Description

Technical Field

[0001] This utility model mainly relates to the field of cork processing molds, specifically a cork stopper pressing mold. Background Technology

[0002] Cork is a natural material that is very lightweight and quite flexible due to its unique internal structure. Cork also possesses sound insulation, water resistance, fire resistance, and slip resistance properties, making it widely used in cushioning and decorative materials.

[0003] Cork stoppers are lightweight and offer excellent sealing properties, making them suitable for sealing various glass bottles. Cork stoppers are produced by high-pressure compaction of cork granules. Currently, molds for making cork granules typically consist of an upper and lower mold. Material is filled into the lower mold, and then the upper mold presses the material to complete the cork stopper production. This type of mold has the drawback of being single-function, only capable of producing cork stoppers of a single density and size. Different sizes of cork stoppers require different mold sizes, leading to increased production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cork pressing mold that can be freely combined with upper, middle, and lower molds to adapt to the production of corks of different densities and specifications, greatly saving mold costs.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A cork pressing mold includes a base with support plates on both sides and an opening in the middle. Limiting plates are detachably mounted on the top of the two support plates. An ejection mechanism is mounted on the top surface of the base. The ejection mechanism includes an ejection plate positioned between the two support plates and ejection columns arranged in an array on the ejection plate. Limiting holes, corresponding one-to-one with the ejection columns, are arranged in an array on the limiting plate. When the ejection plate is at its lowest position, the ejection columns are not lower than the top surface height of the limiting holes. A lower mold, a middle mold, and an upper mold are stacked sequentially above the limiting plate. The lower mold has lower mold cavities corresponding one-to-one with the limiting holes. The middle mold has middle mold cavities corresponding one-to-one with the lower mold cavities and having the same diameter. A compaction column, corresponding one-to-one with the middle mold cavity, is mounted on the bottom surface of the upper mold.

[0007] The lower mold cavity is a cone with a larger top diameter and a smaller bottom diameter. The diameter of the limiting hole is the same as the bottom diameter of the lower mold cavity, and the diameter of the middle mold cavity is the same as the top diameter of the lower mold cavity.

[0008] A spring is fitted onto the ejector column, and the top of the spring abuts against the bottom surface of the limiting plate.

[0009] The lower die has a countersunk hole, the limiting plate has a threaded hole, and the lower die and the limiting plate are fixed by the countersunk bolt.

[0010] The lower die has a countersunk hole, the limiting plate has a threaded hole, and the lower die and the limiting plate are fixed by the countersunk bolt.

[0011] The middle die has an upper recess on the top surface.

[0012] The middle die has a fastening bolt on each side surface, the ejection plate has a connecting chain on each side, the distal end of the connecting chain is connected with a fastening head, and the fastening head is eccentrically provided with a fastening threaded hole matched with the fastening bolt.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The forming die of the soft cork is divided into an upper die, a middle die and a lower die, the three dies can be freely matched according to the density and the specification of the processed soft cork, thereby improving the utilization rate of the die, avoiding the problem that a set of die can only produce a single specification of soft cork, greatly reducing the die cost and improving the utilization rate of the die.

[0022] As Figures 1-5 The utility model discloses a cork pressing mould, including base 1, the both sides of base 1 set up support plate 11, support plate 11 parallel setting on the both sides top surface of base 1, support plate 11 can be fixed by the mode of welding or bolt fixedly.In the production of cork, support plate 11 is fixed on the workbench of press through bolt or pressing plate. The lower portion of base 1 is provided with an opening 12, and a ejector cylinder or a hydraulic cylinder is installed below the workbench of the press, and the piston rod of the ejector cylinder or the hydraulic cylinder corresponds to the opening 12. A ejecting mechanism 3 is arranged on the top surface of the base 1, and the piston rod of the ejector cylinder or the hydraulic cylinder passes through the opening 12 to drive the ejecting mechanism 3, so that the ejecting mechanism 3 is lifted to eject the cork formed in the mold, which is convenient for the operator to pick up.

[0023] Two support plates 11 top detachable installation limiting plate 2, specifically, limiting plate 2 is fastened on support plate 11 through bolt. The ejecting mechanism 3 includes an ejecting plate 31 arranged between the two support plates 11 and a plurality of ejecting columns 32 arranged on the ejecting plate 31, and the ejecting columns 32 correspond one-to-one to the forming cavities of the mold to eject the corks in the forming cavities of the mold by the lifting action of the ejecting columns 32. A plurality of limiting holes 21 corresponding to the ejecting columns 32 are arranged on the limiting plate 2, and when the ejecting plate 31 is located at the lowermost position, the ejecting columns 32 are not lower than the top surface height of the limiting holes 21. In the embodiment, the top surface of the ejecting columns 32 is flush with the top surface of the limiting plate 2, so as to facilitate the sealing of the bottom surface of the lower mold 4 and the compaction forming of the corks. The limiting holes 21 are used for limiting the ejecting columns 32, so as to facilitate the stable lifting of the ejecting mechanism 3.

