Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a striker reset structure for an inclined top in a slide block. Background Art

[0002] Some injection molding products involve side push slider assisted molding. The products on both sides of the side push slider are also provided with holes or undercut structures 01 perpendicular to the exit direction, such as Figure 1 As shown, a structure that requires a slider or a slanted top is required. If it is designed according to a conventional structure, the structure will be complicated and the processing cycle and cost will be very high.

[0003] Conventional tilt top reset uses springs, such as Figure 2 and Figure 3 As shown, the opening and closing sequence is: the front and rear molds are opened normally, the slider A retreats and compresses the spring, the inclined top seat B remains stationary under the positioning of the positioning bead D, and the two inclined tops are retracted and released; when the slider A completes the stroke C, it drives the inclined top seat B to retreat together to complete the slider core pulling; when the mold is closed, the inclined top and the slider move forward at the same time. When A completes the stroke C and fits with B, the undercut of the inclined top has been detached, but when AB is fitted and retreats together, B exceeds the positioning of D. Due to the reaction force of the spring compression, B is instantly pushed back to reset, causing the inclined top to move outward again, thereby pulling the product. Product defects such as product burrs, pulling, and scraping glue are caused by the unsmooth inclined top mechanism in the slider.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a striker reset structure for the inclined top in the slider. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a striker reset structure for the inclined top in the slider, which avoids the product problems caused by the instantaneous reset of the inclined top base by the spring compression when the mold is opened. The reset striker can more stably ensure that the inclined top returns to its position when the mold is closed.

[0006] The cam is provided with a bottom plate, and a positioning bead for positioning the cam seat is installed on the bottom plate. The positioning bead is used to position the cam seat, and a reset pin is installed on the cam seat. The reset pin passes through the side molding slider and points to the mold core of the product molding.

[0007] Preferably, there are two inclined roofs.

[0008] Preferably, the diameter of the reset striker is ≥φ6.0 mm, and the head of the reset striker abuts against the mold core when the mold is closed.

[0009] Preferably, the side-molding slider is provided with an inclined slide groove cooperating with the inclined top, and the inclined top seat is provided with a dovetail slide groove cooperating with the tail of the inclined top, the direction of the dovetail slide groove is horizontal and perpendicular to the backward direction, and the tail of the inclined top is slidably clamped in the dovetail slide groove.

[0010] Preferably, the positioning bead is elastically mounted on the male mold core below the bottom plate in the vertical direction by a spring, the top cross-section of the positioning bead is conical, and a positioning hole cooperating with the positioning bead is provided on the bottom surface of the inclined top seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When opening the mold, the reset striker and the slider are slidably matched, and no resistance is generated, ensuring that the inclined top seat is positioned and immovable;

[0013] 2. The diameter of the reset striker should be ≥φ6.0 to provide sufficient support;

[0014] 3. The length of the striker can be processed by a grinder to ensure accuracy, and it is also easy to adjust, which can ensure that the relative distance between the inclined top seat and the mold core remains unchanged. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A striker reset structure for an inclined top in a slider, the striker reset structure for an inclined top in a slider comprises a side-molded slider 1, a slider seat 2, an inclined guide column 3, a shovel base 4, an inclined top seat 5, an inclined top 6, a bottom plate 7, a positioning bead 8 and a reset striker 9, the side-molded slider 1 is installed on the slider seat 2, the slider seat 2 is provided with an inclined guide column 3 that drives it to move, the outer end of the slider seat 2 is fixed with a shovel base 4, the upper end of the slider seat 2 is provided with an avoidance groove, the avoidance groove is slidably provided with an inclined top seat 5, the inclined top seat 5 is horizontally A slidable inclined top 6 is inserted into the side, and the number of the inclined top 6 is generally two, which is determined according to the number of holes or undercut molding structures on the product. The inclined top 6 passes through the side molding slider 1, and the inclined top 6 protrudes outward through the side end of the side molding slider 1 and is provided with a hole or undercut molding protrusion 60. A bottom plate 7 is provided under the slider seat 2, and a positioning bead 8 for positioning the inclined top seat 5 is installed on the bottom plate 7. A reset pin 9 is installed on the inclined top seat 5, and the reset pin 9 passes through the side molding slider 1 and points to the mold core for product molding.

[0029] The diameter of the reset striker 9 is ≥φ6.0mm to ensure sufficient support. When the mold is closed, the head of the reset striker 9 abuts against the mold core.

[0030] The side-molding slider 1 is provided with an inclined slide groove 10 cooperating with the inclined top 6, and the inclined top seat 5 is provided with a dovetail slide groove 50 cooperating with the tail of the inclined top 6. The direction of the dovetail slide groove 50 is horizontal and perpendicular to the backward direction, and the tail of the inclined top 6 is slidably mounted in the dovetail slide groove 50. If the relative distance between the side-molding slider 1 and the inclined top seat 5 becomes smaller, the inclined top 6 will shrink inward under the restriction of the inclined slide groove 10 and the dovetail slide groove 50, and the inclined top 6 will be away from the hole or undercut structure 01.

[0031] The positioning bead 8 is elastically mounted on the male mold core below the bottom plate 7 in the vertical direction by a spring. The top cross-section of the positioning bead 8 is conical, and a positioning hole matching the positioning bead 8 is provided on the bottom surface of the inclined top seat 5.

[0032] The utility model discloses a striker reset structure for the inclined top of a slider. When the mold is opened, the inclined top seat 5 remains stationary under the action of the positioning bead 8, the slider seat 2 retreats under the drive of the inclined guide column 3, and the slider seat 2 synchronously drives the side molding slider 1 to retreat. Figure 7 As shown, the relative distance between the inclined top seat 5 and the side molding slide block 1 is reduced, and the inclined top 6 is retracted and released under the guidance of the inclined slide groove 10 and the dovetail slide groove 50, as shown in FIG. Figure 8 As shown, the side molding slide block 1 continues to retreat to fit the inclined top seat 5 and drive it to retreat together (the positioning bead 8 is pushed down), and the mold opening is completed at this time, as shown in FIG. Fig. 9 As shown;

[0033] When closing the mold: the slider seat 2 moves forward under the drive of the inclined guide pillar 3, and the slider seat 2 drives the side molding slider 1 and the inclined top seat 5 to move forward together until the reset striker 9 hits the mold core, and the inclined top seat 5 stops moving and is bounced up and positioned by the positioning bead 8 until the side molding slider 1 continues to move forward until it fits the mold core. Fig.10 As shown, the mold closing action is completed.
