Description

Technical Field

[0001] This utility model relates to the field of rubber production equipment technology, and in particular to a press for producing flame-retardant chloroprene rubber. Background Technology

[0002] Flame-retardant neoprene rubber is often used as a sealant and anti-corrosion lining. The flame-retardant neoprene rubber in the mold is pressurized by a press to form the required structure and shape.

[0003] The press drives the upper and lower molds to close and carry out the production of flame-retardant neoprene rubber. Personnel work below the upper mold to place the flame-retardant neoprene rubber raw materials and pick up the finished products. In daily production, in order to improve efficiency, the placement of flame-retardant neoprene rubber raw materials or the picking up of finished products may also occur during the upward or downward movement of the upper mold. If the personnel's arms are not retracted in time, there will be a problem of crushing and injuring the personnel. Summary of the Invention

[0004] This disclosure relates to a press for producing flame-retardant chloroprene rubber. An annular moving belt moves the lower mold base below the upper mold lifting frame for pressurizing the flame-retardant chloroprene rubber. The annular moving belt also moves the lower mold base outside the upper mold lifting frame for placing the flame-retardant chloroprene rubber raw material and retrieving the finished product. This makes the work safer, eliminating the need for personnel to place the flame-retardant chloroprene rubber raw material and retrieve the finished product below the upper mold lifting frame, and preventing injuries from personnel's arms not being retracted in time when the upper mold lifting frame descends.

[0005] In a first aspect, this disclosure provides a press for producing flame-retardant chloroprene rubber, specifically comprising: a main base, a middle lifting frame, and a lower mold base. The middle lifting frame is provided on the upper part of the main base, and the lower mold base is provided above the middle lifting frame. Outer limiting slide columns are fixedly provided at the four outer corners of the main base. The outer limiting slide columns and the upper mold lifting press are axially slidably connected. A top frame is fixedly provided at the top of the outer limiting slide columns, and a pressurizing telescopic cylinder is fixedly provided at the top of the top frame. A middle support platform protrudes from the top of the main base.

[0006] In at least some embodiments, the telescopic rod of the pressurized telescopic cylinder is fixedly connected to the upper mold lifting frame, and the upper mold lifting frame is located above the lower mold base.

[0007] In at least some embodiments, rotating electric drive rollers are arranged in an array on both sides of the central lifting frame. The electric drive rollers are driven to rotate by a motor. The electric drive rollers and the annular moving belt are tightly engaged and connected. Lower support springs are fixedly arranged on both sides of the bottom of the central lifting frame, and lower connecting slide columns are fixedly arranged on both sides of the bottom of the central lifting frame.

[0008] In at least some embodiments, the lower end of the lower connecting slide is screwed with a lower limit nut, the lower connecting slide and the lower connecting frame are slidably connected through each other, the lower support spring supports the middle lifting frame and the lower mold seat to move upward, the lower mold seat and the middle support platform are separated, and the annular moving belt drives the suspended lower mold seat to move.

[0009] In at least some embodiments, the lower limit nut is located below the lower connecting frame, and the lower limit nut limits the upward movement range of the lower connecting slide, and the lower connecting frame and the main base are fixedly connected.

[0010] In at least some embodiments, a lower mold base is fixedly provided at intervals on the upper part of the annular moving belt, and the lower mold base is located above the middle support platform.

[0011] In at least some embodiments, the upper mold lifting and pressing frame moves down and presses down the lower mold seat, the lower mold seat and the middle lifting frame move down synchronously, the bottom of the lower mold seat and the top of the middle support platform are in close contact, and the middle support platform supports the lower mold seat when pressure is applied.

[0012] This utility model provides a press for the production of flame-retardant chloroprene rubber, which has the following beneficial effects:

[0013] The circular conveyor belt moves the lower mold base below the upper mold lifting frame for the pressurization production of flame-retardant neoprene rubber. The circular conveyor belt also moves the lower mold base to the outside of the upper mold lifting frame for the placement of flame-retardant neoprene rubber raw materials and the retrieval of finished products. This makes the work safer, eliminating the need for personnel to place flame-retardant neoprene rubber raw materials and retrieve finished products below the upper mold lifting frame, and preventing personnel from being injured by their arms not being retracted in time when the upper mold lifting frame moves down.

[0014] The top of the annular moving belt is equipped with multiple lower mold seats. While one lower mold seat is being pressurized, personnel can place raw materials or remove finished products from another lower mold seat. Compared with a single lower mold seat, this reduces processing gaps and improves processing efficiency.

[0015] After pressurization is completed, the lower support spring supports the lifting frame and the lower mold base, which move upwards. The lower mold base separates from the middle support platform, and the lower mold base moves in the air. The movement resistance of the lower mold base is smaller, which avoids the situation where the movement resistance is large when the lower mold base moves along the top of the middle support platform.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example 1: Please refer to Figures 1 to 6 :

[0031] This utility model proposes a press for producing flame-retardant chloroprene rubber, comprising: a main base 1, a middle lifting frame 2, and a lower mold base 3. Four outer limiting sliding columns 101 are fixedly installed at the four outer corners of the main base 1. The outer limiting sliding columns 101 and the upper mold lifting frame 102 are axially slidably connected. A top frame 103 is fixedly installed at the top of the outer limiting sliding columns 101. A pressure telescopic cylinder 104 is fixedly installed at the top of the top frame 103. A middle support platform 105 protrudes from the top of the main base 1. The telescopic rod of the pressure telescopic cylinder 104 is fixedly connected to the upper mold lifting frame 102. The upper mold lifting frame 102 is located above the lower mold base 3. The upper part is provided with a middle lifting frame 2. Rotating electric drive rollers 201 are arranged in an array on both sides of the middle lifting frame 2. The electric drive rollers 201 are driven by a motor to rotate. The electric drive rollers 201 and the annular moving belt 202 are tightly engaged and connected. Lower support springs 203 are fixedly provided on both sides of the bottom of the middle lifting frame 2. Lower connecting slide columns 204 are fixedly provided on both sides of the bottom of the middle lifting frame 2. The lower limit nut 205 is located below the lower connecting frame 206. The lower limit nut 205 limits the upward movement range of the lower connecting slide column 204. The lower connecting frame 206 is fixedly connected to the main base 1. A lower mold base 3 is provided above the middle lifting frame 2.

