Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a slide pre-drawing structure for injection molds. Background Art

[0002] In injection molds, when injecting some slender products with holes, since the products are slender and have a row of holes, the use of general slide demoulding after injection molding is likely to cause the product to deform. Therefore, a slide first extraction structure for injection molds is designed. Utility Model Content

[0003] The purpose of the utility model is to provide a slide-first-drawing structure for injection molds in view of the deficiencies in the prior art. The slide-first-drawing structure for injection molds has novel design, simple structure, good demoulding effect and high efficiency.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0005] A slide pre-extraction structure for an injection mold includes a slide seat, a slide is installed on the upper left end of the slide seat, and the slide is installed on the upper end of the slide seat through a slide drive block, and the upper end of the slide seat is equipped with an inclined top for driving the slide drive block, a horizontally arranged slide insert is installed in the slide, and the slide insert is installed in the slide drive block, and a plurality of product hole core pulling needles arranged in a row are provided on the right side of the slide insert.

[0006] Among them, a corresponding matching shovel is installed on the upper right side of the sliding seat.

[0007] Wherein, a wear-resistant block is installed between the shovel and the sliding seat.

[0008] Wherein, an insert avoidance hole corresponding to and matching the slide insert is provided at the upper end of the slide.

[0009] The beneficial effects of the present invention are as follows: the present invention is a structure for first pulling out a slide for an injection mold, comprising a slide seat, a slide seat being mounted on the upper left end of the slide seat, and the slide seat being mounted on the upper end of the slide seat through a slide drive block, and a slant top for driving the slide drive block being mounted on the upper end of the slide seat, a slide insert being mounted in a horizontal arrangement in the slide seat, and the slide insert being mounted in the slide drive block, and a plurality of product hole core pulling needles arranged in a row being mounted on the right side of the slide insert. When demolding, the present invention first drives the slide drive block through the slant top, and since the slide drive block is equipped with a slide insert, the slide insert first cores the product hole, and then the slide is demolded, effectively protecting the product from deformation and improving the demolding effect and performance; therefore, the present invention has the advantages of novel design, simple structure, good demolding effect and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described below with reference to the accompanying drawings. However, the embodiments in the accompanying drawings do not constitute any limitation to the present invention.

[0018] The present invention will be described below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, a slide pre-extraction structure for an injection mold includes a slide seat 1, a slide 11 is installed at the upper left end of the slide seat 1, and the slide 11 is installed at the upper end of the slide seat 1 through a slide drive block 111, and the upper end of the slide seat 1 is equipped with a slanted top 12 for driving the slide drive block 111, a horizontally arranged slide insert 13 is installed in the slide 11, and the slide insert 13 is installed in the slide drive block 111, and a plurality of product hole core pulling needles 131 arranged in a row are provided on the right side of the slide insert 13.

[0020] Furthermore, a corresponding shovel 14 is installed on the upper right side of the sliding seat 1.

[0021] Furthermore, a wear-resistant block 15 is installed between the shovel 14 and the sliding seat 1.

[0022] Furthermore, an insert avoidance hole 112 corresponding to and matching the slide insert 13 is provided at the upper end of the slide 11 .

[0023] Further explanation is needed. When demolding, the present invention first drives the slide drive block 111 through the inclined top 12. Since the slide drive block 111 is equipped with a slide insert 13, the slide insert 13 first cores the hole of the product, and then the slide is demolded, which effectively protects the product from deformation and improves the demolding effect. Therefore, the present invention has the advantages of novel design, simple structure, good demolding effect and high efficiency.

[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
