AI Technical Summary
Existing molds present challenges when performing angled core pulling on the front mold and simultaneous sliding core pulling and angled core pulling on the rear mold, especially the problem of the angled core being clamped by the parallel area of the product after being pulled out, making it difficult to demold.
A fast ejection mold with inclined core pulling of both front and rear molds was designed. By setting elastic components and damping openers and closers between the front mold and the upper panel, the upper panel moves before the front mold when the mold opens, which drives the inclined core pulling component on the sprue bushing to pull the core first. The subsequent slider core pulls the core, and the slider core on the rear mold plate is driven to slide through the inclined guide post. The circumferential core pulling and inner inclined core pulling of the rear mold are safely separated by the inclined sliding slider and the inclined groove. At the same time, the mold structure is optimized by using inclined ejector and fast ejection components.
This method enables the smooth demolding of the front mold with angled pull and the rear mold with slider core pulling, avoiding the problem of the angled mold core being stuck by the product and ensuring smooth demolding of the injection molded parts with a smooth surface.

Description
Technical Field
[0001] This utility model belongs to the field of mold technology, and in particular relates to a fast ejection mold in which both the front and rear molds are inclined. Background Technology
[0002] A mold is a precision tool or device used in industrial production to form products. Its core principle is to use its specific cavity or surface to fill the cavity with a flowing or plastic material under certain pressure and temperature conditions. After cooling, solidification or reaction, a product is formed that is completely consistent with the shape of the cavity.
[0003] There is a product with a Z-shaped undercut structure inside the waist-shaped holes on both sides of the front mold, and the outer appearance requirements are high, requiring the use of circumferential slider core pulling. At the same time, there is a hole and pillar structure on one side of the inner cavity of the rear mold. Therefore, this mold not only needs to consider the timing of the front mold's oblique core pulling first, but also requires the rear mold to perform oblique core pulling action in the circumferential direction while performing slider core pulling. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a fast ejection mold with both front and rear molds angled, which solves the problems of achieving angled ejection before mold exit on the front mold and simultaneous slider core pulling and angled core pulling on the rear mold.
[0005] It enables the inclined extraction of the front mold first and solves the problem that the inclined mold core is still clamped by the parallel area of the product after the undercut structure is pulled out, making it difficult to demold.
[0006] The technical solution of this utility model is as follows: A quick ejection mold with inclined front and rear molds, including an upper panel, a front mold plate, a rear mold plate, mold feet, a lower panel, and an ejection mechanism. A front mold core is provided in the front mold plate, and a rear mold core is provided in the rear mold plate. When the front mold core and the rear mold core are closed, they form an injection cavity. A sprue sleeve is fixedly provided on the upper panel as the injection port of the injection cavity. An elastic element is installed between the upper panel and the front mold plate. A damping opening and closing device is provided between the front mold plate and the rear mold plate. A front mold inclined ejection assembly is provided on the sprue sleeve. The front mold inclined ejection assembly includes a front mold inclined ejection component. An inclined hole for accommodating the front mold inclined ejection component is provided through the front mold core. The front mold inclined ejection component is pulled by the sprue sleeve to move in the inclined hole. A slider core is slidably disposed on the rear template, and the slider core is provided with an inclined hole for the inclined guide post to extend into. The inclined guide post is fixedly disposed on the front template. The rear mold platen is also provided with a rear mold angled pull assembly. The rear mold angled pull assembly is located at the bottom of the slider mold core facing the injection cavity. The rear mold angled pull assembly includes a rear mold angled pull member and an angled pull slider fixedly disposed with the slider mold core. An angled groove is provided on the angled pull slider. A guide angled hole is provided in the rear mold core. One end of the rear mold angled pull member is constrained in the angled groove and slides along the groove direction. The other end passes through the guide angled hole and extends into the injection cavity. The angled groove and the guide angled hole are arranged perpendicular to each other.
