[0002] At present, general rubber hoses are mostly produced by extrusion, while rubber hoses with higher requirements and irregular shapes are mostly produced by molds. Currently, the molds used for producing rubber hoses by molds consist of an upper mold and a lower mold. The production steps are roughly as follows: molten rubber raw material is injected into the mold through the feed pipe, and after the rubber raw material cools, it forms a rubber hose.
[0003] In the existing technology, the lower mold is in a fixed state under normal conditions, while the upper mold is fixed on a movable installation platform. However, the upper and lower molds are both designed as one piece, which makes it cumbersome to replace the mold. In addition, in the existing technology, rubber hoses mostly rely on natural heat dissipation to achieve the cooling effect during production, which reduces the cooling efficiency.
[0004] To address these issues, we provide an assembly mold for rubber hose production. Utility Model Content

The upper and lower molds can be quickly assembled and disassembled through the cooperation of the outer shell, the abutment groove and the bolts. The upper and lower molds are cooled by the flow of water through the delivery pump, thereby improving the cooling efficiency. This solves the problems of existing molds where the upper and lower molds are designed as one piece, which makes the mold replacement operation more complicated. In addition, in the existing technology, rubber hoses mostly rely on natural heat dissipation to achieve the cooling effect, which reduces the cooling efficiency.

Detailed Implementation
[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model is an assembly mold for producing rubber tubes, including a mold body 1. The mold body 1 includes an upper mold 103 and a lower mold 104 below the upper mold 103. The upper mold 103 and the lower mold 104 are symmetrically provided with outer shells 102. The upper mold 103 and the lower mold 104 are respectively clearance-fitted with the corresponding outer shells 102. The left and right side walls of the upper mold 103 and the lower mold 104 are provided with abutment grooves 106. At the location of the abutment groove 106, a bolt 102a is threadedly connected to the side wall of the outer shell 102. The inner end of the bolt 102a is semi-circular. By using the inner end of the bolt 102a to enter the abutment groove 106 and abut against the corresponding upper mold 103 and lower mold 104, the upper mold 103 and the lower mold 104 can be fixed to the corresponding outer shell 102.
[0030] Specifically, an electric push rod 101 is fixedly installed on the upper wall of the upper outer shell 102. The upper mold 103 can be made to contact or separate from the lower mold 104 by working the electric push rod 101. An L-shaped mounting plate 101a is fixedly installed at the upper end of the electric push rod 101. The upper outer shell 102 is slidably connected to the mounting plate 101a. The rear side of the mounting plate 101a is fixedly connected to the lower outer shell 102.
[0031] The upper mold 103 and the lower mold 104 are provided with bosses 102c along the edge corresponding to the side wall of the outer shell 102. A sealing gasket 105 is provided between the upper mold 103 and the lower mold 104 and the corresponding boss 102c to prevent leakage of cooling water. The sealing gasket 105 can be fixed to the upper wall of the corresponding boss 102c. The inner side of the boss 102c is provided with baffles 102b that are fixed to the outer shell 102 and make the water move in a serpentine manner from left to right. The baffles 102b can make the cooling water flow in a serpentine manner, thereby improving the heat dissipation effect on the upper mold 103 and the lower mold 104.
[0032] The inclined surface in the abutment groove 106 on the lower mold 104 gradually rises from the outside to the inside, and the inclined surface in the abutment groove 106 on the upper mold 103 gradually descends from the outside to the inside. With the above arrangement, when the two bolts 102a on the lower side are tightened, the two bolts 102a on the lower side will exert a downward force on the lower mold 104 to squeeze the sealing gasket 105 on the lower side. Similarly, when the two bolts 102a on the upper side are tightened, the two bolts 102a on the upper side will exert an upward force on the upper mold 103 to squeeze the sealing gasket 105 on the upper side to ensure sealing. The left wall of the upper mold 103 is fixed with a feed pipe 103a. The inside of the feed pipe 103a is connected to the inside of the mold cavity in the upper mold 103. By injecting molten rubber raw material into the feed pipe 103a, the rubber raw material will enter the mold cavities of the upper mold 103 and the lower mold 104 to realize the production of rubber tubes.
[0033] Furthermore, a limit switch is provided at the end of the stroke of the electric push rod 101 to ensure that the upper mold 103 and the lower mold 104 are completely closed or separated.
