Description

Technical Field

[0001] The utility model relates to the technical field of insulator moulds, in particular to an insulator mould ejection structure and an insulator mould having the same. Background Art

[0002] Insulator molds are used to prepare insulator products. The rubber material is injected into the mold cavity of the insulator mold to form movable insulator products. After the insulator product is made, it is necessary to eject the insulator product from the mold cavity through the ejection component.

[0003] In order to solve the problem of the rubber material being stuck, some ejection components are currently equipped with an ejector block at the lower module. The upper surface of the ejector block is flush with the lower module. When the insulator product needs to be ejected, the ejector block is driven to move upward to achieve smooth ejection of the insulator product. However, such ejection components require a large space and are only suitable for preparing insulator molds with a large distance between two umbrella leaves or a large umbrella leaf angle.

[0004] If you need to prepare an insulator product with a small distance between two umbrella leaves or a small angle of the umbrella leaves, the ejector block of the ejector component will affect the injection space of the mold cavity. If you need to avoid the impact of the ejector block on the injection space, you need to cut the upper surface of the ejector block according to the shape of the umbrella leaves, but cutting is difficult, and during the ejection process, the force point of the insulator product affected by the ejector block is located at the umbrella leaves. The strength of the umbrella leaves is relatively small, and the ejection action may cause damage to the umbrella leaves. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an insulator mold ejection structure and an insulator mold having the same.

[0006] The solution of the utility model to solve the technical problem is:

[0007] An insulator mold ejection structure comprises an ejector block, wherein the ejector block comprises a middle section, an inclined section, a transition section and a driving section, wherein the middle section is extended left and right, the inclined section is symmetrically arranged on the left and right sides of the middle section, the transition section is symmetrically arranged on the left and right sides of the middle section and extends left and right, the transition section is arranged on the front side or the rear side of the middle section, the inclined section extends obliquely from the middle section to the inner side of the transition section, and the driving section is symmetrically arranged on the left and right sides of the middle section and connected to the outer side of the transition section.

[0008] The utility model has at least the following beneficial effects: when in use, the middle section is located at the core rod of the insulator product, the transition section is located at the outer edge of the leaf of the insulator product, and the inclined section is located between two adjacent leaves, so as to avoid the mold cavity for forming the leaf of the insulator product, and is suitable for preparing an insulator mold for an insulator product with a small interval between two leaves or a small leaf angle, so as to avoid the ejector block interfering with the mold cavity and affecting the appearance of the insulator product; during the ejection process, the ejector block applies a force to the core rod position of the insulator product, so as to avoid the ejector block applying a force to the leaf and causing the leaf to break or be damaged; in addition, since the inclined sections, transition sections and driving sections on the left and right sides of the middle section are symmetrically arranged, during the ejection process, the force balance on the left and right sides of the insulator product can be ensured, so that the demoulding action is smoother and the insulator product is avoided from being damaged during the demoulding process.

[0009] As a further improvement of the above technical solution, a groove opening upward is provided in the middle of the middle section, and the inner wall surface of the groove is an arc surface. The inner wall surface of the groove can abut and match with the core rod of the insulator product, which can increase the contact area between the top block and the insulator product and ensure the stability of the insulator product ejection.

[0010] As a further improvement of the above technical solution, the width of the driving section in the front-to-back direction is greater than the width of the transition section in the front-to-back direction. This arrangement allows the driving section of the top block to have more installation and connection space, so that the operator can drive the top block manually or automatically.

[0011] As a further improvement of the above technical solution, it also includes a linear drive component, the output end of which is connected to the drive section to drive the ejector block to move in the up and down direction. The setting of the linear drive component can replace manual ejection of the insulator product, improve the automation of insulator production, reduce labor costs, and improve the production efficiency of insulator products.

[0012] As a further improvement of the above technical solution, a connecting block is provided at the output end of the linear drive component, and the connecting block is detachably connected to the driving section. Such a configuration is conducive to the maintenance or replacement of the linear drive component and the top block, so as to ensure the driving accuracy of the linear drive component and the accuracy of the top block.

[0013] As a further improvement of the above technical solution, the driving section is provided with a connecting groove, and the connecting block is provided with a protrusion, and the protrusion is engaged with the connecting groove. The protrusion is inserted into the connecting groove, and the groove wall of the connecting groove can limit the protrusion and play a fool-proof role, so that the operator can connect and install the connecting block and the top block.

[0014] As a further improvement of the above technical solution, the connection groove extends in the front-to-back direction and penetrates the front and rear walls of the driving section. This arrangement makes it easier to insert and remove the protrusion, thereby improving the connection efficiency between the connection block and the top block.

[0015] An insulator mold comprises a lower mold block and an insulator mold ejection structure as described in any one of the above technical solutions, wherein the lower mold block is provided with an upwardly open mounting groove, and an ejection block of the insulator mold ejection structure is arranged in the mounting groove. Since the insulator mold is provided with the insulator mold ejection structure, it is convenient to prepare an insulator product with a small interval between two umbrella leaves or a small umbrella leaf angle, and the manufactured insulator product can be ejected smoothly to meet the needs of users.

