[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-4 As shown, the utility model provides a gun-type valve stem mold structure, including a mold mechanism 1, and a heating mechanism 2 is arranged on one side of the mold mechanism 1;

[0027] The heating mechanism 2 includes four manual valves 201, a water tank 207 and a water hole 209. The four manual valves 201 are divided into two groups. A three-way hose 202 is installed between the water inlet ends of one group of manual valves 201 and between the water outlet ends of the other group of manual valves 201. A first hose 203 is installed at the water inlet end of one of the three-way hoses 202 and the water outlet end of the other three-way hose 202. An iron pipe 205 is installed at the water inlet end of one of the first hoses 203. An electromagnetic coil 206 is movably sleeved on the outer wall of the iron pipe 205. A heat-resistant bracket 204 is installed on the outer wall of the iron pipe 205. A second hose 210 is installed at the water inlet end and the water outlet end of the water tank 207. A water pump 208 is installed on the top of the water tank 207, and the electromagnetic coil 206 is located between the two sides of the inner wall of the heat-resistant bracket 204, and both ends of the electromagnetic coil 206 are fixed through the front surface of the inner wall of the heat-resistant bracket 204, the water outlet end of one second hose 210 is installed with the water inlet end of the iron pipe 205, the water inlet end of another second hose 210 is installed with the water outlet end of the water pump 208, the water outlet end of another first hose 203 is installed with the water inlet end of the water pump 208, and the water inlet end of another group of manual valves 201 is respectively installed with the water outlet ends of the two water holes 209, and the water outlet ends of one group of manual valves 201 are respectively installed with the water inlet ends of the two water holes 209.

[0028] The effect achieved by the entire embodiment 1 is that when it is necessary to accelerate the curing time of the foam glue, the water pump 208 and the electromagnetic coil 206 are first connected to the external controller (PLC controller), and then the controller is connected to the power supply, and then the four manual valves 201 are manually unscrewed, and then the water pump 208 and the electromagnetic coil 206 are started at the same time by the external controller. When the water pump 208 is started, the water pump 208 started at this time will directly allow the water inlet end of one of the second hoses 210 to obtain suction under the effect of the connection relationship between the various components of the heating mechanism 2. At this time, the water inlet end of one of the second hoses 210 that obtains suction will extract the water inside the water tank 207, and then the second hose 210 will transport the extracted water into the inside of the iron pipe 205. When the water reaches the inside of the iron pipe 205, the electromagnetic coil 206 that is started at this time will directly heat the water passing through the inside of the iron pipe 205, and then the heated water will be transported to the inside of the first hose 203 connected thereto, and then transported to the inside of the corresponding three-way hose 202. When the hot water reaches the three-way hose 2 02, at this time, under the action of the three-way hose 202, the water entering the three-way hose 202 is directly diverted and transported to the inside of the two manual valves 201 connected thereto, and then transported to the inside of the two water holes 209 connected thereto. When hot water is transported to the inside of the two water holes 209, the hot water flowing in the two water holes 209 will directly transfer heat to the upper mold 101 and the lower mold 102, that is, the heat of the heat transfer is used to accelerate the curing speed of the foam glue, thereby reducing the curing time of the foam glue. Then, the water after heat transfer will be directly transported to the inside of the other two manual valves 201, and then collected into the inside of the three-way hose 202 connected thereto, and then directly transported to the inside of the first hose 203 connected thereto, and then through the cooperation of the water pump 208 and the corresponding second hose 210, the water transported by the first hose 203 can be transported back to the inside of the water tank 207, that is, the water circulation heating operation is achieved, and this reciprocating process can accelerate the production time of the gun-type valve stem mold to produce the foam glue end cap and improve the production efficiency.

[0029] Embodiment 2, as Figure 1 and Figure 4-6 As shown, the mold mechanism 1 includes an upper mold 101, a lower mold 102 is arranged on the lower side of the upper mold 101, a mounting groove 103 is opened on the top of the upper mold 101, a sealing cover 104 is installed at the notch of the mounting groove 103 by a hand-tightening bolt, a circular ring block 105 is installed at the top feed port of the sealing cover 104, a gun-type valve stem 106 is movably penetrated through the outer wall of the circular ring block 105, one end of the gun-type valve stem 106 is threadedly connected to the inner wall of the circular ring block 105, and two water holes 209 are respectively opened on one side of the upper mold 101 and one side of the lower mold 102.

