Description

Technical Field

[0001] This utility model relates to the field of compression molding machine technology, specifically to a rubber product compression molding machine that facilitates material unloading. Background Technology

[0002] The rubber product molding machine with easy material ejection is a key piece of equipment in the rubber production industry. It is dedicated to efficiently and accurately completing the molding process of rubber products and solving the material ejection problems of traditional equipment. Its main structure is robust, constructed of high-strength steel, ensuring operational stability and long-term durability. Crucially, it is equipped with an innovative material ejection device, typically including a mechanical ejection structure and pneumatic auxiliary components. After the product is molded, the material ejection device responds quickly, mechanically driving the finished product out of the mold, while the pneumatic components provide simultaneous assistance, precisely controlling the force and angle to ensure that the rubber product can be completely and efficiently ejected from the mold. This significantly improves production efficiency, reduces labor costs, and minimizes product damage caused by improper material ejection.

[0003] After the existing stamping die completes the stamping process, the product remains in the lower die. It mostly relies on manual removal of the product from the die. However, manual removal requires a lot of time and effort, is inefficient, and is prone to edge damage and surface scratches, which leads to inconvenience in unloading the product. To address this, we propose a rubber product compression molding machine that facilitates unloading. Utility Model Content

[0006] The demolding mechanism includes a support plate, the lower surface of which is fixedly connected to the upper surface of the collecting mechanism. A mounting base is fixedly connected to the upper surface of the support plate, and a drive telescopic rod is mounted on the upper surface of the mounting base. A connecting plate is fixedly connected to the telescopic end of the drive telescopic rod, a transmission rod is fixedly connected to the lower end of the connecting plate, and a fixing block is fixedly connected to the upper end of the connecting plate.

[0008] As a further preferred embodiment of this technical solution, the support plate has a sliding groove inside, and a discharge port for discharging materials is also provided through the middle of the support plate. A pipe is fixedly connected to the inner cavity of the discharge port. The right end of the air storage cylinder is fixedly connected to the left side wall of the pipe. A lower mold is provided at the bottom of the inner cavity of the pipe. The lower mold is a tubular through-type mold. The lower surface of the lower mold is at the same level as the lower surface of the pipe. The lower surface of the lower mold and the bottom end of the pipe both penetrate the support plate and extend into the limiting groove.

[0009] As a further preferred embodiment of this technical solution, a reinforcing plate for supporting material forming is fixedly connected to one side of the transmission rod. The reinforcing plate slides in the groove, and a gap is reserved between the transmission rod and the reinforcing plate. The lower surface of the reinforcing plate is in movable contact with the surface of the feeding port, and the upper surface of the reinforcing plate is in movable contact with the lower surface of the lower mold.

[0010] As a further preferred embodiment of this technical solution, the collection mechanism includes a fixing rod, the bottom end of which is fixedly connected to the upper surface of the base plate, a placement plate is fixedly sleeved on the surface of the fixing rod, a collection box is placed on the surface of the placement plate, and the top end of the fixing rod is fixedly connected to the lower surface of the support plate.

[0013] This utility model provides a rubber product compression molding machine that facilitates material unloading, and has the following beneficial effects:

[0014] This invention involves placing the material in the lower mold, and then using the telescopic end of an electric telescopic rod to press the upper mold down into the lower mold, forming the product. Adjusting the telescopic end of the electric telescopic rod then moves the upper mold away from the lower mold. A rubber ring is positioned above the tube body to seal the top of the tube. Adjusting the telescopic end of the drive rod moves a reinforcing plate to allow the material to exit through the discharge port. The formed product falls from the discharge port into a collection box. Simultaneously, adjusting the telescopic end of the drive rod moves a piston, releasing gas from the gas storage cylinder into the lower mold. The increased gas in the lower mold impacts the formed product, accelerating the product ejection speed. This method saves time and effort while ensuring the quality of the formed product and is convenient to use. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 and Figure 2 A rubber product molding machine for easy material removal includes a base plate 1. A collecting mechanism 3 is provided on the upper surface of the base plate 1. A demolding mechanism 2 is provided on the upper surface of the collecting mechanism 3. A telescopic mechanism 4 is provided on the surface of the demolding mechanism 2. The demolding mechanism 2 includes a support plate 21 for bearing the weight of the object above. The lower surface of the support plate 21 is fixedly connected to the upper surface of the collecting mechanism 3. A mounting base 22 is fixedly connected to the upper surface of the support plate 21. A drive telescopic rod 23 is mounted on the upper surface of the mounting base 22. A connecting plate 24 is fixedly connected to the telescopic end of the drive telescopic rod 23. A transmission rod 25 is fixedly connected to the lower end of the connecting plate 24. A fixing block 27 is fixedly connected to the upper end of the connecting plate 24. By adjusting the telescopic end of the drive telescopic rod 23, the connecting plate 24 can be moved, thereby moving the transmission rod 25 and the fixing block 27.

[0024] It should be noted that the drive telescopic rod 23 is an electrically driven telescopic rod.