[0007] By adopting the above technical solution, by setting elastic components and damping opening and closing devices between the front mold and the upper panel, the upper panel moves before the front mold when the mold opens. This causes the mold angle pulling component set on the sprue bushing, which is fixed to the upper panel, to move before the front mold to pull the core, so that it can safely detach from the undercut position in the Z direction of the product. Then the mold continues to open. Driven by the angled guide pillar, the slider mold core on the rear mold plate slides outward to pull the core. At this time, the angle pulling slider slides with the slider mold core. Since the angle pulling slider is set at the bottom of the slider mold core, it avoids the mold core part inserted into the injection mold cavity. The angle pulling slider drives the rear mold angle pulling component to be pulled out in the direction of the guide angled hole through the angled groove, so that the circumferential core pulling and the inner angle pulling of the rear mold can be safely detached from the product.
[0008] Further features of this invention: The ejection mechanism is disposed in the space formed by the rear template, mold foot, and lower panel. The ejection mechanism includes an upper ejection plate, a lower ejection plate, and an inclined ejector assembly. The upper ejection plate and the lower ejection plate are fixedly connected. The inclined ejector assembly includes an inclined ejector seat vertically fixed to the top of the lower ejection plate. An inclined ejector is disposed on the top of the inclined ejector seat. An inclined guide groove is disposed in the rear template and the rear mold core. The inclined ejector passes through the inclined guide groove into the injection cavity.
[0009] With the above-mentioned further configuration, the inclined ejector, as the ejection structure, not only has the function of pushing the injection molded part outward from the lower ejector plate, but also the part of the inclined ejector that extends into the injection cavity before the injection action can serve as the mold core, combining the mold core function with the ejection function, thus optimizing the internal structure of the mold.
[0010] A further feature of this invention is that the ejection mechanism also includes a quick ejection assembly. The upper ejection plate and the lower ejection plate are sequentially arranged on the lower plate. The quick ejection assembly includes a rocker plate disposed between the upper ejection plate and the lower ejection plate. The two ends of the rocker plate swing around the central pin. The two ends of the rocker plate are respectively provided with a straight ejector pin and a stop rod. The stop rod extends to the space between the upper ejection plate and the rear template.
[0011] By further configuring the above, a rapid ejection component is set up so that when the upper ejection plate and the lower fixed ejection plate move together in the ejection direction, the rapid ejection component moves together with the inclined ejection component in the ejection direction until the abutment rod contacts the bottom of the rear template. At this time, it continues to move in the ejection direction, and the abutment rod squeezes the rocker plate, causing its other end to rise, pushing the straight ejector pin to eject faster than the inclined ejection component, thereby realizing the separation of the product from the parallel area clamped by the two inclined ejectors.
[0012] A further feature of this invention is that the bottom of the upper ejector plate and the top of the lower ejector plate are both recessed to form a plate groove for accommodating the rocker plate. The bottom end of the straight ejector pin is located in the plate groove, and the other end passes through the upper ejector plate, the rear mold plate, and the rear mold core in sequence to extend into the injection cavity. The part of the straight ejector pin located in the plate groove is fitted with a telescopic spring, and the two ends of the telescopic spring abut against the circumferentially protruding head at the bottom end of the straight ejector pin and the top of the plate groove, respectively.
[0013] By further configuring the above, a slot is set between the upper and lower ejector plates to restrict the rocker plate, preventing shaking from affecting the straight ejector. At the same time, the telescopic spring is set so that after the ejection action is completed, the telescopic spring returns to its original position, pushing the straight ejector away from the injection cavity, squeezing the rocker plate downward, and lifting the other end of the connecting rod to complete the reset.
[0014] A further feature of this invention is that the ejection mechanism also includes a material pulling ejector pin fixedly disposed between the upper ejector plate and the lower ejector plate. The material pulling ejector pin passes through the upper ejector plate, the rear mold plate, and the rear mold core in sequence to the injection cavity. The material pulling ejector pin and the injection port are on the same central axis.
[0015] By adopting the above-mentioned further settings, the injection molded material between the sprue bushing and the injection cavity is ejected, allowing it to fall off simultaneously with the product, thus avoiding leaving demolding scratches.
[0016] A further improvement of this invention is that the rear mold inclined pull part is provided with a clearance groove for avoiding the material pulling ejector pin.
[0017] The above-mentioned further design prevents interference between the rear mold angled pull part and the pull ejector pin, and the hollowing out of the middle part of the rear mold angled pull part does not affect its own force-bearing action.
