Description

Technical Field

[0001] The utility model relates to the field of core-pulling moulds, in particular to a core-pulling mould structure with front-end clamping claws of an instrument panel. Background Art

[0002] Due to the limited assembly space, the claw structure of the dashboard body is clamped with the crossbeam in the whole vehicle state, forming an inclined angle. There are some undercuts in the claw structure of the dashboard body that cannot be demolded normally, resulting in the problem that the mold cannot be made normally. In addition, under normal circumstances, the front claw mold structure of the dashboard is first cored and then ejected. Because the oil cylinder used for core pulling first takes up too much space, the mold B plate is not strong enough to be dug out, which affects the life of the mold. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a dashboard front end claw core-pulling mold structure, which can solve the problem that the claws cannot be normally removed from the mold due to undercuts, thereby ensuring the product function and mold production efficiency.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] An embodiment of the utility model provides a core-pulling mold structure for a front-end claw of an instrument panel, comprising a top block, in which an inclined core-pulling mechanism is provided, one side of the core-pulling mechanism is connected to a spring, and the other side is provided with a limit block. The core-pulling mechanism can move a set stroke in a direction away from the undercut of the claw under the action of the spring force so as to be limited by the limit block.

[0006] As a further implementation, the angle between the moving direction of the core pulling mechanism and the ejecting direction of the ejector block is an acute angle.

[0007] As a further implementation, the angle is no greater than 30°.

[0008] As a further implementation, the spring has the same inclination angle as the core pulling mechanism.

[0009] As a further implementation, a receiving cavity for installing a spring is provided in the top block.

[0010] As a further implementation, the core-pulling mechanism is provided with a protrusion on one side corresponding to the limit block, and the limit block has a hook matched with the protrusion.

[0011] As a further implementation, the limit block is installed at the bottom of the top block.

[0012] As a further implementation, the stroke of the core pulling mechanism is greater than or equal to the undercut depth of the claws.

[0013] As a further implementation, push rods are symmetrically provided on both sides of the core-pulling mechanism, and the push rods are used to push the top block to move vertically.

[0014] As a further implementation, a guide groove for the movement of the core pulling mechanism is provided in the top block.

[0015] The beneficial effects of the utility model are as follows:

[0016] (1) The utility model arranges an inclined core-pulling mechanism inside the ejector block, the core-pulling mechanism is connected to a spring, and a limit block is arranged on one side of the core-pulling mechanism. During the ejection movement of the ejector block, the core-pulling mechanism moves a certain distance under the action of the spring force and then limits itself, disengages from the clamping claw and then ejects the clamping claw together with the ejector block, thereby solving the problem that the clamping claw cannot be ejected normally due to the undercut. The mold structure is optimized by adding a straight ejector to the inclined ejector, so that the product size requirements are met and normal production can be achieved.

[0017] (2) The running trajectory of the core pulling mechanism of the utility model forms an angle of no more than 30° with the ejection trajectory of the ejector block, and the running trajectory is greater than or equal to the undercut depth of the clamping claw, further ensuring that the core pulling mechanism is completely detached from the undercut of the clamping claw.

[0026] Embodiment 1:

[0027] In a typical embodiment of the present invention, Figure 1-Figure 4 As shown, a core-pulling mold structure for the front end claws of an instrument panel is provided.

[0028] Since the claw structure of the dashboard body forms an inclined angle with the crossbeam clamp in the whole vehicle state, there are some undercuts in the claw structure of the dashboard body that cannot be ejected normally. Based on this, the present embodiment provides a core-pulling mold structure for the claw at the front end of the dashboard, which optimizes the mold structure by adding a straight top in the inclined top, so that the undercut of the claw can be ejected smoothly.

[0029] The above mold structure is described in detail below with reference to the accompanying drawings.

[0030] The mold structure of this embodiment includes a top block 2, a core pulling mechanism 4, a limit block 6, etc. The top block 2 is connected to two vertically arranged top rods 3, and the top block 2 can be lifted up by the top rods 3; Figure 6 As shown, the ejection direction of the ejection block 2 is vertically upward.

[0031] A guide groove is provided in the top block 2, and the core pulling mechanism 4 is obliquely installed in the guide groove inside the top block 2. The movement direction of the core pulling mechanism 4 forms a certain angle with the ejection direction of the top block 2, and the angle is an acute angle. The core pulling mechanism 4 has a certain stroke, forming a movement track of a certain length, which is defined as L. The angle between the running track of the core pulling mechanism 4 and the ejection track of the top block 2 is a, a≤30°, because if the angle a is too large, it is easy to fail, resulting in product scrapping.

[0032] like Figure 5 As shown, the depth of the claw undercut 8 is L1, and the thickness of the inner protrusion of the claw undercut 8 is M1; Figure 6 As shown, the vertical distance between the end of the motion track of the core pulling mechanism 4 and the end of the ejection track of the ejector block 2 is M. In this embodiment, L and M meet the following conditions:

[0033] L≥L1, M≥M1 (completely out of the product) + 2mm (safety margin);

[0034] When the above conditions are met, the clamping claw undercut 8 can be demoulded normally.

[0035] It should be noted that the core-pulling mechanism 4 of this embodiment adopts the existing technology, so its specific structure will not be described in detail here.

[0036] In this embodiment, the side where the core pulling mechanism 4 and the claw 1 cooperate is the rear side, and the other side is the front side; Figure 2-Figure 4 As shown, a spring 5 is connected to the front bottom side of the core pulling mechanism 4, a receiving cavity is provided in the top block 2, the spring 5 is arranged in the receiving cavity and is connected to the inside of the top block 2; the spring 5 is also arranged at an angle, and its inclination angle is consistent with that of the core pulling mechanism 4.

[0037] A limiting block 6 is installed at the bottom position of the rear mold of the top block 2, and the limiting block 6 has a hook 7 on the side facing the core pulling mechanism 4; a protrusion 9 is provided at the rear part of the core pulling mechanism 4 near the bottom end, and the protrusion 9 can cooperate with the hook 7 of the limiting block 6; when the running stroke of the core pulling mechanism 4 reaches L, the protrusion 9 fits with the hook 7 to form a limiting effect; by setting the hook 7, the spring 5 can be prevented from failing.

[0038] In this embodiment, the core pulling mechanism 4 is limited to a certain stroke by the hook 7, the guide groove and the spring 5. After the core pulling mechanism 4 is completely separated from the claw undercut 8, the ejector block 2 drives the core pulling mechanism 4 to eject the claw 1. The mold structure is optimized by adding a straight ejector to the inclined ejector to meet the product size requirements and enable normal production.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
