Description

Technical Field

[0001] The utility model belongs to the technical field of large-scale end cap processing and application, and in particular relates to a special mould for producing large-scale end caps. Background Art

[0002] The end cap is a component used to seal the end of a container to isolate the media inside and outside, also known as an end cap. The end cap of a cylindrical container is generally a rotating shell. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined shapes.

[0003] During the pressing and manufacturing process of the head, stable and precise forming and pressing are required. At the same time, fast unloading operations are also required for the pressed head, especially for large heads. Due to their heavy weight, unloading is difficult.

[0004] After searching: (1) Application number / patent number 202320127085.4, a mold for producing a tank head is disclosed, including a lower mold, an upper mold is arranged on the top of the lower mold, and placement grooves are opened on both sides of the interior of the lower mold, and a trapezoidal block is longitudinally slidably connected to the interior of the placement groove, and a top block is slidably connected to the inner side of the trapezoidal block, and the top of the top block penetrates into the interior of the lower mold. The utility model pushes the top block upward by the first electric push rod and the trapezoidal block, so that the top block pushes the formed raw material out of the lower mold, and then drives the gear, the vertical rod and the movable plate to rotate clockwise around the vertical rod, so that the movable plate pushes the raw material out of the top of the lower mold, so that the raw material is out of the lower mold. The mold for producing a tank head has the advantages of easy demoulding, improves the stability of the mold, and avoids the user manually demoulding and taking out the material, preventing accidental touch from causing hand injuries to the user.

[0005] (2) Application No. / Patent No. 202420216790.6 discloses a mold for producing tank head, which relates to the field of tank head molding technology and aims to solve the problems of inaccurate positioning of the molded parts and inconvenient transportation in the prior art. The mold comprises a lower mold, a pressure ring and an upper mold. A hollow molding cavity is provided in the lower mold, a pressure ring is provided above the lower mold, and a lower mold is provided above the molding cavity. The pressure ring and the lower mold are connected to a stamping device. Guide blocks are evenly provided on the top edge of the lower mold, and a base and a transport seat are provided at the bottom of the lower mold. The utility model provides guide blocks on the top edge of the lower mold to facilitate the guiding and positioning of the molded parts and improve the positioning accuracy. The tank head is stored and transported by a movable transport seat, which improves the convenience of transportation. A pillar is provided on the transport seat and a reset spring is used to connect the sliding sleeve and the pillar to make the force more uniform, thereby ensuring the quality of the finished tank head. The tank head is guided and limited by a detachable guide rod, thereby improving the transportation efficiency of the tank head.

[0006] The applicant analyzed that: (1) the structural design for solving the problem of raw materials being separated from the lower mold is too complicated, and there is no corresponding unloading design, which is especially not applicable to the pressing and production of large head covers; (2) it solves the problem of the transportation of head cover products, but is not suitable for the pressing and production of large and heavy head covers.

[0007] Therefore, based on the above problems, the utility model provides a special mold for producing large heads. Utility Model Content

[0026] A set of lower limit grooves 104 and a set of upper limit protrusions 105 are symmetrically arranged on the opposite surfaces of the lower mold 102 and the upper mold 103.

[0027] A vertical hydraulic cylinder seat 108 is disposed on the base plate 100 and below the lower mold 102.

[0028] Two groups of vertical hydraulic cylinders 109 are symmetrically arranged on the vertical hydraulic cylinder seat 108.

[0029] One end of the vertical hydraulic cylinder 109 is provided with a transition top block 110.

[0030] Two groups of circular through grooves 106 are symmetrically arranged in the lower mold 102.

[0031] One end of the vertical hydraulic cylinder 109 and the transition top block 110 are respectively located in the circular through groove 106;

[0032] Among them, the end face of one end of the transition top block 110 has the same structure as the end face of the circular through groove 106 in the lower mold 102. The transition top block 110 is alloy stainless steel. In the original state, the upper end face of the transition top block 110 is flush with the end face of the circular through groove 106, which is used to seal the outer wall of the head blank 120 during pressing to prevent deformation.

[0033] During the forming and pressing process: the head blank 120 is placed in the lower mold 102, and the upper mold 103 is pressed downward to form the head blank 120 in the lower mold 102, and at the same time, the upper limit protrusion 105 is embedded in the lower limit groove 104 to achieve the relative horizontal limit of the upper mold 103 and the lower mold 102 (to prevent large horizontal displacement), and complete the rapid and accurate forming and pressing of the head blank 120;

[0034] Unloading (demolding) after pressing and forming: start the two groups of vertical hydraulic cylinders 109 respectively, and then the transition top blocks 110 on the two groups of vertical hydraulic cylinders 109 move upward respectively, so that the pressed head blank 120 is quickly and safely ejected from the lower mold 102 (the outer wall of the contact surface between the transition top block 110 and the pressed head blank 120 forms a quadrilateral), and then move it away from the mold 102. Embodiment 2

[0035] On the basis of the first embodiment, the special mold for producing large heads also includes an intermediate circular through groove 107 arranged in the lower mold 102 and located between the two groups of circular through grooves 106, an intermediate vertical hydraulic cylinder 111 arranged in the vertical hydraulic cylinder seat 108 and located between the two groups of vertical hydraulic cylinders 109, and an intermediate transition top block 112 arranged at one end of the intermediate vertical hydraulic cylinder 111 (the intermediate transition top block 112 is alloy stainless steel, and the upper end face of the intermediate transition top block 112 is flush with the end face of the intermediate circular through groove 107 in the original state, which is used to block the outer wall of the head blank 120 during pressing to prevent deformation);