[0030] The effect achieved by the entire embodiment 2 is that when it is necessary to use a gun-type valve stem mold to produce a foam rubber end cap, the upper mold 101 and the lower mold 102 are firstly installed together and placed on a workbench, and then the sealing cover 104 is installed at the notch of the installation groove 103 by means of hand-tightening bolts, and then the top feed end of the circular ring block 105 is connected to the outlet end of the delivery pipe of the foam rubber delivery device, and then the gun-type valve stem 106 is rotated to adjust the speed of the foam rubber passing through the inside of the circular ring block 105, and then the foam rubber is directly injected into the inside of the circular ring block 105. Into the foam glue, and then the foam glue entering the inside of the circular ring block 105 will directly enter the inside of the installation groove 103, and finally be divided and injected into the mold space composed of the upper mold 101 and the lower mold 102. When the foam glue inside this space is filled, directly rotate the gun-type valve stem 106 to stop the injection of the foam glue, and then wait for the foam glue between the inside of the upper mold 101 and the lower mold 102 to complete solidification, then the upper mold 101 and the lower mold 102 can be disassembled to obtain the foam glue end cap, and then continue to produce the foam glue end cap according to the above-mentioned operating steps.

[0031] Working principle: When it is necessary to use a gun-type valve stem mold to produce foam rubber end caps, the upper mold 101 and the lower mold 102 are first installed together and placed on the workbench, and then the water pump 208 and the electromagnetic coil 206 are connected to the external controller (PLC controller), and then the controller is connected to the power supply, and then the four manual valves 201 are manually unscrewed, and then the water tank 207 and the heat-resistant bracket 204 are placed on the workbench together, and the heat-resistant bracket 204 is fixed with screws, and then the water pump 208 and the electromagnetic coil 206 are started at the same time by the external controller. When the water pump 208 is started, the water pump 208 started at this time will directly allow one of the second hoses 210 to flow under the action of the connection relationship between the components of the heating mechanism 2. The water inlet end obtains suction, and the water inlet end of one of the second hoses 210 that obtains suction will pump out the water inside the water tank 207, and then the second hose 210 will transport the pumped water into the inside of the iron pipe 205. When the water reaches the inside of the iron pipe 205, the electromagnetic coil 206 that is activated at this time will directly heat the water passing through the inside of the iron pipe 205, and then the heated water will be transported to the inside of the first hose 203 connected thereto, and then transported to the inside of the corresponding three-way hose 202. When the hot water reaches the inside of the three-way hose 202, under the action of the three-way hose 202, the water entering the three-way hose 202 is directly diverted and transported to the inside of the two manual valves 201 connected thereto, and then transported to the two connected thereto. The hot water is then directly transported to the inside of the other two manual valves 201, and then collected into the inside of the three-way hose 202 connected thereto, and then directly transported to the inside of the first hose 203 connected thereto, and then through the cooperation of the water pump 208 and the corresponding second hose 210, the water transported by the first hose 203 can be transported back to the inside of the water tank 207, that is, the water circulation heating operation is achieved. When the upper mold 101 and the lower mold 102 are heated to a suitable temperature, the sealing cover 104 is installed at the notch of the mounting groove 103 by hand-tightening bolts, and then the top feeding end of the circular ring block 105 is connected to the outlet end of the delivery pipe of the foaming glue delivery equipment, and then the gun-type valve stem 106 is rotated to adjust the The speed of the foam glue passing through the inside of the circular block 105 is controlled, and then the foam glue is directly injected into the inside of the circular block 105. Then, the foam glue entering the inside of the circular block 105 will directly enter the inside of the mounting groove 103, and then be divided and injected into the mold space composed of the upper mold 101 and the lower mold 102. When the foam glue in this space is full, the gun-type valve stem 106 is directly rotated to stop the injection of the foam glue. At this time, the foam glue between the upper mold 101 and the lower mold 102 will accelerate the curing speed of the foam glue through the heat transferred by the hot water flowing in the two water holes 209, thereby reducing the curing time of the foam glue and improving the production efficiency. Then, the foam glue between the inside of the upper mold 101 and the lower mold 102 is completed.The upper mold 101 and the lower mold 102 can be disassembled to obtain the foam rubber end cap, and then the foam rubber end cap can be produced according to the above operation steps;

[0032] The water outlet of the water tank 207 is located near the bottom of the outer wall of the water tank 207, and the water inlet of the water tank 207 is located near the top of the outer wall of the water tank 207. The three-way hose 202 is made of heat-resistant rubber material and can be bent and deformed. The size used is selected according to actual conditions.

[0033] The wiring diagram of the water pump 208 and the electromagnetic coil 206 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the water pump 208 and the electromagnetic coil 206 are not explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
