and the top mold tube 323, and then under the action of the reset spring 312, the top mold device 3 is reset to carry out the next round of shoe spike production.
