Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a demoulding mechanism of an automobile interior decoration part mold. Background Art

[0002] Automotive interior parts are an integral part of the car. After the existing molds are used to mold the automotive interior parts, it is very difficult to demould smoothly. Since the existing molds use the integral core-pulling method, the adhesion between the mold and the product is large during demoulding, so the raised parts are prone to deformation, affecting the appearance of the product, and the probability of product scrapping is high.

[0003] In view of this, it is necessary to provide a demoulding mechanism for an automobile interior decoration part mold to overcome the above-mentioned defects. Summary of the invention

[0004] The purpose of the present invention is to provide a demoulding mechanism for an automobile interior decoration part mold, which can greatly reduce the loss rate of injection molded products.

[0005] In order to achieve the above object, the technical solution provided by the present invention is implemented as follows: a demoulding mechanism for an automobile interior decoration mold, comprising:

[0006] A slider seat, wherein a slope is extended from the slider seat and an inclined slide groove is provided on the slider seat;

[0007] A shovel block, the shovel block is slidably mounted on the slider seat, and a contact interface is provided on a side of the shovel block close to the slope;

[0008] A slider ejector pin, wherein the slider ejector pin is installed on the slope of the slider seat in the horizontal direction, and the abutment interface of the shovel block can abut against one end of the slider ejector pin, and the other end of the slider ejector pin can extend out of the slider seat;

[0009] An inclined guide post, the inclined guide post is movably inserted into the inclined slide groove;

[0010] The oil cylinder is installed at the bottom of the slider seat, and the oil cylinder drives the slider seat to move in the horizontal direction.

[0011] Preferably, the inclination of the slope is consistent with the inclination of the inclined chute.

[0012] Preferably, the slope is provided with a mounting hole in the horizontal direction, and the slider ejector pin is movably inserted into the mounting hole.

[0013] Preferably, the mounting hole includes an insertion section and a limiting section connected to the insertion section, the slider ejector includes an insertion portion and a main body connected to the insertion portion, the insertion portion is inserted from the limiting section into the insertion section, and the main body is accommodated in the limiting section.

[0014] Preferably, the demoulding mechanism of the automobile interior decoration part mold further includes a mounting bracket, the oil cylinder is mounted on the top of the mounting bracket, and the mounting bracket is connected to the frame of the demoulding equipment.

[0015] Compared with the prior art, the beneficial effect lies in that the whole demoulding process is divided into two steps: the first step is preliminary demoulding, which makes the injection molded product no longer completely adhere to the rear mold, reduces the adhesion between the injection molded product and the rear mold, and reduces the adhesion between the injection molded product and the rear mold during the subsequent full demoulding, thereby preventing the injection molded product from being easily deformed during the full demoulding, and even causing the injection molded product to be scrapped due to the excessive ejection distance of the slider ejector 3 in a short time and the excessive ejection force;

[0016] The second step is complete demoulding, which makes the injection molded product no longer adhere to the back mold and completes the demoulding of the injection molded product, thus greatly reducing the loss rate of the injection molded product.

[0017] Other features and advantages of the present invention will be set forth in the following description, and part will be apparent from the description, or may be understood through the practice of the present invention. The features and advantages of the present invention may be realized and obtained through the elements and combinations specifically indicated in the appended application scope.

[0026] See also Figure 1 to Figure 2 The present invention provides a demoulding mechanism for an automobile interior decoration part mold, comprising:

[0027] A slider seat 1, wherein a slope 11 is extended from the slider seat 1, and an inclined slide groove 12 is provided on the slider seat 1;

[0028] A shovel block 2, wherein the shovel block 2 is slidably mounted on the slider seat 1, and a contact interface 21 is provided on a side of the shovel block 2 close to the slope 11;

[0029] A slider ejector pin 3, wherein the slider ejector pin 3 is installed on the slope 11 of the slider seat 1 in the horizontal direction, and the abutment interface 21 of the shovel block 2 can abut against one end of the slider ejector pin 3, and the other end of the slider ejector pin 3 can extend out of the slider seat 1;

[0030] The inclined guide column 4 is movably inserted into the inclined slide groove 12 to enable the slider seat 1 to move horizontally toward the right to extrude the shovel block 2, so that the abutment interface 21 of the slider seat 1 abuts against one end of the slider ejector pin 3, and the other end of the slider ejector pin 3 can extend out of the slider seat 1, pass through the rear mold and lift up the injection molded product on the rear mold.

