Description

Technical Field

[0001] This utility model relates to the field of molds, and specifically to a panel handle mold. Background Technology

[0002] In the field of injection molding, panel handles are common components in products such as home appliances, furniture, and automotive interiors. Their structures often feature complex characteristics such as lateral undercuts and curved grooves, posing challenges to mold demolding and overall mold performance. Existing technologies have shortcomings in mold design for such handles: traditional molds often rely on a single ejector pin for ejection. For handles with undercuts, the ejector pin cannot achieve lateral core pulling, which can easily lead to demolding jamming, scratches on the product surface, or deformation.

[0003] Therefore, in order to address the shortcomings of existing computing technologies, it is necessary to design a panel handle mold with a specific structure. Utility Model Content

[0004] This utility model provides a panel handle mold to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A panel handle mold includes: an upper mold base plate, an upper mold, a lower mold, a lower mold base plate, and an ejection mechanism. The upper mold is disposed at the lower end of the upper mold base plate, and the lower mold is disposed at the upper end of the lower mold base plate. The upper mold has an upper mold core inside, and the lower mold has a lower mold core. A handle cavity is provided between the upper mold core and the lower mold core. The ejection mechanism includes an ejector pin, an inclined ejector, a guide block, and a push plate. The push plate is disposed at the upper end of the lower mold base plate, and the guide block is fixed to the bottom of the lower mold. The lower ends of the ejector pin and the inclined ejector are connected to the push plate. The ejector pin and the inclined ejector slide within the lower mold and the lower mold core. The inclined ejector passes through the guide block and is symmetrically arranged in pairs towards the center.

[0006] As a further improvement, the upper mold base plate is provided with a gating channel that connects to the handle cavity.

[0007] In a further improvement, the handle cavity includes a handle cavity one and a handle cavity two. Both handle cavity one and handle cavity two are provided with three sets of spaced-apart ejectors and seven sets of inclined ejectors. The seven sets of inclined ejectors include three sets of symmetrical inclined ejectors and one set of inclined ejectors at the rear end.

[0008] In a further improvement, the head of the sloping top is tilted outwards.

[0009] A further improvement is that the tilt angle of the sloping top is 6 to 10 degrees.

[0010] Compared with the prior art, the beneficial effects of the panel handle mold of this utility model are as follows: By employing the inclined design of the slanted ejector and the precise guidance of the guide block, the vertical ejection force is converted into a lateral core-pulling force, solving the problem of handle-like undercut demolding that traditional ejector pins cannot handle, and avoiding defects such as product scratches and deformation. The guide block provides motion trajectory constraints for the slanted ejector, effectively preventing it from deviating, jamming, or colliding during sliding. At the same time, the synergistic effect of the ejector pin and the slanted ejector makes the ejection force distribution more balanced, reducing the risks of ejector plate tilting and asynchronous ejection.

[0013] The following describes the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0014] Example 1 A panel handle mold includes: an upper mold base plate 1, an upper mold 2, a lower mold 3, a lower mold base plate 4, and an ejection mechanism 5. The upper mold 2 is disposed at the lower end of the upper mold base plate 1, and the lower mold 3 is disposed at the upper end of the lower mold base plate 4. The upper mold 2 has an upper mold core 21 inside, and the lower mold 3 has a lower mold core 31. A handle cavity 6 is provided between the upper mold core 21 and the lower mold core 31. The ejection mechanism 5 includes an ejector pin 51, an inclined ejector 52, a guide block 53, and a push plate 54. The push plate 54 is disposed at the upper end of the lower mold base plate 4. The guide block 53 is fixed to the bottom of the lower mold 3. The lower ends of the ejector pin 5 and the inclined ejector 52 are connected to the push plate 54. The ejector pin 5 and the inclined ejector 52 slide within the lower mold 3 and the lower mold core 31. The inclined ejector 52 passes through the guide block 53 and is symmetrically arranged in pairs towards the center.

[0015] like Figures 1-5 As shown, the working principle of this utility model is as follows: The upper mold base plate drives the upper mold to close downwards, and the upper mold core and lower mold core precisely fit together to form a sealed handle cavity, providing molding space for the molten material. At this time, the ejector mechanism is in its initial reset state, with the ejector pins and the tops of the angled ejectors fitting against the bottom of the cavity without affecting its integrity. After the injection molding machine injects the molten plastic into the cavity and completes cooling and solidification, the upper mold base plate drives the upper mold to separate upwards, realizing the mold opening action and leaving vertical space for subsequent demolding.

[0016] External driving force drives the push plate upward, and the push plate synchronously drives the ejector pins and angled ejectors to slide along the reserved channels of the lower mold and lower mold core. Among them, the ejector pins mainly provide vertical ejection force and provide uniform support to the bottom of the handle; the angled ejectors, due to their structure of passing through fixed guide blocks and being symmetrically inclined towards the center in pairs, generate precise lateral displacement with the help of the guide blocks while moving vertically. This combined vertical ejection and lateral core pulling motion can smoothly disengage from the lateral undercut or groove structure of the handle and avoid demolding interference.

[0017] By employing the inclined design of the slanted ejector and the precise guidance of the guide block, the vertical ejection force is converted into a lateral core-pulling force, solving the problem of handle-like undercut demolding that traditional ejector pins cannot handle, and avoiding defects such as product scratches and deformation. The guide block provides motion trajectory constraints for the slanted ejector, effectively preventing it from deviating, jamming, or colliding during sliding. At the same time, the synergistic effect of the ejector pin and the slanted ejector makes the ejection force distribution more balanced, reducing the risks of ejector plate tilting and asynchronous ejection.

[0018] As a further preferred embodiment, the upper mold base plate 1 is provided with a gating channel 11 that communicates with the handle cavity 6.

[0019] As a further preferred embodiment, the handle cavity 6 includes a first handle cavity 61 and a second handle cavity 62. Both the first and second handle cavities 61 and 62 are equipped with three sets of spaced ejector pins 51 and seven sets of angled ejectors 52. The seven sets of angled ejectors 52 include three sets of symmetrically arranged angled ejectors 52 and one set of rear-end angled ejectors 52. The symmetrical layout of the first and second handle cavities, combined with the gating system design within the mold base plate, allows molten plastic to enter both cavities simultaneously and in equal amounts. The three sets of spaced ejector pins provide uniform support to the key stress points at the bottom of the handle, preventing localized stress concentration. The distribution of the seven sets of angled ejectors (three sets of symmetrically arranged angled ejectors + one set of rear-end angled ejectors) is matched to the undercut position of the handle. The symmetrical angled ejectors act on the lateral undercuts on both sides of the handle, while the rear-end angled ejector addresses the groove structure at the tail of the handle, achieving full-area demolding support.

[0020] As a further preferred embodiment, the head of the angled ejector 52 is tilted outward. Since the lateral undercuts of the panel handle are mostly located on the inner wall or edge, tilting the head of the angled ejector outward allows its head to fit against the inner surface of the undercut during ejection, reducing demolding jamming or product scratches.

[0021] As a further preferred embodiment, the tilt angle of the inclined top 52 is 6 to 10 degrees. If the angle is too small, the lateral displacement will be insufficient, and it will not be able to completely disengage from the undercut; if the angle is too large, it will lead to an increase in the friction between the inclined top and the guide block and the cavity.

[0022] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
