Description

Technical Field

[0001] The utility model belongs to the technical field of hot presses, and in particular relates to a hot press with a reverse floating mechanism for an advance and retreat mold track. Background Art

[0002] A hot press is a device used to process materials under high temperature and pressure, such as plastics, rubber, composite materials, fiberboard, wood, metal, etc. The working principle of a hot press is to use its internal heating system and pressure system to heat the material to the required temperature and apply a certain pressure to achieve the purpose of welding, molding, curing or changing the physical properties of the material.

[0003] Friction material hot presses are generally powder pressing and forming processes. The hot presses have a die advance and retreat mechanism. Traditional die advance and retreat mechanisms generally use a fixed track mechanism to prevent the mold from sticking to the product and to prevent the mold from being unable to detach when opening the mold, causing defects in the product. In this application, in order to cooperate with the working mode of the proportional pressure cylinder on the hot press, a reverse floating mechanism for the die advance and retreat track is designed. Even if there is a problem with the product powder in the early stage of pressing, damage to the mechanism caused by insufficient powder can be avoided. Utility Model Content

The reverse floating mechanism utilizes the compressible characteristics of the spring, and is matched with a sliding plate, a pressure plate, and equal-height column bolts to allow the sliding plate in each cavity to operate independently. The reverse floating space design has a maximum distance of 10 mm. Even if problems occur with the product powder in the early stage of pressing, damage to the mechanism caused by insufficient powder can be avoided.

[0021] See also Figures 1 to 5 The present application relates to a hot press having a reverse floating mechanism for advancing and retreating mold tracks, comprising a frame having a guide column 3, the hot press being provided with a base mechanism 2, a track and mold mechanism 4, the track and mold mechanism 4 comprising a plurality of regularly distributed mold units 41, each of the mold units 41 being provided with a corresponding sliding plate 42 below, each of the sliding plates 42 being provided with step portions 424 on both sides of its moving direction; a plurality of the sliding plates 42 being horizontally distributed in two rows in the moving direction, the corresponding step portions 424 of adjacent sliding plates 42 being provided with a central floating mechanism 43, the central floating mechanism 43 being provided with a plurality of elastic support units, the elastic support units being used to apply an elastic support force between the sliding plates 42 and the mold units 41, the structure being highly practical, and being able to avoid damage to the mechanism due to insufficient powder even if problems occur with the product powder in the early stage of pressing.

[0022] Specifically, in the present application, the track and mold mechanism 4 includes four mold units 41 distributed in four directions, and four sliding plates 42 correspondingly arranged under each mold unit 41. The structure is reasonably arranged, and each mold unit is provided with a powder cavity for placing powder for hot pressing. The support rod 451 is an equal-height stud, and the maximum floating distance of the central floating mechanism 43 is 10 cm, which can well meet the use requirements.

[0023] From the attached Figure 3 and attached Figure 4 It can be seen that the central floating mechanism 43 is: a strip structure with a T-shaped cross-section, with three to five elastic support units evenly distributed on it; the two sides of the T-shaped strip structure are symmetrically mounted on the step portions 424 of the adjacent sliding plates 42. This structure is a symmetrical structure with uniform force transmission and high stability during operation.

[0024] In addition, in one embodiment of the present application, a side floating mechanism 44 is provided on the step portion 424 on the outer side of the sliding plate 42; the side floating mechanism 44 is provided with a plurality of elastic support units, and the elastic support unit includes a movable support rod 451 and an elastic member 452 sleeved on the support rod 451. The side floating mechanism 44 is a strip-shaped structure with a convex edge on one side facing the sliding plate 42, and three to five elastic support units are evenly distributed thereon; the convex edge is mounted on the step portion 424 on the outer side of the sliding plate 42. The elastic support unit on the side floating mechanism 44 is used to apply an elastic support force between the sliding plate 42 and the pressure unit.

[0025] In the above description of the specific scheme in the present application, other structures not described may be conventional structures and technologies in the prior art. The working principle of the hot press in the present application is as follows: before the friction material is pressed, the powder of the friction material needs to be poured into the cavity of the mold unit 41, and then the mold sending mechanism is actuated to send it to the main machine, and the pressing begins after it reaches the position.

[0026] The reverse floating mechanism of the advance and retreat mold track is designed to prevent the volume difference of the powder from being too large when the powder is filled. During the pressing process, the equal pressure cylinder and the sliding plate will be pushed upward to a higher stroke. However, without a reverse floating mechanism, the advance and retreat mold track will be damaged. In this application, a central floating mechanism 43 (reverse floating mechanism) is used to allow the sliding plate to have space to float upward, thus avoiding the above-mentioned situation. This mechanical equal pressure mechanism solves the problem of difficult installation and debugging of the hydraulic type, and has the characteristics of simple structure and easy installation. The reverse floating mechanism is designed to solve the problem of the traditional track design that cannot be reversely floated, thereby reducing the damage rate of the equipment.

[0027] Traditional mold advance and retreat mechanisms generally use fixed track mechanisms to prevent the mold from sticking to the product and to prevent the mold from being unable to detach when opening the mold, which in turn causes defects in the product. In order to cooperate with the working mode of this isobaric pressure cylinder, the present application provides a center floating mechanism (reverse floating mechanism) on the mold advance and retreat guide track. By utilizing the compressible characteristics of the elastic member 452 (spring), the center floating mechanism 43 and the design of an elastic support unit with equal-height column bolts, each mold unit 41 can independently operate the corresponding sliding plate 42 and the center floating mechanism 43. Even if there is a problem with the product powder in the mold unit 41 in the early stage of pressing, the center floating mechanism 43 can provide support force to avoid damage to the mechanism due to insufficient powder.

[0028] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
