Description

Technical Field

[0001] This invention relates to the field of demolding, and more specifically to a template cooling and demolding device. Background Technology

[0002] The conventional hot pressing process is as follows: the template is automatically heated and then pushed into a press for pressing (the template has several forming holes penetrating the upper and lower surfaces). After pressing, the template is ejected. Next, the template is moved to a cooling station for cooling. Then, the cooled template is moved to a stripping station, where the product is ejected from the forming holes of the template by a stripping device. In the current conventional hot pressing process, after the product is hot-pressed on the template, it needs to pass through the cooling station and the stripping station in sequence, which is cumbersome and affects production efficiency. On the other hand, during the demolding process in the stripping device, the demolding jig of the stripping device is prone to jamming the template. This causes the template to be lifted upwards during the upward movement of the demolding jig, resulting in the template falling midway. This midway fall not only damages the template itself but also easily damages the ejected product.

[0003] For example, Chinese Patent Publication No. CN116190087A, entitled "An Automatic Hot Pressing System and Method for Inductors," includes: multiple hot pressing devices, each including an implanter, a powder filler, at least one hot press, and a demolding machine; a conveying system including a transport mechanism and a transfer mechanism associated with each hot pressing device; and a controller connected to the conveying system and the hot pressing devices, used to control the transport mechanism to transfer the molding die between the areas of each hot pressing device, and to control each hot pressing device to perform the implantation, powder filling, hot pressing, and demolding processes to prepare an inductor preform. While this application can improve production efficiency and stability, the demolding and cooling processes are still separate. The product is cooled first and then transported to the demolding machine area via conveyor belt for demolding. This process is cumbersome and affects production efficiency, as the product needs to pass through the cooling station and the stripping station sequentially after hot pressing. Furthermore, it does not solve the problem that the demolding fixture of the stripping device can easily get stuck on the template during demolding, causing the template to fall midway and damage itself, and potentially breaking the demolded product. Summary of the Invention

[0004] The primary objective of this invention is to provide a template cooling and demolding device that simplifies the operational steps after hot pressing of a product, thereby improving production efficiency.

[0005] The second objective of this invention is to provide a template cooling and demolding device that can effectively solve the problem that during the demolding process, the demolding fixture easily jams the template and causes it to rise, resulting in the template falling during the rise and causing damage to the template itself and easily damaging the demolded product.

[0006] The technical solution of this invention is: A template cooling and demolding device, comprising: frame; The template support includes a support surface for supporting the template and a limiting structure for limiting the template. A cooling device, comprising an air inlet for blowing air to cool a template supported on a support surface; A demolding fixture, the bottom surface of which is provided with several demolding protrusions for ejecting the product from the forming hole of the template; The lifting device, mounted on the frame, drives the demolding fixture to move up and down. This design integrates template cooling and demolding. Once the template is supported on the support surface and limited by the limiting structure, it is first cooled by air blowing through the air vents of the cooling device. Then, the lifting device lowers the demolding fixture, and the product is ejected from the template's forming hole via the demolding protrusion. This eliminates the need for transferring the template between the cooling and demolding stations, simplifying the post-hot-pressing process and improving production efficiency.

[0007] Preferably, the system also includes a template locking element, which comprises a template locking portion located above the support surface. When the template is supported on the support surface and limited by the limiting structure, the template locking portion is positioned above the template to prevent the demolding fixture from lifting the template. Thus, during the demolding process, even if the demolding fixture easily gets stuck on the template, the template will separate from the demolding fixture and remain in place due to the blocking effect of the template locking portion. This effectively solves the problem that during demolding, the demolding fixture easily gets stuck on the template and lifts it, causing the template to fall during the ascent, resulting in damage to the template itself and potentially breaking the ejected product.

[0008] Preferably, the template locking part is a locking plate, and the locking plate is parallel to the support surface. This helps the locking plate prevent the demolding fixture from driving the template upward.

