Abstract
The utility model relates to a mechanical disassembling tool and discloses a linear type drawing device which comprises a locking head. The utility model is characterized in that the linear type drawing device also comprises a mandrel, a handle and a stop block, wherein the locking head is arranged at the front end of the mandrel; the handle capable of sliding back and forth is arranged on the mandrel; the stop block capable of stopping the movement of the handle is arranged at the rear end of the mandrel; and the handle is in a cylinder which is thick at two ends and thin in the middle. The linear type drawing device solves the problems of time and labor wasting, hand pain and poor safety and reliability in the prior art when a U-shaped disassembling tool is adopted for disassembling a valve needle. With the adoption of the linear type drawing device, the valve needle is easily drawn out from the linear type drawing device, the disassembling efficiency is improved, and the time is saved, the operator does not need to draw with all strength, the hand feels no pain due to violent squeezing, and the scratching and the cutting of the hand are avoided.
Description
Technical field
The utility model relates to a kind of mechanical extracting tool, particularly relates to a kind of linear pattern draw-off gear of dismantling needle.
Background technology
Needle is very important parts in injection mold, and its quality is directly connected to the effect of injection mo(u)lding, so need often needle to be taken apart from injection mold to carry out mainteinance repair.As shown in Figure 1, dismantle needle now and adopt U font extracting tool more, comprise U type frame, pass a mandrel, be provided with locking head at the front end of mandrel from the middle part of U type frame.During the dismounting needle, operating personnel at first utilize locking head that the locking of needle rear end is blocked, then forefinger is extend in the neutral gear between mandrel and U type frame one side, and middle finger extend in the neutral gear between mandrel and another side of U type frame, again thumb is propped up core back-end, exert all one's strength laterally at last needle is pulled out, adopt this kind dismounting mode, be to pull out needle, waste time and energy, operating personnel's strength is had relatively high expectations with stiffness of hand in children.The pain that simultaneously hand also can be extruded in drawing process, and pull out handle with strength and also have the danger that is scratched incised wound, security reliability is relatively poor.
The utility model content
Waste time and energy in order to solve available technology adopting U font extracting tool dismounting needle, cause the hand pain easily, the problem that security reliability is relatively poor, the utility model provides a kind of can be easy to needle to extract the linear pattern draw-off gear.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of linear pattern draw-off gear, comprise locking head, it is characterized in that: also comprise mandrel, handle, block, be provided with locking head at the front end of mandrel, mandrel be provided with can before and after the handle that slides, be provided with the block that can stop that handle moves in the rear end of mandrel.
Aforesaid linear pattern draw-off gear is characterized in that: described handle is a cylindrical column, and described cylindrical column two ends are thick, and is middle thin.
The beneficial effects of the utility model are: the utility model linear pattern draw-off gear, and simple in structure, easy to use, safe and reliable.Operating personnel hold handle and exert oneself backward, the block of handle rear end bump core back-end, locking head of every bump can drive needle and move laterally, bump back needle for several times just is pulled out easily, improved removal efficiency, saved the time, operating personnel's drawing needle does not need to use too great strength simultaneously, hand just can or not cause the scuffing and the incised wound of hand owing to pain is felt in violent extruding yet.
Description of drawings
Fig. 1 is the structural representation of U font extracting tool in the prior art;
Fig. 2 is the utility model linear pattern draw-off gear structural representation.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of linear pattern draw-off gear, comprise locking head 1, mandrel 2, handle 3, block 4, front end at mandrel 2 is provided with locking head 1, mandrel 2 be provided with can before and after the handle 3 that slides, be provided with the block 4 that can stop that handle moves in the rear end of mandrel 2, in the middle of the handle 3 is cylindrical column 5, the two ends of cylindrical column 5 extend to form step 6 laterally, and the shape of handle 3 is exactly that two ends are thick like this, and are middle thin.
During linear pattern draw-off gear dismounting needle, operating personnel utilize locking head 1 that the locking of needle rear end is blocked, cylinder 5 that holds in the middle of the handle 3 then, another hand props up the rear end of block 4, operating personnel drive handle 3 and exert oneself backward, and handle 3 rear ends are owing to the block 4 of inertial impaction mandrel 2 rear ends, and locking head 1 of every bump can drive needle and move a bit laterally, behind the bump several, needle will be pulled out easily like this.Adopt this kind dismounting mode, operating personnel can apply strength simultaneously by two hands, and unlike U font extracting tool, only exert pressure by a hand, the feel that causes the application of force is to ten minutes pain, the utility model is to pull out needle by handle 3 bump blocks 4 simultaneously, operating personnel do not need to use for a long time very big strength to come the drawing needle, have saved muscle power, have improved removal efficiency, also further reduce the pain that hand is felt owing to violent extruding, avoided the scuffing and the incised wound of hand.The shaped design of the utility model handle 3 is that two ends are thick in addition, and is middle thin, thin position in the middle of hand is placed on, and hand is not easy to come off from handle 3 in drawing process like this, has guaranteed the reliability and the speed of dismounting.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
Claims (2)
1. linear pattern draw-off gear, comprise locking head, it is characterized in that: also comprise mandrel, handle, block, be provided with locking head at the front end of mandrel, mandrel be provided with can before and after the handle that slides, be provided with the block that can stop that handle moves in the rear end of mandrel.
2. according to the described linear pattern draw-off gear of claim, it is characterized in that: described handle is a cylindrical column, and described cylindrical column two ends are thick, and is middle thin.
