Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring moulds, in particular to a water valve sealing ring automatic flash removal mould. Background Art

[0002] Water valve seals are indispensable auto parts for new energy vehicles. Water valve seals are mainly used in the coolant circulation system of vehicle battery packs, motor controllers, drive motors and other key components. With the continued rapid development of new energy vehicles in China, the order volume of water valve seals has also reached a record high.

[0003] In the actual production of water valve sealing rings, the water valve sealing ring product contains a skeleton made of PTFE (polytetrafluoroethylene), which needs to be placed in the lower mold cavity during production. The skeleton material is relatively soft. After the upper and lower molds are closed, the skeleton is also bent and tightly attached to the contact surface between the upper and lower molds. After the press is vulcanized and demolded, the product still needs to be manually removed one by one from the excess skeleton material and rubber flash. The subsequent trimming has become an important factor restricting the mass production of water valve sealing rings. At the same time, the quality of manually trimmed products varies from person to person, and the quality risk cannot be well controlled, which causes high labor costs and is not conducive to the production efficiency of the enterprise. Utility Model Content

By closing the upper mold and the lower mold, the cutter head penetrates the water valve sealing ring product and passes through the punching hole and extends into the punching cavity, thereby realizing automatic flash removal of the water valve sealing ring.

[0006] As a further optimized solution of the utility model, the upper mold includes an upper pad and an upper pressure plate. The upper pad is fixedly installed on the top of the upper pressure plate. The punching cavity is opened on the upper surface of the upper pressure plate. The bottom of the upper pad has an opening and is arranged opposite to the punching cavity.

[0007] As a further optimized solution of the utility model, there are multiple cutter heads which are spaced apart and distributed on the upper surface of the lower die, and the multiple cutter heads correspond one by one to the multiple burrs to be sheared of the water valve sealing ring product.

[0009] As a further optimized solution of the utility model, the outer edge of the top end of the cutter head is a punching blade, and the punching blade is a closed-loop structure and corresponds to the edge of the flash of the water valve sealing ring product.

[0010] As a further optimized solution of the utility model, multiple guide pillars are installed on the upper mold and are symmetrically distributed on the bottom edge of the upper mold, and guide holes compatible with the guide pillars are opened on the lower mold. The number of guide holes is multiple and corresponds one-to-one to the multiple guide pillars.

[0011] As a further optimization scheme of the utility model, a symmetrically distributed buffer mechanism is installed between the upper mold and the lower mold. The buffer mechanism includes buffer columns and buffer springs. The buffer columns are symmetrically installed on both sides of the bottom of the upper mold. The buffer springs are sleeved on the buffer columns. The lower mold is provided with sockets that are compatible with the buffer columns.

[0013] The automatic flash removal mold for the water valve sealing ring proposed by the utility model has the following beneficial effects:

[0014] The utility model inserts a water valve sealing ring product with a positioning pin on a cutter head, so that the water valve sealing ring product body and the position where the flash needs to be removed can be stabilized, and then the flattened water valve sealing ring product body is pressed by moving the upper mold downward. As the upper mold continues to fall rapidly, the top of the cutter head passes through the punching hole and extends into the punching cavity, so that the redundant skeleton and flash fixed on the cutter head can be removed, and multiple holes of the water valve sealing ring product can be cut at one time, which is beneficial to improving the cutting quality and cutting efficiency for mass production, and can also well reduce labor costs, which is beneficial to the production efficiency of the enterprise.

By closing the upper mold 1 and the lower mold 2, the cutter head 4 penetrates the water valve sealing ring product and passes through the punching hole 6 and extends into the punching cavity 5, so as to realize the automatic removal of the flash of the water valve sealing ring;

[0027] Specifically, the upper die 1 includes an upper pad 11 and an upper pressing plate 12. The upper pad 11 is fixedly mounted on the top of the upper pressing plate 12. The punching cavity 5 is opened on the upper surface of the upper pressing plate 12. The bottom of the upper pad 11 has an opening and is arranged opposite to the punching cavity 5. When the top of the cutter head 4 extends into the punching cavity 5, the excess skeleton and flash will be brought into the punching cavity 5, which is convenient for shearing and ejecting of waste materials and subsequent discharge operations.

[0028] Specifically, there are multiple cutter heads 4 which are spaced apart on the upper surface of the lower mold 2, and the multiple cutter heads 4 correspond one by one to the multiple flash edges to be sheared of the water valve sealing ring product;

[0029] Furthermore, a positioning pin is provided at the center of the flash edge to be sheared of the water valve sealing ring product, and a positioning hole adapted to the positioning pin is provided in the middle of the top end of the cutter head 4. The water valve sealing ring product is plugged into the top end of the cutter head 4 through the positioning pin to play a positioning role, thereby stabilizing the water valve sealing ring before shearing;

[0030] It should be noted that this water valve sealing ring product is different from the existing water valve sealing ring. The positioning pin and the water valve sealing ring are integrally formed, and the molding mold needs to be improved. A plurality of positioning holes are designed in the mold cavity of the molding mold. When the raw material is placed in the molding mold and pressed by the press, part of the material will enter the positioning hole to form a positioning pin, which is convenient for subsequent positioning and shearing.