[0024] Specifically, a spring 33 is sleeved on the ejecting column 32, and the top of the spring 33 abuts against the bottom surface of the limiting plate 2. When the ejecting mechanism 3 is lifted, the spring 33 is compressed, and when the corks are ejected, the spring 33 is stretched, so as to ensure the stable reset of the ejecting mechanism 3.

[0025] The lower die 4, the middle die 5 and the upper die 6 are sequentially stacked above the limiting plate 2. The lower die 4 is provided with a lower die cavity 41 corresponding to the limiting hole 21. The middle die 5 is provided with a middle die cavity 51 corresponding to the lower die cavity 41 and having the same diameter. The lower die cavity 41 is coaxial with the lower limiting hole 21. The middle die cavity 51 is coaxial with the lower die cavity 41. The middle die cavity 51 serves as a filler hole for the cork particles. The lower die cavity 41 serves as a forming cavity for the cork plug. Specifically, the lower die cavity 41 in the embodiment is conical with a larger top diameter and a smaller bottom diameter. The diameter of the limiting hole 21 is consistent with the bottom diameter of the lower die cavity 41. The diameter of the middle die cavity 51 is consistent with the top diameter of the lower die cavity 41. The top surface of the ejection cylinder 32 closes the bottom of the lower die cavity 41, facilitating the forming of the cork plug. The bottom of the middle die cavity 51 is connected to the top of the lower die cavity 41, facilitating the introduction of the cork particles. The lower die 4 is detachably fixed to the limiting plate 2. In the embodiment, the lower die 4 is provided with a countersunk hole. The limiting plate 2 is provided with a screw hole. The lower die 4 is fixed to the limiting plate 2 by a countersunk bolt, thereby achieving the installation of the lower die 4. The thickness of the middle die 5 is usually 5-10 times that of the lower die. Therefore, the middle die and the lower die are only stacked in the embodiment. The stable stacking is achieved by the weight of the middle die itself. Specifically, the lower die 4 is provided with a lower protrusion 42 at the top of each corner. The middle die 5 is provided with a lower depression 52 at the bottom of each corner. The lower protrusion 42 and the lower depression 52 are triangular. The stacking of the middle die 5 is positioned by the embedded cooperation.

[0026] In the embodiment, the lower die cavity 41 is arranged in two rows, each of which has five lower die cavities 41. The synchronous forming of ten cork plugs can be completed at one time.

[0027] Further, the top surface of the middle die 5 is also provided with a triangular upper depression 53. The top and bottom surfaces of the middle die 5 are symmetrical. The middle die 5 can be placed with any bottom surface facing the lower die 4, which is more convenient for operation.

[0028] The upper die 6 is provided with a compaction column 61 corresponding to the middle die cavity 51 on the bottom surface. The outer diameter of the compaction column 61 is consistent with the inner diameter of the middle die cavity 51. The top of the upper die 6 is fixed to the bottom of the piston rod of the press. The compaction column 61 is pressed into the middle die cavity 51 by the extension of the press, thereby compacting the cork particles into cork plugs.

[0029] More specifically, the middle die 5 is provided with a fastening bolt 54 on each side surface. The ejection plate 31 is provided with a connecting chain 34 on each side. The distal end of the connecting chain 34 is connected to a fastening head 35. The fastening head 35 is eccentrically provided with a fastening screw hole matched with the fastening bolt 54. When the middle die 5 and the lower die 4 are installed, the fastening head 35 can be locked with the fastening bolt 54 through the fastening screw hole. The tightening of the connecting chain 34 can be achieved by the fastening of the screw thread, thereby relatively connecting the middle die 5 and the ejection plate 31. When the ejection mechanism 3 is reset, the middle die 5 can be pulled, so that the middle die 5 will not be dislocated.

[0030] When the cork is made, the operator fills the cork granules into the middle mold cavity 51 so that the cork granules are flush with the top surface of the middle mold cavity 51. Then the upper mold 6 is pressed down by the press, and the cork granules are compacted into the lower mold cavity 41 by pressure, thus completing the compacting and molding of the cork. After the cork is molded, the upper mold 6 is reset, and the ejection plate 31 is raised by the driving of the ejection cylinder, thus ejecting the molded cork, which is then taken out by the operator.