[0009] Preferably, the limiting structure includes a limiting element and two parallel side limiting surfaces. The supporting surface is located between the left and right limiting surfaces, with a template inlet formed on one side between the left and right limiting surfaces, and the limiting element located on the other side between the left and right limiting surfaces. In actual operation, the template enters through the template inlet and is supported on the supporting surface. Then, the template moves inward along the left and right limiting surfaces until it abuts against the limiting element, thereby achieving the limiting and positioning of the template.

[0010] Preferably, the limiting element is equipped with a template sensor. When the template sensor detects the template, the air outlet blows air onto the template for cooling.

[0011] Preferably, the fixture also includes a mechanism to prevent accidental obstruction, which comprises: Horizontal guide sleeve, the horizontal guide sleeve is fixed on the frame. The guide hole is set on the limiting element and is parallel to the axis of the horizontal guide sleeve; The sliding contact rod is slidably set in the guide hole. The sliding direction of the sliding contact rod is parallel to the side limiting surface, and the front end of the sliding contact rod faces the template inlet. The fixture stop bar is slidably mounted on the horizontal guide sleeve. The fixture stop bar is located below the demolding fixture. The fixture stop bar and the sliding contact bar are connected by a connector. The spring causes the front end of the sliding contact rod to move towards the outside of the guide hole in the direction of the template entrance.

[0012] When the front end of the sliding contact rod moves to the outside of the guide hole in the direction of the template inlet under the action of the spring, part of the jig stop bar is located directly below the demolding jig to prevent the demolding jig from descending; When the front end of the sliding contact rod moves into the guide hole, the jig stop bar is located on the outside of the demolding jig, and the lifting device can drive the demolding jig to move up and down.

[0013] During template positioning, the operator is required to push the template inward along the left and right limiting surfaces until the template abuts against the limiting element. This allows the demolding protrusion to enter the corresponding forming hole and eject the product from the forming hole as the lifting device lowers the demolding fixture. However, in actual operation, due to negligence, the template may not be pushed in place or abut against the limiting element, causing the demolding protrusion to collide with the template during the descent of the demolding fixture, resulting in damage to the demolding protrusion and / or the template. To solve this problem, this solution includes a fixture anti-misalignment blocking mechanism. Specifically, during template positioning, when the operator pushes the template inward along the left and right limiting surfaces and the mold... When the plate rests against the limiting element, the template will push the front end of the sliding contact rod into the guide hole. At the same time, the sliding contact rod will drive the fixture stop rod to the outside of the demolding fixture. After that, the fixture stop rod will not affect the lifting and lowering of the demolding fixture. The lifting device can drive the demolding fixture to lift and lower, pushing out the product in the forming hole of the template, realizing product unloading. If the template does not rest against the limiting element and there is a gap between the template and the limiting element, a part of the fixture stop rod will be located directly below the demolding fixture to block the demolding fixture from descending. At this time, during the process of the lifting device driving the demolding fixture to descend, it will be blocked by the fixture stop rod, thereby avoiding the demolding protrusion from colliding with the template and causing damage to the demolding protrusion and / or template.

[0014] Preferably, the demolding fixture includes a demolding mold frame and a demolding template. The demolding template is fixed to the bottom surface of the demolding mold frame, and the demolding protrusion is provided on the lower surface of the demolding template. This facilitates the actual manufacturing and installation of the demolding fixture, and the demolding template can be replaced as needed.

[0015] Preferably, the template support includes two vertical support plates, left and right, with the support surface located between the two vertical support plates. Each of the left and right vertical support plates is provided with an air inlet. Cooling the template by blowing air through the air inlets on the left and right vertical support plates improves cooling efficiency.

[0016] Preferably, the lifting device is a lifting cylinder, and the frame includes a vertical guide rod, along which the demolding fixture moves up and down.

[0017] The beneficial effects of this invention are: Firstly, it is a template cooling and demolding device that simplifies the operation steps after hot pressing of products, thereby improving production efficiency.

