Description

Technical Field

[0001] This utility model relates to the field of rubber vulcanization molding technology, specifically a rubber vulcanization molding device. Background Technology

[0002] Rubber vulcanization molding is a process that uses vulcanizing agents and high temperatures to cause cross-linking reactions between rubber molecules, forming a three-dimensional network structure and improving the physical properties and chemical stability of rubber. The vulcanization molding process mainly includes mixing and vulcanization. Mixing involves mixing rubber with vulcanizing agents, accelerators and other compounding agents to form mixed rubber granules. Vulcanization involves placing the mixed rubber granules into upper and lower molding molds and vulcanizing them into basic shapes such as plates and strips under high temperature and high pressure.

[0003] Currently, most rubber vulcanization molding equipment operates the mixing and vulcanization processes separately. After the upper and lower molding dies complete the first vulcanization, the mixed rubber granules are manually fed into the cavity of the lower molding die. Then, the upper and lower molding dies are closed for a second rubber vulcanization. It is not easy to automatically feed the mixed rubber granules into the lower molding die during the vulcanization molding process, nor is it easy to combine the mixing and vulcanization processes together. This is not conducive to improving the overall efficiency of rubber vulcanization molding. Utility Model Content

[0004] The purpose of this invention is to provide a rubber vulcanization molding apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rubber vulcanization molding apparatus, comprising:

[0007] A frame, comprising a rectangular frame, on which two guide rails and two I-beams are fixed;

[0008] There are two lower forming molds, each of which is slidably connected to two guide rails;

[0009] The upper forming mold is positioned above the lower forming mold;

[0010] Multiple demolding components are arranged inside the lower and upper molding molds respectively, which enable the vulcanized rubber block to be demolded.

[0011] Two cylinders are fixed to a rectangular frame, and the output end of the cylinder is fixed to the upper forming mold.

[0012] There are two mixing components, each fixed between two C-shaped beams. Each mixing component includes a mixing tank, with a shaft rotatably connected inside the mixing tank. Multiple stirring blades are fixed to the outside of the shaft, and a motor capable of driving the shaft to rotate is fixed on the mixing tank.

[0013] Furthermore, the output end of the second motor and the top of the shaft are both fixed with synchronous pulleys, and a synchronous belt is used to drive the transmission between the two synchronous pulleys.

[0014] Furthermore, the guide rail is rotatably connected to a lead screw, the bottom of the lower forming mold has two movable seats that are respectively screwed to the lead screw at the corresponding position, and one end of the rectangular frame has two motors that can drive the lead screw to rotate.

[0015] Furthermore, the demolding assembly includes an electric push rod, the output end of which is fixed with an L-shaped rod, and the bottom of which is fixed with a push block.

[0016] Furthermore, the lower forming mold and the upper forming mold are respectively embedded and fixed with the electric push rods at corresponding positions, and the lower forming mold and the upper forming mold are respectively slidably inserted with the push blocks at corresponding positions.

[0017] Furthermore, the bottom of the mixing tank is provided with multiple fan-shaped holes, and the bottom of the shaft is rotatably fitted with multiple fan-shaped blocks.

[0018] Furthermore, a one-way bearing is sleeved between the plurality of the sector blocks and the shaft, and the area of ​​the sector block is larger than the area of ​​the sector hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. A lower molding die is driven by a screw rotating on a guide rail. The screw rotates and drives the lower molding die to slide along the guide rail to the bottom of the mixing tank. The circumference of the mixing tank, along with multiple fan-shaped blocks, rotates and leaves the fan-shaped holes, so that the pre-mixed rubber granules inside the mixing tank automatically fall into the cavity of the lower molding die. Then, the screw rotates in the opposite direction, allowing the lower molding die to move directly below the upper molding die. This facilitates the closing of the upper and lower molding dies, eliminating the need for manual feeding of rubber granules into the mold cavity and improving the feeding efficiency of rubber vulcanization molding.

