Description

Technical Field

[0001] The invention relates to a base for molding equipment, in particular to a rotatable base for a molding machine. Background Art

[0002] At present, for the molding of some plastic materials, large-scale special molding equipment (mass production) or small-scale molding devices (small-scale production) are usually used. This type of large-scale molding equipment is mainly suitable for factories, and its purchase cost and use cost are high. For small-scale molding devices, although the manufacturing cost and use cost are low, their structure is relatively simple and can only be processed in one piece, which makes their work efficiency very low. For pastry production in family workshops, the use of conventional small-scale molding devices has seriously restricted the improvement of their productivity and caused a waste of production costs. Therefore, how to carry out efficient production on small-scale molding devices has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a rotatable base for a molding machine which has a simple structural design, quick and convenient operation, good reliability in use and capable of efficient production.

[0004] In order to solve the above technical problems, the molding machine of the present invention has a rotatable base, including a base located on the front side of the molding machine body and a mold mounted on the base for cooperating with the die of the molding machine body. A rotating table is arranged in the middle of the base, and a transmission mechanism for driving the rotating table to rotate and reverse is arranged in the base. An operating handle connected to the transmission mechanism is installed on the side of the base. Two processing stations are arranged on the mold. The mold is installed on the rotating table and can rotate the rotating table driven by the transmission mechanism to rotate the two processing stations and interchange them, thereby selectively making one of the processing stations correspond to the position of the upper mold base.

[0005] The transmission mechanism comprises two mutually meshing bevel gears, wherein one bevel gear is mounted on a power input shaft, and the other bevel gear is connected to a power output shaft, and the rotating platform is fixedly connected to the power output shaft.

[0006] The rotating table includes a card seat with a T-shaped card slot and a mounting slot arranged at the bottom of the card seat, a mounting plate matching the mounting slot is arranged on the top of the power output shaft, and a T-shaped block for card-matching with the T-shaped card slot is arranged at the bottom of the mold.

[0007] The base is provided with a lower cavity for accommodating the transmission mechanism and an upper cavity for accommodating the rotating table. The base is provided with a mounting guide groove which penetrates the upper cavity. The T-block can enter the T-slot of the clamping seat through the mounting guide groove.

[0008] A bottom bearing hole is arranged on the wall surface of the lower cavity, and a bottom bearing limited in the bottom bearing hole is installed on the power output shaft.

[0009] An inner wall bearing hole and an outer wall bearing hole matching the inner wall bearing hole are arranged on the side wall of the base, and an inner wall bearing limited in the inner wall bearing hole and an outer wall bearing limited in the outer wall bearing hole are installed on the power input shaft.

[0010] The outer wall bearing hole is a stepped hole, and a rotation limit plate located outside the outer wall bearing is fixedly mounted on the power input shaft. A limiting step surface is arranged at the outermost stepped hole, and a limiting boss cooperating with the limiting step surface is arranged on the rotation limit plate.

[0011] The power input shaft is also provided with a cover plate which is located outside the rotation limiting disk and is used for fixed installation with the base.

[0012] The rotation limiting plate is positioned and installed by a limiting sleeve fixedly installed on the power input shaft.

[0013] The advantages of the present invention are: (1) A mold with two processing stations is placed on a base, a rotating table is arranged in the middle of the base, and a transmission mechanism for driving the rotating table to rotate and reverse is arranged in the base. After the mold is installed on the rotating table, the rotating table can be rotated under the drive of the transmission mechanism, and then the two processing stations are rotated and exchanged, so that one of the processing stations is selectively made to correspond to the position of the upper mold base, which means that one processing station can be operated on another processing station while it is in a processing state, which greatly saves operation time and improves work efficiency.

[0014] (2) The rotary table is designed as a specific structure of a card seat with a T-shaped card slot and an installation slot. On the one hand, the card seat can be used to directly connect with the power output shaft. On the other hand, the T-shaped card slot can be directly matched with the T-shaped block of the mold to achieve quick installation of the mold, thereby greatly improving the convenience of operation. (3) By setting up a transmission mechanism composed of two mutually meshing bevel gears and installing the transmission mechanism in the base through different bearings, the transmission method is simple, the transmission is reliable, and the stability is good, which greatly improves the reliability of use.

[0015] (4) By means of a rotation limit plate with a limit boss fixedly mounted on the power input shaft and a limit step surface provided at the outermost stepped hole and connected to the rotation limit plate, the rotation angle of 180° can be controlled by the cooperation between the limit boss and the limit step surface, thereby further improving the reliability of operation.

[0016] (5) The entire structure is simple and compact, with few transmission links, high transmission accuracy, and easy assembly and disassembly. It is easy to install and maintain, has low manufacturing costs, and is reliable in use, ensuring efficient and high-quality production. BRIEF DESCRIPTION OF THE DRAWINGS