[0034] The operation process of this embodiment is as follows: When installing the upper mold 103 and the lower mold 104, first place the lower mold 104 inside the outer shell 102 located on the lower side, then tighten the two bolts 102a located on the lower side, then place the upper mold 103 on the upper surface of the lower mold 104, so that the electric push rod 101 extends and drives the outer shell 102 located on the upper side to descend until the outer shell 102 located on the upper side is fitted onto the outside of the upper mold 103, and tighten the two bolts 102a located on the upper side to complete the installation of the upper mold 103 and the lower mold 104;
[0035] During disassembly, extend the electric push rod 101 until the upper mold 103 contacts the lower mold 104. At this time, loosen the two bolts 102a on the upper side to separate the upper mold 103 from the outer shell 102 on the upper side. Then, retract the electric push rod 101 to move the outer side on the upper side upward and remove the upper mold 103. Then loosen the two bolts 102a on the lower side to remove the lower mold 104.
[0036] Example 2
[0037] Please see Figure 1 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a cooling mechanism 2 is provided on the outside of the mold body 1. The cooling mechanism 2 includes a water tank 206 located below the outer shell 102. A water pump 205 is provided on the left side of the water tank 206. A connecting pipe 205a and a left three-way pipe 207 are respectively fixed to the inlet and outlet ends of the water pump 205. The connecting pipe 205a communicates with the inside of the water tank 206. The right end of the connecting pipe 205a is fixedly connected to the lower side of the water tank 206. The other two ends of the left three-way pipe 207 are respectively fixedly connected to the left wall of the outer shell 102. Next, a right tee pipe 201 is fixedly installed on the right wall of the water tank 206. The other two ends of the right tee pipe 201 are fixedly connected to the right wall of the outer shell 102 respectively. The right tee pipe 201 communicates with the inside of the water tank 206. At the same time, the inside of the right tee pipe 201 communicates with the inside of the corresponding outer shell 102. With the above configuration, the cooling water in the water tank 206 is transported by the water pump 205, so that the cooling water circulates between the water tank 206, the connecting pipe 205a, the left tee pipe 207, the outer shell 102 and the right tee pipe 201 under the action of the water pump 205 to remove the heat generated during the production of the rubber hose.
[0038] Specifically, rectangular slots 206c are provided on the upper ends of both the front and rear sides of the water tank 206. When the airflow generated by the fan 204 acts on the cooling water inside the water tank 206, the airflow will pass through the rectangular slots 206c and be discharged to dissipate heat from the cooling water. A transparent window 206b is fixed on the side wall of the water tank 206 for viewing the liquid level inside the water tank 206.
[0039] A connecting plate 202 is fixedly installed on the upper wall of the water tank 206. A connecting rod 202a is fixedly installed at each of the four corners of the upper wall of the connecting plate 202. The upper end of the connecting rod 202a is fixedly connected to the outer shell 102 located on the lower side.
[0040] The upper wall of the connecting plate 202 has a perforation 202b. Above the perforation 202b, there is a fan 204 fixed to the connecting plate 202. When the fan 204 works, it causes airflow to enter the water tank 206 to dissipate heat from the cooling water in the water tank 206. The upper wall of the fan 204 is fixed with a dust filter 204a to prevent large dust particles from entering the water tank 206 with the airflow.
[0041] Screw sleeves 206a are fixed at the four corners of the lower wall of the water tank 206. The screw rods 203 are connected to the internal threads of the screw sleeves 206a. The lower end of the screw rods 203 is fixed with a base plate 203a. With the above configuration, the corresponding screw rods 203 are rotated by rotating the base plate 203a. With the cooperation of the screw sleeves 206a, all four base plates 203a are in contact with the installation platform, so that the cooling mechanism 2 can be stably placed on the installation platform.
[0042] The operation process of this embodiment is as follows: When the rubber tube needs to be cooled, the water pump 205 is turned on. Under the operation of the water pump 205, the cooling water passes through the connecting pipe 205a and the left three-way pipe 207 in sequence and enters the space between the upper mold 103 and the outer shell 102 and the lower mold 104 and the outer shell 102 respectively. Then, under the action of the corresponding baffle 102b, the cooling water moves in a serpentine motion to absorb the heat of the upper mold 103 and the lower mold 104 to achieve the cooling effect. After that, the cooling water will pass through the right three-way pipe 201 and re-enter the water tank 206 to achieve the circulation of cooling water for cooling.
[0043] During the above process, the fan 204 is activated to generate airflow. The airflow passes through the perforation 202b and moves vertically downwards, acting on the cooling water inside the water tank 206. At this time, the airflow carries the heat in the cooling water and diffuses to the surroundings and moves upwards. It then passes through the rectangular groove 206c and is discharged to the outside to achieve heat dissipation of the cooling water.
[0044] It should be noted that the process of producing rubber tubes using molds is existing technology and will not be elaborated here. Meanwhile, the electric push rod 101, water pump 205 and fan 204 are all electrically connected to the controller via conductive wires, and the controller is electrically connected to an external power supply via conductive wires. The electric push rod 101, water pump 205, fan 204 and controller are all existing technologies, and their models are not limited here.