[0018] A further feature of this invention is as follows: a guide post is provided between the top of the lower ejector plate and the bottom of the front template, the guide post passes through the rear template, and a return spring is sleeved on the guide post, with both ends of the return spring abutting against the upper ejector plate and the rear template, respectively.
[0019] With the above-mentioned further configuration, when the mold opens, the lower ejector plate drives the guide pillar to move upward, pushing the front mold to move, which can be used as part of the mold opening force. At the same time, the return spring is set between the upper ejector plate and the rear mold plate. After the thrust of the lower ejector plate is lost, its compressed return spring pushes the upper ejector plate and the lower ejector plate to return to their original positions.
[0020] A further feature of this invention is that the front mold angled extraction component also includes a fixing block, which is fixedly mounted on the sprue sleeve. The bottom of the fixing block is provided with a sliding groove. The top end of the front mold angled extraction component is located in the sliding groove, and the other end passes obliquely through the inclined hole into the injection cavity. The opening at the bottom of the sliding groove contracts inward, and together with the side wall of the sprue sleeve, it constrains the top end of the front mold angled extraction component in the sliding groove.
[0021] By adopting the above-mentioned further configuration, the sliding groove in the fixed block restricts the front mold inclined pull part in the mold opening and closing direction, constrains the movement of the front mold inclined pull part in this direction when there is no mold opening and closing action, and avoids the part inserted into the injection cavity from shaking and affecting the product accuracy.
[0022] A further improvement in this invention is that the inclined surface at the top of the sloping ejector is parallel to the ejector's demolding direction.
[0023] By adopting the above-mentioned further design, it is possible to prevent the inclined surface of the ejector from directly interfering with the injection molded part during demolding, resulting in a smoother surface of the injection molded part after demolding. Attached Figure Description

[0030] like Figure 1-10 As shown, a quick ejection mold with inclined front and rear molds includes an upper panel 1, a front mold plate 2, a rear mold plate 3, mold feet 4, a lower panel 5, and an ejection mechanism 6. The front mold plate 2 is provided with a front mold core 21, and the rear mold plate 3 is provided with a rear mold core 31. When the front mold core 21 and the rear mold core 31 are closed, they form an injection cavity. Both the front mold core 21 and the rear mold core 31 are provided with circulating water channels. The rear mold core 31 may include an insert fixed above itself as the surface of the injection cavity. A sprue sleeve 11 is fixedly provided on the upper panel 1 as the injection port of the injection cavity.
[0031] Elastic components 22 are installed at the four corners between the upper panel 1 and the front template 2. In this embodiment, the elastic components 22 are springs. The four corners of the top of the front template 2 are provided with grooves to accommodate the springs. The two ends of the springs are connected to the bottom surface of the upper panel 1 and the bottom surface of the grooves, respectively. A damping opening and closing device 23 is provided between the front template 2 and the rear template 3, so that the resistance between the front template 2 and the rear template 3 is greater than the resistance between the front template 2 and the upper panel 1. Guide posts are evenly inserted on the upper panel 1, the front template 2 and the rear template 3 to guide the mold opening action. Thus, during the mold opening process after the upper panel 1 is fixed, the upper panel 1 moves first before the front template 2.
[0032] A front mold angled pull assembly 7 is symmetrically arranged on the left and right sides of the sprue sleeve 11. Each front mold angled pull assembly includes a front mold angled pull piece 71 and a fixing block 72. The fixing block 72 is fixedly arranged on the sprue sleeve 11. In this embodiment, the sprue sleeve 11 is divided into an outer sleeve and an inner sleeve. The fixing block 72 is fixed to the inner sleeve part of the sprue sleeve 11. The inner sleeve part of the sprue sleeve 11 is inserted into and fixed at the middle through hole of the outer sleeve of the sprue sleeve 11 and extends into the injection cavity. The front mold core 21 has an inclined hole 22 through which a front mold inclined pull member 71 is accommodated. The inclined hole 22 is inclined outward. The bottom of the fixing block 72 is provided with a sliding groove 721. The opening at the bottom of the sliding groove 721 narrows inward, making the sliding groove 721 have a T-shaped structure. The top end of the front mold inclined pull member 71 is placed in the sliding groove 721, and the other end extends out of the sliding groove 721 and obliquely passes through the inclined hole 22 into the injection cavity. The front mold inclined pull member 71 is constrained by the upper and lower side walls of the sliding groove 721 and the inner and outer sleeve walls of the sprue sleeve 11, so that its top end is placed in the sliding groove 721. After the sprue sleeve 11 moves toward the mold opening direction, it drives the fixing block 72 to move. The fixing block 72 pulls the front mold inclined pull member 71 to move in the inclined hole 22.
