Improved structure of front mold pitched roof

Abstract

The utility model relates to an improved structure of a front mold pitched roof. A common front mold inclined ejector structure needs to be additionally provided with an ejector pin plate to demold a front mold inverted buckle structure, but the product thickness and the occupied space are increased, the mold cost is increased, and the mold design cost is high. The inclined ejection mechanism comprises a product arranged in a fixed mold core and a movable mold core, and is characterized by further comprising an inclined ejection assembly arranged on the fixed mold core, a spring is arranged in the inclined ejection assembly, and after the product is driven by the movable mold core to be separated from the fixed mold core by a certain distance, the inclined ejection assembly is ejected upwards under the power of the spring. A limiting drag hook is further arranged on the side portion of the pitched roof assembly, and when the pitched roof is ejected upwards, the pitched roof is limited by the drag hook to move towards the core pulling direction by a certain distance. The problem that the pitched roof is difficult to disassemble and assemble can be solved, and the mold cost is reduced.

Description

Technical Field

[0001] This utility model relates to the improvement of demolding structure, and in particular to an improved structure of the front mold angled ejector. Background Technology

[0002] A typical front mold angled ejector structure, such as Figure 1 This includes a fixed mold core, with an inclined ejector inside. The front mold ejector plate is located at the end of the inclined ejector. This type of front mold inclined ejector structure requires the addition of an ejector plate to demold the undercut structure of the front mold. However, this increases the product thickness and space occupied, increases the mold cost, and results in high mold design costs. Furthermore, the inclined ejector structure is not easy to disassemble and assemble, which increases subsequent maintenance costs. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model proposes an improved front mold angled ejector structure, which can solve the problem of difficult assembly and disassembly of the angled ejector and reduce mold costs.

[0004] Therefore, the technical solution adopted by this utility model is: an improved front mold inclined ejector structure, including a product disposed in a fixed mold core and a moving mold core, characterized in that it also includes an inclined ejector assembly disposed on the fixed mold core, wherein a spring is disposed in the inclined ejector assembly, and after the product is driven away from the fixed mold core by the moving mold core by a certain distance, the inclined ejector assembly is pushed upward by the spring force, and a limiting hook is also disposed on the side of the inclined ejector assembly, wherein when the inclined ejector is pushed upward, it is restricted by the hook to move a certain distance in the core pulling direction.

[0005] Preferably, the inclined jack assembly includes an inclined jack rod, the side of which is connected to a first inclined jack block, a return spring is provided inside the first inclined jack block, and a second inclined jack block is provided on the side of the first inclined jack block.

[0006] Preferably, a slot is provided on the lower outer side of the first inclined top block, and the pull hook is provided in the slot and installed on the moving mold core.

[0007] Preferably, an insert is provided at the bottom of the inclined rod.

[0008] Preferably, a slider is provided on the outer side of the moving mold core below the pull hook.

[0009] Preferably, an inclined pressure block is provided at the top of the inclined push rod.

[0010] This invention eliminates the front mold ejector plate. The angled ejector uses a spring-loaded ejection mechanism. The fixed mold core has an insert at the ejector block, allowing direct removal of the angled ejector from the front. A hook is installed on the moving mold core as a hard limit for the angled ejector. Under the combined action of the spring and the hook, the angled ejector can move in the reverse demolding direction for smooth demolding. This invention simplifies the mold assembly process, saves mold costs, and reduces subsequent maintenance costs. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 2-5 An improved front mold angled ejector structure is shown, comprising a product 1 disposed within a fixed mold core 2 and a moving mold core 11. The characteristic feature is that it further includes an angled ejector assembly disposed on the fixed mold core 2. A spring 6 is disposed within the angled ejector assembly. After the product is driven away from the fixed mold core 2 by the moving mold core 11 to a certain distance, the angled ejector assembly is pushed upwards by the spring 6. A limiting hook 9 is also disposed on the side of the angled ejector assembly. When the angled ejector assembly is pushed upwards, it is restricted by the hook 9 to move a certain distance in the core-pulling direction.

[0020] Specifically, the inclined top assembly includes an inclined top rod 3, the side of which is connected to a first inclined top block 7, a return spring 6 is provided inside the first inclined top block 7, and a second inclined top block 8 is provided on the side of the first inclined top block 7.

[0021] Specifically, a slot is provided on the lower outer side of the first inclined top block, and the pull hook 9 is provided in the slot. The pull hook 9 is installed on the moving mold core 11.

[0022] Specifically, an insert 4 is provided at the bottom of the inclined rod 3.

[0023] Specifically, a slider 10 is provided on the outer side of the moving mold core 11 below the pull hook 9.

[0024] Specifically, an inclined pressure block 5 is installed at the top of the inclined rod 3.

[0025] This invention considers a spring-loaded ejector mechanism for the inclined ejector, while maintaining the existing spatial position of the molded product. The inclined ejector is fitted with an insert, which needs to be enlarged to the parting line to ensure smooth repositioning during mold closing. The insert is removable from the front mold at the inclined ejector location for easy disassembly and maintenance. A tunnel-type slider is installed in the rear mold, and a hook is mounted on the moving mold core as a hard limit for the inclined ejector, protecting the mold.

[0026] The ejection process is as follows: the product first separates from the front mold core by 35mm, the angled ejector moves upward by 35mm due to the influence of the spring, and at the same time, the angled ejector moves 3mm along the core-pulling direction due to the restriction of the pull hook. After that, the front mold structure no longer contacts the product, the mold opens normally, and the product is successfully demolded with the front mold angled product undercut.

[0027] This invention eliminates the front mold ejector plate. The angled ejector uses a spring-loaded ejection method. The front mold core has an insert at the ejector block, allowing direct removal of the angled ejector from the front. A pull hook is installed on the moving mold core as a hard limit for the angled ejector. Under the combined action of the spring and the pull hook, the angled ejector can move in the reverse demolding direction for smooth demolding.

[0028] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
