Description
Technical field
The present invention relates to automobile die field fields, and in particular to a kind of big machine oil reserves plastic oil pan and its big back-off
Manufacture mold.
Background technique
Oil sump is the important component of car engine lubrication system, and market demand engine extends work and use
Period reduces maintenance and replacement machine oil number, needs a kind of oil sump that can increase machine oil reserves；
It is mostly metal oil sump on existing market, at high cost, weight is big, and installation is inconvenient.Processing technology is single, can not
Complicated product structure (space can not be increased with back-off form in oil storage chamber) is made, small part plastic oil pan is mostly side
Wall is faced directly can not increase volume on the basis of existing.
Summary of the invention
Present invention seek to address that the above problem, provides a kind of big machine oil reserves plastic oil pan and its big back-off manufacture mould
Tool, big machine oil reserves plastic oil pan is made of plastics, and compared with metal oil sump, plastic oil pan component weight is light, designs
Freedom degree is big, processing technology is various, deisgn product structure can be more complicated, using inner cavity back-off form increase oil sump in
Volume can increase the reserves of machine oil；Big back-off manufacture mold can be used for producing the modeling with big back-off structure of the application
Expect oil sump, the big back-off structure of plastic oil pan can be avoided when demoulding by separable mold core, and then complete to take off well
Mould operation, performance are stablized, and the technical scheme adopted is as follows:
A kind of big machine oil reserves plastic oil pan, it is characterised in that: it is integrally formed by crankcase pit top section and crankcase pit bottom section,
The leading flank of the crankcase pit bottom section is located at the front of crankcase pit top section leading flank, and the trailing flank of the crankcase pit bottom section is located at oil
The rear of bottom case top trailing flank, the distance between described crankcase pit bottom section front and back sides be greater than crankcase pit top section front and back sides it
Between distance, seamlessly transitted between the crankcase pit top section and crankcase pit bottom section, form back-off part in front side and rear side respectively.
A kind of big back-off manufacture mold for manufacturing above-mentioned big machine oil reserves plastic oil pan, comprising: preceding mould and rear mold,
It is characterized by: the rear mold includes: rear mold main body, intermediate retrogressing sliding block, left slide bar, right slide bar, left slider and right sliding block, institute
The front side for stating rear mold main body protrudes forward is formed with the first mould core portion, leads in the rear mold main body with what front-rear direction opened up
The slideway that slot and left and right directions open up, the left slider, it is intermediate retreat sliding block and right sliding block be combined from left to right in
The second mould core portion is formed together, and the intermediate sliding block that retreats can be separated with left slider and right sliding block, second mold core position
In the through slot of rear mold main body, front end exceeds through slot, and the part beyond through slot collectively constitutes mold core with the first mould core portion；Mold core
Shape and the shape of oil sump inner cavity match, the left slide bar and right sliding bar are connected in slideway, the left slide bar
Right end and left slider Joint, the left end of the right slide bar and right sliding block Joint.
The invention has the benefit that the big machine oil reserves plastic oil pan of the application is made of plastics, with metal oil bottom
Shell phase ratio, plastic oil pan component weight is light, design freedom is big, processing technology is various, deisgn product structure can be answered more
Miscellaneous, the application increases the internal volume of oil sump using inner cavity back-off form, can increase the reserves of machine oil；The big back-off of the application
Manufacture mold can be used for producing the plastic oil pan with big back-off structure of the application, when being demoulded by separable mold core
The big back-off structure of plastic oil pan can be avoided, and then completes stripping operation well, performance is stablized.
