Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for producing and processing protective shoes. Background Art

[0002] In the production process of shoe soles, most processes use injection molding. Molds are indispensable tools when using this process. In the traditional production model, after the soles are compacted and shaped, the shoe molds inside the soles need to be removed manually, which is time-consuming and labor-intensive. In addition, the human factors are unstable and the force is too great, resulting in deformation of the soles and increasing the scrap rate of the products.

[0003] In response to the above problems, the Chinese patent with publication number CN218488990U discloses a metal shoe mold that is convenient for removing finished products, including a lower mold and an upper mold, a pressing film is fixedly installed on the upper mold, the lower mold and the upper mold are rotatably connected by a hinge, a mold groove is provided at the top of the lower mold, the pressing film cooperates with the mold groove, and a shoe mold plate is slidingly set inside the mold groove, a support spring is provided between the bottom wall of the shoe mold plate and the bottom inner wall of the mold groove, and limiting components for limiting the movement of the shoe mold plate are also inserted on the side walls of the lower mold.

[0004] In the above solution, the restriction on the shoe template is released by operating the restriction component, so that the shoe template and the shoe mold are pushed out under the action of the elastic force of the supporting spring, thereby completing the automatic demoulding of the shoe mold.

[0005] Therefore, a new solution is proposed to solve this problem. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an injection mold for the production and processing of protective shoes, which can quickly unload the shoe body after injection molding by arranging an output part and an ejection device in conjunction with the injection mold.

[0007] The above technical objectives of the present utility model are achieved through the following technical solutions: An injection mold for the production and processing of protective shoes, comprising a pressing mold and a mold base hinged to the pressing mold, a shoe mold boss being provided on the mold base, a molding cavity being provided on the pressing mold corresponding to the shoe mold boss, an ejection device being provided in the mold base, a first adjustment groove and a second adjustment groove being connected to the first adjustment groove being provided in the mold base, an ejection block being slidingly provided in the first adjustment groove, notches being provided at both ends of the first adjustment groove, limit plates sliding in the notches being fixedly connected at both ends of the ejection block, a spring being provided in the notch, one end of the spring being fixedly connected to the notch, and the other end of the spring being fixedly connected to the limit plate, an output member being provided in the second adjustment groove to drive the ejection block to lift up.

[0008] By adopting the above technical solution, the output cylinder outputs, driving the connecting plate and the adjusting wheel rotatably connected to the connecting plate to move toward the end away from the output cylinder. Since the bottom of the ejection block is provided with an inclined groove, the adjusting wheel drives the ejection block to move upward during the movement toward the ejection block. The limit plates provided at both ends of the ejection block have notches symmetrically opened on both sides of the first adjusting groove, and a spring is provided between the limit plate and the notch. When the limit plate moves upward with the ejection block, the top of the limit plate contacts the top inner wall of the notch. At this time, the spring is in a stretched state, and the ejection block punches the produced injection-molded shoe body out of the shoe mold boss. When the output cylinder is reset, and the adjusting wheel is driven to reset, the ejection block is reset under the elastic force of the spring to wait for the next work.

[0009] The present invention is further configured as follows: the first adjustment slot and the second adjustment slot are vertically arranged.

[0010] The utility model is further configured as follows: a limiting column is fixedly connected in the first adjusting groove, a straight groove is opened on the ejection block, and the limiting column is slidably connected to the straight groove.

[0011] By adopting the above technical solution, when the ejection block moves up and down in the first adjustment groove, the moving position of the ejection block is further restricted by the limiting column and the straight groove provided on the ejection block.

[0012] The utility model is further configured as follows: the output member includes an output cylinder fixedly connected to the second adjusting groove, the telescopic end of the output cylinder is fixedly connected to a connecting plate, the connecting plate is rotatably connected to an adjusting wheel at one end away from the output cylinder, and an oblique groove is provided at the bottom of the ejection block, and the adjusting wheel is in conflict with the oblique groove.

[0013] By adopting the above technical solution, the output of the output cylinder drives the connecting plate and the adjusting wheel rotatably connected to the connecting plate to move toward the end away from the output cylinder. Since the bottom of the ejection block is provided with an inclined groove, the adjusting wheel drives the ejection block to move upward during the movement toward the ejection block, thereby realizing the sliding of the ejection block in the first adjusting groove.

[0014] The utility model is further configured as follows: a positioning block is provided on the mold base, and a positioning groove is provided on the pressing mold.

[0015] By adopting the above technical solution, the positioning block provided on the mold base and the positioning groove opened on the pressing mold are used.

[0016] The utility model is further configured as follows: heat dissipation holes are provided on the mold base and the pressing mold.

[0017] By adopting the above technical solution, the heat dissipation holes play a role in heat dissipation.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The output part and the ejection device are arranged to cooperate with the injection mold to quickly unload the shoe body after injection molding. BRIEF DESCRIPTION OF THE DRAWINGS