[0033] The rear template 3 has sliding slider cores 32 on all four sides. Each slider core 32 has one side extending into the injection cavity and the other side having an inclined hole for the inclined guide post 33 to extend into. The inclined hole is inclined towards the injection cavity along the mold opening direction of the front template 2. One end of the inclined guide post 33 is fixedly set on the front template 2 and the other end extends into the inclined hole on the slider core 32. It should be noted that in this embodiment, the end of the slider core 32 facing the injection cavity can also be fixedly set with a core, which can extend into the injection cavity.
[0034] The rear mold plate 3 is also provided with a rear mold angled pull assembly 8. The rear mold angled pull assembly 8 is located at the bottom end of the slider mold core 32 facing the injection cavity. The rear mold angled pull assembly 8 includes a rear mold angled pull part 81 and an angled pull slider 82 fixedly disposed with the slider mold core 32. The angled pull slider 82 is located at the bottom of the slider mold core 32, avoiding the mold core part inserted into the injection mold cavity. An angled groove 821 is provided on the angled pull slider 82, and a guide angled hole 311 is provided in the rear mold core 31. One end of the rear mold inclined pull member 81 is constrained in the inclined groove 821 and slides along the groove direction, while the other end extends into the injection cavity through the guide inclined hole 311. The inclined groove 821 and the guide inclined hole 311 are set perpendicular to each other. Thus, when the slider mold core 32 slides and pulls the core along with the inclined guide post 33, the inclined pull slider 82 slides together with the slider mold core 32. The inclined pull slider 82 drives the rear mold inclined pull member 81 to be pulled away in the direction of the guide inclined hole 311 through the inclined groove 821, so as to realize the four-way core pulling of the rear mold and the inner inclined pulling are carried out simultaneously.
[0035] The ejection mechanism 6 is disposed in the space formed by the rear template 3, the mold foot 4 and the lower panel 5. The ejection mechanism 6 includes an upper ejection plate 61, a lower ejection plate 62, an inclined ejection component 63 and a quick ejection component 64. The upper ejection plate 61 and the lower ejection plate 62 are arranged sequentially above the lower panel 5. A through hole is provided in the middle of the lower panel 5 for the push rod to push against the lower ejection plate 62 to perform the ejection action during demolding.
[0036] The upper ejector plate 61 and the lower fixed ejector plate 62 are fixedly connected. The inclined ejector assembly 63 includes an inclined ejector seat 631 that is vertically fixed to the top of the lower ejector plate 62. An inclined ejector 632 is provided on the top of the inclined ejector seat 631. An inclined guide groove 312 is provided in the rear mold plate 3 and the rear mold core 31. The inclined ejector 632 goes into the injection cavity through the inclined guide groove 312. An inverted T-shaped groove is provided on the top of the inclined ejector seat 631. The bottom of the inclined ejector 632 and the inverted T-shaped groove structure are used to connect the two. At the same time, after the inclined ejector 632 moves obliquely, it does not affect the left and right sliding of the inclined ejector 632 relative to the inclined ejector seat 631.
[0037] Furthermore, the inclined ejector 632, as an ejection structure, not only has the function of pushing the injection molded part outward from the lower ejector plate 62, but also the part of the inclined ejector 632 that extends into the injection cavity before the injection action can serve as a mold core, combining the mold core function with the ejection function, thus optimizing the internal structure of the mold.
[0038] Furthermore, the inclined surface of the top of the inclined ejector 632 is parallel to the ejection direction of the inclined ejector 632, which can prevent the inclined surface of the inclined ejector 632 from directly interfering with the injection molded part during demolding, and make the surface of the injection molded part smoother after demolding.
