Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing strip production, in particular to a forming mould for producing rubber sealing strips which can be cooled quickly. Background Art

[0002] Rubber sealing strips are a type of protective material widely used in various equipment and projects. They are mainly used for sealing, sound insulation, dustproofing, waterproofing and other functions. They are usually made of natural or synthetic rubber and have good flexibility, wear resistance, aging resistance and corrosion resistance. Rubber sealing strips are generally thermoformed by molds.

[0003] When using a mold to produce rubber sealing strips, since it is thermoforming, a cooling structure needs to be used to cool the mold after forming to accelerate the hardening of the sealing strip.

[0004] For example, in the prior art, Chinese patent publication number CN103737873A discloses a mold cooling water channel, wherein one end of a first water channel is located on the mold surface, and the other end is located inside the mold; each first water channel is parallel to each other; each first water channel is connected to two or more second water channels perpendicular to the first water channel; one end of the second water channel is connected to the first water channel, and the other end is located on the mold surface; the distance between the first water channel and the injection molded product is 8 to 12 mm, and the distance between each first water channel is 27 to 35 mm. By reducing the distance between the first water channels and increasing the arrangement density of the first water channels, the cooling area can be increased and the cooling speed can be improved. Reducing the distance between the first water channel and the injection molded product improves cooling efficiency and shortens the molding cycle.

[0005] Based on the above materials, it can be seen that the existing technology generally uses water flow to carry heat to achieve the purpose of cooling. However, in actual use, the water flow can only carry the heat of the mold, and the cooling effect on the product formed on the mold (i.e., the rubber sealing strip) is poor. Utility Model Content

[0006] The purpose of the utility model is to provide a molding die for producing rubber sealing strips that can be cooled quickly, so as to solve the problem of poor cooling effect on the molded product raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a forming mold for producing a rubber sealing strip capable of rapid cooling, comprising a horizontally placed mounting base plate, a lower mold fixedly mounted on the upper surface of the mounting base plate, and an upper mold corresponding to the lower mold disposed directly above the lower mold, and further comprising:

[0008] A forming cavity with a bent structure is provided in the middle of the upper surface of the lower mold, and positioning rods are fixedly installed at the four corners of the upper surface of the lower mold, and the positioning rods correspond to the hole structures provided at the four corners of the upper mold;

[0009] A water-cooling pipe is fixedly installed inside the lower mold, and the water-cooling pipe is configured as a copper serpentine structure. A heat-conducting plate is fitted above the water-cooling pipe. An atomizing spray mechanism is provided on the left side of the lower mold to accelerate the cooling speed.

[0010] The lower surface of the upper mold is provided with adsorption holes for adsorbing the rubber sealing strip after molding.

[0011] Preferably, the atomizing spray mechanism includes an atomizing nozzle fixedly mounted on the left upper surface of the lower mold, and the atomizing nozzle is communicated with the outlet position of the delivery pump.

[0012] Preferably, the delivery pump is fixedly installed on the left outer surface of the lower mold, and the delivery pump is communicated with the water tank through a delivery pipe fixedly installed at its inlet position.

[0013] Preferably, the water tank stores coolant inside, and a sliding disassembly and installation structure is formed between the water tank and the lower mold.

[0014] Preferably, a negative pressure box is fixedly installed in the middle position of the upper surface of the upper mold, and a connecting pipe is fixedly installed on the side of the negative pressure box, and the lower end of the connecting pipe is connected to the adsorption hole.

[0015] Preferably, a transversely arranged piston plate is installed inside the negative pressure box, and a return spring is fixedly installed between the upper surface of the piston plate and the inner wall of the negative pressure box.

[0016] Preferably, the piston plate is made of iron material, and the piston plate and an electromagnet fixedly installed at a middle position on the upper surface of the lower mold are magnetically attracted to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the molding die for producing the rubber sealing strip that can be quickly cooled adopts a new structural design, the specific contents of which are as follows:

[0018] 1. After the rubber sealing ring is formed, flow coolant into the water cooling pipe to cool the lower mold with the flowing coolant. At the same time, the heat conduction plate can accelerate the transfer of heat to the water cooling pipe and increase the cooling speed.

[0019] Furthermore, after the molding is completed, the delivery pump is turned on, and the coolant in the water tank is delivered to the atomizing nozzle through the delivery pipe. The coolant is atomized by the atomizing nozzle and then sprayed out, so that the atomized coolant contacts the molded rubber sealing strip, thereby achieving the purpose of quickly cooling the rubber sealing strip;

[0020] Furthermore, a sliding disassembly and installation structure is formed between the water tank and the lower mold, and the staff can add coolant to it by pulling out the water tank.