[0016] As a further improvement of the above technical solution, the driving section of the top block extends out from the left and right sides of the lower module, and there is a gap between the left and right side walls of the lower module. In this way, when the top block moves up and down relative to the lower module, the friction between the top block and the lower module can be reduced, thereby reducing energy consumption.

[0017] As a further improvement of the above technical solution, the lower module and the insulator mold ejection structure are respectively provided with two groups, the two groups of the lower modules are arranged on the left and right, the two ejection blocks are respectively arranged in the installation grooves of the two lower modules, and the driving sections of the two ejection blocks are connected. With such an arrangement, the insulator mold can prepare two groups of insulator products at the same time, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0030] Reference Figures 1 to 5The embodiment of the utility model proposes an insulator mold ejection structure, which is applied to the insulator mold. It can solve the interference problem of the ejection component on the mold cavity 310 in the existing insulator mold, thereby realizing the ejection of the insulator product without changing the insulator mold cavity 310, especially facilitating the ejection of the insulator product with a small distance between two umbrella leaves or a small umbrella leaf angle.

[0031] The insulator mold ejection structure of the present embodiment includes an ejector block 100, which can contact the insulator product and eject the insulator product from the insulator mold. Specifically, the ejector block 100 includes a middle section 110, an inclined section 120, a transition section 130 and a drive section 140, wherein the inclined section 120, the transition section 130 and the drive section 140 are each provided with two sections, with the middle section 110 as the center, the two inclined sections 120 are symmetrically arranged on the left and right sides of the middle section 110, the two transition sections 130 are symmetrically arranged on the left and right sides of the middle section 110, the two drive sections 140 are symmetrically arranged on the left and right sides of the middle section 110, the left and right ends of the center end are respectively connected to the inner ends of the two inclined sections 120, the outer ends of the two inclined sections 120 are respectively connected to the inner ends of the two transition sections 130, and the inner ends of the two drive sections 140 are respectively connected to the outer ends of the two transition sections 130.

[0032] It is worth noting that the middle section 110 and the transition section 130 are both extended in the left-right direction, and the middle section 110 and the transition section 130 are not on the same straight line. The transition section 130 is located at the front side or the rear side of the middle section 110, and the inclined section 120 extends obliquely from the middle section 110 to the inner side of the transition section 130 to achieve the connection between the transition section 130 and the middle section 110.

[0033] It can be understood that, with such an arrangement, when in use, the middle section 110 can be installed in the middle of the mold cavity 310 of the insulator mold, that is, at the position of the core rod, and the transition section 130 can be installed on the side of the mold cavity 310 of the insulator mold, that is, at the outer edge of the umbrella leaf. The mold cavity 310 of the umbrella leaf forming the insulator product is avoided by the inclined section 120. Especially for insulator products with a small interval between two umbrella leaves or a small umbrella leaf angle, the setting of the inclined section 120 can prevent the top block 100 from passing through the mold cavity 310 and affecting the shape of the insulator product to be formed.

[0034] Since the inclined sections 120, transition sections 130 and driving sections 140 on the left and right sides of the middle section 110 are symmetrically arranged, the force balance on the left and right sides of the insulator product can be ensured during the ejection process, making the demoulding action smoother and avoiding damage to the insulator product during the demoulding process.

[0035] In this embodiment, in order to avoid the core rod placed in the middle of the mold cavity 310, a groove 111 is provided at the middle section 110 of the top block 100. The groove 111 is provided on the upper surface of the middle section 110 and is opened upward. The inner wall surface of the groove 111 is a circular arc surface.

[0036] When in use, the inner wall surface of the groove 111 can abut and match the core rod of the insulator product, which can increase the contact area between the top block 100 and the insulator product, and ensure the stability of the insulator product ejection. In addition, it can prevent the top block 100 from changing the internal shape of the mold cavity 310 and affecting the appearance of the manufactured insulator product.

[0037] It can be understood that the force exerted by the ejection block 100 of this embodiment on the insulator product is concentrated at the position of the core rod, thereby avoiding stress on the leaves of the insulator product. The strength at the core rod position is relatively large, and the ejection action is not easy to damage the insulator product, especially the leaves with lower strength.

[0038] In some embodiments, arc sections are provided at the connections between the middle section 110, the inclined section 120, the transition section 130 and the driving section 140, and smooth connections between the middle section 110, the inclined section 120, the transition section 130 and the driving section 140 are achieved through the arc sections, thereby increasing the strength of the entire ejection block 100 and ensuring the stability of the ejection action.

[0039] It is understandable that by controlling the driving section 140 to move up and down, the top block 100 can be moved up and down, thereby realizing the ejection and demoulding action of the insulator product. The top block 100 can be ejected manually or automatically.

