Description

Technical Field

[0001] The utility model belongs to the field of molds, and particularly relates to a continuous mold with a simple structure. Background Art

[0002] A continuous die is a cold stamping die that uses several different stations on a die to simultaneously complete multiple stamping processes. The material changes shape by applying force and appropriately shaped die slots. Its main feature is that it can continuously manufacture products. Compared with traditional discrete dies, continuous dies have certain advantages in production efficiency and automation.

[0003] By applying force, the material will change along with the shape of the mold groove until the shape of the product is the same as the shape of the mold groove. Due to the large contact area between the product and the mold, the product of the continuous mold is tighter inside the mold, which is prone to adhesion and makes demolding difficult. Tools are needed to demold the product from the mold. In the process of demolding with tools, the surface of the product and the mold will be damaged, which will affect the quality of the product, cause mold wear, reduce the service life of the mold, and increase the maintenance cost of the mold.

[0004] Therefore, we hope to design a continuous mold with a simple structure to solve this problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a continuous mold with a simple structure, comprising a bottom plate 1, a mold groove 2 is fixedly connected to the upper side of the top 1, a supporting foot 3 is fixedly connected to the lower side of the bottom plate 1, and a positioning rod 4 is fixedly connected to the upper side of the bottom plate 1;

[0026] The outer side of the positioning rod 4 is slidably sleeved with a sliding sleeve 5, the upper side of the sliding sleeve 5 is fixedly connected with a pressing plate 6, the pressing plate 6 is in contact with the mold groove 2, and the lower side of the bottom plate 1 is provided with an ejection component 7;

[0027] The ejection component 7 includes a connecting block 71, which is fixedly connected to the lower side of the base plate 1. A push rod 72 is slidably penetrated inside the connecting block 71. The push rod 72 is movably connected to the base plate 1. The push rod 72 is slidably connected to the mold groove 2. An elastic component 73 is arranged on the outer side of the push rod 72. By setting the ejection mechanism 7, the stamped product in the mold groove 2 is lifted up, which facilitates the separation of the product from the mold.

[0028] The height of the sliding sleeve 5 is greater than the height of the mold groove 2. There are four groups of mold grooves 2 and ejection components 7. The four groups of mold grooves 2 and ejection components 7 are respectively arranged on the upper and lower sides of the base plate 1. By setting the sliding sleeve 5 greater than the height of the mold groove 2, the lifting height of the pressing plate 6 is increased, which facilitates the removal of the stamped product.

[0029] An upper mold is provided on the lower side of the pressing plate 6, and a connecting seat for installation with an external stamping machine device is provided on the upper side of the pressing plate 6. By providing the pressing plate 6 with the connecting seat, it is convenient to connect the pressing plate 6 with the external stamping device.

[0030] The positioning rod 4 is made of alloy steel and is used to position the pressing plate 6. The positioning rod 4 is provided to position the sliding sleeve 5 and the pressing plate 6 to prevent the pressing plate 6 from deflecting.

[0031] The elastic component 73 includes a connecting ring 731, which is fixedly sleeved on the outer side of the push rod 72. The connecting ring 731 is elastically connected to the connecting block 71 via a first spring 732. By setting the elastic component 73, the elastic force of the first spring 732 is utilized to push the product upward.

[0032] The upper surface of the push rod 72 is parallel to the upper surface of the bottom plate 1. A connecting tube 74 is fixedly connected to the lower side of the bottom plate 1. A limiting assembly 75 is arranged inside the connecting tube 74. By setting the upper surface of the push rod 72 to be parallel to the upper surface of the bottom plate 1, the push rod 72 is prevented from passing through the bottom plate 1 and affecting the product stamping.

[0033] The limiting assembly 75 includes an insert rod 751, which is slidably sleeved inside the connecting tube 74, and a second spring 752 is arranged inside the connecting tube 74;

[0034] One end of the second spring 752 is fixedly connected to the insertion rod 751, and the other end of the second spring 752 is fixedly connected to the connecting tube 74. A fixing block 76 is fixedly sleeved on the outer side of the insertion rod 751, and the insertion rod 751 is slidably sleeved inside the push rod 72. By setting a limit assembly 75, the position of the push rod 72 is limited during the stamping process.

[0035] See also Figure 1-Figure 4, as the first embodiment of the utility model: in order to solve the problem that the gap between the edge of the material and the mold groove is relatively narrow, which makes it inconvenient for the product to be separated from the mold, the user first places the part to be stamped inside the mold groove 2, and then stamps the part by moving the pressing plate 6 downward. During the downward displacement of the pressing plate 6, the sliding sleeve 5 keeps sliding on the outside of the positioning rod 4 to prevent the pressing plate 6 from shifting. When the stamping is completed and the product needs to be taken out, the limit assembly 75 is operated to cancel the force applied by the limit assembly 75 to the push rod 72. The push rod 72 drives the connecting block 71 and the push rod 72 to move upward under the action of the elastic force of the first spring 732. During the upward movement, the push rod 72 lifts the part inside the mold groove 2, which facilitates the separation of the product from the mold.

[0036] As the second embodiment of the present utility model: based on the description in the above embodiment, further, when the user needs to operate the limit assembly 75 to take out the accessories, the fixed block 76 is moved to the right, and the fixed block 76 drives the insertion rod 751 fixedly connected thereto to move. While the insertion rod 751 moves, it squeezes the second spring 752. The second spring 752 is compressed and deformed by the force. When the insertion rod 751 moves to disengage from the ejector rod 72, the insertion rod 751 loses its limiting effect on the ejector rod 72. The ejector rod 72 moves upward under the elastic force of the first spring 732 to eject the accessories, thereby facilitating the separation of the product from the mold.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