[0021] 2. Two lower molding dies are slidably arranged on the guide rails of the frame, and two mixing tanks are fixed between the two I-beams of the frame. Each mixing tank contains rubber compound granules. During the mold closing process of one lower molding die and the upper molding die, the other lower molding die can move to the bottom of the corresponding mixing tank to collect the rubber compound granules. This allows for the preparation of a spare lower molding die and rubber compound granules while the rubber is being vulcanized. So that when the lower molding die is removed from the upper molding die for demolding after the mold is closed and vulcanized, the spare lower molding die, carrying the rubber compound granules, moves to the bottom of the upper molding die for continuous mold closing. At the same time, the demolded lower molding die can still collect the rubber compound granules under the corresponding mixing tank for continued vulcanization. This combines the mixing and vulcanization processes, which helps to improve the overall efficiency of rubber vulcanization molding. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, please refer to Figure 1 - Figure 6 In this embodiment of the invention, a rubber vulcanization molding apparatus includes a frame 100, which includes a rectangular frame 110. Guide rails 120 are fixed on both sides of the rectangular frame 110. Two mutually fixed lower molding molds 200 are slidably connected between the two guide rails 120. Cylinders 500 are fixed on both sides of the rectangular frame 110. An upper molding mold 300 is fixed between the output ends of the two cylinders 500. The lower molding mold 200 and the upper molding mold 300... Each part is equipped with a demolding component 400. Both sides of the top of the rectangular frame 110 are fixed with a C-shaped beam 130. Two mixing components 600 are arranged between the two C-shaped beams 130. The mixing component 600 includes a mixing tank 610 fixed to the two C-shaped beams 130. A shaft 620 is rotatably connected inside the mixing tank 610. Multiple stirring blades 630 are fixed on the outside of the shaft 620. A motor 640 that can drive the shaft 620 to rotate is fixed on the mixing tank 610.

[0031] Specifically, by arranging an upper molding die 300 and two lower molding dies 200 on the frame 100, and fixing two mixing tanks 610 on the frame 100 for mixing rubber and vulcanizing agent, when one lower molding die 200 is closed with the upper molding die 300 for rubber vulcanization, the other lower molding die 200 can be moved to the bottom of a mixing tank 610 to fill with mixed rubber granules for later vulcanization. After the vulcanized lower molding die 200 leaves the upper molding die 300, the spare lower molding die 200, carrying mixed rubber granules, replaces the demolded lower molding die 200 and is closed with the upper molding die 300 for secondary vulcanization. The demolded lower molding die 200 can still be filled with mixed rubber granules again under the corresponding mixing tank 610 for vulcanization, achieving the effect of continuous vulcanization and mold closing and mixing and feeding. By combining the two processes of mixing and vulcanization, the overall efficiency of rubber vulcanization molding is further improved.

[0032] like Figure 1 and Figure 6As shown, in this embodiment, both the output end of the second motor 640 and the top of the shaft 620 are fixed with synchronous pulleys. A synchronous belt is connected between the two synchronous pulleys. When the output end of the second motor 640 rotates clockwise, it can drive the shaft 620 to rotate clockwise through the synchronous belt, thereby causing multiple stirring blades 630 on the outside of the shaft 620 to stir the rubber particles and vulcanizing agent, so as to mix the compounded rubber particles for later use.

[0033] In this embodiment, refer to Figure 1 The outer side of the synchronous pulley and the synchronous belt is fitted with a protective shell 641 that is fixed to both the motor 640 and the mixing tank 610, which helps to protect the synchronous pulley and the synchronous belt. The top of the mixing tank 610 is fixed with a connecting seat 612, one end of which is rotatably connected to the shaft 620, so that the shaft 620 can rotate stably inside the mixing tank 610.

[0034] like Figure 3 and Figure 6 As shown, in this embodiment, the bottom of the mixing tank 610 is provided with a plurality of fan-shaped holes 611 through it at equal angles in an annular shape. The bottom of the shaft 620 is rotatably sleeved with a plurality of fan-shaped blocks 650 arranged at equal angles in an annular shape. A one-way bearing 651 is sleeved between the plurality of fan-shaped blocks 650 and the shaft 620. The area of ​​the fan-shaped blocks 650 is larger than the area of ​​the fan-shaped holes 611.

