Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a cooling structure for a multi-cavity thermoforming mold for aviation cups. Background Technology

[0002] The cooling structure of the multi-cavity thermoforming mold for aviation cups is the core functional component of the multi-cavity thermoforming mold for aviation cups. It is used to solve the problem of efficient and uniform cooling of multi-cavity molds in the thermoforming process of aviation cups. By optimizing the design of the cooling channel layout and selecting suitable cooling media (such as cooling water and cooling air), it achieves uniform cooling of each cavity and quickly removes the heat during product molding, taking into account the characteristics of synchronous production of multi-cavity molds.

[0003] The existing technology has the following drawbacks: the current mainstream cooling methods used in the industry are mostly single-mold water cooling or segmented cooling designs. Traditional molds usually only have cooling water channels for the lower mold, while the upper mold relies on natural heat dissipation or delayed water cooling. This asynchronous cooling mode is difficult to match the stringent requirements of temperature uniformity for multi-cavity molds. Especially in the thin-walled molding process of aviation cups, the temperature difference between the upper and lower molds can easily lead to defects such as warping and uneven wall thickness, which restricts the improvement of product quality. Therefore, a cooling structure for a multi-cavity thermoforming mold for aviation cups is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a cooling structure for a multi-cavity thermoforming mold for aviation cups, aiming to improve the problem of product quality being affected by asynchronous cooling of the upper and lower molds in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling structure for a multi-cavity thermoforming mold for an aviation cup, comprising a worktable, a support frame fixedly connected to the top of the worktable, a fixed plate fixedly connected to the top of the support frame, an electric telescopic rod provided on the inner wall of the fixed plate, an upper mold fixedly connected to the movable end of the electric telescopic rod, a water inlet fixedly connected to the left side wall of the upper mold, a lower mold provided at the top of the worktable, a water outlet fixedly connected to the right side wall of the lower mold, a connecting pipe fixedly connected to the top of the lower mold, a rubber ring contacting the inner wall of the upper mold, a movable mechanism provided on the inner wall of the upper mold, a filter plate inserted into the inner wall of the upper mold, and a limit component provided at the top of the upper mold; The movable mechanism includes a protrusion that is slidably connected to the inner wall of the upper mold. A movable column is fixedly connected to the outer wall of the protrusion. A through groove is opened on the inner wall of the movable column. The top of the protrusion is elastically connected to the upper mold through a movable spring.

[0006] As a further description of the above technical solution: The limiting component includes an insert block, which is slidably connected to the top of the upper mold, and the right sidewall of the insert block is elastically connected to the upper mold via a moving spring.

[0007] As a further description of the above technical solution: The connecting pipe is inserted into the inner wall of the upper mold.

[0008] As a further description of the above technical solution: The rubber ring is fixedly connected to the inner wall of the moving column, and the top end of the connecting tube is in contact with the bottom end of the moving column.

[0009] As a further description of the above technical solution: The insert is inserted into the inner wall of the filter plate.

[0010] As a further description of the above technical solution: The right sidewall of the insert block is fixedly connected to one end of the movable spring, and the other end of the movable spring is fixedly connected to the right inner wall of the upper mold.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the upper and lower molds can be simultaneously water-cooled when the device closes the mold, which improves the cooling efficiency. At the same time, the through slot is automatically blocked after the mold opens, which prevents the cooling water of the upper mold from dripping and contaminating the product in the lower mold, thus further ensuring product quality.

[0012] 2. In this utility model, when the first set of filter screens on the filter plate is clogged, it can be quickly and manually switched to the second set of filter screens without stopping the machine and affecting production efficiency. Moreover, the spare filter plate can be replaced in advance before the next start-up to ensure the continuous and stable operation of the device. Attached Figure Description

[0015] 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.

[0016] Reference Figures 1-3 This utility model provides an embodiment of a cooling structure for a multi-cavity thermoforming mold for an aviation cup, including a workbench 1. A support frame 2 is fixedly connected to the top of the workbench 1, and the support frame 2 provides connection and support for a fixed plate 3. A fixed plate 3 is fixedly connected to the top of the support frame 2, and an electric telescopic rod 4 is provided on the inner wall of the fixed plate 3. The electric telescopic rod 4 is a mechanical device that converts electrical energy into linear reciprocating motion (telescopic action) driven by an electric motor. An upper mold 6 is fixedly connected to the movable end of the electric telescopic rod 4, and the left side wall of the upper mold 6 is fixedly connected to the upper mold 6. The upper mold 6 and the lower mold 5 are fixedly connected to the water inlet 7. The upper mold 6 and the lower mold 5 work together to process the raw materials (such as metal, plastic, rubber, etc.) into products or semi-finished products of a specific shape through pressure, temperature or injection molding processes. The upper mold 6 and the lower mold 5 are both provided with cavities to facilitate the flow of cooling water. The lower mold 5 is fixedly connected to the right side wall with a water outlet 8. The lower mold 5 is fixedly connected to the top of the lower mold 5 with a connecting pipe 9. The connecting pipe 9 is a hollow ring. The inner wall of the upper mold 6 is in contact with a rubber ring 14.

