Description
Technical Field

This leads to an imbalance of internal and external stresses during glass forming, and the coolant in the cooling channel is prone to continuous heating due to poor circulation. After long-term use, the cooling effect is significantly reduced. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are: the glass production mold equipped with a composite cooling structure:
[0019] 1. In this device, a protrusion is fixedly installed on the upper surface of the lower mold, and a groove that matches the protrusion is embedded in the lower surface of the upper mold. When the mold is closed, the protrusion and the groove are aligned and engaged to form a limiting structure, thereby limiting the horizontal displacement of the upper and lower molds after they are closed, avoiding mold offset during the mold closing process, and providing a basis for glass product forming.

After continuously spraying and cooling the upper mold in the upper chamber, the coolant flows back to the lower chamber through a connecting pipe on the lower surface of the upper chamber and a conveying hole on the upper surface of the lower chamber, forming a complete flow loop. The flowing coolant enhances the heat exchange efficiency between the coolant and the mold surface, thereby improving the overall efficiency of glass production. Attached Figure Description

[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] Please see Figures 1-6This utility model provides a technical solution: a glass production mold with a composite cooling structure, including a base 1, a lower box 2, a lower mold 3, a support column 4, an upper box 5, an upper mold 6, a top plate 7, an electric push rod 8, an injection pipe 9, a protrusion 10, a groove 11, an inlet pipe 12, an outlet pipe 13, a pump body 14, a connecting pipe 15, and a conveying hole 16.
[0031] A lower housing 2 is fixedly installed on the upper surface of the base 1. A lower mold 3 is embedded and fixedly installed on the upper surface of the lower housing 2. A support column 4 is fixedly installed on the upper surface of the base 1. An upper housing 5 is slidably installed on the outer surface of the support column 4. An upper mold 6 is embedded and fixedly installed on the lower surface of the upper housing 5. The upper mold 6 is aligned with the lower mold 3. The lower mold 3 and the upper mold 6 are engaged and spliced to form a mold cavity.
[0032] A top plate 7 is fixedly installed on the top of the support column 4. An electric push rod 8 is embedded and fixed on the surface of the top plate 7. The output end of the electric push rod 8 is fixedly connected to the upper surface of the upper box 5. An injection pipe 9 is fixedly installed on the surface of the top plate 7. The injection pipe 9 has a two-section structure. The lower section of the injection pipe 9 penetrates the upper box 5 and inserts into the inner wall of the upper mold 6. The upper section of the injection pipe 9 has a telescopic structure. The surfaces of the lower mold 3 and the upper mold 6 are provided with a locking and limiting structure. The locking and limiting structure achieves stable locking of the lower mold 3 and the upper mold 6 through the protrusion 10 and the groove 11. The locking and limiting structure includes the protrusion 10. The protrusion 10 is a hollow square frame structure. The protrusion 10 is fixedly installed on the upper surface of the lower mold 3. A groove 11 is provided above the protrusion 10. The groove 11 is embedded and fixed on the lower surface of the upper mold 6.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, when the electric push rod 8 is activated, the output end of the electric push rod 8 pushes the upper box 5 downwards and slides vertically downwards along the support column 4. As the upper box 5 descends, the hollow square frame structure protrusion 10 fixedly installed on the upper surface of the lower mold 3 will gradually engage with the groove 11 on the lower surface of the upper mold 6. At this time, the upper mold 6 and the lower mold 3 are joined together, and the horizontal limiting structure formed by the protrusion 10 and the groove 11 prevents horizontal displacement after the upper mold 6 and the lower mold 3 are joined together. At this time, the upper mold 6 and the lower mold 3 are joined together to form a complete mold cavity. After the mold is joined, molten glass raw material is injected into the mold cavity through the liquid injection pipe 9 for subsequent glass forming.