[0025] Please see Figure 2 , Figure 3 and Figure 6 The surface of the support plate 21 is provided with a limiting groove 26 for limiting the transmission rod 25. The transmission rod 25 is slidably connected to the surface of the limiting groove 26. The right end of the fixing block 27 is fixedly connected to a push rod 28, and the right end of the push rod 28 is fixedly connected to a piston 29. The surface of the piston 29 is slidably connected to an air storage cylinder 201. By driving the extension end of the telescopic rod 23 to move the push rod 28, the gas in the air storage cylinder 201 can be discharged into the pipe body 202 to assist the product in demolding.

[0026] Please see Figure 2 and Figure 3 The support plate 21 has a sliding groove 204 inside, and a discharge port for discharging materials is also opened through the middle of the support plate 21. The inner cavity of the discharge port is fixedly connected to a pipe body 202. The right end of the air storage cylinder 201 is fixedly connected to the left side wall of the pipe body 202. The inner cavity of the pipe body 202 is provided with a lower mold 203. The lower mold 203 is a tubular through-type mold. The bottom of the lower mold 203 and the bottom of the pipe body 202 are located on the same horizontal plane. This horizontal plane is the plane where the top wall plate of the limiting groove 26 is located, and both are aligned with the horizontal plane of the pipe body 202. The upper surface of the reinforcing plate 205 is in contact with the surface of the transmission rod 25, and the reinforcing plate 205 for supporting material forming is fixedly connected to the surface of the transmission rod 25. The transmission rod 25 is located outside the discharge port, and the reinforcing plate 205 slides in the slide groove 204. The lower surface of the reinforcing plate 205 is in movable contact with the surface of the discharge port. A crossbar is fixedly connected to the side of one end of the reinforcing plate 205. The end of the crossbar away from the reinforcing plate 205 is fixedly connected to the transmission rod 25. The material falls into the discharge port through the gap between the reinforcing plate 205 and the transmission rod 25.

[0027] In practice, after the upper mold 47 presses down to form the material in the lower mold 203, the material is discharged from the discharge port by adjusting the extension end of the drive telescopic rod 23 to move the reinforcing plate 205 and the product falls into the collection box 33 below.

[0028] Please see Figure 1 and Figure 4 The collection mechanism 3 includes a fixed rod 31, the bottom end of which is fixedly connected to the upper surface of the base plate 1. A placement plate 32 is fixedly sleeved on the surface of the fixed rod 31, and a collection box 33 is placed on the surface of the placement plate 32. The top end of the fixed rod 31 is fixedly connected to the lower surface of the support plate 21. The collection box 33 is used to collect the product. After production is completed, the collection box 33 is removed and the product is further processed.

[0029] Please see Figure 1 and Figure 5 The telescopic mechanism 4 includes a fixed frame 41, the bottom end of which is fixedly connected to the upper surface of the support plate 21, and a top plate 42 is fixedly connected to the top end of the fixed frame 41. A mounting frame 43 is provided on the upper surface of the top plate 42, and an electric telescopic rod 44 is mounted on the surface of the mounting frame 43. The surface of the electric telescopic rod 44 is fixedly inserted into the middle of the top plate 42. The electric telescopic rod 44 is fixed by using the mounting frame 43 and the top plate 42, which facilitates its later use.

[0030] Please see Figure 1 , Figure 5 and Figure 6 A sealing block 45 is fixedly connected to the telescopic end of the electric telescopic rod 44. A rubber ring 46 is fixedly connected to the edge of the sealing block 45. An upper mold 47 is provided on the lower surface of the sealing block 45. The surface of the rubber ring 46 contacts the inner surface of the tube body 202. The upper mold 47 is pressed down by the telescopic end of the electric telescopic rod 44 to form the material. The sealing performance of the tube body 202 is enhanced when the sealing block 45 is inside the tube body 202 by the squeezing of the rubber ring 46.

[0031] The working principle of this rubber product molding machine, which facilitates material removal, will be explained in detail below.

[0032] like Figure 1 - Figure 6As shown, by placing the material in the lower mold 203, the upper mold 47 is pressed down into the lower mold 203 by the telescopic end of the electric telescopic rod 44, allowing the product to be formed. Then, the telescopic end of the upper mold 47 is adjusted to move the upper mold 47 away from the lower mold 203. The rubber ring 46 is located above the tube body 202, sealing the upper part of the tube body 202. By adjusting the telescopic end of the drive telescopic rod 23, the connecting plate 24 is moved, thereby moving the reinforcing plate 205 and the piston 29. This allows the material to leak out of the discharge port while simultaneously venting the gas in the air storage cylinder 201 into the lower mold 203. The increased gas in the lower mold 203 impacts the formed product, accelerating the unloading speed of the formed product. The product falls into the collection box 33 through the discharge port. When the telescopic end of the drive telescopic rod 23 is adjusted to close the discharge port with the reinforcing plate 205, the piston 29 moves, causing gas to enter the air storage cylinder 201, preparing for the next unloading.