[0032] In this embodiment, a lower limit nut 205 is screwed to the lower end of the lower connecting slide column 204. The lower connecting slide column 204 and the lower connecting frame 206 are slidably connected through each other. The lower end of the lower support spring 203 is fixedly connected to the lower connecting frame 206. The lower support spring 203 supports the middle lifting frame 2 and the lower mold seat 3 to move upward. The lower mold seat 3 and the middle support platform 105 are separated. The annular moving belt 202 drives the suspended lower mold seat 3 to move. The moving resistance of the lower mold seat 3 is smaller. The lower mold seat 3 will not increase the moving resistance of the annular moving belt 202.

[0033] In this embodiment of the present disclosure, a lower mold seat 3 is fixedly provided at intervals on the upper part of the annular moving belt 202. The lower mold seat 3 is located above the middle support platform 105. Personnel can place raw materials or take out finished products on the other lower mold seat 3 while one lower mold seat 3 is pressurized. Compared with a single lower mold seat 3, the processing gap and waiting time are reduced.

[0034] In this embodiment, the upper mold lifting pressure frame 102 moves down and presses down the lower mold seat 3. The lower mold seat 3 and the middle lifting frame 2 move down synchronously. The bottom of the lower mold seat 3 and the top of the middle support platform 105 are in close contact. The middle support platform 105 supports the lower mold seat 3 when it is pressurized. The middle lifting frame 2 and the electric drive roller 201 do not bear pressure, which also avoids the situation where the electric drive roller 201 bears the pressure and the relevant bearing components are easily damaged.

[0035] In Example 2, based on Example 1, when the pressure telescopic cylinder 104 is in the lower position and the upper mold lifting frame 102 is fixed, the pressure telescopic cylinder 104 pushes the lower mold seat 3 to move upward and close to the upper mold lifting frame 102. The lower support spring 203, lower connecting slide 204, lower limit nut 205, and lower connecting frame 206 can be omitted, and the middle lifting frame 2 is directly fixedly connected to the main base 1.

[0036] The working principle of this embodiment is as follows: The lower mold base 3 and the upper mold lifting pressure frame 102 are used to install the upper and lower molds. The lower mold base 3, which is arrayed at the top of the annular moving belt 202, can install multiple lower molds. The electric drive roller 201 drives the annular moving belt 202 to move. The annular moving belt 202 and the lower mold base 3 move synchronously. The lower mold base 3 moves to the bottom of the upper mold lifting pressure frame 102. The pressure telescopic cylinder 104 extends to support the upper mold lifting pressure frame 102 to move downward. The lower mold base 3 and the middle lifting frame 2 move downward synchronously and compress the lower support spring 203. The bottom of the lower mold base 3 and the top of the middle support platform 105 are in contact and the downward movement stops. The middle support platform 105 enhances the support force on the lower mold base 3. The upper mold lifting pressure frame 102 presses down on the lower mold base 3 and the raw material on top of the lower mold base 3. The flame-retardant chloroprene rubber is pressurized and produced. The flame-retardant chloroprene rubber is deformed into the shape of the upper and lower molds. The annular moving belt 202 moves the lower mold base 3 to the outside of the upper mold lifting pressure frame 102 for the placement of the flame-retardant chloroprene rubber raw material and the removal of the finished product. This eliminates the need for personnel to place flame-retardant neoprene rubber raw materials and retrieve finished products below the upper mold lifting and pressing frame 102, making the work safer and preventing injuries caused by personnel's arms not being retracted in time when the upper mold lifting and pressing frame 102 moves downward. After pressurization, the upper mold lifting and pressing frame 102 moves upward and separates from the lower mold seat 3. The lower support spring 203 supports the middle lifting frame 2 and the lower mold seat 3 to move upward. The lower mold seat 3 separates from the middle support platform 105. The annular moving belt 202 drives the suspended lower mold seat 3 to move. The movement resistance of the lower mold seat 3 is reduced, and the lower mold seat 3 does not increase the movement resistance of the annular moving belt 202, avoiding the situation where the lower mold seat 3 has high movement resistance when moving along the top of the middle support platform 105. The middle support platform 105 supports the lower mold seat 3 during pressurization, and the middle lifting frame 2 moves downward simultaneously. The middle lifting frame 2 and the electric drive roller 201 do not bear pressure, and the electric drive roller 201 is also protected from damage to related bearing components caused by bearing pressure.

[0037] The top array of the annular moving belt 202 is equipped with multiple lower mold seats 3. While one lower mold seat 3 is being pressurized, personnel can place raw materials or remove finished products from another lower mold seat 3. Compared with a single lower mold seat 3, this reduces processing gaps and waiting time, shortens the time for placing raw materials or removing finished products, and improves processing efficiency.