[0018] Secondly, it can effectively solve the problem that during the demolding process, the demolding fixture easily gets stuck on the template and causes it to rise, resulting in the template falling during the rise, which damages the template itself and easily breaks the demolded product.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a template cooling and demolding device includes a frame 1, a template support 2, a cooling device 6, a demolding fixture 3, and a lifting device 4. The template support 2 includes a support surface 2.3 for supporting the template 5 and a limiting structure for limiting the template. The support surface is horizontally distributed. The cooling device includes an air inlet 6.1 and an air inlet pipe connected to the air inlet. The air inlet blows air to cool the template supported on the support surface. The bottom surface of the demolding fixture has several demolding protrusions, each corresponding to a forming hole on the template 5. The demolding protrusions are used to eject the product from the forming hole of the template. The lifting device 4 is mounted on the frame and drives the demolding fixture to move up and down. The lifting device is a lifting cylinder, a lifting hydraulic cylinder, or a lifting electric cylinder. In this embodiment, the lifting device is a lifting cylinder.

[0025] In this embodiment, the template cooling and demolding device integrates cooling and demolding. After the template is supported on the support surface and limited by the limiting structure, it is first cooled by air through the air blowing port of the cooling device. Then, the demolding fixture is lowered by the lifting device, and the product is pushed out of the forming hole of the template by the demolding protrusion, thus realizing the product demolding of the template. In this way, the transfer operation of the template between the cooling station and the demolding station is eliminated, the operation steps after the product is hot-pressed are simplified, thereby improving production efficiency.

[0026] Specifically, such as Figure 1 As shown, the frame 1 includes a base 1.1, a top frame 1.2, a vertical guide rod 1.3, and a vertical connecting rod 1.4 connecting the base and the top frame. A grating is mounted on the frame. The vertical guide rod is fixed to the base. The demolding fixture moves up and down along the vertical guide rod. A lifting cylinder is mounted on the top frame. The demolding fixture 3 includes a stripping mold frame 3.1 and a stripping template 3.2. The piston rod of the lifting cylinder is connected to the stripping mold frame. The stripping template is fixed to the bottom surface of the stripping mold frame. Demolding protrusions are provided on the lower surface of the stripping template. This facilitates the actual fabrication and installation of the demolding fixture, and the stripping template can be replaced as needed.

[0027] like Figure 2 As shown, the template support 2 includes two vertical support plates 2.1, one on the left and one on the right. The two vertical support plates are parallel to each other and are fixed to the base of the frame with bolts. The space between the two vertical support plates forms a material discharge cavity. One side of the two vertical support plates is connected by a connecting plate located on the same side of both plates. Each of the two vertical support plates has an air inlet 6.1 at its lower part. The air inlet communicates with the material discharge cavity between the two vertical support plates. Air is blown onto the template through the air inlets on the two vertical support plates for cooling, which helps improve cooling efficiency.

[0028] Furthermore, such as Figure 2 , Figure 3As shown, the limiting structure includes a limiting element 2.2 and two parallel side limiting surfaces 2.4. A support surface is located between the left and right limiting surfaces. In this embodiment, the support surface is located between two vertical support plates, and each of the two opposite sides of the two vertical supports has a stepped surface, which constitutes the support surface. The side limiting surfaces correspond one-to-one with the vertical support plates, are set on the corresponding vertical support plates, are parallel to the vertical support plates, and are located above the stepped surfaces. A template entrance is formed on one side between the left and right limiting surfaces. The limiting element is located on the other side between the left and right limiting surfaces. A grating is located in front of the template entrance. The template entrance and the limiting element are located on opposite sides of the two vertical support plates. In this embodiment, a connecting plate constitutes the limiting element. In actual operation, the template enters through the template entrance and is supported on the support surface. Then, the template moves inward along the left and right limiting surfaces until it abuts against the limiting element, thereby achieving the limiting and positioning of the template. On the other hand, the template is supported on the support surfaces of the two vertical support plates on the left and right. The space between the support surfaces of the two vertical support plates is the unloading space. When the lifting device drives the demolding fixture to descend and pushes out the product in the forming hole of the template through the demolding protrusion, the product falls through the unloading space, realizing the product unloading of the template.

[0029] Furthermore, the limiting element is equipped with a template sensor. When the template sensor detects the template, the air outlet blows air onto the template for cooling.

