Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an inclined ejector structure for solving the problem of insufficient undercut space of small products. Background Art

[0002] In the current manufacturing industry, many single products need to be made into hooks / slots for assembly to achieve their functionality. Some hooks / slots need to be made into inclined top structures on the mold, but some cannot be made into inclined top structures due to insufficient space. Some hooks / slots 01 are located inside the product cavity, such as Figure 1 As shown, the customer needs to modify the product.

[0003] Figure 2 It is a conventional slanted top style. The space required for the conventional slanted top is relatively large, and it is not suitable for undercut demolding in a narrow space. The space of the product is very small, and the conventional slanted top cannot be demolded at all. Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a slanted top entry structure that solves the problem of insufficient undercut space for small products. Utility Model Content

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an inclined top insertion structure for solving the problem of insufficient undercut space for small products, the inclined top insertion structure for solving the problem of insufficient undercut space for small products includes a male mold core, an inclined top, an insert and a bobbin, the male mold core is provided with a product molding cavity, the male mold core is obliquely inserted with two inclined tops in the vertical direction, and the outside of the inclined tops is provided with undercut bosses for product hook / slot molding, the male mold core is vertically inserted with an insert that can be demolded together with the product, the insert includes an insertion end inserted into the male mold core and a molding part, the inclined top is abutted against the molding part, the inclined top and the head are used for product inner cavity molding, and a bobbin for positioning the insert is installed in the male mold core.

[0006] Preferably, the male mold core is provided with two figure-eight shaped inclined top sliding grooves, and the inclined tops are slidably inserted in the inclined top sliding grooves.

[0007] Preferably, the sloping top is designed to be thinned.

[0008] Preferably, the inclined top is made of UNIMAX die steel.

[0009] Preferably, a through slot for inserting the bobbin is horizontally provided on the male mold core, and a groove matching with the bobbin head is provided at the insertion end of the insert, and the bobbin is inserted into the groove along the through slot.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The inclined ejector and the head are used for product inner cavity molding. By adding inserts, the size of the inclined ejector head is greatly shortened to avoid interference between the two inclined ejectors.

[0012] When the insert is embedded in the mold, it is necessary to add a wave positioning to prevent the insert from falling out of the mold;

[0013] The material of the inclined roof needs to be selected with good toughness to improve the strength of the inclined roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] See also Figures 3 to 9 , the utility model embodiment includes:

[0026] A slanted top insert structure for solving the problem of insufficient undercut space for small products, the slanted top insert structure for solving the problem of insufficient undercut space for small products comprises a male mold core 1, a slanted top 2, an insert 3 and a bobbin 4; the male mold core 1 is provided with a product molding cavity, the male mold core 1 is obliquely inserted with two slanted tops 2 in the vertical direction, the outside of the slanted top 2 is provided with an undercut boss 20 for molding a product hook / slot 01, the male mold core 1 is vertically inserted with an insert 3 that can be demoulded together with the product, the insert 3 comprises an insertion end 31 inserted into the male mold core 1 and a molding portion 32, the slanted top 2 is abutted against the molding portion 32, the slanted top 2 and the head 32 are used for molding the inner cavity of the product, the size of the head of the slanted top 2 is shortened by burying the insert 3, and interference between the two slanted tops 2 is avoided, and a bobbin 4 for positioning the insert 3 is installed in the male mold core 1 to prevent the insert 3 from falling out of the mold.

[0027] The male mold core 1 is provided with two figure-eight inclined top slide grooves 10, in which the inclined top slide grooves 10 are slidably inserted. When the mold is closed, the head distance of the inclined top 2 is consistent with the inner cavity of the product. When the mold is opened, the inclined top 2 is ejected along the inclined top slide groove 10. Since the inclined top slide groove 10 is in the figure-eight shape, the head distance of the inclined top 2 is gradually reduced, and the undercut boss 20 is separated from the product undercut.

[0028] The inclined top 2 is designed to be thinned and made of a material with good toughness, UNIMAX mold steel, to improve the strength of the inclined top.

[0029] The male mold core 1 is horizontally provided with a through slot 11 for inserting the ball 4, and the insertion end 31 of the insert 3 is provided with a groove 310 that matches the head of the ball 4. The ball 4 is inserted into the groove 310 along the through slot 11 to clamp the insert 3 so that the insert 3 will not fall out of the mold.

[0030] The utility model solves the problem of insufficient undercut space for small products when the inclined top insertion structure is working. Figure 6 In the un-ejected state, Figure 7 The inclined ejector 2 is ejected, driving the insert 3 and the product 00 to be ejected forward together. At this time, the undercut boss 20 of the inclined ejector 2 is separated from the hook / slot 01 of the product, but the insert 3 is still in the product 00. The robot takes the insert 3 and the product 00 out of the mold together, and takes the insert 3 out of the product 00. Figure 8 As shown, Fig. 9 To put the insert 3 into the mold and continue molding.

[0031] The utility model discloses an inclined ejector insert structure which solves the problem of insufficient undercut space of small products. The thickness of the inclined ejector is reduced and the insert is buried, thereby shortening the size of the head of the inclined ejector and avoiding interference between two inclined ejectors.
