Description

Technical Field

[0001] The utility model relates to the technical field of the necking of heat preservation cups, and specifically, to a mold for necking a stainless steel heat preservation cup. Background Technique

[0002] In the field of manufacturing stainless steel heat preservation cups, in order to improve the heat preservation performance of the products and the hand feeling during use, it is usually necessary to perform necking treatment on the cup mouth of the heat preservation cup. The necking process mainly refers to compressing the mouth part of a pre-formed cylindrical or pipe blank through a specific mold, so that the cup mouth forms a certain inclination angle or a closed mouth shape, so as to meet different design requirements. This process is crucial for ensuring the sealing performance and aesthetics of the heat preservation cup.

[0003] When the traditional necking device processes the heat preservation cup, the heat preservation cup is usually placed inside the mold, and then the necking effect is achieved by manually screwing multiple fixing screws. However, this method not only has a cumbersome operation, and a large amount of time is required to screw the screws one by one, resulting in low work efficiency; moreover, uneven force is likely to occur during the manual operation process, which may affect the flatness of the cup mouth of the heat preservation cup and the overall quality. Therefore, how to simplify the necking operation process, improve the processing efficiency of the heat preservation cup, and ensure the consistency and accuracy of necking has become an important research direction. For the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0004] Aiming at the problems in the related technology, the utility model proposes a mold for necking a stainless steel heat preservation cup to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] For this reason, the specific technical solution adopted by the utility model is as follows:

[0006] A mold for necking a stainless steel heat preservation cup includes a support base. An installation hole is opened on the surface of the support base. A transmission ring is fixedly connected to the inner wall of the installation hole. A telescopic groove is opened on the surface of the transmission ring. An extrusion block is slidably installed inside the telescopic groove. A necking ring is fixedly installed at one end of the extrusion block. A transmission worm gear is rotatably connected to the surface of the transmission ring. A support frame is fixedly installed on the surface of the transmission worm gear. An extrusion roller is rotatably installed on one side of the support frame. A pressure-receiving inclined surface is opened at one end of the extrusion block. The extrusion roller is rotatably installed on one side of the pressure-receiving inclined surface. A transmission motor is fixedly installed on one side of the surface of the support base. A transmission worm is fixedly connected to the transmission shaft of the transmission motor. The transmission worm is meshed with the transmission worm gear.

[0007] Furthermore, in order to realize the automatic shrinkage and reset of the extrusion block and the necking ring after being pressured to move, adjusting plates are fixedly connected to the upper and lower sides of the extrusion block. A reset spring is fixedly installed on the surface of the adjusting plate. The end of the reset spring is fixedly connected to the inner wall of the transmission ring.

[0008] Furthermore, in order to enable the replaceability of the locking ring on the extrusion block, a positioning groove is formed on one side surface of the necking ring, and one end of the extrusion block is slidably installed in the positioning groove.

[0009] Furthermore, in order to fixedly install the necking ring on one side of the extrusion block to prevent it from falling off, positioning rings are fixedly connected to both sides of the surface of the extrusion block, and the positioning rings are fixedly installed on the necking ring through bolts.

[0010] Furthermore, in order to facilitate the fixed installation of the support base at the working point, stabilizing plates are fixedly connected to both sides of the surface of the support base, and positioning holes are formed on the surfaces of the stabilizing plates.

[0011] Furthermore, in order to stably support the driving worm, a support plate is fixedly connected to one side of the surface of the support base, and one end of the driving worm is rotatably connected to the support plate.

[0012] Furthermore, in order to supply power to the driving motor and control its rotation, a power interface is formed on one side of the surface of the support base, and a control switch is fixedly installed on one side of the power interface.

[0013] The beneficial effects of the present utility model are as follows: The driving motor drives the driving worm to rotate, causing the driving worm to drive the driving worm gear to rotate on the surface of the transmission ring. Furthermore, each extrusion roller on the surface of the driving worm gear pushes the extrusion block. The pushed extrusion block drives two pairs of necking rings to approach each other, automatically squeezing and necking the thermos cup that needs to be necked. The design of this mold ensures that the pressure distribution applied to the thermos cup during the necking process is more uniform, avoiding deformation problems caused by excessive local stress in the traditional method, thus ensuring the processing accuracy of the mouth of the thermos cup and the product quality. At the same time, while effectively reducing the labor intensity of the operator, the efficiency of the necking process of the thermos cup is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
