Description

Technical Field

[0001] The utility model relates to a rubber ring processing tool, in particular to a rubber ring pneumatic mold releasing tool based on negative pressure attraction. Background Art

[0002] A rubber ring is an annular product made of rubber material, usually used for seals, gaskets or connecting parts. They are widely used in mechanical equipment, automobiles, home appliances and construction to prevent liquid or gas leakage, reduce vibration or provide other functions. When the rubber ring is processed, burrs will appear on the inner and outer rings. In order to improve the dimensional accuracy of the rubber ring, the burrs on the inner and outer rings need to be removed. When removing the burrs on the rubber ring, the rubber ring needs to be limited and fixed. In order to facilitate the fixation of the rubber ring, a pneumatic mold release tooling with negative pressure suction will be used to limit and fix the rubber ring.

[0003] The current pneumatic mold releasing tooling for rubber rings based on negative pressure suction can only be used for adsorption of rubber rings of one size on the mold table. When the pneumatic mold releasing tooling is used on rubber rings of different sizes, the mold table needs to be replaced to adapt it. As a result, when processing rubber rings of different sizes, the assembly time of the pneumatic mold releasing tooling is prolonged and the use effect is not good. Therefore, there is an urgent need for a pneumatic mold releasing tooling that can be used for rubber rings of multiple sizes. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail various exemplary embodiments, features and aspects of the present application with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration". Any embodiment described herein as "exemplary" should not necessarily be construed as superior or better than other embodiments.

[0027] In addition, for a better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some of these specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0028] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, a pneumatic mold releasing tool for a rubber ring based on negative pressure suction includes:

[0029] A mold plate 3, the mold plate 3 is rotatably connected to the machine base 1, and a driving member 2 is fixedly arranged on one side of the machine base 1, and the driving member 2 abuts against the mold plate 3;

[0030] A suction plate 4, the suction plate 4 is rotatably arranged in the cavity of the mold plate 3;

[0031] A limiting member 5, the limiting member 5 is arranged on the suction plate 4, and the limiting member 5 is inserted into the mold plate 3.

[0032] In this embodiment, when performing negative pressure suction on the rubber ring, according to the size of the rubber ring, the suction plate 4 is rotationally adjusted in the mold plate 3. By squeezing the two paddles 502, the distance between the two paddles 502 is reduced. When squeezing the two paddles 502, the spring 504 between them will be squeezed and contracted and maintain a resilient force. When squeezing the two adjusting plates 501, the limiting pins 503 on the two adjusting plates 501 will be disengaged from the insertion in the limiting holes opened on the sliding limiting frame 304. Since the limiting member 5 is arranged on the T-shaped block 403, when the limiting pin 503 is disengaged from the insertion in the limiting hole, the T-shaped block 403 can be slidably adjusted in the sliding limiting frame 304, as Figure 5A plurality of vent holes 402 provided on the suction disc 4 are arranged in a spiral pattern. When one group of vent holes 402 coincides and communicates with the suction holes 303 of the corresponding diameter, the remaining groups of vent holes 402 will abut against the solid part at the top of the cavity of the mold disc 3, and the ports of the remaining groups of vent holes 402 achieve a sealing effect. After adjusting the position of the T-shaped block 403, release the pinched paddle 502, and the spring 504 rebounds, causing the limit pin 503 to be inserted into the corresponding limit hole, so that the position of the suction disc 4 in the mold disc 3 is kept positioned. The mold disc 3 is rotatably connected to the rotating seat on the machine base 1, and the joint 401 is rotatably sleeved on the mold disc 3 and is connected to the connecting pipe of an external vacuum pump, meeting the adjustment requirements during negative pressure adsorption and pressure relief demolding. Place the rubber ring in the embedded suction groove 302 of the corresponding diameter. Through the negative pressure adsorption of an external vacuum pump, the suction holes 303 generate negative pressure suction, so that the rubber ring is tightly adsorbed in the embedded suction groove 302, meeting the negative pressure adsorption use of the rubber ring. By the driving wheel of the driving member 2 abutting against the anti-slip pattern 301 to drive the mold disc 3 to rotate on the machine base 1, the rotation use of the negatively adsorbed rubber ring can be realized, so as to meet the subsequent trimming operation of the rubber ring and ensure the use effect. Through the cooperative design, when processing rubber rings of different diameters by negative pressure adsorption, the applicability can be improved, and frequent replacement of molds of different applicable sizes, which delays the processing efficiency, can be avoided. What is not described in detail in this solution is the prior art, so it will not be elaborated too much.

