Description

Technical Field

[0001] The utility model relates to the technical field of mold demoulding, in particular to an inclined ejector mechanism driven by an oil cylinder to drive a slider. Background Art

[0002] The inclined ejector mechanism is a commonly used mechanism in the design of injection molds, mainly used to solve the problem of difficult demoulding of products in the mold due to the existence of undercuts, grooves or other structures that cannot be directly demoulded from the main parting surface of the mold. The inclined ejector mechanism makes these difficult-to-demould parts smoothly separate from the mold when the product is demoulded by an inclined manner.

[0003] To solve the problem of difficult demoulding of undercuts and grooves, an inclined ejector mechanism driven by an oil cylinder to drive a slider is needed for demoulding. For example, the Chinese patent publication number "CN210679339U" in the prior art discloses an inclined ejector mechanism, including: an inclined ejector rod; an inclined ejector sleeve, a slot is opened in the inclined ejector sleeve, and one end of the inclined ejector rod is inserted into the slot; a guide slide plate, which is movably hinged to opposite sides of the inclined ejector sleeve; and an inclined ejector seat, a chute is opened in the inclined ejector seat, the inclined ejector sleeve and the guide slide plate are arranged in the chute, and the guide slide plate cooperates with the chute for guiding and sliding. The inclined ejector mechanism provided by the utility model has good guiding and sliding performance and good reliability.

[0004] Some inclined ejector mechanisms demould the products in the mold through the inclined ejector rod. However, in specific operations, similar inclined ejector mechanisms can only drive one inclined ejector rod for demoulding operations, resulting in low demoulding efficiency of the products, and there is no detailed description of how to heat and cool the products, so the practicability is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages of low demoulding efficiency of the products in the prior art, and to propose an inclined ejector mechanism driven by an oil cylinder to drive a slider.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A mold seat is fixedly connected to the side surface of the movable seat, and a temperature control component for controlling the temperature inside the mold seat is arranged inside.

[0008] Wherein, the movable seat further includes an inclined ejector component for cooperating with the mold seat for demoulding.

[0009] Furthermore, a hydraulic cylinder is fixedly installed inside the cylinder seat, an output end of the hydraulic cylinder is fixedly connected with a connecting piece, a through groove is opened on the side surface of the movable seat, and the connecting piece is inserted into the through groove.

[0010] Further, the temperature control component includes connecting rods fixedly connected to both sides of the oil cylinder seat. One end of each connecting rod extends into the movable seat and is slidably connected to a medium pipeline. The other ends of a pair of the medium pipelines are connected and communicated through a branch pipeline, and the other end of the branch pipeline extends into the mold seat.

[0011] Further, the lifter component includes lifter rods. A pair of guide grooves are formed in the end face of the movable seat. A guiding part slidably connected to the guide grooves is fixedly installed in the lifter seat. A pair of the lifter rods are slidably connected in a limiting groove formed in the side face of the guiding part.

[0012] Further, a pair of receiving grooves are provided on the side face of the movable seat. A V-shaped structure is formed between the pair of receiving grooves, and both sides thereof are respectively communicated with the guide grooves and the mold seat. The lifter rods are slidably connected to the mold seat through the receiving grooves and can abut against a product located in the mold seat.

[0013] Further, a pair of limit switches are fixedly installed on one side of the top of the lifter seat. A pressing rod is fixedly installed on the top of the movable seat. The end of the pressing rod is located between the pair of limit switches and can abut against the limit switches.

[0014] For the oil cylinder-driven slider and lifter mechanism proposed by the present utility model, the beneficial effects are as follows: The present utility model can drive a pair of lifter rods to demold a product through a hydraulic cylinder.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-5 , an inclined roof mechanism driven by an oil cylinder to drive a slider, including an inclined roof seat 1, a side surface of the inclined roof seat 1 is fixedly installed with an oil cylinder seat 2, and an inner part thereof is slidably connected with a movable seat 3.

[0024] Furthermore, a hydraulic cylinder 21 is fixedly installed inside the oil cylinder seat 2, an output end of the hydraulic cylinder 21 is fixedly connected with a connecting piece 22, a through groove 31 is formed on a side surface of the movable seat 3, and the connecting piece 22 is inserted into the through groove 31.

[0025] Still further, the temperature control component 5 includes connecting rods 51 fixedly connected to two sides of the oil cylinder seat 2. One end of the connecting rod 51 extends into the movable seat 3 and is slidably connected with a medium pipeline 52. The other ends of a pair of the medium pipelines 52 are communicated through a branch pipeline 53, and the other end of the branch pipeline 53 extends into the mold seat 4.

[0026] It should be added that the medium pipeline 52 forms an integral body with the movable seat 3 and the mold seat 4 through the branch pipeline 53. The movable seat 3 is driven by the hydraulic cylinder 21 to move. Then, the way that the medium pipeline 52 is slidably connected with the connecting rod 51 can avoid jamming.

[0027] Among them, the other end of the medium pipeline 52 is connected with a medium control system for providing heating water and cooling water for the mold seat 4, and the branch pipeline 53 is arranged inside the mold seat 4 and on both sides of the inclined roof rod 61.

[0028] More specifically, the lifter assembly 6 includes a lifter rod 61. A pair of guide grooves 62 are formed on the end face of the movable seat 3. A guide portion 63 slidably connected to the guide grooves 62 is fixedly installed in the lifter seat 1. A limiting groove 64 is formed on the side face of the guide portion 63, and a pair of the lifter rods 61 are slidably connected in the limiting groove 64.

[0029] It should be noted that when the movable seat 3 moves, a pair of the lifter rods 61 move relative to the movable seat 3, and then the lifter rods 61 are used to demold the product in the mold base 4.

[0030] Generally speaking, a pair of receiving grooves 65 are provided on the side face of the movable seat 3. A V-shaped structure is formed between the pair of receiving grooves 65, and both sides thereof are respectively communicated with the guide grooves 62 and the mold base 4. The lifter rods 61 are slidably connected to the mold base 4 through the receiving grooves 65, and can abut against the product located in the mold base 4.

[0031] It is worth mentioning that an included angle is formed at one end of a pair of the lifter rods 61 close to the mold base 4. When the movable seat 3 moves, the receiving grooves 65 are used to abut against the lifter rods 61, so that one end of the lifter rods 61 close to the included angle abuts against the product and demolds the product.

[0036] After the product is injection molded, the hydraulic cylinder 21 drives the movable seat 3 to move backward. When the movable seat 3 moves, it drives the mold base 4 to move. At this time, the lifter rods 61 are affected by the abutment of the receiving grooves 65 and move in the guide grooves 62. And because of the movement of the movable seat 3, the lifter rods 61 move relative to the movable seat 3 and then demold the product in the mold base 4.