[0035] In this embodiment, initially, multiple sector blocks 650 respectively block the bottom of the corresponding sector holes 611 to prevent the rubber compound particles in the mixing tank 610 from falling. After the lower molding die 200 moves below the mixing tank 610, the motor 640 can drive the shaft 620 to rotate counterclockwise, causing the shaft 620 to drive the multiple sector blocks 650 to rotate away from the sector holes 611 through the one-way bearing 651, thereby allowing the rubber compound particles in the mixing tank 610 to move along the sector holes 611. 11 falls into the mold cavity of the lower forming mold 200. When the shaft 620 is pointing clockwise and carrying multiple stirring blades 630 to mix the rubber particles, the shaft 620 rotates on the one-way bearing 651. At this time, the one-way bearing 651 does not drive the multiple sector blocks 650 to rotate. The area of ​​the sector block 650 is set to be larger than the area of ​​the sector hole 611, so that the sector block 650 can completely block the sector hole 611, so that the bottom of the mixing tank 610 is in a closed state when mixing rubber particles and vulcanizing agent.

[0036] like Figure 4 and Figure 5As shown, in this embodiment, a lead screw 140 is rotatably connected inside the guide rail 120. Both ends of the lead screw 140 rotatably pass through the rectangular frame 110. Two movable seats are fixed at the bottom of the lower forming mold 200 and are respectively screwed to the lead screw 140 at the corresponding position. The movable seats are slidably connected to the guide rail 120. Two motors 150 that can drive the lead screw 140 to rotate are fixed at one end of the rectangular frame 110.

[0037] In this embodiment, the output end of motor 150 drives the lead screw 140 to rotate in the forward or reverse direction, which enables the moving seat to move the lower molding die 200 along the guide rail 120 to move left and right, so that the two lower molding dies 200 can respectively vulcanize and close the mold and receive the mixed rubber particles, so that vulcanization and mold closing and mixing and feeding in rubber vulcanization molding can be carried out simultaneously.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, support legs are fixed at the four corners of the bottom surface of the rectangular frame 110, which facilitates the installation of the rectangular frame 110 on the factory floor. A control cabinet 160 is fixed on one side of the rectangular frame 110. The control cabinet 160 is used to control the mechanical equipment used in the rubber vulcanization process. The control cabinet 160, the upper molding mold 300, and the lower molding mold 200 are all existing technology components. The specific electronic components inside the control cabinet 160 and the heating elements on the upper molding mold 300 and the lower molding mold 200 are not described in detail here.

[0039] Example 2: Based on Example 1, in order to facilitate the quick demolding of the vulcanized rubber block by the upper molding mold 300 and the lower molding mold 200.

[0040] like Figure 5 As shown, in this embodiment, the demolding assembly 400 includes an electric push rod 410, an L-shaped rod 420 fixed to the output end of the electric push rod 410, and a push block 430 fixed to the bottom of the L-shaped rod 420. The lower molding mold 200 and the upper molding mold 300 are respectively embedded and fixed to the electric push rod 410 at the corresponding positions. The lower molding mold 200 and the upper molding mold 300 are respectively slidably inserted into the push block 430 at the corresponding positions. The length of the push block 430 in the lower molding mold 200 is shorter than the length of the push block 430 in the upper molding mold 300. The length of the push block 430 is mainly determined by the thickness of the mold.

[0041] In this embodiment, during demolding, refer to Figure 2The output end of cylinder 500 extends, causing the upper molding mold 300 to move upward away from the lower molding mold 200. At the same time, the output end of electric push rod 410 on the upper molding mold 300 shortens, and L-shaped rod 420 moves downward with push block 430, making it easier for push block 430 to detach the vulcanized rubber block from the upper molding mold 300. Then, the lower molding mold 200 is moved away from the position directly below the upper molding mold 300 with the rubber block. Then, the output end of electric push rod 410 on the lower molding mold 200 shortens, and L-shaped rod 420 moves upward with push block 430, causing the vulcanized rubber block to detach from the lower molding mold 200, thus realizing the demolding of the vulcanized rubber block.