[0040] In some embodiments, the width of the driving section 140 of the top block 100 along the front-to-back direction is greater than the width of the transition section 130 along the front-to-back direction. It is understandable that such a configuration can allow the driving section 140 of the top block 100 to have more installation and connection space, so that the operator can drive the top block 100 manually or automatically.

[0041] In this embodiment, the insulator mold ejection structure also includes a linear drive component, the output end of the linear drive component is connected to the drive section 140, and under the driving action of the linear drive component, the ejector block 100 can move in the up and down directions, thereby driving the insulator product located on the ejector block 100 to be ejected upward, thereby realizing automatic demolding of the insulator product.

[0042] It can be understood that the provision of the linear drive component can replace manual ejection of the insulator product, improve the automation of insulator production, reduce labor costs, and improve the production efficiency of insulator products.

[0043] It is understandable that the linear drive component can be a pneumatic cylinder, an oil cylinder, an electric cylinder, etc., which is not specifically limited here.

[0044] In some embodiments, a connection block 200 is provided at the output end of the linear drive component, and the connection block 200 is detachably connected to the drive section 140 .

[0045] In this embodiment, the connecting block 200 and the driving section 140 of the top block 100 are detachably connected by bolts. After using the insulator mold ejection structure of this embodiment, the connecting block 200 and the top block 100 can be separated, which is beneficial for maintenance or replacement of the linear drive component and the top block 100 to ensure the driving accuracy of the linear drive component and the accuracy of the top block 100.

[0046] In this embodiment, the driving section 140 is provided with a connection groove 141, which is provided on the upper surface of the driving section 140 and is opened upward. The connection block 200 is provided with a protrusion, which is provided on the lower surface of the connection block 200 and protrudes downward. When connecting the driving section 140 and the connection block 200, the protrusion is inserted downward into the connection groove 141, and the groove wall of the connection groove 141 can limit the protrusion and play a fool-proof role, so that the operator can connect and install the connection block 200 and the top block 100.

[0047] In this embodiment, the connection groove 141 is extended in the front-to-back direction, and the front and rear ends of the connection groove 141 respectively penetrate the front wall surface and the rear wall surface of the driving section 140. Such a configuration makes it easier to insert and remove the protrusion, thereby improving the connection efficiency between the connection block 200 and the top block 100.

[0048] It can be understood that the connecting blocks 200 on the two driving sections 140 on the left and right sides of the middle section 110 can be connected to a linear driving component at the same time, and the left and right ends of the top block 100 can be driven simultaneously by a linear driving component to ensure the smooth up and down movement of the top block 100.

[0049] On the other hand, refer to Figure 4 and Figure 5 The utility model embodiment also proposes an insulator mold, which includes the insulator mold ejection structure proposed in any one of the above embodiments, and can prepare insulator products with a small interval between two umbrella leaves or a small umbrella leaf angle to meet user needs.

[0050] It is understandable that the insulator mold also includes an upper module and a lower module 300. When in use, the upper module and the lower module 300 are molded together to form a mold cavity 310. The operator injects glue into the mold cavity 310. After the glue is shaped by the mold cavity 310, an insulator product can be obtained.

[0051] In this embodiment, the lower module 300 is provided with a mounting groove, which is opened upward, and the top block 100 of the insulator mold ejection structure is installed in the mounting groove. In the process of closing the mold to prepare the insulator product, the upper surface of the top block 100 is flush with the upper surface of the lower module 300. When the insulator product is finalized, the upper module is opened, and the top block 100 is driven to move upward, so that the upper surface of the top block 100 protrudes upward from the upper surface of the lower module 300, and the insulator product located in the mold cavity 310 is ejected.

[0052] It is understandable that the two driving sections 140 of the top block 100 are respectively arranged on the left and right sides of the lower module 300, so that the operator can drive the driving section 140 of the top block 100. In this embodiment, a certain gap is left between the driving section 140 and the left wall surface or the right wall surface of the lower module 300. In this way, when the top block 100 moves up and down relative to the lower module 300, the friction between the top block 100 and the lower module 300 can be reduced, thereby reducing energy consumption.

[0053] In some embodiments, in one insulator mold, multiple groups of lower modules 300 are provided, and multiple groups of upper modules are also provided accordingly. In this way, multiple insulator products can be prepared simultaneously in one insulator mold. In this embodiment, two groups of lower modules 300 and two groups of upper modules are provided in one insulator mold, and two insulator products can be prepared simultaneously.

[0054] It can be understood that for an insulator mold provided with two groups of lower modules 300, its insulator mold ejection structure is also provided with two groups, the two groups of lower modules 300 are arranged left and right, and the ejection blocks 100 in the two insulator mold ejection structures are respectively arranged in the installation grooves of the two lower modules 300, and the driving sections 140 of the two ejection blocks 100 are connected to each other. Such an arrangement enables the two ejection blocks 100 to be driven by a linear driving component, thereby reducing the number of driving sources.

[0055] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