[0030] Furthermore, such as Figure 2 As shown, a template cooling and demolding device further includes a template locking element 7. The template locking element includes a template locking portion 7.1 located above the support surface 2.3. The template locking portion is a locking plate, and the locking plate is parallel to the support surface. In this embodiment, template locking elements are installed on the tops of both vertical support plates. The template locking elements are installed on the corresponding vertical support plates by bolts. When the template is supported on the support surface and limited by the limiting structure (the template being limited by the limiting structure means that the template is located between the left and right limiting surfaces and the template abuts against the limiting element), the template locking portion is located above the template to prevent the demolding fixture from driving the template upward. Thus, during the unmolding process, even if the demolding fixture easily gets stuck on the template, the template will separate from the demolding fixture and remain in place due to the obstruction of the template locking part during the upward movement of the demolding fixture. This effectively solves the problem that the demolding fixture easily gets stuck on the template during the unmolding process, causing the template to rise and fall during the upward movement, resulting in damage to the template itself and easily damaging the unmolded product.

[0031] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that... like Figure 4As shown, a template cooling and demolding device further includes a fixture anti-misoperation blocking mechanism 8. The fixture anti-misoperation blocking mechanism includes a horizontal guide sleeve 8.1, a fixture stop bar 8.2, a guide hole 8.3, a sliding contact rod 8.4, and a spring. The horizontal guide sleeve 8.1 is fixed to the frame. The guide hole is located on the limiting element 2.2. The guide holes are horizontally distributed and pass through the limiting element. The axis of the guide hole is parallel to the axis of the horizontal guide sleeve.

[0032] The jig stop is slidably mounted on the horizontal guide sleeve. The sliding contact rod is slidably mounted within the guide hole. The sliding direction of the sliding contact rod is parallel to the side limiting surface. The front end of the sliding contact rod faces the mold plate inlet. The jig stop is located below the demolding jig, and the jig stop and the sliding contact rod are connected by connector 8.5. The connector and the mold plate inlet are located on both sides of the limiting element. When the mold plate is supported on the support surface, the jig stop is located above the mold plate. The jig stop is equipped with a limiting block 8.6.

[0033] The front end of the sliding contact rod moves towards the outside of the guide hole in the direction of the template entrance under the action of the spring. In this embodiment, the limiting block abuts against the horizontal guide sleeve under the action of the spring. When the limiting block abuts against the horizontal guide sleeve, a part of the jig stop bar is located directly below the demolding jig to prevent the demolding jig from descending.

[0034] When the front end of the sliding contact rod moves to the outside of the guide hole in the direction of the template entrance under the action of the spring, part of the jig stop bar is located directly below the demolding jig to prevent the demolding jig from descending.

[0035] When the front end of the sliding contact rod moves into the guide hole, the jig stop bar is located on the outside of the demolding jig, and the lifting device can drive the demolding jig to move up and down.

[0036] During template positioning, the operator is required to push the template inward along the left and right limiting surfaces until it abuts against the limiting element. This allows the demolding protrusion to enter the corresponding forming hole and push the product out during the descent of the demolding fixture by the lifting device. However, in actual operation, due to negligence, the template may not be pushed in place and may not abut against the limiting element. This can cause the demolding protrusion to collide with the template during the descent of the demolding fixture by the lifting device, resulting in damage to the demolding protrusion and / or the template. To solve this problem, this solution includes a fixture anti-misoperation blocking mechanism. Specifically, during template positioning… When the operator pushes the template inward along the left and right limiting surfaces and makes the template abut against the limiting element position, the template will push the front end of the sliding contact rod to move into the guide hole. At the same time, the sliding contact rod drives the jig stop rod to move to the outside of the demolding jig. After that, the jig stop rod will not affect the lifting of the demolding jig. The lifting device can drive the demolding jig to lift up and down, push out the product in the forming hole of the template, and realize the product unloading. If the template does not rest against the limiting element and there is a gap between the template and the limiting element, then under the action of the spring, part of the jig stop bar is located directly below the demolding jig to prevent the demolding jig from descending. At this time, during the process of the lifting device driving the demolding jig to descend, it will be blocked by the jig stop bar, thereby avoiding the demolding protrusion from colliding with the template and causing damage to the demolding protrusion and / or template.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