[0033] As a further solution of the present utility model, the outer wall of the bottom of the mold disc 3 is provided with an anti-slip pattern 301. A plurality of embedded suction grooves 302 are opened at the top of the mold disc 3. The diameters of the plurality of embedded suction grooves 302 gradually decrease from the outside to the inside. A plurality of suction holes 303 are equidistantly arranged in a circular array at the part of the mold disc 3 where the embedded suction grooves 302 are located. One side of the mold disc 3 is fixedly connected with a sliding limit frame 304. The upper and lower sides of the sliding limit frame 304 are provided with limit holes having the same number as the embedded suction grooves 302. The mold disc 3 is rotatably connected to the rotating seat provided on the machine base 1, and the anti-slip pattern 301 is arranged in abutment with the driving wheel of the driving member 2.

[0034] In this embodiment, a plurality of embedded suction grooves 302 of different diameters at the top of the mold disc 3 can enable the mold disc 3 to be applicable to the placement and negative pressure adsorption operations of a variety of rubber rings of different sizes, improving the applicability of the mold disc 3. The mold disc 3 is rotatably connected to the machine base 1. Therefore, when the driving member 2 abuts against the anti-slip pattern 301, the mold disc 3 can be driven to rotate on the machine base 1, so that a series of operations such as rotation trimming can be performed on the rubber ring negatively adsorbed on the mold disc 3, meeting the processing use requirements.

[0035] As a further solution of the utility model, the suction disc 4 is provided with a hollow cavity. A connector 401 is fixedly arranged at the central part of the bottom of the suction disc 4. A plurality of groups of ventilation holes 402 are arranged in an annular array at the top of the suction disc 4. The plurality of groups of ventilation holes 402 are arranged in a spiral arrangement. A T-shaped block 403 is integrally formed on one side of the suction disc 4. An activity groove and insertion holes on the upper and lower sides are formed in the T-shaped block 403. The connector 401 is rotatably sleeved on the die plate 3. The top of the ventilation hole 402 is slidably attached to the top of the cavity of the die plate 3. The ventilation hole 402 is communicated with the suction hole 303. The T-shaped block 403 is slidably connected in the sliding limit frame 304.

[0036] In this embodiment, the connector 401 is rotatably connected to the pipeline of an external vacuum pump, which is a prior art and will not be elaborated here. Through the rotational connection, when the die plate 3 rotates, the suction disc 4 can maintain the sealing connection requirement, ensuring the operation control of negative pressure adsorption and pressure relief. When the suction disc 4 is rotated, the suction disc 4 can be rotated and adjusted inside the die plate 3 to control the connection between the ventilation holes 402 with different combined diameters and the suction holes 303 with corresponding diameters. When one group of ventilation holes 402 is communicated with the suction hole 303, the remaining multiple groups of ventilation holes 402 abut against the top of the cavity of the die plate 3, so as to seal the ports of the remaining groups of ventilation holes 402. During negative pressure adsorption, the suction hole 303 communicated with the ventilation hole 402 can perform normal air intake and air release operations, ensuring the use effect and simultaneously meeting the negative pressure adsorption use of rubber rings with multiple different sizes on the die plate 3.

[0037] As a further solution of the utility model, the limiting member 5 includes an adjusting plate 501, a dial 502, a limiting pin 503 and a spring 504. The adjusting plates 501 are symmetrically arranged. A dial 502 is fixedly connected to one side of the adjusting plate 501. A limiting pin 503 is fixedly connected to the central part of the adjusting plate 501. The limiting pins 503 on the two adjusting plates 501 are arranged in opposite directions. A spring 504 is fixedly connected between the two adjusting plates 501. The two adjusting plates 501 are slidably connected in the activity groove formed in the T-shaped block 403. The limiting pin 503 is slidably inserted into the insertion hole on the T-shaped block 403. The limiting pin 503 is inserted into the limiting hole on the sliding limit frame 304.

[0038] In this embodiment, through the connection of the limiting member 5 to the suction disc 4 and the insertion of the limiting member 5 into the corresponding limiting holes on the sliding limiting frame 304, the rotational state of the suction disc 4 on the mold disc 3 can be conveniently adjusted. When performing negative pressure adsorption operations on rubber rings of different sizes, the suction disc 4 can be conveniently rotated inside the mold disc 3. When the limiting pin 503 is inserted into the same number of limiting holes as the embedded suction grooves 302, each time it is inserted into a limiting hole, the suction disc 4 can be rotated inside the mold disc 3, enabling one set of suction holes 303 to communicate with the ventilation holes 402 for adsorption use, and enabling the suction holes 303 of the corresponding size to communicate with the ventilation holes 402 to achieve the operation of negative pressure adsorption, thereby improving the overall applicability.