[0017] Reference Figures 1-3The rubber ring 14 fills the gap between the movable column 11 and the upper mold 6 to prevent water from overflowing. The inner wall of the upper mold 6 is provided with a movable mechanism. A filter plate 15 is inserted into the inner wall of the upper mold 6. Two sets of filter screens are provided on the filter plate 15. The first set of filter screens is used in the initial state. A limit component is provided at the top of the upper mold 6. The movable mechanism includes a protrusion 12. The protrusion 12 is slidably connected to the inner wall of the upper mold 6. The upper mold 6 has a slot corresponding to the protrusion 12, so that the protrusion 12 can move vertically. The outer wall of the protrusion 12 is fixedly connected to the movable column 11. The inner wall of the movable column 11 has a through groove 13. The through groove 13 is L-shaped. The top of the protrusion 12 is elastically connected to the upper mold 6 through a movable spring 10.

[0018] Reference Figures 3-5 The limiting component includes an insert block 16, which is slidably connected to the top of the upper mold 6. The upper mold 6 has a slot corresponding to the insert block 16, allowing the insert block 16 to move left and right. The right side wall of the insert block 16 is elastically connected to the upper mold 6 via a moving spring 17. The insert block 16 is inserted into the inner wall of the filter plate 15. The filter plate 15 has two sets of slots corresponding to the insert block 16. The right side wall of the insert block 16 is fixedly connected to one end of the moving spring 17, and the other end of the moving spring 17 is fixedly connected to the right inner wall of the upper mold 6. When the insert block 16 moves to the right, the moving spring 17 is compressed. When resetting, the elastic force of the moving spring 17 is used to reset the insert block 16.

[0019] Reference Figure 3 , Figure 6 and Figure 7 The connecting pipe 9 is inserted into the inner wall of the upper mold 6. The upper mold 6 has a slot with the same shape as the connecting pipe 9. A sealing ring is provided on the connecting pipe 9 to prevent water from overflowing from the gap when the moving column 11 moves upward. The rubber ring 14 is fixedly connected to the inner wall of the moving column 11. The top end of the connecting pipe 9 contacts the bottom end of the moving column 11. The connecting pipe 9 will squeeze the moving column 11, causing the moving column 11 to move upward.

[0020] Working principle: When the mold is closed, the electric telescopic rod 4 moves the upper mold 6 downward. During the closing process of the upper mold 6 and the lower mold 5, the connecting pipe 9 contacts and squeezes the moving column 11, causing the moving column 11 to move upward along with the rubber ring 14 and the protrusion 12. The protrusion 12 squeezes the movable spring 10. When the upper mold 6 and the lower mold 5 are closed, the through groove 13 is exposed, and the cavities in the upper mold 6 and the lower mold 5 are in a connected state. When the water source is connected to the water inlet 7, the water flow will be divided into two parts. The water flows into the upper mold 6 and the lower mold 5 respectively, cooling the upper mold 6 and the lower mold 5 simultaneously. The water flows out from the outlet 8. When cooling is complete, the upper mold 6 is moved upward by the electrically controlled telescopic rod 4. As the connecting pipe 9 is no longer in contact with the moving column 11, the moving column 11 and the protrusion 12 are moved downward by the elastic force of the movable spring 10. At this time, the through groove 13 will move downward until it is blocked again, preventing the cooling water in the upper mold 6 from dripping into the interior of the lower mold 5 and contaminating the product.

[0021] When the upper mold 6 and lower mold 5 are undergoing water cooling, if the first set of filter screens on the filter plate 15 becomes clogged, manually move the insert block 16 to the right. The insert block 16 will compress the moving spring 17, at which point the insert block 16 will separate from the first slot on the filter plate 15. Manually move the filter plate 15 downwards. When the second set of filter screens coincides with the water inlet 7, the insert block 16 will coincide with the second slot on the filter plate 15. Manually release the insert block 16, and use the elasticity of the moving spring 17 to guide the insert block 16 into the slot of the filter plate 15. In the process, the filter plate 15 is limited, allowing the device to work continuously and avoiding downtime for filter replacement, which would affect production efficiency. Before the next start-up, the operator can prepare the filter plate 15 to be replaced, and then manually move the insert block 16 to the right. When the insert block 16 separates from the groove of the filter plate 15, the operator can manually remove the previous set of filter plates 15, and then manually align the second set of filter plates 15 and insert them into the groove of the upper mold 6, so that the insert block 16 can be inserted into the groove of the filter plate 15, thus completing the limitation of the filter plate 15.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