[0031] Furthermore, the outer edge of the top of the blade head 4 is a punching blade, which is a closed-loop structure and corresponds to the edge of the flash of the water valve sealing ring product;

[0032] Furthermore, the number of the cutter heads 4 is five and corresponds to the five flash shearing holes of the water valve sealing ring, so that five shearings can be completed in one forming, greatly improving the shearing efficiency and shearing quality;

[0033] Specifically, a plurality of guide pillars 3 are installed on the upper mold 1 and are symmetrically distributed on the bottom edge of the upper mold 1, and a guide hole 8 adapted to the guide pillar 3 is opened on the lower mold 2, and the number of the guide holes 8 is multiple and corresponds to the multiple guide pillars 3 one by one;

[0034] Furthermore, the number of guide pillars 3 is four and they are symmetrically distributed at the four corners of the upper pressing plate 12, and the four guide holes 8 are opened at the four corners of the lower mold 2, and the depth of the guide holes 8 is greater than the length of the guide pillars 3, so that the guide pillars 3 can be fully inserted into the guide holes 8, thereby facilitating the clamping of the upper pressing plate 12 and the lower mold 2;

[0035] Furthermore, a rubber guide sleeve is installed in the guide hole 8. When the bottom end of the guide post 3 is inserted into the guide hole 8, it will be plugged into the rubber guide sleeve, which can avoid damage caused by rigid contact.

[0036] Specifically, a symmetrically distributed buffer mechanism 7 is installed between the upper die 1 and the lower die 2. The buffer mechanism 7 includes a buffer column 71 and a buffer spring 72. The buffer column 71 is symmetrically installed on both sides of the bottom of the upper die 1. The buffer spring 72 is sleeved on the buffer column 71. The lower die 2 is provided with a socket 9 adapted to the buffer column 71. The upper die 1 drives the buffer column 71 to be plugged into the socket 9, so that the buffer spring 72 is squeezed and deformed to perform buffering.

[0037] Furthermore, there are four buffer columns 71 and they are symmetrically distributed at the bottom of the two short sides of the upper pressure plate 12. The four buffer columns 71 are distributed in a rectangular array. Each buffer column 71 is equipped with a buffer spring 72. A cushion block is also installed at the bottom end of the buffer column 71. The cushion block is cylindrical and has an outer diameter greater than the outer diameter of the buffer column 71. The two ends of the buffer spring 72 are respectively connected to the lower surface of the upper pressure plate 12 and the upper surface of the cushion block. The cushion block is adapted to the socket 9, and the height of the cushion block is less than the depth of the socket 9. When the plate 12 moves downward, it will drive the buffer column 71, the buffer spring 72 and the cushion block to move downward, and the cushion block is inserted into the insertion hole 9. The outer diameter of the buffer spring 72 is larger than the inner diameter of the insertion hole 9, so that the buffer spring 72 is still between the upper pressing plate 12 and the lower mold 2. As the upper pressing plate 12 drives the buffer column 71 to move downward continuously, the buffer spring 72 is continuously compressed. The elastic deformation of the buffer spring 72 can absorb the impact force during mold closing, thereby achieving a buffering effect and avoiding damage caused by collision.

[0038] Furthermore, a threaded hole adapted and corresponding to the buffer column 71 is provided on the upper pressing plate 12, and the top of the buffer column 71 has an external thread, so that the top of the buffer column 71 can be quickly installed on the upper pressing plate 12 through the threaded hole, which is convenient for actual assembly operations;

[0039] Specifically, a lower plate insert 10 is inlaid and installed in the middle of the lower mold 2 , the cutter head 4 is fixedly installed on the upper surface of the lower plate insert 10 , and the top end of the cutter head 4 extends to the top of the lower mold 2 .

[0040] In summary, the automatic flash removal mold for the water valve sealing ring proposed by the utility model, by inserting the water valve sealing ring product with a locating pin on the cutter head 4, the water valve sealing ring product body and the position where the flash needs to be removed are stabilized, and then the upper mold 1 is moved downward to press the flattened water valve sealing ring product body. As the upper mold 1 continues to fall rapidly, the top of the cutter head 4 passes through the punching hole 6 and extends into the punching cavity 5, so that the excess skeleton and flash fixed on the cutter head 4 can be removed, and multiple holes of the water valve sealing ring product are cut at one time, which is beneficial to improving the cutting quality and cutting efficiency for mass production, and can also greatly reduce labor costs, which is beneficial to the production efficiency of the enterprise.
