Description

Technical Field

[0001] This utility model belongs to the technical field of dental prosthesis base production equipment, and specifically relates to a double-layer press. Background Technology

[0002] In the manufacturing process of denture bases, a corresponding double-layer press is required to press and shape the denture bases. While existing double-layer presses can meet the basic requirements for pressing denture bases and can prevent surface damage by adding a protective layer to the bottom of the pressing block, they typically use a spring-loaded limiting structure to limit the denture base. The limiting effect of this structure relies on the spring's rebound effect. However, after a period of use, the spring may not fully rebound, affecting its limiting effect and thus preventing the denture base from being effectively clamped and limited, causing significant inconvenience for users.

[0003] For example, utility model patent CN217525423U discloses a double-layer press. In the technical solution of this patent document, a limiting mechanism is provided on the surface of the base. The limiting mechanism includes a limiting seat, a placement groove, a connecting rod, a clamping block, and a spring. The limiting seat is set on the surface of the base, and a placement groove is opened in the middle of the limiting seat. During use, the clamping block is first pushed outward, and then the denture base is placed inside the placement groove on the limiting seat. After the clamping block is loosened, it can automatically reset to clamp the outside of the denture base. The device relies strictly on the spring's rebound effect to limit and clamp the denture base. After a period of use, the spring is likely to fail to fully reset, which will cause it to be unable to continue to stably clamp and limit the denture base, thus failing to fully meet people's usage needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a double-layer press, which not only meets the basic requirement of pressing denture bases, but also enables the positioning structure to stably and accurately clamp and limit the denture bases for a long time, thereby fully meeting people's usage needs.

The design of the second guide hole and the second guide rod ensures that the limiting clamp plate remains horizontal during movement, preventing deviation and thus ensuring the limiting accuracy; and can also prevent the second telescopic push rod from being easily damaged by terrain deformation.

[0010] As a further improvement of this utility model, the first telescopic push rod is detachably connected to the extrusion block, and the second telescopic push rod is detachably connected to the limiting clamping plate. The detachable connection design between the first telescopic push rod and the extrusion block, and between the second telescopic push rod and the limiting clamping plate, makes the equipment easy to maintain and clean, and also facilitates the adjustment or replacement of parts according to actual needs.

[0011] As a further improvement of this utility model, a fixing plate is also provided at the bottom of the base, and the fixing plate is provided with fixing holes for installing fixing bolts. The design of the fixing plate and fixing bolts ensures the stability of the entire equipment during operation, reduces errors caused by vibration, extends the service life of the equipment, and improves work safety.

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 3 As shown in Figure 4, a double-layer press includes a base 101, a plurality of vertical rods 102 are provided on the base 101, a top plate 103 is provided on the plurality of vertical rods 102, a first telescopic push rod 104 is vertically provided on the top plate 103, the fixed end of the first telescopic push rod 104 is connected to the top plate 103, the output shaft of the first telescopic push rod 104 passes through the top plate 103, and a first through hole is provided on the top plate 103 and sleeved on the outside of the output shaft of the first telescopic push rod 104;

[0024] A pressing block 105 is provided at the lower end of the output shaft of the first telescopic push rod 104. A first protective plate 106 is detachably provided at the bottom of the pressing block 105. Vertical plates 107 are provided on the left and right sides of the top of the base 101. A second telescopic push rod 108 is provided horizontally on each of the two vertical plates 107. The fixed end of the second telescopic push rod 108 is connected to the outer wall of the vertical plate 107. The output shaft of the second telescopic push rod 108 passes through the vertical plate 107.

[0025] The output shaft of the second telescopic push rod 108 is provided with a limit clamp 109 at its end, and a second protective plate 110 is detachably provided on the inner end of the limit clamp 109.

[0026] The worker first activates two horizontally positioned first telescopic push rods 104, causing their output shafts to extend a certain length, pushing the limiting clamps 109 to the corresponding positions. The two limiting clamps 109 together form a guide cavity for precisely placing the denture base. The denture base is then passed through the guide cavity and placed onto the base 101. Due to the existence of the guide cavity, the denture base can be precisely positioned, ensuring positional accuracy during subsequent pressing processes.

[0027] The first telescopic push rod 104 on the top plate 103 starts to work, and its output shaft extends downward, driving the pressing block 105 to move downward and press the denture base; the first protective plate 106 at the bottom of the pressing block 105 protects the base material from direct mechanical damage; at the same time, the second telescopic push rod 108 continues to maintain the position of the limiting clamp 109, ensuring that they always surround the base material, providing stable lateral support and preventing the material from shifting during the pressing process.

[0028] Then, the output shaft of the first telescopic push rod 104 is driven to shorten upward by a certain length, which drives the pressing block 105 and the first protective plate 106 to reset upward; then the output shaft of the second telescopic push rod 108 can be driven to shorten by a certain length, which drives the limiting clamp 109 and the second protective plate 110 to reset laterally, and then the denture base can be easily removed from the base 101.

[0029] According to another embodiment of the present invention, such as Figure 3 As shown, the side end of the extrusion block 105 is provided with a first connecting slot 111, and the side end of the first protective plate 106 is provided with a first connecting plate 112 that engages with the first connecting slot 111. The first connecting slot 111 is provided with a first connecting bolt 113 for screwing the first connecting plate 112, and the first connecting plate 112 is provided with a first threaded connection hole for screwing the first connecting bolt 113.

The second connecting bolt 116 is a hand-tightening bolt. By engaging the second connecting plate 115 with the second connecting slot 114, and then driving the second connecting bolt 116 through the side wall of the second connecting slot 114 and screwing it into the second threaded connection hole, the limiting clamp 109 and the second protective plate 110 can be flexibly fixed.

[0031] According to another embodiment of the present invention, such as Figure 1 and 2 As shown, a first guide hole 201 is vertically provided on the top plate 103, and a first guide rod 202 that is inserted into the first guide hole 201 is provided on the extrusion block 105. The output shaft of the second telescopic push rod 108 extends and retracts vertically.