[0021] 2. When the upper mold and the lower mold are fitted together, the electromagnet is turned on and the piston plate is attracted by the magnetic effect of the electromagnet, causing the piston plate to move downward inside the negative pressure box, thereby exhausting the air in the piston box;

[0022] Furthermore, after the molding is completed, the upper mold moves upward. At this time, the power supply of the electromagnet is disconnected, so that the electromagnet loses its adsorption effect on the piston plate, and the piston plate is driven upward under the elastic action of the return spring, thereby forming a negative pressure inside the negative pressure box. The negative pressure effect causes the adsorption hole to adsorb the rubber sealing strip, thereby pulling out the rubber sealing strip to achieve demolding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 3 In order to achieve the purpose of cooling the mold, this embodiment provides the following technical solutions, which specifically disclose: a horizontally placed mounting base plate 1, a lower mold 2 is fixedly mounted on the upper surface of the mounting base plate 1, and an upper mold 3 corresponding to the lower mold 2 is arranged directly above the lower mold 2, a forming cavity 4 with a bent structure is opened in the middle position of the upper surface of the lower mold 2, and positioning rods 5 are fixedly mounted at the four corners of the upper surface of the lower mold 2, and the positioning rods 5 correspond to the hole structures opened at the four corners of the upper mold 3, a water-cooling pipe 6 is fixedly mounted inside the lower mold 2, and the water-cooling pipe 6 is arranged to be a copper serpentine bent structure, and a heat conducting plate 7 is fitted above the water-cooling pipe 6.

[0033] When using the device, the rubber raw material is first placed in the molding cavity 4 opened on the upper surface of the lower mold 2. Then the driving structure in the molding equipment drives the upper mold 3 to move downward to the position of closing the mold with the lower mold 2 (at this time the positioning rod 5 is inserted into the hole in the upper mold 3) to realize the heating molding operation. After the molding is completed, the flowing coolant is introduced into the water cooling pipe 6, and the flowing coolant is used to take away the heat to achieve the purpose of cooling. During this process, the heat conduction plate 7 accelerates the heat conduction and increases the cooling speed.

[0034] Example 2: Please refer to Figure 3-Figure 6 In order to solve the problem that the traditional device has poor cooling effect on the product after molding, this embodiment provides the following technical solutions, which specifically disclose: an atomizing spray mechanism for accelerating the cooling speed is provided on the left side of the lower mold 2, and the atomizing spray mechanism includes an atomizing nozzle 8 fixedly installed on the upper surface of the left side of the lower mold 2, and the atomizing nozzle 8 is connected to the outlet position of the delivery pump 10. The delivery pump 10 is fixedly installed on the outer surface of the left side of the lower mold 2, and the delivery pump 10 is connected to the water tank 9 through the delivery pipe 11 fixedly installed at its inlet position. The water tank 9 stores coolant, and a sliding disassembly and installation structure is formed between the water tank 9 and the lower mold 2.

[0035] After the molding is completed, the upper mold 3 moves upward to open the mold. At this time, the delivery pump 10 is turned on, and the delivery pump 10 is used to deliver the coolant in the water tank 9 to the atomizing nozzle 8 through the delivery pipe 11. The atomizing nozzle 8 is used to atomize the coolant and then spray it out, so that the water mist directly contacts the molded rubber sealing strip, thereby achieving the purpose of quickly cooling the rubber sealing strip. The staff regularly draws out the water tank 9 to add coolant inside.

[0036] Example 3: Please refer to Figure 6-Figure 7 In order to achieve the purpose of helping the product to be demolded, this embodiment provides the following technical solutions, which specifically disclose: an adsorption hole 12 for adsorbing the rubber sealing strip after molding is opened on the lower surface of the upper mold 3, a negative pressure box 13 is fixedly installed in the middle position of the upper surface of the upper mold 3, and a connecting pipe 14 is fixedly installed on the side of the negative pressure box 13, and the lower end of the connecting pipe 14 is connected to the adsorption hole 12, a transversely arranged piston plate 15 is installed inside the negative pressure box 13, and a return spring 16 is fixedly installed between the upper surface of the piston plate 15 and the inner wall of the negative pressure box 13, the piston plate 15 is set to an iron material, and the piston plate 15 and the electromagnet 17 fixedly installed in the middle position of the upper surface of the lower mold 2 are magnetically adsorbed to each other.

[0037] During the mold opening process, the power supply of the electromagnet 17 is disconnected (the electromagnet 17 is turned on during mold closing and the piston plate 15 in the negative pressure box 13 is adsorbed downward by the electromagnet 17). At this time, the electromagnet 17 disconnects the adsorption effect on the piston plate 15, and the piston plate 15 is driven upward by the elastic action of the reset spring 16, thereby forming a negative pressure inside the negative pressure box 13. The adsorption effect is used to generate suction in the adsorption hole 12 through the connecting pipe 14, and the molded rubber sealing strip is adsorbed under the action of the suction force, so that the molded sealing strip is pulled out of the molding cavity 4 by the upper mold 3 to achieve the purpose of demolding.