[0034] The lower housing 2 is hollow inside. The bottom of the lower mold 3, which is installed on the upper surface of the lower housing 2, is hollow and communicates with the interior of the lower housing 2. A liquid inlet pipe 12 is installed through one side surface of the lower housing 2, and a liquid outlet pipe 13 is installed through the other side surface of the lower housing 2. Valves are installed inside the liquid inlet pipe 12 and the liquid outlet pipe 13 respectively. A coolant delivery structure is provided on the surface of the base 1. The coolant delivery structure realizes the flow of coolant through the pump body 14 to increase the cooling efficiency. The coolant delivery structure includes the pump body 14, which is fixedly installed on the upper surface of the base 1. On the surface, one end of the pump body 14 is inserted into the lower housing 2 through a pipe, and the other end of the pump body 14 is inserted into the upper housing 5 through a pipe. The interior of the upper housing 5 is hollow. The top of the upper mold 6 installed on the lower surface of the upper housing 5 is hollow and communicates with the interior of the upper housing 5. The surface of the upper mold 6 is provided with a notch and communicates with the interior of the upper housing 5. A connecting pipe 15 is fixed through the lower surface of the upper housing 5. The connecting pipe 15 is a square tube structure that runs through the upper and lower parts. The lower end of the connecting pipe 15 engages with the conveying hole 16. The conveying hole 16 is located on the upper surface of the lower housing 2.
[0035] like Figure 4 , Figure 5 and Figure 6 As shown, during the cooling and molding process of the glass raw material, the valve of the inlet pipe 12 on one side of the lower housing 2 is opened, and coolant is injected into the lower housing 2 through the inlet pipe 12 until the coolant surface covers the bottom hollow area of the lower mold 3, ensuring that the lower mold 3 is in full contact with the coolant. The valve of the inlet pipe 12 is then closed. The pump body 14 on the upper surface of the base 1 is started. The pump body 14 draws coolant from the lower housing 2 through one end pipe and delivers the coolant to the upper housing 5 through the other end pipe. The coolant inside the lower housing 2 soaks the area of the lower mold 3 in contact with the cavity through the hollow area at the bottom of the lower mold 3, continuously absorbing the heat generated by the molding of the glass raw material, thus achieving uniform cooling of the lower mold 3. The coolant inside the upper housing 5 sprays directly onto the area of the upper mold 6 in contact with the cavity through the hollow area at the top and the notch on the surface of the upper mold 6. After the coolant fully contacts the surface of the upper mold 6, it carries away the heat, achieving efficient cooling of the upper mold 6 and avoiding excessive local temperature differences in the mold. The coolant sprayed and cooled by the upper mold 6 flows out through the connecting pipe 15 on the lower surface of the upper box 5. Since the lower end of the connecting pipe 15 is engaged with the conveying hole 16 on the upper surface of the lower box 2, the coolant can flow back into the lower box 2 through the connecting pipe 15 and the conveying hole 16, forming a coolant circulation loop, which shortens the glass forming time. After the glass is formed, the pump body 14 is turned off and the valve of the outlet pipe 13 on the other side of the lower box 2 is opened to discharge the coolant inside the lower box 2 and the upper box 5 through the outlet pipe 13. After the coolant is completely discharged, the valve of the outlet pipe 13 is closed and the electric push rod 8 is started. The electric push rod 8 drives the upper box 5 to slide upward, and the upper mold 6 and the lower mold 3 separate, so that the formed glass product can be removed.
[0036] Working principle: When using this glass production mold with a composite cooling structure, the electric push rod 8 is turned on, and the electric push rod 8 pushes the upper box 5 down along the support column 4. The protrusion 10 on the lower mold 3 engages with the groove 11 of the upper mold 6, and the lower mold 3 and the upper mold 6 are spliced to form a mold cavity. Molten glass raw material is injected into the cavity through the liquid injection pipe 9, and coolant is injected into the lower box 2. The pump body 14 on the base 1 is started to pump the coolant in the lower box 2 to the upper box 5. The lower mold 3 is cooled by being immersed in the coolant through the bottom hollow, and the upper mold 6 is cooled by being sprayed with coolant through the top hollow and the surface notch. The coolant flows back through the connecting pipe 15 of the upper box 5 and the conveying hole 16 of the lower box 2 to form a circulation. After the glass is formed, the pump body 14 is turned off, the liquid outlet pipe 13 is opened to drain the liquid, and the electric push rod 8 drives the upper box 5 to move upward, separating the upper mold 6 and the lower mold 3, so that the glass product can be taken out, which increases the overall practicality.