[0031] After the mold is completed, the front mold of the mold will be separated from the rear mold, and the injection molded product will adhere to the rear mold. The inclined guide column 4 is movably inserted in the inclined slide groove 12 to move the slider seat 1 horizontally toward the right to extrude the shovel block 2, so that the abutment interface 21 of the slider seat 1 abuts against one end of the slider ejector pin 3. The slider ejector pin 3 extends toward the left side of the slider seat 1, passes through the rear mold and lifts up the injection molded product on the rear mold, so that the injection molded product is no longer completely adhered to the rear mold, thereby reducing the adhesion between the injection molded product and the rear mold, and preliminarily completing the demolding of the injection molded product.

[0032] It should be noted that, in this embodiment, the inclination of the slope 11 is consistent with the inclination of the inclined slide groove 12; when the shovel block 2 is placed on the slider seat 1, it can move a small distance in the horizontal direction on the slider seat 1 (the moving distance range is: 0-5mm), and the shovel block 2 and the slider seat 1 remain in an inseparable state.

[0033] In a preferred embodiment, the slope 11 is provided with a mounting hole 13 corresponding to the slider ejector pin 3 in the horizontal direction, and the slider ejector pin 3 is movably inserted and installed in the mounting hole 13 .

[0034] In a preferred embodiment, the mounting hole 13 includes an insertion section 131 and a limiting section 132 connected to the insertion section 131, the slider ejector pin 3 includes an insertion portion 31 and a main body portion 32 connected to the insertion portion 31, the insertion portion 31 is inserted into the insertion section 131 by the limiting section 132, and the main body portion 32 is accommodated in the limiting section 132.

[0035] In this way, when the inclined guide column 4 is movably inserted into the inclined slide groove 12 to move the slider seat 1 horizontally toward the right to extrude the shovel block 2, the abutment interface 21 of the slider seat 1 abuts against one end of the slider ejector pin 3, so that the insertion section 131 of the slider ejector pin 3 extends toward the left side of the slider seat 1, passes through the rear mold and lifts up the injection molded product on the rear mold.

[0036] In a preferred embodiment, the demoulding mechanism of the automobile interior decoration part mold further includes an oil cylinder 5 , which is installed at the bottom of the slider seat 1 , and is used to drive the slider seat 1 to move in a horizontal direction.

[0037] After the initial demoulding of the injection molded product, some parts of the injection molded product are still adhered to the rear mold and have not been completely demoulded. The oil cylinder 5 drives the slider seat 1 to continue to move horizontally toward the right to extrude the shovel block 2, so that the slider ejector pin 3 continues to extend out of the slider seat 1 to pass through the rear mold and completely lift up the injection molded product on the rear mold, so that the injection molded product no longer adheres to the rear mold, and the demoulding of the injection molded product is completely completed.

[0038] When the oil cylinder 5 drives the slider seat 1 to continue to move toward the right side in the horizontal direction to extrude the shovel block 2, the abutment interface 21 of the slider seat 1 abuts against one end of the slider ejector 3, and the insertion section 131 of the slider ejector 3 continues to extend toward the left side of the slider seat 1 to pass through the rear mold and lift up the injection molded product on the rear mold. At this time, the main body 32 of the slider ejector 3 abuts against the connection between the insertion section 131 and the limiting section 132 to limit the insertion section 131 of the slider ejector 3 from extending too long.

[0039] The advantage of this demoulding method is that the entire demoulding process is divided into two steps: the first step is preliminary demoulding, which makes the injection molded product no longer completely adhere to the rear mold, reducing the adhesion between the injection molded product and the rear mold, and reducing the adhesion between the injection molded product and the rear mold during the subsequent full demoulding, so as to avoid the injection molded product from being easily deformed during full demoulding, and even the injection molded product may be scrapped due to the excessive ejection distance of the slider ejector 3 in a short time and the excessive ejection force;

[0040] The second step is complete demoulding, which makes the injection molded product no longer adhere to the back mold and completes the demoulding of the injection molded product, thus greatly reducing the loss rate of the injection molded product.

[0041] In a preferred embodiment, the demoulding mechanism of the automotive interior part mold further includes a mounting bracket 6, the oil cylinder 5 is mounted on the top of the mounting bracket 6, and the mounting bracket 6 is connected to the frame of the demoulding device. In this way, by providing the mounting bracket 6, the oil cylinder 5 is easily installed.

[0042] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
