Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the utility model discloses an inside pouring mould that advances of slider to one side, including die block 1, die core 11, oblique guide pillar 31, take-up housing 3, be fixed in oblique slider 32 on the take-up housing 3, public template 2, die core 21, runner 4 and set gradually thimble board A5, thimble board B6 on the public template 2 bottom surface, thimble board A5 passes through screw fixed connection with thimble board B6. The cavity 11 is located in the cavity plate 1, the core 21 is located in the core plate 2, the cavity 11 and the core 21 are arranged opposite to each other and form a cavity for product molding, and the flow passage 4 is located in the cavity. One end of the inclined guide post 31 is fixed on the female die plate 1, the other end of the inclined guide post penetrates through the sliding block seat 3, the sliding block seat 3 is located on the male die plate 2, and the inclined sliding block 32 is fixed on the sliding block seat 3. The inclined slider 32 is further fixed with balls 33 (shown in fig. 6) and the runner insert 7, and the runner insert 7 is fixed to the inclined slider 32 via the balls 33. A runner thimble 8 is fixed on the top surface of the thimble plate a5, and one end of the runner thimble 8 far away from the thimble plate a5 is positioned right below the runner insert 7 when the mould is opened and ejected. The straight line of the runner insert pin 7 and the straight line of the runner thimble 8 are parallel to each other, and the distance between the runner insert pin 7 and the runner thimble 8 in the mold closing state is equal to the movement stroke of the inclined slide block 32. In the mold closing state, the straight line of the runner insert pin 7 and the straight line of the runner ejector pin 8 are parallel to each other but do not coincide with each other.

Referring to fig. 2 and 3, the flow channel insert needle 7 includes a cylindrical flow channel insert needle bar 71 and a flow channel insert needle hanging table 72 integrally formed with the flow channel insert needle bar 71, a clamping groove 81 for clamping the flow channel insert needle hanging table 72 and the flow channel insert needle bar 71 is formed at a top end of the flow channel insert needle 8, and a cross section of the clamping groove 81 is in an inverted T shape. The circumferential side of the runner insert needle bar 71 near one end of the runner insert needle hanging table 72 is provided with a concave annular groove 73. An inclined downward guide surface 82 is arranged on the inner bottom wall of the clamping groove 81, and an included angle between the guide surface 82 and the horizontal direction is 21.8 degrees. The guide surface 82 makes it easier for the runner insert 7 to be clamped into the clamping groove 81 of the runner thimble 8, so as to facilitate the runner thimble 8 to lift the runner insert 7 upwards in the later period.

Referring to fig. 4 and 5, a convex ring position buckle 9 with a triangular cross section is disposed on the top surface of the slider seat 3, and a sliding groove 91 engaged with the ring position buckle 9 is disposed on the bottom surface of the inclined slider 32. The runner insert needle 7 moves to the position of the ring position buckle 9 along with the inclined slide block 32, and the slide groove 91 on the bottom surface of the inclined slide block 32 is in clamping and embedding fit with the ring position buckle 9, so that the inclined slide block 32 is prevented from falling under the action of force. The runner insert 7 moves to the position of the ring position buckle 9 along with the inclined slide block 32, and the runner insert 7 is clamped in the clamping groove 81 of the runner thimble 8.

The implementation principle of the embodiment is as follows: when the mold is opened, the female mold plate 1 rises to be separated from the male mold plate 2, the female mold plate 1 rises to drive the inclined guide post 31 to rise, and in the moving process of the inclined guide post 31, the inclined slide block 32 and the runner insert pin 7 slide outwards on the male mold plate 2 together until the runner insert pin 7 is inserted into the clamping groove 81 at the top end of the runner ejector pin 8;

the injection molding machine ejects the ejector plate B6 and the ejector plate A5 together, and the runner ejector 8 is fixed on the ejector plate A5, and the ejector plate A5 ejects the runner ejector 8 and the runner insert 7 upwards, so that the runner 4 is ejected and separated from the male mold core 21, the mold opening stroke of the mold is reduced, more machine table requirements are met, the length of the runner is shortened, and the mold cost is reduced.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