[0039] The rapid ejection assembly 64 includes a rocker plate 641 disposed between the upper ejection plate 61 and the lower ejection plate 62. The bottom of the upper ejector plate 61 and the top of the lower ejector plate 62 are both recessed, forming an inter-plate groove 644 for accommodating the rocker plate 641. The rocker plate 641 abuts against the upper and lower walls of the inter-plate groove 644. A round pin is provided in the middle of the rocker plate 641, allowing both ends of the rocker plate 641 to swing up and down around the round pin. A straight ejector pin 642 and an abutment rod 643 are respectively provided at both ends of the rocker plate 641. The abutment rod 643 extends between the upper ejection plate 61 and the rear template 3. The bottom end of the straight ejector pin 642 is located within the inter-plate groove 644, and the other end passes sequentially through the upper ejector plate 61, the rear mold plate 3, and the rear mold core 31 into the injection cavity. A telescopic spring 645 is fitted onto the portion of the straight ejector pin 642 within the inter-plate groove 644. The two ends of the telescopic spring 645 abut against the circumferentially protruding head at the bottom end of the straight ejector pin 642 and the top of the inter-plate groove 644, respectively. After the ejection action is completed, the telescopic spring 645 resets, pushing the straight ejector pin 642 away from the injection cavity, pressing the rocker arm 641 downwards, and causing the other end of the connecting rod 643 to lift, completing the reset.
[0040] When the upper ejector plate 61 and the lower fixed ejector plate 62 move together in the ejection direction, the rapid ejection assembly 64 moves together with the inclined ejector assembly 63 in the ejection direction until the abutment rod 643 contacts the bottom of the rear template 3. At this time, it continues to move in the ejection direction, and the abutment rod 643 squeezes the rocker plate 641, causing its other end to rise, pushing the straight ejector pin 642 to eject the injection molded part faster than the inclined ejector assembly 63, so as to realize the separation of the product from the parallel area of the two inclined ejectors 632.
[0041] With the cooperation of the inclined ejector assembly 63 and the quick ejection assembly 64, when facing the undercut structure on the two inner sides of the rear mold cavity and the 45-degree hole and pillar structure in the center of one side of the rear mold cavity, and the undercut shape on the inner side runs through the entire two inner sides, and the mold core forming area of the rear mold includes the parallel areas of the other two inner sides, the inclined ejector assembly 63 uses the mold core as the ejection structure, and the quick ejection assembly is set on both sides of the inclined ejector seat to cooperate with the ejection of the inclined ejector assembly 63. There is no need to perform core pulling treatment on the inner undercut, thus achieving the avoidance of the inclined ejector action position and the inclined part pulling action of the rear mold.
[0042] Furthermore, the ejection mechanism 6 also includes a pull ejector pin 65 fixedly disposed between the upper ejector plate 61 and the lower ejector plate 62. The pull ejector pin 65 passes through the upper ejector plate 61, the rear mold plate 3 and the rear mold core 31 in sequence to the injection cavity. The pull ejector pin 65 is on the same central axis as the injection port. The pull ejector pin 65 can eject the injection solidified material between the sprue sleeve 11 and the injection cavity, so that it falls off synchronously with the product, avoiding leaving demolding scratches.
[0043] In this embodiment, the rear mold inclined pull member 81 is provided with a clearance groove 811 for avoiding the material pulling ejector pin 65, so as to prevent the rear mold inclined pull member 81 from interfering with the material pulling ejector pin 64, and the hollowing out of the middle part of the rear mold inclined pull member 81 does not affect its own force-bearing action.
[0044] A guide post 9 is provided between the top of the lower ejector plate 62 and the bottom of the front template 3. The guide post 9 passes through the rear template 3. A reset spring 91 is sleeved on the guide post 9. The two ends of the reset spring 91 abut against the upper ejector plate 61 and the rear template 3, respectively.
[0045] When the mold is opened, the lower ejector plate 62 drives the guide post 9 to move upward, pushing the front mold 2 to move, which can be used as part of the mold opening force. At the same time, the return spring 91 is set between the upper ejector plate 61 and the rear mold plate 3. After the thrust of the lower ejector plate 62 is lost, the compressed return spring 91 pushes the upper ejector plate 61 and the lower ejector plate 62 to return to their original positions.
